Application filed March 13, 1916. Serial No. 83,761.

To aZZ whom it may concern:

Be it known that 1, Virus): C. FISHER, a citizen or the United States, residing at Middletown. in the county of, Middlesexand State of Connecticut, have invented a new and useful Improvement in Machine Gun Caitridge-Conveyers; and i do hereby declare the. following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application and represent, in

Figure 1 a broken view in side elevation of a niachine un cartridge-conveyer constructed in accordance with my invention, showing three cartridges therein. Fig. 2 a viei' of the belt in vertical transverse see- Fig. 3 a

schematic transverse section of one of the two strips of woven fabric used in the production of the conveyor.

My invention relates to an improvement in the belt-likecartridge-conveyers designed for use in conveying cartridges through the firing-chamber of a rapid-fire machine-gun, the object being to reduce the cost of producing such conveyers to the minimum, as well to produce an eliicient, convenient and durable article.

With these ends in View, my lflYEIliilOIl consists in a machine-gun cartridge-con veyer having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ two corresponding strips Of' l\()\'11 fabric 2. 3, placed face to face and fastenedtogether by metal clamps 4 secured in place by eyelets 5, the said clamps a being regularly spaced apart at the distance required for producing pockets 6 for the reception of cartridges 7. To adapt the conveyor to grip'the shouldered, bullet ends of the cartridges, the lower edges of the strips 2, 3, are thickened as at 2 and 8 so as to-contract or reduce in the lower ends of the cartridgediamcter pockets 6. F or this purpose, the

loom used in producing the woven strips 2 and 3, i. set to weave a strictly single ply fabric 01 warp threads 8 and weft threads 9, and also set to change the Weave at the point wh re it is desired" to begin to thicken the lower portion of the strips so that al, though the weave is continued as a single ply weave, extra warp threads are'introduced and interwoven so as to materially thicken the lower portions of the strips, the extra warp threads so introduced being other words, the loom is set so as to produce a single ply fabric, in which the weave is changed, as for instance, to a twill weave which permits the introduction of. an excess of warp threads throughout that portion of the fabric which it is designed to thicken. The fabric thus produced is a combination of plain weaving and twill weaving, but retains its characteristic as a single-ply fabric. The loom is also set to produce the familiar tubular or'corded edge well known in the art and illustrated in Fig. 3 by the loop 11 filled with cords 12.

illustrated in Fig. 3 by the threads 10. In

from plain weaving to weaving of another type of weaving, larger warp threads may he introduced and interwoven in addition 7 to the standard warp threads used in the plain woven portions of the fabric. But, however, the thickening of the lower portions of the strips is effected for the purpose stated, the weaving of the entire width of the strip will be characterized as a single-ply weaving. In any event the additional threads will be themselves actually interwoven into the fabric.

By weaving the strips on the single-ply plan, I am enabled to operate the loom and produce the woven strips in half the time in which they can be produced if they are woven on the double or two-ply plan, this rule holding true if the number of plies is increased. Thus a single-ply strip can be produced in one third of the time that would be. required for a three-ply strip and so on. I am therefore enabled by my invention to effect a great economy of time and labor in the manufacture of the thickened strips, as well as a substantial economy of thread. i

I claim 1. A woven machine-gun cartridge-conveyer consisting of two woven strips placed face to face and secured together at regular intervals to form cartridge-receiving pockets, the said strips being woven as singleply strips having their lower portions changed in Weave for the introduction of interwoven additional threads to thicken them, whereby the lower portions of the cartridge-receiving pockets are reduced in diameter and the pockets thus conformed to the shoulder-portions=of the cartridges.

2. A woven machine-gun cartridge-conveyer composed of two woven strips placed face to face and attached together at regu- 10 lar intervals to form cartridge-receiving,

pockets, the said strips being Woven as single-ply strips having their lower portions changed from plain weaving to twill Weaving to permit the introduction of interwoven additional warp threads to thicken them, whereby the lower portions of the cartridge-receiving pockets are reduced in diameter and the pockets thus conformed to the shoulder-portions of the cartridges.

WILLIAM C. FISHER.
