ABSTRACT:
An automobile engine jacket heater includes a body member having a metal sheathed heating element projecting from the reverse face thereof. An expandable yoke assembly is provided on the reverse face of the body member for securing the heater in an aperture of the engine jacket. The yoke assembly includes a plurality of outwardly divergent wing members and a clamp member movable toward and away from the reverse face of the body member by a single screw operable from the obverse face of the body member for spreading the wing members into engagement with the interior surfaces of the engine jacket after the heater is inserted into the jacket aperture. The screw is loosely journaled in an aperture in the body member of larger diameter than that of the screw threads whereby the screw can be canted to an angle of at least 10 to 15 degrees relative to the face of the body member. The wing members are separately formed and have an enlarged aperture at their inner end through which the screw passes. The enlarged aperture permits the wing members to independently pivot in the axial plane of the screw. Cheeks on the wing member retain the wing members and clamp member in unitary assembled relationship.
