chine thus r'ar is well known and needs no detailed description herein.

In the preferred form of embodiment of In invention I provide the needle-cylinder witli five sets of needles 16, 17, 18, 19, and-20 and arrange said needles in the relation shown in Figs. 8 and 11. v Thelatches of the needles 17 and 18 are longer than those of the needles 16, the latches of the needles 19 and 20 are longer than those of the needles 17 and 18, and the butts of the needles 18 and 20 are shorter than those of the needles 16; 17, and 19. j The cam-cylinder 6' carries the usual latchguard 21, in which are formed two threadguiding eyes 22. and 23. The eye 23 is arranged adjacent to the stitch-cams 11 and 12, and the eye 22 is arranged adjacent to a stitch-cam 24. This stitch-cam 24 is slidis, a osition to act' upon the butts of all the need es. The head 27 is provided with a projectingpinBO, bearing against a cam-surface 31 on the bracket 26, to the end that when the head 27 is turned in one direction to bring the in 30 into engagement with the outer face of the bracket 26 the cam 24 will be moved out of the canr-cylinder away from the butts of the needles, and when the head27 is turned in the reverse direction the spring 28 will be permitted to move the cam 24 back into the'caIn-cylinder.

9e Formed onthe stitch-camsll and 12 are raising-cams 32 and 33, arranged in advance of said stitchcams, respectively. These earns 32 and 33 are adapted to raise the needles, so that all their latches will escape their engaged loops of thread.

, Arranged in advance of the stitch-cam 24 or in rear of the stitch-cam 12 are two vertically-movable raising- cams 34 and 35, the cam 34 being arranged to act only upon the long butts of the needles 16, 17, and 19 and the 'cam 35 being arranged to act upon all of the needles. The cam 34 is mounted on a vertically-movable head 36, which is slidingly fitted to the cam-cylinder 6 and is adapted ICC to be moved to brin the cam 34 to the three positions shown in ig; 10, the full lines indicating the up position, the dash-lines indicating the down position, and the dotted lines indicatin the intermediate position. By shifting the cam 34 to these different positions at predetermined intervals the needles 17 and 19 may be actuated to vary and control the design of the knitted fabric, as will be hereinafter fully explained. a Secured to the head 36 is a bracket 37, from which rises a pin 38, provided with an encircling spring 39, which bearing against the bracket 37 and an arm 40, extending from a bracket 41, mounted on the camcylinder, tends normally to depress the head '36. The-bracket 37 is provided with a pin 42, and the bracket 41 is provided with a pivoted arm 43, adapted to be moved into and out of the path traversed by the pin 42 when the head 36 is raised and lowered. When the arm 43 occupies a position out of the path of the pin 42, the spring 39 will de- I press the head 36 and cam 34 to the down po- 'sition, and when the arm 43 is moved into the path-of thepin 42 thapin 42 will engage the arm 43 and stop the downward movement of the head 36 to bring the cam 34 to rest at the intermediate position.

Prior to commencing the knitting of the leg portion ofa stocking the arm 43 is moved from the path of the pin 42 to permit the cam 34 to be moved to the up and down positions, and prior to commencing the knitting 3 5 of'the foot portion of the stocking the arm 43 is moved into the path of the pin 42 to limit the downward movement of the cam 34 to' the intermediate positions 7 The cam 34 is moved to its up and down 0 positions at substantially the same point in its path of rotation about the needle cylinder, and the preferred means to this end is as follows Mounted on a shaft 44 is an arm 45, the lower end of which is pro- 5 vided with a pin 46, adapted to engage a cam 47 on the main shaft 10. The upper end of the arm is arranged adjacent to the free end of an arm 48, projecting loosely from a stud-shaft 49 on a bracket 50, which is se- 50 cured to the bed-plate 1.

shaft 49 and having one of its ends engaged with a head 51 thereon is a spring 52, the other end of which is engaged with'the arm 48 to maintain it in engagement with the arm 45 and alsoto maintain the pin 46 on the arm 45 inengagefnent with the cam 47, whereby when the shaft 10 is rotated the arms 45 and 48'will be rocked in unison. The arm 48 carries a pawl 53 in engagement 6: with a ratchet-wheel 54, which is-loosely mounted on the shaft 49, whereby when the arm 48 is rocked the ratchet-wheel 54 will be intermittently rotated. A suitable stoppawl 55 is mounted on the bracket 56 to en- 6 5 gage and prevent the backward movement Encircling. the

of the wheel 54. Loosely mounted on the shaft 49 and secured to the wheel 54 to be moved thereby is a wheel 56, which is provided in its periphery with notches 57, which aro arranged to control certain portions of the design in the fabric, as will hereinafter appear. Slidingly fitted to the bracket 50 is a horizontally-reciproeative pin 58, which is provided with an arm 59, projecting througha slot 60 in the bracket 56 to a position adjacent to the periphery of the wheel 56. The pin. 58 is held normally inward that is, toward the cam-cylinderby the action of a spring 61, encircling the pin 58 and bearing against the bracket 50 and a collar 62 on the said pin. .The outer end of the pin 58 is provided witha rotatable head 63, which taking against the bracket 50 limits the in-.

