STRAIGHT-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,343, dated September 6, 1887.

(No model.)

To aZZ whom it iii/any concern:

Be it known that I, ROBERT KLINe-ER, a resident of Jersey City, in the county ofHudson and State of New Jersey, have invented an Improved Knitting-Machine, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure 1 is a side elevation of my improved knitting-machine. Fig. 2 is a detail face view of a cam for reciprocating the needleloed. Fig. 3 is a detail section through the movable threadguide, showing the tension apparatus with which it is provided. Fig. 4: is an end View, partly in section, of the machine. Fig. 5 is a detail cross-section on the line 0 c, Fig. 4. Fig. 6 is a top view of part of the machine. Fig. 7 is a detail back view, on an enlarged scale, of one of the thread guides E and switches G.

This invention relates to improvements on the class of knitting-machines which is known as the Lamb knitting-machine, its principal object being to so arrange the machine that two or more different fabrics, varying in width or of the same width, may be made on the same machine at the same time.

The invention consists in the novel arrangements and combinations of parts hereinafter more fully described.

In the drawings, the letter A represents the reciprocating carriage of the Lamb knittingmachine, the same being placed against the doubly-inclined needle-bed B, that is rested on the stationary frame 0. The slide A is reciprocated by being connected with the driving-shaft D by aconnecting-rod, a, and crank b. The stationary frame 0 supports on posts (Z d stationary rails e, on which'the several thread-guides E E are adapted to slide. In the drawings are shown three such threadguides E, each adapted to lay a thread into a certain series of needles, and each intended to reciprocate through a certain portion of the machine, into which portion none of the other thread-guides will enter. For the purpose of moving and properly arresting these threadguides E E, I use a spring, F, (see Fig. 4,) which projects from the reciprocating carriage A behind the rails e c. This spring F has a projecting lip, j, which in Fig. 6 is shown to bear against a rcarwardly-projecting nose, g,

of one of the thread-guides E. Each of the several thread-guides is provided at each side with such a projecting nose, which lies in the path of the lip f on the spring F. On the rails e e are also placed switch-blocks G G, which are clearly shown in the top view, Fig. 6. They are adjustable on the rails and can be secured thereto by set-screws m, or other suit able means, so that the distance between them may be varied at pleasure, and have inclined ends it 71., as shown.

Whenever the spring F bears against one of the noses g of a thread-guide, it moves that thread-guide along with it until the lipf on the spring strikes one of the switch-blocks G, which is held fast to the rails e. The motion of the thread-guide is now arrested, but the spring F, being rigidly fastened to the reciprocating carriage A, moves along and 1s, on the first inclined edge h of the switchblock, pushed back to be disengaged from the nose of the thread-guide it last moved. After this the spring F moves along the back of the switch G until it reaches the other inclined edge h, when it springs out again to come in the path of the nose 9 of the next thread-guide, and so on, until all the thread-guides have been moved in one direction.

The switch-blocks at the ends only have single inclined edges h, as indicated at one end of Fig. 6. The switch-blocks G are on a different plane from the noses g of the sliding threadguides, as appears more clearly from Fig. 7 of the drawings, so that whenever the spring F has brought a thread-guide to the end of its proper stroke the spring will then be taken off the contact with the nose 9 by the switchblock, leaving the thread-guide at rest.

In order to insure the exact termination of each motion of each thread-guide I provide the latter with a tension attachment, which is more clearly shown in Fig. 3, and which consists of a screw, i, bearing upon a spring, j, which in turn bears upon a washer, is, that rests on one of the rails e. The spring is contained within aproper recess of the threadguide, as shown, and produces the requisite amount of friction which will cause the thread guide to remain at rest the moment the spring F ceases to actuate it, leaving the threadguide, nevertheless, free to be readily moved by contact with the spring.

n in the outer groove, 0, of the cam I, which is.

along the rails c.

The spring F is, by preference, provided with a slot, through which passes a pin, Z, that projects from a rigid post, m, which stands on the carriage A. This leaves the spring F rigid in the direction of the motion of the carriage and elastic at right angles to that motion.

From what I have already described of the knitting-machine it will be perceived that, by the means of the spring F, switch-blocks G, and sliding threadguides E, I am enabled to move the series of thread-guides, one after another, Each of the thread-guides may be moved over a path which differs in extent from the length of path of each of the other thread-guides, or all may be moved equally far by the spring F; hence, by properly adjusting the switch-blocks G in position I am enabled to knit on one machine at one time several different fabrics, one of coarse thread and one of fine thread, or all of the same kind of thread, and again by removing all the switch-blocks except those at the very ends I can utilize the whole length of the machine for making but a single fabric.

In order to adapt the machine for the production of the zigzag or racked stitch it is necessary to move the needle-bed B back and forth longitudinally a short distance. To effect this operation I connect the needle-bed B with a rod, H, which carries a crescentshaped block, n, within a grooved cam, I, that is mounted upon the shaft D. The cam I has two concentric grooves, o and p, separated by an intervening arched rib, q, the outer groove, 0, being surrounded by a rim, 1", having an inward projection, s, opposite the center of the opening in the rib q. The inner circumference of the inner groove, p, is formed by a cam-shaped attachment, t, on the shaft D.

Fig. 2 shows the crescent-shaped projection the position in which the rod H will hold the needle-bed B to the left, as in'Fig. 1. As the cam I revolves, the crescent'shaped block a will, by the projection s, be crowded into the inner groove, 19, whereby the needle-bed B will be drawn to the right until it touches the edge or face a. (Shown in Fig. 1.) A subsequent revolution of the cam Iwill bring the crescentshaped block a back into the outer groove, 0, and thus push the needle-bed to the left again, and so on. The block a, of course, is swiveled by its pin to the rod H, so that'it will readily turn from one groove of the cam I into the other.

outer end normally against one arm of an el- 6 bow, O. The other arm of this elbow supports a slide, I, (see Figs. 4 and 5,) which lies in the path of a double cam, Q, that is mounted upon the driving-shaft D. Whenever the cam Q strikes the end of the slide Pit depresses that slide, tilts the elbow O, and pushes the rod N and pawl w so as to turn the ratchet-wheel o and its roller a certain desired distance, pref- Y erably the distance of onetooth of the ratchet- Wheel.

The cam Q is double, for the purpose of moving the pawl to twice during each revolution of the shaft D, which is once for every longitudinal motion of the carriage A.

I claim- 1. In a knitting-machine, the reciprocating carriage A, having slotted spring F, with lip f thereon, and rigid post m, carrying pin Z, in combination with the stationary rail or rails e, thread-guide E, having noses g g, longitudinally-adj ustable and separate switch-blocks G, and screws 00, all arranged substantially as and for the purpose herein shown and described.

2. The reciprocating thread-guide E, combined with the rail or rails e, on which it is adapted to move, and with the tensionscrew z and tension-spring j, substantially as and for the purpose specified.

3. The combination of the cam I, having rim 1, with projection s, arched rib q, inner cam-piece, t, and communicating grooves 0 and p, with the swiveled block a on the rod H, and with the needle-bed B of a knittingmachine, for the purpose of reciprocating said needle-bed, as specified.

4. The combination of the shaft D and double cam Q, with theslide P, elbow 0, springactuated rod N, pawl 20, ratchet-wheel v, and

rollers L M, for application to the fabric ten sion device of a knitting-machine, substantially as herein shown and described.
