WEFT-THREAD CATCHER, AND HOLDER. FOR. AUTOMATIC WEFT-REPLENISHING LOOMS.

Application filed August 6,

To all whom it may concern:

Be it known that l, EUGENE H. BALLOU, of Pawtucket, in the county of Providence and State of Rhode Island, have invented anew lVeftThread Catcher and Holder for AutomaticlVeft-Replenishing Looms, of which the following is a specification.

In automatic weft replenishing looms the spare weft carriers are usually maintained in a magazine mounted on a fixed part of the loom and the end of each weft carrier isatev tached to a weft end holder. Then, when a weft carrieris supplied to the loom and the shuttle is picked from the replenishing side of the loom to the opposite side, a strand of weft is left extending from the Weft nd holder to the selvage of the cloth. It is the usualpractice to cut this strand of weft close to the selvage so that a loose end of weft is left secured at one end to the weft end holder. This loose weft end is apt to get caught by the picker and'inay get broken off and carried into the shed with a resulting blemish in the cloth. The purpose of the present invention is to provide a catcher and holder for this loose weft end which will maintain it out of the way of the picker until the weaver hasopportunity to visit the loom and remove it altogether.

The invention is illustrated in the accompanying drawings, -wherein- Figure 1, 1s a front view of so much of the replenishing end of the loom as is necessary for an understanding of the invention. Fig. 2, is a plan View of a portion of the lay and shuttlebox at the replenishing side of the loom. Fig. 3, is a vertical cross section in the plane indicated by the line 33 in Fig. 1.

Fig. 1 illustrates the lay A; the shuttle box B, at the replenishing side of the loom; the shuttle C, within the box; the picker D; a rotary niagaziiie E, of the well known Northrop type (as illustrated for example in United States Letters Patent of Northrop No. 529,940, November 27, 1894) a weft end holder F, carried by the magazine; a weft carrier G, in the magazine; and a strand of Weft H, extending from the weft end holder to the selvage of the cloth shown at I, in Fig. 2. This condition of the weft end H, exists until it is cut close to the selvage by a thread cutter of any of the now well known varieties. One such cutter is illustrated in United States Letters Patent of Draper and Stimpson No. 585,465, June Specification of Letters Patent.

bracket J, is secured to the front side of the lay and it has a forward extension K, and a top L, which is secured to the back of the lay and overhangs therace plate 'M, and

the shuttle path, being a sufficient distance above the race plate to afford room for the free passage of the shuttle. The extension K, extends forwardly of the race plate, the front of the lay and the front of the shuttle box, and constitutes a holder for the weft end. A thread catcher N, is piroted at O, to the top plate L, extends downwardly through a slot P, therein, and rests at its lower free end upon the bot-- tom of the holder K, as shown in Fi 3, thereby closing the rear of the holder. The lower end of the catcher N, is beveled as shown at'Fig. 3, so as toafford a flaring mouth or entranceQ, for the weft end. The catcher is forward of the front of the shuttle boX.

When a fresh weft carrier has been inserted in the shuttle and the shuttle has been picked to the other side of the loom the freshly laid strand of weft is beaten up to the fell of the cloth to the position shown in Fig. 2. The lay then retreats from the fell of the cloth as indicated in Fig. 2, thus leaving the weft end H, extending at an angle to the length of the lay from the fell and selvage of the cloth to the weft end holder F. During this retreat of the lay the weft end H, is guided upwardly and forwardly by the outwardly and upwardly curving guide B (Fig. 3), of the bracket J, into the flaring entrance Q, below the catcher N. This inclined thread directing guide is between. the shuttle path and the holder and guides the weft thread to the catcher and the holder. Then as the lay continues its retreat the weft end passes beneath the catcher N, and into the chamber of the holder K, which is forward of the catcher N. The weft end is sufficiently taut between the selvage and the weft end holder, and the catcher N, is sutliciently light so that the thread lifts the catcher and gets into the holder. Then,

' in a weft replenishing loom of the character set forth in Letters Patent of the United States, No. 1,244,827, Oct. 30, 1917. In accordance with that patent, when a change of weft is called theshuttle box stops during its forward movement when about half way forward while the lay continues its forward course so that the shuttle and shuttle box are standing still at the time a fresh weft carrier is transferred from the magazine into the shuttle. This involves a position of the magazine farther back than in the loom shown in the aforesaid Northrop Patent No. 529,940, wherein a fresh weft carrier is transferred from the magazine to the V shuttle when the lay and the shuttle box are substantially at their most forward positions. By reason of this rearward location of the magazine in the loom of the aforesaid Patent No. 1,244,827, the place on the weft end holder F, where the newly inserted weft end .H, is located is closely above the picker when the picker acts with the result that there is an added danger of the loose weft end being caught. WVhen, however, the thread holder and catcher herein set forth are employed the loose weft end is held sufficiently forward of the picker to prevent the weft end being caught thereby.

' I claim 1. A weft replenishing loom having, in

combination, a weft end holder carried by the lay and extending in front of the race plate of the lay and located close to the mouth of the shuttle box at the replenishing side of the loom; a pivoted gravity catcher closing the rear of the holder and resting on the bottom of the holder with a flaring entrance between it and the bottom of the holder facing the shuttle path; and an inclined weft thread directing guide between the shuttle path and the thread catcher.

2. A weft replenishing loom having, in combination, a weft end holder carried by the lay and extending in front of the race plate of the lay and located close to the mouth of the shuttle box at the replenishing side of the 100m; and a pivoted'gravity catcher closing the rear of the holder and resting on the bottom of the holder with a flaring entrance between it and the bottom of the holder facing the shuttle path.

' 3. A weftreplenishing loom having, in combination, a weft end holder carried by the lay and extending in front of the race plate of the lay and located close to the mouth of the shuttle box at the replenishing side of the loom; and a pivoted gravity catcher closing the rear of the holder and resting on the bottom of the holder.

4. A weft replenishing loom having, in combination, a weft end holder carried by the lay and extending forward of the shut-' tle box at the replenishing side of the loom, and a movable catcher normally closing the rear of the holder.

In witness whereof, I have hereunto signed my name.

EUGENE H. BALLOU.
