Patented Aug; 10, 1943 PROJECTILE William J. Landen, Arlington, Va. Application January 16, 1940, Serial No. 314,100
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 3 Claims.
The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royaltythereon.
The subject of this invention is a projectile.
The purpose of the invention is to provide an explosive projectile which may be inexpensively and easily fabricated and which is arranged to receive a simple firing mechanism.
The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in. the accompanying drawing in which: Fig. 1 is a longitudinal sectional View of a pro- Jectile constructed in accordance With the invention;
Fig. 2 is a similar fragmentary view illustrating a modification.
Referring to the drawing by characters of reference the projectile comprises a body 5, a neck "6 and a head I. The body part 5, which is preferwith a closed base 8 and with a chamber 9 open-- ing into the front face of the body and adapted to conveniently receive anexplosive charge I0. The body is formed with a reduced cylindrical front portion H providing annular shoulders l2 and I3.
The head part 1, which is preferebly of a metal such as aluminum having a low shear strength, has an ogival front end l4 and a reduced cylindrical rear end l providing an annular shoulder IS. The rear end I5 is formed with one or more rearwardly extending projections l'l-ll which are to serve as firing pins.
The neck part 5 which is preferably of a more rigid metal such as brass, is formed with front and rear cylindrical recesses respectively l8 and housed in the passage 2| and consists of a cup 23 having a flange 24 and carrying a priming charge 25. The flange 24 of the cup is seated on the annular shoulder 22 in position to be struck by the projections ll of the head.
When the projectile strikes an object the annular shoulder l6 of the head being seated on a rigid base is sheared or deformed and the head moves rearwardly relatively to the neck, the projections I9. The front recess l8 receives the rear end neck and on the floor of the recess I9. When thus assembled the neck constitutes a coupling between the head and the body and it is forwardly tapered to graduall merge the contours of the body and the ogival end ll of the head,
The recesses I8 and IQ of the neck are connected by a passage or recess 2| whose diameter approximates the diameter of the chamber 9 in the body and is less than the diameter of the front recess l8 to provide an annular counterbore shoulder 22. A commerciall obtainable percussion prim'enfor example a blank, cal. .22, is
ll striking the primer and serving as firing pins to ignite the priming charge and thereby set off the explosive charge. The sensitivity of the firing mechanism on impact will be dependent on the character, quality or strength of the metal at the shoulder H5. The metal on the line of shear or deformation may be strong or weak as occasion may require.
In the modification shown in Fig. 2 the major portion of the neck part 6 of Fig. 1 is combined with the body So and a washer to of a rigid metal to facilitate shearing forms a seat for the head la.
I claim:
1. A projectile comprising a body part having a reduced front end, an explosive charge in the body, a neck part force fitted on the reduced front end of the body, said neck part having a counterbored recess from its front end to the shoulder, a primer including a flanged cup inserted in the rear part of the-counterbored recess with its flange seated on the annular shoulder thereof, an ogival head part having a reduced portion force fitted in the front part of the counterbored recess in front of the primer and having a shearable shoulder seated on the front face of the neck part.
2. A projectile comprising a body part having a reduced front end, an explosive charge in the body, a neck part on the reduced front end of the body, said neck part having a counterbored recess from its front end to the front end of the body and providing an annular shoulder, a primer including a flanged cup inserted in the rear part of the counterbored recess with its flange seated on the annular shoulder thereof, an ogival head part having a reduced portion in the front part of the counterbored recess in front of the primer and having a shearable shoulder seated on the front face of the neck part.
3. A projectile comprising a body part of a relatively soft metal adapted to engage the rifling of a gun barrel, an explosive charge in the body part, a neck part of a more rigid metal assembled to the body part, a primer in said neck part, and a head of a metal having a low shear strength assembled to the neck part and adapted to serve as a firing pin on impact.
