Application filed November 25, 1912.

To all whom t may concern:

Be it known that I, ROBERT Gr. CLYNE, a subject of the King of Great Britain, residing at Alton, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Cartridges, of which the following is a specification.

My invention relates to improvements in cartridges, and more particularly to that class or t-ype known as paper shot shells, the primary object of the invention being to pro-vide a generally improved cartridge of this class of exceedingly simple construction which will be cheap of manufacture, and eflicient in use.

A further object is to provide a generally improved reinforced metallic base c ap provided at its mouth or rim portion with an inwardly extending beading forming an interlocking or anchor member and preventing the tubular paper shell from being forced out of the cap at the time of tiring, and also forming a battle between the mouth of the cap and the tubular shell portion thereby preventing the escape of gases between these parts, and likewise forming a subjacent annular interlocking anchor or baflie between the subjacent portions of the shell and the base wad, thereby preventing` the blowing out or disarrangement of these parts during firing and likewise preventing the escape of gases between the base wad and the tube.

A still further object is to reduce the cost of manufacturing the metallic base cap as compared with the ordinary form of base cap known as the trimmed or chamfered cap in which the chamfering or trimming is performed in a machine using a knife to bevel the mouth or upper edge of the cap about the inner periphery thereof so that the cap will readily slip over the tube during the operation of assembling, and which chamfering or beveling process is notonly eX- pensive but frequently results in imperfect caps due to dull tools and irregular.` alinement in the holding of the cap during the chamfering or trimming operation.

A still further object is to provide an improved metallic base cap having a smooth reinforced or non-eXpansible mouth or rim which will prevent the breaking or splitting of the cylindrical side walls of the cap during the operation of assembling when the Specification of Letters Patent.

Serial No. 733,276.

base wad and shell are forced into position or when the cartridge is tired.

lVith the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure l, is a side elevation of a cartridge constructed in accordance with my invention, a portion of the cap end being broken away for the purpose of clearer illustration of the parts. Fig. 2, a perspective view, partly in section, of a slightly modified form of the improved metallic base cap. Fig. 3, a similar view of a further modified form of same. Fig. 4f, a plan view of the form shown in Fig. 3.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved cartridge comprisesa paper shell or tube 1, to which is secured the irnproved metallic base cap 2, and an inserted base wad 3, in the improved manner hereinafter referred to. The improved metallic base cap 2, is provided with the usual peripheral flange 2, for holding the cartridge in position within the breech of the gun barrel, while the base or bottom of the base cap may be provided wit-h a battery cup receiving opening or primer pocket 2b, as may be desired, for the reception of a battery cup or primer of any suitable and convenient form.

As a means for reinforcing the mouth or rim portion of the base cap 2, as well as providing a combined anchor and baffle member for interlocking with vthe paper shell or tube l, as well as preventing the escape of gases between adjacent parts'or the disarrangement of such parts during ring or the eX- plosion of the combustible charge, the upper marginal edges of the base cap are curled or beaded inwardly forming a reinforcing anchor beading and baflie member 2", which beading projects inwardly about the inner periphery'of the cylindrical side walls of the cap and forms a'smooth round edge at the mouth of the cap for the purposes above mentioned and hereinafter more fully eX- plained.

After the shell l, and base cap 2, are assembled in proper position, the base wad 3, it of the type herein shown, may be in-v serted and pressed home andduring the operationv of pressing the base wad into proper position the reinforcing anchor beading andr baille member 2, at the mouth of the cap will be causedv to embed itself into the subjacent or contiguous portions of the shell or tube thereby forming an annular interlocking rib or balle portionv la, inthe shell or tube l, and likewise an annular recess portion 3a, in the subjacent or contiguous portions of the base wad thereby securingly interlocking the parts together vas against disarrangenient or the escape of the gases or products of combustion during the firing of the shell. It will also be observed that the reinforcing anchorv beading and battle member 2, forms a smooth non-expansible mouth iorthe base cap which prevents the splitting of the side walls of the latter when the base wad is forced into position or during the liring of thecartridge or shell as sometimes occurs with the ordinary form of cartridge and metallic base cap now in use. The base wad 3, is preferably, though not necessarily, ein tended upwardly within the shell l, beyond the plane of the inouth or reinforced portion 2, of the base cap and may bev provided with a large receptacle vor opening 3b, terminatving ina small centrally located opening or passage 3c, leading to the ordinary 'batteryv cup mounted within the receiving opening or receptacle 2b, of the base cap.

In Figs. 3, and 4, I have shown a slightly modified forni of reinforcing anchor beading and battle member, in which instance the upper marginal edges of the cylindrical side walls of the base cap are crimped or crenated into a scalloped beading or vbattle member having the ribbed portions cf, and depressed or indented portions Z) arranged at substantially regular intervals, and which scalloped or serrated beading is adapted to interlock with the subjacent shell for the purpose of preventing any circumferential movement between these parts.

From they vforegoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood. f

Having thus described some of the embodiments of my invention, what I claim and ydesire to secure by Letters Patent is# l. In a paper shell cartridge, a metallic base cap having its edges curled into a scalloped inwardly curled anchor beading.

2. In a paper shell cartridge, a metallic base cap provided with va battery cup receivingvreceptacle and a peripheral flange and having the upper marginal edges of its vcylindrical side walls curled into an annular anchor beading and baille member.

it cartridge, comprising a tubular inembei' provided with an annular recess and an interlocking rib or baille portion, a base Wad provided withv an annular recess portion in interlocking engagement with said interlockv ing rib or baille portion, and a metallic base cap provided at its inout-h with an inwardly extending annular beading seated in said annular recess of said tubular member.

In testimony whereof I have ailiXed my signature in presence of two witnesses.
