TABLE SAW WITH PRESSURE OPERATED ACTUATOR
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 latch pin movable between a first position whereat the latch pin is engaged with the swing arm assembly and a second position whereat the latch is not engaged with the swing arm assembly;
a pressure operated actuator configured to force the latch pin from the first position to the second position and to force the swing arm assembly away from the first swing arm position and toward the second swing arm position; and
a control system configured to actuate the actuator in response to a sensed condition.

6. A power tool, comprising:
-
a latch hold mechanism; a swing arm movable along a swing arm path between an upper first swing arm position and a lower second swing arm position; a latch pin supporting the swing arm in the first swing arm position; pressure operated actuator configured to transfer a first force to the swing arm sufficient to move the swing arm from the first swing arm position toward the second swing arm position; and a control system configured to control the actuating device. - View Dependent Claims (7, 8, 9, 10)

11. A table saw comprising:
-
a work piece support surface; a shaping device support shaft automatically retractable along a retraction path from a first shaft position to a second shaft position in response to a sensed condition, wherein the second shaft position is more distal to the work piece support surface than the first shaft position; a latch pin movable between a first latch pin position whereat the shaping device support shaft is maintained at the first shaft position and a second latch pin position whereat the shaping device support shaft is not maintained at the first shaft position; a pressure operated actuator; and a control system configured to cause the pressure operated actuator to generate a force causing the latch pin to move from the first latch pin position toward the second latch pin position in response to a sensed condition. - View Dependent Claims (12, 13, 14, 15)
