LOOM.

SPECIFICATION forming part of Letters Patent 0.550,405, dated November 26, 1895.

Application filed .Tune 26, 1895. Serial No. 554,071. (No model.)

T0 a/ZZ whom t may concern:

Be it known that I, WILLIAMOAVANAGH, ofthe city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Open-Shed Fancy Looms; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in open-shed fancy-looms; and it consists in the peculiar and novel construction of mechanism for stopping the loom and operating the evener-slide, as will be more fully set forth hereinafter.

In open-shed fancy-looms when a warpthread breaks or ends require to be tied in the harnesses require to be evened, so as to lay the warp side by side and enable the operative to piece up the warp or tie in the ends required. In such looms as they are at present constructed this' requires much care and time.

In such looms as heretofore constructed the evener-slide had to be drawn out by hand after the lay was brought into the proper position, and then the harnesses had to be brought together by hand. After the ends were tied in the parts had to be returned to their original positions by hand before the loom was ready to start.

The object of the present invention is to perform all these operations automatically through setting in motion a simple apparatus connected with a cordl extending practically around the loom by pulling the cord.

To enable others versed in the art to more clearly understand and practice my invention, I will describe the same more fully inconnection with the parts of an open-shed fancy loom with which the mechanism co-opcrates.

Figure l is a skeleton View of parts of an open-shed fancy-loom, showing the improvement connected with co-operatingparts. Fig. 2 is a perspective view of the levers connecting with the crank-shaft of the lay of the loom. Fig. 3 is a side View of a modified form of the device.

Similar letters of reference designate corresponding parts throughout.

In the drawings, A indicates the lay of an open-shed fancy loom; B, the connecting-rod connecting the lay With the crank of the shaft C. The shipper or stop-lever D is secured to the shipper or stop-shaft E, and supported in the raised frame F is the evener-slide T.

The parts so far described are the essential parts of every open-shed fancy-loom. As my improvement concerns only these parts, the other parts of the loom are omitted, so as to avoid confusion and'to point out the improvement more clearly.

The preferred means for carrying out my invention consists in the lever g, loosely mounted on the shipper-shaft E close to the shipperlever D. The upper projection of the lever g is provided with the pin g', bearing on the shipper-lever D. To the lower end of the lever g is pivotally connected the arm h, the other end of this arm h being provided with the shoulder h. The arm h is supported in the slotted bracket e', preferably secured to the end frame of the loom, as is shown in Fig. l. The bracket la is secured to the arm h, and near this is the eye l, to which the cord lrnl is fastened. This cord m is carried over rolls or other guides along the end around part or the whole of the loom, the end of the cord being secured to any fixed place, preferably a part of the loom, and at such a height that it does not interfere with the work of the operative or the loom and is within easy reach of the operative.

On the crank-shaft C the wiper-cam n is secured so as to rotate with the crank-shaft. The shoulder n of the wiper-cam nis designed to engage with the shoulder h on the end of the arm h when this arm is raised. Close to the cam n and also secured to the crank-shaft C is the cam o, provided with the shoulders o and o". The evener-slide T is provided with the slotted head p. The lever q, pivoted to the bracket r, secured to the frame F, is provided at its upper end with a pin s, whichextends through the slot in the head p on the evenerslide T. To the lower part of the lever Q is connected pivotally the arm u, which extends through the slot in the bracket e', and is provided at its free end with two shoulders u and u. To the arm u, on its under side, is secured the bracket o.

In the normal condition, when the loom is running, the arm h rests in the slotted bracket z' and supports, by means of the brackets k IOO i tie in ends or piece the warp, the loom requires to be stopped and the warp evened, instead of performing the operations required in an open-shed fancy loom as herein first described, the operative pulls on the cord m and raises the arm h, the shoulder n' of the cam n comes in contact with the shoulder h and pushes the arm 7L and the lower end of the lever i g forward, and the pin g operates the shipperlever D to stop the loom. In the movement of the arm 7L the bracket 7c passes beyond the bracket fu, the arm u descends, the shoulder o' of the cam o encounters the shoulder u' of the arm a and draws this arm rearward and with it the lower end of the lever q, the upper end of which draws the evener-slide sidewise and, as it is supported on pins entering `diagonal slots, it raises the evener-slide and operates the harnesses to even the warp in the usual manner and by the lold well-known means.

