SPECIFICATION forming part of Letters Eatent No. 22,490, dated January 29,1884.

Application filed April 16, 1883. (No model.)

To aZZ 1072,0112 it may concern;

Be it known that I, WARREN D. HUsE, of

Laconia, count-y of Belknap, State of New.

Hampshire, have invented an Improvement in KnittingMachines, of which the following description, in connection with the accompanying drawings, is a specificatiom'like letters on the drawings representing like parts.

This invention is an improvement on United States Patent N 0. 239,168, granted to me March 22, 1881, and has for its'object to increase the capacity of the said machine, both as to the amount of work and, the variety of color in the fabric, and consequently of patterns, which may be produced thereon. In the machine described in the patent referred to two yarns of different colors were employed, and when it was desired to change from one to the other ative position, and its thread was automati-.

cally broken off. In the patented machine referred to the pattern-chain could not be moved for morethan one step at one revolution of the cam-cylinder which. actuates the needles, and the cam-cylinder had but one set of knit; ting-cams, so that but one change of color could be made at any one rotation of the camcylinder. of the machine as to colors of yarn introduced and varieties of pattern which could be produced. To increase theefficiency of the said patented machine, I have provided the camcylinder, and also the usual cam-plate for the dial-needles, with two sets of knitting-cams; and I have also provided the machine with two sets of yarn-guides, each composed of at least twoyarn-guides; and-I have also provided mechanism for operating both or either. of these yarn-guides during each rotation of the cam-cylinder; and I have also arranged. the gearing by which the pattern-chain is operated so that the said'pattern-chain is or may be turned twice during each revolution of the cam-cylinder, thus enabling eitherone of four yarns in the four yarn-guides to be thrown into or out from action during any one course of knitting;

Such construction limited thescope chine when the yarn-guides are as in Fig. 6;

Fig. 10, a similar view, with the yarn-guides as in Fig.8; Fig. 11, adeveloped interiorview of the cam-cylinder; and Fig. 12,asimilar view of the dial-plate for moving the dial-needles, the said two figures last referred to being on a smaller scale.

The dial-plate A, dial-needles a, needle-cyl- 7o inder B, cylinder-needles b, cam-cylinder O, yarn-guides D E, swinging arms G'H, pivot c, levers I J, pit ot d, studs or pins e,yarnchanging pattern K, having camsf and teeth i, pivot g, springs h, rod L, machine-frame M, 7 5' lever N, pivot Stud k, disk 0, ratchet-wheel Q, pattern-chain P, links Z, projections m a,- screw p, bevel-wheel R, eccentric V, counterweighted lever W, pawl q, spring 1', catch-1e ver X, pivot s, cam 10, and yoke z are the same in construction and operation as in mypatent referred to, except as hereinafter pointed out, and the said devices are designated by like letters.

The cam-cylinder, provided with gear-teeth a at its lower end, (see Fig. 2,) is engaged by a bevel-gear, B on the shaft B provided with loose and fast pulleys B B the said shaft being extended through a part, M of the frame',l\I.- In this my present invention the 0 cam-cylinder 0 (shown developed in Fig. 11) has two sets ofknitting-cams, (1?, of usual construction, at nearly opposite points, to operate the needles b twice during each revolution of the cam-cylinder, and at its outer side the 5 said cylinder carries two extra pairs of yarnguides, D E, like those marked D E, and cooperating with the same are arms G H, actu ating-levers I J, pattern K i f, and a lever, X a, springs r h, the same as those at the opposite side of the cam-cylinder O, and marked with like letters without, the prime. The

cam-plate C (see Fig. 12) has also two sets of knitting-cams, Zr, each to operate the needles a twice during each revolution of the can plate, thus enabling two courses to be knitted at each revolution of the cam-cylinder and cam-plate, and also enable either or both of the yarn-guides of each set to deliver the yarn carried by it to the needles for the whole or part of each knitted course. The teeth a of the cam-cylinder engage the teeth of the bevelgear R common to my said patent; but the latter gear has a gear, I)", connected with it, which engages the gear I), with which is attached the eccentric Y. These gears b b are, however, of such size with relation to the gear R and the ratchet Q that the latter is moved for the space of two of its teeth during each revolution of the cam-cylinder, so that the said ratchet'wheel and pattern-chain P, the links Z of which are supposed to be of a length suiticient to control the color of the yarn used for four successive courses, is movedsufliciently far at each stroke of the pawl q to carry a link, 7, completely under and past the pin it of the lever N. The links have projections 21, of various widths and located at different points thereon, in order to determine which pair or set of thread-guides is to be operated during acertain revolution of the canrcylinder, or whether both of the said sets are to be operated at each revolution of the said cam-cylinder in successive or alternate courses, a narrow projection, n, holding the rod L up only while the ratehet-wl1eel Q is moved one step, whereas a broader projection, as at of, will hold the said rod L up while the said ratchetwheel is moved two steps or more, according to how much of the length of each link is occupied by a projection to hold up the lever N. In the patent referred to the ratchet-wheel is moved but for one step during each rotation of the cam cylinder, and but one color could enabled to produce four courses of knitting during any two revolutions of the cam-cylinder, and the said four courses may all be produced with yarns of different colors, and either color may appear in either course, that being determined by the location of the projection on the links Z of the pattern-chain.

The bobbins for yarn, two only of which are shown, are supported on a plate e", and usual tension devices (not shown) for the said yarns will be carried by the rod 0.

The bed for the dial-needles is marked f*.

I claim The eanrcylinder having two sets of knitting-cams, the cylinder-needles, needle-bed, the bed or plate for the dial-needles, the camplate, the dial-needles, and two sets of knitting-cams on the cant-plate, and two sets of yarn-guides composed each of two separate yarn-guides, combined with two yarn-changing patterns, a pattern-chain, and'means actuated thereby to permit the two yarn-changing patterns to be moved at each revolution of the cam-cylinder, and with means to rotate the said cam-cylinder and to move the pattern chain two steps at each revolution of the camcylinder, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing wit nesses.
