In these drawings the row of needles a are operated substantially as in ordinary practice and as illustrated in detail in the applications above noted.

The yarns are fed to the needles by yarn guide eyes, one of which is shown at t in Fig. 5a, mounted on the endless flexible bands 26 to which a reciprocating movement is imparted individually by driving mechanism, which selects the desired band according to the particular yarn which is .to be introduced into the fabric, all as in the applications above referred to. These endless bands are arrested variably in order to fashion the fabric, and for this purpose stops Rs and Ls are mounted on the under side of carrier brackets 36, Figs. -1, 5 and 5b, which stops are controlled to be active or inactive by levers 36c. These stops coact with dogs 34, Fig. 5b mounted on the flexible bands for arresting said bands according to the prescribed plan. The stops are adjusted along the bands to vary the lengths of strokes of the latter according to the fashioning to be performed and for thus adjusting the stops the brackets or carrier blocks 36 suitably guided are moved step by step inwardly towards each other to set the stops to perform the stopping actions on the yarn carrier bands in narrowing the fabric. The stop carriers 36 are therefore moved by a screw shaft 43. This is operated by a train of mechanism involving a gear 43a. on the screw 40 shaft meshing with a gear 43b on stub shaft 430 suitably mounted in the frame of the mechanism at the rear part thereof. v On this stub 'shaft is loosely mounted a drum 43d from which a steel band 43e extends to a lever 43g operated by a cam on the main shaft a. The drum carries a pawl 43k Fig. 11 engaging a ratchet 43' on the shaft 430 by which it is turned to operate through the gears, the screw shaft 43 to set the stop carrier brackets 36 with their stops inwardly towards each other for reducing gradually the length of stroke of the yarn guide carrier bands in narrowing the fabric. The distance of the step by step inward move ment of the stop carrying brackets 36 is that of and the latter on the ratchet 44g fixed on the stub shaft 441:.

' shafts 43 and two needle spaces as in ordinary practice, for fashioning the leg of the stocking. A suitable coil spring 430: returns the drum 43d after each action for a repetition of the operation. The stub shaft has a notched disc 43TL engaged by a detent 43m Fig. 8 mounted in the frame for-preventing overthrow of the screw shaft 43 and to act as an index to indicate if the shaft is in proper position relative to the narrowing sequence.

It will, therefore, be seen that during thenarrowing actions the screw shaft 43 will be rotated in one direction step by step to move the stop carrier brackets 36, Figs. 1 and 6, this action being due to the movement imparted from cam 43h, lever 43g, band 43c, drum 43d, with its pawl operating the stub shaft through the ratchet thereon, and from stub shaft the movement is transmitted to the screw shaft through the gears 43b and 430..

For operating the narrowing points step by step along the needle row, for narrowing, the carrier blocks 44a of these narrowing points are moved by the screw shaft 44b through the gearing 44c, 4401, the former being on the screw shaft front stub shaft 440:, suitably mounted in a frame part. This stub shaft is provided with a drum 44' operated in one direction by a steel band 44e extending back over a guide sheave 44h Fig. 2 to the same lever 439 which operates the band 43c before mentioned. The drum carries a pawl 44f Fig. 9 to engage a The drum is loose on the stub shaft and is returned by a suitable spring 44y after each action of the pawl.

A shield or shutter 44" Fig. 9 holds the pawl out of engagement with the ratchet 44g when the pawl is in retracted position. When the pawl is to function for turning the stub shaft 440: and the front screw shaft 44b for narrowing, it moves off of said shield into engagement with the ratchet to turn it sufficiently to rotate the screw shaft for a two needle space movement of the narrowing points in narrowing. When, however, the pawl 41 f is to turn the screw shaft for forming picot the shield is automatically adjusted by lever I311, and pin M71 (as a result of setting the picot bar in operative position) to set the shield 44" in position to take only one tooth of the ratchet, as fully described in said application No. 596,642.

When back-racking is performed as will be hereinafter described the pawl 44f will be out of engagement with ratchet 44g as shown in Fig. 9 so that stub shaft 44x then can be rotated in the opposite direction from that which the pawl would give it. This pawl during back-racking, therefore, offers no resistance to the backward rotation of shaft'44a: and ratchet 449.

