B. flat pieces of hosiery.

A main object of the invention is to provide one for use used in knitting machines for the production of appropriately shaped hosiery novel and improved double edge device that is simpler and more compact in the execution is in a machine of the usual type with a minimum change in the conventional drive devices of this machine can be installed more easily and well suited for fully automatic operation in connection with the various mechanisms of action of these machines is to produce a double edge product, the production of which comprises: Casting on the initial row of stitches of the double-edged fabric, knitting and folding the double edge goods and the opening of the initial row of stitches of the double edge a row on the needles to close the double edge. the the subject of the invention forming double edge device is for striking the Starting row of stitches as well as for opening the stitches of the starting row of stitches provided with double-edged tools on the needles of the fontur, which are used in the construction and in the Work essentially similar to those tools that are used in the American Patent specification 2 269 463 by L i e b e r k n e c h t shown and described became.

The invention means an improvement in construction in many respects and the arrangements described in the aforementioned U.S. patent by L i It is not possible to find the parts shown and described.

Another object of the invention is to improve the structure and the cooperation of the double edge and knitting devices working together the machine and the associated switching devices to the double edge and the associated length and foot parts of the stocking blank to work more effectively.

The double edge device set forth here, which in a preferred The form which contains the various characteristics of the invention is of the general type Type made up of a series of double-edged hooks, the vertical shaft parts and upwardly having hooks grooved on their outer edges, the Double edge hooks are so far apart from each other that a row of sling stitches is only formed on every other needle. While working the: @ weft stitch row will be the double edge hook with respect to the chair needles vertical, forward and backward Backward movements are given to make the thread loops from the second chair needles alternating needle sticks or hook sticks to press off and then into the hooks to hang up. Then later the double edge hooks are again with reference to the chair needles moved to transfer the initial row of stitches back to the chair needles and thereby closing the double edge.

According to the invention, the support and drive structure for the double edge hooks in each fontur of the machine a series of backward-facing levers, the from one some distance below and forward of the machine's work table lying rotating shaft, and also includes two upwardly directed Double-edged liaison arms, which are used to move forwards and backwards around rotary joints be carried around by the aforementioned twin edge lifters. The movement of the horizontal lever in a vertical plane and the movement of the double edge hook support arms in a forward and backward direction is cams of a double edge camshaft controlled that below and slightly backwards of the work table and above the The main camshaft of the machine is located. The required vertical movements will be the double edge liacs are given by means of cam levers, which are fixed to the horizontal Double edge lever bearing rotating shaft are connected and located below the double edge camshaft extend. The vertical position of the double-bordered liacs will continue during the Section of the double edge production, which is the production of the start stop row connected, controlled by means of cooperating locking and ratchet levers, which operate automatically switched to the vertical working height position of the double edge hook during determine each of the various successive stages of double-rim manufacture. To move forward and backward the double edge support arms and the one carried by them To grant double edge hooks, cam and rotor connections are provided that contain an oscillating shaft located at the rear of the work table, which via cams and compliant rotor levers are rotated and to which push lever arms are attached, to press against the associated double-edge support arms and these in the backward direction to move. The structure and arrangement of the cam and rotor connections for the Double edge back and forth movement is chosen so that only a resilient force is expended to the double edge hook support arms and the double edge hook in the Move backwards.

For a safer and more reliable regulation fier the setting and moving the double edge hooks in forward and backward directions, in particular to have while the row of stop tabs is working is a new type of underlay or stiffening device is provided for the double-edge hooks that hold against the Double edge support arms acts essentially in the double edge hook height. This washer or stiffening device consists of a series of stiffening plates that between and on the eggs of the various fountains or workplaces on upwards directed lever arms are set up, which sit on an oscillating shaft on the one or more downwardly facing cam levers are mounted to engage to step on the double edge camshaft seated, cooperating cams. the Support cam levers and plates are used during the manufacture of the sling row set up to provide a secure base for the double edge hook during the pressing process of the needle loops from the second needles, and then again Brought to work to the forward and backward position of the double edge hook to regulate during the forward and downward movement of the hook, for the purpose of that to push the discarded thread loops forwards and hang them in the hooks.

According to a feature of the invention there is a novel and improved Setting up and cooperation of the various drive shafts of the machine thereby achieves that the oscillating shaft moving the front catch rail (distribution rail) of the machine together with the associated support arms and cam levers backwards from of the main camshaft substantially above the rear lower rail of the machine is mounted to provide sufficient space for the double edge camshaft in the preferred storage below the work table and above the main camshaft to accomplish.

Next in accordance with the invention are the various double-edged bars connected along the machine with the support arms in such a way and sit in such Way on the support arms that any greed double edge bars by the operator can be easily removed for easy access to the parts underneath the bar of the mascliiiie, and then by the operator in a precisely set Position can be easily reinserted.

In the machine shown, each double-edged bar carries on its : Middle part of an upward arm that is between two relatively fixed l @ insteil screws is fulfilled by the rabbet support shaft of the lowering machine be worn around the various double edge hooks with the cooperating Needles to be set up exactly as soon as the Hakeii is in working position with reference to the Needles in the course of the work processes when casting on an initial row of stitches Double-edged fabric and later when transferring the initial row of stitches back to the Needles to close the double edge are moved forward. The face alignment of the individual double edge bars in the manner set out above has been found to be an essential one Improvement in the management of the individual over the previously used procedures Double-edged bars by means of curls located on opposite ends of the same have been proven, since the realignment is simpler and less costly to manufacture, easier and can be adjusted more precisely and essentially unaffected by the expansion or shrinkage of the metal parts as a result of Teniperatttr change.

Further according to the invention, the Doppelrandvorriclitung and associated knitting tools specially designed and arranged to one on each Second needle hanging cast-on stitch row of small, firmly formed i @ -lascheti to build. The "orriclitig" by which these meshes are formed "- contains a special needle press cam used when hitting and one associated with it special chain length regulator for the initial row of stitches that is used when manufacturing the stop vias can be brought to work. to adjust the needles so that the against the shafts of the needles by working the usual sinkers and distribution sinkers formed thread loops are much smaller than usual on which: machine could be worked. The thread loops formed in this way can, for example, be of a length in the region of half the length of that thread loop be. which would be made for an ordinary mesh on the machine. the Double edge hooks of the machine shown are specially designed and arranged, to work together with the needles in the formation of the initial row of stitches and the thread loops formed in this way from all second needles essentially knock off above the usual pressing position. During the subsequent relative movement of the needles and the sinkers is when the needles are down against the knock-off point move, the thread given by the loops cut off the length of the Added thread of the remaining loops, which in this way were given a length which is equal to the length obtained by knitting an ordinary stitch, so that the relative adjustment of the needles, sinkers and knock-off comb teeth for the Stitch length as soon as the needles down past the press and to the knock-off position move, can be kept essentially unchanged.

Also in accordance with the invention is a novel and improved construction and arrangement of the double edge rod trigger device is provided, the double edge rod trigger hook and includes endless haul-off chains that are resiliently connected to a weight-loaded Have a take-off shaft. The double edge bars are before the time of their use held in holders carried by the associated edging bars of the machine will. The double edge rod pulling devices consisting of chains and pulling hooks are held in a preset position and work with a sham movement the lowering machine and the edging bars together for automatic loading to effect the double edge rods and peel off a fold of the double edge goods. While the device for lateral displacement of the edge bar, that would usually work with the lower machine, in non-working position set.

An automatic device for controlling work and for readjusting the double edge rod pulling device is provided that from a ratchet and pawl link operated by the main camshaft of the machine there is a step-by-step process after the weight-loaded trigger shaft has been inserted Rotation in reverse direction granted to readjust the double-edged rod trigger. The haul-off chains and hooks are in their newly set position by means of a Pawl held, which is actuated by touching the double edge rod as soon as the rod is held in working position to engage the hooks with the Release double edge bars. The work of the readjustment pawl and ratchet wheel connection is used both to begin and to end the readjustment process with a Movement of the double-edged bar haul-off chains controlled.

According to one characteristic of the invention is a novel thread cutter provided, which is automatically actuated according to the settings of the pattern chain is around the clamped end of the double edge thread at the beginning of the double edge knitting process cut through. In the preferred form of the device the thread cutter has the Shape of a knife arm that can swing on a the girder bridges is stored for the double edge rod pull-off device. The knife will work automatically controlled by the double edge rod pull-off chains and hooks issued pseudo movements, which have the effect that the knife is automatically pivoted and reset. Around The tensioning device provided on the machine is used to get the thread knife to work Brought to work for the double edge rod deduction, around the double edge rod deduction chains and hook back a short distance from the reset position to move, and then returns to the reset setting. The subsequent Movement of the double edge rod haul-off chains and hooks in the forward direction after release, in order to grasp the double-edged bar and pull off the double-edged goods, causes the Resetting the line knife.

According to a characteristic of the invention, the double-edged goods take-off trained in such a way that he only works during part of the production of goods, and although during the production of the double edge and part of the length. While the weight of the double edge rod is sufficient for working the lower length and the foot and the finished goods together with the the knitted goods on the back of the needles pushing effect of the grooved absc. hilt combs shown here to ensure a permanent To maintain transfer of the knitted goods into the container receiving the goods.

The automatic, step-by-step return of the double-edged bar pull-off chains and hook is used during manufacture of the lower length and foot of the stocking blank carried out so that the double edge rod deduction is completely reset before the The finished group of stocking blanks is pressed off.

Furthermore, according to the invention is a device for automatic Control of the work of the lowering machine in connection with the double edge device provided, which contains the following parts: A pattern-controlled device for moving the lesser machine to a high non-working position for hitting and also for the stitch transfer process required to close the double edge, a pattern-controlled device for returning the lowering machine to the working position after each of the aforementioned operations and a pattern controlled device to prevent the lateral displacement of the edge bar of the lowering machine during the pseudo-immersion movement of the lowering machine and the edge bar when inserting the Double edge rod.

According to the invention, the cutting combs of the machine in a novel way carried and operated so that these tools move forward and downward only spring-loaded during predetermined sections of the knitting cycle are both perpendicular and during other predetermined portions of the cycle Direction as well as in the horizontal direction are firmly supported. In the illustrated In the TNI machine, the cutting combs are mounted on frames that are equipped with trunnions are that engage downwardly facing hemispherical bearings that are perpendicular to the movable usual knockdown comb lever carriers are formed. The tee frame and the knock-off combs carried by them move upwards in these camps and tensioned forward by tension springs. Sitting on cam operated lever arms adjustable stop screws can be in contact with the underside of the bearing journals be brought so that the spring support in the vertical direction completely switched off and instead a drive-related, cam-controlled movement of the cutting combs during part of each operating cycle according to the switching of the drive cams is set. A drive-based control of the vertical position of the tee box mme was found to be particularly desirable during the downward movement of the needles. As soon as the needles then approach the knock-off plane, they become the trunnions touching stop screws moved downwards out of contact, so that the Knocking off the stitches against knock-off combs that are spring-loaded in the vertical direction can be done.

A special group of knock-off combs is used for minor maneuvers actuating cams provided, which act to a drive-related control the position of the cutting combs in the vertical plane during the entire lowering cycle to maintain through it.

Furthermore, according to the invention is a novel and sophisticated one : Arrangement of pattern-controlled switching parts provided to a substantially uninterrupted and automatic working of the it machine to reduce the double edge trim to secure a knitted stocking blank. These switching parts, which will be detailed later are set out, contain an auxiliary device in one of the Ansclilaginasc @ lenreilie and the operation preceding the double edge transfer is brought to work and which works automatically to the single-turn clutch of the double-edged camshaft the machine and, after a corresponding time delay, the double edge camshaft to move axially, in the first-mentioned case in a position to stop and in the second case to the double edge transfer position.

