Claims5
Apparatus for discharging a gas bottle, comprising:
- (a) a tubular body provided with a transversely facing orifice adapted to receive the neck of a gas bottle,
- (b) a ram member slidably disposed inside said body and provided with a transverse bore adapted to receive the end of the neck of the gas bottle, said ram member being initially positioned with said bore aligned with said orifice, and
- (c) a pyrotechnic device secured within one end of the body member, and adapted, when fired, to drive said ram lengthwise to a second position, shearing off the neck of the bottle and carrying the end;
- in said transverse bore,
- (d) said ram member being provided with a circumferential groove which, when said ram is in said second position, lies under said transversely facing orifice in said body,
- (e) said body being provided with at least one further orifice that opens into said groove when said ram is in said second position.

Apparatus for discharging a gas bottle, comprising:
- (a) a body provided with a longitudinal bore and a transversely facing orifice into said bore adapted to receive the neck of a gas bottle, and
- (b) a ram member slidably disposed in said longitudinal bore and provided with a transverse bore adapted to receive the end of the neck of the gas bottle, said ram member being initially positioned with said transverse bore aligned with said orifice,
- (c) one end of said longitudinal bore being adapted to receive a pyrotechnic device for driving, when fired, said ram to a second position, shearing off the neck of the bottle and carrying the end thereof in said transverse bore,
- (d) said ram member being provided with a peripheral groove which, when said ram is in said second position, lies under said transversely facing orifice in said body,
- (e) said body being provided with at least one further orifice that opens into said groove when said ram is in said second position.
