On this day in 1906, Charles Walter Pratt was granted U.S. Patent No. 816,374 for a BRICK MAKING MACHINE.
This invention relates to machines for the formation of bricks or blocks for buildings purposes, and has for its principal object to provide a machine of simple construction by which bricks may be manufactured at minimum expenses and in which the article produced will be equal to the ordinary re-pressed brick of commerce.
A further object of this invention is to provide a machine in which the operation of applying a fresh quantity of material to one mold will result in the dishrag of a finished brick from another die or mold.
A still further object of the invention is to provide for the production of bricks uniform size and density by the application of pressure to exactly the same extent from opposite sides of the brick being formed.