The drive connections, through which the forward and backward movements are transmitted to the needles, order from a downwardly directed arm 128 which is provided for two fonts each and forms part of the support frame 121, which by means of a vain I_enl: ers 129 tnit a downward directed lever arm 130 is connected, which is attached to the oscillating shaft 131 extending along the machine. clie swivels the needles in and out of the pressed position. The tension spring located between a rear extension of the link 129 and a console on the platinum head rail 112 tends to oscillate the link 129 and the lever 130 in the left-hand direction, as seen in FIG. 3. The shaft 131 is provided at intervals along its length finitely downwardly directed cam levers 132 (Fig. 10), each of which carries a cam follower 133 for the purpose of cooperation with one of three Nztclelrtocl <eti on the main camshaft 120, similar to the usual press cam 134, a minor cam 133 and a special PressnOc] #ett 136 for the vain small mesh size of the Ans (-lilagniasclietirreihe.

The NOCketlliel) el 13, which moves the needles back and forth, is with a downwardly directed 'feil 137 and a pin 138 provided by (Learn the usual stitch length control lever 139 is adjusted, which is on the the entire length of the machine extending control shaft 14o is seated.

Eitle bIaschenlärigen control device of the usual embodiment for Adjustment of the angular position of the control shaft 140 is generally shown in Figs io of the drawings. The device includes an adjustment cam lever 141, which is loosely ripped on the control shaft 141, and has a forked end part 142 to accommodate a Scllwittgz21l> fetls 143 has. on your a cam follower 144 for the purpose of cooperation with a control cam 145 ;; is guidable. The angular position the control shaft 140 with reference to the control cam lever 1.41 is set by means of a cam lever 146, which in turn is fastened on the control shaft 140. the The hub of the lever 146 is fork-shaped, overlaps the hub of the cam lever 141 and is splinted onto the control shaft. An adjustable one carried by cam lever 146 Stop screw 147 is connected to a stop surface on the cam element 141 together. Dic: rule shaft 14o is finite together with the levers attached to it counterclockwise, joined in Fig. 6, urged by a strong tension spring i 4, X, attacking on an upward: \ rtn 149. Hurried between the rule liver 141 and cam lever 146 engaged tension spring 15o endeavors to the stop screw 1.47 in contact with the surface of the cam lever 141. According to the invention are the `` Virkwerkzeuge '' and the double edge stop hooks of the machine shown so designed and arranged that they work together in a novel `` '' way. To close a row of cast-on stitches hanging with one stitch on every other needle which consists of small meshes (compared to the relatively large open stitches, which are usually used when forming a row of cast-on stitches with a stitch on every other needle), it is suggested that as is customary to throw off the loop from every other needle, whereupon the thread forming these stitches on the double edge hooks, one of which each is provided for every second chair needle, so that the initial cast-on stitch row lies between the needles in between and the double edge stop hooks. Will If this operation was carried out in the usual way, this would be the production a row of sling stitches full of relatively large stitches result, because the length of the thread coming from the stitches thrown off corresponds to the length of the remaining ones Between stitches must be added.

According to the invention are the above-mentioned special stop press cams and a special mesh length regulator cooperating therewith provided which act there, the needles in an extraordinary forward position during the Kuliervorganges to provide, so that a thread length is measured to the needles, which is much smaller is called the length necessary to work the tightest mesh on each Machine is required. The very] <linen needle loops formed in this way or half loops are immediately reduced in number to half and take turns by shedding every other loop over the hooks Needles increase in size significantly once the needles move down against normal Move the press position. As soon as the loops go down to the usual Move press position past to be reshaped on the knock-off comb, the lengths of thread originally looped around the shafts of every second needle the length of the intervening needle loops so that the needles move downwards can move towards the teeing position in an essentially conventional manner. The meshes the row of cast-on stitches hanging on every other needle, which is now through the Downward movement of the needles to the knock-off point and pulled by the double edge hooks are captured, have the length of a normal single stitch, as they are when working an ordinary_ row of stitches of the length of a stocking.

In the illustrated embodiment, a special cam is used which is used to move the needles to an exceptionally low level at the knock-off point in order to most effectively cooperate with the stitch-picking movements of the double-edged hooks in the cast-on stitch row. Characteristics of the implementation according to the invention, which enables the knitting of a small stitch size hanging on every second needle, are an improved design and arrangement of the device for moving the double edge hooks in order to obtain a more precise and reliable control of the movements, as well as a special stitch length regulating device that switched on to measure the number of stitches formed in the row of cast-on stitches. The stitch length regulation is effected during the preparation of the stop stitch row by means of the special stop needle press cam 136 , which works in cooperation with a stop row stitch length regulator (Fig. 5 and io). The special regulator mentioned contains a special control cam 152 which is fastened on the main camshaft i2o and which is able to act on a rotor 153 which is displaceable on the journal 154. The pin i54 is carried by a fork lever 155, which sits on the control shaft i4o. The position of the rotor 153 is controlled by means of a shift fork 156, the hub part of which is loosely attached to a sample shift rod 157. The movement of the shift rod to the right when the sample chain 309 is shifted tensions a spring 158 lying on the shift rod 1-57, which tries to bring the fork 156 and the runner 153 flexibly into alignment with the special control cam 152. A ring 159 fastened on the rod 157 can lie against the right side of the shift fork hub in order to bring about a return movement of the shift lever 156 and the rotor 153 with the rod 157 into the starting position.

The sinker boards io4 and the distribution boards io6 have the usual ones Embodiment and the usual operation of these parts. The one with the distribution boards io6 along the entire row of needles of the fontur alternating sinkers 104 are successively in a knitting shaft that follows the passing of the working thread guide, lengthways the row of needles of the fontur advanced. The thread gets onto the shafts this way measured or calculated for each pair of needles. The distribution boards in between are advanced in it, the thread is taken from the adjacent sinker loops, around an evenly spaced row of loops of thread on the shafts of all needles to build. The sinkers are moved by a machine that moves in the longitudinal direction of the machine Steed advanced, the drive mode of which is known and therefore not described here will.

The device for moving the distribution sinkers and for pulling back the sinker sinkers and the distribution sinkers before the knocking off and during the knocking off of the stitches contains a catch (distribution) rail 162 (Fig. 7) which is supported and controlled by a front and rear catch rail drive, to carry out the usual operations of a safety rail in these machines. The rear safety rail drive, which consists of vertically arranged levers on which the safety rails are pivotably mounted in order to carry out forward, backward and vertical adjustment movements, is of a form known in the art and is not shown further here. A representation of the rear safety rail drive can be found in the American patent specification 2,269,463 by Liebknech t. The front fatig rail drive used, which is used to give the safety rail Aufundab-I @ ewe: @unnen, is of new and lost design. As can be seen from FIG. 7, the catch rail i62 has arms 163 which are directed forwards at intervals along its length and which are carried at their front ends on vertically standing front links 164, which can swing at their lower ends with horizontally directed lever arms 165 of an oscillating shaft 166 are connected. The operation of the oscillating shaft 166 is controlled by means of one or more cam levers 167 which are mounted on the shaft at intervals along its entire length. Each cam lever 167 carries a rotor 168 which is actuated by a cam 17o on the main camshaft i2o. The attached at the end of the cam lever 166 coil spring 172 keeps the runner 168 at all times in contact with its cam 170. It can be seen that this front safety rail drive described above is novel in that the front safety rail swing shaft from its usual storage below and something is shifted rearward of the machine table 118 to a position above and rearward of the lower rear rail i 1.1 and is supported by this rail by means of brackets 174. The new arrangement of the front catch rail swing shaft creates free space for a double-edged camshaft with a large diameter and working cams, which will be described below.

The knock-off comb teeth io8, which are best seen in FIGS. 4 and ii and also from FIGS Frame iSo sits. At each end, the frame is equipped at its lower edge with downwardly directed arms 182 in which horizontally directed pivot pins 184 are seated on which the frame and the knock-off combs can swing back and forth. Each cut-off chamber dimension is also held and guided at each end in a console 186 screwed to the sinker head rail 112. The consoles 186 prevent longitudinal movement of the frame and are also equipped with cover plates 188 which serve to limit the forward movement of the knock-off comb frame 18o away from the sinker head rail 112. The closing comb frame i8o and the chopping bar 178 are urged in the forward direction by means of tension springs igo, which are inserted between lugs igi on the frame i8o and adjustable links 192, which can be adjusted with their front ends on downward-facing brackets attached to the underside of the machine table 118 i94 sit. The position of the cutting comb frame i8o is regulated forwards and backwards against the pressure of the springs igo by means of two upwardly directed arms 196 which are carried at their lower ends on an oscillating shaft 198 and which bear with their upper ends against lugs Zoo on the front surface of the cutting comb frame 18o. The arms 196 are rotatably connected to the rocking shaft 198 by levers 202 which are rigidly seated on the shaft 198 and which are connected at their upper ends to the arms 196 by adjustable screws 204. Oscillating movements are transmitted to the oscillating shaft 198 by means of cam and cam follower gears from the main camshaft i 2o via linkages which consist of one or more forward cam lever arms 2o6, each of which carries a corner runner 2o8 which is pressed against the circumferential surface of a cam 2io is, the back movement of a tee comb forward. causes. A strong tension spring 212 holds the cam lever 2o6 and runner 208 in contact with the associated cam 210. In the embodiment shown, the cutting structure consisting of the cutting prongs io8 and the cutting comb frame 18o is arranged so that it can move in the vertical direction by means of a device that either a drive-related up and down movement or a spring-loaded downward movement depending on the working de ,. different parts of the stocking blank are able to perform the required conditions alternately. As best seen in Fig. ii, tension springs 214 are attached between the lower parts of the various frames and anchors provided on the sinker head rail 212, which tend to resiliently love the frame and the chopping prongs upwards. The pivot pins 184, about which the cutting comb bars swing forwards and backwards, are swingably suspended and are held against upward movement under the action of the springs 214 by means of two forward-facing arms 216, which are mounted on a swing shaft 22o and ride semicircular, downward-facing wings for receiving the pivot pins 184 are provided. The pivot pins are adjustably supported in the wings by means of adjustable sliding mounts 28 that are screwed into the arms 216. Oscillating movements are transmitted to the oscillating shaft 22o by means of one or more cam lifters 1222, each of which extends downward from the shaft 22o and has a rotor 224 at its lower end, which counteracts a cam 226 on the main camshaft 120l that causes the vertical movement of the knockout bar 'iuft. A strong tension spring 22.9 acting against the lower end of cam lever 22o is sought. hold the runner 224 in contact with its associated cam.

According to the invention there is provided a device which can be switched on at will in order to switch off the downward guidance of the knock-off combs under the influence of the spring 2r4. This device consists of an oscillating shaft 23o which lies immediately below the oscillating shaft 220 and to which are attached laterally directed arms 232 which carry adjustable stop screws 234 for the purpose of engaging the underside of the oscillating pins i84. In order to impart oscillating movements to the oscillating shaft 230 , one or more cam-actuated levers 236 are provided on which cam followers 238 are seated, which run on a circumferential surface of the drive cam 240. A strong tension spring 242 connected to the lower end of each lever 236 keeps the runner 238 in constant contact with the cooperating cam 24o.

