发明名称 Mortar trough
摘要 A tool or building construction implement is disclosed for use in constructing brick work, particularly for use by a bricklayer in construction of brick walls, or other brickwork, of conventional bricks and mortar. With use of the present invention, need is eliminated for the usual mortar board and trowel. The mortar trough is semi-cylindrical in shape, containing when filled with mortar the exact amount of mortar required to prepare brick joints cleanly and with savings of mortar otherwise wasted when excessive amounts are applied. The mortar trough requires no handle, and can be used for work in crowded places, such as under an overhang, near walls, and the like. In a first method of use, rotation substantially about a longitudinal axis allows deposition of the mortar contents on the row of bricks to be built up with an additional layer. In a second method of use, the trough can be filled and tilted to permit the mortar contents to flow along the surface to be worked. The trough is closed at one end and left open at the opposite end.
