PENNSYLVANIA, COMPOSING FIRM OF DORNAN WARP-CROSSING MECHANISM FOR Looms;

SPECIFICATION forming part of Letters Patent No. 761,416, dated. May 31, 1904. Application filed June 13, 1903. Serial No. 161,396. (N0, model.)

To all whom, it Harry concern.-

' Be it known that I, NATHANIEL MARoUs SHINN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Warp- Grossing Mechanism for Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to looms, and more particularly to mechanism for crossing or laterally deflecting the warp-threads.

The object. of myinvention is simplicity of construction and effectiveness of operation and the production of a stationary device that automatically accomplishes the crossing of the. pile warp-threads. over stationary pilewires to form pile. a I} According to my invention a stationary reed is provided in addition to the lay and I of'the stationary reed, this stationary reed effecting the guiding and positive control of the warp-crossing mechanism.

therein and coact therewith to effect the crossing of the threads.

I will now describe the construction of a pile-fabric loom embodying my invention, as

illustrated in the accompanying drawings, and will thereafter point out the same in claims. I Figure 1 is a longitudinal vertical section showing the principal operative parts'of the loom. Fig. 2 is an enlarged broken side elevation in partial section.- Fig. 3 is a rear view of the stationary reed, and Fig. 4 isa trolled by a figuring-harness comprising cords 7, 8, 9, 10, and 11, which are actuated by suitable jacquard or other mechanism. The binder-warps. f and g and a stuflier-warp h are controlled by heddles 12, 13, and 14:, re-

. spectively.

The lay v1 islcarriedon swords2 on a rockshaft 5 and is actuated through connectingarms 4: by cranks 3 on the main shaft 6. The

movable reed 15 may be of any suitable construction. The stationary pile-wires 16 are clamped at their front ends upon a cross-bar 17 and extend rearwardly so as to enter the dents 18 of the stationary reed 19, which is of any convenient construction. The stationary pile-wires have attached thereto attheir rearends laterally-deflected surfaces or "camswhich enter and resiliently close the dentsof the stationary reed andpositively guide the warp-threads lifted to form the pile so that they pass upward on one side of the stationary pile-wires between the upper-deflected cam and the reed and-downward on the other side thereof between the lowerdeflected cam and the reed and are thus laterally deflected and looped or crossed over the stationary pile-wires automatically between To further assist in the pile-forming operation; the rearward position of the stationary pile-wires is inclined upward to gradually approach the deflecting or cam faces of'the crossing device, therebyforming an additional guide for the looped pile-thread. Furthermore, by this construction the stationary pile-wires are at all times removed from possible contact with the shuttle.

In Fig. 1 the lay is shownin extreme forward position and the figuring warp-thread e lifted to form pile and ready for a downward movement of the jacquard mechanism or harness when the pile-thread will be crossed from right to left.

Fig. 2 represents the position of the threads after the pile-loop has been formed. The for- Ward end of the stationary pile-wires is inclined and is provided with apile-cutting edge.

It is obvious that any of the figuring-threads may be lifted to form pile and that the figuring-threads may be controlled by any suitable means and that various modifications may be made in the details of construction within the spiritand scope of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a loom, the combination with a lay and means for raising and lowering the warpthreads and forming the sheds, of a stationary reed and warp-crossing mechanism entering the dents of. the stationary reed.

2. In a loom, the combination, with a lay and means for raising and lowering the warpthreads, of a stationary reed and laterally-deflected guide-surfaces entering the dents of the stationary reed.
