Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
An integrated round comprising in combination: a unitary combustible cartridge of substantially uniform thickness having an axial cavity therein and an orifice at one end thereof, propellants contained in said cavity within said cartridge, a threaded collar having an integral neck and shoulder portion, which shoulder portion is inserted into said cavity through said orifice and is substantially complementary to the inner surface area of said cartridge surrounding said orifice, a coupling ring having threads complementary to said threads on said collar and having an endwall that is substantially complementary to the outer surface area of said cartridge surrounding said orifice, which coupling ring is threaded onto said neck of said collar, and a projectile having at one end thereof threads complementary to threads of said coupling ring, which projectile is threaded into said coupling ring.
Claim 2
Dependent Claim
136 words
An integrated round comprising in combination: a unitary combustible cartridge of substantially uniform thickness having an axial cavity therein and an orifice at one end thereof, propellants contained in said cavity within said cartridge, a threaded collar having an integral neck and shoulder portion, which shoulder portion is inserted into said cavity through said orifice and is substantially complementary to the inner surface area of said cartridge surrounding said orifice, a coupling ring having threads complementary to said threads on said collar and having an endwall that is substantially complementary to the outer surface area of said cartridge surrounding said orifice, which coupling ring is threaded onto said neck of said collar, and a projectile having at one end thereof threads complementary to threads of said coupling ring, which projectile is threaded into said coupling ring.
Claim 3
Dependent Claim
40 words
The round as defined in claim 1, wherein said threads on said collar are external threads on the neck of said collar, said threads on said coupling ring are internal threads, and said threads on said projectile are external threads.
Claim 4
Dependent Claim
32 words
The round as defined in claim 1 and further comprising a sealant in contact with said endwall of said coupling ring and said outer surface area of said cartridge surrounding said orifice.
Claim 5
Dependent Claim
26 words
The round as defined in claim 1, and further comprising in the wall of said cartridge surrounding said orifice, an axial slot opening into said orifice.
Claim 6
Dependent Claim
32 words
The round as defined in claim 4, wherein said cartridge is cylindrical, said orifice is circular and the rim of said shoulder on said collar defines a circle truncated on two sides.
Claim 7
Dependent Claim
19 words
The round as defined in claim 1, and further comprising a diaphragm across the aperature of said coupling ring.
Claim 8
Dependent Claim
46 words
The round as defined in claim 1, wherein said shoulder on said collar is substantially coextensive with the inner surface of said cartridge surrounding said orifice and said endwall on said coupling ring is substantially coextensive with the outer surface of said cartridge surrounding said orifice.
Claim 9
Dependent Claim
18 words
The round as defined in claim 1 and further comprising primers contained in said cavity within said cartridge.
Claim 10
Independent Claim
149 words
A method of forming an integrated round comprising: providing a unitary combustible cartridge of substantially uniform thickness having an axial cavity therein and an orifice at one end thereof, inserting a threaded collar having an integral neck and shoulder portion into said cavity through said orifice and causing said shoulder portion to remain in juxtaposition with the inner surface area of said cartridge surrounding said orifice and said neck of said collar to extend out of said cartridge through said orifice, threading a coupling ring having threads complementary to said threads on said collar onto said collar until the endwall of said coupling ring is in juxtaposition with the outer surface area of said cartridge surrounding said orifice, loading primers and propellants into said cavity of said cartridge, and threading onto said coupling ring a projectile having at one end thereof threads complementary to threads on said coupling ring.
Claim 11
Independent Claim
149 words
A method of forming an integrated round comprising: providing a unitary combustible cartridge of substantially uniform thickness having an axial cavity therein and an orifice at one end thereof, inserting a threaded collar having an integral neck and shoulder portion into said cavity through said orifice and causing said shoulder portion to remain in juxtaposition with the inner surface area of said cartridge surrounding said orifice and said neck of said collar to extend out of said cartridge through said orifice, threading a coupling ring having threads complementary to said threads on said collar onto said collar until the endwall of said coupling ring is in juxtaposition with the outer surface area of said cartridge surrounding said orifice, loading primers and propellants into said cavity of said cartridge, and threading onto said coupling ring a projectile having at one end thereof threads complementary to threads on said coupling ring.
Claim 12
Dependent Claim
27 words
The method as defined in claim 9 and further comprising the step of applying a sealant material to the outer area of said cartridge surrounding said orifice.
