HEDDLE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 363,002, dated May 17, 1887.

Application filed September 29, 1886. Serial No. 214,855. (No model.)

To all whom, it nmy concern.-

Be it known that l, CALEB K. SAWYER, of Clinton, in the county of \Vorccster, State of Massachusetts, have invented a certain new and useful Improvement in Heddles for Looms, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation representing a heddle embodying my improvement, the eye of the heddle being provided with one wheel; Fig. 2, a front elevation of the same; Fig. 3, a side elevation representing a heddle embodying my improvement, the eye of the hcddle being provided with two wheels; Fig. 4, a side elevation of the same, and Fig. 5 an elevation showing the construction of an ordinary heddle.

Likeletters of reference indicate corresponding parts in the different figures of the drawmgs.

It is well known that ordinary beddlcs, more especially those employed in weaving wirecloth, are rapidly worn out and destroyed by the friction of the warp-wires; also, that when a warp-wire breaks and is mended the splice or knot is liable to wedge or catch in theeye of the heddle in its passage through the same, thereby breaking the hcddle and causing delay in the work.

My invention is designed to obviate these objections, and to that end I make use of means which will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the upper, and B the lower, section of theheddle,eaeh of said sections being preferably composed of wire and provided at the inner end with a loop, at, for connecting it with the sheave-block, and at the outer end with a loop, m, through which the rail of the harness-framepasses. The sections are respectively represented as composed of a single wire which is folded upon itself, its members being twisted together at f to form the loop at, and at b d to form the loop m, the body of each section being double or composed of two strands, as shown at t. The body of the section may, however, consist of a single strand, if preferred.

Between the sections A B a block, 0, carrying a sheave or peripherally-grooved wheel, D, is introduced, said block being connected to said sections, as shown at 2.

In Figs. 1 and 2 the block is represented as provided with but one sheave or wheel; but I sometimes employ two, as shown in Figs. 3 and 4, especially for coarse warps, the wheels being preferably-of smaller diameter when two are employed than when but one is used. The sheave isjournaled on an axle, c, in the body 0, and the groove Z in its periphery is of such depth as to prevent the wire from coming into contact with said body. \Vhen but one sheave is used,as shown in Fig. 1, a turn is taken in the warp-wire, or the wire is carried once around the sheave, in order to keep itproperly in the groove; but when two sheaves are employed, as shown in Figs. 3 and 4, the wire is simply passed between the sheaves, no turn being taken around either.

It will be obvious that the block and its sheave or sheaves, as the case may be, when considered as awholc, constitute the eye of the heddle.

Having thus explained my invention, what I claim is- A loom-harness heddle comprising two sections, each of said sections being composed of wire provided with loops at its opposite ends and with twists adjacent to said loops, a pulley-block provided with eyes engaged by the inner loops of said sections, and a pulley pivoted in said pulleyblock, substantially as de scribed.

CALEB K. SAWYER.
