TABLE SAW WITH RATCHET MECHANISM
First Claim
1. A table saw comprising:
- a work-piece support surface;
a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface;
a first ratchet member operatively connected to the swing arm assembly; and
a second ratchet member movable between a first ratchet position whereat rotation of the first ratchet member in a first and a second direction is allowed, and a second ratchet position whereat the second ratchet member is engaged with the first ratchet member such that rotation in only the first direction is allowed.

Abstract
A table saw in one embodiment includes a work-piece support surface, a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface, a first ratchet member operatively connected to the swing arm assembly, and a second ratchet member movable between a first ratchet position whereat rotation of the first ratchet member in a first and a second direction is allowed, and a second ratchet position whereat the second ratchet member is engaged with the first ratchet member such that rotation in only the first direction is allowed.

9. A table saw comprising:
-
a work-piece support surface; a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface; an actuating device configured to transfer a force to the swing arm assembly to accelerate the swing arm assembly in a direction toward the second swing arm position; a control system configured to control the actuating device; a first ratchet member positioned on a swing arm assembly housing; and a second ratchet member movable between a first ratchet position whereat rotation of the first ratchet member in a first and a second direction is allowed, and a second ratchet position whereat the second ratchet member is engaged with the first ratchet member such that rotation in only the first direction is allowed. - View Dependent Claims (10, 11)
