T. R. BARNEY. CARTRIDGE GRIMPING MACHINE.

No. 531,495. Patented Dec. 25 1894.

iillllllll-llllll G'EidThe pins or studs H H. The piece G i smooth.

is closed at the back end, in which is a screw- 'threaded socket g for the end of the spindle.

The rim at the opposite,open end is chamfered and the cylindrical space within is bpr'ed out The core G at the front end is of suitabl smaller diameter than the surrounding cy inder to admit the rim-portion of the shell between the two parts, and'behi'nd this reduced portion the body of the core has the same diameter as the chamber of the piece G,

and is fitted in that piece to work smoothly,

' The outer end of the core is closed bya head g, which is usually countersunk in the center, as shown in Fig. 5, and the core is hollowed out to receive a stid spiral-spring K that sets against the closed back of the piece G and against the back of the solid head of;

dial lines across the annular recess-between the core and the surrounding body G, and that portion of the pin which sets across the crimping-recess is usually grooved as shown in Figs. 2 and 6 for the purpose of producing a rounded-edge on the rim of the cartridge.

The cri roping-head thus constructed iscomplete in itself and entirely independent of the spindle, so that heads of different sizes, that is to say with crimping-recesses and cores suitable for crimping-cartridges of the differcut sizes, can be furnished with one machine, and one head can readily and quickly be substituted for another according to the size of cartridge [0 be operated on. This enables much better work to be turned out than by operating on cartridges of different sizes with the same core as is the practice in other construction of machines where that piece is a part of the spindle.

The end of the driving-spindle Bis cut with a screw 12 that fits the socket in the back end of the crimpingreadily detached by revolving it backward on the spindle.

L is the part site spindle to take the backend of the car tridge, Thispart which I have termed the revolving-head is countersunk and the inner face all around the recess or depression is finished on a taper increasing in diameter from the bottom face of the recess outward to the edge of the standing rim, and this ta, ering face L is milled or rough-cut like i: 0 surface of a tile to insure a firm hold and grip head, so that the latter is fixed on the end of the oppoof cartridge into the'recess; so that while the be changed from time to time the same revolving-head will answer for several sizes of cartridges.

Having thus fully described myinvention, what I claim as new therein, and desire to secure by Letters Patent, is

l 1. In a cartridge-crimping tool, or machine, the combination of two revolving spindles, geared into a bevel driving-wheel on. opposite sides of the center and receiving simultaneous rotation in opposite directions from the motion of said driver, a crimping-head on the of the cartridge-shell a head on the end of the opposite spindle adapted to grip the head of the cartridge and means for moving said head longitudinally toward the opposite head to feed the edge of the cartridge shell forward as hereinbefore described. I I

2.- In a cartridge crim ping tool, or machine, the combination of a suitable frame, a bevel driving-gear mounted therein, two separate revolving spindles B B geared into said driver on opposite sides of its center to receive motion therefrom simultaneously in contrary crimping-head fixed on the end of one spindle composed of a cylindrical-body G and,a yielding cylindrical core G movable therein, the revolving-head Lfixed on the end of the opposite spindle having a daring recess L with roughened face to grip the head of the cartridge, the spindle of the said revolving head being movable longitudinally, and the handlever E connected tosaid spindle as a means for moving the same forward to advance the cartridge shell into the crimplnghead, substantially as hcreinbefore described;

3. In a cartridge crimping-molds. crimping head consisting of the hollow cylindrical body G, the cylindrical-cordial" movable longitudinally in the body but rotatid iwith it, and of 'rnos. n. BARNEY. [L.s.]

fi tr-uction also admits several different sizes crimping-head on the opposite spindle may end of one spindle adapted to turn the end during the crimping operation,substantially directions by the rotation of said driver, the

smaller diameter at the front end than the surrounding body,the spiral springK and the
