To all whom it may concern:

Be it known that I, Josnrn WHEELER, a subject of the King of Great Britain, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Circular Inde endent-Needle Knitting-Machine, of which t e following is a specification.

My invention relates to a novel construction of a knitting-machine; and it consists of means for raisin and lowering any desired number of tuckmg-carns either simultaneousl or independently of each other, so as to pro uce knitted fabrics having lace efiects.

It also broadly consists of means for adjusting the draw or stitch cams relatively to each other and also of means whereby the needles may be easily inserted and also removed from the needle-cylinder at pleasure. It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Referring to the drawings, 1 designates the frame of the machine, in which is journaled the shaft .2, having loosely mounted thereon a ratchet-wheel 3 and a sprocketwheel 4, the latter being keyed or otherwise secured to said shaft and is provided with a sprocket-chain 5, which has secured thereon a stud 6, adapted to operate the arm 7, so as to rock the shaft 8, and consequently the arm 9, secured thereto, and thus lmpart motion to the stop-rod 1 0.

. The ratchet-wheel 3 is provided with openings 11-, in-which are inserted the studs 12 and 13, and also with openings 14, ada ted to receive studs 15, the object of all of w ich is hereinafter described. 1

Secured to the shaft 2 is a gear-wheel 73, which meshes with the ear-wheel 74, secured to'a shaft 75, on w 'ch is a drum 76, provided with spurs 77 for a purpose heremafter described.

' The shaft 2 has loosely fitted thereon the ratchet-wheel 16 which has secured thereto the s rocket wheel 17, around which is passe the pattern-chain 18, which is pro vided with studs 19, 20, 21, and 22. Secured to the shaft 51, journaled in' the frame 1, are the arms and 52, the latter being in contact with the awl 53, pivoted at 54 to the slide55, guided to which a reciprocating motion is imparted by the lever 56, 'fulcrumed at 57 in the frame 1. The lever 56 has a rocking motion 1marted thereto by the eccentric ring 58, (see i 3,) which may be secu'redto the camin the frames 1 and v vided with a s lever 56 is held in contact with the rim 58 by a spring 59, one end of which is secure to the lever 56, while its opposite end is secured to a convenient .fixed point in the frame 1. The slide 55 is provided with a pawl 60, which engages with the ratchet-wheel 3, so as to impart motion thereto. the frame 1 is a lever 62, which is operated by the pattern-chain 18. Pivoted to the lever 62 is a bar 63, which engages at certain times with a stud 64 on the ratchet-wheel 3, the lever 62 being held in its normal position by the spring 65.

- Guided in the frame 1 and '25, which actuate, respectively, the bellcrank levers 26, 27, and 28, which are ivoted at 60 in the frame 1 and are provi ed, respectively, with screws 29, 30, and 31, which are adjustably fitted therein.

Guided inthe frame 1 are the lungers 32, 33, and 34, whose outer ends a u-t against the screws 29, 30, and 31, respectively, it -being noted that each of said plungers is proring 35 for a purpose hereinafter describe The cam-cylinder 39 is provided with starwheels 36, 37, and 38 and each of said wheels is provided with a cam 40, u on which tests a slide 41, connected with a ug 42, which is placed in its res ective opening 43 in the camcylinder 39, it being noted that each lug 42 has secured thereto a tucking-cam 43 and is raised and lowered by-its cam 40. In the present instance there are three tuckingcams employed, although any desired number of such cams may be used. The cam-cylinder 39 is provided with drawcams 44, each of which is secured to a block 45, fitted in the cam-cylinder 39, so as to be vertically adjusted therein, said blocks 45 being provided with adjusting screws 46 and j am-nuts 47, there being as many draw-cams employed as there are tucking-cams used. The draw-cams are held in their ad 'usted positions by'th'e lever 48, fulcrume at 49 in the cam-cylinder 39. The lever 48 is for the,

purpose of lowering the stitch-cams 44, so as to form a slack or loose stitch at the end of the stocking near the foot and denotes where the foot of the stocking is to be knitted on, it being understood that a certain amount of plain knitting follows this slack, so as to allow or raveling and trimmin Each cam 40 is provife'd'with sockets 66, adapted to receive at certain times a ball 67, which is located in a socket 68 in the camcylinder 39 and is pushed forward by a spring 69 for a purpose hereinafter described. The cam-cylinder 39'is provided with plugs 70, adapted to open and close the passages 71 in the run 72 to permit needles to be either Y inserted in the needle-rylinder 85 or removed therefrom, as desire thumb-piece,

and 71 designates a spring for the plug 70.

Journaled in the frame 1 are Fulcrumed at 61 in I are the bars 23, 24, I

designates a take-up rollers 78, to which motion may be imlparted from the fixed pulley 81 by the be t 84. n

The cam-cylinder 39 may be driven in the usual manner, as illustrated in Fig. 10, and which consists of the bevel gear-wheels 79 and 80, the latter being mounted on the main driving-shaft 80, journaled in the frame 1 and provided with the fast and loose pulleys 81 and 82, respectively, and a driving-belt 83.

Motion may be imparted to the take-up rollers 78 by a belt 84, ledfrom the pulley 81 to the pulley 81, fast on the shaft ofone of the feed-rollers 78.

85 designates the needle-cylinder, which is of sufficient length to receive the needles, which in the present instance are of three different lengths.

86 designates a needle with short latch 87, and 88 designates a needle with a long latch 89, it being understood that there areas many different length of needles as there are tucking-cams employed and that said needles are provided with butts 90, as usual.

I T e needles 91 in the modification shown in Fig. 30 are longer than the needles 86 and 88, while the needles 92 are longer than the needles 91, which two latter sets consist of long and short latches similar to those seen in Fig. 25.

The short-latch needles take a stitch every revolution of the machine, and the longlatch needles take a stitch only when the tucking-cams are raised, and when the said tucking-cams are lowered the long latch needles gather in the threads, thus forming the ordinary tuck-stitch.

93 designates the yarn, which is fed to the needles in the cylinder 85 in the usual man ner.

The operation is as follows: The needles 86, 88, 91, and 92 are placed in the needlecylinder 85, arranged in three sets according to their lengths, one set working with each of the three sets of cam-grooves and are so arranged therein as to goduce a fabric of predetermined design. or instance, they may be laced in groups, as at d and e in Fig. 29, and in alternate needle-grooves, as at and when desired several grooves 94 may e leftdevoid of needles, the arran ement depending upon the design of the fa ric. The lugs 19, 20, 21, and 22 are placed on'the patternchain '18 in such positions relatively to each other that they work in harmony with the IIO needles. The yarn '93 is fed to the needles in the usual manner. The number of reeds employed depends entirely upon the number of series or draw and tucking cams employed, it being apparent that the greater the number of series of said cams the larger the number of feeds which will be necessary to produce the desired result. --'When the machine is started, the cam-cylinder 39 is rotated, and n of the studs, 15 in the with. it the eccentric ring 58, andimparts a rockin motion to the lever 56, which causes the slide55 to reciprocate, so as to move the pa'wls 53 and 60 to and fro. Assuming the ratchet-wheel 16 to have rotated by reason of from its engagement with the stop 12, which will permit the pawl 60 to drop and engage the ratchet-wheel 3 and move the same into the positionseen in Fig. 12, at which time the stud 13 will have enga ed the lever 10 and caused the pawl 60 to be released from its engagement with the ratchet-wheel 3. On the further rotation of the ratchet-wheel 16 the lug 22 on the chain 18 will engage the lever 62. This causes the lever 62 to turn onits fulcrum 61, so as to depress the bar 63, which by reason of its contact with the stud 64 causes the ratchet-whee]. 3 to rotate sufficiently to remove the stud 13 from beneath the lever 10. (Compare Figs. 12-and 13.) When the stud 12 leaves the lever 10, the latter drops and permits the pawl 60 to engage with the ratchet-wheel 3 and impartmotion thereto. a

When the ratchet-wheel 3 is at rest, the

lace fabric is being made, and when the. ratchet-wheel 3 is rotatin the plain fabric is being made. As the rate et-wheel 3 rotates it throws the pawl 53 out of action by means a holes 14, said studs engagin the lever 50, thus throwing out of action t e ratchet-wheel 16 and bringing the pattern-chain to rest. When the parts are in the position seen in Fig. 11, the lug 6 on the length chain 5 causes the ratchet-wheel 3 to rotate, bringing it to the position seen in Fig. 12. The lug 22 on a chain 18 then raises the lever 62, which depresses the stud 64 on the ratchet 3' and causes said ratchet-wheel 3 to rotate, as seen in Fig. 13, said wheels continuing to rotate until brought to rest. This stopping of the ratchet-wheel 3 is caused by the stud 12 engaging the stop-rod 10, which latter causes the awl to be disengaged from the ratchct-wheel 3, at which time the parts Will be in the position as seen in Fig. 11. When a stud 22' has left the lever 62, the latter is returned to its normal position, as in in Fig. 12, by the spring 65. The ratchetwheel 3in turning causes the studs 15 ,which are inserted in the ratchet-wheel 3, to engage the lever 50 and turn the shaft 51, (see Figs. 8 and 9,) thereby causing the lever 52 to remove the pawl 53 from its engagement with the ratchet-wheel 16, so as to cause the latter to remain stationary until the last stud 15 leaves the lever 50, when the latter drops and permits the pawl 53 to again engage the ratchet wheel 16 and turn t e same.

It is obvious that'the number of studs 15 inserted'in the wheel 3 determines the durationof the stationary period in each revolution of the wheel 16, and the number of studs 15 also denotes the len th of the plain section of the fabric. uring any desired period in the plain stitch the slack course.

above described may be made in any part of the plain section of the fabric, which latter is regulated by the studs 15.

