Patent ID: 8766118

Claim:
An actuator comprising: a shelf that includes a pivot cone having an opening defined therein, a first member that includes a weight movable between an operational state and a tripped state, a first shaft extending upwardly from the weight and through the opening in the pivot cone, and a first plate affixed to the first shaft, wherein the first plate is supported by the pivot cone, a second member that includes a second plate in contact with the first plate, and a second shaft extending upwardly from the second plate, a trigger lever latch having first and second ends, a first portion operatively associated with the second shaft and a second portion extending upwardly at an angle away from the first portion, and a trigger pin that defines an axis and has an engagement surface defined thereon, wherein the trigger pin is movable between an operational state and a tripped state, wherein the trigger pin is biased toward the tripped state, and wherein the second end of the trigger lever latch is engaged with the engagement surface to hold the trigger pin in the operational state, whereby movement of the weight from the operational state to the tripped state moves the second end of the trigger lever latch downwardly and out of engagement with the engagement surface, and the trigger pin is biased to the tripped state.
