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. The wheels are free to rotate about the axle. The swivel frame is rotatably mounted to the support structure. The foot portion of the jack means is disposed between the pair of wheels. When the frame has been moved to a predetermined location on the floor, the jack means is lowered until the foot portion contacts the floor and exerts enough pressure to remove the weight of the frame and the equipment from the castor wheels. The foot portion of the support structure includes a hole which is aligned with a hole in the floor. A bolt is passed through the hole in the floor and the hole in the foot portion to attach the frame firmly to the floor.
