MUSHROOM-BULLET.

vented a new and useful Improvement in Mushroom-Bullets, and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to

be a full, clear, and exact description of the same, and which said drawings constitute "part of this application, and represent, in

Figure 1, a view in side elevation of a bullet constructed in accordance with my invention. Fig. 2, a viewthereof in central longitudinal section on the line A B of Fig. 1, showing the tip in full and illustrating one of the forms which the anchorage of the solid point of the bullet in the soft metal of the core may assume.

My invention relates to an improvement in that class of sharp-nosed jacketed mushroom bullets provided with a sharp solid point, the object being to produce at a low cost a superior bullet of the character described.

With these ends in view, my invention consists in a mushroom bullet having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein,

shown, I employ solid, conical tip, 2, preferably made of aluminum, or some other suitable metal, and formed with a heavy shank, 3, furnished with circumferential ribs, 4, the said shank and ribs being embedded in the soft core, 5, of the bullet ruereby the'tip is firmly held against lonudinal displacement. The core, 5, is int-lo :l in jacket, 6, the open edge of which i, separated from the tip, 2, by a circumferential accommodation space, 7, into which a portion of the metal of the soft metal core exudes to form an exposed band, 8, bridging the space between the point and the edge of the jacket and completing the contour of the bullet the rear end of which 'is cylindrical, and the forward end of which tapers to Specification of Letters Patent.

a point. The accommodation space, 7, is an important feature of my improved bullet from a manufacturing standpoint as it pro vides for taking up or accommodating for all of those minute variations occurring almost beyond prevention in the length of the tip, 2, and jacket, 6. The dies in which the parts of the bullet are swaged together are uniform, of course, in their dimensions and the completed bullet over all corresponds to the internal length of the die. Now, as the width of the accommodation space, 7, may vary without harm, it is ap parentthat it provides for taking up any minute variations in the initial length of the parts of the bullet.

Of course, the point, 2, may be anchored in the soft metal core, 5, in a great variety of ways without departing from my invention.

At the time of impact the overhanging inner edge or annular shoulder, 9, of the solid tip, 2,.jamsits way inside of the beveled edge, 10, of the jacket and tears and spreads the same open so as to effect the mushrooming of the bullet. By preference, the edge of the jacket is beveled as at 10, though this is not essential.

I claim:

1. As a new article of manufacture, a sharp-nosed, solid point mushroom bullet the rear end of which is cylindrical and the forward end of which tapers to a point, the said bullet having a soft metal core, a jacket therefor, and a solid conical point projecting beyond the forward end of the said jacket and continuing the taper of the forward end thereof to a sharp point, adapted at its inner end to be anchored in the metal of the core, and formed at the inner end of its portion of the soft metal core is exuded.

2. A mushroom bullet having a soft metal core, a jacket therefor, and a solid point formed with a shank by which the point is anchored in the soft metal core, the over-i hanging inner end of the point being separated from the edge of the jacket by a circumferential accommodation space into which a, portion of the soft metal of the core is exuded, and the edge of the jacket being beveled to coact at the time of mushrooming With the overhanging inner end of the point in spreading the jacket open.

In testimony whereof, I have signed this specification-in the presence of tWo subscribing Witnesses.
