AMES, HADDONFIELD, NEW JERSEY KNITTING MACHINE Application filed September 5, 1929. Serial No. 390,613.

The said invention relates to knitting machines and particularly to improved means for controlling the operation of the needles to render possible a wide variety of patterns in the manufacture of an individual article knitting either by continuous rotation or by oscillation of the parts, as for making heels and toes, with pattern mechanism adapted to make a large variety of patterns in the same article all without interrupting the operation of the machine.

Another object of the invention is to provide in connection with devices of the character above referred to, coordinated means for idling the instep needles in an automatic manner without interfering with the subsequent renewed operation of the pattern mechanism.

Another object is to provide means for inhibiting the operation of the needle-controlling jacks independently of the other needle controlling means.

In the drawings, reference character 25 (Fig. 1) indicates the main driving shaft of the machine, carrying an idle pulley 26, a low speed pulley 27 and a high speed pulley 28 adapted to be driven by a. belt 29 controlled by a belt shifter of conventional type. The shaft 25 is connected in known manner to a gear 31 (Figs. 2 and 15) meshing with the gear ring 32 of the needle cylinder 32'. Said gear ring and the needle cylinder are supported in a cylinder cup ring 33 shown in detail in Fig. 5, said cylinder cup ring being adjustable vertically to move the cylin der for varying the stitch length as in Patent 1,340,695, May 18, 1920, and also to position 1t for the transfer operation, the specific means for adjusting the cylinder and cup for these purposes forming no part of the inven tion herein claimed. The needle cylinder is provided with latch needles 34, and connections for transmitting to the needles the action of pattern characteristics on pattern forms hereinafter described, jacks 35 for moving the needles, and pressers 36 radially movable to place the jacks into and out of operative relation to a jack lifting cam 35 (Fig. 2) and a jack lowering cam 36 (Fig. 1). The jacks of this machine are intended for reverse plating but may be used for other purposes, as for raising needles selectively into reach of needle cams, etc., as in application Serial No. 25,915, filed April 25, 1925. For so moving the pressers there is provided a series of presser cam levers 37 pivoted at 38 (Fig. 2) on a stud rising from the cylinder cup ring 33. The cylinder cup ring also carries a pawl 39 moved by a spring 40 in a counter-clockwise direction to bring it into engagement with lugs 40' (Fig. 2) at the left-hand end of the cam levers whereby any or all of the camlevers may be held out of position for engagement with the pressers.

A disengaging finger for moving the cam levers away from the ressers and into position to be en aged by t e pawl 39 is indicated at 41 (said nger extending up from a lever 134 hereinafter described) and springs 42 serve to move the cam levers into operating clamped in position when released by pawl 39 and lever 41, subject to the control of an operatively positioned pattern form here shown -as a trick wheel, i. e., a slotted wheel with interchangeable strip-like tricks in the slots, each trick having one or more pattern indications.

In the drawings six such trick wheels are shown at 43 to 48 each trick wheel being mounted on a trick wheel plate 49 having radial slots for bolts 50, the slots being partially covered by plates 49' (Figs. 5 and 6)- held b screws 49" to provide an undercut to recelve the respective nuts 51 of such bolts slidably and permit the trick wheels to be p ace by turning the heads 52 of the bolts. This arrangement permits any necessary radial adjustment of the trick wheels to position them correctly relatively to the cam levers 37. The trick wheels may be such. as are illustrated in application 96,049, March 19, 1926, now Patent 1,722,989, Reissue 17,705, but are here shown as each having a hollow hub 53 mounted on bearing sleeves 54 with radial end flanges and each having a plurality of shallow grooves along their periphery for accommodating tricks 55 held in place by a spring ring 56. A second ring may be used as shown at 56', if desired. In ig. 5'each of the visible tricks is shown as retaining allits teeth, but it will be understood that any or all the teeth may be broken out according to the design intended to be incorporated in the fabric at any particular location, the lowermost tooth being always retained as the. wheel is driven by means of said tooth.

