Abstract
A masonry tool for raking unhardened mortar at the predetermined depth between courses of brick at either open wall locations or within tight corners. This tool comprises an elongated handle having an upper side and a lower side, the forward and terminal ends. A rake and carriage assembly is attached to the foward end and provides a pair of wheels oriented for movement along a line substantially parallel with the handle axis. This carriage includes a first raking device which extends beyond a rim of the wheels such that a terminal portion of the raking device may project into a joint separating adjacent bricks as the wheels roll across an exposed face thereof. A second raking device is attached at the terminal end of the handle and projects upward with respect to the upper side to substantially the same predetermined depth as that depth provided with the first raking device. The user is thereby enabled to insert the second raking device into corner locations or other areas of spacial constraint to remove loose mortar not otherwise accessible because of the carriage assembly.
