ABSTRACT:
A multi-purpose scraping apparatus is disclosed which enables the interchangeability of scraping blades. The apparatus is made of a handle, a shank and a blade receiving assembly, the shank being interposed between the handle and the blade receiving assembly. The blade receiving assembly comprises a back plate, a spring plate, a spring tongue and means for securing the spring plate to the back plate. The spring tongue extends from the spring plate and provides means for moving the blade receiving assembly from a gripping position to a releasing position. The back plate and the spring plate are thus constructed and arranged to cooperatively engage a blade to be used with the apparatus and to bias the blade receiving assembly in the gripping position. Thus, the spring tongue is moveable to effect movement of the blade receiving assembly from the gripping position to the releasing position.
