MASONRY TROWEL

摘要

The masonry trowel (20) comprises a plate (22) extending in a plane (ρ) 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 (α) to a junction (54) with the upper rim (48). Each of the walls (46) is tilted at an included angle (θ) 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 (φ) to engage the front edges (52) with the vertical joint between bricks.

主权项

1. A masonry trowel (20) for applying mortar in a vertical joint between at least two bricks adjacent one another in a row with the vertical joint disposed centrally above a lower brick, said masonry trowel (20) comprising;
a plate (22) extending in a plane (ρ) and having a holding surface (24) and an open surface (26) being parallel and spaced from one another at a thin thickness (t) defining a pair of shoulders (28) at a maximum span and a pair of front perimeters (30) converging toward one another in a forward direction from said shoulders (28) of said plate (22) to define a V shape (30-30) with a point (32) in said plate (22), a handle (38) of cylindrical shape extending along a gripping axis (A) between a distal end (40) and a support end (42) connected to said open surface (26) of said plate (22) with said gripping axis (A) disposed at an acute grip angle (β) relative to said plane (ρ), a pair of walls (46) extending transversely from said holding surface (24) of said plate (22) and along said V shape (30-30) of said front perimeters (30) of said plate (22) to an upper rim (48) and defining an outlet (50), and characterized by, said outlet (50) defined by each of said walls (46) having a front edge (52) slanting transversely from said holding surface (24) of said plate (22) and along each of said walls (46) at an egress angle (α) less than ninety degrees (90°) relative to said plane (ρ) to a respective junction (54) with said upper rim (48) whereby the mortar may be channeled along said holding surface (24) and through said outlet (50) and into the vertical joint between the bricks as said point (32) rests upon the lower brick in an engaged position with said holding surface (24) on a downward slant at a slope angle (φ) equaling ninety degrees (90°) minus said egress angle (α) relative to horizontal to engage said front edges (52) with the vertical joint between the bricks.
