Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
65 words
A pistol for determining design parameters for a handheld weapon comprising: 1. barrel means; 2. means for loading cartridges in said barrel means; 3. cartridge firing means; 4. grip means supporting said barrel means; and 5. adjustment means for changing the position of said grip means to positions ranging from directly behind the center of said barrel means to above and below said barrel means.
Claim 2
Dependent Claim
65 words
A pistol for determining design parameters for a handheld weapon comprising: 1. barrel means; 2. means for loading cartridges in said barrel means; 3. cartridge firing means; 4. grip means supporting said barrel means; and 5. adjustment means for changing the position of said grip means to positions ranging from directly behind the center of said barrel means to above and below said barrel means.
Claim 3
Dependent Claim
25 words
The pistol of claim 1 wherein said cartridge firing means comprises adjustable electronic firing control means for firing said cartridges at preselected rates of fire.
Claim 4
Dependent Claim
15 words
The pistol of claim 2 wherein said barrel means comprises a plurality of parallel barrels.
Claim 5
Dependent Claim
71 words
The pistol of claim 3 wherein said adjustable electronic firing control means comprises a plurality of capacitor discharge circuits for supplying electrical pulses to fire said cartridges, an adjustable frequency gated oscillator to sequentially supply pulses to discharge said capacitor discharge circuits, a trigger operated switch for gating said adjustable frequency gated oscillator to initiate firing; and a power supply means to charge said capacitor discharge circuits and power said oscillator.
Claim 6
Dependent Claim
34 words
The pistol of claim 4 wherein said cartridge firing means further comprises electrodes for grounding by way of said cartridges, said capacitor discharge circuits discharging to ground through said electrodes, thereby firing said cartridges.
Claim 7
Dependent Claim
48 words
The pistol of claim 4 wherein said adjustable electronic firing control means further comprises a plurality of binaries connected as a ring counter with the clock inputs of said binaries receiving said pulses from said gated oscillator and the outputs from said binaries driving said capacitor discharge circuits.
Claim 8
Dependent Claim
33 words
The pistol of claim 6 wherein the number of said parallel barrels, the number of said binaries connected as said ring circuit and the number of said capacitor discharge circuits are all equal.
Claim 9
Dependent Claim
41 words
The pistol of claim 1 wherein said adjustment means comprises a mating channel fixedly attached to the front of said grip means and a breech plate slidably mounted in said mating channel, said barrel means being attached to said breech plate.
Claim 10
Dependent Claim
47 words
The pistol of claim 8 wherein said means for loading cartridges comprises a pivot between said barrel means and said breech plate whereby said barrel means and said breech plate may be pivotally opened and a latch means for holding said breech plate and barrel means closed.
