Abstract
Abstract The invention pertains to a support for valves used in buried gas and water lines having curb boxes associated therewith to enable the valves to be manipulated from a remote point at ground level. A central cavity defined by the support receives the body of the valve. Extending in opposite directions from the central cavity are axially aligned outrigger portions for receiving the pipe ends connected to the valve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
In combination with a curb box, a valve support having opposed elongated and longitudinally spaced vertical side portions against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined in said support to receive a valve, connection cavities defined on opposite sides of said central cavity and partially defined by said side portions to receive the conduit lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align each said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
Claim 2
Dependent Claim
148 words
In combination with a curb box, a valve support having opposed elongated and longitudinally spaced vertical side portions against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined in said support to receive a valve, connection cavities defined on opposite sides of said central cavity and partially defined by said side portions to receive the conduit lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align each said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
Claim 3
Dependent Claim
190 words
In combination with a curb box, a valve support particularly designed for use with plastic lines used in the distribution of such fluids as gas and water and characterized by the protection of the lines from the torque of valve actuation and the upright support of the curb box, said valve support having opposed elongated and longitudinally spaced vertical side portions against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined in said support to receive a valve, connection cavities defined on opposite sides of said central cavity and partially defined by said side portions to receive the conduit lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
Claim 4
Dependent Claim
190 words
In combination with a curb box, a valve support particularly designed for use with plastic lines used in the distribution of such fluids as gas and water and characterized by the protection of the lines from the torque of valve actuation and the upright support of the curb box, said valve support having opposed elongated and longitudinally spaced vertical side portions against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined in said support to receive a valve, connection cavities defined on opposite sides of said central cavity and partially defined by said side portions to receive the conduit lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
Claim 5
Dependent Claim
196 words
In combination with a curb box, a valve support particularly designed for use with plastic lines used in the distribution of such fluids as gas and water and characterized by the protection of the lines from the torque of valve actuation and the upright support of the curb box, said valve support having outrigger portions in which the lines are adapted to be disPosed and against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined between said outrigger portion to receive the valve actuated through the curb box, cavities on opposite sides of said central cavity to receive the connections between the valve and the lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
Claim 6
Dependent Claim
196 words
In combination with a curb box, a valve support particularly designed for use with plastic lines used in the distribution of such fluids as gas and water and characterized by the protection of the lines from the torque of valve actuation and the upright support of the curb box, said valve support having outrigger portions in which the lines are adapted to be disPosed and against which the earth is adapted to be packed to resist the torque of valve actuation, said valve support being of open top construction throughout its entire longitudinal extent to permit a valve and associated conduit lines to be lowered into the support with the curb box removed, a central cavity defined between said outrigger portion to receive the valve actuated through the curb box, cavities on opposite sides of said central cavity to receive the connections between the valve and the lines, said curb box having a lower portion defining an arch embracing said central cavity, and means defining an interference fit between said arch and said support to align said arch with said central cavity and to brace said curb box normal to the longitudinal axis of said support.
