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.
