Serial No. 332,640.

This invention relates to weft detectors more particularly usable on multicolor weft replenishing looms and it is the general object of the invention to provide improved means for withdrawing the detector at the time of transfer.

mounted. 'With the type of feeler more par ticularly usable in Connection with my pres ent invention there is not only no opportunity to convenientlyadd a lateral PIOJQCiZlOIl, but

the detector itself projects high enough sothat the use of the usual withdrawing means is rendered impossible. I i It is a further object of my present invention to provide the transferrer arm with an auxiliary lug positioned to engage an: up-

standing portion of weft detector carrier so that the latter may be moved forwardly at the time of transfer to withdraw the feeler. R is a more specific object of mypresent inyentioi'r to employ this auxiliary lug or finger as the means for applying the spring force which is depended upon to hold the transferrer normally raised position, the connection between the spring and the finger being suclr as not to interfere with the with-. drawing operation of the finger.

lVith these d other objects in which will appear the description prooeeds niy invent-ion resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings, wherein .a convenient embodiment of my invention is set forth, I l

Referring particularly to Figs. 1 and2 l have shown a loomside 10 on which is mounted foot 11 on the weft replenishing mechanism 12. The latter may be provided with a plurality of compartments 18 down which reserve bobbins may move toward transfer position. The weft replenishing mechanism is provided with a hub 14: through which extends a relatively large stud15 held in position by a set screw 16. The transferrer arm 17 has a hub 18 throughwhich the stud 15 extends loosely and said hub has depending therefrom the usual pair of spaced arms 19 which support astud 20 on which is pivotally mounted the usual latchholder 21. Mechanism not shown is employed at the time of transfer to lift the latch with respect to the arms 19 so that'said latch will be infthe path of the lay L to effect a downward movement of the horizontal arm 22 of the transferrer.

A collar 23 is mounted on the right hand end of the stud 15 as viewed'in Fig. 2 and supports a relatively largetorsion sprin n a b one end of which as mdicated at 25 enters a portion of the collar. A co-tter pin 26 holds the collar in fixed angular relation with respect to the stud so that the, end 25 of the torsion spring is held in fixed position.

Inorder to support the detector I may pro ride an arm 3 secured at its upperend by The torsion spring has a horizontally extending set screw 35 to one of the tie rods which is a normal part of the magazine construc tion. Said arm 2% has a horizontal foot 37 and a bolt 38 which extends through both 5 the cap and bed of the detector and also the foot 37. By means of the structure supported by tie rod 36 the detector is held in position to be engaged by the advancing bobbin I) :arrie-d by the shuttle S on each forward detecting beat of the loom.

From the matter thus far described it is understood that when the detector 83 engages a full supply of yarn the slide 32 will A, be moved forwardly substantially to the pofig sition shown in Fig. 1', but when the yarn is exhausted the detector will slide along the denuded bobbin and the slide 82 will remain It rest. It is obvious from an inspection of Fig. 1 that on transferring beats of the loom it is desirable to move the detector 33 forwardly and out of the path of both the outgoing and incoming bobbins, and it is an important object of my present invention to effect this result. In carrying my invention into effect I provide the slide 32 with an upward extension and form with the hub 18 21 depending finger ll which has a notch 42 to receive the horizontal end 27 of the torsion spring 24. The auxiliary finger ll extends downwardly below the end 27 of the spring and lies over the cap and bed as shown more particularly in Fig. 2. It will be noted that the finger a1 is shorter than the arms 19, being necessarily smaller than the latter arms in order. to be disposed above the cap and bed in position to engage the upturned end 40 of the slide At the time of transfer the transferrer arm will move downwardly from the position shown in Fig. 1 to that shown in Fig. 3, whereupon the finger sl'will be moved for wardly or to the left as viewed in Fig. 3 to engage the vertical extension IQ of the slide 32 to move the latter away from the lay. The effect of this operation is to move the detector 33 from the path of the outgoing and incoming bobbins.

From the foregoing it will be seen that I have provided avery simple means for withdrawing a weft detector of the type having a slide with an upwardly extending portion which isaccessible only by apart moving over the bed and cap of the detector. It will further beseen thatthe depending finger 4:1 is the means by which thelarge spring 241cm erts its yieldin for-ce on the transferrer arm and that said fiiger is shorter than theusual arms 19, the withdrawing mechanism set forth herein being entirely independent of the latch and tl'iepartsby whichithe'same is supported on thetransferrer arm.

Having thus described my invention it will be seen that changes and modifications ma be made-therein by those skilled inthe art without departing from tli'e spir'it and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a withdrawing device for side slip feelers, a pivoted transferrer arm having a pair of spaced legs to support a latch by means of which the transferrer may be actuated, a forwardly movable slide, a detector arm pivoted to the slide to move in a. horizo-ntal angular direction at the time of indication of weft exhaustion, guiding structure for the slide, the forward end of the slide being bent upwardly, and a finger formed on the transferrer arm lying substantially over the slide and in alignment with the bent end of the latter so that when the transferrer arm is actuated said finger will engage the bent end to move the slide forwardly.

2. In withdrawing mechanism for a side slipping weft detector, a detector support, a slide movable forwardly in said support, a detector pivoted on the slide and having an angular movement in a horizontal direction at the time of indication of weft exhaustion, a transferrer arm pivoted above the detector support and movable in a vertical plane, means by which the transferrer may be moved in a vertical plane, the forward end of the slide being bent upwardly, and a withdrawing finger rigid with the transferrer arm lying over the slide and positioned to engage the upturned end of the slide when the transferrer has a transferring movement to move said slide and pivoted detector forwardly, said finger when engaging the slide moving in a vertical plane substantially at right angles to the plane in which the detector swings when giving indication of weft exhaustion.

In testimony whereof I have hereunto affixed my signature.

OSCAR V. PAYNE.
