Abstract
Abstract In a Gatling gun containing a rotary weapon barrel assembly and positively reciprocating breechblocks, each of which is operatively associated with one weapon barrel of the weapon barrel assembly, each breechblock is provided with a spring-loaded firing pin and a cocking pin which are cocked and released by two control cams for piercing a cartridge. These two control cams are displaced from a safety or unarmed position into a firing position by a control slide possessing oppositely extending control grooves or slots. This firing apparatus possesses no pivotable parts as opposed to known apparatuses.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A firing apparatus for firing a cartridge in an externally powered firing weapon containing at least one revolving weapon barrel, comprising: a reciprocatable breechblock operatively associated with said at least one revolving weapon barrel; means for positively reciprocating said breechblock relative to said at least one revolving weapon barrel; a spring-loaded firing pin displaceably mounted in said breechblock; two displaceable control cams for cocking and releasing said firing pin in order to pierce said cartridge; displacing means for displacing said two displaceable control cams from an unarmed position into a firing position; said displacing means containing a control slide provided with two control grooves extending in opposite directions; a spring operatively connected to said control slide and urging said control slide into an unarmed position of said control slide; and said displacing means containing hydraulic piston means acting upon said control slide in order to displace said control slide into a firing position of said control slide and against the force of said spring.
Claim 2
Dependent Claim
164 words
A firing apparatus for firing a cartridge in an externally powered firing weapon containing at least one revolving weapon barrel, comprising: a reciprocatable breechblock operatively associated with said at least one revolving weapon barrel; means for positively reciprocating said breechblock relative to said at least one revolving weapon barrel; a spring-loaded firing pin displaceably mounted in said breechblock; two displaceable control cams for cocking and releasing said firing pin in order to pierce said cartridge; displacing means for displacing said two displaceable control cams from an unarmed position into a firing position; said displacing means containing a control slide provided with two control grooves extending in opposite directions; a spring operatively connected to said control slide and urging said control slide into an unarmed position of said control slide; and said displacing means containing hydraulic piston means acting upon said control slide in order to displace said control slide into a firing position of said control slide and against the force of said spring.
Claim 3
Dependent Claim
174 words
A firing apparatus for firing a cartridge in an externally powered firing weapon containing at least one revolving weapon barrel, comprising: a reciprocatable breechblock operatively associated with said at least one revolving weapon barrel; means for positively reciprocating said breechblock relative to said at least one revolving weapon barrel; a spring-loaded firing pin displaceably mounted in said breechblock; two displaceable control cams for cocking and releasing said firing pin in order to pierce said cartridge; displacing means for displacing said two displaceable control cams from an unarmed position into a firing position; said displacing means containing a control slide provided with two control grooves extending in opposite directions; said control slide extending in a predetermined direction; each one of said two control grooves containing a central section which is inclined relative to said predetermined direction of extent of said control slide; and each one of said two control grooves further containing substantially straight sections at related ends of said control groove and extending substantially in said predetermined direction of extent of said control slide.
Claim 4
Dependent Claim
174 words
A firing apparatus for firing a cartridge in an externally powered firing weapon containing at least one revolving weapon barrel, comprising: a reciprocatable breechblock operatively associated with said at least one revolving weapon barrel; means for positively reciprocating said breechblock relative to said at least one revolving weapon barrel; a spring-loaded firing pin displaceably mounted in said breechblock; two displaceable control cams for cocking and releasing said firing pin in order to pierce said cartridge; displacing means for displacing said two displaceable control cams from an unarmed position into a firing position; said displacing means containing a control slide provided with two control grooves extending in opposite directions; said control slide extending in a predetermined direction; each one of said two control grooves containing a central section which is inclined relative to said predetermined direction of extent of said control slide; and each one of said two control grooves further containing substantially straight sections at related ends of said control groove and extending substantially in said predetermined direction of extent of said control slide.
Claim 5
Dependent Claim
37 words
The firing apparatus as defined in claim 2, wherein: said central sections of said two control grooves are oppositely inclined relative to each other and with respect to said predetermined direction of extent of said control slide.
