SHUTTLE-BINDER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 550,596, dated December 3, 1895.

Application filed July 7, 1893. Serial No. 479,855. (No model.)

To all whom it may concern.-

Be it known that I, JAMES COWGILL, a citizen'of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Shuttle-Binders for Looms, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same and representing such portions of the loom as are nec essary to illustrate the character of my present invention.

Figure 1 represents a top view of one end of the lay of the 100m, showing one of the shuttle-boxes having a shuttle-binder embodying my invention. Fig. 2 is a front view of the same. Fig. 3 is a sectional view on line 3 3, Figs. 1 and 2; and Fig. 4 is a perspective view of the shuttle-binder detached from the shuttle-box.

Similar letters refer to similar parts in the different figures.

A denotes aportion of the lay of the loom. B denotes one of the shuttle-boxes, and O the binder, pivoted upon a stud O, with the inner side of the binder O placed in the path of the shuttle, so that when the shuttle enters the box 13 the binder C will be swung upon the stud O and the free end of the binder moved outward.

Journaled in bearings D, which are attached to the lay, is a protector-rod D, to which is attached a finger D with its end bearing against the binder O. A weighted arm D is attached to the protector-rod and extends beneath the lay, so that its weight will rock the rod and hold the end of the finger D pressed against the outside of the binder C with a uniform pressure, or in lieu of the weighted arm D a spring can be applied to rock the rod D in the usual and well-known manner. a

The binder 0 consists of a bar of wood pivoted upon the stud O and provided upon its inner side with an elastic finger E, preferably integral with the bar C and separated from it by the saw-kerf E. The finger E has its free end scarfed at E for the incoming shuttle to strike against, and the binder is held in its normal position with the inner side'E of the elastic finger lying within the path of the shuttle, so as to exert a friction upon the shuttle as it is received within the box. As the incoming shuttle strikes against the scarfed end E of the elastic finger E the finger yields slightly to the impact of the shuttle, gradually checking the momentum of the shuttle as it approaches the end of the box. The continued motion of the shuttle, however, after pressingthe elastic finger, causes the free end of the binder to be moved out, thereby rocking the protector-rod D in the usual and well-known manner.

The angular movement of the binder by which the protector-rod is rocked by means of a finger attached to the rod and resting against the binder is not new, as this operation of the binder is substantially the same as that of binders now in common use.

I am aware that it is not new to place an elastic blade upon the inner side of the binder arranged to yield slightly to the impact of the shuttle before the binder is moved out by the entrance of the shuttle, and I do not claim such, broadly. It has been customary heretofore to make the shuttle-binder of metal and attach a blade-spring by screws or bolts to the inner side of the binder.

My improved binder is made from a bar of wood and the elastic finger formed by being separated from the bar by the saw-kerf E, and forming a scarfed end upon the elastic finger to receive the impact of the shuttle. This method of construction not only renders the binder extremely cheap and simple and obviates entirely the employment of a tempered spring-blade attached by screws or bolts which are liable to become loosened during the operation of the loom, but it also provides a binder which is extremely sensitive to the impact of the shuttle and causes the momentum of the shuttle to be gradually retarded, as the resistance of the elastic finger is chiefly expended to control the action of the shuttle during the period of its impact against the scarfed end E and I have found in practice that a binder constructed and operating as herein described renders the loom capable of a considerably-mereased speed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In aweaving loom, the combination with the lay of the loom, of a bar of wood pivoted at one end upon said lay, and an elastic finger projecting from the inn er side of said bar and integral therewith, said finger having a searfed end E projecting into the shuttle box and adapted to receive the impact of the shut tle, substantially as described.

2. In a Weaving loom, the combination With the lay of the loom, of a bar of Wood pivoted at one end upon said lay, an elastic finger E projecting from the inner side of said bar and integral therewith, said finger having a scarfed end projecting into the path of the shuttle as it enters the shuttle box, a protector rod, a finger held upon said protector rod and I 5 JAMES COWGILL. lVitnesses:
