FEEDING MECHANISM FOR CIRCULAR-KNITTING MACHINES.

SPECIFCATIO forming part of Letters Patent o. 455,018, dated June 30, 1891. Application tiled July 1,1890. Serial No. 357,340. (No model.)

To all whom it may concern:

Be it known that I, LEON C. HUSE, of Laconia, county of Belknap, State of New Hampshire, have invented an Improvement in Feeding Mechanism for Circular- Knitting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures 011 the drawings representing like parts.

1Q This invention relates to circular-knitting machines, and has for its object to provide mechanism, as will be described, by which a second or independent thread may be knitted to form a double thickness of re-enforce for I5 the garment at those parts or places most subjected to wear-as, for instance, at the knees of stockings.

My invention in a circular-knitting machine therefore consists in the combination, with zo the needle-cylinder to contain needles, the

cam-ring, a stationary thread-guide, a movable thread-guide and itsl carrier, of a disk pivoted to the cam-ring and provided with one or more cams, an actuating device for the z 5 movable carrier operated bythe said cams to eiTect the movement of the movable threadguide carrier, levers c3 c4, provided with posts to rotate the disk, a pattern chain, and a pivoted rod connected to the said levers and acted upon by the pattern-chain to move the said levers, substantially as will be described.

Other features of my invention will be pointed out in the claims at the end of this specification.

3 5 Figure l is a side elevation of a suicient portion of a knitting-machine embodying my invention to enable it to be understood. Fig. 2 is a top View or plan of the machine shown in Fig. l; Fig. 3, a detail in elevation of the operating-cam; Fig. 4, a sectional detail of the cam shown in Fig. 3 on line Qc looking toward the right; and Fig. 5, a section of the cam shown in Fig. 3 on line .fr 11:, looking toward the left. l The bed plate a, having the depending bracket a', the pattern-ring d2, pivoted thereto and provided with the pattern-chain a3, the rachet-wheel a4 to move said pattern ring and chain, the pawl a5 and gears a6 a7, rotated from 5o the cam-ring as to operate the said pawl, the cam cylinder or ring a8, carrying the cams for operating the cylinder-needles, (not herein shown,) the bevel-gear a, secured to the under side of the cam-ring, the dial-plate am, the spindle 0.12, upon which the said plate is mounted, and the yoke a, secured to. the cam-ring as, are and may be of usual construction, such as commonly employed on circularknitting machines.

In accordance with my invention the ma- 6o chine is provided with two thread-guides bb', shown in Fig. 1 as secured to two metal bars or carriers b2 b3, extended through suitable guideways between two plates b4 b5, fastened together, as by screws be, and supported by a .bracket bx, fastened to the cam ring or cylinder as, as by a screw h2o, one of the said carriers, as b2, being stationary and the other movable in its guideway, as will be described. The carrier b2 is fixed so that its thread-guide 7o b is in position to have its thread engaged by the cylinder-needles. The movable carrier b3 has secured to it, as herein shown, a plate or bar b1", provided with a slot or opening, through which is extended an actuating device (shown as a spring-actuated lever Z312, pivoted at its lower end, asat Z913, to a boss or projection 514 on the cam-ring 0,8.) The springactuated lever Z212 is provided with a stud or projecting arm or rod 1215, which is engaged 8o and acted upon by cams Z216, preferably forming partof a ring detachably secured on the inner face of a disk Z917, as shown, by screws Z218, diametrically opposite one another, (see Fig. 2,) the said screws being extended through slots b19 in' the said disks. The cam-ring Z916 is mounted on a hollow hub Z920, secured to or forming part of the disk 1917, and the said disk and hub are loosely mounted on a bolt b21, secured to the cam-ring tithe said disk and 9o hub being frictionally held in proper or` adjusted position by the spring Z922, encircling the rod b21 outside of the disk bw. f

The disk 517 is provided on its periphery with a series of projections c, which are adapted, as herein shown,to strike two studs or'uprights c c2 on levers c3 c4, pivoted, as at c5 c, to the bed-plate a, the said levers being joined'together, as herein shown, by a pivoted rod, bar, or lever cs, extended up through the Ioo bed-plate and through slots @Tin the overlapping ends of the said levers, as clearly shown in Figs. 1 and 2. The rod or bar c@ is pivoted, as at a9, to an arm or projection c10 on the bracket a', the lower end of the said rod being adapted to be acted upon by one or more cams c12 on the pattern-chain a3. The camrng as has secured to it, as by screw c, a bracket C15, extended outward from t-he camring, and having secured to or forming part of it an upright sleeve c1, provided with a vertical slot c, into which is extended a pin c1S on a rod c1, extended through and movable in the said sleeve. The rod c19 has secured to or forming part of it at its lower end a shoe 020, upwardly bent at one end, as at 3, and at its upper end the said rod, as herein shown, has secured to it, as by screw C21, a cap C22, provided with a cross piece or bar o23, upon which rests one arm 4t of a lever 024, pivoted, as at c25, to an upright C26, secured to the dial-cap c2", the other arm 5 of the said lever being extended down and normally kept pressed against the circumference or edge of the dial-cap by a spring G40, secured to the lever C24 and to the bracket c, the said arm 5 acting as a catch or nipper to hold the re-enforcing thread while it is not being knitted, the arm 5 of the said lever releasing the re-entorcing thread when the rod c19 is raised, as will be described.

