arms cartridges, and has for its object to. provide a devlce of this character whloh embodies novel features of construction whereby the several steps of the stamping are simultaneously performed at each oper..

ation or revolution ofthe main drive shaft,

thereby completing a cartridge at each re' volution and enabling large quantities .of

by unskilled labor.

Further objects 0 which is simple in its construction,which provides for automatically feeding the cartridges through the machine as the stamping of repair or adjustment and which'provides for adjusting the automatic feed of the die blocks so that the movement thereof will be in exactv synchronism with the up and down movements of'the punches.

With these and other objects 1n vlew, the 111V6nt1011 consists 1n certain novel combinations and arrangements of the parts as will-more fully appear as the descrlptlon proceeds, the novel featuresthereof being pointed out in the appended'claims."

For a full understanding of the invention, reference is, to be had to the fo'llows ing description and accompanying draw mgs, in which Figure 1 is a side elevation of a cartridge press constructed in accordance with the invention. 1

I

Referring. to the drawings, which illustrate one embodiment of the invention, the

numeral 1 designates a table which may be drive shaft 9 which isho-rizontally disposed j and is journaled' in suitable bearings 10 provided on the frame 5. Fly wheels 11 are applied to opposite endsfo f the main shaft 9 and power may be applied to this shaft in any suitable manner. It will be obvious that as'the shaft is rotated the cross head 6 will be moved up and down, and one end of the shaft is provided with an eccentric 12 which operates the means for feeding the die blocks. a I I A series of punches '13 project downwardly from the cross head 6, said punches" successively m'creasing in length in the d1-,

rection in which the die blocks travel, and

being properly shaped to, perform the successive stamping operationswhich are re-- quired "to complete the cartridge. Ordrnarily iseve'n stamping operations are re quired for this purpose, and in th'e'present instance the crOsshead-G is provided with.

seven of the punches 13 which project downwardl'yi therefrom and gradually increase 1n length from one end. of the cross head to the opposite end thereof. Each of the die blocks 4: is also provided with seven the openings 14, said die openings being spaced in a manner corresponding to the spacing of the punches 13, and the feeding mechanism being arranged to impart a step by step movement to the die blocks so that in the operation of the machine each of the die openings 1% is brought successively under the several punches 13. Since all seven of the stamping operations are accomplished at each revolution of the main shaft, it will be understood that one complete cartridge will be turned out at each operation of the machine, thereby enabling large quantities of the cartridges to be manufactured and turned out complete in a short period of time. The die blocks 4: travel in the grooved guideway 3, being provided with side flanges 15 of which one is toothed to form a rack, and which travel under flanged guide strips 16 secured to the top of the table. The guide blocks are thus free to travel longitudinally across the table,

although they are held securely against lateral displacement, and the flanged guide strips 16 prevent them from being lifted up with the punches.

The toothed side flanges or racks 15 of the die blocks are engaged by a pinion 17 at the upper end of a vertical shaft 18, the lower end of the vertical shaft being connected by bevel gearing 19 to a horizontal shaft 20 which has a ratchet gear 21 fitted thereon. This ratchet gear is of the conventional construction, being locked with the shaft to rotate the same when turned in one direction, and turning independently of the shaft in the other direction. An oscillating gear wheel 22 meshes with the ratchet gear 21, and is connected by a pitman-23 to a crank disk 24:. A slide 25 extends diametrically across the face of the crank disk 24 and carries a wrist pin 26 which is engaged by the lower end of a cam rod 27, the upper end of the cam rod being provided with a strap 28 which extends around the before mentioned eccentric 12 of the main drive shaft 9. The ends of the slide 25 terminate in threaded stems upon which nuts 29 are threaded, thereby providing for looking the slide and wrist pin 26 in an adjusted position. As the main shaft 9 revolves the eccentric 12 reciprocates the cam rod 27 and this oscillates the crank disk 24, the amplitude of the oscillation depending upon the adjustment of the wrist pin 26, becoming greater as the wrist pin is moved away from the center of the disk. This movement of the crank disk 2% is transmitted to the oscil-.

lating gear 22 through. the pitman 23, with the result that the ratchet gear 21 is rotatedback and forth to produce an intermittent or step by step movement of the die blocks across the top of the table 1.. By adjusting the position of the wrist pin 26 the movement of the die blocks can be brought into exact synchronisni with the movements of the punches, and the adjustment is such that the die blocks remain stationary while the punches are lowered into the die openings 14, although they are advanced a distance equivalent to the spacing between the punches each time the punches are raised. The several die openings are thus brought successively under the different punches 13, with the result that the metal therein is properly stamped and shaped, the last punch being constructed to project the completed cartridge shell from the machine, and one complete cartridge shell being produced at each reciprocation of the cross head.

The die blocks 4 are arranged end to end and have a detachable pivotal connection so that they are fed through the machine in the form of a continuous chain, thereby avoiding all unnecessary handling of the material. One end of each of the die blocks is formed with a tongue 30, while the opposite end thereof is correspondingly recessed at 31, the tongue of each block being received within the recess of the adjacent die block and connected thereto by a pivot pin 32 which passes loosely through corresponding openings therein. The connection between the die blocks is such that a proper spacing of the die openings 14 in the chain of die blocks is maintained throughout the length thereof, and the die blocks can be readily detached from each other at one end of the chain and connected at the opposite end of the chain. The operation of stamp ing the cartridge blanks is thus enabled to be performed rapidly, since the seven necessary stamping operations are performed at one time instead of successively, and the output of an operator is thus greatly multiplied.

A slight modification is shown by Fig. 9, in which an idler 37 is interposed between the pinion 17 and the rack 15 of the die block. This extra pinion provides for'increasing or decreasing the speed with which the die blocks move, as may be necessary when the cartridge press is operating under different conditions.

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