Patented Jan. 2, 1934 UNITE oF'Ficf FILLING CARRIER SUPPORT FOR LOOM Luther E. Gatlin, Ncwberry, S. 0., assignor to Draper Corporation, Hopedale, Mass, a corporation of Maine The present invention relates to filling replenishing looms, of the type employing a rotary hopper for carrying a reserve supply of filling carriers which are automatically transferred, one at a time as needed, into the shuttle.

One of the problems in connection with the successful construction of the rotary hopper type of filling replenishing mechanism is to provide for the proper positioning of the filling carrier next to be transferred and the holding of the same from dropping down or turning around before it is actually transferred to the shuttle. Devices intended to effect the proper positioning of the filling carrier under the conditions men tioned have heretofore been developed. However, I propose to provide a novel and improved form of such device, having certain advantages which will be hereinafter pointed out.

The preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a sectional elevation of a portion of the hopper end of the loom; and

Fig. 2 is a view, partly in plan and partly in section, of the mechanism shown in Fig. 1.

The loom to which my invention has been applied includes the reciprocating lay 1 carrying shuttle box 2, shuttle 3 operated by picker stick 4, the filling replenishing mechanism to which further reference will be made, and other well known mechanisms which form no part of the present invention and need not be illustrated or described.

The filling replenishing mechanism includes a rotary hopper 5 for holding a reserve supply of filling carriers 6, the hopper being rotated step by step to successively present the filling carriers to the position occupied by the filling carrier 6, directly over the shuttle box. A transferrer '7 is pivoted on a fixed stud 8 in the hopper stand 9, and is normally urged in a counterclockwise direction, Fig. l, by a coiled spring 10. The transferrer shown is provided with a head 11 and a laterally and downwardly extending portion 12 engageable, respectively, with the butt and tip of the filling carrier 6'. The transierrer is operable by a dog 13 which is pivoted thereto at 14 and movable into the path of a hunter 15 on the lay by suitable usual devices, not disclosed herein.

The loom, including the filling replenishing mechanism thus far described, is not new and is not, per se, of my invention.

The filling carriers 6 in the hopper, as they assume the position 6', have a tendency to drop down out of the pockets 16 in the hopper, and

then to rotate about their own axes, dueto the vibration of the hopper incident to operation of the loom. It is to the proper holding of the filling carriers in the hopper that my invention pertains.

Rigidly fixed to the stud 8, as by means of a set screw 1'7, is a rearwardly extending arm 18, the arm being adjustable about and along the axis of stud 8. At its rearward end, the arm 18 carries a laterally extending pin 19 secured in place by a set screw 20. A holding member constituted by a finger 21 is slotted at 22 iorengagement with the pin 19, the finger 21 being positioned substantially on a radius of the filling carrier 6, next to be transferred, and being slidable along such radius.

The finger 21 is movable from its normal full line position shown in Figs. 1 and 2, where it contacts with the filling carrier 6' and positively holds the latter in proper position, to the dotted line position shown in Fig. 1, where it is entirely out of the path of the transferrer. The finger is so moved during the transferring operation.

For normally holding the finger in its rearward, filling carrier supporting position, and removing it at the proper time, I provide a lever 23 pivoted on a pin 24 in arm 18 and engageable with the transferrer. The lower arm of the lever 23 is pivotally connected to the forward end of finger 21, as by a cotter pin 25 passingv through the lever and through the finger. The upper arm of the lever 23 is preferably made in two parts, and one of the parts, 26, extends rearwardly and bears on the top of laterally extending portion 12 of the transferrer.

When the head of the transierrer is up, as shown, lever 23 will serve to hold the finger 21 in contact with filling carrier 6, as above stated. However, when the transferrer commences to move downwardly it releases lever 23 and the weight of part 26 will cause the lever to rotate in a clockwise direction, Fig. l, and withdraw the finger from contact with the filling carrier.

It is noted that when the finger is in its final withdrawn position it deviates slightly from the radial line along which it is supposed to move. One important advantage of having the finger move radially of the filling carrier is that, then, the normal position of the finger may be made adjustable to accommodate filling carriers of larger or smaller diameter by merely making the length of the finger itself adjustable.

Accordingly the slight deviation from a true radial position when the finger is completely withdrawn is immaterial. The desired adjustment may conveniently be made by forming the forward end of the finger as a threaded rod, received in a threaded hole in the body portion of the finger, as indicated in the drawing.

An important advantage of supporting the holding device on stud 8 is the convenient manner in which the finger may be made bodily adjustable up and down and axially of the filling carrier.

It is, of course, to be understood that the'particular embodiment of my invention herein disclosed is out illustrative of one manner in which my invention may be carried into effect, the true scope of the invention being defined inthe appended claims.

I claim:

1. In a replenishing mechanism for filling replenishing looms, a hopper for holding a reserve supply of filling carriers, a fixed stud, a transferrer pivoted on said stud, an arm fixed to the stud, a finger reciprocatably. supported by the said. arm for engagingthe filling carrier next to be transferred and holding it in place in the said hopper, and means. for withdrawing. the said finger from engagement with the filling. carrier during the transferring operation.

2. In a replenishing mechanism. for filling replenishing looms, a hopper for holding a reserve supply'of filling carriers, a. transferrer, an ad.- justable filling carrier supporting finger slidably mounted formovement radially of the filling:

3. In a replenishing mechanism for filling're plenishing looms, a hopper for holding: a reserve supply of'filling carriers, a transferrer, a

filling carrier supporting member-slidably mounted for movement radially of the filling carrier next to be transferred, and means for normally holding the said member in contact with saidfilling carrier toholdthe latter in place in the hopper, saidmeans withdrawing the said member from engagement with said filling carrierduring the transferring operation.

4. In a replenishing mechanism for filling replenishing'looms, a hopper for holding a reserve supply of filling-carriers, a-transferrer, amember slidably mounted-for movement radially ofthe filling" carrier next to be transferred, means operable by said transferrer for normally holding the said member in contact with said filling carrier to hold the latter in place in the hopper, said means acting to withdraw the said member during the transferring operation, and means for adjusting the position of the said member to accommodate filling carriers of larger or smaller diameter.

5'.
