ABSTRACT:
A plaster or mortar mixer embodying a stub shaft mounting assembly for the mixer paddles disposed interiorly of the mixing drum and a reduction gear drive system enabling use of a standard electric motor or universal internal combustion engine with the reduction drive system employing a belt and pulleys, a sprocket chain and sprocket gears and a meshing gear assembly which eliminates the necessity of a relatively expensive reduction gear unit thereby rendering the mixer less expensive to manufacture and maintain. The stub shaft mounting of the mixer paddles enables the paddles to be permanently and rigidly secured to the paddle shaft in the form of a supporting tube such as by welding or the like with the stub shafts detachably connected to the tube in order to facilitate the removal of and replacement of the paddles and tube.