The way in which the tee combs work while being knitted, will be described below with reference to FIGS. 64 to 71 schematically. As already stated above, the knockdown ridges are in the forward and vertical direction spring-loaded, and the pivot pin around which the knock-off combs rotate is additionally adjustable, uni a fixed support in the vertical plane in place to form the spring-loaded carrier. The through the tee teeth in; a vertical one The various positions assumed are particularly evident in the schematic plane Figures 64 through 71 are shown. For a more effective working of the knock-off combs proposed according to the invention, a solid vertical support for the knock-off combs during the first part of the cycle until the needles move downwards to the press and including this movement. Especially during the downward movement of the needles is a safe control of the vertical position the discount would be an advantage to prevent the goods from frictional contact of the stitches on the needle shafts is pulled, and to ensure that that these stitches are moved over the hooks of the needles that are still closed.

Fig. 64 shows the tee tines or tee line in the partially retracted position which is maintained during couling and at a relatively deep level. Once the needles. As shown in Fig. 65 and 66, approach the press position, the knock-off combs are moved slightly backwards in order to guide the backward movement of the needles. The position of the cutting prongs forwards and backwards is such that any possible pull from previously knitted fabric which would interfere with the pressing movement of the needles is avoided. As soon as the needles move downwards and backwards for the purpose of knocking off, the knock-off combs are moved to their highest position. At this point in time they are spring-loaded due to a relative downward movement of the carrier screws 234, which close the semicircular bearings for the knock-off comb frames. In the positions shown in FIGS. 68, 69 and 70, the knock-off combs are spring-loaded in both the horizontal and vertical directions in order to withstand the pull of the thread legs as soon as the needles carry the stitches downwards and backwards between the knock-off combs. The arrangement described above, in which the knocking combs are fixedly mounted in a vertical direction, in particular during the downward movement of the needles during pressing, has the advantage that a firm and reliable regulation of the vertical position of the knocking combs is created. So that the position of the end meshes of the previously formed goods held on the shafts of the needles can be precisely and reliably determined, the subsequent spring mounting of the knockdown combs during the downward movement of the needles towards the knockdown position has the particular advantage that the knockdown surfaces act to keep the knocked-off stitches under one to maintain correct tension without the need to adjust the knockdown combs according to the stitch length produced.

The working of the tee combs during the soothing is special shown in the schematic FIGS. 72 to 8o. As can be seen from FIG. 72, it is possible the cutting combs move forward at the beginning of the lessening process. The parting the cutting teeth are at a sufficiently low level at this point in time, so that no thread is pulled from the sinker mesh and the goods on the surface the cutting teeth, including the grooves, lies. As soon as the minor needles have their Continue downward movement to cover the chair needles and pick up the tabs, which are to be imposed in the longitudinal direction of the row of needles are the knock-off combs still held in this relatively retired position. As soon as the Lift the needles to remove the stitches from the chair needles the knock-off combs moved upwards at the same time to aid this process. During the lateral transfer movement of the minor needles, the knock-off combs, as shown in Fig. 76, depressed so that the underdecks from the apex the cut-off combs continue to stand at a distance. During the subsequent transfer process, shown in Figs. 77 to 79, the knock-off combs are moved forward, so that the throats of the knock-off prongs are the stitches of the goods held on the needles hold down. As soon as the underdeckers move upwards over the tee combs and the needles will enter between the sinkers as shown in Fig.8o the knock-off combs are withdrawn again into the position shown in FIG. 72. In the illustrated preferred embodiment of the invention are during this the entire process the knockdown combs during the entire minor process in a vertical position Direction firmly stored.

The reduction device shown generally in Figures 5 and 6 of the drawings contains a support rod 246, which on lever arms 2: I7 at spaced locations is mounted over the entire length of the machine, around an oscillating shaft 248 (hig. 6) to swing and the reducer towards the needles and away from the needles to move. The usual cover or lesser needles for carrying out framing work are shown generally at 249 (FIG. 9) and are followed by a left and a right minor rod 23o carried, which is slidably mounted in hanging brackets 25i that sit on the support rod 246. The lowering machine also carries an edged needle bar (Pickot bar) 252 for each font. each edged needle bar 252 is driven by an edged needle bar shaft 253 supported rotatably in bearings provided on the brackets 251. In accordance with customary practice, the edged needle bars are arranged so that they are in the rest position be turned upwards, as shown, for example, in FIGS. 2 and 9 is, and then folded down into the working position, as shown in Figs and 12 as well as in dash-dotted lines in Fig. 2 is shown.

The lowering machine is in the vertical direction by means of rods moves, which can be of the usual type and one or more vertical links 254 (Fig. 5 and to) contain which are spaced over the entire length of the machine stand from each other, at their upper end with the lowering machine frame and at their lower end are connected to a Nockenliebel255, the runner 256 during of normal working out is engaged with a circular disk 257 while of the lowering process but cooperates with a cam 258 for lifting the lowering machine.

In the preferred form of the 1lascltine shown, a high-lift device is provided in order to raise the lowering machine to an exceptionally high position out of the path of movement of the double-edge device during the stopping and turning of the double-edge device. The high-lift device contains an oscillating post 239 which is rotatably mounted on a pin 26o in a lever 261 which is firmly seated on the oscillating shaft 262. An arm 263, a supporting arm 264 and a Nockenläüfer a Fußtrethebe1265 also fixed to the oscillating shaft 262nd The post 259 is resiliently held in contact with a stop screw 266 on arm 263 by means of a spring 267 so that when the shaft 262 is moved clockwise, the post engages a detent in the end of the Lä uferhelyels 255 and upon further rotation of the shaft 262 the Runner 256 lifts off its cam disk 257. A tension spring 268 attached to the cam lever 264 tends to pull the cam lever 264, the rocker arm 263 and the associated parts counterclockwise into the position shown in FIG. 5, in which the foot lifter 1265 grips under the lower front rail 16 of the machine.

The cam lever 264 carries a pin 269 on which a NOCkerilifer 27o is slidably supported. A shift fork 2; 1, which engages in a grooved part of the hub sleeve of the cam runner, is used to move the cam runner into and out of engagement with <learn 1loclilitil>aiitriel> snocken 273. The proximity of the shift fork 271 is on one side by a ring attached to the sample shift rod 272 274 is limited in its movement and is acted upon on its other side by a spring 275 which is braced against a ring 276 fixed on the switching rod 272. As can be seen from FIG. 10, the hub collar of the shift fork 271 also has a downwardly protruding bracket 277 in order to be able to be actuated by a catch 278 which is splinted onto a second sample rod 279 for a change.

During the movement of the rocking shaft 262 and its associated "heal" including the treadmill 265 in a clockwise direction into a working position in which the post 259 engages the catch of the lower machinery, the lifting cam lever 264 causes the treadle under the grooved lower 1? Llde a bolt 2810 occurs, which is carried on a pivot pin 281 on the lower front rail 116. An upwardly directed arm of the locking lever 28o carries a pin 282, which lies in the position of a flag 283 which is loosely attached to a sample rod 28.I atlfgel The catch is limited on one side by a ring 285 splinted onto the sample rod 284 and is acted upon on its other side by a compression spring 286 which rests against a ring 287 fastened on the switching rod 284.

The first step of the sellisttiiti <#, en device shown in FIGS. 5 and 10 for lifting the lower neck tube is briefly as follows: In the movement sequence preceding the hitting, a derailleur shifts the shift rod 272 to the right into the one shown in FIG `i-. io position shown, the slider 272 the shift fork 27, and the runner 270 ll1itllinltl1t, which in this way is brought into finite alignment with the high-lift cam 273. The tip of the lift cam 273 causes the slider shaft 262 and the associated Parts in a clockwise direction out of the position shown in FIG Bolt 280 moves and in this way holds the parts in the extraordinarily high position. The linder machine remains in this high position until the bolt is removed. After the locking operation of the lowering machine in the upper position is completed, the sample bar 272 returns to its original position Likewise, the rotor 270 turn the shift fork 271 into the position shown in FIG Spring 275 returns as soon as the contact pressure finite the dome of FIocliliul) IIockell 273 is no longer effective.

According to the invention, the above-described master device is used to automatically reduce the machine. as soon as desired to lead back down into their working position. For this purpose, the shift rod 279 (Fig. 10) and lug 278 are moved to the right, so that lug 278 takes the lever 277 with it to move the shift fork 271 and the runner 270 back into alignment with the high-lift cam 273 which, as soon as the runner comes into contact with the tip of the cam, works to pull the tension on bolt 28o. At the same time, the switch rod 284, actuated by a button on the pattern chain, is moved to the right, which the spring 286 (Fig. io) which, as soon as the load on the bolt 28o is lifted, brings the bolt 28o out of engagement with the foot pedal 1265. When the high-lift cam follower 27o now moves the cam descent of the high-lift cam 273 downward, the oscillating shaft 262 can oscillate counterclockwise, whereby first the lowering machine and its stroke runner 256 are moved into the working position shown in FIG. 5 and then the post 259 is removed from the detent in the end of the cam lovel -> 55.

The high-lift device is actuated during the double-edge turning process in a manner similar to that described in connection with finite hitting, with the exception, however, that in this case the shift fork 271 and the high-lift cam rotor 27o are shifted to the right to initiate the high-lift cycle described above by a movement the sample shift rod 279 and the Kllagge 278 is executed to the right, which acts against the KOtls0le 277 of the shift fork 271.

The edged needle bar 252 is typically shifted to the right by one needle pitch during the loosening and transfer of stitches of a regular row of edging flaps. The offset device, as shown in FIGS. 6 and 12 of the drawings, consists of a shift lever 29o which is loosely rotatable on the 1Minder machine shaft 246 and finitely equipped with a downward arm which is able to contact a ring 291, which is splinted onto the edged needle bar support bar 253. The locking jack 129o also has an upwardly forked arm which includes a lower machine auxiliary shaft 292 which is rotatably supported in bearings on a cylinder machine frame. A cam ring 293 mounted on the roller 292 is capable of having a cam surface on the extension full Hel> e129o and acts to give your lever29o, the ring 291 in contact with the lever and the support rod 253 carrying the needle bar an offset movement to the right as soon as the shaft 292 is swung out. The carrying rod 2S3 carrying the edge needle bar is usually held in the left 1 position by a spring device of the usual type. In order to bring about the above-described displacement movement of the needle bar, the auxiliary shaft 292 is given oscillating movements by drive connections which contain the following components: 292 attached lever arm m 294; a handlebar 295; a loosely oscillating lift 1296 which functions to rotate on the lower machine rocker shaft 248 at the rear of the machine; a downward facing link 297 and a cam operated 1-lebel298 swingably supported at 299 on a bracket 300 attached to the lower rear rail 114. The cam-operated lever 298 is provided at its front end with a support pin 303 on which a cam follower 302 is slidably seated for engagement with a cam 303 wedged on the main camshaft 12o. A strong tension spring 304 connected to the forward end of the cam side actuated lever 298 usually seeks to place the runner 302 in contact with its drive cams 303 . A downward arm of the cam operated lever 298 carries an adjustable stop screw 3o5 which abuts the lower rail 114 to limit the movement of the lever under the influence of its spring 30.4.

The device for axially displacing the main camshaft 120 for the purpose of bringing the lower machine cams including the above-described edging bar offset cam 303 into the drive position is shown generally in FIGS Moving cam track 307 is, which is formed on opposing surfaces by cam disks 308 firmly seated on camshaft 120. Since this device for displacing the camshaft 120 is known in the art and is switched in the usual manner from the sample chain of the machine, further explanation of the same does not appear necessary.

