Abstract
A table support of die-cast and machined generally wedge-shaped configuration is suspended from the machine base by four screws and positioned by four leveling screws adjacent the suspension screws. The table support provides two parallel, spaced apart flat, inclined ramps or ways along which the in-feed table is moved by a height adjustment screw. The in-feed table is also of die-cast and machined generally wedge-shaped configuration and is held to the table support by a pair of extension coil springs having looped ends that are inserted into holes provided in the table and table support castings, respectively, so that the assembly is of generally rectangular block shape of variable height. In assembly, the springs are assembled in a relatively unstressed position and the table and table support moved relative one another by pushing the table up the ramps or ways on the table support to stretch and tension the springs to tighten the table and table support together. A hook on the table rides over a lug on the table support when the springs are stretched to lock the unit or assembly together.