The stub shaft 443: has a notched index or centering wheel 44m engaged by a spring detent 4411 mounted on a suitable part of the narrowing frame 41.

Thus it will be observ d that both of the screw 441) are operated for narrowing from the same cam 43h Fig. 2 on the main shaft a through the lever 43g, the bands and the connections above described;

Back-racking mechanism After a stocking leg is finished it is necessary to operate the screw shafts 43 and 44b backwards to return the blocks 44a with their narrowing points, and also the carriers or brackets 36 with their yarn carrier stops to position for from the pattern drum A Figs.

making the next article, and for this purpose back-racking mechanism is provided operating through means on the stub shafts 43c and 44a: to turn the screws 43 and 44b backward. This mechanism is brought into action automatically as the machine continues to run, and during a period following the completion of knitting i. e. following the completion of the stocking leg, said mechanism being operated under the power which operates the machine.

The back racking mechanism is controlled 2 and 4 through a rock shaft I, an arm 2 thereon connected by a link 3 with a bell crank lever 4 which operates a spring pressed plunger 5 which shifts laterally a fork 6 carrying a roller 1. A spring 6a presses the fork in opposition to the plunger. This roller is shifted by the fork into line with a cam 8 on the main cam shaft a of the machine. This roller is carried by a lever 9 which is mounted pivotally on an extension of the rocker shaft 22 or stitch control shaft.

The lever 9 is connected by a link It! with and operates in one direction a chain Ina running over a sprocket wheel [2 fixed to abevel gear wheel l3 which is loose on stub shaft 430. This chain is operated in reverse direction by a spring lllb. The gear wheel I3 meshes with a bevel pinion l4 on a transverse shaft l5 which carries a crown pinion l6 meshing with a crown gear H on the stub shaft 44m. The shaft I5 is journalled in the frame bracket l5a which is supported by the stub shafts 43a: and 44m.

The crown pinion and gear are provided in order that the movement of the narrowing frame 41 can take place without disengagement of the gearing, it being understood that the screw shaft 44!), and the stub shaft 44a: and other elements of the drive for the screw shaft-44b are mounted on the said narrowing frame whose center of ro-. 'tation is not coaxial with the center of the stub shaft 430. For a like reason the frame bracket I5a is forked at l5b where it engages stub shaft 443;. The two gears l3 and I1 (bevel and crown gears), are loose on their respective shafts and each carries a pawl marked respectively l3a and Ila to engage a'single tooth l3b, HD in their respective ratchets I3c, 11c, fixed on their respective shafts 430, 443:.

Each of these pawls is controlled by a shutter --1 or shield marked respectively |3d and I111. The forward shutter is pivoted on the stub shaft 44:: and has a downwardly extending arm l8 to be operated by a lever l9 pivotedloosely on a pin 20 mounted in a frame bracket 2|. spring 'pressed by a coil spring 22. It has an arm 23 which is operated by a sliding cam 24 on a rod 25 mounted slidably in the bracket 2| and pressed in one direction by aspring 2'! bearing on the bracket at one end and on a collar 28 fixed on the sliderod 25. This rod has fixed thereto an arm 29 which is in the path of the right'hand narrowing block 44a which carries the right group of narrowing points so that when the narrowing block is at the right hand position the shutter, or shield lld through the described connections, will be in position to hold the pawl lla out of operation, i. e. said pawl will not operate the ratchet but will move back and forth on the shutter or shield. A coil spring 30 tends to pull the shutter rearwardly at all times i. e. into a position where it will shield the ratchet from engagement by the pawl when narrowing operations are being performed.

The coil spring 22 tends to keep the lever I9 This lever is (which operates the shutter) against the sliding cam which operates it. The throw-out position of the shutter or shield is assumed when, in the racking operation, the narrowing point carriers are racked back automatically to their extreme outer positions. When the right hand narrowing point block moves to the left for narrowing, the shutter is withdrawn so. that the pawl (when it is again brought into operation'by the reciprocation of the chain and gearing) will then engage the ratchet for the back racking operation. This withdrawal of the shutter is due to block 44a leaving arm 29 whereupon spring 21 will move rod 25 leftward, thus withdrawing cam 24 from lever i9, 23 which due to spring 22 then moves away from arm l8 of the shutter and allows the spring 30 of the shutter to rotate said.

shutter and thus free the pawl l3a to engage its ratchet.