In accordance with customary practice, the operation of the machine is controlled from a pattern device which is in the form of a pattern chain 309 carried along the machine on sprockets as shown at 310 and 311 in FIG. At its left end, the pattern chain runs around a drive rod supported by a support pin 313: ettetitromme13i2. A stepped indexing motion is imparted to the chain in timed fashion with respect to the revolution of the main camshaft 120 during the action of a stocking length by a cam operated device which includes a cam 314 and a cooperating cam follower bearing arm 315 which is swingable on a Console 316 is mounted on the lower front rail 116 and carries a cam follower 317 on an upwardly directed lever arm. The other arm of the angle lever 315 is connected by a short 1_eilker318 to an arm 319 which carries a pawl and which can rotate loosely on the pin 313 zii. The pawl 320 carried by the arm 319 engages a ratchet 322 which is an integral part of the sample chain drum 312.

According to the invention is an improved system for automatic Control of the lowering machine provided to move the lowering machine in an upright position in out of the path of movement of the double edge hooks as well in the Ansclilageii as well as in the double rim transfer and from this H'Ocllstellung to provide back and to work the laterally offsetting the edge needle rake Device with reference to the apparent dewing movement for the purpose of working engagement to regulate the double edge rod with the double edge rod pulling hook and then the Form edge in the usual way. The movements given to the minor machine can be briefly outlined as follows: According to the instructions of the sample chain the 1linder machine is set to its high non-working position before working the Double edge cast on stitches raised. After a number of courses have been worked have been, the lower machine is automatically in its working position again lowered. At this point in time, the edged needle bars become the ones lying on them Double edge sticks by hand downwards in the working position as preparation moved to the work-locking connection of the double edge rods with their triggers. Since only a sham movement of the lowering machine is required to carry out this work process the device, which usually works automatically, becomes the lateral Displacement of the edging needle bar by a mechanical device from working held out by means of a bolt. The device for lateral displacement the edging needle bar're able to work again by releasing the latch in the movement of the double edge bar insertion process. After a half of the double edge has been worked, the lowering machine works in the usual way Way to form the edge. Again, the lower machine is in accordance with the regulation the pattern chain to its high out of work position for the double edge stitch transfer process or lifted the push-up process, whereupon the lower machine then returns to its working position is brought back.

In the machine shown, the shifting of the sample rod 272 to the right in the idle position immediately before the row of double edge stops carries out a number of tasks, which include: Shifting the shift fork 323 fastened on the rod and the needle press cam rotor 133 which is shifted thereby (FIGS. 3 and 10 ) on the stop needle press cam 136, the tensioning of the spring 335 to move the shift fork 334 and the main control cam follower 144 out of alignment with the main control cam 145 (Fig. 6 and io), the shifting of the shift fork 271 and the high-lift cam follower 2; o for the lowering machine (Fig. 10 and 5) in alignment with the high-lift cam 273 and the displacement of the Nokkeiiläufer 3o2 for the, lateral displacement of the edge needle bar into a rest position in which it is not in alignment with its cam when the lowering machine is brought to work will.

The connections for regulating the position of the cam follower 302 for the purpose of lateral displacement of the edged needle bar contain, as can be seen in FIGS. The shift fork 324 and the rotor 302 are moved to the right by action of the shift rail 272 and locked in the displaced position by means of a Z * Cgcls 326, which summarizes behind on the 1 1 'of the hub shift fork 324 t stop located. The latch 326 is carried by a fixed pivot 327 and has a slot connection finitely to a downwardly directed link 328 which is connected at its upper end to a forward extension 329 of one of the cam levers 255 for lifting the lowering machine. A tension spring 330 connected between the free end of the bolt 326 and a support pin 331 tries to keep the bolt in the locking position. A compression spring 332 located between the sliding fork hub and a Ritig 333 on the switching rod 272 is tensioned by the return movement of the switching rod 272 to the left and, after releasing the latch 326, causes the cam follower 302, which shifts the edge needle bar, to return to its normal working position. The release of the bolt 326 and the return of the sliding fork 324 as well as the cam follower 302 causing the lateral movement of the edging needle bar into the normal working position is effected during the movement causing the insertion of the double edge bars by a counterclockwise oscillating movement of the cam lever 255 lifting the lindermachine and the arm 329 from the position shown in Fig. 6, whereby the bolt 326 is lifted out of engagement with the shoulder located on the sliding fork 324.

The drive circuits for the main mesh size controller of the 'machine contain devices for disconnection operated by the pattern chain 3o9 of the machine of the main controller to adjust the stitch length while working an initial row of stitches to regulate the double edge goods on the machine. The compounds used include a sliding fork 334 (FIGS. 6 and 3), which is loosely ripped up onto a sample bar 272 and is equipped with an offset fork that connects the two surfaces of the mesh length regulator actuating rotor 144 includes. The one between the hub sleeve of the sliding fork 334 and the compression spring 335 lying on the shift rod 272 attached to the ring 336 endeavors to keep the fork in one position to the right in contact with a second To hold ring 237, which is attached to the shift rod 272.

In the double edge device, which in particular the subject of Invention forms, a double-edged bar with vertical sheets is used, which are filled in essentially the same way as it in the aforementioned American patent specification 2,269,463 of 1. i e 1) c r I; not described. According to the teachings of the cited patent a double-sided hook is provided for every second needle to create a row of cast-on stitches to form on every second 'censure. The double edge hooks are used for this purpose during the formation of the row of cast-on stitches, on the hook sides of the chair needles moved downwards, acting as pressing elements to the hooks of the second needles above to close the usual pressing level, so that the stitches are thrown off the second needles and then later, when the needles continue their downward movement, open the loops of thread that have been thrown off and held on the knock-off combs. For belching of the initial row of stitches of the double-edged fabric back onto the needles after completion the double-edged bar hooks ground the double-edged bar hooks again over the tips of the needles on the hook side of the same moved so that those held by the hook Stitches of the first row of stitches of the double edge taken up by the ascending needles to close the double edge. In accordance with the teachings of the aforementioned patent the double-edged bar and the hooks provided on it are always in a vertical or essentially vertical position during the work process for casting on the initial row of stitches, pulling off and holding the goods as well as during the opening of the stitches of the initial course on the needles for the purpose of Keeping the double edge closed.

A double-edged hook 350 as used in accordance with the invention is shown on an enlarged scale in FIG. 54. As can be seen from this figure. the double-edge hook is equipped with a curved shaft part and an elongated hook, the outer surface of which is provided with a groove, in order to pick up the needle hook alternately during the adelpreßvorganges and then again during the upward movement of the needles to open the opening stitches of the double-edged goods onto the needles. As shown in FIGS. 14 to 17 read. sit the double- edge hooks 350, which are set at a distance for the purpose of cooperation with every second chair needle, in a slotted double-edge bar 352 and are held firmly in the given position by means of a cover plate 353.

Each double-edged bar 352 is firmly mounted on two upwardly directed double-edged bar support arms 354, which are pivotably articulated at 356 at the rear ends of two horizontally lying levers 358 which cause the vertical movement of the double-edged bar and which are firmly attached to the rotating shaft that extends over the entire length of the machine 36o sit. As shown for example in Fig. 2, the vertical movement causing levers 58 go under the double edge camshaft 362, which is mounted in the frame of the machine and extends over the entire length of the machine approximately above the main camshaft 120 and below the work table 118 . The oscillating shaft 36o, vertical movement arms 358, and the double-edged bars carried by those arms are urged upward by one or more tension coil springs 364, one of which is shown in FIGS. One end of the spring is connected to a downwardly directed arm 366 fixedly seated on the rocker shaft 36o and the other end of the spring is connected to a bracket 368 fixedly seated on the lower front rail 116.

Vertical movements are the double edge hook with timing with reference to the work of the chair needles in connection with the stopping process and then again during the double edge closing or opening process by means of a Cam lever 392 or more cam levers 392 given over the entire length are distributed around the machine. The cam lever shown for example in Fig.2 and 13 392 is attached to the oscillating shaft 36o and carries a rotor 394, which is optionally one of the two cams that cause the vertical movement when striking 396 and 398 as well as one which brings about the vertical movement of the double edge transfer Can contact cams 400, these cams fixed on the double-edged camshaft 362 sit. In the arrangement shown, the double-edge hooks are flexible moved upward by the springs 364 and are during the execution of the sling and the transmission downward on the bottom of the drive by means of cams 396, 398 and 400 emotional.

The upward movement of the shaft 36o and the vertical movement of the double-edged bar under the influence of the springs 364 is limited by the contact of adjustable stop screws 37o which are screwed into the levers 358 to be pressed against the underside of a later described wave rarely to create. In various stages of the double-edged production, the vertical movement of the double-edged bar can be held in one of two lower positions by means of a downward-facing locking arm 374, which is loosely attached to the shaft 131 and has two notches, which can optionally be set with a horizontal one Lock arm 376 can come into engagement, which is rigidly attached to the oscillating shaft 360 and moves about the shaft axis with the vertical movement of the double-edged bar effecting support levers 358 (Figs. 2 and 9). As can be seen from FIG. 2, the position of the latch 374 is automatically switched by a device which includes a rearward and downwardly directed cam lever 378 which is integral with the latch 374. The cam lever 378 carries a pin 38o and a cam follower 382 which is slidable on the pin 38o in engagement with each of the two cams 384 and 386 seated on the main camshaft 12o of the machine. Pattern controlled links are provided for sliding the rotor 382 and include a sliding fork 388 which engages a grooved hub of the cam follower 382 and is attached at its forward end to a sample rod 390 extending along the base of the machine. As will be described later in connection with the operation of the machine, the double edge hooks are usually in their z. B. held in Fig. 2 shown extreme upper position as soon as the double edge bar is out of working position. The setting of the abovementioned stop screw 370 determines the height by which the double-edge hooks 350 are positioned over the heads of the needles during the first section of the double-edge hooking operation. The other two positions are an extreme low position, which is obtained as soon as the bolt 376 is in engagement with the lower or inner detent of the bolt 374, in this height position the double edge hooks with their lower ends between adjacent sinkers during the work of an initial part of the goods be held, and an intermediate position which is obtained as soon as the bolt 374 is moved clockwise a sufficient distance so that the bolt 376 1i) comes into contact with the upper detent in the bolt 374. The double edge hooks are held in place while a main part of the dol) pelrancl "N are working and especially during the period in which the double edge rods are brought into working position.

The device provided according to the invention for controlling the forward and backward movements of the double- edged hooks 350 and the double-edged bar located on the double-edged bar support arms 354 works as follows: The double-edged bar arms 354 and the double-edged bar 352 assigned to each fontur are pushed in the forward position away from the needles by connections that contain a cable 402 (Figs. 2 and 22), which is finitely connected at its free end to a front extension 404 of each double-edged bar support arm 354 and can be wound onto a drum 408, which is connected for the purpose of rotation finitely with a double-edged take-off winding shaft 41o, which extends over the whole Length of the machine extends. In this way, each individual double-edged bar is tensioned in the forward direction by means of a resilient drum connection with the double-edged haul-off shaft 410 in order to exert a haul-off effect on the various double-edged bars, while the shaft 410 is rotated clockwise by means of a weight 412 which hangs on a cable 414, which runs up around a guide roller 416 and then to the take-off shaft 410.

L: nt to swing the double-edge carrying lever 354 backwards and the double-edge hooks to lead to the hook side of the chair needles, the U'elle -12o using a cam- and rotor connections from the double edge camshaft 362 from vibratory motion eti granted. The links include one or more downward facing cam levers .f26 (Fig. t3), which sit loosely for the purpose of rotation on the oscillating shaft 420 and on their The lower eggs are equipped with a runner 428, which is equipped with a double-edged stop cam 430 and capable of engaging with the double edge transfer cam 432.

