Application filed. December 13, 1913.

b all whom it may concern Be it known that l, ALoNzo E. Rnonnns, a citizen of the United States, and resident of llopedalc, county of Worcester, State of ll'fassachusetts, have invented an Improve: ment in Filling-Slackencrs for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. A

In looms provided with automatic filling replenishing mechanism the several filling carriers are mounted ready for use in a suitable hopper or feeder from which they are transferred singly to the lay as required. The filling ends from the several filling carriers have to be securely held as the filling carrier is transferred. to the lay and beaten across the loom. The sharp blow of the picker on the freshly supplied shuttle subjeets the filling end to such a shock that it frequently breaks before the filling begins the unwinding from the end of the filling carrier. Consequently, various means have been devised to overcome this difficulty.

The present invention presents an improved means for providing slack in the filling end when required. This is secured in the present invention by not merely releasing or pern'iitting slack in thesgifilline end but by positively slackening up the filling end. In the preferred form of the invention this positive lackening of the end is secured by providing an individlnil end holder for each filling end and giving to it upon the transfer of ts filling carrier a positive movement to carry the end held by it toward the filling carrier, and thus positively slack-en the filling end.

It is essential in this character of device that the filling ends shall not be left loose, but shall be held taut up to the time of the transfer of the filling carrier, otherwise they are liable to be caught in the mechanisin of the loom or entangled with the other filling ends. This is provided for in the present invention by the individual end holders and by providing for their actua tion through connections with the transfer mechanism itself so that the slackening of a filling end is controlled by or through the transfer of its filling carrier from the hopper. These and other features of the invention will appear more fully from the accompanying description and drawings, and

will be particularly pointed out in the claims.

The drawings represent only so much of the mechanism of a loo-1n as is necessary to a disclosure of the present invent-ion, and the mechanism ilhilstrated, and to which an embodiment of this invention is shown as applied, is that of the well known Northrop type of loom.

lln the drawings: Figure 1 is a front clevation and partial section of a filling feeder and adjacent port-ion of the loom together with the parts embodying my invention; Fig. 2 is an end elevation of the parts shown in Fig. 1, without a repetition of some of the parts which are the same for each filling carrier; Fig. 3 is a detailed view showing in a section transverse to the axis of the filling feeder the means for mounting and pivoting the individual end holder.

Reference may be had to my prior Patent No. 1,059,638 granted April 22, 1913 for the general type of filling feeder and connected parts herein illustrated, and as the general construction of the filling feeder and the construction and operation of the means for transferring a filling-carrier therefrom to the shuttle in the lay upon the call for filling replenishment are well known and familiar they need not be here described in detail.

The filling feeder 'or hopper comprises the circular plate 1 with butt-receiving pockets and having its hub 2 mounted to rotate on the horizontal stud 3 fixed in the hopper stand 1- carried by the loom frame. The outer feeder plate 5 is provided with a hub 6 rigidly mounted on the hub 2, and at its periphery is shown as provided with tipholders 7 all as shown in my prior patent.

.lnstead of the usual disk and stud for holding the filling ends and providing slack, this invention provides an individual holder for each filling end positively moved to slacken positively the end upon the transfer of its filling carrier from the hopper or feeder. In the construction illustrated the shaft 3 is extended to the right and. connected by a bracket 8 with the usual transferrer shaft 9 which is also extended to the right for that purpose.

The reduced portion 10 of tl e hub 2 upon which the outer feeder plate is mounted is extended to the end of the shaft A shouldered hub 11 provided with an enlarged annular rim 12 is mounted on the portion 10 of the hub 2, abuts against the outer feeder plate 5 and is held in place by a set screw 13. An annular seat 14 is mounted on the hub 11 abutting against the shoulder thereof, and is held in place by an annular retainer 15 also mounted on the hub 11 and secured thereto by a set screw 16. This seat and retainer constitute the pivotal support for the individual end holders.

The individual end holders are shown as arms each of the same construction, one being provided for each filling end. Each arm 17 is formed at its outer end with suitable means for gripping the filling end. In

the construction illustrated the filling is brought over the end of the arm and wound about a projection 18 thereon. These rms 17 are preferably flat or are flattened at their lower ends and fit within the peripheral radial slots 19 of the annular seat 15. The seat is grooved at its periphery circum ferentially to form open bearings for the pivot pins 20 of the arms 17. The annular retainer 15 is provided adjacent the seat with an annular projecting flange 21 fitting over the periphery of the seat 14 and slotted at 22 to correspond with the slots 19, thus holding the pivot pins 20 in their bearings. The annular retainer 15 is also extended radially at 23 to form astop limiting the swinging movement of the arms 17 toward the filling carriers.

The parts thus described present a simple construction and one which may be readily manufactured and assembled. The slots may be readily cutin the seat and retainer. The seat is then slipped on over the hub 11 and againstthe shoulder. The pivot pins 20 are placed in the arms, the arms drop in the slots 19 bringing the pivot pins, into the open bearings, the annular retainer is slid on over the hub until it abuts against the seat with its slots in radial alinement with the slots of the seat, thus holding the pivots in their bearings. The set screw 16 is then set up and the hub 11 then carries all the parts and may be slipped on over the hub 10 and locked in place by the set screw 13. The other parts to be described connected with the arms are, of course, placed in position before the assembling takes place.

Each arm or individual end holder 17 is providedwith a detent by which it is held in position to maintain the filling end taut. These detents are shown as pawls 24 pivoted at 25, and limited in their movement toward the center by stop pins 26 on the arms. The detents are normally projected toward the center by coiled springs 27 abutting thereagainst and pocketed in seats 28 secured to or formed integrally with the arms. The annular rim 12 is beveled or cam-shaped at 29 on theportion of its periphery toward the arms and the end of the detents is correspondingly cam-shaped or beveled at 30 so that when the detents are freefrom the annular rim and the arms are swung away from the filling carriers the detents by reason of the cooperating cam surfaces 29 and 30 will slide up and snap over and lock upon the annular rim.

Means are provided for positively moving each arm or individual end holder toward the filling carrier, and for this purpose coiled springs 31 are pocketed inthe hub 11 and abut against projections 32 at the base of the arm 17.

The arms 17 if not in outward position are thrown over by the operative against the spring 29, the detent 24 rides over and catches upon the annular rim 12 and then the operative inserts the filling carrier 33 in the seats in the feeder and carries the filling end over the tip holder, draws it taut andsecures it to the free end of the arm 17 This is done with each filling carrier and its filling end. If now the detent 24 be released from the annular rim 12 the corresponding individual end holder or arm 17 will be moved by the spring 31 to carry its free end toward its filling carrier, thus positively forming slack in the run 34 of the filling end, as shown at 35. In the present invention this movement of the individual end holder is controlled by or through the transfer of its corresponding filling carrier from the hopper, and as herein illustrated, by mechanism operated from the transferring device itself. A striker lever 36 is fulcrumed at 37 in a hub formed in the bracket 8 and has its free end 38 bent in and project ing radially within the path of the ends of the detents 24. The opposite end 39 of the striker lever is provided with a pin 40 riding in a slot 41 of one arm of a lever or connection 42 mounted on the transferrer shaft 9 and connected to the usual transferrer arm. 'Hence when the transferrer arm is moved upon the call for filling replenishment and acts to transfer the filling carrier from the hopper the striker lever is I moved to release the corresponding detent 24, thus causing the actuation of the corresponding filling end holder and positive slackening of the corresponding filling end.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