The turret 49 is mounted for rotation about a post 57 supported on a lever 58 (Fig. 2) pivoted at 59 on the bed plate 59 of the machine. A series of screws 57 radially aligned with the respective trick wheels are adapted to bear on a cam 60 for adjustably determining the height of the trick wheel that is in operative position (Figs. 2 and 5) with reference to the plate 49. Correct elevation of the trickwheel plate 49 to keep the butts ofthe tricks level with thecorresponding levers 37 is provided for by means of a plate 60' which is preferably slightly inclined or faced off so that abutments 61 (Fig. 6) on-the plate will ride up on them in an der and its cup ring. The abutments may be the heads of small bolts passing through the trick wheel plate, and they are held in place by nuts 62' (Fig. 6).

For indexing the turret there is provided means comprising 2. Geneva gearing consisting of a notched driven gear 61 (Fig. 6) and position it will rotate the turret one step counterclockwise during a single rotation of the needle cylinder, the operation of the ma chine being slowed down at this time as hereinafter described.

For moving the turret index gear upward into position to rotate the turret and back into idle position there is provided a bell crank lever 67 (Figs. 1, 4 and 5)'connected by a link 68 to a lever 69 (Fig. 5) pivoted on a stud 70 by means of a block 70' which is slidable along said stud. The link 68 has a hook for engaging a bent part of lever 69 and has a finger 71 at its other end for engagement with a cam 72 (Figs; 5'and 11) on a cam drum 73. A spring 74 encircles the link 68 and bears at one end against a part of the frame 75 of the machine and at the'other end against a collar 76 on the link, therefore tending to draw the gear 62 down out of operative relation to gear 61.

The turret is locked in operative position by a flat-sided abutment 77 (Figs. 2 and 5) engaging with any one of the radial notches in which the nuts 51 are located and is disengaged from this abutment by oscillation of lever 58. A spring 78 connected at one end to a pin 78' on bed plate 59 tends to draw the lever and the turret into idle position where the turret is disengaged from the abutment 77. For oscillating the lever to bring the turret into operative position there is provided means comprising a jointed link consisting of a member 79 and a member 80 connected to member 79 by a pivot 81, the member 80 having a handle 82 whereby the turret may be released manually for removal from operative position by contraction of spring 78. Link 80 is connected to a bent lever 83 having at its lower end a roller hearing on a cam face at 84 on the cam drum 73 whereby it will be seen that the low part'85 (Fig. 10) 'of the cam face will permit the spring 78 to move the lever 58 and carry the 3 Geneva earin reviouslV de 'b d. position of vertical adjustment of the cyling g p Sen 8 The cam drum 7 3 has on its left-hand face in Fig.- 1 notches at 86 (Figs. 3,5, 9, 10, 12 and 13) providingiifnotched Geneva gear (see Fig. 3) adapted to be driven by pins 87 (Figs. 1 and 3-) ans. gear 88. The lastlink 93 to a lever 94 pivoted at 95 and having a lug 96- positioned for engagement with a chain 98 on a ratchet 99 loose on shaft 104' and operated by a pawl (not shown) on a lever 100 connected by a link 100' to a disk 101 on the constantly rotating shaft 129. The chain has high links 101 (in the present case only one) for the purpose of elevating the lever. 94 and the link 93, etc., to throw the roller on rock-arm 90 into the path of the cam 89, whereupon the driving gear 88 will engage the notches in drum 73 for rotating the same at suitable times and for suitable distances to cause the turret to be indexed. By loosening the setscrew that secures rock-arm 92 to rockshaft- 91, turning the rock-arm clockwise enough to lift lever 94 off the chain 98 and then setting the screw up again, the turret indexing mechanism may be placed out of operation, so that knitting may proceed indefinitely on the same trick wheel.'

Cam 72 is so located that the end of lever 69 is normally out of operative relation there to and the block 70' is moved toward the front of the machine to bring the lever into operative position, by means of a link 90' connecting the block 70' to a rock-arm 91' fixed to shaft 91.

Another chain 103 is located on the sprocket gear 104 loosely mounted on the shaft 104 which carries the striper drum 147 (Fig. 4) driven by ratchet 99, this chain controlling the striper and not being part of the invention claimed herein. A rock-arm 105 connected to support 106 (which is pivotally mounted for a function not related to the invention herein claimed) is adapted to be raised by a side pin 107 on chain 98 to cause the free end of the lever to engage a fingerv 108 on arm 169 of a lever hereinafter described.

