LOOM ATTACHMENT.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed. October 8, 1913. Serial No. 794,102.

To all whom it may concern Be it known that 1, IGNACE COULOMBE, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Loom Attachments, of which the following is a specification.

My invention is an improvement in loom attachments, and has for its object to provide an attachment of the character specified, wherein the tension on the warp beam is controlled directly by the weight of the yarn on the bea-m, and wherein t-he mechanism is so arranged that as the yarn feeds from the beam, the tension will automatically decrease.

'In the drawings z--Figure 1 is a front view of a portion of a loom, showing the warp beam with the attachment in place, Fig. 2 is an end view of Fig. 1 with parts of the loom broken away, Fig. 3 is a top plan View of the lever mechanism, and Fig. 4 is a perspective view of the bearing levers for the spindle or journal pin of the warp beam.

The present invention is an improvement l over my priorfpatent #1,062,443, granted May 20, 1913.

. The warp beam 1 of the loom 2 is provided with the usual spindles or journal pins 3, and the said pins engage grooves 4 and 5 respectively in bearing levers G and 7 rlhe said levers are pivoted intermediate their ends between the arms 8 of a fork at the upper end of the standard 9, by means of a pivot pin 10. The pin passes through the arms of the fork, and the levers, and a cotter pin 11 is provided for holding the pin in place. The lever 6 has the end remote from the Ofroove 4 offset laterally away from the leveiD 7 as shown at 12, and both levers are provided at the said end with

openings

13 and 14 respectively.

It will be understood'that the mechanism at each end of the loom is the same, and each of the standards 9 before mentioned. is connected to one end of a plate 15, which is secured to the frame of the loom by means of screw bolts 16, the said screw bolts passing through slots 17 extending longitudinally of the plate, in order that the plates may be adjusted to proper posit-ion with respect to the loom.

Levers

18 and 19 are connected with the plate. The lever 19 is provided at the end remote from the standard with a hub or bearing 20, and the said hub or bearing engages a pin 21, extending laterally from the plate, and a cotter pin 22 is passed thro-ugh the pin outside of the lever to hold the lever in place. The lever 18 is pivoted on a pin 23 extending laterally from the plate, and a sleeve or arbor 24 encircles the pin between the lever and the plate 15.

A cotter pin '25 is passed through the pin outside the lever. Each lever is slotted longitudinally, the lever 18 having a slot 26, and the lever 19 having a slot 27. A bolt 28 is passed through the slot 27 of the lever 19, and a nut 29 is threaded on to the bolt adjacent to the said lever. is on the inner side of the lever, and the outer end of the bolt engages the slot 2G of the lever 18. Thus the bolt may be adjusted with respect toboth levers, and may be locked in adjusted position by tightening the nut to compress the lever 19 between the head of the bolt and the nut. r1`he lever 18 y'is extended beyond the pivot pin 23 toward the standard, and the said end is provided with an opening 30, and with a slot 31, leading from the opening to the adjacent end of the lever. v

The brakedisk 32 at each end of the beam isengaged by a brake band 33 of any usual or desired construct-ion. One end of the brake band is connected to a laterally eX- tending pin 34 on one of the arms 35 of an elbow lever. The other arm 36 of the said lever is connected to the opening 14 of the bearing lever 7, by means of a chain 37 or the like.

r1`he elbow lever is pivoted intermediate its ends on a pin 38, extending laterally inward from the standard 9, and a cotter pin 39 is passed through the pin to hold the elbow lever in place. The opening 13 of the lever 6 is engaged by one end of a chain or other flexible member 40, and the opposite end of the chain is connected to the free end of the lever 19.

A rod 42 connects the other end of the brake band with the lever 18. The rod is provided with a hook 43 at its upper end and the lower end passes through the opening 30 of the lever 18, and a wing nut 44 is threaded on to the rod below the lever.

The operation of the attachment is as follows When the beam is heavy with yarn, the weight of the beam and the yarn tends r1`he head of the bolt to depress the inner ends of the bearing levers, and to raise the outer ends. The lever 6 when the outer end lthereof is raised, will lift the arm 36 of the elbow lever, thus making tension on the end of the brake band connected with the arm 35 of the said lever. At the same time, the outer end of the lever 7 is lifted, thus making tension on the chain 40, and tending to lift the end ofv the lever 19 adjacent to the standard 9. Since the

levers

18 and 19 are connected and since the connection is on the opposite side of the pivot pin 23 from the chain 40, the end of the lever 18 remote from the standard 9 is lifted, thus depressing the end connected with the rod l2 and making tension on the other end of the brake band. yarn passes from the warp beam, the weight of the beam and the yarn is lessened, so that there is less downward pressure on the inner ends of the levers 6 and 7, and as a consequence the tension on the brake band is decreased. The connection between the brake and the warp beam is very sensitive, responding` instantly yto every change in weight however slight. rlhus the actual weight of .the warp on the beam controls the tension. After the proper relation between the

levers

18 and 19 is attained, no further adjustment is necessary. The adjustment may be so exactly arranged, that the actual tension on the warp beam will be the same, from the commencement of the feeding of the warp until the last coil is withdrawn. -By arrangingfthe brake at each end of the beam, the device is muc'h more sensitive, and much more exact. In different characters of warp, the connection between the levers may be varied, so that whatever the character of the' warp, the tension will be precisely the same until'all of the warp is unreeled from the beam.
