Specification of Letters Patent. Patented Sept. 29, 1914:.

SeriaI No. 808,538.

Application filed December 24, 1913.

To all whom it may concern Be it known that I, FRANK O. HOAGLAND, a citizen of the United States, residing in Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Projectiles, of which the following is a specification.

This invention relates to that class of elongated projectiles in which a soft-metal core is protected by a point-cap or jackettip applied thereon, either with or without being accompanied by a body casing or jacket for the rearward part of the core; and the present improvements have for their object to furnish a simple and efiective means whereby the point-cap or covering member may be held in position on the core without requiring any portion of such cap or member to be turned or indented inwardly so as to take into the core, as when using an inwardly turned flange or inwardly-extending rojections formed by exterior-1y indenting the wall of the point-cap or analogous corecovering member.

In the accompanying drawing, forming a part of this specification, Figure 1 is a side elevation of a projectile made in accordance with my present improvements, and showing the projectile provided with a main: core case H extending forwardly (toward the right hand) to about midway of the point-portion of the core, and with a pointcap or jacket-tip, P, secured on the point of the core. Fig. 1* is a view of the point-cap, P, in the same position as illustrated in Fig. 1 but shown in section. Fig. 2 is a longitudinal sectional view of the projectile as seen from below in Fig. 1. Fig. 2 is a transverse section through the projectile in the line ZZ, Fig. 2, showing the parts on the left-hand of said line as seen from a position at the right-hand thereof. Fig. 3 illustrates a slightly modified arrangement of the body casing or jacket relatively to the point-cap and core of the projectile, some portions of this view being broken away for more clearly showing the details of the construction. Fig. 3 is an end view of the form of projectile shown in Fig. 3, as seen from the right hand in said figure. Figs. 4:, 5 and 6 illustrate further variations in the arrangement of the point-cap relatively to other parts of the projectile.

Similar characters represent like parts in all of the views.

The point-cap, which is designated in a general way byP, is adapted for use on expandible projectiles of the so called mushroom class, and for use in connection with a main core-casing or body-jacket, as H, arranged to cover the body as well as a part of the point portion of the core, and arranged with its forward edge 2 close to the rearwardedge 3 of the point-cap, as in Figs. 1 and 2; or with an intervening space, 9, between said forward edge el and said rearward edge 3 of the point cap, P, as in Fig. 3 or, with the forward edgeQ of the jacket underlying the rearward edge 3 of the point cap, as in Fig. 4:.

In practice, the core may be made and finished in various ways, among which are casting and swaging. Then the point-cap is provided with the openings, 5, whether these be circular (as heretofore shown), elliptical or'polygonal in outline,or of other suitable shape, not shown,-the core metal may have extending therefrom one or more projections, as 7, for filling said openings and thereby locking the point-cap in place upon the point portion 0 of the core C. When the core is formed by casting the metalinto the pointcap,-this being done by means of a suitable mold,the molten metal may thus be run out into said openings 5, and thereby fill the same and make the outside of the finished projectile of a smooth and regular form. In those cases in which the core is I formed in a well-known manner by a swaging operation, similar outwardly extending parts of the core may be formed within said openings 5 by the method-of extrusion, or flowage. It will, of course, be understood that in any given instance such operations as here referred to may be varied in different ways according to the custom of such metalworking arts and within the scope and limits of the improvement herein illustrated and described.

From a comparison of the several Views as herein describcd,-especially the sectional portions of Figs. 2, 3, 4: and 5,it will now be evident that the functions and mode of action, and also the advantages, of the described cap-retaining core-projections are substantially the same in each of the arrangements illustrated, and whether those projections are one, two or three in number. When it is desired for any reason to restrict the area of the exposed core-metal surface, it is, of course, only necessary to Having thus described myimproved proreduce accordingly the diameter of the openjectile, I claim t u g I ings5 in the cap Pyand' then to make such 1.
