Patented July l2, i910.

pplcation filed October 27, 1909. Serial No. 524,857.

To all whom 'it may concern:

' Bc it known that l, Go'r'rnon ELonnLn, a citizen of the United States, residing in the city of New York, bprough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful lmproveinent in Cartridges, of which the following is a specification.

The invention relates to fixed ammunition for firearms, and the main object of the iiivcntion is to provide a construction which. the shock of recoil is lessened, thus permitting charges of greater efliciency to be safely employed.

Another important object is to provide a sealed or completely closed base with space ,for the fulminate gases to expand harmlessly at the instant of explosion and thus lesson the danger due to the escape of such gases rearwardly through the base of the shell, and permit with safety the use of large fulminate charges insuring certainty of lire. Y

The invention consists in certain novel features, and details of construction and arrangement by which the above objects are attained, to be hereinafter described.

The accompanying drawings form a partv of this spccilication and show approved forms of the invention. A

Figure l is an axial section through the rear portion of a paper shell adapted for use in a shotgun. Fig. 2 is a viewof the rear face thereof. Fig. 3 is a transverse section of the same showing' the interior portions in elevation. Fig. d is a view of the rear face of the base-block. AFig. 5 is a corresponding` view of the front face. Fig. (3 is a. side elevation of the same base-block. Fig. 7 is an end view of the primer. Fig. 8 is a similar view of the anvil. Fig. 9 is a side view of the powder-cup or recoil absorber. Fig. l() is an axial section through the rear portion of a metallic shell cartridge showing a modified forni of the invention. Fig. ll is a view of the rear face of the. basc-blocl thorefor. Fig. l2 is an axial section through a base-block and attached powder-cup, showing anotlwr niodilication.

Similar letters lof reference indicato like parts .in all the ligures.

Referring lto Figs. l to 9 inclusive, showing .the invention as applied to a paper shotshell, A is the metallic base, l the paper tube received therein and flanged inwardly at Bl telic against the inner face of the the thickness of the flange B1 thus provid- A ing an annular space Z) for the expansion of fulminatc gases, which space is increased by the annular channel c2 in the rear ,face of the base-block.

D is a cup of sheet metal, cylindrical at the forward open' end D1 which matches y closely within the paper tube B, and tapered slightly to the bottom D2 and rovided with longitudinal lcori-uga.tions 3 extending from the bottoni to the cylindrical portion at the front. The bottom is perforated cen- 'trallyto match to the opening c in the basebloclr and is secured to the latter upon the boss C1 by expanding and curling the` forward end El of the primertube upon the inner face of the bottom D2 as at E2.

The primer-tube E is of metal slightly tapered and is received in the counterbore c1 of the base-block, the eXtensionE1 is of less diameter and forms an annular shoulder or offset lying upon the shoulder or rabbet C3. The rear end of the tube E is curled outwardly at t3 upon the nipple C2 and thus serves with the flange E2 as a hollow rivet firmly joining the cup D to the base-block C.

lNithin the primer-tube is an anvil F having lire openings f therethrough, and a primer G carrying fulminate g presented to the anvil. The rear face of the primer lies against the inner face of the metallic base A in position to be struck and forced forward by the action of the ring-pin of the gun against the sealed base.

The primer (i is a small cylindrical or ,slightly tapered block having acavity in its front face, .shown as an annular V-shaped channel, and the anvil F is a similar block having an angular spur, shown as a sharp annular ridge F1, adapted to induce the required friction with the fulminate when the latter is forced forward bythe impact of the tiring-pin upon the base of they shell, the

lire passing through the openings f in the anvil to ignite the powder' charge.

esami The forward movement of the conical primer in the tapered primer-tube tends to tightly seal or plug the latter against the escape of fulminate gases rearwardly, but iii the event of such escape past the primer the gases may expand liarinlessly iii the space b c2 without danger of bursting the closed metal base A.

The charge of oivder is received in the cup D, held therein by the Wad Il, and on exploding performs its function as usual, but the initial rearward shock due to the eX- plosioii is lessened by the expansion of the corrugations l)3 into the surrounding space' within the cartridge, thus reducing the recoil of thevgun for a given charge of powder, or, correlatively, permitting the use of ay larger or heavier charge.

Fig. l0 shows a metallic cartridge iii .which the powder-cup D* is more sharply tapered and isjoined to the base-block C* by spreading therein a flange C5 formed directly on the front face of the block. In this cartridge the anvil F2 is formed integral with the base-block and receives the primer G2, the primer-tube being omitted.

In tlie't'orin shown iii Fig, 12 the powdercup D5 is simply joined to the base-block (1 and the latter is boredx and counterbored to receive the anvil F3 and primer G3 Without employing fa. primer-tube.

Either the'ipigiiner or anvil .may receive the charge of iuhninate, or both may be 'charged as indicated in Fig/12.

Other modifications may be made in the forms and proportions of the parts within wide limits without departing from the invention, and parts may be used withoutthe whole. rl`he powder-cup may be variously formed to provide the required expansibility, and be secured in place in any approved manner, and the charge therein fired by any suitable primer and lii'ing means.

The cup shown in Fig. 1 is designed for service willi a noi-mal charge oli bulk powder` of *any standard malte, the sharply tapered-forni shown in Figs. l() and 12 is intended to serve with dense powders; in all cases the air imprisoned in the spaces between the exteriorl of the expansible cup and interior of the shell serves as an air cushion to absorb the shock of recoil, and such spaces should be proportioned to the quantity and character of the powder used in charging the shell.

1. In a cartridge, a base and shell, an cxpinsiblo cup located adi'acenty to said base and within said shell and adapted to expand with the explosion of a charge ot powder v received in saidcup.

i2. In a cartridge, a base and shell, a conical cup locatedadjacent t'o said base andivithin said shell and adapted to expand with the explosion of a charge of powder received in said cup.

3. ln a cartridge, a base and shell, a corrugated cup located adjacent to said base and within said shell and adapted to expand with the explosion of a charge ot powder received in said cup.

4. In a cartridge, a base and shell, a corrugated cup secured to said base and having a cylindrical open end matching the interior ol said shell and adapted to expand with lthe explosion of a charge of powder received i'n said cup. v

In a cartridge, a base and shell, aconical cup secured to said base, having loiigitudinal corrugations, and a cylindrical open end matching the interior of said shell, 'and adapted to expand` with the explosion of a charge of powder received in said cup.

lso

G. In a cartridge, a closed base, a baseture in its'bottom, a primer-tube extending through said opening and apeitureand se curing said cup to said base-blo'clgtanda primer and anvil 1n said tube, all arranged to serve with the base and shell of a car` tridge.

9. In a cartridge, a closed base, a shell, a base-block located within said shell and ad- `jacent to said base and having an opening therethrough, a powder-cup having a bot.-

toni, a cylindrical open end matching the in tcrior of said shell and corrugations between said 4cylindrical end and bottom, a primertube extending. through said opening andiA said bottom and securing said-cu base-block, and a primer and anvil in said tube.
