LOOM-HARNESS-HOLDING' DEVICE.

To all whom it may concern:

-Be it known that I, WALTER G- SHULL,

*a citizen of the United States, residing at New Brookland, in the county of Lexington and State of South Carolina, have invented certain new and useful Improvements in Loom-I'larness-Holding Devices, of which the following is-a specification.

Preliminary to-t ving in warps by means of the machines now used for that purpose, a portion of the old warp, with the reed, harnesses, and drop wires, ifany, in position thereon, is removed from the loom to the \\"arp-tying machine to be tied to the new warp. \Vhen removing the old warp from the loom a strip of cloth is cut otl' in front of the reed to prevent the ends of the warp from slipping through the reed and the har- 'nesscs, and the opposite ends of the warp dillerent positions.

threads are temporarily held in a sheet and prevented from ta-ngling 'by any suitable means, such as a common tongue clamp. When being tied,to a new warp, the section .of the old warp is supported in the Warp carriage of the warp-tying machine, said old warp being secured in said carriage by means of a. machine termed a loader. The loader comprises a support over which the old warp is stretched, and a movable support for the reed, harnesses, and drop wires.

One of the objects of the present invention is to provide. means for securing the harnesses to their support in the loader, in order thatthe warp m. y be readily stretched taut across support.

Another object of the invention is to provide means for automatically releasing the harnesses upon the. completion of the oporation of securing the old warp in the warp carriage of the warp-tying machine.

In the accompanyiug drawings, Figure 1 is anend elevation of a. a harness-holding apparatus embodying the features of my invention. Figs. 2 and 3 are similar views, but showing the parts in Fig. 4 is a top. plan view, with parts broken away, representing the mechanisms in the position they are shown-to occupy in Fig. i

'lhe loader comprises afharness carrier l3 and means including the arms C for supporting the old warpin a sheet.

a refers to the harnesses; 7), to the warp threads; and c, to a tongue clamp in which the severed ends of the warp threads are loader provided with Specification of Letters Patent. Patented Apr. 19, 1910. Application filed June 28, 1907. Serial No. 381,210.

- secured. The harnesses pins B fixed in the harness-carrier B. The loader comprises means for raising and lowering said harness-carrier.

The means for securing the harnesses in place upon the harness-carrier B comprises a bar 1 adapted to overlie said harnesses, said bar being faced with felt orsome other softmaterial 2. The bar 1 is secured to the outer ends of two arms 3 pivotally mounted upon the harness-carrier B at opposite ends of the handle 4 fixed t0 the bar 1 near its middle. provides means for manually operating A stop arm 5 is fixed to each of the arms 3 in position to strike against the under side of the harness-carrierB when the parts are in the position indicated in Fig. 1. i

For moving the bar 1 into and out of engagement with the harness a, I provide means comprising, in this instance, two levers 6 pivotally mounted at their lower ends in bearings 7 secured to the -.fioor or any other suitable support, said bars being connected to move together by means of a crossrod 8. A tre'adle 9 is mounted in position to be conveniently reached by the operator when standing at the forward side of the loader, said treadle being connected with the levers 6 by means of a link 10 pivotally connected with said treadle and the cross-bar 8. In the upper portions of each of the levers 6 is formed a notch 11 adapted to receive the bar 1, said notch having a square shoulder or end wall 12. Above the notch 11- is mounted a hook 13 arranged to have a limited pivotal movement with reference to said lever. Springs 14 connected'at one end to the levers 6 and at their opposite end to a suitable fixed point, tend to move said levers into the position indicated in Fig. 1.

Assuming the parts to be in the position shown in Fig. 1, the operation is as follows: The harnesses are suspended uponthe pins B and the warp threads laid over the supporting means provided for them" in the loader. The operator then depresses the treadle 9, pulling and carrying the hooks 13 into engagement with the ends of the bar 1. Said bar is thereby thrown over upon the harnesses a,' in which position it remains by gravity. The springs 14: tend to hold the levers 6 against the ends of the bar 1, as shown in a are hung upon latter, said arms being preferably curved, as shown, and formed of spring material. A

Fi 2. The warp threads may now be u ed taut, the bar 1 holding the harnesses rmly in place. The loader A is then operated to secure the old warp Z) in the carriage (not shown) of the warp-tying machine,

during which operation the harness-carrier B is raised into the position indicated in Fig. 3. The springs 14: hold the levers 6 in contact with the bar 1 as the latter rises, said bar entering the notch 11 when the harnesscarrier reaches its most elevated position.

In the completion of the loading operation,

the harness-carrier B is lowered into its initial position. In its descent the harness carrier B carries the bar 1 into engagement with the shoulders 12 upon the levers 6, and is thereby prevented from descending farther.

The harness-carrier B continuing to descend,

the arms 3 are tilted until the point is reached where the springs 14 are enabled to throw the bar 1 rearwardly out of engagement with the harness, as shown in Fig. 1.

The warp carriage, with the old warp, harnesses, reed, etc, secured thereto, is now removed from the loader.

It is evident that various changes may be made in the embodiment herein shown without departing from the spirit and scope of my invention, therefore no undue limitation should be understood from the foregoing detailed description.
