MACHINE FOR CRIMPING CARTRIDGES.

SPECIFICATION forming part of Letters Patent No. 310,306, dated January 6, 1885.

Application filcalNovimher17,1884. (No mode To wZZ whom it HMLZ/ concern.-

Be it known that I, EDWARD PARKER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Crimping Cartridges; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawi ngs constitute part of this specification, and represent, in

Figure 1, a vertical central sectional side view of the machine complete; Fig. 2, a top or I 5 plan view of the machine complete; Fig. 3, a vertical section through the disk and segment enlarged, and showing a cartridge between them as in the process of crimping; Fig. 4, a detached view of the series of teeth.

This invention relates to an improvement in machines for securing the bullet into the shell of a cartridge. This is usually accomplished by spinning or turning the edge of the shell at the mouth inward into the metal of the bullet, and commonly called crimping.

In the machine for which Letters Patent of the United States were granted to the Winchester Repeating Arms Company, assignee of Henry S. Burns, No. 237,480, this crimp- 0 ing operation was performed by means of a disk or table revolving in a horizontal plane, combined with a stationary segment adjacent to said disk, and formed so as to leave a space between the stationary segment and the re- 5 volving disk corresponding to the vertical central section of a completed cartridge, and so that cartridges delivered between said disk and stationary segment would be rolled through between them. The face of either 0 the disk or segment was fitted with an inwardly-projecting sharp-edged rib in a plane corresponding substantially to the plane of the mouth of the shell, and so that as the shell passed this rib the edge of the mouth would 5 be turned inward into or so as to engage the bullet. In practice it has been found that this rolling of the edge of the shell over this inwardly-projecting rib, while it turns the met al inward to prevent the accidental escape of the bullet, at the same time such rolling stretches the metal to such an extent that the bullet will be frequently loose in the not firmly held, as it should be.

To obviate this difficulty is the object of my invention; and it consists in constructing the 5 inwardly-projecting portion of the segment which crimps the shell in the form of a series of points or teeth, which willindent the shell at numerous points inits circumference at the mouth, such indentations being turned inward into the bullet to firmly hold the shell, as more fully hereinafter described.

The machine which 1 illustrate is the same as that in Patent No. 237,480, hereinbefore re ferred to. A general description only will be necessary.

A represents an upright, which forms the support for the operating mechanism. Bis the table, which is supported in a vertical bearing, C, so as to be rotated in a horizontal 7o plane.

Centrally through the table B is a vertical shaft, D, free for rotation independent of the table. This shaft preferably extends d0wnward through bearings E E, and rests on a 7 5 step, F, at the botton.

Above the table B, and made fast to the shaft D, is a disk, G, and so as to revolve in a plane parallel with the plane of the table 13. Revolution is imparted to the shaft D by means of power applied through abevel-pinion, a, on the driving-shaft, working into a corresponding gear, I), on the shaft D, and from the shaft D revolution is communicated to the table B by means of a pinion, d, on theshaft D, working into a gear, a, on a vertical counter-shaft supported in a bearing, H, and carrying a pinion, f, which works into a corresponding gear, 9, on the hub of the table, as seen in Fig.

1. The proportion of the several gears is such 0 that the table is caused to revolve at a less velocity than the disk G. The edge of the disk G in transverse section corresponds in shape substantially to one-half longitudinal section of the cartridge, as seen in Fig. 3 5 that is to say, so as to leave a groove, Ii, be tween the disk and table corresponding to the flange of the head of the cartridge. Thence upward the edge of the disk follows the line of the body of the shell of the cartridge and IOO of the bullet to the center.

At one side, and in the same plane with the shell, or

disk G, is a fixed segment, I, the edge ofwhich facing the edge of the disk G corresponds to the opposite side of the cartridge, (see Fig. 3,) the upper edge. of the segment substantially meeting the upper edge of the disk, the face of the segment corresponding to the shape of the complete cartridge.

On the face of the segment I, and in a plane corresponding to the upper or month end of the shell, is a series of points or teeth, a, (see Fig. 4,) more or less in number, the series being of a length substantially. equal to the circumference of the shell to be crimped.

In operation the cartridges are set head down on the table B, and by its revolution in the direction indicated by the arrow, Fig. 2, the cartridges are delivered between the segment I and the disk G, conducted thereto by a guide, L. The first cartridge is engaged by the revolving disk on one side, the fixed segment I engaging the opposite surface, and so that as the disk G continues its revolution the cartridge will be rolled between its surface and that of the fixed segment, and being so' rolled between the two,the teeth a willindent the cartridge at its mouth, as indicated at m, Fig. 3, and turn the mouth of the shell into the metal of the bullet, so as to secure the bullet to the shell. This operation of indenting the shell avoids the stretching of the metal at the mouth,which unavoidably follows the rolling of the shell against a continuous edge or rib, as in the usual method of crimping, and consequently the bullet is more firmly held and supported in the shell than by such crimping; but yet the resistance to throwing the bullet from the shell by explosion is less than a continuous rib to the extent that the series of indentations are less than the full circumference of the shell. The table B is made to revolve at a less velocity than the. disk E, in order that as each cartridge is taken between the disk and segment an accelerated forward movement is given to each successive cartridge, taking it away from the next, which prevents the possibility of the cartridge coming in contact with each other while passing through the crimping operation.

While I prefer to make the adjacent faces of the revolving disk and segment correspond to the shape of the entire cartridge, such corresponding shape may extend only to the shell itself, as indicated in broken lines, Fig. 3, and while I prefer to arrange the teeth on the stationary segment they may be made on the revolving disk, as indicated in broken lines, Fig. 3.

As before stated, the construction of the machine is the same as that in the patent hereinbefore referred to, and I herein make no claim to the construction shown and described in said patent; but

\Vhat I do claim as my invention isy In a machine for crimping cartridges, the combination ofa revolving disk and a fixed segment in the same plane with the disk, the space between the disk and segment correspondin g substantially to the shape of the cartridge, with a series of teeth projecting into the space between the segment and disk, and

substantially in the plane of the mouth of the shell, substantially as described, and whereby as the cartridge is rotated between said disk and segment a series of indentations will be made around the mouth of the shell into the bullet, substantially as specified.

EDXVARD PARKER.
