摘要： A rake for cleaning brick joints consisting of a tubular crossbar attached to a handle nonperpendicularly thereto so that the ends of the crossbar are offset relative to each other. Rollers are journaled to the ends of the crossbar at a spacing equal to twice the distance between brick joints, the rollers being parallel to the handle. A depending raking member is adjustably clamped to the midportion of the crossbar so as to engage in a brick joint while the rollers ride in the two outwardly adjacent parallel brick joints.
