DARIUS G. BROWN, OF LOWELL, MASSACHUSETTS.-

IMPROVEMENT IN WIRE HEDDLES FOR LOOMS.

Specification forming part of Letters Patent No. d2,553, dated May 3, 1864.

To all whom it may concern.-

Be it known that I, DARIUS 0. BROWN, a resident of Lowell, in the county of Middle sex and State of Massachusetts, have invented an Improvement in Wire Heddlcs for Looms for Weaving Cloth; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 denotes a side view of a heddle having my invention; Fig. 2, a side view, and.

Fig. 3 an edge view, (on an enlarged scale,) of its warp-eye and the twists above and below the same.

My improvement has reference to that kind or" wire heddles whose warp eye is made by twisting two round wires together directly at and below the said eye. In Fig. 1 the two wires are exhibited at a and b, the warp'eye being represented at c as formed by twisting together the wires, as shown at d and e.

In car ying out my invention these wires, after having beentwisted together, are not only flattened in their twists :in the plane of the flat sides of the eye, but they are also to be subsequently flattened or compressed together on the opposite edges of the twists, my invention being an improvement on that for which Letters Patent No. 10,623 were granted on March 7, 1854, to Thomas Glegg and Nathaniel Stevens, as assignees of the said Olegg, by whom the invention so patented was made. The said Uleggs invention was a loom-harness metallic eye, made of round wires twisted together and compressed and flattened in their twists at the extremities of the warp thread opening or e e, the object of the flattening of the wires being to prevent the eye from catching the warpthread (going through it) in the, twist or twistings of the wires. I he said Cleggs flattening of the twists was only in parallelism with or continuation of the planes of the flat This compression of the twists causes a lateral expansion and opening of the coils, which renders them likely tointerf'ere with or take up the warp-threads which may run alongside of and next to the eye. While the flattening of the twists in continuation of theflat side of the eye so closes together the twists at the two extremities of the eye as to prevent the eye from catching in or on a warp-thread while in such eye, the difliculty of catching up or interfering with the other or next adjacent warp remains.

The object of my invention is to avoid this difficulty last mentioned, and to do so I further condense the twists, so as to remove the expansion and opening of the coils caused by the first flattening of them-that is to say. after the twists have been flattened as above described, I compress them ator about at right angles with the plane of the flat side of the eye, accomplishing this by jaws or other suitable means, the same being in manner as shown in Fig. 4, which is a transverse section of the twist, of which a and 1) denote the flattened sides, and c and d the flattened or condensed edges. I prefer, however, in the second condensation to round the edges of the twist ratherthan to flatten them, as when they are flattened they present with the side flattenings anguar edges 0 e, likely to wear or fray the warps. Fig. 5 is a transverse section of one of the twists as flattened and condensed externally, and having rounded edges in aceordante with my invention.

I do not claim a loomharness or heddle metallic eye made of round wire twisted together and compressed and flattened on two opposite sides only of each of the twists of the warpeye, and so as to prevent a thread while in the eye from being caught by the upper or lower part of the eye; but

What I do claim as my invention is- My improved loom-harness or heddle metallic eye, as made of two round wires twisted together and condensed in their twists not only in the continuations of the planes of the sides of the eyes, but in directions in other respects, substantially as set forth.
