Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
