Bakin g Bricks by Electricity.

A western inventor has 'designed an ingenious method for 'baking bricks by electricity, Which isdescr ibed in’The Industrial World as follows: “The machine is a simple contrivance, consisting of a table covered with iron brick tiiolds, to which the electric current is applied. The table is 14 by 8 feet and holds 1,000 molds, which are joined together like a lot of ‘‘pigeon holes.” Each mold is the size of a brick which has been pressed but not baked, and each has a loose cover so fitted as to follow the brick as it shrinks. The bricks are taken from the presses and placed in the molds, the covers adjusted and the Current turned on. The iron sides of the mold form the “resistance,” and thus the bricks are virtually inclosed by walls of fire. “When the bricks have shrunk to the light size, the sinking' covers of the molds break connection and thus automatically turn off the current when the baking is done, and the bricks are dumped. It is olaimed that only three hours and a half are required to bake bricks by this process, and that they are harder and better than those produced by the present process.”
