Abstract

Apparatus for manufacturing a brick having a roughened side surface including interconnected, upright, side plates defining a mold cavity having generally the shape of a brick to be formed. A bottom plate is shiftable vertically from a position against the lower edges of the side plates to form a bottom for the mold and a position spaced a distance therebelow. A power-operated pusher mounted above the side plates is shiftable downwardly into the region between the side plates for forcing a brick formed in the mold outwardly through the bottom of the mold when the bottom plate is lowered. One of the side plates has a lip projecting substantially normally outwardly therefrom into the path along which a side of a brick will be moved as it is forced from the mold. This lip scrapes a side of the brick to produce a roughened surface thereon.
