Machine for Mixing Mortar.
Description:
Patent for a new and improved machine for mixing mortar. This design "consists in a cylinder composed of bars set into open heads and rotating beneath a hopper . . . so that the material to be mixed rests upon the cylinder, and is rasped or grated off by the motion of the cylinder and received on the inside of the cylinder between the bars. . . . When the material is received inside the cylinder it is carried around by the rotary motion, and is turned over and forced out" (lines 7-22).
