THREAD-COLLECTING MEANS FOR AUTOMATIC LOOMS.

To all whom it may concern:

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Thread-Collecting Means for Automatic Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to automatic filling-replenishing looms wherein a fresh supply of filling is inserted in the working shuttle while the loom is in operation, and it has for its object the production of means to collect promptly and automatically the filling-ends left by the replenishing operation and to retain them out of the way of the shuttle or other moving parts of the loom.

In the Northrop type of loom the fillingcarriers or bobbins are held by their butts and tips in a rotatable hopper, from which they are transferred to the shuttle as required, the filling-ends being led outward around a disk-like guide attached to the outer end of the hopper and thence to a central holding /st-ud or knob. rangement holds the end of the filling while the shuttle is picked after replenishment, and it also provides the requisite amount of slackness to prevent breakage, and after 'the new filling is carried through the shed the filling-end is severed adjacent the cloth at the replenishing side. This severed fillingend is still held at the outer end of the hopper and hangs down therefrom, so that it is necessary for the weaverto wind it around the stud or knob to keep it out of the way ofthe shuttle, as otherwise it would tend to be carried into the cloth. The weaver should thus attend to the filling end imme diately after each operation of the replenishing mechanism, and the accumulation. of yarn on the holding stud must be removed from time to time in a tangled bunch or mass, as otherwise the loose ends would tend to shake off and hang down in the Way of the shuttle.

In accordance with my present invention I haveprovided means for collecting Specification of Letters Patent.

Application filed December 13, 1911.

Serial No. 665,423.

promptly and automatically the severed filling-ends into the form of a loose rope depending from the central stud of the endholding means, and retaining such ends at a point toward the front of the loom, at such a distance from the shuttle path as to be out of the reach of the shuttle as it is picked back and forth. This loose rope of waste filling can be cut off and removed from time to time, but the weaver is relieved of the necessity of looking after a filling-end when replenishment is effected; the waste does not collect in an indiscrimi nate, tangled mass on the holding stud, and it can be quickly and easily removed.

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

Figure l is a top plan view of the re lenishing side of an automatic loom oi the Northrop type, with one embodiment of my present invention applied thereto, a part of the hopper and the end-holdin means carried thereby being shown in dotted lines; Fig. 2 is a transverse sectional detail on the line 2-2, Fig. 1, looking toward the ri ht, showing the guiding means for the fillingend ad acent the mouth of the replenishing shuttle-box; Fig. 3 is a similar detail, on the line 3-3, Fig. 1, looking toward the right, showing in elevation the stationary retainer for the filling-ends, and the device on the lay by which the severed filling-ends are pushed frontward along the retainer; Fig. 4 is a front elevation of the replenishin end of the lay with the platelike pusher tiereon by which the severed filhng-ends are ushed frontward on the retainer, the latter eing shown in section, taken on the line 4 4, Fig. 1.

The lay A having a shuttle-box B at the replenishing side of the loom, the threadoutling temple C, Fi 1, to sever the fresh filling-end adjacent t e selvage of the cloth, the rotatable hopper to contain the fillingcarriers or bobbins in reserve, and com rising essentially the connected disks or p ates D, E to sustain the bobbins at their butts and tips; the end-holding means oonsistin of the bell-like uide disk F and centre stud or knob G own only in dotted lines,

Fig. 1) the transferrer H, and the stud I on which it is mounted to rock, are and may be all substantially of well known construction, such for instance as are shownin tion or web 3 of such arm has a series of teeth or notches 4 in its upper edge, the web tapering from front to rear, as does the flange 5, which latter is horizontal for the greater part of its length, and also toothed or notched on its inner edge, at 6, said web being at the inner side of the flange, as clearly shown in Figs. 1 and 3. The two series of teeth preferably alternate, or are staggered with relation to each other, with their vertical faces toward the front of the loom, the retainer as a whole being extended rearward just above the path of movement of the top of the shuttle-box B, Figs. 3 and 4, and inside but adjacent the periphery of the guide F.

When a bobbin is positioned for transfer by the feed of the hopper that part of its filling-end between the hopper disk E and guide F will ride forward over and rest upon the toothed edge of the flange 3, near its rear end, as will be apparent from an inspection of Fig. 3, and ust after replenishment, when the shuttle has been picked from the box B, the fresh filling-end will be positioned substantially as indicated at T, Fig. 1.

