point`,ns indicatedin smid Fig; 12:. When 'the cern-cylinder moves in the' opposite clireoinn, nr; indicated in Fig. 13, the wave 18 truvels'rom right to left, the needles on the leftlside beingrawn down and the needles 13o f, 'loop 32. The rin on the ri ht being raised, and the thread should be ed to the knittin oint. In other words, the thread shou d e guided to the needles in advance of the knitting-point in whichever direction the cam-cylinder is moving. Since in reciprocating knitting the wave in the needles formed by the knittingcam travels first in .one direction and lthen in the other, the employment of. a single knitting-cam involves the use of means for leading the thread to the needles from opposite sides of the knitting-cam or the knittmg-point as the cylinder reciprocates. In the construction shown this means comprises a thread-guide which is shifted from one side of the in?? .lng-point to the other as the cam-cylinder rciprocates, so that the thread-guide travels about the needles inadvance of the knittin -point as the cam-cylinder moves back an the needle-cylinder. The devices for effecting the movement of the thread-guide and the manner of'mountin the guide are novel in themselves and ma e employed with advantage in other mac 'nes in which it is desired to shift the relative position of the thread-guide and knitti pomt. The latchguard 29, in which the main thread-guide 30 1s formed, is pivoted to a post 3l, rislng from a plat'e 32, which is secured to a ring 33, mounted in an annular groove in the top of the sinker cam-ring 21. The thread is led from the usual stationary guides through a guide 34 to the main thread-guide 30, and thence passes to the needles, andthe vertical position of the thread-guide and,latchring when in action is deterrnned by an adjustable screw 35, arranged to engage the plate 33 is frictionally held in place upon the sin er cam-ring by friction-plates 36, secured upon the cam-ring and having spring-tongues 37, which bear upon the upper surface of the ring 33.

The smker cam-ring is connected with the cam-cylinder through an arm 38, Figs. l and 14, rejecting from a plate 39, secured to the un er side of the sinker cam-ring, the ends of the plate forming two of the plates 23 before referred to. The arm 3S is rovided with a recess 40 in its end within wliich fits the upper end of a shaft 41, carried by the cam-cylmder. The sinker cam-ring, therefore, moves with the cam-cylinder, and the ring 33, which carries the thread-guide 30,- also moves with the cam-cylinlder, the thread-guide being held in proper relation to the knitting-eam by the friction-plates 36. With this construction there is a positive tween the cam-cylinder and sinker cam-rimv holding them always in fixed relation to eac Y other, and the head may be operated at high s eed without shock or jar and without anger of the sinker cam-ring getting out of proper relation with the cam-cylinder, as in machines in which there is lost motion be forth aboutthe slide 43 strikes continues to move, -is shifted o'n the sinker cam-ring until it occupies the position with relation to the knitconnection berin and in which a friction is ap lied to the siner carn-ring to prevent the dlsplacement thereof. g g

When the cam-cylinder is reciprocated in knitting the heel andtoe, the thread-guide is shifted from one sidiJ of the. knitting-cam to the other by means of a-stop in the orm of a plate 42, secured to the sinker-ring 1 on the needle-cylinder u on the side where the inactive needles are located, which plate is enga ed by a projection on en of each stroke of either direction and arrests the movement of the ring 33 durin the last part of the stroke of the cam-cylin er. This arresting of the plate 33 while the camcylinler contmues its movement causes the thread-guide to be 'shifted to the o posite or rear side of the knitting-cam, which rear side becomes the front side when the canvcylinder begins its return stroke. The projection on the` ring 33 for engaging the late 42 is in the form of a slide 43, mounte to moveradially in, an arm 44, extending downward from the post 31, Fig. 1.

During rotary knitting the slide 43 isdrawn outward, so that it passes b the plate 42-as the cam-cylinder rotates. Yhen the motion of the cam-cylinder is change from rotary to reciprocating, the slide is moved inward, so that it will engage the plate 42.A The operation of the devxceswill be understood from an inspection of Figs. 10 to 13. Su polsefthe cam-cylinder to be moving as indicatedby the arrows, Figs. lOvand 12, the thread-guidewill be in advance of the knitting-cam as the cam operates the active needles. After the knitting-cam nas passed beyond the active series of needles and as the cam-cylinder is nearinr the end of its stroke in this direction the plate 42,- as indicated in dotted lines, Fig. l0, thus arresting` the movement of the ring 33. The cam-cylinder however, and the ring 33 ting-cam and sinker camring. (Indicated in Fig. 11.) This brings the thread-guide 30 on the opposite or rear side of the knitting-cam or upon the lett side in Fig. 12. The camc linder is now reversed, and the left side of the knitting-cam, on which the thread-guide is, becomes the front side of the cam. As the cam-cylinder moves in the direction of the arrows', Figs; 11 and 13, the thread -guide therefore travels in advance of the knitting- 'cam until the ram has passed beyond the active needles, wnen the slide 43 engages the opiosite side of plate 42, as indicated in dotte lines in Fig. 11, thus causing the threadguide to be returned to the right side of the knitting-cam preparatory to the next stroke of the cam-cylinder from lert to right.

