The present invention relates to improve,

ments in straight knitting. machines and more particularly to the yarn carrier controlling mechanism.

/Vith ordinary knitting machines it ispossible to knit plated angular or other designs as for instance by the means disclosed in the patent of /Verfelman and Strelz No. 1,601,545 of September 28, 1926.. Up to the present time however, no practical means has existed whereby it is possible to solidly knit such patterns or designs in the fabric itself automatically. The advantages of such solid knitting are many. For instance, the matrix or body color yarn portion of the fabric on which the plating is made in the known device is entirely eliminated with the fabric knitted by my new device, thereby firstly saving considerable quantities of the yarn and secondly", permitting the production of a solidly knitted design or pattern whereby either side of the fabric can be used.

An object of my invention is to provide improved and practical means whereby. a great variety of designs such as angular designs or other patterns can be solidly knitted into a fabric automatically; a

Another object of this invention is to so construct said means that the change from one pattern to another may be affected very readily.

A further obj ectis to provide means'whereby the stops which control the yarn carriers will be caused to automatically change their positions relative to themselves and to the yarn carriersto control the strokes of the yarn carriers according to the design carried.

Still another object is to provide a novel stop construction which will provide for a minimum loss of space due to the employ ment thereof Without reducing its effectiveness. 1 y v And still another object isto provide a comparatively simple construction which may easily and readily be applied to any'existing machine without materially changing the construction of the machine itself.

Yet another object is to provide a comparatively simple mechanism which may be manufactured at low cost.

Only'so much of the machine proper is shown as will be necessary fora full, and clear understanding of my invention. In the. drawings a denotes the usual oppositelyinclinedneedle beds in which rows of successively operated independent needles (not shown) are arranged transversely of and at opposite sides ofthe path of travel of the yarn carriers Z2, 6 b b b Guided O he miles f Saidbd i e s al ca denote corresp d n owing in "d e riage, 0 (shown only partly) which may be operated in well known manner either by hand or automatically and which is provided with the usual plungers cl, 0?, mounted on the front side thereof, and adapted in well known manner to operate the said yarn carriers. Similar plungers (not shown) are mounted at the rear side of said carriage.

The said carriage 0 by means ofsaid hand or automatic drive is given reciprocal motion on rails a over the needle bed a, in consequence, of which the yarncarriers move I to and fro in limited manner to be presently described.

Two yarn carrier bars 10 and 10', one in front and one in the rearof the needle bed and" arranged parallel to rails a thereof are providedand' on these bars the yarn carriers are slidably mounted as by means of frictional engagement or other means. 7 Suitably mounted on each of said yarn carriers andadapted to lie on the top surface of the respective bars 10and 10 in the path of travel of the plungers d is a catch mechanism which said plungers are adapted to engagein order to shift the said carriers. Each of said mechanisms comprises a block 11 which has a rectangular cut-out portion 11, intermediate its ends, and the ends 11 and 11 thereof are beveled as shown. Each plunger 7 d is spring actuated and the operating end thereof normallyte'nds to project below the top surface of said blocks 11. Therefore if the said plunger moves overthe said block the said end thereof will ride over the beveled ends 11? and. 11 of the block andfwhen' it reaches the cut-out portion 11" will slide therein and by abutting against an edgeof block is. adjustably mounted on the rail and is' provided also with bevelled ends 12 and 12 which lie in the path of travel of said plunger cl", whereby as the plunger carrying the stop block 11 of the said yarn carrier rides up onto one end 12 it releases the said block 11 and may continue its motion without the same. I

The motion of yarn carrier 5 is controlled by similar stop blocks 13 and'14 mounted to the rear of the bar 10 and which lie in the path of plunger 0?. Now then to limit the righthand motion of the carrier 6 it would I ordinarily be necessary tohave a stop similar to stop 12. However, to limitthe left hand movement of carrier 5 a stop block similar to stop 12 is necessary and as the said with each other the rear stop blocks 13 and 14 havetwings 15 and 16 respectively formed thereon which have the bevelled portions15' and 15 16 and 16 The said wings l5 and 16 lie in the path of travel of plunger cl which operates the carriers 5 and 6 Mounted on the front faces of said wings are stop pins 15 and 16 respectively against which the blocks 11 of carriers 6 and 5* may abut in extreme right and left hand positions. Thereby it will be noted thatthe separationbetween blocks 11 of yarn carriers b and b has been reduced to the width of the stop pm 15 In the present instance the stops 13 and 14 each have suitably connect'ed thereto respectively straps 13 and 14 are strapped together by suitable strapping means 17 (Fig. 6) in order that the said blocks may be controlled as a unit from the stop shifting mechanism now to be described. The said straps havepins 1.3 and 14 for. a purpose to be hereinafter specified.

