CREEL EQUIPPED WITH AUTOMATIC TENSION DEVICE.

Application filed April 8,

This invention relates to an automatic tension creel which may be applied to any iachine for dressing the warp for the loom, and is particularly adapted for use at the spinning' frame where the spun yarn is tensioned before it is drawn into the loom. The yarn, which may be of any kind or any number, spun onto spools at the spinning` frame and these spools are inserted singly into my automatic tension creel and an uniform tension maintained on the yarn, regardless of the constant decrease in surface diameter of the spool, as the yarn is drawn off the spool. My automatic tension creel also permits the degree of tensioning effect to be varied according to the particular kind or number of yarn being run.

In accordance with my invention, I provide the creel with means for detachably holding a spool or supply roll, and I pivot adjacent the supply roll of the creel a ten sioning device which is counterweighted so as to constantly bear against and. maintain a uniform tension on the yarn drawing from said roll, regardless of the constantly decreasing diameter of the roll. 'Ihe tensioni ing effect may be varied by changing the counteriveights which act on the tensioning device to urge it towards the roll, thus permitting the degree of tension to be varied according to the character of the yarn being run.

The construction and operation of my tensioning device is described and illustrated in the accompanying specification and drawings, and the particular features of novelty are pointed out in the appended claims. In the drawings: l

Fig. l is a rear elevation of an automatic tensioning device in accordance with my invention.

Fig. 2 is an end viewthereof.

Fig. 3 is a front elevation thereof, and

Fig. l is a vertical section on the line 4 4 of Fig. 3. l

I have indicated at 1 a framework and at 2 a supply roll or spool which is removably journaled in suitable bearings 3 projecting from the uprights of the frame l at one side thereof, and from which roll the yarn or other strand is adapted to be drawn in the direction of the arrows, Figs. 2 and 4L, into the loom.

Set transversely through the end uprights of the frame above the supply roll 2 is a rock shaft 4 on which is mounted a yoke- 1926. Serial No. 100,522.

shaped tensioning device 5. One arm or the yoke 5 bears against the yarn on the roll 2, and .if desired said arm may carry a removable .tension plate 6, here shown as a glass plate engaged between marginal guides 7 formed on said arm. The opposite arm 5l, of the yoke is counterweighted, as indicated at 8, so as to constantly urge the tensioning plate G against the supply ,roll at all surface diameters of said roll. The counterweight 8 is pivoted to bear against the arm 5l and preferably is removable, so that it may be replaced by other counterweights of different weight, thereby pern'iitting the ten sioning effect on the supply roll to be varied according to the character of the yarn being run. To this end the counterweight 8 is suspended by arms 9 which are removably pivoted at l() in slotted bearings ll carried by the end uprights of the frame l.

In use, the yarn is `drawn from the supply roll in the direction of the arrow, Figs. 2 and 4l., and in its withdrawal is tensioned by the tension plate 6 which is constantly urged against the roll by the counterweight. As the diameter of the supply roll decreases the yoke 5 swings farther and farther to the left, Fig. 4;, so as always to bear against the roll and thus exert a tension upon the yarn as it is drawn therefrom.

Various modifications in the construction and operation of my device may obviously be resorted to if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

l. In combination, a rotatably mounted roll, a tensioning device pivoted at one side of the axis of rotation of the roll for arcual movement relative thereto and presenting a tensioning surface adapted as the surface diametel` of the roll changes to contact the roll along lines of bearing disposed in successive planes lying between the surface of the roll and the pivot of the tensioning device, and means associated with said tensioning device and acting constantly to urge said tensioning device against said roll whereby to exert a.

uniform tension thereon at all surface ldiameters of the roll.

2. In combination, a roll, a yoke-shaped tensioning device pivoted adjacent said roll, and a counterweight acting constantly to press one of the arms of said tensioning device against said roll at all surface diameters thereof.

3. In combination, a roll, a yoke-shaped tensioning device pivoted adjacent said roll in position to present one of its arins towards said roll, and a counterweight acting upon the opposite arin of the yoke. constantly to press said tensioning device against said roll at all surface diameters thereof.

a. In combination, a frame, a roll journaled therein, a yoke-shaped tensioning,` de vice pivoted to said frame above said roll and presenting a tensioning surface to said roll and a counternf'eighted surface opposite said tensioning` surface and normally tending,l to urge said tensioning surface against said roll at all surface diameters thereof.

5. In combination, a frame, a roll journale-d therein, a yoke pivoted to said frainc above said roll with one arm disposed towards said roll, a tensioning plate carried by said arm, and a counterweight pivoted to said frame to lie against the other arin of said yoke and constantly urge said tensioning,- plate against said roll at all surface dialneters thereof.

G. ln combination, a frame, a roll journaled therein, a rock shaft journaled in said frame above the axis of rotation of said roll, a yoke hung from said rock shaft, a removable tensioning plate carried by one of the arins of said yoke and disposed to ear against the supply roll, and a removable counterweight pivoted to said frame and disposed to bear against the opposite arni of the yoke and constantly' rock the yoke towards said roll, whereby to cause the tensioning plate to bear against said roll at all surface diameters thereof.
