FILLING-END CONTROLLER.

Application filed March 23, 1927.

This invention relates to filling replenishing looms and is more especially directed to the means for controlling the filling ends on replenishment of filling that they may not be carried into the cloth.

It is now the common practice to provide filling replenishing looms with means for preventing the incoming or outgoing filling end from being taken into the shed with the shuttle on a subsequent pick after replenishment. Should either of the pieces of fill ing end he carried into the shed, defective cloth will result.

The outgoing filling end is very frequently carried with the ejected bobbin and withdrawn from the shuttle box and shuttle eye. but dependence cannot always be placed upon this conditional operation (.Qpecially with some characters or kinds of filling.

The incoming filling end which is usually secured to some fixed point, such as the outer end of the hopper or hopper stand,- presents some difiiculties also in preventing the part of the filling leading from the fixed point to the cloth selvage from being taken into the shed on a subsequent pick following replenishment.

The present invention has for one of its objects to provide means for taking care of and controlling the filling end whether it be the incoming or outgoing filling end. to prevent either from being taken into the shed.

More particularly the present invention provides a filling cnd controller which shall have an oscillatory movement upon a fixed point or pivot and so connected to the lay that upon movement of the latter the filling end controller will be given a sweeping movement to engage and withdraw the filling end from the lay.

The various features of the invention and new combination of parts will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. 1 is a perspective view of a portion of a loom at the replenishing side. provided with the present invention;

Fig. 2 is an enlarged perspective view looking rearwardly and to the right at the replenishing side of the loom, and showing more particularly the filling end controller for removing the incoming filling;

Serial No. 177.570.

Fig. 3 is an enlarged sectional elevation looking towards the hopper or magazine and showing the present invention, the lay being in its backward position; and

Fig. 4 is a detail with parts broken away showing the relation of parts when the lay is in its front position.

The loom frame 1 may be of usual construction and mounted atone side thereof is the hopper stand 2 in which a number of filling carriers or bobbins 3 are carried. The end a of the filling leading from the filling carriers in the hopper is herein shown as carried over a disk 4 and an outer disk 5 and secured centrally of the hopper axis, as at 6, by being twisted about a hub portion at the outer side of the disk 5. These details may be greatly varied, but they illus tratc one means of supplying filling carriers for replenishment of filling and also of securing the filling ends.

The magazine or hopper in the present instance of the invention is shown as of the rotary type and so, as these successive filling carriers are transferred, the filling end a leading from the carrier next to be transferred will obviously be at the lower portion of the disk 5 in case such 'disk be employed. On replenishment of filling, when the filling carrier is transferred from the hopper to i the shuttle, the end leading therefrom and secured at the point 6, will cause the filling end a to take position as indicated in Fig. 1, as the shuttle is picked; that is, the filling a of the incoming filling carrier will take an inclined position above the shuttle box, and unless the length of filling between the cloth selvage and the fixed point be removed, it is liable to drop into the path of the shuttle or the danger zone and be carried into the shed, a condition that is particularly liable to occur when the temple thread cutter parts the filling end at the cloth selvage. or even should the filling end'be broken.

Mounted upon the breast beam of the loom is the temple stand 7 which may have the usual temple thread cutter, so that both the incoming filling end and the outgoing filling end may be severed at the cloth selvage.

Pivotally mounted at 8 is the filling end controller 9, the downwardly extending end portion 10 of which is adapted to engage the filling end a of the incoming fillin when replenishment has been effected. T e piv eta]. support. 8 of the controller 9 is prefen ably, though not necessarily, formed by an arm 11 which may be secured by a nut 12 to the stud shaft 13 01? the rotary hopper.

Secured at the trout of the loom and preterably on the breast beam is a thread catcher it which may be constituted as a wire finger bent upwardly at 15 and then reversely bent, as at 16, to form a catcher tor the filling; ends delivered to it by the filling end controller 9. In the present instance, the catcher 14 is secured by a bolt 17 to a fixed part of the loom and extends rearwardly a suliicient distance to permit the swinging controller 9 to carry the end filling into engagement with the catcher when filling replenishment has been effected.

In order that the fillingend controller 9 may be given sweeping action transversely of the lay to engage the incoming filling end when filling; replenishment etleoted, the present invention contemplates that. the till ing end controller shall be so connected to the lay that its filling end will sweep transversely over the path oi movement ofthe incominp filling end on the first pick of the shuttle :tollowing replenishment, and to insure that the engaged filling end shall be swept trontwardly into control oi. the filling end g atherer. the means for actuating the filling end controller is contrived to impart to the lower end thereof a sweep inc" movement trontwardly to carrythe end oil the engaged filling); into the thread gatherer.

In the present ins ance of the invention, the shuttle box 18 which is carried by the lay 19, as usual, has projecting" upwardly therefrom the rigid arm 20 having a lateral extension 21 provided with. an opening; 22 through which opening 22 extends the lilling end controller 9. The rigid. arm 20 may be secured to the top of the shuttle box or to the lay in any suitable position by means of a screw or other securing means 23. It will be noted that the filling); end controller E), which is pivotally mounted at the lived point 8, is engaged with the actuating; arm or member 90 at a point between. the pivot oi the controller and its lower filling engaging end, the result being that the lower end portion of the controller will be given a movement: in the same direction as the lay but at a greater speed, to the end that on frontward movement the filling; end engaged bythe filling end controller will be swept frontwardly and intov the control of the thread catcher.

From the construction thus far described it will be apparent that the incoming filling; end will be enga ed by the filling end controller through its sweeping action and at a greater speed than the lay movement will he carried frontwardly and held in its front position by the thread gatherer, so that at a subsequent period the temple thread out-- iho outgoing filling end is withdrawn from the lay in a corresponding manner to that of the incoming; filling end; that is to say, the outgoing' filling end is engaged by a ya controller which is pivotally mounted at a lined point and is given a swinging; i'i'iovoment in a. direction transversely of the lay to withdraw the filling; end from the lay and shuttle box.

i .1 indicated more clearly by l and 3. the outgoing filling end controller 24 is pivotally supported at 25 upon a bracket 26 which secm'ed to the loom trance as by the bolts and the top edge portion of the end controller 24. is provided with a series of teeth 28. A light spring; 539 normally holds the controller 94 in its normal. position to receive over the top thereoi the ejected filling; carrier.

Fx ending down *ardly from the controller 52 i is the lug; having an eye through which exteuc s an actuating; roe 31, the outer portion of which is screw-threaded and pro vided with adjusting nuts 82, lhe actuatinsz rod 231 constituted. as rigid member and eiztei'ids rearwardly and then upwardly, as at 33, and is fixedly secured to the lay 19 at. ill, the ellect being; that on each backward movement of the lay, the controller 2-1- will be given a sweeping; movement transversely of the lay in a direction to withdraw the filling; end from the danger zone where it would. be liable to be carried into the shed by the shuttle.
