JOSEPH T. CYR, OF W'GRCESTER, MASSACHUSETTS.
LOOlVI.
Application filed September 13, 1915.
To all whom it may concern:
Be it .known that I, Josnrrr T. CYR, a citi- Zen of the United States, residing at W orcester, in the county of Worcester and State of lVIassachusetts, have invented a new and useful Improvement in Looms, of which the following is a specification.
This invention relates to a let-ofii for looms.
The object of my invention is to provide a let-otf for looms that will maintain the same uniform tension on the warp until the warp is entirely depleted.
With this and other objects in view my invention consists in certain novel devices, combinations and arrangements of parts as will be hereinafter described and more specifically pointed out in the appended claims.
In the accompanying drawing I have shown my invention attached to a portion of a loom-side sufiicient to enable those skilled in the art to understand the construction and operation thereof.
Referring to the drawing :-Figure 1, is a side view of a rear portion of a loomside with my improvement attached thereto. Fig. 2, is a view corresponding to Fig. 1, but shows some of the parts in a different position.
In the accompanying drawing is the loom-side having mounted therein the shaft 11 of the warpbea1n, said warp-beam hav ing the usual beam-head 12 secured thereto.
13 is a stand secured to the loom-side 16 and has secured therein a stud 14 upon which is loosely mounted the bearing of the casting 15.
In a projection 15 of the casting 15 is loosely mounted a stud 16, the upper threaded portion of which adjustably engages a casting 17. The portion 17 of the casting 17 has secured thereto one end of the usual brake band 18 which partially encircles the usual flange portion 12 of the beam-head 12. The opposite end of the brake band 18 is secured to a casting 19 having its bearing loosely mounted on a stud 20 secured in the stand 13.
21 is a casting loosely mounted on a stud 22 secured in the stand 13, said casting 21 has loosely mounted therein a plunger 23, the upper yoke-shaped portion 23 of which has loosely mounted therein, on a stud 24-, a

Serial No. 50,310.
shaped arm 15", of the casting 15, by a spring 26 encircling said plunger 23 and having a bearing at one end against the casting 21, the opposite end of said spring 26 having its bearing against a collar 27 secured on the plunger 23.
28 is an auxiliary warp-roll having its shaft portion 29 loosely mounted in an arm 21 of the casting 21.
30 is a connecting link having one end loosely mounted on a stud 31 secured in the casting 21, the opposite end of said link 30 is loosely mounted on a stud 32 secured in the weight-arm 33. Said weight-arm 33 is pivoted at 33 to an upwardly extending arm 13 of the stand 13. Mounted on the outer portion of the weight-arm 33 is a loop-head 34 which has attached thereto, at its lower portion, in this instance, a weight-spindle spring 35. 36 are the weights carried on said spring and are retained in position by means of a stud 37 inserted into the lower portion of the spring 35.
38 are the warp threads contained on the warp'beam and passing under the roll 28 and over the warp-roll 39, said warp-roll 39 having its shaft portion 40 loosely mounted in a stand 41 secured to the loom-side 10, the warp 38 then passes into the loom in the usual and well known way.
I will now briefly describe the operation of the above mechanism, which it will be understood may be applied to either one or both sides of a loom.
When the warp-beam is full, as shown at Fig. 1, the roll 28 is retained in its lower position by means of the required weights 36 applied on the spindle spring 35, these weights 36, through the lever 33 and con-' nector 30, retain the plunger roll 25 in its outer position on the arc arm 15. It will readily be seen that the action of the warp, being withdrawn from the warp beam, through the above described mechanism will produce the greatest tension on the brakeband 18. As the warp becomes nearer depleted, as shown at Fig. 2, and the beam requires a greater revolution to allow the proper amount of warp to be withdrawn, the roll 28 and weights 36 will be gradually carried upward, causing the plunger roll 25 to travel inward toward the pivot of the arm 15, by the action of the warp, being withflanged roll 25. The roll 25 is retained in .drawn from the warp beam, through the its outward position and against the areabove described mechanism, the tension on the brake band 18 will gradually be released thereby retaining a uniform tension upon said Warp.
Having thus described my invention it will be evidentthat many changes and modifications may be made therein by one skilled in the artwithout departing from the spirit and scope thereof and therefore, I do not Wish to be limited to the specific details herein disclosed, but,
What I claim is 1; A let-off for looms, including, in combination with the main warp-beam and brake-band or strap for the shaft thereof, a pivoted areuate arm provided with an outstanding projection, a stud loosely mounted in the latter, an element adjustably connected to said stud, said brake-strap being connected to said adjustable element, a pivotally inounted element, having loosely and resiliently mounted therein a plunger, said plunger being equipped to engage said arcuate pivoted arm, said pivotally mounted element also having an arm equipped with a Warp-guide rotary member, and a weight control for the aforesaid parts.
equipped with a warp guide rotary member,
a weight-controlled element, and a link-connection between said weight-controlled element and the pivotally mounted element connected to said loosely mounted plungercarrying element.
In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
