FOLDABLE STAND FOR THREADING MACHINES Abstract of the Disclosure A foldable wheeled stand is provided for supporting a motor driven pipe threading machine during operation there- of, for transporting the machine from one location to anoth- er, and for storing the machine during periods of non-use. The stand includes an upper support portion on which the machine is mounted, and a scissors-type foldable leg assem- bly providing a lower support portion by which the upper support portion and threading machine can be elevated and lowered relative to an underlying support surface. Elevat- ing and lowering is achieved through a crank actuated jackscrew arrangement. The lower support portion includes a pair of wheels, whereby the stand, when folded, can be piv- oted relative to the wheels to an inclined angle at which the stand and the threading machine mounted thereon are sup- ported by the wheels for movement along the underlying sur- face. Further, the lower support portion includes a pair of skids which, when the stand is folded, facilitate sliding of the stand and the reading machine mounted thereon upwardly or downwardly relative to a fixed edge or edges above the underlying surface such as would be defined for example by stairs, or the edge of the bed of a truck relative to which the stand and machine are to be loaded or unloaded.
