Pyramid projectile payload ejection device

DETAILED DESCRIPTION The general purpose of this invention is to provide an ejection or expulsion system for a payload projectile that has all the advantages of similarly employed prior art devices and has none of the above described disadvantages.
To attain this, the present invention provides a unique structural arrangement wherein the internal ogive portion of the projectile intermediate the rear primary payload and the expulsion charge cup is provided with a cup-like ejection member whose closed end faces the expulsion charge and peripheral wall conforms to the internal wall of the housing of the projectile with the forward open portion having an outwardly directed flange for sliding abutment with the inner projectile wall forward of the ogive.
The ejection member may be unitary wherein only one sealing "O" ring is required or partially open at its rear portion and closed by a pusher plate with two "O" rings for confining the gases generated by the expulsion charge.
The base of the projectile housing carries an internally extending stop member for terminating the rearward motion of the pusher assembly.
By filling the ejection member with an additional payload the previously empty ogive portion is thereby more fully utilized.
An object of the present invention is to provide a dispensing type payload projectile wherein a substantial portion of the ogive volume is utilized for cargo.
Another object is the provision of an efficient, low cost, high capacity projectile wherein the parasitic hardware is minimized and a simple pusher assembly is employed.
Still another object is to provide a direct pusher assembly for expulsion of the projectile payload including that portion situated within the projectile ogive.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings.