A cam wheel 110 (Fig. 4) on a shaft 111 rotating once for two rotations of the needle cylinder has two cams 112 and 113 for rocking a lever 114 pivoted at 115, which lever extends up to an opening in the bedplate into engagement with a hook 116 (Fig. 2) pivotally connected to lever 58 for oscillating the same to return it to operative position after a low place on wheel 110 has permitted spring 78 to withdraw the turret to an extent only suficient to permit indexing of the trick wheel which is in operative position relatively to the cam levers 37. Such return of the turret by lever 114 also locks the trick wheel against rotation, as both pins 117 bear against its periphery. Such slight oscillation is possible due to the fact that all the train-of parts 58, 79, 80 and 83 can move as lever 58 is moved counter-clockwise against the tension of its spring, the cam face 84 permitting the lower end of lever 83 to move freely to the left in Fig.1.

For indexing the trick wheel a two horned shaft is provided at 117 (Figs. 2, 4 and 5) this shaft being journaled in a block of which the abutment 77 forms an integral part and carrying a pinion 118 (Fig. 5) for driving the shaft, the two horns being so spaced as to engage at opposite sides of the lowermost projection on a trick and lying against or close to the periphery of the trick wheel. A leaf spring 119 bears against the two horns, as shown in Fig. 2. Pinion 118 is driven by a gear 119' (Fig. 8) having notches at its under side fitting it to serve as one member of a Geneva gear and gear 119 is driven by a gear 120 by means of a pin 121 and a locking projection 122. The gear 119 is journaled on a stud 120 fixed to a vertically movable block 123 guided for vertical movement on a stud 124 (Fig. 4) fixed in the bedplate of the machine. Another stud 125 serves to prevent rotation of the block on stud 124. A link 126 (Fig. 7) connects the block to a lever127 bear ing against a cam 128 on a shaft 129 which is the main eccentric shaft. The block 123 carries a pin 131 (Fig. 7) and a bent detent 132 pivoted on the bedplate is normallyturned by a spring 133 (Fig. 4) into position to engage under the pin and support the block in elevated position whereby the elements of the trick wheel indexing Geneva gearing are disengaged. For withdrawing the detent 132 to permit engagement of the trick wheel indexing Geneva gearing a lever 134 is adapted to engage a pin on detent 132 so as to withdraw the detent. Lever 134 has a hub 13410- cated underneath the stack of presser cam levers 37 and two arms underneath those of levers 37, one of which arms projects to the left in Fig. 2 at 135. Its movement is limited by a stud 135' (Fig. 2) the lever being operated by means including a link 145 hereinafter described.

A brake for the Geneva gear 61 is shown in Fig. 2, said brake comprising a roller bearing against the periphery of the gear. The roller is carried by a lever 141 pivoted at 142 on the bedplate and held in operative position against the gear by a spring 143 also connected to pin 78 (Fig. 2), The brake serves the double purpose of holding the turret in indexing position while disengaged from the abutment 7 7 and of also holding the turret in operative position against the presser cam levers 37.

The cam levers may all be withdrawn from operative relation with the pressers by means of the finger 41 mounted on the lever 134 pivoted at 38 underneath the stack of levers 37. Lever 134 is operated by a link 145 (Figs. 2

. and 4) having a loose connection with a bent lever 146 operated by two cams on the striping drum 147, the cam 148 being a toe cam for preventing operation of the needle selecting mechanism while knitting the toe of a stocking and the cam 149 being aheel cam for similarly preventing operation during the knitting of the heel of a stocking. The loose connection of parts 146 and 145 is for the purpose of permitting bent lever 146 to act first (when lifted by the low part of heel cam 149) on the long needle butts for moving them up out of action by means of a link 150, lever 151 and an instep cam 152 on a rocker 152' pivoted at 153. The cam 152 is'moved toward idle position by a spring 154, is slid radially outward by an inwardly facing cam surface coacting with a pin 155 on the bracket 156, is caused to slide radially inward by a pin 157 contacting with an outwardly directed cam surface on the switch, and has its oscillation limited by engagement of a pin 158 with either one of a pair of screws 159, 159. The inward movement causes the cam to lie snugly against the needle cylinder when out of action while the outward movement carries it to a point Where it can engage only the long butts of the instep needles. When the long butt needles have been safely idled the second step of movement. of cam 149 rocks the lever 146 to pull link 145 and rock lever arm 135 to render all the presser cam levers inoperative by means of finger 41, such movement of lever arm 135 also serving to move lever arm 134 to the left in Fig. 2 and so to permit detent 132 to engage under pin 131 so as to prevent engagement of the trick wheel indexing Geneva gearing. A single cam rise serves for the toe, as it is immaterial just Where the change of yarn takes place at this part of the stocking.

