Application filed April 27, 1911. Serial No. 688,855.

To all whom it may concern:

Be it known that we, Xnnus Mrqupna, a subject of the King of Greece, residing at West Hoboken, county of Hudson, and State of New Jersey, and Fnnonmo Rommn,

a citizen of the United States, residing at.

New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tension Devices, of which the following is a specification.

Our invention relates to a tension device to be used in the winding of thread, yarn or the like, for instance in quilling or similar winding machines, and it consists incertain improvements in such devices whereby a high degree of uniformity of tension ma be se cured and a tension device produce which is susceptible of use in connection with the windin of thread or yarn widely differing in tens] e stren h and other characteristics and substantial y regardless of the speed at which the winding proceeds.

Referring to the accompanying drawing, wherein our invention is fully illustrate Figure 1 is a perspective view of the improved device; Fig. 2 is a to plan view and Fi 3 a front elevation t ereof; and, Fig. 4 illustrates a detail.

a is a suitable bracket or supporting member having a stem 6 serving as a convenient means whereby to attach it to the frame of the machine in which the device is used. This bracket has its top'face c and front face at arranged in planes atright angles to each other and, said faces having recesses e and f respectively, communicating with each other, it is provided with opposed" resulting from the cutting away shoulders of the material of the bracket to produce the said recesses (Figs. 2 and 3).

Projecting from the recessed portion of the front face of the bracket are two studs in (preferably of wood) having heads a and arranged parallel with each other. On

these studs are journaled c lindrical rollers ing, in the adaptation shown, of a piece of wire having one end at bent oif to form a head or stop and. an appreciable part thereof includin its other end bent oil at right angles to orm a stem or pivot-portion n. This wire, on the body part 0 of which the roller is is journaled, has its stem n received by a vertical hole p extending down throu h the bracket a centrally from its recess e, t e hole being appreciably larger in diameter than the stem, so that the stem stands perfectly free therein. The thread A, in the present adaptation, extends under one roller j, over the roller 1:, and then under the other roller 7', so that a bend B is maintained therein. Bends C of more or less degree, as the circumstances ma require, maybe maintained in the threa where it extends around the roller j in any suitable manner in the present instance guides q being used for this purpose. These guides are shown situated relatively above the three rollers and one at one side and the other at the other side thereof, each guide being L- shaped in side elevation and havin its stem 1' extending into a suitable hole a ormed in the top of the bracket and held for vertical and rot-ative adjustment by a set screw 15 or any other convenient expedient. It will be understood that by rota-tably adjusting either or both of the guides, or by adJusting either or both of them vertically, various degrees of tension will result, princi ally because such adjustments alter the c aracter of the bends in the thread at C.

In operation, the thread is kept within the contro of the rollers at all times by the guides g. The rollers j are mounted on fixed bearin h h, whereas the roller is is free not on y to rotatebut to vibrate, so that in action it may assume a variety of positions relativel to rollers j 7',- its normal position is t at shown in Fig. 3, in which position regarding either of the rollers j j the other and member I tend always to retain it. Any vtendencyfor roller is to move laterally in its vibrations so far as to fail .roperly to ooact with rollers 7' j is usual y prevented by the thread itself; but such movement is positively prevented in the device as herein particularly shown and described by the shoulders g g the dotted outline in Fig. 2 indicating the limit of lateral movement thus afiorded roller is. Endwise movement of roller is is limited by stop m and the bracket a. It will be noted that the ends of the rollers j and k which adjoin the support a are recelved in the recess This insures the thread against working over these ends of the rollers and perhaps snarlin about the 'studs h and member 1'. In a justing the thread or yarn to the tension device the operator, holding the thread with both hands, passes the intervenin part of the thread over the, projecting ee or outer end-portion of the roller k (Fig. 2), then between and under the rollers j y to form the bends C, and then an ges the thread with the guides g.

n ractice it has been found that our tension evice is well adapted, because of its capability of automatically adjusting itself to varying conditions, such as wide dlfl'erences in speed of winding and various tensile strengths and other characteristics of the material to be wound, for use universally in the control of thread or yarn in the winding and similar operations, and that, while it serves at all times to preserve the tension uniform and regular in character, it is also calculated not to produce breakage of the thread.

We do not wish to be limited to the employment of three thread-engaged memers, nor to the members used being each cylindrical, nor to their bein each rotary, as these are not indispensabe features of the invention, what we claim bein 1. In combination, means for malntaining reverse bends in the thread including two normally contacting tension members arranged on substantially parallel axes crossing the thread line, one of said members hein movable out of parallelism with the ot er but bein normally forced into parallelism therewith by the thread, and one of said members being rotary, and means for supportin said members 1n cooperative relation witi each other, substantially as described.

2. In combination, means for maintaining reverse bends in the thread including two normally contacting tension members arranged on substantially parallel axes crossing the thread line, one of said members hein movable out of arallelisln" with the ot er but being normally forced into rallelism therewith by the thread, and fining also movable to and from the other member, and one of said members being rotary, and means for supporting said members m cooperative relation with each other, substantially as described.

3. In combination, means for maintaining reverse bends in the thread including three tension members arranged on substantially parallel axes crossing the thread line and each member normally contacting with v the other two members, one of said members being movable out of arallelism with the other two members ut being normally forced into parallelism therewith by the thread, and means for supporting said members in e06 erating relation with each other, substantial y as described.

In combination, means for maintaining reverse bends in the thread including three tension members arranged on substantially parallel axes crossing the thread line, one of said members resting upon the other two members and being movable out of parallelism but bein normally forced into parallelism therewit by the thread, and Ireans for supporting said members in cooperative relation with each other, substantially as described.

5. In combination, with a support, a tension member carried by the support, a vibratory thread-controlled roll'er arranged with its axis of rotation horizontal and normall held bearing down on the tension mem r by the thread, the thread being adapted to extend between said tension member and the roller and around the latter, and a controlling part for said roller aflording an axis therefor and movable in the sup ort vertically and also around a substantially vertical axis, substantially as described.

6. In combination, with a su port, a pair of tension members carried by t e support,a vibratory thread-controlled roller arranged with its axis of rotation horizontal and normall held bearin down on said tension mezrers by the thread, the thread being adapted to extend first between one of the tension members and the roller, then around the latter and then between the other tension member and the roller, and a controlling art for said roller 'aifording an axis thereor and movable in the su port vertically and also around a substantially vertical axis, substantially as described.

In testimony whereof we afiix our signatures in presence of two witnesses.
