Claims
- 1. A self-propelling, side-firing projectile comprising a projectile body having a solid forward nose portion and a rearward cylindrical, casing-forming portion, said casing-forming portion defining a chamber having an outer side wall with the base of said nose portion defining the forward end of said chamber and with the latter being opened at its rearward end, means for closing the rearward end of said chamber remote from said nose portion, a propellant charge provided in said chamber, there being a rearwardly annular recess in the base of said nose opening toward the forward end of said chamber remote from the rearward end thereof for communication with said chamber, the outer side of said recess being continuous with said chamber outer side wall whereby said recess is presented in the radially outward portion of said nose base, the inner side of said recess being constituted of a generally annular extension projecting rearwardly of said projectile from the said nose base and being radially inwardly of said outer side wall, said inner side of said recess being free at its nose remote end, a priming mixture disposed in said recess for ignition by side percussion through said outer side wall, said annular extension of said recess being outwardly turned in the rearward, free end portion thereof toward said recess outer side wall thereby relatively reducing the spacing between the same in the zone of direct communication with said propellant thereby effecting a compression of the priming mixture within the said recess.
- 2. A self-propelling, side-firing projectile as set forth in claim 1 wherein the nose portion and the case-forming portion are of one-piece construction.
- 3. A self-propelling side-firing projectile as set forth in claim 2 wherein the priming mixture recess is located spatially forwardly of the rearward extremity of said chamber and the outer side wall portion of said recess defines the zone of percussion.
