Abstract

Abstract A valve service box comprises an erect telescopic pipe structure whose sections made of plastic having resilient quality, are in frictional engagement. The upper end of the upper section has a collar holding a closure plate. The lower section is provided with two aligned diametrically opposite keyhole-shaped notches, starting from its lower rim edge, so that upon downward movement of said pipe structure in a trench or excavation leading to a sunken valve interposed in a gas or water pipeline, the valve''s inlet and outlet tubular members are entered in said notches respectively whereupon the lower pipe section is snapped on to the plumbing, thus anchoring said lower section against upward movement.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 124 words
A valve box comprising, a. at least one vertically elongated member having a generally axial passage open at the top and bottom, b. a hollow valve housing on the bottom of the elongated member, the housing being open at its bottom with the hollow interior thereof communicating with the passage in the elongated member, c. the housing having at least one opening in its side communicating with the bottom edge of the housing, the opening adapted to receive a pipe extending into said housing upon vertically downward movement of the housing, and d. means on the housing engageable with the pipe upon downward movement of the housing and after such engagement restraining separation of the housing and pipe upon upward movement of the housing.
Claim 2
Dependent Claim 124 words
A valve box comprising, a. at least one vertically elongated member having a generally axial passage open at the top and bottom, b. a hollow valve housing on the bottom of the elongated member, the housing being open at its bottom with the hollow interior thereof communicating with the passage in the elongated member, c. the housing having at least one opening in its side communicating with the bottom edge of the housing, the opening adapted to receive a pipe extending into said housing upon vertically downward movement of the housing, and d. means on the housing engageable with the pipe upon downward movement of the housing and after such engagement restraining separation of the housing and pipe upon upward movement of the housing.
Claim 3
Dependent Claim 25 words
A valve box comprising, a. the structure in accordance with claim 1 in which b. said means on the housing are defined by said opening.
Claim 4
Dependent Claim 29 words
A valve box comprising, a. the structure in accordance with claim 1 in which b. said means on the housing are a resiliently deflectable member extending into the opening.
Claim 5
Dependent Claim 38 words
A valve box comprising, a. the structure in accordance with claim 1 in which b. the said means on the housing are a constriction in the opening intermediate its top and bottom, the constriction being laterally resiliently deflectable.
Claim 6
Dependent Claim 41 words
A valve box comprising, a. the structure in accordance with claim 4 in which b. the said constriction is an integral part of the opening in the housing, the housing being sufficiently resilient to permit the constriction to resiliently deflect laterally.
Claim 7
Dependent Claim 27 words
A valve box comprising, a. the structure in accordance with claim 5 and b. an outwardly and downwardly flaring cam edge on the opening beneath the constriction.
Claim 8
Dependent Claim 28 words
A valve box comprising, a. the structure in accordance with claim 7 and b. an enlargement in the opening above the constriction to loosely receive the said pipe.
