Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
A subassembly for crimping a first conduit having a flared end portion onto a second conduit partially inserted into the flared end portion of the first conduit, which comprises; a. a chamber having first and second ends adapted to fit over the area of insertion between the first and second conduits; b. a die reciprocally mounted in and confined by the chamber, said die encircling the first conduit adjacent its flared end portion; c. propellant means for driving the die longitudinally over the flared end portion and compressing said portion radially inwardly, said propellant means positioned between the die and the first end of said chambers; d. detonating means for detonating the propellant means; and e. a malleable, annular cap positioned on the second conduit between the flared end portion of the first conduit and the second end of the chamber, said cap capable of being radially deformable by said die upon detonation of the propellant means.
Claim 2
Dependent Claim
157 words
A subassembly for crimping a first conduit having a flared end portion onto a second conduit partially inserted into the flared end portion of the first conduit, which comprises; a. a chamber having first and second ends adapted to fit over the area of insertion between the first and second conduits; b. a die reciprocally mounted in and confined by the chamber, said die encircling the first conduit adjacent its flared end portion; c. propellant means for driving the die longitudinally over the flared end portion and compressing said portion radially inwardly, said propellant means positioned between the die and the first end of said chambers; d. detonating means for detonating the propellant means; and e. a malleable, annular cap positioned on the second conduit between the flared end portion of the first conduit and the second end of the chamber, said cap capable of being radially deformable by said die upon detonation of the propellant means.
Claim 3
Dependent Claim
36 words
The subassembly of claim 1 wherein said die includes an inner leading surface convexly shaped so that said die may form a cold cylindrical bead on said flared end portion upon detonation of said propellant means.
