To all whom it ntay concern:

Be it known that I, HENRY W; STARK- wnA'r-msn, J citizenof' the United States, residing at New Hnven inthe county of New Haven and State of Connecticut, have invented a new and useful Improvement in Mushrooming Bullets; and I do hereby de- Clare the "following, when taken in comics-- tion' with the accompanying drnwings'and.

into port of this application, and represent, in

' drawn sheet-metal jacket of the bullet shall consists in a mushrooming inclose the soft-metal slug so that bullets will not be deformed in handling, nor when functioning in the magazine of the gun.

The object of my present iuvention'is to combine the advantages of full-jncketeii and semi-jacketed bullets and to produce a hullei which will readily mushroom, and yet which will not he deforms in handling.

Viith these ends in View, mi? invention bull ht having a soft-metal slug formed in its hose with a concentric cavity, a sheet-metal jacket inclosiug the sin exo "it for an annular spacesurrounding t o sairi. cavity therein, and a hollow sheet metal cop inserted into the seid cavity so as to close the outer end thereof.

In carrying out my invention as herein shown, I employ it short cylindrical slug 2 of lead or equivalent soft-metal having a relstively deep, concentric cyiindrlcnl cavity 3 in its forwuri'l end. This slug is inserted into n. drnwnshset metal jacket at of relatively hard metal, the side walls of which are slightly tapered as shown, thoughthis .or point of the bullet.

is not necessary. The said slugfl I 4 when combinod'as shown in Fig. .2,--are subjected to an assembling operation in" Patented Junea, 191s,

which the open end of the jacket is' closed down upon the rounded forward end of the slug, the jacket and slug being proportioned in length so that the edge of-the jacket will leave that portion of the sill ately surrounding the cavity 3 tereof' ex? posed in the form of a ring or annulus .5.

The cavity 3 in the slug 2 isprov'ideil for I facilitating the mushrooming thebul-lo't. To prevent this cavity from accumulating dirt and also from filling with air and impeding the progress of the bullet in its" fiight, and also to prevent the exp0se(l portion of the slug from being mutilated or deformed, I "insert a relatively sofbmetelcylindrical cap 5 into thecavityB, the outer end of the cap beingmacie sufficiently crownmg to conform to the general curvature of the outer end of the slug and jacket so as" to result in a symmet ical curve for the nOSe sembliug operation, it will flow "outward to the end of the cap as shown in Fig. '2.
