Abstract
Abstract A one-piece guide adapted to be inserted into mortar, between recessed surfaces presented by opposing faces of adjacent glass blocks, to space and align them with respect in each other in the formation of a masonry structure. The guide comprises a relatively thin frame including longitudinal and transverse arms having joined to their free ends bodies that are spaced transversely from said each other a distance only slightly less than the width of said recessed face surfaces.

Total Claims: 23
Claim 1
Independent Claim
184 words
A one-piece guide adapted to be inserted into an adhesive compound, such as mortar, between recessed surfaces of predetermined width presented by opposing faces of adjacent units, such as glass blocks, to space and align said units with respect to each other in the formation of a masonry structure, said guide comprising: (a) a generally T-shaped frame including a longitudinal arm and a transverse arm joined at one end to a medial portion of said longitudinal arm; (b) a pair of longitudinally spaced first and second bodies joined to opposite ends of said longitudinal arm; (c) a third body joined to a free end of said transverse arm; (d) said bodies each having a thickness substantially greater than the thickness of said frame and presenting flat upper and lower surfaces that are parallel to each other and that lie in the same planes as corresponding surfaces of the other bodies of said guide; (e) said third body being spaced transversely on said guide from said first and second bodies a distance only slightly less than the width of one of said recessed face surfaces.