As has already been explained, the needles on the right of the wave 18 move downward the ring 33 near theA the cam-cylinder in [tween the ,cam-cylinder and sinker canithe needles from the left of IOO first needle-butt in the active series after it comes up the incline 17 strikes the back of the picker, which swings up to allow the butt to pass and rides over the butts until they .rave all passed, when it is swung down into the position shown in Figs. 8 and 20, ready to lift the lirst needle on the next stroke of the cam-cylinder from right to left. The picker 52 is of similar construction, being provided with an inclined edge 56", which engages the edgeref an inclined cam-surface 57 on the plate 11 and being mounted upon a rod 58 and acted upon by a spring 59. There are also two pickers G0 and 61 for depressinnr individual needles during are similar in construction and inode of operation to the lifting-pickers. The picker 6U is mounted on a rod Y62, carried by the camcylinder, and is provided with an inclined edge or ealn 63, which cooperates with the edge ol" an inclined cam-surface 64, formed on the guard-plate 65, Figs. 6, 7, and 21, and the iclrer G1 is mounted on a rod 66,'earried through a the widening, which by t c cam-cylinder, and is provided with an inclined edge or cam 67, which co erates with the edge of an inclined cam-sur ace 68 on the guard-plate 69. The pickers 60 and 61 are held yieldingly in position to engage the butts of the inactive needles by springs 7l), which hold the pickers forward against collars 72 and upward against stops 7 4. On the, forward stroke of the picker it acts to depress the needle-butts at the end of the. inactive series and then rides under the needlebutts until they hoveall passed, and on the return stroke ol" the picker it is swung downward by the engagement of the medle-butts with the rear side of the picker and rides under the needle-butts, as indicated at (il, Fig. 21, until the. butts have all aissell, when it swings up into position, as im ieated at 60, Fig. 21.

ln the construction shown the depressingpickers are provided with lips formed to engage and depress two adjacent needles, and the lifting-pickers are continued in operation during the widening operation. The general operation of narrowing and widening is well understood and will not he described in deiaiL 'lhe pickers are thrown into and out of operation at the proper times by means ol' the guard cam-plates (i5 and 69, which are so mounted that they may be moved to engage either the lifting-pickers or the de iressmgpickers, and this manner of contro ling the operation ot the pickers forms one of the features ol the present invention. 'lhe guardplate 69 is secured to a slide 76, liig. 24, guided in a slot 77, formed in a block 78, mounted inside the mun-cylinder, and is provided on its outer side with a thin plate 79, arranged outside the path olI the needle-butts und in position to engage the end ol the lifting-picker 51. 'l`heguard-plate65, Figs 19 to l l 21, is secured to a similar slide guided in a slot and is provided with a, similar plate 81, arranged to engage the endY of picker 52.

The guard-earn 69 is o erated three h s. plate 82, secured to the slide 76 and rovided with a de ending arm 83, whic asses ole in a plate 84, secure to a slide 85. The slide is guided between the cam-cylinder and ledge 9, as shown in Fig. 26. The slide 85 is provided with a radiallyextending slot 86, which is en aged by a crank-pin 87 on a disk 88, secure to a vertical shaft 89, mounted on the cam-cylinder. The guard-cam 65 is o erated through a similar plate 90, connecte with a similar slide 91, which is provided'with a radial slot 92, nga ged by a crank-pin 93 on a, disk 94, secured to the crank-pin 87 the crank-pin 93 being diametrically opposite the crank-pin 87, Fig. 5.

During rotary knitting the parts are in the position indicated in Figs. 5 and`19, with the guard- cams 65 and 69 in their forward posil tion against the i'nclined ends of the plate 11. In this position the guard-cams act to direct any raised needle-butt onto the led e 9 and to prevent any needle-butt rising a ove the ledge as it passes off the cam 1li-that is to say, they act as guard-earns for. insuring the proper movement of the needle-butts. They also act to hold the lifting-pickers back out of the path of the needle-butts. rowing is' to begin, the shaft S9 is uarter-turns. tie guard-cams into the' )osition shown in Fig. 21, thus leaving thelifting-piekers free to swing down into operative position. The second quarter-turn of the shaft draws the guard-cams into the position shown inA Fig. 20. As the cams move into this position they engage the rear sides of thedepressingpickers 60 and 61 and turn them down out of the path of the needle-butts, as indicated. When the narrowing is completed, the shaft 89 is given a third quarter-turn, bringing the guard-cams into the position shown in Fig. 21 thus leaving both the lifting and depressing pickers free to swing into operative position. When the widening is completed, the shaft is given a fourth quarter-tum, bringing the parts back into the position shown in Fig. 19. As the guard-cams move into this position the plates 79 and 81 engage the outer ends of the pickers 5l and 52 and force them along their guiding-rods, so that the are turned upward and outward behin the guard-earns and plate l1.

'lhe construction of the oam for throwin the needles not used on the heel and toe an the. manner of operating the cam is novel and embodies features of invention. The needles are thrown out of and into operation by a swinging cam 95, Figs. 1, 4, 19 to 21, and 27 to 29, which is secured to the inner end of a shalt 96, mountedon the cam-cylinder above the shaft 89.

