1 Claim. 1

This invention relates to projectiles, more particularly to projectiles of the armor-piercing type having a relatively long ogive.

'In a copending application Serial No. 455,323, filed August 19, 1942, we have described an ormor-piercing projectile of the rifle grenade type which employs a cone shaped member projecting into the charge, and a relatively long ogive. The present invention is directed to projectiles of large size or diameter such as are discharged from a gun, and which employ a cone and relatively long ogive for the same purpose as described in said copending application.

The present invention is directed, in projectiles of the above character, to an improved means for mounting the cone and ogive which is so constructed as to facilitate the loading of the explosive charge.

Accordingly, one of the objects of the present invention is to provide a new and improved means for connecting the ogive with the body of the projectile.

Another object is to provide an ogive mounting means of such construction that this means, with the ogive removed, may be employed to support the projectile or shell in an upright position to facilitate the loading of the same with the explosive charge, which means also securely holds the cone-shaped member in position within th body of the projectile.

With the above and other objects in view, the present invention consists in certain features of construction and combinations of parts to be hereinafter described with reference to the accompanying drawing, and then claimed.

In the drawing which illustrates a suitable embodiment of the invention,

Figure l is a longitudinal sectional view of the projectile,

Figure 2 is a view similar to Figure l but with the ogive removed, and

Figure 3 is a fragmentary sectional view of a slightly modified mounting means.

In the accompanying drawing in which like numerals refer to like parts throughout the views, the numeral I indicates a projectile or shell body having a receiving chamber II for the explosive charge I2. The trailing end of the chamber II is internally threaded at I3 to threadedly receive the detonator housing I4. 'lhe opposite or leading end of the chamber II is counter-bored to provide a seat I5 and a wall of enlarged diameter which is internally threaded as indicated at I6. The cone member I1 is formed with a circumferential flange I8 which as 2 shown in Figure l is seated against the shoulder or seat I5.

In accordance with the present invention, the cone member I! is very rigidly held in place by an annular ring I9 which is externally threaded as indicated at 20 in Figure 2 and threadedly received by the internal threads IE to abut and securely clamp the flange I8 against the seat I5, A portion of the threaded portion of the ring I9 projects beyond the end of the shell body I0 for threadedly receiving the ogive 2|.

The ogive 2|, as shown in the drawing, is of conical shape and internally threaded so that it can be threaded onto the projecting threaded portion of the ring I9.

In loading the shell, the ogive 2I is removed and the shell body I0 is disposed in an upright position, as shown in Figure 2, the projecting portion of the annular ring 20 serving as a supporting base to maintain the body II! in a relatively stable upright position. The explosive charge I2 may then be poured into the receiving chamber II to the desired level, after which the detonator housing I4 is threaded into position and the seal 22 inserted and flattened as indicated at the right in Figure 1. The seal 22 is shown at the left in Figure 1 in its unflattened condition, The ogive may then be threaded onto the projecting portion of the ring 20.

The mounting means of the present invention thus provides not only an eflicient means for mounting the ogive and clamping the cone in position but also provides a means for supporting the shell during loading with the explosive charge, thus eliminating the necessity of providing special jig fixtures for supporting the shells during the loading operation.

The slightly modified construction of Figure 3 which is particularly adaptable for use when it is desired to employ a standard diameter of cone in shells of difierent internal diameters, that is a cone in which the circumferential flange I8 is not of suflicient diameter to engage the seat I5, embodies an externally threaded spanner nut 23 which is threaded into the counter bore to engage the seat I5. This nut is of such internal diameter as to project radially inwardly beyond the edge of the seat I5 and thus in itself provide the seat for the flange I8 of the cone member II, Apart from this, the construction is the same as shown in Figure 1, the externally threaded ring I9, in addition to providing the mount for the ogive, also clamps the cone flange I8 against the nut 23.

Obviously, various changes may be made in the detailed construction and arrangement of parts without departing from the spirit and substance of the invention defined by the appended claim.

What is claimed is:

In a projectile, a hollow casing having open ends, one of said open ends having a counterbore providing an annular shoulder therein, a conical member extending within said counterbore and having a peripheral flange abutting said shoulder, an externally threaded annular ring threadediy connected with the wall of said counter-bore and clamping said flange against said shoulder, said ring extending axially beyond said one open end, and a shell-like ogive having internal threads at one end, said internal threads having threaded engagement with the threads of said ring, said ring with the ogive removed providing means for supporting the casing in an upright position to permit loading thereof with an explosive charge through the opposite end.
