ABSTRACT:
An upright frame or standard supports a canvas tray holder attached to a continuous endless V-belt stretched between two pulleys. A counterbalanced weight is attached to hold the canvas tray holder and workpiece in equilibrium, and is readily adjustable to any working height. The standard is mounted on a rectangular horizontal base frame with casters. It is supported vertically by an inclined cross brace assembly connected at pivot points to the standard and at holes on the horizontal base frame members for a vertical or an inclined position of the standard.
