tal reciprocating movement to the needle bars.

A bracket 34 extends up from the top of the bed plate 3 and has a bearing in which is pivotally mounted a rocker arm 35, the lowe1 end ot which rocker arm is bifurcated and straddles the lam 33. so that as the cam 33 rotates. the upper end of the arm 35 will be rocked longitudinally.

The stitcletightening device is operated by a cam 24 on the shaft 6 which cam gives a reciprocating movement to the shoe 25 .which is eonnnunicated to the rock arm 36 by the rod The'rock arm 36 is rigidly mounted upon a rod 3T secured in standards 4 and 5 parallel to the, shafts and upon the outer end thereof and extends downwardly therefrom. Rigidly mounted upon the rod 3T between the inner sides of the standards 4 and 5 are two upwardly-extemling roeli arms 38 and 39, to the upper ends of which are pivotally secured the inner ends of a U-shaped pulling rod 40. ImmediatelyY below the opening 41 in the bed plate 3 are two spaced fixed parallel rods 42 and 4I-molmted one above the other in the standards 4 and 5 between which last rods the pulling rod 4() is adapted to be. moved. rl`wo grooved pulleys 44 and 45 are loosely mounted upon therod 3T and a similar pulley 46 is secured upon the shaft 6 at the side of the cam 13 around which last pulley is passed a band 4T which in turn passes over pulleys 44 and 45 aml then extends downwardly and passes around a pulley 4S. 'lhe pulley 4S is mounted upon one end of a shaft 45) mounted in bearings upon the table 1. which shaft has secured thereon a worm 5t), which worm meshes with a worm gear 5; mounted upon one end of a'talte-up roll 53. 'l"he roll 5I is mounted in the frame 54 mounted upon said table. and a similar roll 55 is mounted therein at the side of the roll 53. The other ends ol' these rolls are colmecteitby gears 56 and 5T so that they move togetherllxtending upwardly from the top ot' the bed plate 3 centrally thereol are two standards 5S and :'tl which are provided near their lower ends with slots titl and 6l in which are slidably mounted the needle plates 62 and 63. Suitable mechanism is pro vided for rta-iprocating the needle plates 62. (i3 simultaneously but in opposite directions. ln the. construction herein shown the front needle plate 62 is provided at one end .with a projecting arm 64`to which is p'ivotally connected the upper end of the end of a rocking lever 66 that is pivotally mounted centrally upon the stud 67 mounted in the top of the bed plate 3. vThe rear needle plate 63 has a similar bracket 68 rigidly seemed thereto which is also pro'- vided with a slot 168 that' receives a pin 169 secured in the opposite end of said rock I ing lever 66. With this construction it will be seen that when the arm 64C, moves to the right, Fig. 12, thereby to move the Afront needle platei62 to the right, the bracket 65 which is rigid with the needle plate 62 will Vact on the pin 166 thereby to swing Vthe rocking lever 66 about its central pivot. This turning movement ofthe lever 66 lWill operate through the pin 169 and bracket 68 to move. the rear needle plate 63 to the left.

The pin-and-slot connections between the rocking lever 66 and the brackets 65 and 68 permit of this movement without causing any binding of the parts. Similarly, when the projection 64 is moved to the left, Fig. 12, the front needle plate 62 will be moved to the left. but the rear needle plate will be moved to the right through the connections above. described. These needle plates have provided between them a lon- 2" litudinally-extending slot 69 throuOh which passes the completed fabric when tie machine is operated. l On the outer surfaces of the needle plates are formed a series of slots in the usual manner for-the reception of the needles T0. The needles are of the usual kind used in machinesvof this class and the hubs 71 project outwardly from the slots.

Each needle-lifting plate is provided with a needle-lifting bar 72 which are fastened together and slide upon the needle plates. the front needlelifting bar being supported upon the upper ends of medle-lifting rods 16 and l1T y\vhereb a vertical reciprocating movement is imparted to the needles. The hubs of the needles rest upon the top of the needle-lifting bars. and a slotted bar 73 is adapted to rest upon said bars to hold the lmbs of the needles against displacement. and a retaining strip T4 resti/empoli said slotted bar and the hubs ofthe ifieedles, upon which retaining strip is mounted the upper i'nwardly-extemling leg of an inverted L- ('ap T5 is secured to Laaaaioa through an aperture in a oraelr'et 77 en the standard 59 and is .connected at its upper enel to a cross-head 78. Two cross hars 79. and are centrally mounted on a rod 81A for apivot. Two link bars 82 and, 83 are loosely mounted at their lower ends in the cross-head "(8 by a pivot 8a, and the otherv ends are loosely connected 'with the lowerv ends ofthe oross-barsNQ and 80 by pivots 85 and 86, respectively.

