MACHINE FOR. WINDING THREAD.

i Specification of Letters Patent No. 31,858, dated February 5, 1861.

To all whom it 'may concern:

Be it known that I, EDGAR M. STEvENs, of

Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in. Machinery for Spooling Thread or Yarn; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1, is a top view; Fig. '2, aside elevation, and Fig. 3, an underside view of a machine containing my invention, which consists in a peculiar combination of mechanism, 'the object of which is not only to produce the reciprocating movements of a yarn guide relatively to a spool while in revolution, but the variation of the velocity of such movements in such manner as will adapt the machine to the correct spooling of thread or yarn of any diameter or size such as it may7 be desirable to wind on the spool carried by the machine.

The nature of the said invention consists in the combination and arrangement of an adjustable circular plate worm gear and its rotary screw with a cam wheel and cam ap? plied to put in action the thread carrier or guide, the whole being made to operate together and with the spool and the mechanism for putting such spool in rotation substantially as hereinafter explained.

In the drawings, A, denotes a spool or bobbin carried by an arbor, B, which is supported by a puppet head, C, elevated on a frame or table, D. Furthermore, from the said table, a spindle, a, extends upward and is for the purpose of carrying a bobbin, I), from which the thread, c to be wound upon the spool, A, is to be taken. This thread passes twice through an arm, E, and through a notch, made in its outer end, the said arm being extended from a vertical shaft, g, which projects both above and below the table, turns in a suitable bearing, t, and carries another arm, z'. A small stud or pin, extending from the arm, rests against the working surface of a cam, F, which is affixed to one side of a wheel Gr that runs on a pin Z, extended from a lever, m. The periphery of the wheel, G, works against the lower side of a circular plate or worm gear, II, which is supported by and so as to be capable of freely rotating on a stud, 0, extended froni a long lever, I. This lever, I, lies against the underside of the table, D,

and turns on a fulcrum, y), arranged at or near one end of such lever as shown in the v drawings.

The inferior side of the worin gear II, is

a flat surface. A long worm or screw K, engages with the toothed periphery of the said worm gear, and is arranged with reference thereto as shown in Fig. 3. This screw,

is borne up to the gear by a spring L, and is suitably supported in bearings so as to be capable of being put in revolution by means of an endless band, M, which works in the grooved periphery of a driving wheel, N, and around four pulleys, O, P, Q, R, one of which, (viz. P) is fixed `on the shaft, S, of the screw, K, while another (viZ..It,) is carried by the arbor, B. Thus, while the wheel N, is in rotation, the said arbor, B, and the screw, K, will be put in revolution.

The wheel, G, is borne up against the lower or inferior surface of the gear, I-I, by a spring, T, connected to the levers, m, and I.

By means of the lever, I, axis of the wheel H may be moved either nearer to or farther from the wheel, Gr, the two wheels being all the time in contact. As the worm gear receives its rotary motion from the screw K, and remains in engagement with such screw, and furthermore as the flat surface of the worm gear imparts rotary motion to the wheel, G, and its cam, F, it will be evident that the nearer the wheel, G, is to the axis of the wheel I-I, the slower must be the rate of revolution of the said cam.

The cam should be so formed as to impart to the thread carrier equal degrees of motion in equal times, and not only move the thread carrier from one head to the other of the spool, but so regulate its return or backward movement that it shall be at a regular rate, each of the two movements being such as will wind the thread or yarn on the spool in a regular helix having its coils in close contact with one another. The return movenient of the thread carrier is effected by a spring, U, attached to it and a post, V, projecting upward from the table, D.

From the above it will 'be seen that the ner the thread or yarn to be wound on the spool, the slower should be the motion imparted to the thread carrier; also, that by laying hold ofand moving the lever, I, we can vary the rate of motion of the thread guide as circumstances may require.

The lever I, may serve as an index to a divided are suitably placed on the table, such arc indicating,` by its divisions and figures, the Various positions of the lever or 5 the adaptation of the machine to the spooling 'of Various sizes or numbers of yarn or thread.

I claim- The combination and arrangement of the adjust-able plate 'Worin gear, H, and its ro- 10 tary screw, K, or their equivalent or equivalents with the cam Wheel, G, and the cam, F, applied to operate the thread carrier substantially as specilied.