A separate control for the jacks is provided by the movable jack lifting cam on its lever 160 (Fig. 2). When fancy knitting is desired a cam 161' (Fig. 2) moves lever 162 (Fig. 4) from the solid line position into the position partly shown in dotted lines, whereby lever 160' is tilted so as to bring the jack lifting cam into jack lifting position. When the cam permits lever 162' to return to solid line position the cam 35 is forced down out of operative position by the jacks.

All the cam levers 37 or so many of them as are held out of operative position at any given time by detent 39 are released at each rotation of the machine by means of a cam 160 (Fig. 3) on shaft 129 which cam in the rotation of the shaft strikes a-lever 161 having a rearwardly projecting arm 162 (Fig. 2) bearing against the downward extension 163 of detent 39 to move the same on its pivot 164 and release the presser levers. The spring 40 returns the detent to its normal locking position and a leaf spring 163 (Fig. 2) bears on a lug of lever 161- to return it to the position of Fig. 3. After the cams 148 or 149 pass the lever 146 the springs 42 return the presser cam levers to normal position (as soon as permitted by detent 39) and so return the finger 41 and lever 134 to normal position, the nose on lever 134 shown in Fig. 2 striking a pin on lever 132 to cause the other arm of lever 132 to be withdrawn from underneath pin 131 so that the control of the'engagement'of the elements of the trick wheel indexing Geneva gearing is again returned to the pattern mechanism shown in Fig. 7. A screw 167 on lever 146 bears on a spring element 168 for adjustment of said element relatively to the rigid part of the lever to vary its engagement w1th the cams and thus adJust the action of the controlled parts accurately.

The side pin 107 on chain 101 is positioned to lift the lever 105 and oscillate lever 169 so operate on cam levers 37 are locked against rotation on their axes by detents vpivoted at 174 and pressed toward locking ositlon by-springs 175. A rod 176 slidab e in post 57 is held against rotation in any suit- 4 able manner and carries a finger at its upper end adapted to engage under the detent 175' of the operatively positioned trick wheel when the rod is lifted by engagement of its lower end with cam 178 which occurs as the lever 58 swings counterclockwise toward the position of Fig.5.

The operation of the -machine is slowed down when the trick wheel plate is to be indexed. For this purpose the cam drum 73 is provided with a face at 180 acting on a roller on bellcrank lever 181. A spring 182 biases the lever in a directionto hold the roller against face 180. A link 183 connects one end of lever 181 with a lever 184, providing a toggle which may be broken by a link 185 having a pin and slot connection with the pivot connecting parts 181 and 183. The link is connected at its other end to one arm of a rocking bellcrank lever 186 fixed to a shaft 187 controlled in known manner from the str ping drum for going into low speed for reciprocating work saidshaft also controlhug the clutch (not shown). A pin on the lower arm oflever 186 bears against lever 184 loosely mounted on shaft 187 and connected at its lower end by a link 189 to one arm 190 of a bellcrank lever whose other arm is a handle 191-. The parts 190 and 191 are pivoted at 192 on a block fixed to the end of a belt-shifter rod 193 of well known type having a spring 194 bearing against-frame member 195 to move the rod and its belt toward the idle pulley 26. At proper times the rotation of cam drum 73 causes lever 181 to break the toggle and permit the belt 29 to move over to second speed pulley 27. The movement of the link of the toggle is limited by engagement of the pin with the end of the slot inlink 185 which link has also moved upward as lever 186 oscillated. After" I the turret has been indexed the cam drum 73 returns the toggle to the position shown and returns the belt to high-speed pulley 28, the handle 191 being, of course, in position to aline link 189 and rock arm 190.

