HEDDLE FOR CROSS-WEAVING.

SPECIFICATION forming part of Letters Patent No. 613,615, dated November 1, 1898.

Application filed February 1, 1897. Serial No. 621,375. (No model.)

To all whom it may concern:

Be it known that I, RICHARD WHARroN, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Loom-Harness, of which the following is a specification.

My invention relates to loom-harness and it consists of certain improvements, which are fully set forth in the following specification and are shown in the accompanying drawings.

I More particularly, my invention relates to loom-harness designed for cross-Weaving, and especially to the heddles or devices for effecting the crossing of the warp-threads.

In carrying out my invention I employ a heddle strip or member combined with a doupneedle which controls one or more doupthreads so constructed and operated that during the formation of the sheds the doupneedle warps and free warps are crossed. These devices are so operated that the doupneedle thread is first lifted on one side of the free-warp thread and then upon the other side, and to effect this result without shifting the heddles laterally I so construct the heddle strip or member with a thread guide or guides that while it will permit the doupneedle thread and the doup-needle to pass outside of the free-warp thread when it is lifted independently of the heddle-strip it will force that thread over the donp-needle and doup-needle warp when the heddle member is lifted.

My invention also relates to certain improvements in the construction of the heddle members and of the doup-needles and in the combination of the two into doup-needle heddle members and the formation of heddles thereof. I

Myimprovements will be better understood by a reference to the accompanying drawings.

Figure 1 is a front View of a (loop-heddle strip or member embodying my invention. Fig. 2 is a side view of the same. Fig. 3 is a modification of the doup-needle. Figs. 4 and 5 are respectively a front and side view of doup-heddle strip or member, illustrating a modification of my invention. Fig. 6 is a Vertical sectional view of part of the same on the line a: m of Fig. 4. Figs. 7 and 8 are respectively a front and side view of a doup-heddle strip or member, illustrating another modification of my invention. Fig. 9 is a perspective View of a part of the heddle strip or member illustrated in Figs. 7 and 8, and Figs. 10, 11, and 12 are diagrams illustrating the operation of the doup-heddle strips in crossing the warps.

A is the heddle strip or member, which may be composed, as shown in Figs. 1 to 6, of a thin continuous strip of metal or, as shown in Figs. 7, 8, and 9, of a longitudinally-slotted strip or of wire.

B is the doup-needle, which is supported by the heddle strip or member A and guided upon it. The doup-needle extends up to about the middle of the heddle-strip A and is provided on its end with an eye I), through which the warp-thread passes. In my preferred construction the doup-needle consists of a round needle guided in a longitudinal socket a on the heddle-strip formed by bending the metal of which the strip is composed. The heddle-strip A, immediately above the eye of the doup-needle when in its lowest position, is provided with a projection, guide, or extension 0. This projection, guide, or extension may be constructed in any convenient way. The simplest, and therefore the preferable, mode of construction is to swage up the sides of the metal strip A on each side immediately above the eye of the needle, so as to form two projecting wings or extensions, as shown in Figs. 1, 2, 4:, 5, and 6, between which the doup-need'le moves when it rises and falls. These guides c serve to guide the warp-thread which is not operated by the doup-needle over the needle and doup-needle thread when the heddle-strip A is lifted. Thisoperation will be readily understood from Figs. 10, 11,

and 12, in which 8 and t are respectively the free warp and doup-needle warp. hat I here call the free warp is merely the free warp so far as this particular heddle member is concerned. That warp may be the doupneedle warp of another heddle, just as the doup-needle warp of this particular heddle may be the free warp of another heddle.