The ratchet-wheel 16 imparts motion to the sprocket-wheels 1 7, and consequently to the pattern-chain 18, and as these wheels and chain move as one it is apparent that when the wheel 16 comes to a standstill the chain 18 will likewise come to a stop.

When a stud 19 is brought under the bar 23, (see Fig, 2,) it lifts said bar and turns the lever 26 on its fulcrum 60, thereby causing the screw 29 to advance the plunger 32 so that. the latter is brought in the path of the star-wheel 41, which is in alinement therewith, so that said wheel 41 has a quarter of a revolution impartedthereto by reason of its contact with the plunger 32 due to the. revolution of the cam-cylinder 39.

When the cams 43 are in the positions seen in Fig. 14, the short-latch needles are raised sufficiently to bring their latches 87 above the yarn 93, as seen in Fig. 26, so that when said needles are lowered they draw said yarn through the loops thereon and produce plain knitting. The needles 88 are also lifted by the cams 43, but being provided with long latches 89 the latter do not pass above the yarn 93, (see Fig. 26,) and consequently retain said yarn under their hooks, which receive one additional strand at each revolu: tion of the cam-cylinder 39. When the uppermost -cam 43 is in the position seen in Fig. 14, the cam 40 is in the position seen in Fig. 20, so that when the star-wheel 36 is brought a ainst the plunger 32 it is gradually turned on its axis during the rotation of the cam-cylinder 39, which carries said star-wheel. In Fig. 20 the star-wheel 36 is represented as just broughtin contact with the plunger 32, while in Fig. 19 said starwheel 36 is in a position occupies when a partial rotation is imparted thereto, its axis 95 being now almost directly above the plunger 32 and when said wheel leaves the plunger 32 it is in the position seen in Fig. 21, it having had a quarter of a revolution imparted thereto by its contact with said plunger ride up this cam 43 in its elevated position said needles are raised sufiiciently to bring their latches 89 above the yarn 93, as seen in Fig. 27, so that when said needles are lowered they draw the several strands of yarn 93 through the loops 96 thereon, as seen in Fig. 28, thereby casting ofl? the tuck-stitches and producin the star effect at g in the fabric 97. (Seen in igs. 32 and 33.)

When a cam 40 is in the position seen in Fig. 20, said cam is prevented from improper rotation by reason of its position relatively to the slide 41; but when said cams 40 are in the position seen in Fi 21 thesame might turn beyond the desire point. So to avoid this the ball-and-socket device seen in Fig. 18 is employed, it being understood that a ball 67 is forced into a socket 68 when a starwheel is turning.

- When a stud 19 leaves the bar 23, the latter drops and turns the lever 26, Whereu on the screw 29 releases its pressure on the p unger 32 and permits it to return to its normal position, which is one similar to that of the plunger 33 in Fig. 2, it being apparent that when said plungers 32, 33, and 34 are in their normal positions they are out of the path of their respective star-wheels 36, 3-7, and 38, so that when a cam 43 is either in its uppermost or its lowermost .position it remains so until its plunger is again advanced, so as to turn its star-wheel.

In Fig. 4 the plun er 32 is in its normal position and permits t e star-wheel 36 to pass without contacting therewith, thereby permitting its cam 40 to remain in the position in which it was left when last turned by the star-wheel 36 and remain in this position until again turned by the star-wheel36 and plunger 32, as hereinbefore described.

The object of the plungers 33 and 34 and the star- wheels 37 and 38 being to raise and lower their respective cams 43 in the same manner as described in connection with the plunger 32 and star-wheel 36 and for a similar purpose, it is deemed unnecessary to describe the operation of these, since it isv similar to that hereinbefore described.

It is to be understood that the several cams 43 may be raised and lowered simultaneously or else independently of each other according .torequirements.

When the fabric 97 is being drawn between the take-up rollers 78, it causes the drum 76 to rotate by its contact therewith, and thus impart motion to the gear-wheels 73 and 74, so as to turn the sprocket-wheel 4 and operate the chain 5, so that the link 6 thereon may be'brought in contact with the lever 7,

so as to rock the shaft 8, and thereby cause the arm 9 to remove the sto rod 10 from the stud 13 and permit the paw to engage the ratchet-wheel 3, and thus rotate the same, said lug 6 being brought in contact with the arm 7 when a predetermined length of the fabric is begun and continuing to travel until said length is completed, when said. lug is again brought in contact with the arm 7, so

60 to, again 0 crate the ratchet-wheel 3, as hereinbefore escribed. By the provision of three separate camgrooves each having an automaticall -ad-'- vent the making of a variable pattern unit sufficiently wide to be very noticeablethat is to say, I can make a diagonal square, such as G in Fig. 33, having eight gathered (tucked) spots. By the use of two variable cams I could produce a figure of this kind having only four such spots, which would scarcely be noticeable in a garment such asa stocking.

It will be evident that various chaes may be made by those skilled intheart which will come within the scope of'my invention, and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.