It is thought that the operation of the mechanism will be understood from the foregoing but it may be briefly recapitulated as follows: The parts being in the positions illustrated the wheel 43 will be held by horned gear 117 whereby also certain of the cam levers will be held in place to press against such pressers as have butts at the height to strike such cam levers, and jacks corresponding to the pressers that are forced in will not be elevated, so that normal plating will take place on the corresponding needles if two yarns are fed to the needles in plating relation. The needles corresponding to the pressers that are not pressed inward radially and so to the jacks that are raised by cam 35 and lowered by cam 36' will knit reversely plated fabric. The block 123 is now locked up by detent 132 engaging under pin 131, the cam levers not in operation are locked out by their detent 39, and the trick wheel plate is held against rotation by abutment 77.

If now it is desired to index the trick wheel the cam 128 (Fig. 7) turns to draw the block 123 and its gear 119 down into position where the Geneva gears engage and give the horned gear a rotation of 180. The horns lie at opposite sides of a trick and so merely turn far enough to throw the rear one forward past the next trick. At this time one of the cams at 112, 113 throws lever 114 over to pull on hook 116 and swing the table slightly back to permit the horned gear to rotate without damage to the parts. When the horns reach their proper place they are held there by spring 119, the spring 78 returning the table to place. I

When the trick wheel plate is to be indexed to bring a different wheel into pattern controlling or operative position the chain 98 by a high link lifts lever 94 and so through the train of connections including rock-arm 92, rock-shaft 91, rock-arm 90, cam 89. pins 87,

eneva gear on cam drum 73, cam 72, lever 69, llnk 68, lever 67 and shaft 65, lifts gear 62 into driving engagement with slotted Geneva gear 61. This gear being fast to the plate turns the same step-by-step. Prior to the actuation of lever 69 by cam 72, the plate must be unlocked from abutment 77, and this is done by the rotation of cam drum 73 which acts through lever 83, links 80 and 79 and lever 58 to withdraw the plate for this purpose. Rotation of cam drum 73 also breaks the toggle 181, 183 to permit the belt 29 to shift to second speed until after the plate has been indexed, the sequence of operations being (1) retarding speed, (2) unlocking plate, (3) indexing through cam 72 and (4) speeding up and returning plate to lock-- ing position. At the time the plate is being returned disk 110 is also in a position where one of its cams is acting on lever 114 to assist in returning the plate.

The train of mechanism operated from pin 107 and including lever 105, bent lever 169 and attachments thereto, and bent lever 172 is provided for idling the trick wheel as when a part of a pattern is to be elongated and such devices accomplish the same result as would be had by locating in adjacent slots a number of tricks of the same type on the trick wheel, thus economizing the space on such wheel. It will be recalled that these devices are adapted to hold the block 123 inraised inoperative position by engagement of shelf 173 under link 126. i

The trick-wheel which is in operative position must also be idled when making heels and toes and this is done by means of cams 148 and 149 on drum 147 acting through lever 146,1ink 145 and lever 134 to release detent 132, whereby said detent prevents block 123 from being lowered into position to connect the Geneva gears of the trick wheel indexing devices. The lever 134 by its finger 41 also draws all the cam levers 37 back out of operative position, and after release by finger 41 they are still held by detent 39 until releasedby operation of lever 161 (Fig. 3) such release occurring only during round and round knitting. At these times switch cam 152 is operated to elevate the long-butt needles.

To make unfigured fabric the jack raising cam is lowered by a low place in cam 161' or by the absence of a cam on stripin drum 147, which permits the inner ends 0% levers 162' and 160 to rise and so the other end of lever 160' will be depressed along with the jack-elevating cam 35'.

Many variations in the form and arrangement of the devices above described will be obvious to those skilled in the art, and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as set forth in the appended claims. It is to be noted particularly that other pattern forms can be used and that the forms can be controlled in other ways, e. g., a pattern band as shown in application 96,049 above referred to. It should be noted that the trick wheels are readily interchangeable, as are also the mitting devices between the turret and the needle cylinder for connecting pattern forms operatively to selected instrumentalities,
