SHUTTLE.

Original application filed. November 26, 1913, Serial No. 803,309.

To all whom it may concern Be it known that I, Aznn C. Houei-i, a citizen of the United States of America, residing at Janesville, in the county of Rock and State of Wisconsin, have invented a new and useful Shuttle, (the same being a divisional part of my application iiled in the United States Patent Office November 26, 1913, Serial No. 808,309,) of which the fol lowing is a specification.

lily invention relates to improvements in shuttles employed in weaving shades, the weft of which consists of narrow fibers of wood or other substantial material, and resides in certain peculiar means for acting on the jaws, which grip, hold and carry the slat, fiber, or weft-unit, to release such weftunit, and to thrust the same violently from said aws downwardly into the shed of the loom, or, in short, the invention resides in weit't-unit-liberating means, as hereinafter more fully set forth.

This invention is applicable to a loom such as that described in United States Letters Patent, No. T6l,290, and to a shuttle of the type employed in said loom, said shuttle being designed to carry the weft-units into the shed in the manner set forth in said patent, but being in this case provided with additional parts and members,"whereby the new results are attained. v

T he primary object of my invention is to produce a shuttle, of the class mentioned above, which is capable, of handling successfully the slats which form the body of the fabric or shade, or the weft-units, even though such weft-units be very narrow and light in weight. l Vith this shuttle weft-. units of any width, even the narrowest, can be quickly, accurately and positively placed and deposited in the shed of the loom.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a side elevation, in partial section or partially broken away, of a shuttle which embodies a practical form of my invention; Fig. 2, a bottom plan of said shuttle; Fig 3, a crosssection taken on lines a ;c, looking in the direction of the associated arrow, in Fig. 1, and, Fig. i, an end ele- Specification of Letters Patent.

vation of said shuttle, the foremost parts of the same being in cross-section.

Like parts throughout the several views are designated by like numerals of reference.

Although I have illustrated and will presently describe in detail a practical form of my invention, I do not desire or intend to be thereby restricted unduly, since various modifications and changes in the shape, size, arrangement of parts, and details of construction may be made without departing from the nature or spirit of said invention.

Since the shuttle travels first in one direction and then in the other, carrying with it each time a weft-unit, the new elements are provided at both ends of said shuttle, but such elements at one end are duplicates of those at the other end and entirely independent thereof.

In the first view a portion of the body of the shuttle at the right-hand end is broken away to disclose fully the mechanism provided at such end.

The shuttle, shown in the drawings, comprises a body 1 having a bottom plate 2 with terminal projections or extensions 3-3, and provided at the ends underneath with gripping members, for the weft-units, con sisting of resilient aws and 55. The body 1 is designed to travel in the raceway of a loom, and the plate 2 is provided adjacent to its longitudinal edges with shoes 66 that are adapted to slide on the raceway track. Each pair of jaws 4E and 5 is located beneath one ofthe' extensions 3, and the jaws in each pair are designed to have one end of a weft-unit, such as is shown at 7, in Fig. 1, forced between them, and firmly to grip and hold said unit and to carry it into the shed of the loom, when the shuttle is shot. Each of the jaws 5 is secured to a lug 8 that extends downwardly from the bottom of the plate 2, while the jaws 4 are formed by the terminals of a resilient strip 9 secured to a central lug 10 that also depends from said plate bottom. The parts thus far described arevsimilar to corresponding parts set forth in the hereinbefore-mentioned patent.

In each end of the shuttle body 1 is a slot 11, and pivotally mounted at 12 within said slot is a releaser and projector 13 for the weft-units, Each releaser and projecfrom the associated roll 23 at the time the shuttle carries said releaser and projector into position to deposit a weft-unit, such amount of movement being also sufficient to open fully the jaws 4 and 5, with which said finger is in engagement, and positively to.

thrust the weft-unit, held by said jaws, downward with the desired force.

The springs 18 must, of course, be sufliciently strong to raise the releasers and projectors 13 and draw their finger extremities from between the jaws 4L and 5, as soon as the work of liberating the weft-units is finished in each instance.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. A shuttle, of the class described, provided with holding means for weft-units, and further provided with means for forcing such units from such holding means.

2. A shuttle, of the class described, provided with holding means for weft-units, and further provided with means for forcing such units from above from such holdin means.

A shuttle, of the class described, provided with separable holding means for weft-units, and further provided with means for separating said holding means and enl gaging such units to release and positively eject the latter.

4. A shuttle, of the class described, provided with separable holding means for weft-units, and further provided with means for separating said holding means and projecting a weftunit therefrom.

5. A shuttle, of the class described, provided with resilient separable holding means for weft-units, and further provided with means for forcibly ejecting such units from such holding means.

6. The combination, in a shuttle, with a body provided with weft-unit-gripping jaws, of a movable member carried by said body, and having a part which is brought into operative relation to a weft-unit held by said jaws to eject the same.

7. The combination, in a shuttle, with a body provided with weft-unit-gripping jaws, of a movable member carried by said body, and having a part which is in operative relation to said jaws and to a weftunit held thereby, and adapted positively to eject such weft-unit.

8. A shuttle comprising a body provided with weft-unit-gripping jaws, and a springpressed member carried by said body, such member having a weft-unit-liberating and ejecting part, and also having an actuating art.

9. A shuttle comprising a body provided with two pairs of weft-unit-gripping jaws, and a pair of members carried by said body, such members having weft-unit-liberating parts, and also having actuating parts, which latter are in different planes.
