1,126,391. 7 Specification of Letters Patent Patented J an. 28, 11915.

Application filed May 20, 1914. Serial No. 839,861.

To all whom it may concern 7 Be it known that I, Ancns'rm J. Guevar'r'ra, a citizen of the United States, residing at \Vorcester, in the county of \Vorcesshuttle box.

It is the object of my invention to provide an improved construction in devices of this character, combinmg efliciency of ally mounted at 16 upon av bracket secured to the lay 10. The stud 17 which constitutes a part of the ball-and-socket connection 14 is threaded and is provided with nuts 18 by which the relation of the binder to the arm may be varied. The other end of the lever 15 comprises a substantially semicircular arm 15", formed integral with the arm 15 the outer extremity by the arm 15* being positioned at the rear of the lay. The arm 15" is connected by toggle links 20 and 21 .to a stud 22 fixed in the lay. The link 21 is provided with a rearwardly extending arm 23 positioned to contact with the end 15 operation with simplicity of parts and econof a sliding rod 21. Y

The exact presto the arm 15* of a curved lever 15 pivotsure of the binder upon the shuttle may be regulated by the use of the adjusting nuts 18. By the provision of the universal joint 14, the binder is permitted to angularly adjust itself with relation to the shuttle so that a perfect binding contact may be secured.

Having thus described my invention it will be evident that changes and modifications can be made therein Without departing from the spirit and scope of the invention as expressed in the claims, and I do not Wish to be limited to the specific details herein disclosed, but

What I do claim is 1. In a loom, in combination, a lay, op erating means therefor, a binder on said lay, a lever mounted on said lay and pivotally connected to said binder, means to positively lock said lever against the outward pressure of said binder, and connections from said operating means to said locking means, whereby said locking means is alternately moved into and out of locking position.

to one end of said lever, a toggle connected to the other end of said lever and to the lay, yielding means for closing said toggle, and positive means for breaking said toggle.

4. In a loom, in combination, a crank arm, a binder, a lever adjustably connected to said binder, a substantially semi-circular arm integral with said lever, toggle links pivoted to the end of said arm and to the lay, yielding means for closing said toggle, and means positively actuated by the crank arm to open said toggle.

5. In a loom, in combination, a binder, a

lever adjustably connected to movably support one end of said binder, said binder being free to rock in any direction on said lever, and means to periodically and positively lock said lever against outward pressure of said binder.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
