Abstract:
1. Circular saw apparatus usable both as a miter saw and as a table saw, comprising: a base frame; a rear mounting pedestal to the rear end of the base frame; a lower, miter saw table rotatably mounted on the base frame for swivelling movement about a vertical axis, said miter saw table having a lower saw slot for receiving a circular saw blade; a circular saw assembly having a saw blade and motor combination pivotally mounted on said rear mounting pedestal for pivoting relative thereto about a horizontal axis, the miter saw table providing a turntable for the circular saw assembly; handle means for adjusting the swivel position of said miter saw table and for moving said circular saw about said horizontal axis so that said saw blade can move into and out of said lower saw slot; a workpiece back guide fixedly mounted on said base frame for positioning a workpiece on said miter saw table and located behind said vertical axis of the miter saw table so that the circular saw can be used in miter saw mode, upon adjustment of the swivel position of the miter saw table, by downwards movement of the circular saw blade into said lower saw slot by manipulation of said handle means; an upper saw table having a second saw slot aligned with said saw blade and pivotally connected to a rear portion of said base frame for movement about a horizontal axis between a raised position in which said upper saw table is clear of the circular saw assembly when said saw assembly is to be used in miter saw mode, and a lowered, generally horizontal position in which said saw blade protrudes from said second saw slot in said upper saw table when said saw assembly is to be used in table saw mode.
