STEEL PROJECTILE.
Specification of Letters Patent.
Patented Dec. 12, 1905.
Application filed March 31, 1905. Serial No. 253,087.
T0 00% whom it may concern.-
Beit known that I, ALBERT HAASE, asubject of the German Emperor, and a resident of Essen-on-the Ruhr, (Riittenscheid,) Germany, have invented certain new and useful Improvements in Steel Projectiles, of which the following is a specification.
The present invention relates to steel projectiles provided with a cavity filled with heavy metal.
The object of the invention is to provide a projectile having great penetrating force and of simple and economical construction.
The invention is best adapted for embodiment in projectiles for use in small-calibered firearms.
In the accompanying drawings, in which one mode of construction of the improved projectile is illustrated by way of example, Figure l is a longitudinal section of the projectile, and Fig. 2 is a side view of the front part of the projectile.
The projectile A is preferably made from steel and is at its rear end provided with a cavity having very thin steel walls a. If, for instance, the projectile is to be used in 7 7 millimeter-calibered firearms, the thickness of the walls a is about 0.5 to 0.6 millimeters. The cavity is provided with a filling B, consisting of lead or other metal of high specific gravity. The cavity is located in the rear portion of the projectile only, and in front of the cavity there is still left an essentially cylindrical steel projectile-body with the projectile-point. The hollow cylindrical portion of the projectile is entirely or partly covered by a jacket C of soft material, such as copper or nickel, which takes into the rifling of the barrel to rotate the projectile in firing.
When the improved projectile hits, for instance the ordinary protecting shield of a field-gun and is partially checked in its flight, the mass of the filling B moves forward relatively to the projectile under its own inertia, with the result that said filling flows or expands outwardly and causes the weak cylindrical wall a to burst from the main body of the projectile and carry with it the ring C. The separation occurs at the place where the pressure is highestthat is to say, at the division-line X between the hollow portion and the solid front portion. The separation takes place almost simultaneously with the projectile hitting the shield, and the front part of the projectile alone, which now has the appearance shownfin Fig. 2, continues the flight. The separated part a, with the filling B and the ring 0, either remains embedded in the protecting-shield or falls in front of the shield.
It will readily be understood when considering the manner of operation above described that the penetrating force of the projectile corresponds almost during the entire penetrating movement to the kinetic energy of the complete projectile. As. furthermore, the ring is located on the cavity portion only and the said portion is broken away, when the projectile hits the shield the ring does not impede the penetrating movement of the projectile, and the penetrating-projectile portion consequently acts like a smooth projectile and continues its flight behind the shield with very slightly-diminished speed. When the whole projectile hits the bodies of human beings or of animals, it retains its original shape.
Having thus described the invention, what is claimed is 1. A projectile comprising a body portion and a rear hollow portion; said rear hollow portion containing a part which, on impact of the projectile, moves forward therein and expands radially to burst the hollow portion from the body of the projectile.
2. A projectile comprising a body portion and a rear hollow portion with a thin cylindrical wall; said rear hollow portion contain-,
ing a metallic body movable relatively thereto under impact of the projectile and expanding radially under such movement to burst the hollow portion from the 'body of the projectile.
3. A projectile comprising a solid main body portion and a hollow rear portion having a thin cylindrical wall; said rear hollow portion containing a metal filling which, under impact of the projectile, flows in the direction of its flight and by such flowing, expands outwardly and separates the hollow cylindricalportion from the main body of the projectile.
A. A steel projectile comprising a solid front body portion and a hollow rear portion provided with a filling of metal of higher specific gravity than steel the filling being constructed to move forward within the hollow portion and separate the hollow portion from the front portion.
5. Asteel projectile comprising asolil front The foregoing specification Signed at Esse'rF body portion, a hollow rear portion with a onV-the-Ruhr, (Diisseldorfl) this 20th day of thin cylindrical Wall, a filling in said hollow March, 1905.