Apush-rod rises and descends.

There are two parallel upright posts 101 and 102 mounted at their lower ends in the bed plate 3- to extend upwardly therefrom.

The front set of side thread carriers 103 are connected at their upper ends by a spreader har 9% whose function is to spr ad 'the threads or yarns. In like. manimr. the rear set of side thread carriers 101- are eonnee'red by another spreader har of similar oonstruotion.

The push-rod 31 operates the end thread guides and extends up looselythrough an 3 and .is Connected at tendinglegor a hell crank lever'109 pivotally'inounted upon rod 81. The other leg of the lever 100 extends upwardlyrand spports one end'of' an oscillating rod 110, which rod 110 extends parallel with rod 81 and between the out-'turned ends or` the side thread guides. The end thread` guides 111 and 112 (Figs '10 and 11) are arranged in pairs and described as follows:

Each pair of these guides is composed el" a lon..Cr ineinher 111 and a short member 112. l/lenoer 111 extends upwardly from rod l1() and is supported its upper end yupon a pivot'rod 113 mounted in hearings sorured 'to posts 101 and 102, and is provided with a transverse slot 114 through which' the rod 81 The short member 112 is pivotall7 mounted upon the rod S1 and extends upwardly; therefrom a shorl` distance. and its upper end is threaded upon the'oscilla'- ingr rod 110.1'he rorl'110 also passing" through the 111 being pivoted above and member 112 henig pivoted below oscillating. rod 110, as

represents the r'st operation; Fig. 8 'the second; and Fig. 9 the third. The travel of one pair of the 'thread carriers'is diagrammatically represented in plan view in Fig. 14, where I indicates a movement of the thread carriers to the front; II a movement to the right; III a movement to the center; IV a movement to the right; V a movement to the front; VI a movement to the left; VII a movement toward the center, and

VIII a movement to the left.' The two inclosed ovals indicate the position -of the needles, around which the thread make this travel.

In Fig. 15 is a diagrammatic, representa tion of the stitches or loops of thread so laid by the thread carriers around these needles. In the center these threads have a closed loop made by the knitting mechanism as shown. This closed loop is formed at the central position where the converging thread carrier movement VIII and I approach nearest the converging thread carrier movements IV and V.

In Fig. 8 the two thread carriers 103 and 104 meet at their lower ends and this is the innermost point in their oscillatory motion. In Fig. 7 the lower end of the thread carrier 103 moves to the front and the lower end of the thread carrier 104 moves to the rear.

'In Fig. 8 the thread carriers 103 and 104 return to their closed or central position, and in Fig. 9 the lower end of the thread carriers move to the position shown in Fig. 7.

It being understood that each set of the side thread guides feed threads or yarns to the needles of one side only and that these two lsides are connected or joined together tt the ends by the end thread guides as folows:

The movement of one pair of end` thread guides is shown at the right-handsidc of Fig. 15, from which figure it will be seen that the threads which arecontrolled by the end thread guides are manipulated so as to be acted upon by the needles of both sets, thus knitting together the two sides of the fabric at the ends thereof.

The threads passing smoothly over the rounded edge of the spreader bars 105 and 106, extend to and throufrh the thread carriers to the needles.

The needle move; .nt will be now d'escribed in general te There are two k of needle movements, one is an alterna pward and downward movement ina vertical lane, and the other is an alternate horizcntai3 movement in said plane. i The front cam shaft 6 in rotating turns with it the cams 12 and 13, which impart a reciprocating movement to the shoes 14 and 15. The push- rods 16 and 17 which extend up from said shoes, are connected at their upper ends (Fig. 13) Withthe needle-lift ing bars 72. Thus the needles have a regular reciprocating vertical movement by eyes of the reason of the mounting of the hubs of the 'needles on the needle-lifting bar, as represented in Fig. 7, where it is seen that there aretwo connected needle-lifting bars and their accessories, one for the front, and one for the back of the machine.

The horizontal reciprocation of the needle bars 62 and 63 and of the needle-lifting bars therewith is caused by the cam 33 on lthe lefthand end of the rear cam shaft 7, as shown in Fig. 1. This cam shaft gives a movement to the rocker bar 35 which is pivotally mounted on the bracket 34, and this rocking movement is communicated to the needle ar 62 and-through theroclzing lever 66 to yneedle plate 63, back and forth in each rotation of said cam shaft, it being understood that as the front needle bar moves to the right the rear needle plate will move to the left and vice versa. The length of each horizontal reciprocation is equal to the distance between'two adj acentneedles.

