WAD
Filed Jan. 29, 1968 IN VENTOR.
United States Patent Filed Jan. 29, 1968, Ser. No. 701,306 Claims priority, application Italy, Feb. 27, 1967, 13,115/ 67 Int. Cl. B42b 7/08 US. Cl. 102-95 2 Claims ABSTRACT OF THE DISCLOSURE The wad according to this invention comprises a first component shaped as a cylindrical capsule (1040') fitting a second component shaped as a chalice (1), the bottom (2) of the said chalice being adjacent to the small shots (3) and the cylindrical capsule (10-10) abutting by a side against a powder container (11) and by the opposite side presenting a recess (20) fitting the abutting rim of the chalice (1) so as to obtain during the cartridge deflagration a high expansion and recoil force absorption coefficient.
This invention is concerned with improvements in the structure of wads as used particularly for shot-gun cartridge-eases. Such improvements aim to provide a substantial simplification in their manufacture and to increase their efficiency.
Two embodiments of the invention will be now illustrated with reference to the annexed drawing, wherein:
FIG. 1 is an elevational section view of a cartridge case embodying a wad according to this invention;
FIG. 2 is a representation similar to FIG. 1 showing a further embodiment of a wad according to this invention;
FIG. 3 is an elevational sectional view of the wad itself;
FIG. 4 is an elevational sectional view of a first embodiment of the wad capsule; and
FIG. 5 is a representation similar to FIG. 4 of a second embodiment of the wad capsule with the wad fitted therein.
The wad according to the invention is constituted as a body 1 of plastic material presenting in cross-section the shape of a chalice with a bottom 2 slightly convex and adjacent to the small shot 3. The lateral wall of the wad is slidably mounted with a little play along the cylindrical wall of a cylindrical capsule 10.
3,503,332 Patented Mar. 31, 1970 ice The cylindrical capsule 10 has a disc-shaped bottom 5 abutting against a step formed by the powder container 11 and receives the whole wad as shown. A recess 20 is formed at the bottom 5 of the capsule for receiving the chalice rim so that a collapsible mounting of the wad wall is prevented.
According to the modification in FIGURES 2 and 5 the lateral wall of the capsule 10' is prolonged by a number of wings (6), that are (as shown) initially cut or formed with tear lines so as to contain the small shots.
OPERATION As soon as the powder is exploded as a consequence of the reaction of the small shot (3) an expansion results in the chalice-shaped wall 4 and therefore it is possible to obtain a very high efiiciency for the gases produced during the deflagration.
What I claim is:
1. Wadding for a shot-gun shell filled with small shot comprising a first and a second component each constituted of an easily deformable substance, the first component being a hollow body of rotation having a chalice shape, said body including a bottom, a stem-shaped portion connected to said bottom and an arc-shaped profiled hollow body portion branching from said stem-shaped portion, said second component including a substantially discshaped portion, said arc-shaped hollow body portion having a rim abutting against the disc-shaped portion of the second component so as to define therebetween an enclosed air cushion to promote a radial expansion only of the hollow body during cartridge defiagration.
2. Wadding according to claim 1, wherein the said second component is cylindrical and said disc-shaped portion forms the bottom thereof, said bottom being formed with an annular groove, said n'm fitting into said annular groove.
