Abstract
A machine for cleaning mortar from used bricks and the like comprising a hopper for moving bricks onto a feeding position at one end of a channel, a ram for pushing one brick after another, each brick pushing a series of preceding bricks, from the feeding position along the channel and through gangs of interleaved spur gear assemblies which crumble the brick mortar and then through scrapers which remove the crumbled mortar from the bricks. The spur gear assemblies are biased to accommodate different sizes of bricks and the hopper moves the bricks into feeding position one at a time.
