. Specification of LetitQrsP-atent.

Patented Dec. 1'7, 191.8.

Application filed May 14, 1918. Serial No. 234,542.

To all whom it may concern:

Be it known that I, EDWIN BALL STIMP- son, a citizen of the United States,-residing Brooklyn, county of'Kings, andstate of New York, have invented certain-new a r d useful improvements in Cartridge-Belts, of which thefollowing is a specification.

My invention relates to-cartridgefeed1ng belts of the type used in rapid fire machine guns, and has for its object to provide an improved belt formed of .unsubstantial sheet material having reinforcing tensile members embedded therein.

In an application-for,;patent,-Ser. No.

filed byme on *May19, 1'9118,a cartridge belt of this general type wasshown and described which consisted of two strips of light and unsubstantial sheet material, such s paper, reinforced alongfthe center and at either edge with a cord or thread'designed to increase the tensile strength of thebelt as a whole. The two strips making up thebelt were preferably attached to-each other by stitching together spacedaportions of the threaded portions at suitable inten vals to form cartrid e holding loops. "This form it of cartridge be t is highly satisfactory and serviceable, but as I have continued-my experiments, T have developed another arrangement ofgthe reinforcing threads and so utilized the new arrangementi that an improved manner for forming the cartridge holding loops has resulted and consequently a generally improved form of :belt of this a general nature has been obtained.

The principal feature of the inventionresides in the formation of a belt by meansof two superposed strips of material such as paper, each strip having a plurality of reinforcing cords spaced apart andembedded therein along each lateral edge thereof, together with means for attaching the strips to each other at points between the adjacent reinforcing cords, to form suitable cartridge holding loops.

Other features of the invention will be hereinafter described.

In the drawings,

Figure 1 is a view of a section of cartridge belt 3 embodying a preferred form of the invention and showing a number of cartridges in place therein. 1

Fig. 2 is a view similar to Fig. 1 and showmg a modified form of means for at taching the belt strips together.

Fig. 3 is a view of a section of belt show mg the use of metallic clips for clamping the strips together to form the .belt.

Fig. l-,is a view showing the use of an ordinary form of staple with which the strips are attached together. 7

Fig. 5 is an enlarged sectional view showing'the folded paper strips used to make up ,tlie belt.

' The cartridge feeding belt shown in the drawing comprises the strips 1 and 2 formed of double strips of material such as paper or the'like, having two sets of reinforcing cords '3 and 4 embedded therein in two slightly spaced apart positions along each lateral margin of the strips. The reinforcing .cords'3-and 4: are preferably of such a nature as to offer a very substantial resistancegto breaking, so that they add in an important degree to the tensile strength of the belt as a Whole.

The belt forming strips are preferably attached 'toeach f other at suitably separated points .to' form cartridge holding loops by means of metallic fastening members taking various'forms. llhave found eyelets 5, such as are shown in Fig. 1,,to be well suited to the purpose inyicw, and by placing them in oppositelydisposed positions between the parallel reinforcing cords 8 and 4, near each lateral edge, any tendency that the material might otherwise have to tear as it is'bent over "the e'dge, ofthe eyelet is eliminated, since the tensionon the strip orweb is taken up byi'the reinforcing cords. This makes a very effective construction and the eyelets can be rapidly fastened inrplace in making up the belts. It will be seen that the eyelet members 5 are wider near one margin of thebelt than the other so as to form holding loops of different size to fit the correspondingly different diameters 6 and 7 of the car fridges.

It will be seen that by placing the reinforcing cords in groups, and preferably in pairs, and making use of fastening members that exert their clamping effect on substantially theen'tire width of the material between'the cordsin each pair,the cords are held in immovable relation with respect to eachother and one cord cannot be pulled to a more advanced point than another.

This has a very important result in that any tendency which the belt may otherwise have had to yield in such a way as to allow one edge to be pulled to a position in advance of the other and thus destroy the precise 7 right angled position of the cartridge to the longitudinal axis of the belt, is efi'ectuallyof paper having a plurality of reinforcing eliminated.

While eyelet fastening means applied in the manner indicated in Fig. 1 are the preferred form of construction, itis possible to utilize other ways of attaching the strips together and secure the "advantages to be had by grouping a plurality of cords along each margin ofthe'belt strips. 7, in Fig. '3 of the drawing 1 have shown the use of-eyelet members 5 placed in such position with relation to the reinforcing cords that the flanges of the eyelets overlap the cords on either side and thus provide a very secure and effective construction. L

Still another form of fastening means that is well adapted to the purpose is shown in Fig. 3 of the drawing in the form of clip members 8 which are bent into place from opposite'edges of the strips and; are sufil ciently long to extend across bothadjacent threads in the manner indicated. ln'l ig. 4 of the drawing the use of staples 9. is

' shown and it will be seen that in each form of the invention ordinary andwell known forms of metallic paper fastening devices are made use of to attach the belt "strips fto-' gether to provide a belt structuresuiflciently well reinforced by the reinforcing cords to withstand any strain to which it is likely to be subjected; to ri idly hold the cars tridges'in the proper position for feeding;

and, at the same time, provide a construction that is much lighter, takes up less space, and isa great deal less expensive than cartrige belt constructions now known and used. V v
