Abstract

A table saw includes a table disposed on a housing, a plate supported in the housing, a follower rotatably secured to the plate with a pivot axle, a saw blade rotatably secured to the follower with a pole and rotated in concert with the follower relative to the plate. A motor is coupled to the pole, with a pulley-and-belt coupling or the like, for driving the saw blade via the pole. A threaded shaft is engaged with a gear sector of the follower for rotating the follower relative to the plate and for moving the saw blade upward and downward relative to the table.

Claims

1. A table saw comprising:

a housing including a table provided on top thereof,

a plate supported in said housing,

a follower rotatably secured to said plate with a pivot axle,

a saw blade rotatably secured to said follower with a pole and rotated in concert with said follower relative to said plate,

means for driving said pole to rotate and to drive said saw blade, and

means for rotating said follower relative to said plate about said pivot axle to move said saw blade upward and downward relative to said table.

2. The table saw according to claim 1, wherein said pole driving means includes a motor secured to said follower and having a spindle, and means for coupling said spindle to said pole.

3. The table saw according to claim 2, wherein said coupling means includes a first pulley secured on said pole and rotated in concert with said pole, a second pulley secured on said spindle and rotated in concert with said spindle, and a belt engaged around said first and said second pulleys.

4. The table saw according to claim 3, wherein said motor includes a panel extended therefrom and having a curved groove formed therein, a fastener engaged through said curved groove of said panel and secured to said follower for adjustably securing said motor to said follower at a selected angular position.

5. The table saw according to claim 2, wherein said follower includes a channel formed therein for receiving said spindle of said motor.

6. The table saw according to claim 2, wherein said plate includes a cavity formed therein for receiving said spindle of said motor.

7. The table saw according to claim 1, wherein said follower rotating means includes a sector gear formed in said follower, a shaft rotatably secured to said plate and having a threaded portion engaged with said sector gear of said follower in order to rotate said follower relative to said plate when said shaft is rotated relative to said plate.
