TABLE SAW WITH LINKAGE DROP SYSTEM
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 link arm with a first tracking component and a first slot, the first tracking component slidingly engaged with the swing arm assembly;
a second link arm with a second tracking component engaged with the first slot;
an actuator configured to pivot the second link arm from a first position whereat force from the first link arm acting on the tracking component is directed at a second link arm pivot toward a second position whereat force from the first link arm acting on the tracking component is not directed at the second link arm pivot; and
a control system configured to actuate the actuator in response to a sensed condition.

8. A table saw comprising:
-
a work piece support surface; a swing arm movable along a swing arm path from a first swing arm position whereat an arbor shaft rotatably supported by the swing arm is positioned proximate to the work piece support surface and a second swing arm position whereat the arbor shaft is distal to the work piece support surface; a first link arm with a first tracking component and a first slot, the first tracking component slidingly engaged with the swing arm; a second link arm with a second tracking component engaged with the first slot; an actuator configured to pivot the second link arm from a first position whereat the first link arm and the second link arm form an angle of between about 80 degrees and about 100 degrees to a second position whereat the first link arm and the second link arm do not form an angle of between about 80 degrees and about 100 degrees; a control system configured to actuate the actuator in response to a sensed condition. - View Dependent Claims (9, 10, 11, 12, 13, 14)
