Abstract

A table saw apparatus including an extendable table. The table saw also includes a rip fence with a constant alignment spring finger to ensure alignment at all times between the rip fence and the table saw blade. The table saw further includes a self-adjusting rip fence scale associated with the extending portion of the table. The table saw further includes a self-aligning blade guard that, once adjusted a first time, ensures alignment between the blade guard and the blade on any subsequent installations of the guard. The table saw also includes a novel cradle assembly for elevating and beveling the blade.

Claims

1. A table saw comprising:

a base;

a first table mounted to the base, wherein the first table has a work support surface defining a plane;

a saw blade operably supported by the base and extendable through the work support surface;

a second table;

first and second rails having first and second ends, wherein the rails are slidably mounted to the first table and the second ends are rigidly mounted to the second table such that the second table is slidably movable relative to the first table;

a locking mechanism connected to at least one of the first or second table, the locking mechanism including a locked position in which the second table is locked relative to the first table, and an unlocked position in which the second table is movable relative to the first table; and

the locking mechanism including a lever that extends from the plane of the work support surface to a work support side of the plane when in the unlocked position to obstruct the use of the table saw.

2. The table saw according to claim 1, wherein the locking mechanism secures the second table in any position relative to the first table within a set of predetermined limits of travel.

3. The table saw according to claim 2, wherein the locking mechanism comprises means for applying equal locking pressure to the first and second rails.

4. The table saw according to claim 2, wherein the locking mechanism comprises a cam positioned in a free floating bushing.

5. The table saw according to claim 4, wherein the lever is connected to the cam, and wherein the cam is connected to opposing first and second clamping rods, the clamping rods being engagable with the first and second rails to lock the second table in any position relative to the first table when the lever is in a locked position.

6. The table saw according to claims 4, wherein the first table defines a second surface opposite the work support surface, and wherein the locking mechanism is attached to the second surface.

7. The table saw according to claim 1, wherein at least one carrying handle is formed into the first table to facilitate the portable transport of the table saw.

8. The table saw according to claim 1, wherein the lever lies generally within the plane of the work support surface in the locked position.

9. A table saw comprising:

a base;

a first table mounted to the base, wherein the first table includes a work support surface defining a plane;

a saw blade operably supported by the base and extendable through the first work support surface;

a second table operably connected to the first table and movable relative to the first table;

a locking mechanism connected to at least one of the first or second table, the locking mechanism having locked and unlocked positions, wherein the locked position fixes the second table relative to the first table, and the unlocked position allows the second table to move relative to the first table; and

the locking mechanism including a lever that extends from the plane of the first work support surface to a work support side of the plane when in the unlocked position to obstruct the use of the table saw.