The shutter l3d of the rear mechanism is operated by a rod 3| fixed by a set screw 3|a to the stop carrier 36. This rod, when the right hand stop carrier 36 is racked back to the extreme right or idle position comes against a bell crank lever 3lb pivotedto the bracket 3ic. This dividually controlled by its own shutter or shield and pawl, but both sets are dependent for their operation upon the main operating mechanism i. e. the main pattern mechanism and the set of connections before described including the link It), chain Inc, and associated parts.

One reason, therefore, for the shutter or shield arrangements at both the "front and back-racking mechanisms is to permit each mechanism to exert individual control over its own actions. This provides for the difference in back racking as between the narrowing point carriers 44a and the carriers 36 for the stops of the yarn guide carriers, which difference is necessarily due to the fact that the carrier stops are adjusted two needle spaces whereas the narrowing points are adjusted at the heel tabs two needle spaces inwardly and one needle space outwardly.

Further the shutter or shield for the back racking mechanism of the screw shaft 44b of the narrowing point carrier 44a is provided so that the back racking pawl is held out of action while narrowing goes on. This is true also of the shutter at the rear mechanism 1. e. it is held in position to render the back racking pawl of this rear set of mechanism out of action while the carrier stops are being adjusted inwardly for narrowing.

Through the use of the individual controls each depending upon the resetting of its main elements (i. e. the narrowing point carriers 44a inthe one case and the stop carriers 36 in the other) the main operative mechanism controlled by the main pattern mechanism can have movement beyond that which is necessary to effect racking back of the parts to normal position, and yet no damage will be done either set of mechanism, each controlling itself, through its pawl and ratchet under control by its own shutter or shield.

The back racking having been started automatically by the pattern mechanism through the machine continues its operation, after the back.

racking has been done, for bringing in a new yarn to start the new stocking and continues in operation until nearly one new course of yarn is laid in the needles. rest automatically by the let-off mechanism.

The operation now (i. e. when the machine stops) has been brought to the point where the operator by slight manual operation, quickly performed, can complete the preparation for the beginning of a new fabric, involving turning the machine manually to complete the new course and placing the welt bar into connection with the first course.

The actions may be stated to be as follows:

(1) Automatically laying the new thread nearly but not quite, across the whole row of needles, then (2) automatically stopping the machine, (3) then completing the laying in of the remainder of the first course, (4) by turning the machine over slightly by hand and stopping this action at just the rightmoment to prevent dropping this first course,- (5) then placing the welt hooks in connectionwith this first course and (6) then throwing on the power to drive the machine.

As set forth in application No. 590,942 above mentioned the changing of yarns is controlled by selector mechanism whichis set to discard one yarn carrier and substitute therefor another band with its yarn carrier as called for by the main pattern mechanism, and it will therefore be understood that the operation above described readily can be performed by continuing the operation of the machine after the stocking leg has been completed, during which continuation the back racking is performed after which the feeding of yarn to the needles is resumed automatically until the new course for beginning the next stocking is partly laid in the row of needles.

In said prior application it is also set forth that a reciprocating driver is employed for the yarn carrying band or hands, said driver having pawls which will pick up or drop the yarn carrier means according as called for by the pattern mechanism, all the above actions being performed while the machine continues to run.

In the drive for the front pawl and ratchet mechanism the crown gear is connected by an adjustment so as to time it relative to the rear set of mechanism. This adjustable connection involves a screw and cone arrangement shown in Fig. 7 at l'lk.

It will be seen from the above that after the completion of the stocking section the power drive continues to function, and from a common source of power transmission, i. e.'the cam 8, lever 9, link It), chain l0a, etc. the back-racking mechanism of both the front and rear screw shafts is operated, each mechanism throwing itself out automatically when the appropriate part, point carrier or stop carrier, has been returned t'o' i'ts starting point, and furthermore, the new yarn is selected and laid in most of the needles for the first course of the new fabric and then the machine stops.

Each of the front and rear sets of back-racking mechanism can be operated by hand, each being provided with a hand crank mounted on the stub shaft, these being marked respectively 441i and 439'.

