LOOM.

SPECIFICATION forming part of Letters Patent No. 600,217, dated March 8, 1898.

Application filed September 27, 1897. Serial Nol 653,098. (No model.)

To @ZZ tlf/"2,0m, it may concern,.-

Be it known that l, HENRY Ensrwoon, a citizen of the United States, residing in Lake View, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Looms; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it 1o appertains to make and use the same, reference being had to the accompanying' drawings, and to letters of reference marked thereon, which forni a part of this specification.

This invention is an improvement on United States Letters Patent No. 37 7 ,425, granted to me on February 7, 1888; and its object is to provide a loom of the character described in said Letters Patent with means for operating and controlling the series of picker-sticks, to

zo thus render said loom perfect, effective, and

reliable in operation.

The invention consists in the improved loom, in its picker-stick operating and controlling mechanism, and in the combination and arrangements of the various parts, substantially as will be hereinafter more fully described and nally embodied in the clauses of the claim.

In the accompanying drawings, in which 3o like letters of reference indicate corresponding parts in each of the two views, Figure l is a front elevation of a loom provided with my improvements, certain portions being broken away and others removed to better illustrate the nature of my said invention;

and Fig. 2, an end elevation of Fig. l, certain parts illustrated in said Fig. l not being shown. Y

In said drawings, A represents a loom, and

4o A its supporting-frames a, the driving-shaft, and a the crank-arms, connected by pitmen CL2 with the lay a3, all of the usual and wellknown construction. The said lay is supported by a series of lay-swords a4, fulcrum ed on the shaft a5, arranged in suitable brackets in the frame A and parallel with the drivingshaft a.

AtV or near the lower portions of the layswords d is secured in any desired manner a 5o cross-bar 298, (parallel with the lay,) on which are pivotally secured the lower ends of the series of picker-sticks c, the upper portions of which are connected bya series of links d and d and leather straps d2. On said crossbar bs and on each side of the loom is also fulcrumed an angle-lever DG, having its longer arm connected with the links CZ and d' and provided in its shorter arm b with an elongated slot ho, penetrated by a projection arranged on the shorter arm of the tappet-lever 6o hf, which latter is at right angles to the crossbar bs and is pivotally secured, as at b2, to a bracket, as clearly illustrated in Figs. l and 2. On the longer arm of said tappeti-lever b is secured the cam h3, adapted to be operated by its respective tappet h4, which latter is mounted on the cam-shaft h5, receiving its motion from the main driving-shaft through a train of gears, as in the usual manner.

Each angle-lever h6 is provided with a bridge 7o a0, penetrated by an arm e, pivotally secured with one end to the lay-swords a4 and provided with a shoulder e0, adapted to engage said bridge and thus lock the said angle-lever and the picker-sticks in position after the latter have been operated. The free end of each arm e is connected by a cord e to one end of a fulcruined head-lever e2, the other end of which is connected by a cord or Wire eg to a fulcrumed treadle-lever e, adapted to 8o be operated by a cam e5, mounted on the camshaft b5.

The upper portions of the picker-sticks c are adapted to operate in elongated slots arranged in the lay, while the various sets of harness are operated and controlled by a series of fulcru med levers n, in turn operated through a series of cams mounted on the shaft c6, which latter is arranged at right angles to the cam-shaft4 b5. 9c

On the shaft c6 is mounted a beveled gear c5, meshing into beveled gear c4 on the stubshaft c3, which latter receives its motion from the cam-shaft b5 by the gear-wheels c' and c2, as clearly illustrated in Fig. 2 of the draw- 95 ings.

In operation when the tappet b4 on one side of the loom in its downward movement depresses the tappet-lever h the latter operates the angle-lever bfi-that is to say, moves its Ioo shorter arm Z) upward. The angle-lever in turn, through the link connection d d2, throws the picker-sticks c and thus forces the shuttles over the raceway. The picker-sticks remain in the position attained (the arm ewith its shoulder e engages one end of the bridge e0) until the tappet b4 on the other side of the loom depresses its corresponding tappetlever b', which in turn operates the an gle-lever b (on t-he other side of the loom) and thus returns the picker-sticks to their former positions. At the required moment the cam e5 depresses the lever e4 and, through the cord e3, fulerumed head-lever e2, and cord e', raises the arm e upward and thus its shoulder e0 out of engagement with the bridge c".

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

l. In a loom of the character described, the combination with the frame, the main driving-shaft and the cam-shaft, of a shaft parallel with the drivin g-shaft and suitably supported in the lower portion of the frame, a series of lay-swords mounted on said shaft, a lay carried by the upper portions of said layswords, a cross-bar secured to the lower portions of said lay-swords and parallel with the lay, a series of picker-sticks pivotally secured on said cross-bar, an angle-lever at each side of the loom and also pivotally secured on said cross-bar, a series of links and straps connecting said picker-sticks and angle-levers, a bridge on each of said angle-levers, an arm provided with a shoulder and pivotally secured with one end to the lay-swords and adapted to engage with. said shoulder the bridge on its respective angle-lever, a fulcrumed head-lever on the loom-frame and above each angle-lever and having one of its ends Aconnected by a cord or Wire with the 1 with the lay and lay-swords, of a cross-bar sefree end of the arm, a cam mounted on the cam-shaft and on each side of the loom, a fulcrumed treadle-lever below each cam and adapted to be operated thereby, a cord connectin g the free end of said fulcrumed treadlehead-lever, and means for transmitting motion from the cam-shaft to each of said anglelevers, substantially as and for the purposes described.

2. In aloom of the character described, the combination with the frame, the main driving-shaft and the cam-shaft, of a shaft parallel with the driving-shaft and suitably supported in the lower portion of thev frame, a series ,of lay-swords mounted on 'said shaft, a lay carried by the upper portions of said layswords, a cross-bar secured to the lower por- 1,

Ihave hereunto set my hand this 3d day of September, 1897.
