POSITIVE SHUTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 323,738, dated August 4, 1885.

Application filed March 6, 1584. (No model.)

T all whom it may concern.-

Be it known that I, CHARLES B. RUMsEY, of Homer, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Positive Shuttle-Motions for Looms; and I do hereby declare the following to be a full, clear, and exact deseript-ion of the same, reference being had to the accompanying drawings, forming a part of this IO specification, and to the figures and letters of reference marked thereon.

In said drawings, Figure 1 represents afront elevation of a portion of a loom showing the application of my improvements thereto. Fig.

2 is a side elevation of the same, and Fig. 3 is a top plan view of the shuttle-frame and shuttle-carrier arms.

Similar letters of reference in the several figures indicate the same parts.

The letter A indicates a portion of the main frame of the loom and B the lathe, hinged at its upper end to the main frame, and having a back-and-forth motion imparted to it by means of a suitable rod or pitman, 0, connected to and operated by a rotating crank, D, located on a shaft journaled in the main frame and rotated through'the medium of a pulley belted to any suitable prime mover, or otherwise.

The lower portion,B,of the lathe-frame carries the reed-dents C, and its extended ends are provided with suitable guides, E E, for sustaining and guiding shuttle-carrying arms F F.

Any suitable positively-acting devices may be employed for transferring the shuttle automatically from one shuttle-carrying arm to the other; but I prefer to employ the arrangement shown, as I have practically tried it and find it very efficient. It consists, essentially,

of spring-operated clutches H H, located on the shuttle-carrying arms F F, which are further provided with sockets in their ends, into which the projections g g of the shuttle-frame 5 G are adapted to enter; and, secondly, of a shuttle-frame provided with a lateral arm, g, having inclines g and a central rib or projection, the clutches H H being adapted to alternately disengage each other from this projection and become themselves engaged 5o therewith, thus carrying the shuttle-frame from one end of the latter to the other.

To the outer ends of the shuttle-carrying arms pitmen I I are connected, and these pitmen are in turn jointed to crank arms J J, 5

secured to or formed with gear-sectors K K, mounted 011 the front of the vibrating lathe,

as shown in Figs. 1 and 2. The gear-sectors are meshed together and move simultaneously and positively in opposite directions when motion is imparted to either of them, thereby giving opposite motion to the two crankarms. One of the gear-sectors is provided with a fixed cam, L, to which are connected two chains, M N. The chain M is secured to the extremity of the cam, as shown at m,passes thence over a guide sprocket-wheel, m, on the lathe, thence down behind the latter, thence around a guide-pulley, m, and thence forward to an eye, at, fastened to the stationary main frame A of the loom. The chain N is connected to the opposite extremity of the earn,

as shown at a, passes thence over a guide sprocket-wheel, n, on the lathe, thence down and around a guide'pulley, n", and thence rear- 7 5 ward to an eye, a on the stationary main frame, all as clearly shown in, Figs. 1 and 2. From these connections it follows that when the lathe is vibrated outward by the action of the crank and connecting-rod C D the chain M will be slackened and wound up 011 the cam, while the chain N will be drawn taut and grad ually unwound from the cam, so as to cause the cam to be rotated in the direction indicated by the arrow, Fig. 1.

By the rotation of the cam the connected gearsectors are simultaneously rotated in opposite directions, and through the cranksJ J and connecting-rods I I operate to force the shuttlecarrier arms apart and to opposite ends of the lathe. The inward movement of the lathe causes a reverse action of the parts. It will thus be seen that the vibration ofthe lathe back and forth effects the automatic action of the shuttle-carrying and shifting devices, the means employed to effect this action being very simple and not liable to get outof order.

My improvements are especially designed for use in connection with wire-weaving looms, though applicable to looms for weaving other fabrics.

I have not claimed herein the construction of the shuttle and the devices shown and de scribed for transferring the shuttle from one shuttle-carrying arm to the other, as I have made these inventions the sul: iect-n1atter of an application filed simultaneously herewith, and numbered 123,200.

Having thus described my invention, I claim as new-- 1. A vibrating lathe and means for impart ing motion to it, reciprocating shuttle-carrier arms mounted on the lathe, crank-arms also mounted on the lathe and geared together so as to vibrate simultaneously in opposite directions, connections between the crank-arms and shuttlecarrier arms, and means, substantially as described, for vibrating the cranks by the back and forth movements of the lathe, as set forth.

2. The combination of the stationary 100mframe, the lathe, and means for vibrating it, the reciprocating shuttle-carrier arms,the gear sectors geared togetl1er,and provided with the cranlearms, the connecting-pitmen, the cam on one of the seetors,andthe chains connected to the cam and to the stationary loon'i-frame, substantially as described.

3. The combination of the stationary loomframe, the lathe, and means for vibrating it, the shuttle carrier arms, the gear sectors geared together and having the crank'arms, the pitmen connecting the crank-arms to the shuttle-carrier arms, the cam on one of the gear-sectors, the two chains connected at one end to the cam and at the other to the stationary frame, and the several guide Wheels and pulleys, substantially as described.