A bracket 7 fixedly mounted on the front of the lay near the outer end of the box B has attached to it a pusher, shown as a flat late 8 frontwardly extended and moving ust beneath the web 5 of the retainer, the front edge of the pusher being notched or toothed at 9. When the lay beats up to front center the toothed edge of the pusher is about in dotted line position, Fig. 1, and from a point immediately under the retainer extends inward quite a distance. As the lay swings rearward the edge 9 of the usher will move back behind the severed lingend, the free end of which by that time will have dropped down and depend from the retainer, see Fig. 4, so that on the next beatup the pusher w1ll engage such depending part of the thread and will push it forward along the retainer. The teeth 4 and 6 will catch the filling-end thus pushed frontward and will kee it from bein shaken rearward, and w ile the said not be retained in its'extreme frontward pglling-end may sition on the retainer the 'first time it is pushed forward it cannot go back very far, and on a subsequent beat-up of the lay the pusher 8 will move the filling-end to its extreme frontward position on the retainer, substantially as indicated by dotted lines at T", Fig. 3.

It will be remembered that while the severed filling-end is held by the stud or knob G it hangs loosely therefrom, bends around the periphery of the guide F, and passes over the toothed retainer, its loose end hanging down therefrom, all as shown in Fig. 4, partly in dotted lines, and the pusher is toothed at 9 in order that it may more securely control the loose, hanging end of thread as the lay beats up. Manifestl the teeth 9 prevent lateral movement 0 the loose end of thread after it is engaged by the pusher, and as the. filling-end 1s pushed frontward along the retainer the upright.

faces of the teeth thereon prevent any material retrograde movement of the filling-end.

As the bobbins are transferred one after another the severed filling-ends will be gradually collected in a loose rope or chain at the front of the retainer, and held thereby at such a distance from the shuttle path that there is no possibility of the shuttle catching and taking back a filling-end into the cloth. The collected ends will be very slowly Wound up on the knob or stud G as the hopper is rotated step by step, but it will be apparent that the loose rope or chain can be quickly unwound from such stud, or it can be cut from time to time before it has an opportunity to accumulate on the stud to any extent.

I have provided means at or near the mouth of the replenishing shuttle-box to control the filling-end thereat, so that the loose extremity of the severed filling-end cannot drop into the shuttle-box. To this end I provide the inner end of the front. box

wall at its top with a frontwardly extended shelf-like support 10 having at its front end an upturned stop 11, and atits rear end a second stop 12, preferably undercut, as

shown in Fig. 2, the top of the said stop being frontwardly and upwardly beveled, as

It will be seen from an inspection ofFigs. I

1 and 2 that the backof the casting of which the support 10 forms a part is ing upwardly and frontwardly inclined from the bottom. of the recess K, the part 17 being slightly concaved and extending upward and forward from the incline 16,- As shown in I roaopa'a Fig. 2 the concave surface 17 spans the corner between the lay raceway and the inner box B, the filling leading from the moving shuttle to the end-holding means on the hopper, and as the lay swings back the filling-end T will travel up the cam surfaces 16, 17 and itwill be thereby directed upward and frontward, first against the convexed rear end 14 of the support casting, and then over the beveled top of the stop 13 onto the'support 10, the pull or tension of the filling-end assisting in this movement.

The filling-end T is\shown at the time it has, been directed onto the support 10, in

the manner just described, and it is retained by the stops Hand 12 on the support in front of the shuttle-box B', while the shuttle passes through the shed. On the following eat-up the filling-end will generally be severed by the thread-cutting temple C, or

1 after one or two succeeding forward beats of the lay, the undercut stop 12 preventin the filling-end from moving rearward o the support 10, and when the filling-end is severed it either sags down in a loop between'the support 10 -and the retainer 3', 5,

or'it will draw over such stop and drop down between it and the said retainer. In either case the severedfilling-end will be in the path of the pusher 8 and the latter will push such filling-end frontward along the retainer, as previously described.

Thethread directin devices located at the mouth of the rep 'enishing shuttle-box prevent the filling thread from dropping into or across the shuttle-box after the filling end has been parted,.thus obviating any tendency of the incoming shuttle to become fouled, and such devices also serve to position the filling-end so that when parted or severed it will be in the path of the pusher, to be thereby moved forward along the toothed retainer and held by it out of the way.

, Various changes or modifications in details of construction and arrangementmay be made by those skilled in the art without departing from the spirit and scope of my invention asset forth in the annexed claims.
