Abstract
Abstract A valve cover for covering a buried valve and permitting access thereto with a two piece, rigid plastic housing having a square cross section which resists rotation in the ground. The housing is capped with a cast iron collar which fits inside the top end of the housing and has apertures in the portions engaging the housing walls through which the plastic extends to lock the collar to the housing. Adjacent the lower end of the housing are opposing apertures in the housing walls through which the pipes extend from the valve. A plurality of fingers extend outward from the housing about each aperture to form a tapering passage which will accommodate different sizes of pipes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A valve cover for covering a buried valve and permitting access thereto comprising: a hollow elongated housing member having opposed apertures adjacent one end thereof for each receiving a pipe section which extends therethrough with a valve between said sections being within said housing, a cast collar attached to and covering at the opposite end of said member for permitting access to said valve when said housing and valve are in place, and a plurality of flexible fingers each attached at one end to said housing about each of said apertures and extending outward therefrom to engage a pipe section to define a tapering passage for locking said valve and pipe sections securely to said cover.
Claim 2
Dependent Claim
116 words
A valve cover for covering a buried valve and permitting access thereto comprising: a hollow elongated housing member having opposed apertures adjacent one end thereof for each receiving a pipe section which extends therethrough with a valve between said sections being within said housing, a cast collar attached to and covering at the opposite end of said member for permitting access to said valve when said housing and valve are in place, and a plurality of flexible fingers each attached at one end to said housing about each of said apertures and extending outward therefrom to engage a pipe section to define a tapering passage for locking said valve and pipe sections securely to said cover.
Claim 3
Dependent Claim
25 words
A valve cover as in claim 1 wherein said housing member has to square cross section to prevent rotation of said cover in the ground.
Claim 4
Dependent Claim
15 words
A valve cover as in claim wherein said housing member is formed of rigid plastic.
Claim 5
Dependent Claim
15 words
