PlCKER-CHECKING MEANS FOR LOOMS.

SPECIFICATION forming part Of Letters Patent No. 729,048, dated May 26, 1903.

Application filed October 17. 1902. Serial No. 127.670. (No model.)

If 0 all whom it may concern.-

Be it known that I, ARTHUR EAVES, a citizen of the United States, and a resident of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Picker-Checking Means for Looms, of which the following description, in connection with the accompanying drawings, is a specification,1ike characters on the drawings representing like parts.

This invention relates more particularly to picker-checking means for looms; and it has for its object the production of novel and simple means for very efiectively checking the outward movement of the picker when the shuttle enters the shuttle-box.

The various novel features of my invention will be fully described hereinafter and particularly pointed out in the following claims.

Figure l is a front elevation of one end of the lay of aloom and the shuttle-box thereon with one embodiment of my invention applied thereto. Fig. 2 is a top or plan view of the mechanism shown in Fig. 1. Fig. 3 is a top or plan view of the shuttle-binder detached to more clearly show the picker-check carried thereby, and Fig. 4. is a rear elevation of the binder and picker-check.

The lay A having a shuttle-box thereon comprising a front plate I), back plate or wall I), shuttle-guard or top plate 11 the binder B ,pivotally mounted near its outer end upon the lay at b the spring-controlled protectorshaft 1), and the upturned finger 19, carried thereby and bearing against the free inner end of the binder, may be and are all of usual or well-known construction and operate in the usual manner. The lay is shown as longitudinally slotted at A Fig. 2, for the staff of the usual picker P.

As shown in Fig. 2, the swell 2 of the binder extends into the path of the shuttle when the latter is not in the box, and the impact of the entering shuttle throws or swings the free end of the binder out against the usual spring, (not shown,) the greater the impact of the shuttle upon the binder the greater the outward movement of the latter. In accordance with the illustrated embodiment of my present invention this shuttle-induced movement of the binder is made efiective to actuate a pickercheck and thereth'rough check the outward throw of the picker, thus preventing rebound of the shuttle in the box.

The picker-check is shown as an elongated hook-like memberoo, the side 0' thereof being bent at o c and secured to the back face of the binder by suitable means, as screws 5, Fig. 4, so that the side 0 extends longitudinally parallel to and preferably just within the path of movement of the outer side of the picker P, so that there will be frictional engagement therebetween.

I prefer to make the check resilient, and it is conveniently made of a metal strap of requisite size and stiffness, the inner end of the side 0 of the check being bent out or flared, as at 0 I As shown clearly in Figs. 1 and 2, the member c 0 extends beyond the outer pivoted end of the binder to afford ample room for the movement of the picker and presents a horizontal U-shaped hook, into which the picker enters on its outward throw, the distance between the sides a 0 being great enough to preventthe side 0 from engaging the rear face or side of the picker. When the incoming shuttle strikes the swell 2 of the binder, the latter is thrown outward,swinging on its fulcrum b and the checking member is moved thereby, so as to project the side 0 thereof a greater or less distance inward within the path of the front side or face of the picker, the flared inner end 0 of the check. member 0 first engaging the picker on its outward stroke. The pressure thus exerted upon the picker by engagement with the check acts to frictionally retard and check the picker, so that it will gradually slow down as it reaches the end of its outward stroke, the resiliency of the check permitting it to flex as the picker moves along.

It will be obvious that the greater the impact of the entering shuttle upon the binder the greater will be the quick outward throw of the latter, and consequently the greater will be the pressure exerted upon the picker by my novel picker-check, the pressure or retarding action exerted thereby thus being proportional to the speed of the incomingshuttle.

By engaging only one side of the picker IOO there is no Wedging action upon it, and it is the more readily and quickly freed when the shuttle is thrown from the shuttle-box.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom, the lay having a shuttle-box, a binder, a picker, and an elongated hooklike friction check mounted on the binder, shuttle-induced movementof the binder caus ing the check to engage the picker with a pressure proportional to the force with which the incoming shuttle strikes the binder.

2. In a 100m, the lay having ashuttle-box, a binder, a picker, and an elongated, resilient checking member fixedly mounted upon the binder and longitudinally extended adjacent and substantially parallel to the path of movement of the picker, said checking member being brought into operative engage- ARTHUR EAVES.