'Mounted in front of said bar 10 on suitable supports 18 and 18 are two rods or bars '19 and 20 each bar being provided on Q its upper surface with a plurality of spaced holes or depressions 19 and 20, respective y A similar set of bars 21 and 22mounted at the rear of bar 10 on supports 23 are also 'respectively' Bar 19 of the front pair is for a purpose hereinafter to be specified.

adapted to be geared to bar 22 of the rear I.

pair by a gear 24 which is fixedly mounted on a shaft 25, which atits opposite end has mounted thereto agear 24, the gear 24 meshing withthe bar 19 of said front pair and the gear 24 meshing with the bar 22 of said rear pair 21. Y

Similarly gear 26 mounted on the front end of a shaft 27 meshes with the rack on the bar 20 of the front pair and a gear 26 mounted onsaid same shaft 27 meshes with the rack on the bar 21 of the rear pair. The said shafts 25 and 27 are rotatably journaled to a suitable mounting 28 in the frame of the machine. By this gearing arrangement motion imparted to either of the front pair of bars will be transmitted to the corresponding' bar of the rear pair.

In order to individuallymove each of the bars of the front pair in the present embodiment I prefer to use a ratchet mechanism for each of said bars of said pair and which is mounted near one end of the machine as for instance in the position'shown in Figs.

1 and2. The said ratchet mechanism for each of said two bars comprise plates 29 and 30 respectively, rotatably mounted on a shaft 31, said shaft being suitably journaled in the frame of the machine proper. Said plates 29 and 30 are each provided witlrtwo oppositely extending wings 29. and 30 respectively in which there are arranged slots 29am plate 29 and similar slots (not shown) in plate 30. FiXe'dly mounted on said shaft 31 are two laterally projecting arms 32 and 33' one for each of plates 29 and 30 andsaid arms are adapted to he at an angle with the wings 29. and 30. Pivotally-mounted to said arm 32 on a common pivot 32 are two pawls 32 and 32 which extend in opposite directions. A similar pair of pawls are identically mounted on arm 33. Said pawls may, engage the racks of said bars 19 and 20, pawls 32 and 32 being for bar 19 and the other pair of pa-wlson arm 38 for bar'20." One pawl of the latter pair is shown'in Fig. 5. Each of said pawls is provided with a pin 32*, 32 and 33 and 33 respectively which are adapted to lie in the respective slots 29 and the similar slots in plate 30 thereby controlling the engagement of the former with said racks 19 and 20 Suitably formed on the arms 32 and 33 are pins 32 3'2 and 33 and 33 respectively, and adapted to be stretched between thesaid pins and the pins on the pawls are coiled tensionsprings 34' which tend to always reduce the angle between the pawls and the arms 32 and 33. By the rotation of the plates 29 and 30 because of the engagement in the respective slots of thepins on the pawls, it is possible to' bring each of said pawls into or out of engagement with the respective racks of the bars 19 and 20. g p

In order to effect the rotation ofsaid plates 29 and 30 suitable cam means is employed. Mounted on rotatable rods 35 and35 respectively are two cams 36 and 37 respectively,

. cam 36 engaging plate 29 on the lower edge thereof and cam i 37 engaging plate 30 on w the lower edge thereof, so that when said cams are rotated transversely to the plane of said plates 29 and 30, they cause the latter to be correspondingly rotated on the shaft 31. In order to eliminate the necessity of two cams for each plate'tension springs 36 and 37 are mounted between pins 36' and pin 29 and pin 37 and a pin (not shown) similar to pin 2901'1 the respective cams'and plates whereby'there is a tendency to always urge the rotation of said plates in one direction, and the operation of said cams is to overcome said tendency.

The rotation of the cams 3G and 37 is accomplished as follows Suitably mounted in the machine proper, is a shaft 38 to which are mounted sprocketdrums 39 on which is mounted sprocket chain 40, and to which cam blocks-41 which control the pattern to be knitted on the machine may be removably mounted'in a double row. Muledly mounted. to shaft 31' tiple armed levers 42 and 43l' are suitably mounted for instance on shafts 44 and 45 suitably'journaled in the frame of the ma, chine. One arm 42 and 43 respectively of each said levers is sopositioned as to engage with one of the rows of cam blocks 41: on said sprocketchain 40. Links 46and 47 respec tively jointhe arms 42 and 43 to crank arms 48- and 49. respectively, which are-fix edly mounted on the .camrods 35. and 35'. A- spring 50 connected to arms 42 and 43 of said levers 42 and 43 continuously urges the ends of arms 42 and 43" into .en a ement.

with the cam blocks 41. L'ThUS as the arms 42 and 43 ride over the cam blocks 41 which move with the sprocket chain 40 which is controlled by suitable means (not shown) in the machine, the saidlevers 42 and 43" are pivoted about their shafts44 and 45 and.

by means of connecting links 46 and 47 cause the cam rods 35 and 35 and consequently cams 36 and 37 and consequently plates 29 and 30 to rotate in accordance with the displace ment caused by said cam blocks 41 and con sequently cause respective pawls to engage the racks 19 and 20 Having described the means whereby it is possible to secure individual engagement of the respective pawlswith the racks 19 and 54 is adjustably engaged as by means of bol 7 ing or the like. The said rod 54 is slidably mounted on the machine'fra'me and is pro vided with adjustably positioned collars 54 only oneof which is shown whichare designed to engage a member (not shown) fixedly attached to the sliding carriage c,whereby when said member engages one of said collars the said rod will be shifted horizontally,;consequently causing rotation of said lever 53 which in turn will cause rotation of crank arm 51 through link 52j1I1d consequently cause displacement of the pawls which are attached to arms'32 which are fix- The effective length of arm 53 is adjustable by the adjustable positioning of rod 54 in the slot 53 Consequently,by varying the effective length of said arm 53 ultimate displacement of the pawls may readily seen. 7 y

The mode of operation is as follows Suppose it is desired toproduce worklwiththe zigzag stripes shownin Fig.11. In such case the yarncarriers 1), b b 6 and 6 each becorrespondingly varied as is duced wouldisimply. bea series of straight lines. However if. after each complete shift of said yarn 'carriersfroin left to right'the said stops themselves are shiftedprogressively to the left until they havebeen displaced a predetermined distance the first slanting "portion of the zigzag of Fig. 11 will have been formed, then if the said stops are progressively shifted to the right the second zigzag'portion will be formed and-so on. V This operation is accomplished as follows I Assuming that the carriage c is on the eX- treme left hand side of the machine and is beginning to move towards'the right by driving means (not shown) of the machine on the rails a-. As it moves thusly the front plunger cl will ride up over the inclined edge 12 of the stop 12 and down into thecut-out portion 11 in block ll of carrier 6" and when it reaches the right hand end of said. cuteout portion will carry the said yarn carrier along with it until said plunger is released from the block 11 when it rides over the inclined plane 15 of Wing 15 on the rear stop 13, at which instant the forward. end of block 11 will abut against the pin 15 on said wing. ,At this same instant the plunger (Z will have engaged the block'll of yarn carrier 6 and have begun to carry the said yarn carrier 5 toward the right and will continue to do so until released therefrom by stop 14-. At the instant 1 of release therefrom a similar plunger cooperating with the yarn carriers which are carried on the rear bar 10 will have engaged'block 11 of carrier Z) and begun to carry said carrierto the right until released by the right hand stop therefor. At

the instant of release of carrier 5 carrier o will'be carried forward by plunger (5 until it abuts pin 16 on wing 16,. when it will be released and then carrier 7) will be seized by the rear plunger (not shown) and carried to the right to its extreme right hand stop (not shown). The stops for the yarn carrier are so arranged that the feeder of each yarn carrier will be carried up to but not across the starting point of that on the next succeedingyarn carrier.

