Abstract: An adjustable support for a display terminal is provided which comprises a novel moulded base element having a pair of concave tracks in the top and an annular recess in the bottom. The concave tracks in the top of the base are adapted to receive and support a moulded cradle element which serves as a housing for the CRT display. The annular recess in the bottom of the base receives an annular support ring which is adapted to support the base and the cradle. The three moulded elements are designed to fit together and maintain contact with each other by gravity so as to provide a low cost accurate adjustable support.

Abstract: A combination dual wheel castor and jack combination assembly is disclosed. The assembly comprises a support structure having a nut-like portion and elongated portions attached to the nut-like portion. The elongated portions extend from the nut-like portion in opposite directions. The support structure includes a hole passing through at least one of the elongated portions and the nut-like portion. The hole is internally threaded along at least a portion of its length. A jack means comprising an elongated threaded shaft portion and a foot portion rotatably mounted to one end of said shaft portion is adapted to be threaded into the hole in the support structure. By gripping and turning the nut-like portion of the support structure, the shaft portion of the jack means is caused to move relative to the support structure in one direction or the other. A castor portion of the assembly comprises a pair of wheels which are spaced apart and attached to a swivel frame by an axle.
