TENSION DEVICE FOR SPOOLING-MACHINES.

Specification of Letters Patent.

' Application filed August 14, 1919. Serial No. 317,511..

To all whom it may concern.

Be it known that I, FREDERICK JARRY, a citizen of the United States, residing at New. Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Tension Devices for Spoolin geMachines, of which the following is a specification. I

This invent-ion relates to certain new and useful improvements in tension devices for spooling machines, and the primary object of the invention is to provide a rolling or rotatable tensioning means and to also pro vide means for adjusting the tension of the rolling means as desired. The invention further aims to provide a simple and effective structure involving a. minimum of parts easily accessible and unlikely to be easily deranged. 7 v

Briefly. the invention. proposes arotatable or turnable roller over or around which the thread passes and a deviceunder the influence of an adjustable counterweight or the equivalent for placing the axle 01' supporting shaft of the roller under adjustable tension. 1

In the drawings, -illustrating an embodi-, ment of the invention,

Figure 1, is a top plan view;

Fig. 2, is a side elevation; and

Fig. v3, is a section taken online 33 of Fig. 2. v I

In proceeding in accordance with the present invention a rollerl, is rigidly mounted on or in rigid connection with a. supporting shaftor axle 2 the latter mounted in a journal 3, the journal being here shown, by way of example as carried by a standard extend I ing upwardly from a base 5. The journal is provided with a cut-out 6 which at one end communicates with the axle 2 and is radial to the latter. A brake block or friction shoe 7 is slidably mounted in the cut-out 6 andis guided by the walls defining the latter. The block at its inner end is grooved at 8 to conformably receive the axle and is similarly rooved at 9 at its outer end to receive a lever rod 10 which latter is pivoted at 11 to a vertical arm 12. Arm 12 is offset from its lower part 12vthe latter being projected through the journal. The grooves 8 and 9 are disposed at a right angle to each other and likewise the axle and lever rod 10. A counterweight 13 is adjustable along the lever'lO, so as to vary the tension on the ingaction of the shoe on the axle.

An eye ll is carried by the base and located onone side of the roller 1, while a.

.latter and once around the roller 1 and thence under the hook 15, to the spool adjacent the hook. the tension being created by the braking action or force o'f the shoe 7 which retardsxrotation of the roller axle according to the position of the weight.

As is obvious ,fromthe foregoing, a simple and. econon'lical structure is provided in which vthe shoe may be removed and-replaced by simply lifting same subsequent to disengagement of the lever rod therefrom.

What is clain'ied is Y 1. In a tension device for spooling machines, a journal having acut-out therein, an axle in the journal communicating with the cut-out. a braking shoe slidable in the cutout and having a groove on its inner end receiving the axle and a groove on its outer end at right angles to the first named groove,

an arm on the journal, a counterweighted lever pivoted to the arm and engaged in said groove of the outer end of the shoe, a thread engaging roller on the axle, and thread guiding'members on opposite sides of the, roller and located therebelow. j

2. In a tension device for spooli-ng machines, an axle, a yarnengaging roller borne by the axle, a friction shoe engaged at one end with the axle, means to slidably mount the shoe, a pivoted lever bearing between the ends thereof on the opposite end of the shoe, and a weight adjustable on the lever.

- 3. In a tension device for spooling machines, an axle. a yarn engaging roller borne by the axle, a friction shoe engaged at one end with the axle. meansto slidably mount the shoe, a pivoted lever bearingbetween its ends on the opposite end of the shoe, and means to adjustably tension the lever.

at. In a tension device for spooling machines, an axle, a yarn engaging roller on the axle, a friction shoe of bar-like form, means to mount said shoe to allow same to slide radially of the axle and to bear. at one end on the latter, and means engaged with the Patented Jan. 27; 1920.

'55 shoe 7 and accordingly the tension or brakother end of the shoe to adjustabl'y tension the latter.

5. In a tension device for spooling inaehi-nes, an axle, a yarn engaging roller on the axle, a friction shoe of bar-like form, means to mount said shoe to allow same to slide radially of the axle and to hear at one end on the latter, and a lever pivoted at. one end and counter-weighted at its opposite end. said lever overlying the shoe and bearing thereon at a point intermediate of its ends, whereby the shoe may be slid out of engagement with the axle by swinging of the lever out of en- 'gagenient With the shoe.

the cut-out and havingits inner end hearing.

on the axle, and means engaging the-outer end of the bar-like shoe to tension the same. In testimony whereof I. affix my signature.
