SHUTTLE.

Application filed April 18,

This invention relates to improvements in shuttles, and the principal ob ect of the invention is to generally improve the construction of the shuttle in that part which supports the cover member, as hereinafter specifically set forth.

In the attached drawings:

Figure l is a plan view of a shuttle made in accordance with my invention;

Fig. 2 is a longitudinal section on the line 2-2, Fig. 1; and

Fig. 3 is a transverse section on the hue 33, Fig. 1.

Referring to the drawings, the shuttle may comprise the usual hollow body 1 having pivotally secured at one end a cover member 2 adapted to close eifectively the open side of the shuttle. When closed, the cover member 2 rests at a point adjacent its free end upon a transverse pin 3, and by slightly flexing the cover about this pin, the extremity, which is flanged outwardly, may be inserted under a pivoted hook or clamping element which holds the cover 1n the closed position.

Instead of forming the cover support 3 in the usual manner by passing a pin transversely through the shuttle walls, I make this support in the form of a staple whose ends extend downwardly in suitably formed openings 5 in the shuttle sides, as clearly illustrated in Fig. These openings are located well within the planes defined by the outer surfaces of the shuttle so that the up per edges of the shuttle walls, except for the slight recesses 6 in the inner edges providing passages for the staple, are continuous. The staple is firmly driven and in operation displacement is positively prevented by the cover.

Heretofore, it has been customary to support the cover by a pin driven transversely through thesides of the shuttle. This resulted in apertures extending through both walls, one to admit the pin and the other to give access to the end of the pin for driving it out of the shuttle, as is sometimes nec essary. These apertures in the outer walls. of the shuttle are in themselves undesirable, and in driving the pins into place there is 1928. Serial No. 270,931.

an unavoidable tendency to split the shuttle. The greatest fault of the prior device resided in the fact that the normal wearing of the upper edge of the shuttle eventually exposed the cover supporting pin and resulted in the formation of sharp edges or corners which caught the warps as the shuttle moved through the shed thereby effecting considerable damage. These pins also sometimes work loose and, projecting beyond the surface of the shuttle, cause damage to the loom or the weaving.

Many and substantial advantages accrue to my construction. By the present'invention, the continuous and smooth upper edges of the shuttle are preserved regardless of the extent to which the shuttle may be worn away, thereby avoiding damage to the warps and insuring a maximum useful life for the shuttle. Apertures in the outer walls of the shuttle are avoided, and due to the fact that the staple has no tendency to split the wood of the shuttle a considerable economy in manufacture is eifected. The staple applied as described actually reinforces and strengthens the shuttle. Also, the staple cannot work loose being retained positively by the cover.

I claim:

1. A shuttle comprising a hollow body, an adjustable cover member, a clamp for holding the cover in closed position, and a support for the cover in the closed position, said support being mounted in the body independently of the cover and being positively retained in the body by the cover when the latter is clamped.

2. A shuttle comprising a hollow body,

an adjustable cover member, a clamp for holding the cover in closed position, and a support for the closed cover comprising a staple driven into the body and positively prevented from displacement by the clamped cover.

8. A shuttle comprising a hollow body having bottom and side walls and an open top, a cover adjustable to close said top, and a staple mounted in openings extending downwardly in the upper edges of the side walls entirely within the outer side surfaces of the shuttle and constituting a support for the closed cover.

4. A shuttle comprising a hollow body having bottom and side walls and an open top, and said side walls having recesses extending downwardly from the upper edges,

a supporting member independent of the cover extending transversely across the interior of the shuttle and having parts extending into said recesses, a cover adapted to close the openside' of the said body and finding a seat upon said transverse member, and means for holding the cover against the seat.
