JOHN B. DUNCAN, OF WOLF, WYOMING.
MUSHROOM-BULLET.
Specification of Letters Patent.
Patented oea's, 1915.
Application filed September 29,1914. Serial No. 864,138.
To aZZ whom may concern:
Be it known that 1, JOHN B. lJLSCAN, a citizen of the United States, residing at Wolf, in the county of Sheridan and State of \Vyoming, have invented new and useful Improven'lents in Mushroom Bullets, of
y This invention relates to projectiles and in particular to those bullets used in small arms which are generally known as mushroom bullets.
The primary object of the invention is to provide a bullet of this type whose body is constructed of lead or other soft metal and is incased within a thin, yet tough jacket of suitable metal, such as an alloy of copper and nickel, or the like. The sharp point of the bullet is constituted by a distinct member of hard metal, such as steel, and this member is formed'and arranged within the forward end of the body in such a manner that it will recede when the bullet strikes an object, to free the front edge of the jacket,
point which latter will catch in the object fired upon and will be forced rearwardly into the opening formed by the rearwardly driven member, so as to expand the bullet and produce the desired mushroom effect.
The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which:
Figure 1 is a side elevation of the pre ferred embodiment of the invention; Fig. 2 is a longitudinal sectional view taken through the same; Fig. 3 is a similar view showing one form which the bullet may take as it begins to mushroom, the point member having been driven back initially to a depth equal to the length of its active point; Fig. 4 is a similar view at a later stage in the mushrooming; Fig. 5 is a longitudinal sectional View taken through a modified form of bullet; and, Fig. 6 is a similar view of a further modification.
In the drawing, the numeral 1 designates the elongated body of the bullet which is constructed preferably of lead or other soft metal, and which is inclosed within a cupronickel jacket 2, it being understood that the jacket may be constructed of some other tough and malleable metal that proves more desirable. The jacket 2 and the body are tapered at their free end but are cut away w edging to provide an opening Sin the former and a recess 4 1n the latter communicating therewith. l V
"T he point member 5 of the bullet is ada-pti ed to be mounted within the body recess 4: with its active, pointed end 6 projecting outwardly through the opening in the jacket to complete the point of the bullet. In Figs. 1
to 4: inclusive, the point member is shown as being cylindrical in shape throughout a ma or portion of its length, its rear end being constructed conical in shape as at 7. 1n Fig. 5.,however, the point member is provided with a conical rear end 8 which merges directly with the active point, there being no cylindrical portion. In Fig. 6, the rear, wedging end 9 of the point member is constructed similar to the wedging end-8 of the point member in Fig. 5, but differs therefrom in that its outer periphery is axially concave. k V
When a bullet constructed in the manner shown in Figs. 1 to 4 inclusive, strikes the ob.- ject fired upon, be driven back into the soft body with the result that the metal of the body and the jacket will be expanded by the action of the wedging point 7. Owing to the fact that the wedging point is'spaced from the active, penetrating point 6 by the cylindrical portion 5, the body of the bullet will be expanded at a point spaced from the forward edge of the jacket, during the movement of the point member as its point 6 recedes into the body as shown particularly in Fig. 3 of the drawing. As soon as the edge of the-jacket has been freed in this manner, it will catch in the substance being penetrated by the bullet and will be forced inwardly into the recess 4 and the extension of the same produced by the rearwardly driven point member so that the bullet will expand to a great degree and will assume a form similar to that shown in Fig. l of the drawing. The mushrooming is started by the expansion of the medial portion of the body and jacket and is completed by the crushing in of the forward edge of the jacket and the adjacent metal of the body which formsthe wall of the .recess 4.
In the remaining forms of the device, the point is constructed and arranged with relation to the penetrating point so that the expansion of the body will commence at theforwarc end of the same and so the hard point member will that the vvall of the opening created in the body willbe very thin, therebyrendering the'same' more readily expansible.
From" the foregoing description, taken in connection With'the accompanying drawing, it should be apparent that I have provided a bullet whose active point is constructed of hard metal and thus will not batter or Wear off so as to become blunt or illshaped While having its forward end cut away, and a point member mounted Within the forward end of the body and having a penetrating point Whose lines merge with those of the jacket, the rear end of the point member being tapered to form a Wedging portion, the
' wedgin'g portion of the point member being separated from the penetrating point by an elongated portion of uniform thickness, the juncture of the rear Wedge portion With the body of the pointed member being spaced from the" cut away forward end of said jacket.
In testimony whereof I affix my signature in presence of tvvo Witnesses.