After moving the carriers to their extreme right hand limits of their strokes, against their respective stops" the carriage 0 continues to move towards the right. During this motion the cams 36 and 37 under the influence of the cam blocks 41 on the sprocket chain 40 will have been rotated so that the pawl 33 on the plate 30 engages the rack 20 on the rod Then when the rod 54 v is shifted by engagement with the part of the carriage as described therebycausing the crank arm 51 to be rotated toward'the right, the said bar-20 will be correspondingly displaced causing corresponding displacement v to the right of the stops 18 and 14; which are attached to strapping means 17 through straps13 and 14 ,-the pins 13 and llc of which engage in the perforations or depressions 20 of saidbar 20. Then the carrier's! begins to move towards the left and in so doing returns the carriers to their left hand positions against their left hand stops. The steps 13 and 14; beingadapted to move as a unit and having been connected to the bar 20 of the front pair have been shifted toward the right and the stops on the rear bar 10 which have been correspondingly connected to the corresponding bar 21 of the rearjpair which is geared to the displaced front bar will have also beenshifted toward the right. Thereby the extreme lefthand I positions of carriers 6 b Z2 and Z2 will have been shifted slightly toward the right and correspondingly the extreme right hand position of carriers Z), b, If and b will have been shifted slightly to the right. Thus on the next right hand movement of carriage 0 each of the latter carrier's b, Z1 b and I) will be carried slightly further to the right. This progressive shift of the stops continues as long as the cam 37 is in the position whereby the said pawl 33 engages the said bar 20. However, as the sprocket chain L0 continues to rotateby means (notshown) in the ma chine in well known manner, new sets of cam blocks 4-1 having a different contour from the original ones will be brought into operative position at such time when the limit of the right hand shift of the said stop is desired at which time the cam 37 will again rotate to a new position releasing the right hand pawl from said bar of'the pair 20 andcau q ing the pawl 82 to engage said bar, whereupon after each left to right andright to left movement of the carriage 0 the previously shifted stops will be given a progressive movement'toward the left. Thus it will be seen, by the corresponding progressiveshifting of the said stops ,to the left and right respectively the zigzag design of Fig. 11 will be obtained. --It will. be noted'that only one of the. displaceable bars 20 0f the pair 19 c and 20 has been used in the operation above described and also the corresponding one 21 of pair 21 and 22; For different designs both pairs of bars may be used.

In the modification of Figs. 8, 9, and 10, a

56 respectively to which opposite ends of said 5 original position relative to one another of said bars 61 and 62 is provided with cut-in I portions 61 and 62 having slanting side walls. The said twobars are adapted tobe slidable relative to each other and the-slid-- ing movement of each bar is adapted to be controlled by one of the bars 19 and 20, the bar 61 for instance being connected to bar 19 and correspondingly the bar 62 being connected to bar 20. The method of connectionbetween said bars 61 and 62 and said bars 19 and 20 respectively may be accomplished by ed to block 55 andthe strap 58 being con-' nected to block 56. Attachednea'r thefront ends of each of said straps 57 and 58 are cross arms 59 and 60 extending in the direction of said bars 19 and 20, the said arm'59 being adapted tolie over bar 19,and thesaid arm 60 being adapted to lie over bar- 20. The,

said arms are provided 'near their ends with pins 59 and 60 which are adapted ache in the respective perforations 19 and 20 in the said bars 19 and 20. Thus any movement of either of the'bars 19 or 20 will correspondingly shift therespective bars 61 or 62. V

The operation with this-modification to knit the diamond design of Fig. 12 is as follows l Initially the two bars 61 and 62 are in such position that the set-in portionsin each bar are counteracted by the'high portion on the other bar, so that the plunger d moving over said bars will not be able, to lower itself into the set-in portion 11 of the yarn carrier blocksll, so that the carriers 6- and b will not be moved as the plunger d sweeps across from right to left and from left to right. Thenunder the influence of the cam blocks 41 and the respective cams 36 and 37 the respective bars 19 and 20 are caused to shift tothe right and to the left respectively, in successivesteps and as this occursthe length of set-in portions between the bars 61 and 62 gradually increases and the plunger d is able to lower itself into the set-in portions 11 of the blocks 11 and carry the said yarn carriers over an everin creasing stroke, the bevelled edges of the set-in portion on the respective bars 61 and 62 serving to actuate the plunger cl to release the same from saidblocks 11 in the samemanner as the bevelled portions on the stop 12 inthe'first modification. v r V 3 After the bars 61 and 62 have been given their maximum right and left displacements, at which time the widest portion ofthe 'dia-' mend will have been knitted,th'e re pective bars under the infiuence'of thegcam blocks 41 andthe associated mechanism are shifted from right to left and left to right respectively, progressively, to bring them to their straps 57 and 58, the strap 57 being connect-J thereby producing the second half of the diamond in the same manner as the first half has been knitted. i 1 v It will be noted that with, the second modification no stop pinshave-been provided on the respective bars 61 and 62 and the same are not necessary if there is sufficient frictional engagement between the yarn carrier mountings and the bar 10. However, if desired such pins could be readily added. I r 1 are only indicative of a plurality of varying designs and. patterns which may be solidly knitted with my attachment as itwill readily be seen that by varying the relativeposition of stops by means of thebars 19 and 20 different designs are possible.
