SPEGEFIGATION formingpart of- Letters Patent No. 226,932, dated April 27, 1880. Application ined Marte 1s, 1850. (no model.)

To all whom it may concern:

Be it known that GEORGE P. SALISBURY,

'I of New Haven, in the county of New Haven.

and State of Connecticut, have invented cer'- tain improvements in Paper Cartridge-Shells,

lo1 which the following is a specification.

llly invention relates to that class of cartridgeshells known as paper shells for use in shot-guns; andthe inyentionconsist-s in an improved method or process of construct ing the same, as hereinafter more fully described. Y

In the laccompanying; drawings, Figures 1, 2, 3, 4. and 5 represent thel various partsof which the shell is composed and the several stages through which they pass in the construction of theshell, while Fig. '6 shows' the shell completed, all the ligures except Fig. 3 representing central longitudinal 'sectiolis Heretofore this class ofcartridgeshells have lusually been made by'irst making the tube A, reenforce. B, and wad C of paper, and after assembling or putting these parts together, as represented in Fig. 4, then placing on the end a brass or copper cup, which was made without any ange, then putting the whole into a heading-machine 'and forming a flange on the metal head by pressing the 'wad with great. force, and thereby forcing the metal outward into the recess in the die.

.Another method which was patented, but,

so far as l am aware, never practiced, was to 'form the ange on the metal cup or head before applying it t0` the body, then cut a series of slits in the end of the tube or bodyA, so as to permit it to spread as it was `forced into the metal head, and then compress the wad inside to fasten the tube to the head.

1n making a shell by my plan, I prepare the tube A, re-enforce B, and wad C (if the latter be used, and which is optional) in the usual manner, and assemble them as shown in Fig. 4.' I then 'take the metal cup orhead-piece D and partially form 'la ange thereon, as shown in Fig. 3, where it will be seen that the projecting iiange a, while beingexpanded laterally to nearits full extent, is left open'in: side to a much greater extent than in the iinished head, the front side of the flange a being left inclined, as there shown.

After the head D, with its partially-formed ange, is put onto the body A, as shown in Fig. 5, the whole is subjected to the operation of a heading-machine, by which the inside punch first compresses the wad U endwise, thereby forcing the end of the tube A and reenforce B outward' all around into the open liange, after which, as the bunter descends, it forces the metal head D completely down, and thereby compresses the tlan ge a and com pletes it, at the same time clamping the endet' the tube A firmly between the two walls of the ange. as represented in Fig. 6, in which it will be seen that the front face of the flangeais made to assume a position at right angies tothe sides of the shell, or as near so as is usual in shells as ordinarily made.

By this. method otconstrueting the shell much less force is required than where the iiange is formed by pressing the metal outward by 4the compression of the wad, and consequently lighter machinery may be used, and by clamping the end of the tube rmly between the compressed walls of the flange the ,head D isso securely fastened to the body of ,the shell that it is impossible for it to becomel detached therefrom.

Having thus described my invention, what I claim is- As an improvement in theart of manufacturing paper cartridge-shells, rst `partially :forming a flange on the metal head, then placing said head with its open flange on the paper tube, and by compressing the wad fore-f ing the end ofthe tube outward into the cavity of the dan ge and clamping itthere by compressing the'ange upon it, as set forth.
