ABSTRACT:
Herein is disclosed a portable and collapsible mounting for numerous types of power saw units, which comprises a table-like device having an open frame top with adjustable hanger brackets for rigidly securing the base of a power saw unit thereto. Said frame top is supported by forward and rearward pairs of legs rigidly braced in use, but pivotally connected at their upper ends with the frame for swinging inwardly against the said top frame to compact the assembly of saw unit and mounting. In the compact or collapsed position the assembly may be readily rolled from place-to-place or pushed upon a transportation vehicle through the medium of special enlarged wheels which are mounted on bolsters depending from the rear portion of the table top construction. At each end of the table top frame of the mounting a pair of roller-supporting rails are slidably and adjustably mounted in the longitudinal sides of the top frame. The outer ends of said pairs of rails are rigidly interconnected by a transverse crosspiece which in turn adjustably carries upstanding roller support rods which in turn, at their upper ends, carry a shaft and self-aligning roller bearings upon which a central roller is mounted. The said roller may thus be adjusted by set screws working against said rods for various horizontal positioning for horizontal alignment with the upper or work surface of the power saw unit or for positioning above or below such surface. Upon such rollers, where the roller rails are extended beyond the sides of the frame, elongate and relatively wide workpieces such as wall paneling, plywood, elongate planks and the like may be accommodated and guided as indicated in dotted lines in FIG. 2 and as shown in full lines in FIG. 3.
