TO ALL PERSONS T0 WHOM THESE PRESENTS SIIALL COME? I -Be it known that I, DARIUS Q. BROWN, of Lowell, in the county of Middl'esex, and State of Massachusetts, have invented anew and usefullmprovement'in the Formation or Construction of the Warp-Eyes of Wire- Heddles for Loom-Harness; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of whieh-- I Figure l denotes a wire-heddle warp-eye of the kind ordinarily made.

Figure 2 exhibits one of my improved eyes, these figures being drawnon an enlarged scale in order to more -correctlyexhibit my invention.

The eyes as heretofore made of two wires or parts AB of a'wire twisted together, as shown at "O ljand .upon a form, always, so far as I am aware, have theirextremities or ends terminating in acute angles, as shown eta a in fig. 1. It matters not whether the said former be constructed with either rounder squareedges, the termination of the eye at ach end will be by the two wires departing at an acute vangle from eachoth er. This seine. angular form of the endof' the eye renders the warp-yarn or thread liable to catch in the twistof the wires, the consequence being either injury or breakage of the warp. v

. The object of my invention is to so form the eye at each extreinityas to overcome theliability ofthe yarn being caught in or injured by the twist of the wires, nnd l'aceomplish this by subsequentlyspreading the eye lengthwise, so as to impart' to each end of it a semicircular form, or an approximation thereto, (see fig. 2,) that is, I spread the wiresg-where they form an acute angle at their'junction, so as to make their angle greater, and at the same time elongate the eye and contract the twist. This may be accomplished by aninstrument formed somewhat like a pair of pliers, or like a glove-stretcher, which, on being introduced into the eye and opened -therein, will spread the eye lengthwise. After the eye may have been so spread or treated, it will be found very difiicult,if' not impossible, for it'to catch or injure a warp-thread or a knot thereof. The spread-heddle eye is a very great improvement over the unspread one, and renders the wire-heddle even less liable than the -twine-heddle to injure or chafe the-warp. I p I v I ant-aware that twisted and other heddle-eyes have been made, in which but little or no angularity exists =at the ends of the eyes. This I do not claim.

I claim my improved heddle-eye, made substantially as described, that is, of wires or parts of a wire'twisted together, and subsequently spread laterally at theangle or-.angles of junction, in manner substantially as set forth, so as to tighten the twist at either orboth endsof the eye,"as-ai id f'or the purpose ashereinbefore eirplained. Y

J). C. BROWN.