A nacligiel> ige connection is between each cam shell .126 and the rocking shaft 420 which operates the double-edged ingot support arms and the double-bordered bags are transferred backwards onto the hook side of the needles and press. As can be seen from FIGS., - And 13, the hub of the cam lever 426 on one side by a ring 436 and on the other side through the hub of a also splinted onto the `Felle 420 short lever arm .f38 touches. An offset outer end of the lever .138 carries a adjustable stop screw 44o, which rests against the cam lever 426, to the Limit relative movement of these parts in one direction. One between the Cam lever 426 and the lever arm 438 lying Shanlifecler 442 usually stops the cam cam 426 in firm contact with the lever 438. The rocker shaft 42o is influenced in the counterclockwise direction, seen in Fig. 2, by means of a tension spring 444, which are connected to a downwardly directed arm 446 seated on the oscillating shaft 420 is.

According to a feature of the invention is a device for safe Carrying the double edge hooks in a position slightly away from the pressing edge during the taking place during the beating of the beginning double-edge stitch row Needle pressing process and then safely moving the double edge hook forward over the tips of the needles after completing the pressing of the second needles intended. Safe support during the subsequent forward movement the double edge hook continues while the double edge hook moves takes place to take up the thrown thread loops. The one in question the auxiliary device carrying and driving the double-edge bar contains an oscillating shaft 450 (Figs. I, 2, 13 and 20) which extend along the 'machine and love as well rearward of the Scliwitlgwelle 420 described above. Between each two fonts sits on the shaft 450 an upward lever arm .152, which at its upper End carries a support plate 154, which in a rearward position of the arms 354 and the double-edged bar 352 contacts adjustable stop screws 456 that are held by the Double-edged bar support arms 354 are carried (Feg. 1, 2 and 13). Also at the Oscillating shaft 45o are one or more that regulate the pressing of the double-edged liacs Cam levers 458 are provided, each of which, like that shown in Fig. 13, on the lower end is provided with a runner 46o which engages with each of the two Drive dry 462 and 464 of the double edge camshaft 362 is able to occur. the Rocker shaft 450 is used in a counterclockwise direction as viewed in FIG. 20 for abutment of the rotor 46o against its INTocken by means of the tension spring 466 influenced, the acts against a downwardly directed lever 468 attached to the swing shaft 450. An orbital movement of the oscillating shaft in the counterclockwise direction is caused by a forward stop arm 470, which carries a stop screw 471, which lies against the underside of the table 118.

The support plates that support and drive the double-edged bars Auxiliary device including 454 and arms 452 can also be used. at times any of the double-edged bars 352 with their support arms 354 in an outermost rearward one To hold the position in which the parts lying behind including the chair needles are more easily accessible to the operator for adjustment or replacement. For this purpose, each arm 452 carries a locking arm 469 which, after pushing backwards the double-edged bar in the desired out-of-the-way position by the operator can be pivoted upward into a horizontal position in which the Latches 469 engaging a cooperating screw 456 do any return movement the double-edged bar forward under (learn to prevent the influence of your tension ropes.

In accordance with a characteristic of the invention, the individual double-edged bars 352 are designed and arranged so that they can be easily removed from their support lever arms 354 to allow the operator easy access to the underlying parts of the riveter for repair and adjustment. The proposed locking device is so constructed and arranged that the double edge Barre with a high degree of accuracy 'returns to the desired operating position on the Doppelrandbarrentragarm 35.1, as shown in FIGS. 13 to 17 is recognizable. According to the embodiment shown in these figures, the double-edged bar extends substantially beyond the cover plate 353 at each end, so that a flat vertical surface is present at each end of the double-edged bar structure, which is an extension of the slotted surface of the double-edged bar and has opposite undercut inclined surfaces 472, which form a wedge fit with a vertical wall 473 and a cooperating inwardly sloping wall 474 of a double-edged bar receiving base provided on each of the double-edged bar supporting arms 354. A transverse pin 475 reaching over a lower part of the base engages in an oversized square catch 476 which is cut into the underside of the double-edged bar 352 (see, for example, FIGS. 14 to 16). The double rim bar is locked in place in the socket at each end by means of a spring loaded key pin 477 which fits into a correspondingly tapered bore 478 provided in each end of the double rim bar 352.

A helical compression spring 479 lying around the pin 477 and at one end against the wall of the base and at the other upper end against a ring 480 attached to the pin 477 strives to lock the pin into the tapered one located in the end of the double-edged bar Hole: press f78. At its outer end, the tapered locking pin 477 is equipped with a transverse pin 48i which, in an angular position of the pointed pin, engages in an axial slot 482 in the arm 354 carrying the double-edged bar. If it is desired to remove the double-edged bar from the machine, the locking pins 477 are pulled out at each end and rotated 90 ° so that the transverse pins 481, thus pulled out of the slots 482, cross over to the slots and accordingly hold the locking pins 477 in a retracted position, which is the position in phantom in FIG. From these figures it is easy to see that the tapered locking pin, as soon as it is released by the alignment of the transverse pin 481 with its groove, is pressed by the spring 479 against the lower side of the tapered bore 478 in the double-edged bar 352, around the double-edged bar downwards so that the vertical flat front surface and the cooperating sloping back surface of the double-edged bar are firmly gripped by the cooperating flat and inclined surfaces of the base to hold the double-edged bar very firmly in the desired working position. At the same time, the expansion pressure of the spring 479 tends to move the support arm 354 and base longitudinally away from the end of the double-edged bar so that the transverse pin 475 is firmly pressed against the side of the detent 476 cooperating with the pin.

Next is according to the invention a new improved device for precise alignment of every single double-edged bar with the needles and the cooperating ones Knitting tools of the associated font for the purpose of performing the stop and double edging work provided. The improved alignment device shown here of the individual double-edged bars contains an upwardly directed fin 483, which sits in the middle of the double-edged bar (Fig. 1, 2, 9 and 13) and which is when moving forward the double-edged bar in the working position with reference to the chair needles between two Stop screws 484 taken by the upwardly facing arms of a console 485 of the shaft 253 r; holding the edged needle bar 252. This arrangement, in which the double edge bars with respect to the needles through one in the middle of the Double edge bar lying device are aligned, has the advantage of large Simplicity. Difficulties arising from the expansion or contraction of the double-sided bar or the associated parts are avoided, and every possible error, that from such an expansion or contraction of the double-edged bar with reference on the \ reprobable bar is reduced, since in each case only one small section of each bar in, is affected.

The double edge camshaft 362 of the illustrated machine is intermittent from the main camshaft i2o by one that only acts during one revolution Clutch driven, which is switched on during the stop, to the double-edged camshaft 362 through one revolution, and then again during the double edge transfer or the push-up process is switched on to the double-edge camshaft turn it a second turn. As detailed below, if the double edge camshaft is offset to the left from a neutral position, around the group of cams used when hitting in the working position for creating l-l the row of cast-on stitches and will then move out of the neutral position shifted to the right to the group of the transferring the double edge effect Cam for the purpose of carrying out the double-edge transfer or pushing-on process in the working position bring to.

The device for driving the double edge camshaft 362 from the Main camshaft i2o (Figs. 8 and 18-20) includes a chain 486 that has a sprocket 487 splinted onto the main camshaft i2o and via a sprocket on the Double-edged camshaft 362 for the purpose of rotation loosely ripped sprocket 488 is running. The bushing hub of the sprocket 488 is against axial movement with the double edge camshaft 362 secured by the engagement of a runner, which is secured by a part forming a wedge a console 489 is carried which is screwed to the underside of the work table 118 and is able to enter a groove 490 in the hub sleeve of the sprocket 488. A surface of the hub portion of the sprocket 488 is used as the single-tooth drive element 491 formed a coupling driving the double edge camshaft, which is connected to a corresponding detent is able to engage in a driven coupling sleeve 492, which is keyed onto the double-edged camshaft 362 for rotation and can move axially with respect to this shaft.

The operation of the clutch driving the double edged camshaft is controlled from the machine's pattern assembly through links which include a clutch slide fork 494 which, as seen in Figure 19, has two arms extending upwardly from a hub sleeve. The hub sleeve is carried by a transverse pivot shaft 496 which is supported in a hanging bracket bolted to the underside of the work table 118. The Gabe1494 is equipped with jaws 5oo which engage in a circumferential groove 502 located in the driven coupling sleeve 492. Two laterally directed lever arms 504 and 506 sit on the hub of the clutch shifting hub 1494 at one end of the hub, and a lever 507 extends from the central portion of the fork hub. A tension spring 5o8 connected between the arm 5o4 and a downwardly directed portion 51o of the console 498 tends to keep the fork 494 and the driven clutch hub 492 out of engagement with the driving clutch 49o. A stop screw 512 seated in a catch on arm 506 can come into contact with part of the bracket 498 in order to limit the movement of the sliding fork and the driven coupling element 492 taking place under the influence of spring 508.

In order to rotate the double-edge camshaft 362 back and to bring it into the same radial position after the completion of each successive rotation, a notch 514 cut into the peripheral surface of the driven coupling sleeve 492 engages a roller 516 which is carried by a locking arm 518, which is swingable is mounted on console 498 at 52o. The roller 516 and the locking arm 518 are urged into contact finite the detent by a tension spring 522 which acts on an extension of the locking arm5i8. The coupling element 492 is drivingly shifted to the right into its inoperative position at the end of a revolution, so that the locking roller 5i6 comes to work in order to stop the double edge cam in the desired predetermined U'iiikelposition by means of a decoupling device, which has a cam 524, the one on the right Surface of the driven clutch pulley 49z is provided and includes a cooperating roller 526 carried by the lever arm 507 attached to the fork hub. As soon as the driven coupling part 492 approaches the end of one revolution, the cam 5z4 contacts the roller 526 and presses the roller 526 and arm 507 downward in order to drive the driven coupling sleeve into its deployed position shown in FIG. 8.

The pattern controller for sliding the double edge camshaft clutch in its drive position contains a downward 1, eillcer 53o, which with its upper end on the fork arm 5o6 and with its lower end on an AI-111 532 (Figs. 8 and 18) is attached, which sits at one end of a pivot pin 534, the console mounted on the lower front rail 116 of the machine 536 stores. The Söhwingzapfen 534 carries a Von on its opposite end one: sample bar controlled lever that has an upward arm 538, which is supported against a ring 54o which sits loosely on a sample rod 542 and resiliently against a compression spring 544 and one split on the sample rod 542 Retaining ring 546 lies. An oscillating movement of the oscillating pin 534 and its associated # n Causes parts clockwise from the position shown in Fig. 8, that the double edge camshaft coupling is moved into its coupling position. A Latch, which consists of a spring-loaded tooth 548, which is inserted into the on the underside the hub bushing formed by arm 538 is able to enter the cam notch 549, serves to this, the pivot pin 534 and its associated parts in that position to hold, which corresponds to the engaged position of the clutch.

The device for displacement of the Doppelrandnockenwelle362 to the left to bring the double edge stop cam in the working position, and then, includes, to the right to bring the double edge transmission cam in the working position, as seen from FIGS. I and 8 best seen, two cams 550 and 552 which sit at a distance from one another on the double-edge camshaft 362 and have grooves on their opposing surfaces for the engagement of a rotor 554 which is carried by a lever 556 rotatably open on a pivot 558 for moving the double-edge camshaft. A tension spring 56o tends to swing the slide lever 556 and the runner 554 inwardly against the axis of the double-edge camshaft. The cam grooves provided between the disks 550 and 552 consist of an outer, neutral cam groove 562, which usually holds the double-edged camshaft in its neutral intermediate position, of a cam groove 564 used when striking the double-edged goods, which works when the sliding armature is moved inward to move the double edge camshaft to the left, and from a cam groove 566 used in the double edge transfer, which then works as soon as the slide rotor 554 is moved further inward to move the double edge camshaft 362 from its neutral intermediate position to the right. At the end of one revolution of the double-edged camshaft for each bump and bump action, slide slide 554 and slide lever 556 are moved outwardly to their neutral position to align slide 554 with the neutral cam groove. This outward movement occurs as a result of a runner 568 running up against a cam surface 570 which cooperates with the runner and which is seated on the cam disk 552.

