To all whom it may concern: I

Be it known thatl, FRANK O. HOAGLAND, a citizen of the United States, residing at Bridgeport, county of F airfield, State of Connecticut, have invented an Improvement in Hollow-Point Bullets, (Case A,) of which the following is a specification. V

This invention relates to the class of bullets broadly designated as hollow point bullets,"the forward end of which willmush room, 71. e. flatten or spread out, upon impact with an objective, and the invention has for its object to provide a bullet of this type which shall be relativel inexpensive to p roduce and exceedingly e ective 1n use, owin to its superior mushrooming quality, an shall moreover he admirably adapted for use as an illuminating bullet,

With these and other objects in view I have devised the novel bullet which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to 1ndicate the several parts.

Figure 1 is a. sectional view showing the slug from which my novel bulletis' formed,

and also the action of the first die thereon Fig.2 a planview of the slug corre onding with Fig. 1, and showing the die in horizontal section; Fig. 3 a. view partly in elevation and partly in section showing the bullet during the process of formation, after the action of the first and second dies, and before the action of the third die; Fig. 4 an elevation of the partly formed bullet as seen from the left in Fig. 3; Fig. 5 an elevation of the completed bullet; Figafi an elevation of a modified form of slu and Fig. 7 is a plan view corresponding t erewith.

10 denotes one form of slu from which my novel bullet may, he forms the essential features of which are a cup-she ed recess 11 in its forward end surrounded y a wall 12. The exact configuration of the recess or the height of the wall are not essential features of the invention. I preferably however, as shown in the drawing, form the outerside of the wall of the slug parallel with the axis thereof and form the'wall of diminishing thickness from the base of the recess outward- The bullet is completed by swaging tools, indicated'by 13, the action of which is to split the wall into four sections and'to cause said sections to close the tip of the bullet and to overlap, as indicated in Fig. 8.

by 19, the edges of which Itmakes no difierence so far as the principle of the invention concerned just how the swaging tools are arranged to operate. It is thought suflicient for the specification to state-that the action of the first tool, which maybe single or double acting, is toshear out two opposite sections from the wall of the tip, to told one section, as 14, over inward, and to fold the second section, indicated by 15, over inward. upon it, then another tool or a member of a double acting tool folds the third section, indicated y 16, over inward upon section lo, after which another tool or a member of a double acting tool folds the fourth section indicated by 17, inward over upon section. 16. In Fig. 3, the first and second sections, indicated by 14: and 15 respectively, are shown as folded to place, the third section, indicated. by 16, is ready to be folded to place by the next action, after which the fourth section, which faces section 16 but is cut away in the drawing, is folded to place, leaving the sections superposed. It is not considered necessary to illustrate in detail the operation of these swaging tools, as their action will be obvious to anyone skilled in the art. The folding or closing over-of the four sections leaves a closed central recess 18' in the forward end of the bullet, which may be made larger or smaller, asmay be to quired, by lengthening or thickening (either or both) the wall surrounding recess 11 in the slug. The swuging together of the sec? tions makes the closed central recess water and grease proof. The bullet comprising this invention is admirably adapted to use as an illuminating bullet. 0 change of manufacture, but a mass of a "suitable fiashingcompound, ind icuicd by 20, that will produce a flame or a puff of smoke or both purposes of this is required in the process when ignited by impact, is placed in the recess 11 in the slug and the sections the wall closed over it in the manner already described. I h

The form illustrated in Figs. 6 were diflers in that the wall of the slug as formed comprises a plurality of-scctions, indicated are convex curves. These sections may he folded over successively or simultaneously as they do not overlap. The edges are swaged tightly to ether and close the central. recess as ellectualy as in the other form, making it water and ice" grease proof and protecting a compound in bullet and being closed inward in the form the recess, if used. of superposed overlapping sections.