After the piecing is completed the lay A is pushed back, thus partly rotating the crankshaft C and cam o, the shoulder oll comes in contact with the shoulder u and pushes the i arm a, with the lower end of the lever q, forward and the even erf-slide T inward and downward into the original position. The shipperlever D is new drawn forward to sta-rt the loom, and, by coming in contact with the pin g', the lever g pushes the arm 7L backward, the bracket 7o, coming in contact with the bracket o, lifts it and the arm u and supports the same in the position shown in Fig. 2. rangement the pull on the cord 'm sets the mechanism in operation to stop the loom and even the harnesses, and a push on the lay puts the loom in condition to be started by the shipper-lever.

While the arrangements of the various parts of my improved mechanism have been found in practice to accomplish the desired result, I do not wish to confine myself to the exact construction shown.

In the modified form shown in Fig. 3 the p arm h is connected by the lever e with the arm a3, which is pivoted to the lever q. The lever 4f is pivoted in the slot of the bracket t" and only the cam n is secured to the crankshaft C. In this modified form the cam n will have to be accurately adjusted, so that the shipper motion to stop the loom and the movement of the evener-slide will correspond with the movements of the harness-operating mechanism.

The parts of my improved mechanism used for operating the shipper-lever may be used on other kinds of looms.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- By this arl. In an open-shed fancy loom, the combination with the shipper-lever, the lay-crankshaft, and the evener-slide, of a wiper secured to the lay-crank-shaft, an arm suspended near one end below the wiper and connected at the other end with a lever loosely mounted on the shipper-shaft and said lever constructed to engage with the shipper-lever, a cord connected with and adapted to raise the end of the arm suspended below the wiper, a pivoted lever one end of which is connected with the evener-slide, an arm pivotally connected with the opposite end of the pivoted lever, and connections between the two arms constructed to support the upper arm the whole adapted to operate the shipper-lever and the evenerslide, as described.

2. In an open-shed fancy loom, the combination with the evener-slide, of a lever, pivotally supported on the frame, connected at its upper end with the evener-slidc, an arm pivotally connected with the lower part of the lever, a wiper-cam secured to the lay-crankshaft, a hand-operated device for engaging the pivoted arm and the wiper-cam, and mechanism, substantially as described, between the pivoted arm and the wiper-cam, adapted to operate the evener-slide, as described.

3. The combination with the lay cra-nkshaft and the shipper-lever of a loom, of the lever g connected with the ship per-lever, the arm 7L pivotally connected to the lever g at one end, the wiper-cam n secured to the laycrank-shaft, and the cord m, secured at one end to the arm 7L, extending over supports and having the other end secured to the loomframe, constructed to raise the end of the arm 71, into engagement with the wiper-cam to stop the loom, as described.

4. In an open-shed fancy loom, the combination with the shipper-lever D, the lever g mounted on the shipper-shaft the lay-crankshaft G and the evener-slide T, of the wipercam n secured to the lay-crankshaft, the arm h one end of which is supported by the cord m and the other connected with the lever g, the cam o having shoulders o oH also connected with the lay-crank-shaft, the arm a provided with the shoulders a', u adapted to engage with the cam shoulders o and o, connections between the arm u and the evenerslide T, and connections between the arnrh and the shipper-lever D, and the cord m; the whole constructed to automatically operate the evener-slide and shipper-lever when the cord is pulled so as to raise the arm 71., as described.

In witness whereof I have hereunto set my hand.

WILLIAM CAVANAGII.