The inward movement of the slide cam 556 from the neutral position to the double edge stop and push position is controlled by a downwardly directed latch lever 572 which is secured to the pivot pin 558 to rotate with the slide lever 556 (Fig. I). The locking lever 572 has at its lower end three notches labeled A, B and C, which work alternately with a locking surface 574 which is formed in a horizontal arm of a locking lever 576 which is arranged in the lateral direction and loosely on the rotary shaft 36o. A tension spring 578 connected between the locking lever 576 and an arm provided on the hub of the locking lever 572 endeavors to keep the locking lever and the bolt in engagement with one another. The operation of the locking lever 576 is controlled by links which include a downwardly directed link 58o which is connected at its upper end to the locking lever 576 and at its lower end finitely to an arm of a bell crank 582 (Figures 1 and e) which is swingable is mounted on a bracket 584 mounted on the lower front rail 116 of the machine. An upwardly directed second arm of the bell crank 582 contacts a ring 586 which is splinted onto a sample rod 588.

According to the invention, an auxiliary device is provided to insert the double-edge camshaft coupling and to move the double-edge camshaft into each of its working positions, namely the device includes an auxiliary cam on the main camshaft 12o of the machine and pattern-controlled rotor connections. The working of the auxiliary device is triggered by switching the pattern chain 309 of the machine, which takes place in the cycle that precedes the active movements of the 1N machine. The auxiliary cam-controlled slider in question, best seen in Figures 8 and 18, includes an auxiliary cam operated from a sample bar. Shifting lever 59o, which is mounted between its ends on a stationary pivot pin 592 and is equipped at its rear end with a pin 594, by which a runner 596 is carried, which is laterally displaceable for engagement with an auxiliary shifting cam 598 used when striking or with one of the Double edge transmission used Bilfsverschiebocken 6oo on the main camshaft 120 is. At its front end, the sliding lever 59o is equipped with a diagonally lying cam groove 602 , in which the rotor pin of a sliding ring 604, which sits loosely on the sliding rod 588 intended for the double-edge offset device, and also the rotor pin of a sliding ring 6o6, which firmly engages the sample rod 542 which actuates the double camshaft clutch is seated. The slide ring 60 cooperates with a Ritig 608 which is splinted onto the slide rod 588 associated with the double edge offset camshaft, these rings being separated from one another in order to introduce a delay in the movement of the camshaft offset device. A shift fork 61o, which sits on a sample rod 612 actuated by the sample chain and engages at its end in the grooved hub of the slide rotor 596, forms the means, controlled by the sample device of the machine, for the operation of the engagement of the double-edged camshaft drive clutch and the offset of the double-edged camshaft to initiate one or the other of their working positions: The work of the above-described device for moving and rotating the double-edge camshaft by one revolution for each of the double-edge stop and double-edge pushing processes is briefly as follows: During the machine train immediately preceding the formation of the stop mesh area, one moves Button of the pattern chain the pattern rod 612 to the right (FIGS. 8 and 18), whereby the cam follower 596 is moved onto the cam 598 which causes the impact. The tip of the cam 598 acts at the beginning of the couling of the intermediate stitch row or the cast-on row of stitches to set the lever 59o in an intermediate position. The rotor pin ring 6o6, which is attached to the sample rod 5d2 intended for the double-edge camshaft clutch, is immediately moved to the right, whereby the spring 544 is tensioned, so that the coupling part 492, which allows only one rotation, engages with the driving coupling part 491 as soon as the single tooth of the driving element comes into engagement with the corresponding detent in the driven coupling part. At the same time, the trunnion ring 604 is moved to the right on the shift rod 588 intended for the double edge camshaft offset and, after a time delay, contacts the ring 6o8 to move the double edge camshaft offset shift rod 588 to the right. As a result of this movement of the switching rod 588, which is effected by the angle lever 582 and the handlebar 58o, the locking lever 576 is pressed down sufficiently so that the tooth 57.4 moves from detent A to detent B. Shift lever 556 and runner 554 now move inwardly into engagement with the cam groove 564 intended for striking, as a result of which the double-edged camshaft 362 is shifted to the left into the position for striking the lashing bracket.

At the end of one revolution of the camshaft it becomes the double-edged camshaft returned to its neutral position and is driven by its drive mechanism switched off in the following `` '' mode: The: @ usternockenwellenschaltliebel 59o, due to the movement of its rotor on a deep part of the switch cam 598 works, causes the double edge camshaft clutch actuating Shift rod 542 returned to the left in its rest position assumed to Allfang will. The shift rod 612 moves to the left again into the position it was initially occupied Working position as soon as the pattern chain is switched, so that the rotor 596 in its rest position is lost. The cam 57o acting on rotor 568 has the effect of claß the double edge camshaft rotor 554 and the shift lever 556 outwards are returned into engagement finite the neutral cam groove 56z, so the DoppelrandnockenNvelle 362 resumes its neutral position. The cam 52I acts on rotor 526 to swing the clutch fork 4o4 and the clutch 492 to be interpreted. The rotor 516, which falls into a detent in the coupling part; I92, holds the double edge camshaft in its normal angular position, as it is for example in Figs. t and 8 is shown.

As can be seen from FIGS. 1, 2, 22 and 25 of the drawings, two rearward-facing bridges 620 are provided on each fontur, which are attached to the table and form the guide and carrier for the double-edged bar trigger hook structure. Two endless haul-off chains 624 are provided close to the bridges, on which double-edged haul-off hooks 626 sit. The pull-off chains 62, 4 run around guide disks 628, which are rotatably seated on Kon-zrolcu 632, which are attached to the underside of the bridges 6 = o at the ends next to the needles. The haul-off chains 624 extend closely parallel to the bridges 620 forwards, revolve around guide pulleys 63.4 which are loosely rotatable on a support shaft 636, and then descend and forwards to the drive and tensioning haul-off sprockets 638 on the thread haul-off shaft 64o. With their chain run turned away, the haul-off chains 62d are guided over guide rollers 642 and 644 and then return to the above-mentioned 1, ührun, rsselieibe 628. As can be seen from Fig. 25! the rollers 642 are mounted on lever arms 645 which are swingably supported by journals 646. Eitie spring attached to a downwardly directed hook 65o on _i: clerii lever arm 645, the other end of which is anchored to the underside of the machine table ii 8, endeavors to urge each roller 642 against the chain 624 in order to keep every slope of the chain dyke .

Zv, ei ati In the pull-off chain 624 forward of the double edge grasping Hook 626 attached cross rails 652 and 653, the end parts of which touch the bridges 62o, serve to hold the hooks 626 in alignment and in the desired plane.

A deduction parinuug is given to the various double-edged bar deduction chains 624 by means of a conventional weight load, not shown, and a cable pull 654 given, which is attached to a disc 656 that is located on your right End of the goods take-off shaft 64o (Fig. 22 and 25) is seated. To be light and sensitive Withdrawal tension for the individual pairs of chains and hooks with reference to the straight chain Maintaining pieces of goods knitted on the various fonts is one thing compliant connection between each drive sprocket 638 and the take-off shaft 640, by which the sprocket is carried, is provided.

According to the invention, the machine is equipped with a device that is made to work by a dummy movement of the lower machine and the edge needle bar to bring a double edge rod carried by the edge needle bar into such a position that it can be gripped by the double edge rod trigger hook and then to the double edge rod trigger to switch to drive so that the double-edged bars located therein are detected so that the double-edged goods are pulled off. The double edge bar haul-off chains 624 and hooks 626 are held in a predetermined position against the tension of the weight-loaded goods haul-off shaft 640 by means of bolts 670 , which are carried by pivot pins 672 lying on the inside of the associated bridges 620 and are equipped with stops 674, which are in front of the further after Take hold of the rear cross rail 652.

An end piece 68o of the bolt is provided to rest against a portion of a support bracket 682 and thereby limit the clockwise upward movement of the bolt. Each bolt is provided at its rear end with an upwardly offset part 684, which is touched by the double-edged rod mounted in the holder on the edging needle bar during the dummy plunge movement of the lowering machine, in order to move the bolt downwards and thereby the pull-off chains 624 and the hook 626 of the latch while the double-edged bar is moved into its engagement position with the hooks. After the hooks 626 have grasped the double-edged bars in this process shown in FIGS. 26 and 3o, the subsequent upward movement of the lowering machine and the edging needle bar with the holders pushes the double-edged bars out of the holders, so that in this way the transfer of the double-edged bars from the holders into the hooks and into the working position is finished.

Furthermore, according to the invention, a device is provided which, as soon as the double-edged rod pull-off chains 624 and hooks626 have been brought into the dot-dash position according to FIG. 5 by the pulling movement, works automatically to interrupt a further withdrawal of the hooks and automatically the hooks in the reverse direction to the predetermined position of FIG. 26 described above. The reset or readjustment device (FIGS. 21, 22 and 25) contains a reset pawl 686 and a ratchet wheel 688 which cooperates therewith and which is fastened on the goods take-off shaft 64o. The pawl 686 sits on the free arm of a continuously oscillating cam lever 69o, which sits loosely on shaft 131 for rotation and has a cam follower 692 at its rear end which engages a cam on the main camshaft 12o of the machine. A tension spring 694 attached at one end to a downward extension of the reset pawl 686 and anchored at its other end to the cam lever tends to keep the pawl 686 in engagement with the ratchet 688. A locking pawl 696 (FIG. 21) is rotatably mounted essentially parallel to the return pawl on a fixed bracket 698 and is resiliently held in engagement with the ratchet wheel 688 by a tension spring 700. The reset pawl 686 and the locking pawl 696 are usually held in the rest position out of engagement with the ratchet wheel 6-88 against the pressure of their associated springs by a shielding lever 704 which is pivotably mounted on the support shaft 636. The shield lever 704 is bifurcated at its lower end to provide two shield members, one on either side of the ratchet 688 for engaging under the edges of the associated return and locking pawls, as shown in FIGS. 21 and 25. The shielding lever 7o4 also has, as one-piece parts, a latch arm 7o8 and a locking arm 710. A tension spring 712, which is fastened at one end to the arm 708 and at its other end to a fixed part of the machine, tends to act as the shielding lever and to swing its associated parts clockwise to the position shown in FIG Stop 716 seated on the machine frame is limited. At the beginning of the production of a stocking, the shielding lever 1704 is placed in the position shown in FIG. 25, in which the reset pawl 686 and the locking pawl 696 are out of operation. When the working has progressed to a point at which the hooks 626 receiving the double edge assume the position shown in phantom in FIG. so that the reciprocating reset pawl 686 and latch pawl 696 are brought into engagement with the ratchet 688 to provide an incremental reset to the double-edged bar hooks 626 and chains 624. The shielding pawl 704 is held in this rest position during the entire period in which the double edge rod hooks and the chains are reset by a pawl lever 718 which is carried by a fixed pin 720 and has a hook-shaped outer end for the purpose of engagement with the locking arm 710 of the shielding lever 704 . A tension spring 722, which is connected between the pawl lifters 1718 and a fixed support on the machine, tends to pull the pawl 718 into engagement with the locking arm 710. A second arm 724 of the ratchet lever 718 is arranged to be contacted by a cross bar 726 overlying the rearward portions of the chains 624 as soon as the chains 624 and hooks 626 have been moved in the reverse direction to their starting position, around the ratchet lever 718 and thereby allowing the shield lever 704 to move clockwise under the influence of the spring 712 to bring the reset pawl 686 and latch pawl 696 out of action.

