Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
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.
Claim 2
Dependent Claim
159 words
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.
Claim 3
Dependent Claim
167 words
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.
Claim 4
Dependent Claim
167 words
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.
Claim 5
Dependent Claim
35 words
The apparatus of claim 2, wherein said ram member is provided with a second groove adjacent the side of the first groove opposite the transverse bore, and a sealing ring disposed in said second groove.
Claim 6
Dependent Claim
44 words
The apparatus of claim 2, wherein said body is provided with a wall at the end of said longitudinal bore opposite the end adapted to receive a pyrotechnic device, said wall constituting means to stop the motion of said ram at said second position.
Claim 7
Dependent Claim
27 words
The apparatus of claim 4, wherein said wall is provided with an orifice adaped for admission of a tool for adjusting said ram to its initial position.
