Abstract:
In at least one illustrative embodiment, a winch may include first and second end frames, a drum coupled between the first and second end frames and configured to rotate to wind or unwind a cable, a brake configured to resist rotation of the drum when engaged, a switch configured to cause the brake to engage the drum when the switch is activated, a slack arm frame having a first end engaged with the cable and a second end pivotally coupled between the first and second end frames, where the slack arm frame is configured to pivot between a first position when the cable is taut and a second position when the cable is slack, and a cam coupled to the slack arm frame and configured to rotate with the slack arm frame to activate the switch when the slack arm frame is in the second position.

Claim (Index 1):
A winch comprising:\n a first end frame and a second end frame; a drum located between and rotatably coupled to_the first and second end frames and configured to rotate to wind or unwind a cable; a brake configured to resist rotation of the drum when engaged; a switch configured to cause the brake to engage the drum when the switch is activated; a slack arm frame engaging the cable and including a first lever arm and a second lever arm, the first lever arm pivotally coupled to the first end frame and the second lever arm pivotally coupled to the second end frame, wherein the slack arm frame is configured to pivot between a first position when the cable is taut and a second position when the cable is slack; a cam having an arcuate camming surface coupled to the slack arm frame and the first end frame, with the first end frame located between the slack arm frame and the cam; a mounting bracket coupling the switch to the first end frame, wherein the mounting bracket is adjustable between a plurality of locations on the first end frame by loosening and tightening a single fastener, each of the plurality of locations positioning the switch at a different distance from the axis; a first drop stop attached to the first lever arm and extending toward the first end frame, the first drop stop being configured to directly contact the first end frame when the slack arm frame pivots from the first position to the second position to prevent further pivoting of the slack arm frame.