According to another characteristic of the invention, the machine is provided with a device for severing the jammed starting end of the double edge thread shortly after the double edge has been produced. The thread cutter designed according to the invention consists of a swingable knife arm 73o, which is rotatably held on a pivot 732 on the rail 62o on the left of each needle contour or job. A torsion spring 734 wound around the pivot pin 732, which is in engagement at one end with the knife arm and anchored at its other end to a stationary part of the machine, tends to move the knife counterclockwise, for example into the position shown in FIG to swing in which the knife acts against a fixed surface 736 to cut a thread leading from the supply to the first knitted course. So that the thread is correctly laid with respect to the knife surfaces, an upwardly directed thread guide 738 sits on the left-hand bridge at the rear end of the same, which extends the thread backwards from the usual clamp 739 to the thread guide (Fig. 22) , catches and stores properly. The swingable knife arm 730 is held in a raised position against the pressure of its spring by a pawl arm 740 mounted on a pivot pin 742, which engages behind a detent 744 in the hub of the knife arm 730 and is held in its locking position by a torsion spring 746. To switch these parts, a return arm 748 is provided in one piece with the knife arm 730 , which is arranged in such a way that it is gripped by a lateral catch 750 which consists of one piece with the hook 626 assigned to each fontur. The knife locking arm 74o is similarly equipped with an upwardly directed latch arm 752 which lies in the path of movement of the transverse rail 652 located further back.

The knife is controlled by a return movement of the double-edged haul-off chains 624 and necks 626 from the reset position, which has the effect that the transverse rail 652 located further back comes into contact with the latch arm 752 in order to lift the bolt 74o so that (The knife moves downward to cut the thread. This is the position of the parts shown in Fig. 28. This additional distance of backward movement of the chains 624 and hooks 626 to lower the knife is achieved by the action of the double edging relaxation device of the The machine is triggered and takes place during the production of the chain stitches. The reverse movement of the chains 624 and the double-edged bar 626 in the forward direction occurs when the file assumes the position shown in FIG the lateral catch 75o on the adjacent hook 626 detects the return arm 748 associated with the knife 730 in order to Return the knife to its starting position, in which it is held again by the pawl 740. It can be seen that a special knife is assigned to each fontur of the machine and that the double-edged bar pull relaxation device works as described above, so that all knives along the entire length of the machine simultaneously cut through the clamped ends of the double-edged threads at the various fonts.

The backward movement of the double-edged bar haul-off chains 624 and hooks 626 described above for operating the knife is caused by the same device that is used to release the tension on the knitted fabric. This device, which is best seen in Figures 7 and 12 of the drawings, includes a release pawl 758 and a ratchet 76o on the vare take-off shaft 64o. The trigger pawl 758 is swingably mounted on an arm of a cam-operated lever 762, which is mounted loosely rotatably on shaft i3 i. A tension spring 764 engaging pawl 758 tends to urge pawl 758 against (read ratchet wheel and against an adjustable stop screw 766 on cam lever arm 762. A downward extension of cam lever 762 carries a pin 768 on which a cam follower 770 is slidably supported which is displaceable to the right in engagement with a thread trimmer 772 and, when moved further to the right, in engagement with a relaxation cam or tension relief cam 774, in order to release the tension during the transmission process. A tension relief cam 776 is also provided on the main camshaft 120, which is brought by displacement of the main camshaft 120 in minder position to work, the trigger voltage during a reducing process set aside. the cam follower 770 is in its position for Ruflieben voltage during Aufstoßvorganges and to insert the thread cutting device in the working position by a Mus controlled device, which is operated by the pattern chain switching rod 778 and a sliding fork 779 ei '(-hold, which engages in a grooved hub sleeve of the cam follower 77o. As can be seen from FIG. 7, the cam lever 762 is also provided with a laterally directed arm 780 , which carries a stop screw 782 which rests against the double-edged camshaft 362 in order to control the clockwise movement of the cam lever 762 and its associated parts limit, as can be seen in FIG. 7.

The way the machine works to work the double edge part of a fully formed stocking blanks, which allow the putting on, the pulling off, the Folding and closing the double edge uniform is described below.

The finishing of the machine at the beginning of the creation of the double border requires two backlashes before you cast the cast on row. 111 the first Idle gear, in which the little horse runs from left to right, causes the to shift Pattern chain, which is made in the knitting cycle of 24o to 300 ° rotation of the main camshaft the zero position and takes place shortly after the distribution boards have been moved, that the shift rod 157 moves to the right (Fig. io and 5), whereby spring 1.58 is clamped and the shift fork j.56 the special control cam follower Attempts to bring 153 into alignment with the special stop control cam 152. The shift rod 157 is in the shifted position during two machine gears held.

The following operations take place in the second idle cycle, in which the kulating takes place from right to left: The special control cam follower 153, displaced by its spring 158, comes to rest opposite a deep part of the special control cam 152 and aligns itself with this cam; the switching rod 272 moves to the right, so that the sliding fork 323 and the needle press cam follower 133 move to the right on the stop needle press cam 136 (Fig. 10 and 3); spring 335 urges slide fork 334 and main control cam follower 144 (FIGS. 10 and 6) to move to the right out of alignment with main control cam 145; the sliding fork 271 and the cam follower 270 (Fig. 10 and 5) causing the high lift of the shortening machine moves into alignment with the high lift cam 273, and the sliding fork 324 (Fig. 12) and the cam follower 3o2 laterally displacing the edging needle bar moves to the right in its rest position. The switching rod 612 moves to the right in order to align the auxiliary rotor 596 with the auxiliary cam 598 used when it hits (FIGS. 8 and 18).

The sample shift rod 778 (Figs. 7 and 12) moves to the right, whereby shift fork 779 and tension release cam follower 77o are in alignment be moved with the thread trimming trigger cam 772.

The machine will stop and the double-edged thread guide will return to normal Way connected with its friction drive.

The following operations take place in the row of cast-on stitches: The auxiliary cam 598 acts directly to move the cam lever 59o to an intermediate position to swing; the shift rod 542 is moved to the right, causing the spring 544 is tensioned so that the coupling part 492 executing only one revolution in Engagement with the drive coupling part i1491; the shift rod 588 is after a short time delay moved in the same way to the right, whereby the ratchet lever 576 (Fig. I) is moved downwards into engagement finite cam B of the ratchet tooth g72, so the sliding runner 554 d @ ate inwardly into the position corresponding to the stop Position is moved to the double ratid camshaft 362 to the left in the stopping position to move the corresponding position.

Since both the main control rotor i44 and the special. When the control rotor 153 that works when it hits it is aligned with the respective cams (Fig. lo) and since the spring 335 belonging to the main control rotor 144 is tensioned to the right by the previous movement of the switching element 272, the main controller moves into the non-working position, and the special 1-cell rotor 153 takes over the regulation of the stitch length in the stitch row.

The pattern chain 309 switches and releases the switching rod 272, the can return to their non-working position as soon as (read through working of the runner is allowed.

The press cam follower 133 remains in its shifted position until the pressure is removed from the runner 133 by the takeover of the main regulator in the next course of stitches.

The 1-fusterschalterstange 94 (Fig. 3 and io) shifts to the right, so claß the sliding fork 95 and the mediating the vertical needle stroke movement Cam follower 92 aligns itself with the particular, vertical movement move mediating cam 9i when striking. This shifting takes place at approximately 27o ° of the revolution of the camshaft in the stop stitch row takes place.

After the particular regulator has worked to get the needles for the Set the thread distribution process correctly, and as soon as the needles are in when they are cast on required pressing position are moved, a slightly higher tip of the swings special control cam the control shaft far enough to apply the pressure on the skin pt rule cam follower 144, which is then allowed to go on a small cam descent to run and left to his normal working position under the pressure of the usual Return spring for shift rod 272 to move. Immediately afterwards the special one can Normal rotor 153 to the left into its normal non-working position under the influence the usual return spring for shift rod 157 return.

The working method of the knitting tools and those that work with them Double-edged linen during the production of the row of sling stitches is connected with the schematic representations of FIGS. 39 to 53 as follows: 39 shows the relative positions of the needles, sinkers and knockdown chains in the normal Starting position for zero degrees rotation of the main camshaft. The needles are there in the highest position, and di @ sinkers are withdrawn, in front of the one from the left passing the thread guide and the steed to the right. The relative positions of the cooperating knitting and double edge tools in each of the figures mentioned is in degrees of motion for successive angular positions of the camshaft the Camshaft specified from the zero position \ vorcu. In this connection it should be mentioned that although the double edge cam shaft in one i: i-Vc @ hü @ tnis finite the main camshaft revolves, the l) olihelran (luocl <ent @ -elle for the purpose of rotation with the Ilaill) tnocl: ciiNvelle is only coupled when the main curl do 6o ° has turned. The rotation of the I> oppelrand camshaft is then during of the first section of the next cycle of action.

_ltis the zero position shown in Fig.3p takes place Thread feeding and patting. (read the script of the double-edged thread guide and of the lollipop from left to right and the constant advance of the distribution plates for the distribution of the meshes so that the loops of the loops against the shafts all needles. This is the position shown in FIG. During this "The guide space between 77 and 100 ° rotation of the main camshaft becomes the double-edge camshaft verachoben to the left of the position shown in FIG. 13, uni the Strike 1) e \\ irkenderi cam 430 with the runner 428 of the \ 'orriclitung for horizontal Movement, furthermore the cams 396 and 398 with the runner 39-1 of the device for vertical movement and finally the press cam .I6: 1 with the runner 46o the Align double ratid ingot strengthening device.

Between 145 and 100 ° rotation of the main camshaft, the double-edge hooks are moved in an arc from the position shown for example in FIGS. 1 and 2 to the position shown in FIG. 4o, in which they lie directly above the needles. During the subsequent operation of the machine, the double edge hooks continue to move backwards and then downwards onto the hook side of the needles, with the position of the various cooperating tools at 251 ° rotation of the main camshaft in _F, 11-. 41 is shown. As can be seen in Fig. 42 at 26o ° rotation of the main camshaft, both the double edge hooks and the chair needles move downwards against the apex of the sinker plates and distribution plates. Immediately after the sinkers have been fully advanced, the double edge hooks move down below the sinker apex planes and are held in alignment with the second needles by these sinkers.