Projecting war'd movement of said pin. from the head 63'and into the slot 60 is a pin 64, which when the pin 58 is moved outwardly and the head 63 turned is adapted to engage the bracket 50 to maintain the pin '58 in the outer position against the action of the spring 61. One side of each notch 57 is beveled, as shown, andwhen the pin 64 is in register with the slot 60 the arm 59 is adapted to bear against the periphery of the wheel 56 to the end that as thewheel 54 and therewith'the wheel 56 are intermittently rotated the arm 59 will enter the notches 57 succes sively to permit the spring 61 to move the pin 58 to the inner position, and the beveled sides of the notches will move the arm 59 and pin 58 to the outer position at certain predetermined intervals, according to the number and arrangement of said notches. When the pin 58 is moved inwardly, its inner end occupies a position in the path traversed by a toothed wheel 65, and when the pin 58 is moved outwardl its inner end is out of the path of said w eel. This wheel 65 is carried by the cam cylinder 6 and is mounted on the outer end of an intermittently-rotatable shaft 66, which is journaled in the bracket 41, hereinbefore referred to, whereby when the pin 58 occupies the inner position the wheel 65 will engage said pin and move the shaft 66 one step at each revolution of the cam-cylinder, and when the pin 58 occupies the outer position the wheel 65 will be unaffected thereby. The inner end of the shaft 66 carries an elongated block 67, arranged directly below the bracket 37, and the'wheel 65 is provided with four teeth. Thus it will be seen that as the wheel. 65 is turned step by step the block 67 will be brought to vertical and horizontal positions in alternate succession and that when the block is brought to the .vertical position it will engage the bracket 37 and raisethe cam 34 to'the up position against the action of the spring 39, and when the .block 67 is brought to the horizontal position it will escape the bracket 37 and permit the spring IOK 39 to return the cam 34 to eitherthe inter mediate or down position, according to the position of the arm 43; The shaft 66 is provided with depressions 68, corresponding with the teeth of the wheel 65, and arranged within an opening in the bracket 41 is a ball 69, which is depressed by the action of a spring 70. The ball '69 is adapted to register with-the depressions 68 to maintain the 7 1o shaft 66 in the positions to which it is moved yielding to by'the Wheel 65, the spring70 permit the rotation of theishaftj The cam 35,. hereinbefore mentioned, is mounted on a vertically-movable head 71,

which is slidingly fitted to the cam-cylinder 6. This-head 71 is provided with a spring-- 2 5 pies the raised position all the needles are I raisedtheneby to cause'the latches of the needles 16, 17, and 1-8 to escape their engaged loops of thread. By changing the? position of the cam certain parts of the' 30 design ,of the knitted fabric may be con trolled, as will be hereinafter explained.

The needle cylinder 2 is rovided with sinkers or web-holders 75 of we l-known type, which are held normally inward by the action 3 5 of a spring-band 76 and operate 1n the usual manner to engage the knitted fabric and prevent its upward movement with the needles during the knitting operation. These sinkers are moved out of action where the'oppo- 4o sitely-disposed stitch-cams 11 and 12 and sing stitch-cam 24 passes the needles by two sinker-cams 77 and 78, respectively, which are carried by the ring 79, which is rotatably mounted on the needle-cylinder 2 and connected with the cam-cylinder 6 to ro-I tate therewith and operate the sinkers in the usual well-known manner.' The cam. 77 is fixed to the ring 79, and the cam 78 is provided with rojecting screws 80, winch-ex: 5o tend through slots formed in the ring 79 and a bracket 81, secured to said ring. -These slots form guideways to permit thecam 78 to be raised to the inoperative position or de ressed to the o erative position. Rotata 5 5 Ely mounted in the bracket 81 is a rock-shaft 82, havingon its inner end a cam-head 83, which when the shaft 82 is rockedin one direction is adapted to engage the to of the cam 78 and force said camdownto t e oper- 6o ative position against the action of the s ringband 76-and when the shaft 82 is roc ed in the reverse direction will esca ethe cam 7 8 and ermit the butts of the sin 'ers 75, under the influence of the spring-band 76,,to raise thecam 78 to the inoperative position. The

er 6 to maintainthe cam 35' outer end of the shaft 82 is provided with a suitable head 84, bymeans of which the shaft 82 may be rocked.

In Fig. 8 I have indicated by'aline 00 00 the top of the web or plane wherethe stitches are formed.

' The needles 16 are arranged around the entire cylinder. The needles 19 and 20 are arranged around that portion of the cylinder on which the front of. the stocking is produced, and the needles 1-7 and 18a-re arranged around that portion of the cylinder on'which" the back and sole of the stocking are produced.

