FILLING-FEEDER FOR AUTOMATIC LOOI VIS.

SPECIFICATION forming part of Letters Patent No. 759,146, dated May 3, 1904.

Application filed February 17, 1904. Serial No. 194,019. (No model.)

Toall whom it raw/y concern:

Be it known that I, EVERETT SVVoon, a citizen of the United States, and a resident of Hopedale, county of Worcester, State'of Massachusetts, have invented an Improvement in Filling-Feeders for Automatic Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to looms wherein the running shuttle is provided automatically with fresh lilling from a reserve supply contained in a filling-feeder. Such a loom is shown in United States Patent No. 529,940 and others of later date, the filling-carriers being sustained in an intermittiugly-movable feeder and brought one by one into position to be transferred to the shuttle. The filling ends are made fast to a suitable holder at the outer end of the feeder, so that the filling end of a freshly-transferred filling-carrier will be held when the shuttle is first picked across the lay. It has been found in practice that some slackness of the filling end is desirable when the transfer and following pick of the shuttle take place in order to obviate breakage due to the sudden shock or strain thus brought upon the fresh filling, and various devices have been constructed to provide for such 'slackness of the filling end at the desired time.

This invention has for its main object the production of novel means for effecting such slackening of the filling endleading from the filling -carrier next to be transferred, the other filling ends remaining taut until slackened in their turn. In connection with such novel feature I have also provided means for holding with equal facility either bobbins or cop-skewers and in such manner that the slackening of the filling end can be readily and automatically effected.

Certain features of construction relating to the tip-holders for the filling-carriers. while shown and described herein in connection with other parts of the mechanism, are not claimed broadly, as they are not of my invention.

The various novel features of my invention will be fully described in the subjoined specification, and particularly pointed out in the following claims.

Figure 1 is a front elevation and partial section of the filling-replenishing mechanism of a loom of the Northrop type referred to with a filling-feeder embodying one form of my present invention, the filling-end holder, of usual construction, being shown in dotted lines. Fig. 2 is a transverse sectional detail of the mechanism shown in Fig. 1 on the irregular line 2 2 thereof looking toward the left. Fig. 3 is a partial inner side elevation of the outer-end plate of the feeder, showing the tip-holders mounted thereon. Fig. i is an outer side elevation of a portion of said end plate. Fig. 5 is an enlarged face view of one of the tip-holders; and Fig. 6 is a sectional view thereof on the line 6 6, Fig. 5.

The stand A fixedly mounted on the breast beam A and having a circular flange c and a horizontal stud 10, on which is rotatably mounted the hub to of the inner end plate ('0, the end-holding means mounted to rotate with and at the out-er end. of the feeder and including a disk 7/ and stud b, the transferrer mounted to rock on the stud f, and the tipde gi'essing' arm 21 may be and are all substantially as in Northrop looms and operate in well-known manner.

