Table saw with multiple blade turret
First Claim
1. A rotary table saw having mountings for plural saw wheels, a single saw wheel drive, and means to choose a particular saw wheel, comprising:
- A. a work support table having a slot therein;
B. a frame for supporting said work support table;
C. a turret carried on a pivot supported by said frame and disposed for rotation in a substantially vertical plane, whereby to present a selected saw wheel at said table slot by rotating said turret;
D. plural saw wheel arbor gears disposed circumferentially around said turret for being driven to rotate a corresponding saw wheel; and
E. drive means having a first position for driving the arbor gears of the saw wheel presented at said table slot during operation of said saw and a second position for disengaging said arbor gears during rotation of said turret for selection of another saw wheel, said drive means comprising;
i. a drive gear;
ii. a motor having an output shaft for driving said drive gear; and
iii. means to displace said motor and drive gear as a unit between said first position in which said drive gear meshes with the arbor gear of the saw wheel presented through said slot and said second position in which said drive gear is disengaged from said arbor gear, whereby only the saw wheel in use is driven during operation of the saw, and only one drive means is required for driving the selected saw wheel.

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.