The inanner of effecting the transfer of the top of the needles when the needles are thus leveled is fully explained in Patent No. 656,218, dated August 21', 1900, to which reference may be ha In the head shown, as in the head of the patent referred to, the tops of all the need es are brought below the sinkers by directing the needle-butts into a guideway or groove inside the cam-cylinder below the knitting-cams. The major portion of this guideway 123 is formed by the under edge of the ledge 9 and the upper edge of a ring 124, secured inside the cam-cylinder in the same way that ledge 9 is secured, the space between the ledge 9 and ring 124 being substantially the width of the needle-butts. In order to guide the needle-butts into this groove, the plates 14, 15, and 11 and the guard- cams 65 and 69 are mounted upon a verticali T-sliding block 78. The block 78 provide with a rib 125, which fits within a guidewa 126, formed in the inner surface of a curve( plate 127, secured to the cam-cylinder and forming a art of its wall. The block 78 is held with t e rib 125 in the guideway by a screw.l28, which asses through a slot 129 in the plate 127 and ias a fla ,ge 130, formed thereon, which eigages a plate 131, bearirg upon the outside of plate 127. The block 78 is moved verticali f by means of a ram 132, secured to the sha t41, and havin a cam-groove which vengages the o uter el:

of the screw 128. 'lhe shaft 41 is mounted in a bracket 133, secured to the outer surface of the plate 127, and is provided with a hau-die 134, by which it may be turned. The

.shaft 41 is held in its normal position by a spring 135, Fig. 5, which bears'upon a llat place 136 on the cam 132.

When the needle-butts are to be directed into the groove 123, the shalt 41 is turned and thc cani 132 raises the block 78 until the parts are in the position shown in Fig. 22. This brings the under sides of thc plates 14 :ind 15 into line with the under edge of ledge 9 and brings the upper surface of a rib 137, which is Isecured to the block 78, into line with upper surface ol ring 124, the space between the rib 137 and plates 14 and 15 Forming a part of the groove for leveling the needle-butts- The 'min-cylinder is then revolved in the direction of the arrow, Fig. 22, and the neod|obutts on the ledge 9 pass down the inclined- Ycam-surface 138 on the glatte 151into the guideway 123, those needleuttsrwhieh are lifted by the upward Inovement of the plates, 14 and 15 being depressed onto theledge 9 by the cam 95 and also passing down theineline 138. After the top has been. transferred to the needles in the manner set forthV in the Patent No. 656,218, referred to, the block 78 is returned to its lower position, brin ing- `the arts into the position shown in `19 'lhe needle-butts are returned into nitgting position by a cam. 139, secured to the ring 124 and arranged to pr0- ject above the rib 137 an between the adjacent ends' of the plates 14 and 15. As the the grooves 123 pass down the incline 138 under the plate 15 and up the cam 1.39 onto the incline 16, the butts which were-carried down by thev depression of the plate 14 pass.- ing up a cam-.surface 140 into the guideway '$123.

The space between the ends of plates 14 and 15 is brid ed over by ayielding mounted bridge 141, wiieh is mounted to. slide radially in a recess in the block 78, 1. The bridge is provided with an inclined under side 142, which bears u on the inclined upper edge of cam 139. ghe bridge-piece 141 is loosely mounted in its recesgLsdo. that it may have a slight vertical play, ahd'is pressed forward by a s )rin 143. The bridge is held up in position y t e engagement of its incline 142- with the cam 139. During the knitting the needle-butts pass over the upper surface. When the butts are forced upward by the cam 139, they strike the under side-142 and force the bridge-piece back, so that they may pass by saidpiece onto the cam 16. The bridge 141 also forms a yielding cushion durmovement of the needle-butts ,and holding them up against the end of the knittin cam. This construction enables the head to e operated at a high rate of speed and insures a uniform fabric, since the extent of the downward movement of the needle is determined by the end of the knitting-cam and the downward movement of the needle is arrested by the cushion and not by the resistance of the loo bleing drawn.

or convenience in setting up the machine and in removing the parts for repair it is preferred to mountthe pickers as well as the cams for guiding the needle-butts during the knitting upon the block 78 and to so mount the block that it may be readily removed with the attached parts. This result is accomplished in the construction shown in which the section 127 of the cam-cylinder supports the block 7X and the arts attached thereto. 'lhis section may e readil removed by removing the screws by whicliit is attached to the'cam-cylinder.

While I have described the features of ining the knitting for arresting the downward cam-cylinder is rotated the needle-butts in y vention in connection with a knitting-head in which the knitting-weve is caused to travel about the needles by rotating the cam-cylinder, it will be understood that the travel of the wave may be produced by rotating the needle-cylinder, in which case the cam-cylinder would be stationary.

With relation to the turning oi thepickers upon their axes as they are moved longitulo dmally thereoi, it is not necessary that the surface with which the pickers engage in turning shell be a eem-surface, because the picker itself is provided with a cem-surface .on its reer side, and the engagement of this i 5 Veem-surface with any suitable surface would serve to give the requisite turning movement to the picker as it is moved lengthwise on its axis.
