Waste discharge conduit support

Apparatus for supporting a conduit transporting fluent material in a predetermined direction of fluent material flow above a surface and for maintaining the conduit at an angle to a horizontal plane, said apparatus including a plurality of support units to be spaced from one another along a length of the conduit, said support units being of differing sizes and each support unit including at least one support member having an upper end and a lower end, said upper end positionable adjacent to and under the conduit and the lower end of the support member positionable at the surface, the sizes of the support units of said plurality of support units decreasing in the predetermined direction of fluent material flow through the conduit whereby transport of the fluent material through the conduit is caused by gravity, each support unit including a first support member having an upper end and a lower end, said upper end of said first support member positionable adjacent to and under the conduit and the lower end of said first support member positionable at the surface, a second support member having an upper end and a lower end, said upper end of said second support member positionable adjacent to and under the conduit next to the upper end of said first support member and the lower end of said second support member positionable at the surface, hinge means hingedly connecting said first and second support members at the lower ends thereof whereby the upper ends of said first and second support members can be moved toward or away from one another upon relative pivotal movement of said first and second support members at said hinge means, and lock means cooperable with said first and second support members for selectively locking said first and second support members against relative pivotal movement to retain the upper ends of said first and second support members a desired distance from one another, said lock means comprising a structural element extending between said first and second support members and interconnected to said first and second support members at locations between the upper ends and lower ends of said first and second support members, said structural element being releasably connected to at least one of said first and second support members whereby positioning of the structural element relative to at least one of said first and second support members can be changed to vary the length of said structural element positioned between the first and second support members and modify the distance between the upper ends of said first and second support members.
