SPECIFICATION forming part of Letters Patent No. 552,354, dated December 31, 1895. Application 5165 October 15,1895. Serial No. 565,815. (No'mud51 To all whom it may concern:

Be it known that I, FLORENCE M. DAY,'of, Hopedale, county of Worcester, State of Massachusetts, have invented-an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

In-United States Patent No. 6532,940Jgrantr6 edto James H. 'Northrop, a loom is shown provided with filling changing or supplying mechanism, wherein an in'termittingly-operating filling-feeder positively brings each filling-carrier, shown as a bobbin, into position I 5 under. the pusher, to be inserted in the shuttle, a stop against which rests the head of the bobbin next to be acted upon by the pusher co-operating with the feeder. The 'fillingfeeder in said patent is composed of two disks '20 attached to a sleeve mounted on afixed stud, a ratchet connected to the sleeve or a disk being engaged by a pawl mounted upon a spring-actuated pawl-carrier deriving it's motion from a projection carried by the lay.

.2 5 The disks constitute ahopper for the bobbins or filling-carriers, as they will be hereinafter termed, and the coiled spring to rotate .the-

hopper naturally becomes weakened by such .rotation, and it is necessary to provide means for restoring its. energy. In thepatent re- 'ferred to such means are provided by thepawlcarrier having a pawl to engage the ratchet to which the spring is attached, the pawl-carrier being so positioned on the hopper that it 3 5 comes into the path of a roll or projection on the lay. On the transfer of a filling-carrier to the shuttle, the lay being forward, the hopper rotates by means of the coiled spring, and the pawl-carrier controlling the spring turns 0 with it, bringing the end of said pawl-carrier directly into the path of the roll on the lay. -When the laymoves back the roll raises the pawl-carrier and turns or winds upthe spring throughthe pawl and ratchet, a separate dog 4 5; or detent preventing backward movement of the filling-feeder. Evidently, in order-that the pawl-carrier shall always move its pawl back far enough to wind the spring before en- ..gaging the ratchet, it is necessary that the roll or projection on the lay control the pawlcarrier for a short time after the. pawl has tion, which sometimes takes place nearly two hundred times per minute.

This invention has for its object the production of means for overcoming this constantly-recurring engagement of the pawlcarrier' and lay, and for this purpose I make use of a roll which, instead of being stationary or rigid'on the lay,- is attached to a short rocker-lever mounted on thew-lay andunder thecontrol of a suitable spring, which nor mally holds the roll down and out of engagement with the pawl-carrier ora part thereof when the lay movesforward, the hopper being held inoperative.

When a filling-carrieris'transferred to the shuttle, however, the, pawl carrier will be moved during the partial rotation of the hop- .per into the path of theroll, and, engaging therewith, the friction will cause'the rockerlever to be moved against its controllingspring when the lay moves back, thereby raising the roll into operative position to move through a higher path and act upon and lift 8: orswing the pawl-carrier. By the time the lay has moved back the roll will have swung the pawl-carrier enough to tighten the hopper-spring and cai ry the pawl back into'engagement wanes ratchet, and when the lay comes forward again the rockingleven'undcr the stress of its controlling-spring, will move back into normal position, movingits roll out of the way of the pawl-carrier and remaining in such position until again brought intoaction by the transfer of another filling-carrier. Figure 1 is a view, partially in section, of the inner end of the hopper or filling-feeder, with the lay back, the lay and breast-beam being shown in section on a plane at right 9 5 anglesto the latter, with the hopper and its operating mechanism in normal inoperative position. Fig. 2 is a similar view, the lay being shown as forward, however, and the hopper is supposed to have been rotated by its spring after a filling-carrier has been trans-v 'ferredgte the shuttle-box, the tighteningdevices for'the hopper-actuating spring being shown as in'position to be operated by the {v lay on its back stroke. Fig. 3 is a longitudinal sectional detail of the filling-feeder and elwatioh thereof in weft-end holder, taken on the line :20 m, Fig. 1', and'looking-to the right, one filling-carrier being shownin position by dotted lines. Fig. dis an enlargedendelevation of the roll-carrier and its-roll, its operative position being indicated by dotted lines; and Fig. 5 is a front normal inoperative position.

consists essentially of a disk or plate a notched at 2 to receive the heads of the filling-carriers I), (see Fig. 3,) and a second disk or plate a, having a series of grooves 5 and provided with. a series of springs a serves'to hold the tips of the filling-carriers, as in said patent, the hub a of diska'having a dog a extended through a slot in the hub and entering an annular groove a in a stud of fixed relatively to the stand a by a nuta so that the hub and disk may be rotated interinittingly on the stud (t and the ratchet-teeth a on the disk a may be and are substantially as in the patent referred to. A weft-end support Z)" is fast on a sleeve I forced tightly into the open end of the hub a and loose on the'stud a, said support having' a weft end holder b the support and holder rotating in unison with the filling-carrier, feeder or hopper.

The foot of the stand a is attached by suitable bolts to a block or plate resting on the breast-beam A said stand having around a portion of its periphery an attached guard or shield c overlapping the heads of the fillingcarriers supplied to the feeder, the endmost filling-carrier always resting against the stop 13, (shown in dotted lines, Figs.:l and 2,) directly over the sh uttle box of the lay A when the latteris in its forward position'toward the breast-beam.

Theinner end of; the. Stud projecting through the stand a is reduced at a? (see Fig. 3) to form the fulcrum for a pawl-carrier, (shown clearly in Figs. 1 and 2,) the hub. f

thereof carrying a coiled spring 8, one end of v which is attached to the pawl-carrier, while its other end is fixed to the stand a or some other stationary part, the spring moving the pawl-carrier to effect the rotation of the fillsome part thereof (herein shown as the reeding-feeder in the direction of arrow- 25,. Fig. 1,

. or in its forward direction, the pawl-carrier and-pawl being moved in the opposite direetion by means to be described.

and 5,) extended through the lower preferably forked or bifurcated end of a rocker-lever h, which straddles the ears g, as best shown in Fig. 5. Aspring s is coiled around the pin 9 and held at one end to one of the ears 9, or-to some fixed part of the stand, the otherend-of the spring bearing against the rocker-lever h and tending to normally hold it in full-lineposition, Figs. 1, '2, and 4. The said lever is notched at its upper end to receive a roll h, mounted on a pin h and preferably free to rotate, said roll being adapted, when the lay is forward, to contact with the under-side'of the tail f 3 ofthe pawl-carrier when the latter is in the p'ositionshowu in Fig.2, the fillingfeeder having been moved forward by the spring 3 upon the transfer-of a filling-carrier Now as the la'y moves back the friction between the roll h and the tail f 3 will turn the rocker-lever it upon its pivot up into dotted-lineposition, Figsl'and 4, so that it will move he. higher path as the lay continues its backward movement, and when the .roll h passesalong tothe convex portion 21 of the tail f the latter will beraised into position shown in Fig.1. 'lhe'pawl fis thus carried back -to engage a new portion of the ratchet a, winding up and restoring the power of the feeder-actu atin g spring 8. Just as soon as the roll h is 'carried' out to theend-of the tail f its spring srestores it to its normal inoperative position, out of range ofthe tail, and on subsequent strokes of the lay it will not contact therewith until the filling-feeder has again moved forward at the transfer of the next filling-carrier to the shuttle, when the foregoing operation will be repeated.

By the construction hereinbefore described it will be obvious that the movement of the filling-feeder due to transfer. of a filling-car rier will act through the pawl-carrier to automatically move the roll h into operative position to reset the feeder-actu ating spring, and when this has been accomplished the roll is automatically returned to inoperative position.
