To all whom'z'fmdy concern Beit anaemia-arr; Davin w- Iiiiii-ire,

ac-itizen of the United States; residing Oregon City, in the county of Clack and State of O'regon', have inventedee'rtain new and useful Improveme ts Tension Attachments" for Windin Mae fines; of which the following is a specification.

The present invention relates to an im; roved tension device for winding machines; and has for an object to provide inrproved means for varying the. tension tic-'- cording to. the size of yarn'which is being wound:

Another object of the invention is to provide a variable tension device of this character which may be easily and quickly applied to the usual type of winding machines without changing or substituting any of the parts thereof.

Briefly stated, the invention embodies a weight, arm which may be hooked upon the usual winding machine in lieu of the ordinary weight and which is held in position upon the machine without the use of brackets, pivots, or the like, and which is per mitted to swing or rock upon its fulcrum for exerting the desired pressure on the yarn.

The invention further aims to provide a quick attachment for winding machines wherein a single weight is used and wherein the weight may be quickly adjusted to exert the desired pressure, and wherein the position of the weight may be determined ac cording to the size of yarn or the tension desired.

The above and various other objects of the invention will in partbe described in and in part understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein Fig. 1 is a fragmentary end elevation of a winding machine having the tension device of this invention applied thereto, and

Fig. 2 is a detail perspective view of the improved tension device.

Referring to the drawing, 10 designates a winding machine of ordinary construction having a spindle 11 on which yarn 12 may be wound, the yarn being taken from a bobbin or spool 13 or other suitable source of supply. The machine carries a tension arm 14 having friction or tension discs 15 between which the yarn 12 is drawn during Serial no. 658,974.

otejc'l" upon a horizontal od 17" a the tension ans 14'. is usually. cons of which is loop weights re selected according to the size of the yarn and the tension desired, and hung upon the hook 20.

The-present invention rovides a weight lever 21 of suitable lengtli provided at one end with a laterally extending fork22 the arms of which extend upwardly and are spaced apart a distance suflicient to freely receive therebetween the loweredge of the tension arm 14. The fork 22 is merely placed up against the arm 14 so that the lever 21 may rock upon the fork as a fulcrum. The arms of the forkhold the lever 21 from lateral displacement-(Y Spaced a short distance from the fork 22is an eye 23 formed in the lever 21 for receiving .the hook 20 thereto so that the lever is suspended on the hook instead of the usual weight. The outer end of the lever 21 is provided with a row of suitably spaced .apart openings 24 adapted to receive a hook -25 of a weight 26. The hook 25 may be engaged in any one of the openings 24, and;v the openings represent different tensions for the weight upon the hook 20. V

The lever 21 may be stamped; and bent from sheet metal and the weight may be formed of any suitable materiakhaving the necessary specific gravity, such as iron so that the weight may be of .aiconvenient size for handling and will not" be bulky or in the way. The weight preferably is of two ounce size because its eflective pressure may be varied according to its position upon;

the lever 21.

The tension device may thus be easily and economically manufactured and may be quickly applied by merely placing the form 22 against the lower edge of the tension arm 14 and fitting the arm 23 over the hook-20. The weight 26 is then suspended upon the lever 21 so as to exert a downward pull on the hook 520 variable according to the position ofthe weight 26.

Various changes and modifications may be made in the details of construction and design of the above specifically described em bodiment of the invention, the same being restricted only by the scope of the following claims. a

What isclaimed is:

1. A tensiondevice for winding machines having the usual tension arm and weight hook, comprising a lever provided upon one end with an upwardly extending fork for seating against the tension arm and having an eye spaced from the fork to receive said hook therein, said lever having a plurality of openings spaced longitudinally of the lever between the eye and the free end of the lever, and a weight removably positioned in said openings for exerting a variable pressure upon the weight hook.

' 2. A-tensiondevice of the character described comprising a lever having a row of openings spaced longitudinally of the lever and having a pivot eye inwardly of said openings, said lever having a lateral disposed portion upon its inner end having upwardly extending fork arms and adapted to serve as a fulcrum upon which the lever may swing, and a weight arranged for selec tive engagement in the first mentioned open ings of the lever.

3. A tension device for winding machines comprising a flat bar having a fork bent laterally from its inner end and having its arms extending upwardly for engagement about the tension arm of a winding machine, said bar having an eye spaced from the fork to receive the weight hook of a winding machine and further having a plurality of openings spaced longitudinally of the bar between the first mentioned opening and its outer end, a weight, and a hook on the weight for selective engagement in the last mentioned openings. 7
