WEFT-REPLENISHING MECHANISM.

Specification of Letters Patent. Patented June 17, 1919.

Application filed December 14, 1917. Serial No. 207,053.

To all whom it may concern:

Be it known that I, EPPA H. RYoN, a citipartments from which weft carriers are se-' lectively released and move downward to transfer position. Such magazines, as heretofore made, have included a weft carrier support which holds the selected weft carrier yieldingly in the path of a transferrer by which it is thereafter inserted in the indicated shuttle. If for any reason, such as a misplaced shuttle, the weft carrier is not transferred to the shuttle, it is then necessary to remove the untransferred weft carnor from the magazine, as the next indication may call for a weft carrier of a different color. Accordingly means has also been heretofore provided for immediately releasing any weft carrier which fails of transfer, such means being preferably associated with the shuttle feeler and releasing the weft car= rier upon the resetting of the feeler.

It has been found, however, that a weft carrier is occasionally left in a partially inserted position on the shuttle. When the shuttle moves backward witha weft carrier partially inserted the-weft carrier engagesthe end of the weft carrier support with disastrous results. a

It is the principal ob ect of my invention to provide a construction by which injury to the weft carrier and support may be avoided under; the circumstances above noted.

With this object in view, 'an important. feature of my invention consists in the pro vision of devlcespennitting' the weft carrier support to move rearward. beyond its normal inoperative position upon engagement by a misplaced weft carrier.

In the preferred form of my invention provision is'also made for moving the free end of the support upwardly as the support is forced rearward, thereby clearing the misplaced weft carrier. A further feature of my invention relates to the provision of improved devices for controlling the movement of the weft carrier supportto its operative and inoperative positions.

My invention further relates to certain arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings, in which Figure l is a sectional side elevation of a portion of a magazine with my improved Weft carrier support mounted thereon;

Fig. 2 is a detail view similar to Fig. 1, but showing certain of the parts in a different position, and

Fig. 3 is a sectional plan view taken along the line 33 in Fig. 2.

Referring to the drawings, 1 have shown a lay 10, a breast beam 11, a two-color magazine frame 12 mounted onthe breast beam 11, and a transferrer 13 of the usual form pivoted at 14 to the magazine frame 12.

All of these parts are or may be of the usual construction, and form no part of my invention.

As a weft carrier W is released from one of the magazine compartments 12, upon indication of transfer, it descends to the position indicated in Fig. 1, in which position it is yieldingly retained by a stop 15 and a Weft carrier support 16. The support 16 is pivoted at '17 to the swinging end of an arm 18 mounted upon a stud- 19 fixed in the frame 12. A coilspring 20 (Fig. 3) encircles the stud 19 and is connected at one end tothe hub of the arm 18 and at its opposite end to a collar 21 adjustably secured to the stud 19. The spring 20 normally swings the arm 18 to the le t in Fig. 1, such movement being limited by a stop screw 22 threaded in a lateral projection 23 of the arm 18.

The support 16 is extended rearwardly beyond the arm 18, the rearward extension being connected by a spring 24: to a lug 25 on the arm 18. The support 16 preferably extends through a slot in the arm'18 and ward by the spring 24, thus determining the normal relative position of the support 16 on the arm 18.

The magazine 12 is provided with the usual shuttle feeler 26 which is moved from the position shown in Fig. 2 to that shown in Fig. 1 prior to w'eft carrier transfer. The shuttle feeler 26 is loosely mounted upon a stud or short shaft 27 and is provided with an arm 28 having a stud 29 secured in the outer end thereof. The stud 29 extends laterally to a position in which it engages a cam surface 30 on the outer end of the arm 18. \Vhen the shuttle feeler 26 is innormal or raised position the stud 29 forces the arm 18 to the right (Fig. 2) thus withdrawing the support 16 from operative position. When the shuttle feeler is depressed upon indication oftransfer,.the arm 18 is released by the stud 29 and is then free to swing to the left under the influence of the spring 20, thus advancing the support 16 to operative position as shown in Fig. 1. These movements constitute the normal operation of the device.

As previously mentioned, however, it sometimes happens that a weft carrier will be left in the shuttle in a partially inserted position as indicated at a weft carrier will be carried rearwardly with the'shuttle and will engage the end of the weft carrier support 16. As this support, in my improved construction, is mounted upon the swinging arm 18, the support is movable bodily rearwardly to partially avoid injury.

Such movement is necessarily limited, however, and accordingly I have further provided means for disengaging the support 16 from the weft carrier W as the support and carrier move rearwardly. For this purpose a cam surface 31 is formed upon the lower edge of the support .16 which cam surface engages the stud 29 as the support is forced rearwardly by the misplaced weft carrier. The joint action of the stud 29 and cam surface 31 lifts the support 16 out of the path of the weft carrier W as theisupport is forced rearwardly. The support is thus released and all injury thereto is avoided.

Having thus described my invention, it will be evident that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims,

W in Fig. 2. Such support, an arm to which said support is pivoted, said arm being mounted upon a fixed pivot, means to adjust the operative position of said arm, and means to move said arm and support to inoperative position after transfer and thereby release any weft carrier which remains supported in delivery position by said weft carrier support.

In a loom, a magazine, a weft carrier support, means to move said support to operative posit-ion, means to move said support to inoperative position, said support being also movable rearwardly to abnormal position by engagement with a misplaced weft carrier, and means to raise said support above normal inoperative position when thus forced rearwardly bv such engagement.

3. In a loom, a magazine, aweft carrier support, a swinging arm on said magazine to which said support is pivoted, a spring to yieldingly position said arm relative to the magazine, and a second spring to yieldingly position said support on said arm.

4. In a loom, a magazine, a weft carrier support, a swinging arm to which said sup port is pivoted, a nection through which said shuttle feeler determines the position of said arm and said support.

5. In a loom, a magazine, a bodily movable weft carrier support having a cam surface, and a member engaging said cam surface and effective to raise the free end of said support when'said support is forced rearwardly beyond its usual inoperative position.

6. In a loom, a magazine, a weft carrier support, a swinging arm to which said support is pivoted, a cam surface on said arm, a shuttle feeler, and a stud on said shuttle feeler engaging said cam surface to position said arm and support.

7. In a loom, a magazine, a weft carrier support'having a cam surface, an arm to which said support is pivoted also having a cam surface, a shuttle feeler, and a stud on said shuttle feeler having operative relation with both of said cam surfaces.

In testimony whereof I have hereunto. af-

fixed my signature.