Assumlng that a white thread 85 i's being delivered to the'needl'es' through the eye 23 and a black thread 86 through the eye 22, the

operation of the machine is as follows: As the cam-cylinder rotates to produce the leg and foot portions of a stocking the stitch-cam 12 acts-upon. all the needles at all times to producestitches in the usual manner, and the stitch-cam 24 acts upon all the'needles and produces stitches-by only those needles which previously to being acted uponthereby have eenraised to clear their latches of their engaged loops of thread. It will be seen that .:I-the needles having their latches engaged with their loops of thread when they meetthe cam 24 will merely draw downthe black thread 86 without knitting, and after being raisedby the cam 33 to clear their latches of the thread they will be acted upon by the cam 12 to engage the white thread 85 to produce stitches thereby and at the same time to cast off their superposed loops of black thread. Thus the needles having their latches engaged with their loop's when they meet the cam24 and clear when they meet the cam 12 will each knit a chain of whitev stitches down the face of the fabric to produce a longitudinal stripe in the stocking, and the other needles having their latches free upon meeting both cams 24 and 12 will knit alternate transverse rows of black and white stitches.

By the employmentof my invention any number of stripes the sole of the stocking. The needles 19 are operated to produce the longitudinal stri es at certain intervals down the front of the leg portion and the top of the foot portion of the stocking, and the needles 17 areoperated intervals down the back of the eg portion of the stocking and to eliminate said stri es from the sole of the stocking. The nee les 20 are operated to produce the continuous longitudinal stripes down the front of the leg portion and the top of the foot-portion of the to produce the longitudinal stri es at certain stocking, and the needles18 are operated. to produce the continuous longitudinal stripes down the back of the leg ortion of the stocking and to eliminate-sald stripes from the sole of the stocking.

During the knitting of the leg portion of the stocking the'parts occupy the position shown in" the drawings and the cam 34 is moved to the up and down positlons at certainpredetermined intervals, according to the number and arrangement of the. notches in the wheel 56, as previously explained. The cam 14raises the needles snfliciently to cause the latches of the needles 1.6 to clear their engaged loops of thread. Therefore so long as the latches of the other needles are permitted to remain in their loops when they meet the cam 24 they will not knit the black thread 86, but will knit a chain of white stitches down theface of the fabric toproduce a white stripe. It will be seen that when the cam 34 is in the down position the needles 17 and 19 will be unaffected thereby and will knit the longitudinal white stripe, and when the cam 34 is in the up position the needles 17 and 19 will be raised thereby to clear their latches of their loops and cease to knit the white stripes and knit the-black thread into thefabric similarly to the-needles 16. Thus the white stripe is pro ducedat cer tain intervals, according to the m anipulation of-the cam- 34. During theknitting of the leg portion of the stocking the cam 35 remains down and the needles 18 and 20, being unaffected thereby and having their latches "engaged with their loops upon meeting the cam 24, knit continuous longitudinal white stripes.

the

are moved into andoutof action in the li su al well kuo Wn Iranner, the thread 85 being knitted: into the fabric and the thread 86, due to its'position away from the cams 11 and 12, moving idly back and forth with the reciprocation of the cam-cylinder. During the knitting of the heel the stitch-cams 11- and 12 operate the needles and, the can't-s 32 and 33 raise the needles, so that all their latches will escape their engaged loops of thread. After eel has been completed the needles in the back half of the cylinder are movedback into action, the head 63 is turned to bring the pin64 into register'with the slot and. permit the pin 58 to return to the path of the wheel 65, the head 27 is turned to project the stitch-cam 24 back into the cam-cylinder, the cam 35 is raised by hand to the up positio n, wherein it is high enough to clear all the latches of all the needles engaging it except the needles 19 and 20, the arm 43 is moved to a position beneath the pin 42 to limit the downward movement of the cam 34 to the intermediate position, the sinker-cam 78 is moved back intoaction, and the cam-cylinder is rotated to knit the foot portion of the stocking.

During the knittin 'of the foot portion of the stocking the nee les 20,and 19 are not fraised by the cam 35 to clear their latches of their engaged loops of thread, and consequ ently they knit the longitudinal stripes continuously and at certain intervals, respectively, down the top of the foot portion of the stocking, just as they did during the knitting of the leg portion of the stocking, owing to the manipulation of the cam 34 but the needles 18 in the back half of the cylinder are raised by the cam 35 to clear their latches of their engaged loops and thereby cause them to knit the black thread into the fabric similarly to the needles 16, and the needles 17, also in the back half,-are-alw ays raised by the cam 34-irrespective of its up or inter-mediate position to clear their latches of their engaged loops of thread, and thereby cause them toknit the black thread into the fabric similarly to-the needles-16. Thus it will be see-n that the design being produced in the stocking is continred down the top of the foot portion thereof and eliminated from the bottom or sole thereof, all the needles inthe back half of the cylinder 2 being caused to engageand knit both threads 85 and 86 into the fabric during-the knitting of the foot. After the com letion of the foot the toe is produced simi arly to the'heel, whereupon the parts are setback to the position shown in the drawings for a succeeding operation.

By changing the number and positions of the needles 17, 18, 19, and 20 and by changing the number and positions ofthe notches in the wheel 56 a great variety of designs may be produced down the front and back of a stocking and eliminated from the sole thereof.
