Abstract

A masonry tool is provided for a concrete block wall which consists of a mechanism for positioning a side end of a first concrete block, with mortar applied thereto, next to a side end of a second concrete block on the wall when being built, so as to form front and rear mortar joints therebetween. A structure on the positioning mechanism is for preventing the mortar from entering into a vertical open space in a third concrete block located below the front and rear mortar joints.

Dependent claims

A masonry tool for a concrete block wall which comprises:

a) means for positioning a side end of a first concrete block, with mortar applied thereto, next to a side end of a second concrete block on the wall when being built, so as to form front and rear mortar joints therebetween, a generally inverted U-shaped frame member, which is sized to fit about the side end of the second concrete block, so that the side end of the first concrete block can fit into said frame member, said generally inverted U-shaped frame member includes a first stanchion to cover a portion of a rear face of the second concrete block at the side end thereof, a portion of a rear face of the first concrete block at the side end thereof and the rear mortar joint therebetween, a second stanchion to cover a portion of a front face of the second concrete block at the side end thereof, a portion of a front face of the first concrete block at the side end thereof and the front mortar joint therebetween, means for retaining said first stanchion and said second stanchion in a vertical parallel spaced apart relationship, said retaining means includes a top end of said first stanchion and a top end of said second stanchion, said retaining means is a crossbar attached to said top end of said first stanchion and said top end of said second stanchion, in which said crossbar will extend across a top surface of the second concrete block, said crossbar includes an extension segment from the top end of said second stanchion, so that a person can grip said extension segment with one hand to manipulate said generally inverted U-shaped frame member;
and
b) means on said positioning means for preventing the mortar from entering into a vertical open space in a third concrete block located below the front and rear mortar joints, said mortar preventing means includes said second stanchion having a horizontal slot located at a bottom end thereof, a blade which fits through said horizontal slot under a bottom surface at the side end of the second concrete block to butt against a bottom end of said first stanchion, so that when the side end of the first concrete block is placed next to the side end of the second concrete block, a bottom surface at the side end of the first concrete block will fit over said blade.
