SPECIFICATION forming' part 0f Letters Patent N0. 680,778, dated August 20, 1901. Application filed May 14, 1901. Serial No. 60,233. (No model.)

To all whom t may concern,.-

Be it known that I, OSCAR JANELLE, a citizen of the United States, residing at Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

1o This invention has for its object the production of novel means for preventing rebound of the shuttle when it enters the shuttlc-box of a loom.

Various novel features of my invention will be hereinafter described, and particularly pointed out in the following claims.

AFigure lis atop or plan View, partly broken ont, of the left-hand end of the lay of a loom with one embodiment of my invention ap- 2o plied thereto. Eig. 2 is a rear elevation of the parts shown in Fig. l; and Fig. 3 is a right-hand end elevation of the lay and adjacent parts shown in Fig. 2, with a part of the picker-check broken out.

I have herein shown the lay A3 as having a shuttle-box thereon comprising a front plate or wall B, back wall B', overhangng shuttleguard B2, and a binder BX, pivotally mounted near the outer end of the lay at hX, which may 3o be all of usual or well-known construction, the lay being longitudinally slotted at AX for the staff of the usual picker P. A suitable binder-spring S bears against the back of the binder and is secured to the lay at 3, and the ,35 protector rock-shaft p, mounted in bearings ,79X beneath the lay, the dagger p', rocker-arm p2, having the upturned finger p3 to bear against the free end of the binder, and the 4controlling-spring SX are also of usual con- 4o struction and operate in a Wellknown manner.

The impact of the shuttle upon the swell of the binder at the high :rate of speed of the shuttle as it enters the shuttle-box throws the binder out against the spring S and the spring SX of the protector mechanism, and before the binder can return to engage and prevent Jthe shuttle from rebounding the shuttle hits the picker and tends to bound back.

5o I have herein provided means to accelerate the return of the binder to properly check rebound of the shuttle, such means being made operative by or through the impact of the entering shnttle upon the picker.

A bracket o, secured to the lay, has bearings aX for a short rock-shaft a', having secured to it an upturned arm d2, provided with an eye a3, through which is extended a pusher, shown as a short rod d4, held in adjusted position by a set-screw 4., the front end 6o of the pusher being behind and normally out of engagement with the binder. A spring S' surrounds the shaft a between its bearings, one end of the spring being fixed to one of the bearings and the other end to a collar 5, fast on the shaft, the spring normally maintaining the parts in the position shown, a stop G on the collar engaging the lay (see Fig.

3) and limiting the rotation of the shaft a. in the direction of arrow 8. The outer end of 7o the shaft has secured thereto, preferably adjustably, by a set-screw l0 a hub co5, having a depending leg a6, Which'at its lower end is laterally enlarged to form a foot a7, extending parallel to and normally partly in the path of the picker-staff PX and beveled or dared at its inner end. (See Fig. 2.) The Vertical face of the foot is preferably covered With leather or other suitable cushioning material, as 20, and the covered foot constitutes 8o a movable buffer forming one member of a picker-check, the latter also including a fixed buffer located opposite to the movable buffer and herein shown as a suitably-shaped head ctw on the lower end of a bracket C013, secured to the lay, said head being also covered with cushioning materiaLsuch as leather or thelike 22,and the fixed buffer is also beveled or flared at its inner end, the straight vertical face of the buffer being shown as substantially 9o coincident with one side of the path of the picker-staff, the flared inner ends of the two buffers, which normally are in the position shown in the drawings and particularly referring to Figs. l and 3, constituting a Wide entrance for the picker-staff on its outward stroke. When the shuttle enters the shuttleboX, it hits the swell of the binder BX and throws the latter outward with great violence, suchmovementofthebinderbeingopposedby roo the action of the springs S SX, and the shuttle as it continues its movement toward the end of the lay hits the picker and the latter is moved with the shuttle. Such impact of the shuttle upon the picker drives the picker-staff* between the fixed and movable buffers comprising the picker-check and presses the movable buffer a7 toward the back of the loom to thereby rock the shaft a' in the opposite direction to the arrow 8, and such rocking of the shaft moves the pusher a4 forward to engage and push the binder back toward the front of the shuttle-box, accelerating its return by the quick sharp blow i mparted to it by the pusher.

The separation of the buiers against the action of the spring S' operates at the same time as a check for the picker, and the acceleration imparted to the binder on its return movement brings the binder into position to engage the side of the shuttle before the latter has had an opportunity to rebound, such engagement of the binder with the shuttle thereby checking and preventing rebound of the shuttle.

When the picker is thrown inward by any usual actuating means, (not shown,) lthe picker-staff passes out from between the fixed and movable buffers constituting the pickercheck, and the movable buffer returns to normal position, (shown in Fig. 1,) and at the same time the pusher a4 is withdrawn from engagement with the binder, so that the latter is left entirely to the control of the hinder-spring and the spring on the protector rock-shaft at the next impact of the entering shuttle.

By the construction herein shown the resistance of the binder and the impact of the shuttle are not increased, but an additional impulse is given to assist the return of the binder to operative position intime to engage and prevent rebound of the shuttle.

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

l. In a loom, the lay, a shuttle-box thereon, a spring-controlled binder thrown out by impact of the entering shuttle, the picker, a picker-check comprising a fixed and a yielding buffer, between which the picker passes when struck by the entering shuttle, and

means actuated by movement of the yielding buer to engage and accelerate the return of the binder to position to prevent rebound of the shuttle.

2. In a loom, the lay, a shuttle-box thereon, a binder, the picker, a spring-controlled rockshaft on the lay and having a inger to coperate with and resist outward movement of the binder, a second rock-shaft also mounted on the lay and having an arm to coperate with the binder, and means operated by shuttle-induced movement of the picker to rock the second rock-shaft and bring the arm thereof into engagement with the binder, to accelerate the return of the latter to position to cooperate with the shuttle.

3. In a loom, the lay, a shuttle-box thereon, a binder, the picker, a picker-check having a buffer movable by engagement with the picker, a pivotally-mounted arm on the lay and normally inoperative, and connections between the buer and arm to move the latter toward and to engage the binder to accelerate its inward movement into checking .position for the shuttle.
