PRIMING DEVICE FOR CATHTRIDGES'AND SHELLS I No. 838,493.

"1 To all who)! it ngy concern:

Be it. known that I, CHARLES A. BAILEY. a citizen of the United States. residing at Cromwell, in the county of Middlcscx and 5 State of Connecticut, have invented a Priming Device for Cartridges and Shells, of which the following is a s )ccitication'.

The primary object o my invention is to In the usual form of center-fire cart ridges,

t 5 employing a winter or cap fitted in the hole in the head of the cartridge, it often happens that the gas generated by the explosion of the powder charge forces its way out through the breech by passing around such cap or :0 primer. Therefore, to entirely remove the possibility of any escape of gas at this point I rovide the firing-cap or primer with a bushmg of soft material, which is adapted to fit the opening in the cartridge closely, and betng soft or yielding it will, when the cartridge is exploded, expand to more etl'ectually close the joint between said bushing and cart ridge, as well as the joint between the bushing and primer.

In the following specification I have fully described my invention, and wit at I claim as new, and desire to fully protect by Letters Patent, is more specifically set forth in the ap )ended claims.

in the accompanying drawings. which form a part of this specification. Figure 1 is a view illustrating the application of my invention to a cartridge or shell having a comparatively thick head. Fig. 2 is an enlarged detail side 0 elevation of the priming device. Fig 3 is a sectional viewtizereof. Fig.4 i a view showing a modification of the invention, in which he bushing is upset at opposite sides of the head of the cart ridge.

In carrying out my invention I employ a bushing or battery-cup A of soft metal, in the outer end of which is a recess or cavity a to receive the primer or tiring-cap l3. and from said cavity here extends through the bushing to the inner end thereof a small opening a, through which the flash or flame front the primer passes into the cart ridge. The recess or cavity a is of a shape to correspond with Specification of Letters Patent. ig plimtion filed 1m 26, 1905. Serial No. 267.086-

Patented Dec. 11, 1906.

i that/of the printer or firing-cap, and in some i instances, therefore, it is countersunk atits outer end, as at a into whiehthe rim of the primer or firingcap is seated. Of course in case a-s'traight primer is employed aplain cavity would be formed in the bushing.

The outer end of the bushing or batterycup A is flared or )rovided with a circumferential flange a adapted to seat in a. countersunk portion of an opening or hole through the head of the cartridge.

the drawings) is of the usual construction, and the head or end wall 0 thererof is provided with an opening 0' large enough to receive the body of the bushing or battery-cup A, and such opening is countclsunk -or ta- 7o pered, as at 0, into which the flared of flanged portion a of said bushing or battery-cup is seated to hold the same and prevent it from being forced into the cartridge when the primer is struck by the firing-pin. It will be here noted that as shown the outer end of the bushing or battery-cup is shown as provided with a flange adapted to seat in the countersunk port ion of the hole in tle cartridge.

The bushing being of comparatively soft metal will not only closel Y embrace the primer or firing-cap (I11l)((l( ed therein, but will also closely fit, the openingdn the head of the cartridge and will be retained in the latter by frictional contact.

In some instances, as shown in Fig. 4, I purpose to more firmly connect the bushing or )attery-cup, as I), to the cartridgeby upsetting a flange, as'd, against the inner side of the head of the cartridge, such flange being 0 opposed to the flange (1' on the outer side, and of course this form may be used in connecting an inner reinforcing-piece to the head.

The inner end of the flash-opening a, through the bushing or battery-cup is preferably contracted or closed, as shown, so as to prevent any powder from entering the primer when loadmg the cartridge.

the soft bushing A and firing-cap B, may be marketed as a separate article of manufacture, as in the case of the ordinary primers, and can be readily applied by simply forcing the same the metal head of the cartridge. Vhen ap- The cart ridge or shell (designated as C in 65 My improved printing de ice, comprising into the countersunk or tapered oiening in plied as illustrated in Fig. 4, a suitable tool is emploved to upset the flan e (1 against the with such a priming device the latter can be readily and conveniently removed.

The bushing is preferably made of soft metal, such as a lead alloy.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cartridge, the combination with the shell having an opening through the head, of a soft-metal bushing fitting snugly within the opening and having flanges upset against the inner and outer sides of the head,

said bushing also having an elongated tapcred body portion projecting within the shell. a shallow cavity in its outer end. and a flash-hole extending through the body from said'cavity to the inner end of the bushing at which latter point. it is closed bya thin wall;

together with a priming-cap frictionally engaging the cavity of the bushing, as herein shown and described.

2. As a new article of manufacture, a priming device for cartrid es and shells comprising an elongated conical-shaped soft-metal bushing having an exterior flange, a cavity in its base, and a small flash hole or pas age extending from the inner end of said cavity to ar the point of the bushing at which latter lint it is closed by a thin wall anda priming-eap frietionally engaging the cavity, as herein shown and described.

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

CHAS. A. BAILEY.
