SPECIFICATION forming part-of Letters Patent No. 236,23Q,da.ted fl 'a1iuary4, 1881.

' Application filed November 18, 1880. (No model.) 1

To all whom it may concern.-

Y Be it known that I, HARRY KING, a citizen of the United States, residing in the city of Washington, and District of Columbia, have invented certain new and useful I mprovemen ts in Cartridges; and I do hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it a'ppertains to make and usethe same, reference beinghad to the aca part of-this'specification.

My invention relates to center-fire metalllc cartridge-cases for breech-loadin g fire-arms, 1n

' which the percussioireap is received in a recess in the head and exploded upon an anvil contained .in the recess.

-Its object is to facilitate the insertion and disengagement of the cap. I accomplish this result b Y the mechanism illustrated in the ac companying drawings, in which- Figure 1 is a perspective of the cartridge primed; Fig. 2, a perspective of :the cartridge, 'e iection of the exploded. cap being represented ig. 3, a longitudinal section through the head or the cartridge-case on line a: w of Fig. 7, the guide 0 being retracted and closed upon the cap, and holding it upon the anvil. Fig. 4 is the same section as Fig. 3, showing the guide 0 open, protruding, and ejecting the cap. Fig.

V 5 is a front view of the head of the case, show ing the slotted recess, the guide (3 and the anvil havingbeen removed. Fig. 6 is a'front view of the head of the case, showing the slotted recess and anvil, the guide 0 not being shown. Fig. 7 is a front viewof the head of the case, showing guide'O and anvil in place. Fig. 8 is a side view of the guide 0. with a part in section, the guide being represented open, and supporting, but not grasping, the' cap. Fig. 9 is a plan ofthe blank from which the guide 0 may be formed. Fig. 10 is a perspective of the anvil.

Similar letters referto similar parts through.- out the several views. A is a cylindrical metallic cartridge-case. The head of the case A has an exterior central cylindrical recess, 13, having in the bottom an oblongrectangular cen tral slot, 1). r

The anv1l,-whicl1 is shown in Fig. 10, is apress against the anvil when block of metal, consistingof the perpendicular post D, shaped to enter the cap, and its ob--' to the charge; and the top of the base D is also beveled to make room within the recess for the projections 01 of the guide 0. i

G is a spring guide and carrier for the'percussion-cap. It consists of an oblong metallic" plate-spring, bent at the middle,'and having at each end a semicircular jawor half-ring,

0, opposite and corresponding to each other. When the spring-guide (J is'closed the halfrings a a form a'cylinder adapted to fit snugly in the recess B and surround and closely grasp a cylindrical percussion-cap, 11, making gastight joints.

Below the jaws theshafts of t-he springguide'O are provided with the rigid projections d, two on each shaft. The projections are toward a common center, and their points constitute a horizontal platform for the cap. Their lower edges are sloped upward to fit over the anvil-base DJ;

The blank from which the guide 0 may be formed (see'Fig. 9) shows its shape when flat tened out.

The shafts e eof the guide 0 are adapted to slide and be guided in the slot 1). They do not primed. Thus room, as shown is left for the flash of the the charge.

In the order of construction the guide 0 is first inserted in the recess B and the bend of the shafts 6 passed through the slot 12. The anvil is afterward introduced into the recess B and placed between the shafts c crosswise, and over the slot I), as described.

In operating my invention the spring-guide 0 is protruded from the recess B by longitudinal pressure either with the finger or a stick, as shown in Fig. 4 in'dotted lines, upon. the bend ofthe spring, the guide 0 being prevented bythe anvil, which lies within its bend, from being in Figs. 3 and 7, fulmi'nate to pass to from within the cartridge-case,-

the cartridge is pushed entirely out. As the guide 0 protrudes the jaws c c are pressed apart by the operation of the spring and the pressure of the anvil against the inside of the shafts e c. The position of these parts at this stage is shown in Fig. 4. The cap a is then dropped within the jaws 0 upon the supports (1, where it rests loosely, as shown in Fig. 8. Pressure being.

. cap is removed in the following manner: The

spring-guide G is protruded by pressure applied within the case, as described. The cap is raised from the anvil by and upon the ejectors d of the guide 0 as the jaws c c recede from .each other and release their hold upon the cap. The cap is then tossed out, as shown in Figs. 2 and 4.

, The device for carrying and holding the cap is applicable to caps which have anvilsattached to them. In that case the post of the anvil D D is omitted, and the base or cross-piece D only is used, operating as a-stop.

Arms pivoted together at their lower ends may be used, instead of a bent spring, to unite the jaws of the guide 0. I

,The cylindrical shape is given to the jaws of the guide 0, both without and within, in

order to conform to the cylindrical shape 0 the cap and recess 13. When the cap or re cess has any other figure the shape of th' jaws must correspond. j

I claim as my invention, and desireto se cure by Letters Patent, the following:

1. In a cartridge, the recess B, having greater diameter than the cap, the space be tween the-cap and the walls of the recess be ing filledjby sliding jaws c a, by means 0 which the insertion of the cap is facilitated all as set forth.

2. In combination with a cartridge provider with the slotted recess B and stop D, th. semicircular jaws c c, terminating the arms 0, and adapted to embrace the percussion-cm within the recess, as described.

3. Ina cartridge, the combination, with a metallic cartridge-head having the recess] and the slot b, of the anvil D D, located a described, and the cap-carrying guide C, hav ing the semicircular jaws c c and the projec tions d, all as and for the purpose set forth.

4. In combination with a cartridge provider with the slotted recess B and anvil. D D, th semicircular jaws cc, terminating at bentsprin; and adapted to embrace the percussion-ca; within the recess, as described.

In testimony whereof I have aflixed m;

signature in presence of two witnesses.
