SPECIFICATIQN forming part of Letters Patent No. 4198,85?, dated June 6, 1.893. Application-filed December 19. 1892. Serial No. 455,562. (No model.)

To all whom it may concern.-

Beit known that I, CHARLES E. OVERBAUGH, of Bayonne, Hudson count-y, State of New Jersey, have invented anew and useful Improvement in Cartridge-Shells, of which the following is a specification.

This invention relates to cartridge shells having a paper body portion and a metal breech, and it consists in the construction and novel arrangement of parts as hereinafter set forth. One great objection to this class of shells is that .in extracting a shellfrom a gun the metal breech is apt to be pulled olf the paper body. My invention is intended to ob- Aviate this dijiiculty.

I will describe a cartridge shell embodying my improvement and then point outthe novel features in the claims.

Inthe accompanying drawings Figure l is a longitudinal section of a shell embodying my improvement. Fig. 2v is a longitudinal section of a paper body portion. Fig. 3 is a section of a portion of the metal breech and clamping jaw. Fig. 4 is abottom view thereof. Fig. 5 is a section of a portion of the metal breech as it appears before engaging with the other part of Ythe breech. Fig. .6 is a bottom View thereof.` Fig. is a bottom View of Fig. 2.

Referring by letter to the drawings A designates the paper body portion of the shell having an inwardly turned annular lip or flange a at its lower end.

B designates the outer portionof thebreech preferably of aluminum. It has a central opening and the Wall of said opening is beveled outward as shown at b. The breech portion B has an integral annular jaw portion l1 adapted to embrace the outer side of a portion of the body A.

C is the inner vportion of the metal breech, adapted to clamp the lip or ange a of the body A between the portions B, C of the breech. This portion C has an undercut portion c to engage over the inner-surface of the lip or flange a; an undercut portion cf toengage the inner surface of the portion B around the opening through it, and a hub portion c2 to pass through the opening in the portion B.

-Before the parts B, C are swaged together the hub c2 of the part C in all its parts has a circumference substantially Vequal to the smaller circumference of the opening through the part B, as shown in Figs. 5 and 6.

When the parts are placed together thehub portion o? is swaged outward by suitable tools, to engage the beveled wall of the opening through the part B of the breech, as shown in Fig. l. The dotted lines in Fig. 5, also show the form of the hub after being swaged.

Having described my invention, what I claim is l. In acartridge shell,the combination with or flange-of a metal breech portion having a jaw surrounding the body for a part of its length, and provided with a central beveled opening,-anda second metal breech portion having an outwardly swaged hub,-the lip or liange of the paper body being held between the two metalbreech portions,-substantially as set forth.

2. In acartridge shell, the combination with a paper body having an inwardly turned lip or hangar-of a metal breech portion conl nected to the body and having a central beveled opening,aud a second metal breech port-ion having the undercuts c and c', and the hub port-ion, all arranged substantially as set fort-h.

In testimony whereof I have signed my vname to this specification in the presence of ytwo subscribing witnesses.
