US 4,970,797 A · Mason's scale and masonry guide employing said scale

Abstract

A masons scale for use in laying courses of brick, adapted to allow a mason to calculate appropriate mortar thicknesses between rows of bricks when constructing a brick wall, so as to evenly space the rows of bricks in such wall. Such scale consists of a plurality of groups of mutually adjacent, individually colored bands arranged along a substantially elongate, flat surface, each group spaced a progressively decreasing distance apart from the next group progressing from bottom to top of the scale, the midpoint of each colored band spaced a uniform distance from the midpoint of a correspondingly colored band in an adjacent group of colored bands. A masonry guide incorporating such scale is also provided, further comprising an elongate post member, and bracket means affixed at each end of the post member, to allow the masonry guide and the associated scale to be affixed to the side of a structure in a vertically upright position.
