Abstract
A plastic shot shell wad incorporating an improved cushioning mechanism. A cushioning effect is provided by connecting a wad with a shot cup by means of two levels of parallel walls separated by an intermediate planar member. A lower level of walls is connected to a wad portion and an upper level of walls is connected to the shot cup portion. As a charge in a shotgun shell is ignited, the lower walls will be forced through the intermediate member, which provides a resistance which has a cushioning effect. As the lower walls move forward, they will become interleaved with the upper walls. By properly locating the upper and lower walls, tilting of the wad with respect to the shot cup after firing can be minimized.
Claims10
A unitary molded plastic wad for a shot shell comprising:
- a planar member having an upper and lower surface;
- at least one upper support wall extending substantially perpendicularly upwardly from said upper surface;
- a circular member having a generally planar end, wherein said end is connected to the top of said at least one upper support wall and is parallel to said planar member;
- at least one lower support wall extending substantially perpendicularly downwardly from said lower surface, wherein said upper and lower support walls lie in interleaved substantially parallel planes, wherein the total number of said upper and lower support walls is at least three and wherein the lower support wall lies in a plane adjacent to the plane of the upper support wall;
- a lower support disc which is parallel to the planar member and connected to the bottom of said at least one lower support wall, whereby when an upward force is applied to the lower support disc the planar member will deform and the upper and lower support walls will be forced into an interleaved arrangement, said lower support walls sliding into contact with said upper support walls, said interleaved arrangement thereby preventing pivoting between said upper and lower support walls.