The plate a is provided with peripheral pockets 2, Figs. 1 and 2, to receive the heads of the bobbins or cop-skewers, a filling-carrier 5 being shown in dotted lines, Fig. 1, the filling-carriers being held in the feeder in a circularly-arranged series. The plate a is also circular, and its huba is connected with the hub a, so that the plates 6! and a will rotate in unison, the feeder being rotated intermittingly by well-known means which form no part of my invention and which consequently are not described herein. Said plate a is provided with radial openings (1/ located opposite the pockets 2 and extending inward from the periphery of the plate, and on the outer side of the latter adjacent the inner ends of the openings an annular lip or rib a is formed, and spring-seats (1. arranged in a circle, span the openings between their ends, being formed integral with the plate on its outer side. A circular socket 5 is formed in the inner face of each seat to receive one end of a spiral spring 8 Fig. 1, the other end of the spring cooperating with a tip-holder movably mounted in each opening (0 and arranged to hold either the blunt tip of a bobbin or the sharper-pointed tip of a cop skewer. One of the holders is shown separately in face View 1n Fig. 5 and in section in Fig. 6, each holder being made as acasting having an elongated body la movable freely between the sides of an opening (0 the innerv end of the body being shaped to present a deep and slightly-flared transverse groove h to receive and rock on the lip or rib a as a fulcrum. The outer end of the body is curved outwardly in the direction of its length at h and provided with lateral ears h it of unequal length, as herein shown, the longer ear, it, having a notch or groove it formed therein. When the holder is positioned onthe plate a, the ears extend laterally across the outer face of the plate at each side of the opening a and limit inward movement of the holder, the extension ]t projecting beyond the outer face of the plate. (See Fig. 1.) The holder is inserted under the corresponding spring-seat a and the free end of the spring 8 enters arecess If in the back of the holder, maintaining the latter pressed inward with its ears against the plate, while the flared walls of the groove h permit slight rocking of the holder on the rib a, the latter positioning the holder radially on the plate a. Thus the tip-holders are movably mounted on and retained in position on the plate without screws or bolts. The holder is thickened at 72 (see Fig. 6,) and the face thereof is recessed or depressed to form 'an elongated U-shaped seat it, having its open end turned toward the outer end of the holder. This seat is so shaped to present an inner rest 40 and an outer rest 41, the rests being formed by shaping the side walls of the seat h in such manner that the rather blunt tip end of a bobbin will enter either rest and be supported therein. the spring .9 pressing the bottom of the seat against the endof the bobbin when in either rest. WVhen the bobbin is placed in the feeder, its head is seated in a pocket 2 of the plate a and its tip is pushed inward into the inner rest 40, the bobbin when thus inserted pushing the holder outward and compressing the spring 8X. By reference to Fig. 1 it will be seen that at such time the bobbin is not parallel to the axis of the feeder, but is inclined with relation thereto, the tip of the bobbin being nearer the axis. The filling end tis led from the tip of the bobbin diagonally into the notch h in the ear [L13 and thence over theperiphery of the disk 6 to the stud 5 around which'it is wound,'the filling end being thus held taut enough to prevent interference with its fellows.

In order to support the sharp or pointed tip of a cop-skewer, a longitudinal groove If is made in the. bottom of the seat it, said groove having a pit or rest 50 at its inner end and a second pit or rest 51 nearer its outer end, each adapted to receive and support the tip of a cop-skewer. When a cop-skewer is "inserted in the feeder, its tip is pushed inward into the inner rest 50, so thatthe tip is nearer the axis of the feeder than is its head, seated in the'opposite pocket 2 of plate 20, and the filling end is led off, as before described, in

the guide or notch h to the holding means. In order'to slacken the filling end of the filling-carrier next to be transferred to avoid undue strain on the filling when the shuttle is picked immediately following transfer, I have provided means to cause movement of such filling-carrier in and relatively to the feeder to bring the tip nearer the guide h. Such movement gives up a small portion of filling and provides the requisite slackness. To this end an arm is fixedly mounted on the outer projecting end of the stud f and extended rearward, said arm having adjustably secured to it by a clamp-bolt81 an extension 82, having a downturned end 83, Fig. 2, provided at its extremity with a lateral stud or roll 84. The arm 80 is longitudinally slotted at to receive the bolt 81, so that the extension 82 can be adjusted in order to place the roll 84 in proper position. This roll is so adjusted or set that it will engage the tip end of the leading fillingcarrier of the series as it is moved forward by the feeder into transferring position, and as the filling-carrier moves forward the roll will depress the tip thereof and move it away from the axis of the feeder. An inspection of Fig.

2 will make this clear, the roll 84 being shown as ready to depress the tip of the filling-carrier 6 when it is moved forward into the position of the filling-carrier I), the latter being ready for transfer and having already been depressed. If bobbins are used, the tip of each will be moved from the inner rest 40 to the outer rest 41 of the holder, the spring .9" yielding to, permit such movement, and not only is the bobbin then brought into proper relative position to be engaged by the transferrer, but its filling end will be slackened, as shown at t Fig. 1. A similar movement is effected in the case of cop-skewers, the tip of each one being moved from the inner rest 50 to the outer rest 51, with consequent slackening of its filling end. The action of the tip-holder spring causes the tip to be operated equally well whether the inner or the outer rest of the holder engages and supports the tip of the filling-carrier. Owing to the smaller size of a cop-skewer tip, the roll 84: must be adjusted to a lower position than when bobbins are used, and this can be accomplished by the adjustable connection between the extension 82 and arm 80 and by the set-screw 86, which secures the hub of the arm on the stud f.

My invention is not restricted to the construction herein described, for, so far as I am aware, it is broadly new to change the position of a filling-carrier in and relatively to the feeder prior to transfer therefrom, and ac cordingly various changes or modifications may be made without departing from the spirit and scope of my invention.
