Abstract
Abstract An electrical generator for a self-contained electrically triggered weapon is provided which converts the reciprocating movement of a moving mechanical part of the weapon, e.g., a reciprocating breech member, into rotational movement of a generator rotor. A cam on the moving mechanical part engages in helical track to cause rotation thereof. This rotation is transmitted to the generator rotor through a gearing arrangement including a drive gear which drives the generator rotor during rotation of the track in a first direction, inertical forces providing for continued rotation of the generator rotor in the same direction during rotation of the track in the opposite direction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
An electrical generator for a self-contained electrically triggered weapon including a mechanical member which moves in translation, said generator including a rotor and mechanical means for converting the translational movement of the mechanical member into rotational movement of said rotor, said mechanical means comprising a shaft, means mounted on said shaft and defining a helical track for engaging a cam secured to the mechanical member so that said track defining means rotates responsive to translation of said mechanical member, a sector gear which rotates with rotation of said track defining means, and gear means including a drive gear for coupling said sector gear to the generator rotor.
Claim 2
Dependent Claim
107 words
An electrical generator for a self-contained electrically triggered weapon including a mechanical member which moves in translation, said generator including a rotor and mechanical means for converting the translational movement of the mechanical member into rotational movement of said rotor, said mechanical means comprising a shaft, means mounted on said shaft and defining a helical track for engaging a cam secured to the mechanical member so that said track defining means rotates responsive to translation of said mechanical member, a sector gear which rotates with rotation of said track defining means, and gear means including a drive gear for coupling said sector gear to the generator rotor.
Claim 3
Dependent Claim
44 words
A generator as claimed in claim 1 wherein said cam is affixed to a stop which is integral with said mechanical member, said track defining means being mounted for rotation on said shaft and said sector gear being secured to said track defining means.
Claim 4
Dependent Claim
40 words
A generator as claimed in claim 1 wherein said gearing means includes first and second oppositely acting drive gears for alternately driving said rotor in the same direction responsive to respective translational movements of the mechanical member in opposite directions.
Claim 5
Dependent Claim
45 words
A generator as claimed in claim 3 wherein said gearing arrangement further includes a first pinion mounted on said rotor and drivenly coupled to said first drive gear and a second pinion coupled to said first pinion and drivenly coupled to said second drive gear.
Claim 6
Dependent Claim
49 words
A generator as claimed in claim 1 wherein said drive gear includes a plurality recesses equally spaced about the periphery thereof for receiving a corresponding roller member therein, each said recess including a wedging face and a bearing face at an obtuse angle with respect to said wedging face.
Claim 7
Dependent Claim
14 words
A generator as claimed in claim 5 wherein said roller member comprises spherical bearing.
Claim 8
Dependent Claim
15 words
A generator as claimed in claim 5 wherein said roller member comprises a cylindrical roller.