When the heddle and doup-needle are at rest, as in Fig. 10, the free warp 8 lies above the eye 1) of the doup-needle. When now the doup-needle thread is lifted, (which is accomplished by suitable heddles or lifting-wires,

not shown,) the needle B is lifted also and passes above and outside of the free warp s, as shown in Fig. 11. To permit the doupneedle to pass outside of the warp s, the heddle strip or member is preferably bent back slightly above the guides c, as at 6, so that the warp s will lie inside of the line of movement of doup-needle. \Vhen the warpif is released, the doup-needle falls back into its former position, carrying the warp t with it. Devices may be employed to positively return the (loop-needles; but I prefer to operate them by gravity. When now the heddle strip or member A is lifted, the doup-needle and warp t are lifted also and pass above the free warp s; but as the heddle-strip rises the guides c, acting on the warp 3, push it outward outside of the needle B, which passes behind the thread 15, so that the thread 8 is crossed outside of the thread i, as shown in Fig. 12.

The doup-needle may be provided with a longitudinal slot 1), forming an elongated eye adapted to receive two or more doup-needle threads which may be successively operated, thus producing variations in the cross-weaving.

In the modification shown in Figs. 4C, 5, and 6 the doup-needle passes through a slot d in the body of the strip A, adjacent to the guides c, and is provided at its lower end with clips f, which embrace the edges of the strip A. A stop g on the strip limits the descent of the needle 13. By cutting away the edges of the strip A, as at h h, means are provided for readily detaching the needle B from the heddle-strip. By raising the needle until the clips f are adjacent to the notches h the needle end may be disengaged from the strip and removed from the heddle.

In the modification shown in Figs. 7, 8, and 9 the heddle-strip is longitudinally slotted, and the needle 13 passes through a slotted cross-bar t' at about the center and is provided on its end with a foot j, guided in the slot in the heddle-strip. In this construction the metal strip immediately adjacent to the crossbar 1' is slit, as at 70, on each side, and the guides c are formed by bending forward the outer strips of metal l, the inner strips on being bent backward to throw the guide-slot in the cross-bar inside of the guide 0.

While I prefer the constructions shown, it is apparent that the heddle-strips and doupneedles may be varied in many ways without departing from the invention so far as it relates to the employment of the guides c adjacent to the eye of the doup-needle to throw the free warp forward and cross it over the doup-needle warp when the heddle-strips are operated.

While I have shown single detached heddle strips, it is understood that a series thereof may be combined with the usual lathes or frames to form heddles, or they may be operated separately by jacquard mechanism, as is well understood in the art.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. A doup-heddle strip or member, consisting of a heddle strip or piece, a doup-needle guided thereon, and a guide projection on the heddle strip or piece located adjacent to and above the eye of the doup-needle when in its lowered position, substantially as and for the purpose described.

2. A dou-p-h'eddle strip or member, consisting of a heddle strip or piece, having a portion thereof swaged or bent outward to form a guide projection, and a doup-needle guided on the heddle-strip and having its eye adjacent to and below the guide projection when in its lowered position.

3. A doup-heddle strip or member, consisting of a metal strip and a doup-needle guided thereon, the sides of the metal strip being swaged or bent forward on each side adjacent to and above the eye of the doup-needle when in its lowered position to form the projecting guide-wings 0, c.

4. Aheddle-stri p, consisting of a longitudinal piece bent as at e and provided with the projecting wings a, 0 adjacent to said bent portion.

5. A heddle-stri p, consisting of a longitudinal piece bent as at e and provided with the projecting wings a, c in combination with a doup-needle guided on the metal strip and having its eye when in lowered position located adjacent to and below the projecting wings a, c.

6. A doup-needle-heddle strip, consisting of a heddle strip or member and a doup-needle guided thereon and provided with an elongated eye Z), the heddle-strip being provided with guide projections 0 adjacent to and above the eye of the doup-needle when in lowered position.

7. The heddle strip or member, consisting of a flat piece of metal bent at its lower portion to form a longitudinal socket aand having its edges at a portion of its length above the socket swaged or bent forward to form projecting wings or guide extensions 0, 0.

8. The heddle strip or member, consisting of a fiat piece of metal bent at its lower portion to form a longitudinal socket aandhaving its edges at a portion of its length above the socket swaged or bent forward to form projecting wings or guide extensions 0, c, in combination with a doup-needle loosely supported in the socket a and having its eye adjacent to and below the projecting wings a, c.

In testimony of which invention I have hereunto set my hand.

RICHARD VVHARTON.