When the main camshaft rotates 271 ° (Fig. 13), the special nadelpreßnocken 136 (Fig. 3 and 1o) control the needles, whereby it your special start-up mesh length control unit 153 is made possible in its non-working position and the main control cam follower 144 is allowed to return to its Cam 1:15 to come into alignment. At this point the double-edged hook bar becomes solidified and made more rigid by the washer plate .154 that holds the screws .156 of the double edge bar arms 354 touch. The horizontal movement of the double edge hook bar generating cam 43o extends from about 273 ° radially, and the Doppelrandpreßunterlageocken runs in the same way radially from 271 to 31o °, so that the double edge hooks Move vertically downwards with the screws 456 in contact with the washers 45d are. In the position according to FIG. 45 at a rotation of 281 °, the tip of the needle press cams is located 136 immediately below your runner 133, whereby all other needles of the needle row be caused to press the needle beacons against the double edge hook, so that the continued downward movement of the needles causes these intermediate needles throw off the loops they hold. In Fig. I6 lead at 294 ° rotation the double-edged liacs continue their downward movement, the sinkers are in retracting the sinker head as in normal knitting and moving the needles downwards and away from the nip, under the influence of the stop pin press cam 136. The plates 454 stiffening the double-edged bar continue to guide the be - \\ unique double-edge hooks that follow the outward movement of the needles move something forward. As can be seen from FIG. 47, at 310 ° rotation the, as explained above, thrown thread loops every second needle over the Noses of the still retracting sinkers stretched. At 312 ° (Fig. 48) has the continued forward and downward movement of the double edge hooks causes the thread loops to the noses of the sinkers (learn to leave the same point in time, where the front parts of the double edge hook touch these thread loops and in pull in a forward direction. The double edge hooks hold a little tension the thread loops upright during the period of time during which the double-edged liacs cross the line of the heads of the needles. At 32o or 323 ° (Fig. 49 or Fig. 50) the double edge hooks on the front of the needles by the needle press cam 136, which has a very steep ascent immediately after 310 °, around the Set hook for a plunge movement to take up the squeezed thread loops. At 328 or 335 ° (Fig. 51 or 52) the vertical position of the double edge hook remains fixed, and the double edge hooks move under the influence of the usual double edge hooks Trigger tensioner forward away from the needles. By a narrow margin between the lower edge of the double edge hooks and the tips of the needles for the in To maintain the positions shown in Figs. 47 and 48, the has the vertical Movement of the double edge bars when striking the cam 396 an adjustable Segment 81o. as can be seen in FIGS. 13 and 33.

It is recognizable that the increase of the exhaust support of the double edge Barre causing the cam 462 is steeper than the corresponding descent of the inputs and Ausbewegung effecting DoppelrandnOc ken .I30 so that the erkenntliche particularly in Fig. 7 nacligiebigeVerbindungzwischen demNockenläuferliebel .126 and the swing shaft 420 carrying the double edge bar comes to work to hold the double edge hooks against the stiffening plates 454 under a relatively strong spring pressure.

As can be seen from FIGS. 5o and 52, the double-edge hooks from 323 ' stand up until they are later lifted again to form a fold in the double-edged goods by means of the double-edged rod, vertically and protrude about 1.5 mm below the upper edge of the knock-off combs. Movement of the double-edged hooks to their deepest position under the influence of the vertical stroke effecting cam 398 enables the locking lever 374- (Fig. 2) to move over the pawl lever 376; which is attached to the swing shaft 36o causing the vertical movement of the double edge hooks so that the pawl 376 contacts the lower step of the detented end face of the locking lever 374.

After about 5 cm of the double edge fabric has been knitted, the position of the double edge hooks is adjusted in the vertical direction, partly to create space for the movement of the double edge rods underneath, and partly to compensate for the increase in size of the downward movement of the double edge hooks. which swing on their arms 354 around the rotary connection with support arms. To this end, the shift rod 390 (Figs. 2 and 9) moves sufficiently far to the right to bring the runner 382 to the right in alignment with cam 384, which causes the locking lever 374 to swing enough so that the pawl lever 376 opens the upper. or outer step of the detent-provided lower end of the locking lever 374 touches down. In preparation for inserting the double-edged rod, the lowering machine is also automatically moved downwards from its high, non-working position. Switching rod 279 (Fig. 5 and io) and lug 278 are moved to the right due to the switching of the pattern chain and move the sliding fork 271 and the high-lift cam follower 27o to the right in alignment with the high-lift cam 273. At the same time, this is also from the pattern chain The controlled shift rod 284 moves to the right and biases the spring 286 which, when the load on the pawl 280 is released, acts to bring the pawl 28o out of alignment with the pedal 265. The operator now turns the various edged needle bars 252 downward into the working position, so that the double edge bars held in the holders of the edge needle bars are in the position for inserting the double edge bar.

The machine is preferably set up so that it is now at reduced Speed works.

The process of inserting the double edge rod is now carried out by the Usual reduced regulation activated by the sample chain (not shown) initiated, which comes into action to move the main camshaft to the right in the usual reduced position to move. Since the device for lateral displacement of the edged needle bar, is disengaged as described above, only a dummy reduction process is carried out, by means of which the double edge bars and their holders, as shown in Fig. 3o, be brought downwards to the double edge rods in the path of movement of the Bring double edge stripping hooks 626 and engage the hooks with the rods to push. The ratchet arms 68q., Pressed down by the double edge bars release the double-edged trigger hooks 626, which then grasp the double-edged rods and push them against the goods.

As can be seen from FIGS. 6 and 12, the extreme downward movement of the reducer frame during the dummy reducer movement is accompanied by an oscillating movement of the cam lever 255 which moves the reducer vertically. The front extension 329 of this lever lifts the pawl 326 so that the runner 302, which mediates the lateral displacement of the edging needle bar, can return to its working position.

The forward movement of the haul-off chains 62; and the double-edged hook 626 for engaging the double-edged bar and for tensioning the double-edged bar (FIGS. 28 to 3o) causes the laterally extending lug 75o on the adjacent hook 626 assigned to the knife arm 730 to return the knife arm to its starting position, in which it is held again by the pawl 740.

As soon as half of the double edge has been worked, the Mining machine in the usual way in action to be under control by the pattern chain to form the edge by means of the edge rake 252.

The transfer of the start stitch row back to the needles for closing the double edge is completely automatic and is controlled by the machine's pattern chain. The machine is set for slow gear. In the row of stitches immediately preceding the transfer, a button on the pattern chain moves the pattern switch rod 279, stop 278, shift fork 27i and the cam follower 27o causing the high lift of the lower machine to the right in alignment with the cam 273 for the high lift of the lower machine. The lower machine is then raised and is locked in its maximum position in order to avoid a possible interference with the double edge hook during the transfer process (Fig. Io). The shift rod 778 (FIGS. 7 and 12), shift fork 779 and tension release cam follower 770 are shifted to the extreme right in alignment with the cam 774 which is used to release the fabric tension. The contour of the cam 774 is such that the tension release lever 762 and pawl 758 acting on the ratchet wheel 76o release the tension on the fabric a little before the time when the double edge hooks begin their return movement over the needles and toward the hook side of the needles . The tension is only relieved for a limited time by the action of cams 774 to assist the double edge hooks as they move backward. The shift rod 612 (FIGS. 8 and 18) is shifted to the right by a sufficient distance to bring the auxiliary cam follower 596 into alignment with the auxiliary transmission cam 6oo.

At the beginning of the double-edge transfer, the auxiliary transfer cam 6oo lifts the auxiliary cam lever 59o into its extreme upper position. The shift rod 542 associated with the double edge clutch is shifted to the right, thereby tensioning the spring 544 so that the double edge camshaft clutch 492 is brought into engagement with the driven coupling part 488 to drive the double edge camshaft 362 (FIGS. 8 and 18). After a short time delay, the shift rod 588 intended for the double edge camshaft offset is shifted to its extreme right position (FIGS. 8 and i), whereby the pawl lever 576 comes into engagement with the most downwardly lying step surface C of the locking lever 572 , so that the double edge camshaft sliding armature 554 by a maximum amount inwardly in contact with 'cam groove 566 is brought to move the double edge camshaft 365 to the right into its transmission position.

Urn a disturbance with the working of the double edge cams during the To avoid transmission, it is necessary to redesign the locking lever 374 (Fig. 2). For this purpose, the shift rod 39o is moved to the right as soon as the chain switches in the transmission time. whereby the sliding fork 388 and runner 382 slid to a rightmost position for engagement with cams 386. Immediately afterwards and before the double edge hooks begin their final upward movement, the locking lever 374 is clockwise to the extreme position shown in FIG Position led. A swing motion of the rotating shaft 36o and the ratchet lever 376 clockwise when moving the double edge hook into its upper position, that the pawl lever 376 lies against the side of the locking lever 374, what the in Fig. 2 is the final rest position shown.

The work of the knitting tools and the double edge hooks working together with them during the knitting of the double edge transfer stitch row is described in connection with the schematic views according to FIGS. 55 to 63. During this process, the double edge camshaft is shifted to the right, so that the Nocl: en4oo (Fig. 13) with rotor 394, which causes the up and down movement, and the Dnlaf> elrand transfer cam 132, which causes the back and forth movement, are in alignment with rotor A2S.

At sth: i i ho 'rotation of the main camshaft it touches the \' or- and backward movement, runner 428 has its cam, and the double edge hooks move slowly towards the needles. The atrf- ttiid downward position of the double edge hooks is cerebrated by the locking lever 374 (Fig. 2) to approximately 3o7 ° (_'mdreliung of the main camshaft when the rotor 394 intended for vertical movement is in contact comes with his cam 400. As shown in Fig. 55, at 3070 revolutions are approaching the camshaft, the knitting needles of a newly formed stitches before knocking off corresponding discount position. The boards are being withdrawn. The double edge hook move backwards towards the press, on a proportionate basis deep level where they still drink from the tops of the needles - @ 'tchen, so that the meshes held on the double edge hooks under the tabs of the sinkers step. At 3r8 ° rotation (Fig. 56) the needles start their downward and backward movement continue at the tee, the sinkers are pulled back even further, and the double-edge hooks are pressed firmly against the edge of the press under the resilient spring pressure that by the resilient connection between the cam lever 426 and the rocker shaft 420 is created. The double edge hooks are perpendicular in a proportionate way deep position in which the initial row of stitches is as deep as possible on the tops of the knock-off ridges in a position to accommodate the upward moving needles. With a rotation of 323 ° (Fig. 57) the upper end has or the head of the needle has the grooved front surface of the double-edged hook on its lower one Touched the end. The needle sliding in the grooved front surface of the double-edged hook moves up through the spread mesh. As in Fig. 58 and 59, the needles continue to rise while the double edge hooks move even deeper between the knock-off ridges in order to transfer the stitches to ease on the needles further. In Fig. 6o the double edge hooks have moved to its deepest position to make up the starting row of stitches to throw off their hook. Every second needle now has two loops of thread on it Shank below the tip of the hook. From the intermediate needles shown in the schematic Views are not specially represented, each only carries the one newly formed Mesh. 61 through 63 show the final stage of double edge transfer in which the double edge hooks on the hook side following the upward movement of the needles of the needles rise and then forward over the vertex of the needles move away into non-working position. As can be seen particularly from FIG. 62 the double edge hooks as soon as they come upwards free from the press edge, snapped backwards away from the needle hook under the influence of the tension, those in the above-mentioned flexible connection between the double-edged bars back and forth moving cam levers .f26 and (° r the double edge bars fore and - rocking shaft 420 causing the return movement. This effect was made by It was found to be of particular value to avoid possible accidental contact with the double edge hook with the needle hook and to prevent possible damage.

According to the preferred embodiment of the invention, the trigger the '' goods under the through the take-off shaft 6, .o generated tension continued until the double-edge hooks are shown in dash-dotted lines in FIG Assume the position shown, at which time the cross rail lying further forward 653 touches the pawl arm 7o8 of the shielding love 704 and swings around the reset pawl 686 and the latch pawl 696 to bring into engagement with the ratchet 688, so that then a gradual return movement of the double edge bar hooks 626 and chains 624 is granted. When the reset process is completed, the moves over the previous one Section of the chains 624 connected cross bar 726 to the arm 724 of the ratchet lever 718, which in turn enables the shielding lever 704, the reset pawl 686 and to move the latch pawl 696 out of the working position.

When the double edge rod trigger created by the double edge rod trigger hook 626 is no longer required for further work on the length and foot part, is generated the weight of the double edge bars per se and the weight of the goods hanging on them in connection with the product advance effect of the fluted knock-off combs described above a deduction that is sufficient during the knitting of the remaining part of the stocking blank is great.
