CARTRlDGE-LOAlJING MACHINE.-

SPECIPICATION forming part of Letters Patent No. 384,089, dated June 5, 1888. Application filed August 2, 1887. Serial No. 245,979. (No model.)

To aZZ whom it may concern.-

Be it known that I, PRENTISS SELBY, of Oakland, Alameda county, State of California, have invented an Improvement in Cartridge- Loading Machines; and I hereby declare the following to be a full, clear, and exact description of the same. I My invention relates to improvements in cartridge-loading machines.

The feature ofmy present invention is an improved device for crimping the shells after the powder, shot, and wads are in place.

It consists of a vertically-moving stem or spindle, with means for rotating the same, and an arrangement of springs and weighted arms whereby the operation is more perfectly per- -formed.

Referring to the accompanying drawing for a more complete explanation of my invention, the figure is a view showing a section of the rotary table with one of the cylindrical chamhers for holding the shell and the mechanism for crimping the shell when it is brought to the proper point.

A is the table, having the chambers B, into which the shells are deposited by mechanism which I have not here shown, as it forms no part of my invention.

0 is the vertical stem or spindle passing through the lower guide, D, and having the crimping-flangeE fixed to its lower end, so as to 'be in position to be pressed upon the cartridge contained in the chamber or hole 13 to crimp its upper open end when properly presented.

5 The upper end of the spindle C is made c0ni cal in shape, and the long heavy rod F, which extends up through the door or guide G, has

a corresponding socket in its lower end, which fits over the spindleC tightly enough, so that 40 the two will be rotated together.

H is a pulley around which the drivingbelt passes from the source of power, and this pulley rotates the shaft. F and the spindle G, turuing in the guides, so as tooanse the crimping- '2; 5 flange E to be rotated for the purpose of crimping the shell.

The spindle 0 passes through an arm or guide, I, which is caused to rise and fall by means of a crank-wheel, J, and a connecting- 501 pitman, K. This crimping movement has heretofore been performed by means of a sharp spiral thread or screw formed upon the spindle'of the crimper and aunt which fits said thread and moves upward and downward, so as to rotate the spindle when the crimper is fitted over the shell; but this is objectionable in some particulars, and' especially because it is difficult to bring the exact pressure desired upon a crimper, and because it is impossible to bring this pressure upon the shell 'gradu- 6o ally. In the present case 1 effect this by means of springs L, which surround thevspindle O and rest upon an adjustable collar, M. "Ihis collar may be raised or lowered upon the spin-. dle, according to the amount of pressure de sired, and when the bar I is loweredby the movement of the crank-wheel J the crimper first rests upon the edge of the cartridge-shell, anda further downward movement of the bar, which is produced'by the rotation of the crank, 7: brings the pressure of the bar upon the top of the spring L, thus pressing the crimper grad ually downward with whatever force may be desired. As the weight of the rod F and the spindle C is considerable, I employ the springs N and O to relieve this weight and to allow the crimper to come down gradually upon the shell. The rod F, which extends upward a, considerable distance through the guide or door G, has the spring 0, surrounding its upper end and resting upon the top of the upper guide, while the upper end of the rod has a head or collar, P, which rests upon the top of the spring, thus relieving the rod 0 and crimper of too great a weight. The spring N rests upon the top of the bar I or an adjustable sleeve through which the spindle 0 passes, and the collar Q, which is fixed to the rod 0, rests upon this spring. It will be manifest from this construction that when the crank of the wheel J is at its highest point the crimper will be raised above the cartridge, and the weight of the spindle C and rod F 'will be supported upon the springs N and 0. 'As the crankwheel performs its revolution, allowing the bar I to move downward, the edge of the crimper E will first press lightly upon the top of the shell, the whole being kept in rapid rotation by means of the belt and belt-pulley H, and as the supporting-bar I continues its descent the weight of the spindle G-and rod F IOC will gradually be brought altogether upon the I the crimper down upon the edge of the sheil nation with the supporti ngnrni through which erin'ipeh- A further descent of the her I causes itto commence pressingupon the top of the spring L, and the force brought upon this spring is increased to any desired point, .depending upon the position of the collar M and the consequent tension of the spring L. 1

By this construction I am enabled to bring with a gentle and graduaily-incrensing press ure instead of with r i abrupt blow, in the former construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patient, is I p 1. In a. certridge'doziding machine, the vertically-moving criinpersteni and the rotating spindle seated upon its upper end, in coinhi= the stem passes,-

pitmnn connected with one end of said arm, a, ernnk wheel to which the opposite end of the pitmun' is attached, the collars M and Q on the verticalsteni, and the springs bearing against the collars, substantially as described.

2. In a cartridge loading machine, the vertical spindle having the c'riniper attached to the lower end, the rising and falling supportingerm, in combination with the spring N and collar Q, by which the weight of the spindle is supported upon the arm from above, and the spring L and collar M upon the spindle beneath the arm. whereby the pressure of the arm is gradually increased by its descent, substentinlly as herein described.

3. The vertical spindle carrying the cartridge-crimper at its lower end, the rising and falling arm through which the spindle passes, the collars, and springs, as shown, in combination with the vertical rod extending through guides in a line above the spindle, having a tapering socket in the lower end to fit the head of the spindle, and a pulley by which the rod and spindle are caused to rotate, substantially as herein described.

4. The vertical rising and falling spindle 5 carrying a crimping-head at its lower end and having supporting and operating springs and collars, as shown, the vertical rod standing in line above the spindle, having a tapering socket in its lower end fitting 2. correspondingly-shaped head of the spindle, and a pulley on said red through which n rotary motion is imparted, in combination with the spring 0, surrounding the rod, and the collar or head P, whereby the weight of the rod and spindleis automatically reduced as they move downward, substantially as herein described.

In witness whereof I have hereunto set my hand.

PRENTISS SELBY.