The machine then comes to v In Fig. 11 is shown a cam 241) on yarn changer shaft 1) as in application No. 596,642 for operating a lever 35 to throw pawl 43k out of operation so that the screw shaft 43 will not be operated during the formation of picot.

At 45 is shown a toothed wheel which is operated by a retrograde pawl 46 in the formation of picot. It forms no part of the present improvement, and is mentionedmerely for identification. It and the retrograde pawl 46 are disclosed in both of the applications above mentioned.

During the knitting of the stocking the backracking or restoring pawls 1311, Ha will be in their retracted positions on the high parts of their respective shutters I3d, I'ld, where said pawls will rest out of action and out of engagement with their single tooth ratchets. They now have no movement became their operating connections are idle owing to the fact that the roller 1 is now out of line with the cam 8. The pawls in their idle positions will not interfere with the rotation of the stub shafts during narrowing because their ratchets will be free to turn under said pawls.

At the completion of the stocking section, and while the machine continues in operation, the mechanism A through the connections described will shift the roller 1 into line with the cam 8 and the pawls will be given their prescribed effective strokes off from the high parts of the shutters and into engagement with their single tooth ratchets. Thus, back-racking will be inaugurated and will be continued until the rod 3|, carried by the right hand stop carrier or bracket 36, and the cam 24, operated by the right hand narrowing point block, will operate the described connections for shifting their respective shutters I311, I111 so as to advance their high parts and thus close the single tooth spaces of the ratchet to prevent engagement of the back-racking pawls therewith. This cessation of the back-racking or restoring action will take place individually at each of the front and rear back-racking or restoring mechanisms under their own control respectively, and despite the fact that the driving means for the pawls may continue to operate, said pawls in any further action performing idle strokes, on the shutter and out of line with the single teeth. Now when the machine operates for making the next stocking leg blank, the shutters will remain in their positions guarding or closing the single teeth of the ratchets until narrowing begins and the stop carrier or bracket 36 moves inwardly towards the center of the machine, and the narrowing point carrier likewise moves along the needle row inward towards the transverse center line of the machine whereupon the rod 3| and the cam 24 will be withdrawn from the mechanism which has been holding the shutters Hid and Ild in their positions closing the teeth of the single tooth ratchets, and these teeth will be exposed for the engagement of the pawls when these are operated, it being understood, however, that said pawls will not 'be operated until the knitting of the stocking blank is completed, said pawls remaining out of line with the single teeth of said ratchets owing to the fact that they still remain in idle position on the high part of the shutter. When the stocking blank is completed, then the pattern mechanism gives effective movement to the pawls as before described and the cycle is completed.

Stops are provided at l3g, Hg to limit the movement of the shutters in closing the teeth of the back-racking ratchets I3c and Ho.

It will be seen from the above that when the narrowing pawls are operative, the back-racking pawls are held out of action and conversely when the back-racking pawls are in service, the narrowing pawls, see Figs. 9 and 11, are held out of action in their retracted positions.

A spring plunger 3| acting on lever 3lb resets the operating connections of the shutter l3d when the stop carrier 36 by its movement leftward, Fig. 5, withdraws the rod 3| from pressing against said lever. Springs I3x and Has, Figs. 10 and 12, press the back-racking pawls to their work. A stop 9a limits the movement of lever 9, Fig. 2.

At 3|.I2, Figs. 5 and 12, is shown a stop mounted on the gear wheel 43b which, in the final movement of back-racking, comes against the end of lever 3|b when this has been moved into the position of Fig. 5, and has moved the shutter 13d to close the tooth in the back-racking ratchet.

This stop determines accurately the final position of the back-racking mechanism.

The invention is not limited to a machine in which there are a plurality of yarn feeds with an endless band for each yarn guide, and a stop for each band, as fashioning can be done in a single feed machine with which may be associated back-racking or restoring mechanisms for the stop means and for the narrowing mechanism of the general form disclosed herein.

In the operation of back-racking, the backracking pawls are carried around the axis of the stub shafts and move the one tooth ratchets not more than a full revolution at each action.

It requires a number of these revolutions to effect the full restoration of the narrowing point carriers and the yarn guide stops. At each backward movement of the pawl it will drop into the one tooth ratchet and give it another revolution on the next action.
