CARTRIDGE-SHELL CRIMPER.

SPECIFICATION forming part of Letters Patent No. 332,712, dated December 22, 1885.

Application filed August 17, 1885. Serial No. 174,618. (No model.)

To (LZZ whom it may concern:

Be it known that I, HENRY THOMAS HAZ- ARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful, Improvement in Implements for Crimping Paper Cartridge-Shells, of which the following is a specification, reference being had to the accompanying drawings.

In order to secure the wad that covers the shot and prevent it from getting loose and falling out in paper shell it becomes necessary to close the end of the shell by turning it in- This is usually accomplished by inserting the open end of the shell in a shallow circular groove out in the face of a disk and converging toward the bottom thereof, along which small knobs are mounted at intervals. By rotating the disk and pressing the shell firmly into the groove the walls of the shell are turned inward and secure] y crimped down upon the charge. To crimp any considerable number of shells with the implements now known, becomes a work of considerable magnitude, very laborious and tedious. This is avoided by employing my device herein described.

The object of my invention is to provide means for the convenient and forcible rotation of the grooved disk, and to secure convenient means for forcibly inserting the shell in the groove and pressing it against the end there of until it is properly crimped or closed, and to also provide means for withdrawing the shell from the crimping-disk and from the clamp after the crimping has been accom-. plished. I attain this by means of the device described herein, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of my invention. Fig. 2 is an elevation of the same, presenting the reverse side. Fig. 3 is a plan view of the shell-clamp. Fig. 4 is a front elevation of the same. Fig. 5 is a cross-section on line or m, Fig. 4..

A is the frame, and clamps upon the table by means of the thumb-screw B. The crimping-disk O is screwed upon aspindle, D, which passes through the journal E at the top of the frame. The disk 0 has a groove, F, upon its periphery, around which a cord, G, is passed,

so as to completely encircle the disk, crossing at the top, and droppingdownward therefrom upon both sides of the disk, and having a loop, I, at each end. A carrier, J, is mounted The arms N of the clamp are 63 and at such a height above the platform 0 65 that the edge of the flange of the shell willv pass under the forward ends of the edges N.

The edges N are inclined from the front downward and backward, so that when the carrier is advanced to force the shell into the groove the edges N will come into contact at or near their mid-length with the flange of the shell, and above the center thereof, and when the shell is stopped by contact with the crimpingdisk the inclined edges N will cause the shell to become firmly wedged between the arms and the platform 0, so that the shell will be securely retained by the clamp while the disk is rotating, and also when the carrier is thrown back again, thus withdrawing the shell from the groove in the crimper-disk. A small projection, X, extends from the frame upwardinto the path of the shell, so as to intercept it after it has been drawn away from contact with the crimping-disk, thus leaving the shell free to be removed from the platform 0. The carrier J is secured to the frame by a screw, Q, which plays within a slot, S, in the frame. A curved lever, T, is attached to the front end of the carrier by a screw, V.

This lever passes between two pintles, W W, which project from the side of the frame and serve as bearings against which the lever acts. The lever is bent forward, so that when it is depressed, as shown in Fig. 2, the upper end 5 is thrown forward, thus forcing the carrier toward the crimping-disk. When the lever is elevated, the upper end recedes and the carrier is thrown back, thus withdrawing the shell from the crimper.

The operation of the crimper is as follows: It is clamped to a table, and the operator IOO places his feet in the loops I at the end of the cord. The lever is then elevated, thus throwing back the carrier to receive the shell, which is then placed upon the curved bed 0 in front of the clamp. the operator then depresses the lever, thus forcing the shell forward into the groove and securely wedging it between the arms Nand the carrier-bed 0. At thesame time the operator moves his feet up and down alternately,keepin g the cord taut. This rotates the disk rapidly and with great force, and as considerable pressure can be exerted by means of the lever the end of the shell is rapidly crimped down firmly upon the charge. The lever is then elevated, which throws the can rier back, the shell being retained between the arms N and the platform 0 until the shell comes into contact with the projection or stop X, which holds it while the clamp recedes from it and leaves it loose upon the platform 0, to be removed therefrom by the act of placing an uncrimped shell thereon, when the operation is repeated, no attention being necessary to the shell on the platform 0, as it will roll off upon placing the uncrimped shell thereon.

I am aware that devices forclamping shells have heretofore been employed in connection with a crimping-disk grooved upon its face,

but not upon its periphery, by means of which devices the shell is clamped securely and advanced to and retracted from such crimping disk in a straight line; and I do not broadly claim such a device as a part of my inven tion.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a cartridge shell crimper, of a reciprocating shell carrier and clamp, a crimping disk, and a cord or band encircling such disk and adapted to cause its rotation, the crin'iping-disk being situated in the line of motion of the shell-carrier, substantially as set forth.

2. In a cartridge-shell crimper, and in combination with a rotary crimping-disk, substantially as shown, ahorizontal]y-reciprocating shell-carrier having a shell clamp and platform mounted'thereon, for the purpose set forth.

3. A cartridgeshell crimper consisting of the following elements, in combination with each other, substantially as shown: a frame with a horizontal runway therein, ahorizontally-reciprocating carrier adapted to move therein, a platform or rest for the shell, and aclamp mounted on such carrier, fulcrum projections mounted upon the frame, as shown, and a lever attached to such carrier and engaging with the fulcrum projections upon the frame.

4. The combination, in a cartridgeshell crimper, of the crimpingdisk, the reciprocating shell-carrier platform,and the shell-clam p, the arms of the clamp having edges N inclined from the front end of the arms backward and downward, as shown, whereby the shell is caused to become wedged between the clamp and the platform when the shell is forced against the crimping-disk.

5. In a cartridge-shell crimper substantially such as described, the combination of the horizontally-reciproeating shell clamp and carrier and the stationary lug Z, mounted behind the shell-carrier and in the line of motion of the shell, as set forth, whereby the shell is intercepted and held stationary until the clamp is forced away from the shell and releases it.
