Abstract
An interlocking jack stand has right and left sides of complementary configuration, each supplying two legs of a four-legged stand. Each side is of a sheet material with a semi-circular corner portion merging with legs in right angular relationship and tapered in breadth so as to be wide at the bottom and narrow at the top. The material of one side has slots extending up from the bottom and material of the other side has slots extending down from the top. Slots are respectively at the junction of the semi-circular corner with the legs for one side and part way around the semi-circular corner of the other side so that when the sides are slid together in interlocked relation there is a circular hollow central column partially of double wall thickness in which a vertically adjustable screw support is mounted.
