  • Patent number: 10066402
    Abstract: The masonry trowel (20) comprises a plate (22) extending in a plane (?) including an open surface (26) and a holding surface (24) having a pair of front perimeters (30) converging toward one another from a pair of shoulders (28) to define a V shape (30-30) and a point (32) in the plate (22). A handle (38) extends along a gripping axis (A) connected to the open surface (26) by a shank (44). A pair of walls (46) extend from and along the V shape (30-30) to an upper rim (48) to present an outlet (50) defined by each of the walls (46) having a front edge (52) slanting upward from the holding surface (24) and along each of the walls (46) at an egress angle (?) to a junction (54) with the upper rim (48). Each of the walls (46) is tilted at an included angle (?) to space the junctions (54) and the front edges (52) at a constant width (w) along the outlet (50). In an engaged position, the trowel is at a slope angle (?) to engage the front edges (52) with the vertical joint between bricks.
