ABSTRACT:
An engine block heater adapted for insertion in an opening in the block wall of an automobile engine has a plug member and a novel yoke assembly for securing the heater within the opening. The yoke assembly includes a pair of wing members each having one end thereof abutting the inner face of the heater plug. Each of the wing members is hingedly mounted on and carried by a respective one of the opposite ends of a pressure bar so that each wing member is pivotable about the associated end of the pressure bar and adapted to fulcrum thereon. A screw passes through an axially extending opening in the plug member and is threaded into a tapped opening in the pressure bar. Upon insertion of the heater in the opening in the block wall, the screw is tightened to draw the pressure bar towards the inner face of the heater, thus causing the wing members to pivot about the ends of the pressure bar. This results in those ends of the wing members that contact the inner face of the heater plug being moved slidably towards each other across the inner face while the outer ends of the wing members are moved apart from each other until they overlie and engage with the inner surface of the engine block wall about the inner end of the opening.
