ABSTRACT:
Rotary power saw having plural saw wheels mounted on a turret and means to rotate the turret for presenting a particular saw wheel for sawing. A single drive means is provided, and means are provided for engaging it with a selected saw wheel for sawing, and disengaging it for changing the saw wheel selected for sawing. Thus, only the selected blade is driven, and only a single motor need be provided, yet the saw wheel can be changed easily and without tools.
In the preferred embodiment of the invention means are also provided for raising, lowering and tilting a selected saw wheel, so the present saw is as versatile as earlier saws having only a single blade.
