FILLING ATTACHMENT FOR LOOMS.

Application filed February 19, 1926. Serial No. 89,490.

This invention relates to looms and has special reference to an attachment for filling replenishing looms, the attachment being in the form of a guide for loom bobbins or filling carriers arranged to direct the depleted bobbin from the shuttle into the bobbin can common to such looms.

The invention is applicable to any of the usual types of automatic filling replenishing looms and in such looms it is common for the loom to be provided with a hammer or transferrer which, at the proper time, forces the depleted bobbin from the shuttle and into the bobbin can. It frequently happens that,-such looms being often without proper guide means for the bobbin, the latter is thrown outside of the can onto the floor or'into the mechanism of the'loom.

One object of the present invention is to provide an improved guide arrangement for looms so constructed that the bobbin cannot drop on the floor or be thrown into the machinery.

Attempts have been made to provide guide means on the lay-of the loom for this purpose but such guides are found to be unsatisfactory because the bobbin does not, at all times, drop from the guide upon the latter reaching .proper cooperative relation with the can but frequently drops from the guide while the 'lay. is out of position so that the bobbin falls outside the can. Other attempts have been made to position stationary guides on the frame of the loom but these are inefficient for the reasons given above.

A second important object of the invention is toprovide a novel arrangement of guide for-the depleted bobbins which is yieldingly mounted on the frame of the loom in such manner that the opening in the lay through which the bobbin drops will remain an appreciable part of the movement of said lay in'registry" with the mouth or inlet end of the guide.

In such looms the depleted bobbin when ejected from the shuttle still carries a certain small amount offlfilling or weft and this results in a loose end which is sometimes caught and drawn back into the shed producing an imperfection in the weave.

A third important object of the invention is to provide a novel means for preventing this weft end from being drawn back nto the shed and to thereby eliminate the imperfections resulting from this cause.

W th the above and other objects in view as w1ll be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed. Y i

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a detail elevation of a portion of a filling replenishing loom showing the invention applied thereto.

Figure 2 is axplan view of the attachment 4' Figure 5 is a detailview of a portionrof the guide, the view being taken looking into themouth of the guide and showing the filling catching bristles.

The loom here shown is of ordinary construction and has a frame 10, lay 11: picker stick 12, magazine 13 and bobbin transfer mechanismi i14. Also the lay is provided with an opening 15 through which the depleted bobbin may pass and the usual shuttle 16 and bobbins 17 are employed.

The construction and operation of these parts being commonly known and not forming any part of the present invention it is not deemed necessary to further describe the mechanism of the loom or its operation other-than to say that the lay oscillates under the influence of the proper mechanism of t'he loom and whenin its forward position the mechanism 14"acts, whenever the bobbin in the shuttle is depleted to a certain extent, to transfer a full bobbin from the magazine to the shuttle and at the same time to eject the depleted bobbin which is forced downwardly through the opening 15.

so that the slots 21 cross the slot 18, bolts being used to secure the base to the frame. By this means the base may be adjusted on the frame both vertically and horizontally within the limits allowed by the lengths of the slots. Extending rearwardly and outwardly from the base is an arm 23 which terminates in a head 24 in which is fixed one end of a shaft 25. On this shaft is revolubly mounted a pair of sleeves 26 from each of which extends a strap 27 and secured on these straps, as by rivets 28, an under or rear guide plate 29, as shown in Fig. 1. Forward of and spaced from this guide plate is a front or top guide plate 30 and these guide plates are both inclined forwardly and downwardly from their upper edges, the top guide plate being also inclined from its up per edge forwardly and downwardly away from the under guide plate. The ends of these guide plates adjacent the frame are connected by a connecting plate 31, Fig. 2 and, in construction these plates may, if desired, be pressed from a single piece of sheet metal. There is thus formed a chute flaring from its upper or mouth'end to its outlet or lower end.

Fixed on the shaft 25 is a collar 32 and surrounding this shaft is a coiled torsion spring 33 having one end fixed to the collar and its other end engaged with one of the straps 27 to constantly urge the chute rearwardly, a stop 34 being formed on the head 24 to limit the movement of the chute rearwardly and one of the straps 27 normally rests against this stop. On the lay 11 is a plate 35. With this construction the plate 35, when the lay is in forward position, engages the under guide 29 and rocks. the guide chute forwardly a short distance and it is while in such contact that the depleted bobbin is ejected so that,it can only pass down the chute and into the can 19, the latter being located below the delivery end of the chute.

In order to prevent the weft or filler end 36 from being drawn back into the shed after the depleted bobbin is ejected there is provided on the upper guide plate 30 a brush back 37 which carries brush bristles 38 which are angularly disposed to and bear against the under guide plate. By this means the end 36, upon ejection of the bobbin, engages in these bristles, the inclination *of the bristles permitting the bobbin to passfreely through the same, and is thereby prevented from being drawn back.

There has thus been provided a simple and eflicient device of the kind described and for the purpose s ecified.

It. 's" obvious t at minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is. not, therefore,

desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described'the invention, what is claimed as new, is:

1. A guide attachment for depleted bobbins in automatic filling replenishing looms comprising a base adapted to be secured to a loom frame, an arm projecting rearwardly therefrom in the direction of the loom lay, a shaft projecting laterally from the end of said arm, a pair of sleeves on said arm, straps extending from said sleeves, a guide chute, carried by said straps, a collar fixed on said shaft, a torsion spring on said shaft having one end fixed to the collar and the other end engaged with one of the strapsto urge the chute in one direction around'said shaft, a stop on said arm limiting the movement of said chute under the influence of said spring, and filler catching bristles in said chute extending downwardly from the upper side of said chute in contact with the' bottom side thereof.

2. A guide attachment for depleted bobbins an automatic filling replenishing looms comprising a base adapted to be secured to a loom frame, an arm projecting rearwardly therefrom in the direction of the loom lay, a shaft projecting laterally from the end of said arm, a pair of sleeves on said arm,
