WEFT-REPLENISHING MECHANISM.

Speoincation of Letters Patent.

Patented Apr. 2, 1918.

but have been commonl of a type in whchi-.

on every alternate p the support is actnate the lay. Such actuation is objecbeat of V tionable as the operation is entirel without useful function except after themdication .f a. transfer. The parts are thus subject to much needless wear with no correspondintadvantages.

is the objectvof my present invention provide a weft carrier `support which to mams in inoperative position until a transfer is indicated and returns to inoperative vposition immediately after its functionhas been performed.

In the embodiment of my invention herein disclosed the weft carrier support is lassociated with the shuttle feeler and is moved to operative and inoperative positions substantially simultaneously with said Ifeeler.

With this general object in view, my invention relates to-certain arrangements and -combinations of parts'hereinafter disclosedy and more articularly pointed out in `the appended c aims. p

A preferred form of my invention is shown in the drawings, in which Figure 1 is a right-hand side elevation of one end of a weft replenishing magazine with my improved weft carrier support embodied therein- Fig. 2 is a detail side elevation showing certain of the parts of Fig. 1 in a different position, and

Fig. 3 is a sectional plan view taken along the line 3 3 in Fig. 2. Referrin to the drawings, I have shown a portion o an end frame 10 of a two-color magazine of the stationary type. The ma azine is provided with guide ways 11 and 2 forA weft carriers of different colors, and suitable mechanism (not shown is provided for releasing a weft carrier o the desired color upon the indication of transfer, said carrier then moving to the position of the carrier W in Fig. 1. A. transferrer 13 of the usual4 type 1s provided for thereafter transferring the weft carrier W to the exhausted shuttle. ofthe parts thus far described may be of the usual type and form no part of my invention.

. It is necessary to support the weft carrier in the position indicated at W in Fig. 1 until the'descent of the transferrer 1B by which the weft carrierfi forced into the exhausted shuttle. It sometimes hap ens however that the shuttle will be mis a in the shuttle box to an extent which renders a successful transfer impossible. In this .event the transfer is revoked and it is n that the w'feft. carrier W be--released and removed sc 'that the magazine will be in condition to perform the next indicated transfer',which 'may of a difof t e support 144;l and -at the opposite end to a collar 17 angularly ladjus'ta le on the stud'15.'/l`he s rm Y 1G-"acts to force the upportl yiel ing yinto' operative posiion. Y The support 14 is provided with a rearwardlyz extending arm 18 overl ing a stud 19 on an erm20 secured toarock s aft 21. The shaft 21 is rotatable in fixed bearings in the frame 10 and has secured thereto' a shuttle feeler 22 and an arm 23 connected by a link 24 to control mechanism not shown. Said control mechanism is,1ho'wever,` fully shown and described in the prior patent to Ryon No. 972,722, issued October 11, 1910, and it need stated merely that the link 24 is secured to an arm mounted upon a shaft corrsponding to the shaft 38 of the Ryon patent, the parte being so connected that the link 24 will be raised to the position shown in Fig. 2, when the parte of the con trol mechanism are in the inoperative osition shown in Fi 7 of the patent. urthermore, the par are yieldingly retained port, -w ich moves to the inoperative posimoves to the position indicated at N and is normally transferred immediately therefrom to the exhausted shuttle.

As the lay 26 completes its forward stroke' the box plate engages the shuttle feeler 22, returning the same to the inoperative position shown in Fig. 2, in which position it is yieldingly retained by the control mech anism above described. As the shuttle feeler moves upward the stud 19y on the arm 20 l is also moved upward, thus raising the rear- `vvard'eiitension 18 of the support lftand depressin the operative portion of the suption shown in Fig. 2 and releases the weft carrier W if said carrier still remains in the magazine. u The parts are thus restoredto their original inoperative position in which they remam until a transfer is again indicated and the link 24 is again actuated to depress the feeler 22 and Apermit upward movement of the support l to operative position. 'lhe parts thus remain at rest during the entire .operation of the loom except for the occasional eriods of transfer.

Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departingfrom the spirit and scope of my invention as set forth in the claims, and I do not wish to be limited to the details herein disclosed, but what I claim is l. In a loom, a magazine, a weft carrier support maintained in ino erative position during the normal operation of the loom, means to move said support to operative position, when a weft carrier transfer is indicated, and means to thereafter return said support to inoperative position.

2. In a loom, a magazine, a weft carrier support maintained in inoperative position during the normal operation of the loom and rendered effective after a transfer indication to hold a weft carrier in said magazine in transfer position, and means to withdraw said support to release a weft carrier which fails of transfer.

3. In a loom, a magazine, a weft carrier support maintained in inoperative position during the normal operatlon ofV the loom, yielding means eii'ectlve to move said support to operative position upon indication of transfer1 and means to positively withdraw said support from operative position after the completion of the transfer operation.

4. In a loom, a magazine, a normally inoperative weft carrier support, a normally inoperative shuttle feeler, means to give said e'eler and said support substantially simultaneous movements to operative position upon an indication of transfer, and connections between said feelerand said support whereby said feeler is effective to return said support to inoperative position.

5,. In a loom, a magazine, a normally inoperative weft carrier support; a shuttle feeler, and connectionsI between said feeler and said support whereby movement of said feeler to operative position permits said support to move to operative position.

In testimony whereof I have hereunto affixed my signature. v

ARTHUR LAUZON.
