KNITTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,752, dated February 14, 1882. Application filed November 9, 1881. (No model.)

To all whom it may concern Be it known that I, GEORGE E. NYE, of Bris-' Circular Glass; and I do hereby declare the.

same to be described in the following specification and'represented inthe accompanying drawings of which- Figure 1 is a top View, Fig. 2 a front elevation, Fig. 3 a side View, and Fig. 4 .a vertical section, of a machine embodying my invention. Fig. 5 is an under side view of the dial-needles operative cams and their supporter. Fig. 6 is 1 hereinafter described.

The nature of my invention is defined in or by the claims hereinafter set forth, its object being the production of certain changes, to be hereinafter described, in knitting the ribbed fabric, such changes being produced by the drawing-in cams and their operative mechanism, to be described.

In carrying out my invention I have combined with the push-out cams of the dial-needles of a machine for the production of circular rib-knitting two movable drawing-in cams and certain mechanism, as hereinafter explained, for operating these latter cams.

In the drawings, the vertical needles are 0 shown at a and the horizontal ones at b. The

needles of the former set are arranged in the ordinary manner in grooves in the outer periphery of a rotary cylindrical tube, A, while the horizontal needles are disposed in radial 3 5 grooves within a rotary circular plate, B, usually termed the dial. The supporter of the cam of the dial-needles is shown at O as provided with the stationary cam-plate D, formed or provided with the push-out cams c c. The 49 said plate D is between two movable cams, E F, formed and arranged, as shown in Fig. 5,

on the lower part of the supporter 0. Each cam is pivoted to the supporter at d, and also to one of two slides, G H, arranged within the supporter and relatively to the cain-plate D, in manner as represented in Fig. 5, and more especially as shown in Fig. 6, which is a vertical section of the supporter and the two slides.

Opposite to each push-out cam is a yarn- 5o guide, 6, through a hole in which the yarn is led to the needles. The two slides G H, by means of linksff, are connected to the upper arms of two angular levers, I K, fulerumed to the upper part of a stationary post, L. From the lower arms of these levers two studs, g h, project, and have between and against them a cam, M, formed as shown, and fixed on ashort shaft, 2', upon which is fastened a wormgear, k, that engages with a worm, l. This .worm revolves freely 0n a short horizontal 6o shaft, m, provided with a sliding clutch, n, to engage the gear with or disengage it from the shaft, as occasion may require. ()n the inner end of the said shaft m is a bevel-gear, n, that engages with the gear 0 of the rotary tube A, such tube being revolved by a gear, 19, which is fixed on the driving-shaft g and engages with the gear 0.

To the levers I K springs 'r r are adapted to keep the studs of the levers up to the periph- 7o e'ry of the cam M, such springs being projected from the circular head N for supporting the knitting-machine. Furthermore, from the upper arm of one of the levers I K a stud, 8, projeets. A latch, O, pivoted to the head N and 7 5 notched to receive the stud 8, serves, when caught in the stud, to hold the lever stationary, in which case the draw-cam of the lever will be maintained in its closest position to the cam-plate D, the upper draw-cam being mov- 8o able toward and from such plate while the cam M may be in revolution.

The vertical needles are to be supposed to be operated by suitable cams while the tube A may be in revolution, the number of such cams corresponding to the number of threadguides. If new we suppose the two yarns of the two thread-guides to be of difierent colorsthat is, one to be red and the other blue, for instance-the ribbed fabric produced may have 0 what may be termed a striped, checked, or block-work appearance, either being produced, as may be desired. If we wish to knit the striped work, unclutch the worm from its by step one of the levers from working, and we clutch the worm to its shaft. The machine will 10 [[ttl V shaft, in which case the camMwill not revolve 5 Lb then perform the block-knittin g, which consists of transverse and parallel ranges of stitches, of which each range is of one color and the next oneof the other of the two colors. In the striped work the ribs are of one color and the intervening spaces of the other color. The check-knitting has the appearance of the squares ofa checker-board, each figure or portion of color being either square or rectangular, as may be required. To produce the check-knittin g, both levers are to be acted on by the cam and the worm is to be clutched to its shaft. These changes can be effected while the machine may he in operation, there being no necessity for stopping it in order to effect either of them.

What I claim in the circular rib-knitting machine as my invention is as follows:

1. The combination of the stationary camplate D and the two movable cams E F and their operative mechanism, consisting of the slides G H, links ff, levers l K, post L, cam M, shaft 2', worm'gear k, worm l, shaft m, and clutch n, all being applied substantially as specified.

2. The combination, with the head N, latch O, and adjustableoam, of the lever I, provided with studs, and mechanism for operating said lever, substantially as specified.

GEORGE E. NYE.
