Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
A pipe joint comprising a first tubular member having a ball portion, a second tubular member having a socket portion which receives therein said ball portion, said socket portion being formed with a pair of substantially diametrically located openings overlying outwardly curved spaced segments of the received ball portion, and a resilient clip spring having inwardly curved end portions extending through said openings into engagement with said outwardly curved spaced segments of said ball portion urging said ball portion against said socket portion and thereby provide a sealing relationship between said ball and socket portions.
Claim 2
Dependent Claim
95 words
A pipe joint comprising a first tubular member having a ball portion, a second tubular member having a socket portion which receives therein said ball portion, said socket portion being formed with a pair of substantially diametrically located openings overlying outwardly curved spaced segments of the received ball portion, and a resilient clip spring having inwardly curved end portions extending through said openings into engagement with said outwardly curved spaced segments of said ball portion urging said ball portion against said socket portion and thereby provide a sealing relationship between said ball and socket portions.
Claim 3
Dependent Claim
32 words
A pipe joint in accordance with claim 1 in which said socket portion has a cylindrical end portion overlying said outwardly curved segments, said openings being located in said cylindrical end portion.
Claim 4
Dependent Claim
16 words
A pipe joint in accordance with claim 2 in which said openings constitute circumferentially arranged slots.
Claim 5
Dependent Claim
52 words
A pipe joint in accordance with claim 1 in which the intermediate portion of said clip spring extending between its ends has a curvature of a larger radius than that of said socket portion so as to provide a spaced relationship between said spring and the exterior of said cylindrical end portion.
Claim 6
Dependent Claim
33 words
A pipe joint in accordance with claim 4 in which said openings constitute elongated slots and the end portions of said spring have substantially the same thickness as the width of said slots.