In the normal operation of the machine plain knitting is produced, and at such time the highest portion of the cam o16 acts on the rod lili and forces the spring-actuated lever U2 in toward the cam-ring, thereby carrying the thread-guide in toward the center of the machine within the needle-cylinder.

To re enforce the garment at certain points--as, for instance, at the knee ot' a stocking-I have provided the pattern-chain with a cam or lump C12, so placed as at the proper time to act upon the lower end of the lever ce, pivoted at C10. This cam or lump cl2 is so located that when the re-enforcing is to take place it will in the movement ot' the chain contact against one side of the lower end ot' the lever es, as represented in Fig. 1, thus throwing the upper end of the said lever inward, thereby moving the levers e3 c4 from their full into their dotted line positions, thus placing the studs or posts c c2 in the path of movement of the disk b, so that on the next revolution of the cam-ring as in the direction indicated by arrow 40, Figs. 1 and 2, one of the projections c (marked 10 in Fig. 1) strikes the post e and the disk 517 is vrotated in the direction indicated by arrow 4l, bringing the narrowest or smallest portion ot' the cam b1 into engagement with the arm or rod i215, thereby permitting the lever B12 to be moved outward by the spring CZ and carry the threadguide carrier b3 from the center of the machine outward a suflicient distance to place the thread-guide b outside of the cylindernecdles, thus drawing the thread across the said cylinder-needles and into position to be engaged by them. Immediately after the disk b has passed by the post c the shoe c2@ rides up over the said post, thereby raising the rod c1J and lifting the arm 4 of the lever c2, turning the said lever on its pivot and moving the arm 5 out away from the dial-cap, thus releasing the thread passing through the guide b and leaving itt'ree tobe engaged by the cylinder-needles and knitted to form the re-enforce. The machine will knit with both threads until in the revolution of the cam-rin g a second projection c (marked 12) on the disk b strikes the post c2 on the opposite side of the machine.

When the projection c (marked 12) strikes the post c2, the said disk is turned still farther in the direction of arrow 41 and the raised or highest portion of the cam b1 brought into engagement with the arm Z215 of the springactuated lever, thereby forcing the said lever in toward the cam-ring and moving the carrier b in toward the center of the machine to place its thread-guide b inside of the cylinder-needles. Immediately after the disk b17 has passed by the postc2 the shoe c1 rides over the said post and opens the thread-nipper--that is, the arm 5 of the lever 024 is moved away from the dial-cap-and as soon as the shoe has passed beyond the post c2 the lever cL4 is brought against the dial-cap and Iirmly nips the thread, and on the continued movement of the cam-ring a8 in the direction of arrow 40 the thread between the nipper and cylinder-needles is broken oit from the knitted goods, the said thread being still held between the nipper and the thread-guide. In this manner a re-enforcing course is knitted and the machine will continue to thus knit as long as the cam 012 remains in engagement with the lever o8. The cam c12 is made of suitable length to engage the lever o8 until the desired or required amount of re-enforce is knitted, and, as herein represented, the said camis made of a length suilicient to enable only a small re-enforce to be knitted, and if a long re-enforce is to be knitted the cam cl2 will be made longer than shown. The camring b1, as herein shown, is provided with three steps or cams; but in practice only two of said Steps are employed-viz., the highest and lowest. I claim- IIC) 1. In a circular-knitting machine, the combination, with the needle-cylinder, the cam-ring as, a stationary thread-guide, and a movable thread-guide and its carrier, of a disk'b17,piv oted to the cam-ring a8 and provided with one or more cams, an actuating device for the movable carrier operated by the said cams to effect the movement of the movable threadguide carrier, levers c'rs c4, provided with posts c c2 to rotate the disk 1)", a pattern-chain, and a lever e8, connected to the levers c3 c4 and acted upon by the pattern-chain to move the said levers, substantially as described.
