HAND-LOOM.

SPECIFICATION forming part of Letters Patent No. 234,761, dated November 23, 1880.

Application filed March 23, 1880.

To all whom it may concern:

Be it known that I, CALVERT A. FISH, of the city, county, and State of New York, have invented a new and useful Improvement in Hand-Looms, of which the following is a specification.

The object of my invention is to fit a handloom of usual construction with mechanism whereby it may be driven by power.

The first part of my invention relates to means for giving a forward and backward movement to the lay or batten, and the second part to the means for automatically throwing the shuttle; and my invention consists of a bar fitted to slide on rollers beneath the batten to which the bar is attached, said bar being connected by cords with the treadle, so that the batten is vibrated by the movement of the treadle; also, in spring-ratchets and pawl devices connected with the picker-stafis, and operated by cords from the batten to throw the shuttle. These features will be described in detail with reference to the drawings, wherein Figure l is a front elevation of a loom embodying my improvements, and Fig. 2 is a side view of the same; Fig. 3, a sectional detail, showing the catch at the lower end of the batten.

Similar letters of reference indicate corresponding parts.

A is the frame of the loom; B, the lay or batten; 0, the shuttle -race; 1) D, the shuttleboxes, hung on the levers f for movement by the jacquard-cards, and E E are the pickerstaft's, connected at their upper end by the spring 6. These parts are of the usual construction, and there may he one or more shuttles, as desired.

F is a bar supported beneath the batten B on rollers a, that are hung in frame A, and connected by a spring-catch, I), with the batten.

The catch 1) consists of a spring-tongue fixed on bar F, and formetl with a groove or mortise for receiving the lower rail of the batten. This construct-ion permits the tongue to follow the curved movement of the batten and retain its hold.

(1 is a cord connected beneath bar F at its of the shuttle.

(No model.)

mid-length, and passing in opposite directions over rollers a to the treadle g, to which the cord is connected, one end passing beneath a friction-roller, h, so that by a rocking motion of the treadle a horizontal reciprocation will be given to bar F and the batten vibrated.

i "L are ratchet-disks or cams hung on studs or pins on the side bars of the batten B.

It It are pawl-arms hung on the picker-staffs E, and engaging by their hook ends with the ratchets 27.

l l are staples on the breast-beam of the batten, secured over the pawls 70, for supporting and guiding them.

an m are cords connected with the ratchets i, passing beneath friction-rollers a a on the batten B, and connected at the sides of frame A.

0 0 are springs connected with ratchets i, for purposes hereinafter described.

\Vith the lay or batten having a movement of twelve inches, and the picker-staffs fitted to travel at their moving end a distance of twelve inches, the pawls It will be connected one inch from the fulcrums of staffs E, so that a movement of one inch by the pawls will give the requisite movement of the picker. The cords m on will be of such length from the rollers to their connection to frame A that they shall not be tightened by the vibration of the batten until it has moved over a distance of ten inches.

the staffs inward with a quick movement to throw the shuttle. Before the batten has completed its movement, the rotation of the ratchets releases the pawls 7t, and the spring Zinstantly carries the staffs back out of the way On the return movement of the batten, the cords m are slackened, the ratchets i are turned back by the springs 0, and engage again with the pawls 7r. By these means the batten is vibrated and the shuttles thrown at theproper time by movement of the treadle g, which movement may be obtained by power in any desired manner.

I have shown a rod,p, hung on treadle g, which rod may be connected to the crank of a driving-shaft for moving the treadle.

I do not limit myself to the devices exactly as shown and described, as various modifications may be made in the construction and arrangement of parts.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. In combination with the lay or batten B, the bar F, connected with the lay, rollers a, the cord d, and treadle g, constructed for operation substantially as and for the purpose set forth.

2. In combination with the vibrating lay B 15 OALVERT A. FISH.
