Abstract
Abstract The automatic weapon has a compression chamber with a power outlet port aligned with a reciprocating barrel and an intake port aligned with a carburetor. A belt carrying a plurality of projectiles is fed between the reciprocating barrel and the power outlet port. A shaft driven rotor and vane are offset positioned within the compression chamber. The barrel, belt and rotor are synchronized so that carbureted fuel is compressed and ignited when the barrel has forced the belt to sealably engage the power outlet port with a projectile positioned in the barrel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
A liquid fuel operated automatic weapon including: A. a compression chamber having an intake port and a power outlet port; B. a carburetor means connected to the intake port to supply carbureted fuel thereto; C. compression means within the compression chamber to place the carbureted fuel in a compressed state in the area of the power outlet port; D. ignition means cooperating with the chamber to fire the carbureted fuel; E. reciprocating barrel means positioned in operational alignment with the power outlet port; F. belt means having a plurality of aligned projectiles secured thereto; G. feed means connected to the belt means to feed the belt between the barrel and the power outlet port; and H. synchronizing means connecting to the barrel and the feed means to position a projectile in line with the power outlet port and the barrel against the belt means to sealably engage the power outlet port when the ignition means fires.
Claim 2
Dependent Claim
156 words
A liquid fuel operated automatic weapon including: A. a compression chamber having an intake port and a power outlet port; B. a carburetor means connected to the intake port to supply carbureted fuel thereto; C. compression means within the compression chamber to place the carbureted fuel in a compressed state in the area of the power outlet port; D. ignition means cooperating with the chamber to fire the carbureted fuel; E. reciprocating barrel means positioned in operational alignment with the power outlet port; F. belt means having a plurality of aligned projectiles secured thereto; G. feed means connected to the belt means to feed the belt between the barrel and the power outlet port; and H. synchronizing means connecting to the barrel and the feed means to position a projectile in line with the power outlet port and the barrel against the belt means to sealably engage the power outlet port when the ignition means fires.
Claim 3
Dependent Claim
41 words
The automatic weapon of claim 1 wherein the compression means includes a shaft driven rotor offset positioned adjacent an interior compression chamber wall and an adjustable vane cooperating with the rotor and the chamber wall to compress the carbureted fuel therebetween.
Claim 4
Dependent Claim
40 words
The automatic weapon of claim 2 wherein the rotor has a slideway therethrough and the vane is positioned in the slideway, said vane being extensible to sealably engage the chamber wall at both ends of the vane at all times.
Claim 5
Dependent Claim
27 words
The automatic weapon of claim 3 wherein the extensible vane includes a spring loaded outer section which is continually forced outward to sealably engage the chamber wall.
Claim 6
Dependent Claim
18 words

Claim 7
Dependent Claim
46 words
The automatic weapon of claim 2 wherein the belt means includes a plurality of aligned holes which frictionally engage the projectiles to secure them thereto, said projectiles having a cone-shaped forward section and a flanged rearward section to maintain the projectile on the belt normal thereto.
Claim 8
Dependent Claim
26 words
The automatic weapon of claim 2 wherein the feed means includes a drive sprocket and an idler sprocket positioned on opposing sides of the belt means.
Claim 9
Dependent Claim
46 words
The automatic weapon of claim 2 wherein the synchronizing means includes two cams positioned on the shaft which rotates the rotor, one cam connecting to the barrel to cause reciprocation thereof and the other cam connecting to the feed means as part of a timing linkage.
Claim 10
Dependent Claim
24 words
The automatic weapon of claim 2 wherein a motor means connects to the shaft, said motor means including a clutch to engage the shaft.
Claim 11
Dependent Claim
25 words