As the threads are knitted into the fabric I tape space 69 and is subjected to the stitchtightening mechanism, as shown in Fig'. 7, and presently described, and are wound upon the take-up roll or drum (not shown).

The kind of fabric made by this machine cannot be suliciently close and iirm cn a knitting machine (in Vthe first or best quality of goods) without the use of a suitable stitch-tightening device. In my machine there is provided a stitch-tightening mechanism which draws each row of stitches as they are formed and are leaving the needles by taking up the slack of the thread. By a combination of cam movements the loops or stitches are closed to any degree required after leaving the needles, and thus the fabric can be made much tighter than has been heretofore possible in vmachinery of this class.- On each rotation of a front cam shaft, the rod' 40 ispulled toward the rear of the machine and the threads which pass yin front of the two xed .rods and 48 IIE :lessees A are drawnslightly toward the reer by the i^od.40, operated bythe lever 36 and the cam 24, as already described.

The tension o the spiral springs on the ends of the strap 125 maybe adjusted 'by ineens of holes in said strap.

ln the knitting process the needle latches nre closed by the descent of the needle stein through the thread loopwhich hes justj been laid on the needle by the thread carriers, and when the loop has been knit into the fabric andthe needleyhas been freed therefrom the rise. of the needle causes the threads from the thread carriers to engage the needle latch and move it downward into its 'open position, asseen in Figs. I and 9.

lhe oscillating ymovement of the -side thread carri( is` caused by the cams 1S and 19 on the iii-ont cani shaft 6, which earn operating the @ein shoes 20 and 2l canse the puse-rods and alternately to move up and down. ln moving up this push-rod opens the lezytongs (made up oli' the pivotallv connected bars T7, SO, 82 and 83,) thus opening the spreeder bars to their Widest extent, but in moving down the push-rods and close the lazy tongs.

'The oseillating movement. of the end thread (terriersy is caused by the cams 2T and which cams operating shoes 29 and 30 causes Vthe push-rods 3l and to move alternately up and down, thus rocking the hell crank l ver 199 and vibrating the rod llo to open and close the end guides as heee-I 1 toiore described.

The neriodicel rise and descent of the needles nre caused by the cams l2 and. l

of the front cem shaft 8 which give a. vertical reciprocating movement by ineens of the cani shoes le and l5 on seid coins, re-

spectively. and this 1i veillent communito bv the comb hars T3 and coverinrf strips Tel, Thus the needles rise and Vtall periodically in the ordinary welldnown manner.

lt has been stated that the front com shaft fj rotates twice While the rear @ein shalt 7 geared thereto7 rotates once. is also parent that seid shafts rotate in opposite directions. ltn'ill he seen from Fig. @that cams i?? und are oi such coniiguration peripliernlly thaty push-rods El and 32 will have two successive upward movements and then two successive downward movements during each revolution .of shaft 7. t will also be seen from Q that cams i8 and 19 are formed, that push-rods 22 end 23 will move up and down once during each rev/olstion of shaft t5, end that cams l2 and 13 will move rods lo and 17 np and down .once for ezich' revolution ofslieft 6.

The stitch-tihtening device copemt-es with the friction tolte-up rolls 53 and 55.

lili? lill band to travel from Said Ibeing tight ont shaftwhich turns A takep roll receiving the wel pulley 46 on the front cam shaft 6 causes va 44 and 45 to the ulley 48. The pulley 48, e shaft 49, rotates said with its worm 50 to operate the worm gear 52. This worm gear vbeing fast on the shaft on which the rear take-up roll 53 is secured, turns said roll, which in turn rotates roll 55 through its connected gearings. The knit fabric is drawn by these rolls and passes to the take-up reel or drum, not shown.

The stitch tightener operates after each row of stitches has been formed. The cam 24 on shaft 6 is-so timed with relation to the cams 12 and 13 on said shaft and also with the pullev 46 on shaft 6 and the pulley 48 on the s aft 49, that the stitch is tightened when the needles reach their lowest position.

A variety of other stitches can be made by changing the movements'and relations of the needles with respect to the oscillating thread carriers and thus the pattern ofthe knit fabric can be changed or varied as desired.

The take-up diam, not shown, operated in any desired manner, but is preferably operatedvas shown and described in my application filed February 7, 1913, Se. No. 746,828.

It will be understood that while I have described and shown my preferred form of construction and operation, I do not limit myself thereto vbut may vary the same if desired.
