'As indicated in the shed.

end controller constituted as a part-er and The lay 5 may be operated as usual from clamp Which on call for replenishment is thecrank shaft'and at its outer endcarries moved rearwardly towards the shuttle box I the replenishing shuttle box 6, and the shuttle to position the parter and clamp for parting 7 may be of usual type of filling replenishing and clamping the filling end close to the shuttles nowwell-known in the art.,

The front shuttle box plate is provided which divides the front box plate into the anchoring member 9 and the shorter upper member 10 which is secured to the anchoring member 9 at the outer portion thereof, as at 11, and is solely supported by the anchoring member.

The lower flange portion of the anchoring member may be secured to the lay by

bolts

12 and 13 which extend through slotted lugs 14 formed in the flange of the anchoring member, with the result that while the anchoring member is rigidly secured in position, the shorter upper member 10, being supported solely at the outer portion of the anchoring member, may yield to some degree, and as the shuttle enters the replenishing shuttle box the inner face portion of the an choring member will first engage the shuttle and resist the first impact, and thereafter the shorter upper member will act upon the shuttle as it moves to picking position in the shuttle box.

Between the inner end of the anchoring member and the inner end of the shorter upper member of the front box plate there is a free and unobstructed opening which not only provides an open inner end for the front box plate but likewise presents a space into which the spent filling end may be thrown as the shuttle comes to rest.

At the inner end of the anchoring member 9 is a projection constituting a spent end catcher 15 which extends frontwardly and below the level of the lay end A notch or hook is formed at the top portion of the projection tov catch the incoming filling end should it tend to slide by the top of the box plate into the shuttle box.

When the spent filling end is withdrawn from the shuttle box, as hereinafter descirbed, it is held in front position for several picks or until the temple thread cutter parts it at the selvage, but should the spent filling end be broken by catching on some of the lay parts before it is cut at the cloth selvage, the loose end would probably be drawn into the shed. The thread catcher of the present invention, however, avoids this objection by holding the spent filling end, which is given a. certain amount of slack between the 'cloth selvage and the thread parter and clamp, as will appear, so that it is prevented from catching on any part of the lay or shuttle box during lay movements.

Secured to the hopper or magazine stand is a stud shaft 16 on which is mounted the transferrer 17 normally under the influence of a spring 18, as usual, for maintaining the transferrer in its upper or inoperative position.

Extending downwardly from the hub of the transferrer is an arm 19 to which is pivotally connected at 20 the usual dog 21, and ex tending from the dog 21 is a stud 22 which engages the slotted arm 23 mounted for pivotal movement about the axis 24: on call forreplenishment of filling, the result being that on rocking movement of the shaft 24: the dog 21 will be raised into the path of the usual bunter 25 on the lay, whereby the transferrer is operated to transfer a fresh filling carrier to the shuttle and eject the spent filling carrier or bobbin therein.

Mounted on the transferrer stud 16 at the outer end portion thereof is a bracket, the hub portion 26 of which is secured to the stud shaft 16, and extending downwardly from the hub are the arms 27 and 28 which are arranged in a vertical plane inclined rearwardly towards the outer end of the shuttle in the replenishing box.

The arms 27 and 28, being positioned as described, carry the guide 29 for a slide 30 which has a movement towards and from the front of the loom in an inclined path diverging outgvardly towards the outer end of the shuttle The inclined slide 30 has a laterally projecting portion 31, Fig. 3, and upon which is mounted the thread controller constituted as a thread parter and clamp having the usual cutting and clamping members. The fixed cutting member is indicated at 32 and the fixed clamping member at 33, while between the two is the movable cutting member 3 1 and the movable clamping member 35, which are pivoted to the projecting lug 31 as at 36, and a pin 37 connected to the movable cutting "and parting members serves to actuate them as will more fully appear.

Mounted upon the transferrer stud 16 for rocking movement is the yoke 38 having the

arms

39 and 40 which swing about the transferrer stud. The arm 10 is extended downwardly and is provided with a slot 41 at its lower end portion which engages arelat-ively long pin 42 extending laterally from the slide 30, as indicated more clearly in Fig. 3. The

arm 40 which constitutes an actuator for the slide moves or swings in a vertical plane (:1 tending at right angles to the lay, while the slide 30 which is actuated by the arm 40 moves from front to rear position in an inclined path to part and clamp the filling, and as the actuator swings frontwardly in the vertical plane of its movement the slide 30 moves frontwardly 1n an 1ncl1ned direction towards the cloth selvage or inner end of the shuttle box, with the result that on call for replenishment of filling, as will later appear, the actuator and the thread parter and clamp will cause the spent filling end to be withdrawn frontwardly from the shuttle box to provide slack between the parter and clamp and the cloth selvage so that the slack spent filling end may engage beneath the thread catcher 15 as the lay again moves frontwardly and thereafter the filling end will be prevented arm 23, and since the shaft 24 is rocked on call for-replenishment of filling theactuator 40 will be moved rearwardly to position the thread parter and clamp'to part and clamp the thread adjacent the shuttle eye, and when the shaft 24; rocks in the opposite direction after replenishment, the actuator'will again be moved frontwardly in its plane of movement to withdraw the slide 30 and the thread parter and clamp frontwardly in an inclined path towards the inner end of the shuttle box.

Should the spent filling end be unprovided with slack as it is drawn frontwardly from.

the shuttle box it is liable to catch upon the upper portion of the anchoring member 9 of the front box plate or upon the stud 13 which secures the anchoring member to the lay, but

by providing slack in the spent filling end as it is withdrawn from the shuttle in the inclined path described, the spent filling end will engage beneath the catcher 15 and be thereafter held from moving into the path of the shuttle or the air currents produced thereby. p

Mounted upon the transferrer stud 16 is a second yoke 47 mounted for-rocking movement, and extending towards the inner end of the shuttle box is the arm 48 secured to.

the yoke and likewise connected by a yielding member 49 to a stud 50 on the downwardly extending arm 19 of the transferrer. Connected to the outer end of the yoke .47 is an arm 51 in which is adjustably'mounted a parter and clamp closing member 52 which,

when the parter and clamp are in rearward position, 7 V and clamp to part andclamp the spent acts upon the pin 37 ofthe parter It is .desirable'that the clamped end of the spent filling be held by the parter and clamp until the next call for replenishment offilling, and in order to open the parter and clamp as they move to rear positionas described, there is a tr p opener 53 of usual construction and supported for rocking movement freely in one direction to act upon the pm 37 and cause separation of the parter and clamping members as they move to rearward position.

As the parter and clamp move to rearward position to part and clamp the spent filling end, it is desirable that they should be properly positioned in the enlarged opening 54 in the front box plate, and to this end the slide 80, which as above described, moves in an inclined direction rearwardly. towards the outer end of the shuttle box and then frontwardly towards the cloth selvage or inner end of the shuttle box, is provided with a hunter 55 which may engage a part carried by the lay-and properly position the parter and clamp for their parting and clamping operations.

The movement of the parter and clamp, the hunter and the slide .30 carrying these parts, is indicated by dotted lines in Fig. 1, wherein it will be noted that the parts cited move from their full line positionrearward- .ly towards the outer end of the shuttle box on call for replenishment of filling and then return in an inclined path towards the inner end of the shuttle box as they move to outer position, thereby. producing slack in the spent filling end.
