Abstract:
1. A power transmission safety system comprising: a pair of power transmission members, each of said power transmission members having a switch arm; a pair of switch arm engaging members, each reversibly engaging a switch arm of a respective power transmission member; a pair of pivoting shaft members, each coupled to a respective one of said pair of switch arm engaging members on one end, and a rotatable handle on an opposing end; an interlocking power activation bar having a pair of openings positionally located on said interlocking power activation bar at a displacement substantially equal to a distance between said switch arms of said power transmission members, whereby rotation of one of said pivoting shaft members engages a switch arm of a respective power transmission member into an “on” position and displaces said interlocking power activation bar transversely to lock the other of said shafts from rotating, thereby preventing both of said power transmission members from being “on” concurrently.
