lNvENTuR. MM i JOHN v. ounmrr, or FALL nrvnn, MASSACHUSETTS, riserson or QivE- T PATTEN BROS, INC., 0]? FALL RIVER, MASSACHUSETTS WINDING-IEACHINE.

Application filed February 1t), 1920. Serial No. 357,555.

. To all whom it may concern:

Be it known that 1, JOHN V, CUNNIFF, a citizen of the United States,-res1ding at Fall River, in the county of: Bristol and State oi Massachusetts, have invented new and.use-' is of simple and economical construction and positive and certain in its operation.

Further and other objects of the invention will be manifested and set forth in the following description.

In the drawings:

Figure l is a bottom plan view of the invention, and

Fig. 2 is a side elevation, parts being shown in section.

In proceeding in accordance with the present invention, any number oi individual structures embodying the invention may be secured to the spooling bar 1 of the machine. Brackets A are employed which are attached to the bar 1 and which carry spindles 2 upon which latter the bobbin 3 is supported. The bracket A. has a main arm a rigidly connected thereto, the outer or free end of the nate therewith. The pivoted arm 8 has an adjustable weight 10 between its ends, and at its inner end has a guide eye 11. The main arm 4: is provided with a top stop 13 and an adjustable stop 12, one for limiting the upward and the other the downward movement of the pivoted arm 8.

In operation the thread passes from the bobbin 3, under the adjacent prong 7, over the prong 9 between the prongs 7 thence under the other prong 7 and up over the other prong 9, thence over the curved friction plate 5 through the guide eye ll, over the gulde rod 14 and thence to the spool which may be operated in any manner.

It will be noted from the foregoing that as the diameter of the thread wound on the spool increases it will be necessary to feed this thread more freely, and accordingly the pull on the thread will lift the guide eye 11 of the pivoted arm 8 just suflicient to permit tree movement of the thread for winding purposes, by slackening the tension on the thread as it comes from the bobbin 3. This 1s obviously; due to the iact'that the prongs 7 and 9 are brought nearer to the same plane, so that the thread has a straighter draw instead of a tortuous one, the latter depicted in Fig. 2.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent is 1. In a winding machine, a bracket for attachment to the spooling bar having a main arm formed with a curved friction plate, a bobbin spindle carried by the bracket, an arm pivoted to. the main arm and having a thread eye at one end, a weight adjustable on the pivoted arm, stops for the pivoted arm borne by the main arm, a plate on the main arm having spaced prongs and prongs carried by the pivoted arm and arrzinged to alternate. with the prongs of the p ate.

Specificationof Letters Patent, Patented Apr. 19, 1921 i 2. In a tension device, a bracket provided v with a friction plate, a series of spaced prongs on said bracket arranged to the rear of the friction plate and approximately alined with the lower end of said plate, an arm pivoted to the bracket, spaced prongs carried by one end of said arm and arranged to alternate with the bracket prongs, a thread eye on the opposite end of the arm, and a horizontal bobbin support carried by the bracket and substantially alined with the prongs.

3. In a tension device, a bracket provided with a friction plate, a series of spaced prongs on said bracket arranged to the rear of the friction plate. and approximately alined with the lower end of said plate, an arm pivoted to the bracket, spaced prongs carried by one end of said arm and arranged to alternate with the bracket prongs, and a thread eye on the arm above the plate, said plate being arranged to guide the thread from the prongs upwardly to the thread eye.

means on the bracket, an arm pivoted to the V bracket and having thread tensioning means cooperating with the first named means, and

, a thread eye on the arm, the friction member belng formed and arranged to engage the thread after the same leaves the tensioning means and to then guide the thread directly to the eye.

5. In a' tension device, a bracket having means forattachment to the spooling bar of awinding; machine, a bobbin support carried by the bracket, thread tensioning means on the bracket, a pivoted arm on the bracket havingthread tensioning means cooperating with the first named thread tensioning means, and an eye on the pivoted arm arranged to receive the thread directly from said friction member so as to move the arm upwardly at its rear end by a direct pull tion plate on the opposite end of the bracket, 7

arm pivoted on the bracket and having athread eye on one end for disposition adja- "cent to the spooling bar, and cooperating thread tensioning means between the opposite'end of the lever and the bracket and arranged to the rear of and adjacent the triotion plate.

7. In a tension device, a bracket, a friction plate on the bracket, a pivoted arm on the bracket having a thread eye 011 its rear end, and cooperating thread tensioning means between the front end of the arm and the bracket, said eye being located above the plate and the latter being formed to guide the thread vertically and upwardly after same leaves the said tensioning means.

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

JOHN V. CUNNIFF.
