Power tool with lightweight actuator housing
First Claim
1. A power tool assembly comprising:
- a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a portion of a shaping device supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion of the shaping device does not extend above the workpiece support surface;
an actuator housing configured to house a first actuating device at an active location at which a force from the first actuating device is transferred to the drop arm assembly when the drop arm assembly is at the first drop arm assembly position, the actuator housing including a slit configured to position a second actuating device at an inactive location; and
a control system configured such that when the first actuating device is housed, the control system controls the first actuating device to transfer the force to the drop arm assembly when an unsafe condition is sensed.

Abstract
A power tool assembly includes a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a portion of a shaping device supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion of the shaping device does not extend above the workpiece support surface, an actuator housing configured to house a first actuating device at an active location at which a force from the first actuating device is transferred to the drop arm assembly, the actuator housing including a slit configured to position a second actuating device at an inactive location, and a control system configured such that when the first actuating device is housed, the control system controls the first actuating device to transfer the force to the drop arm assembly when an unsafe condition is sensed.

15. A method of positioning an actuator in a power tool assembly including a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a portion of a shaping device supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion of the shaping device does not extend above the workpiece support surface, comprising:
-
positioning an end portion of a first actuator within an actuator housing configured to house the first actuating device at an active location at which a force from the first actuating device is transferred to the drop arm assembly when the drop arm assembly is at the first drop arm assembly position; inserting a bridge of a cartridge housing the first actuating device and a second actuating device into a slit extending from a first end portion of the actuator housing toward a second end portion of the actuator housing after positioning the end portion of the firs actuator within the actuator housing, the bridge extending between the first actuating device and the second actuating device; and seating the first actuator within the actuator housing. - View Dependent Claims (16, 17, 18, 19)
