Abstract

Abstract This application discloses a process for forming a layer of masonry-like material on the outside of walls or panels. The process is carried out by using a die which is the same size as the area to be coated. The die is made up of a rigid outside frame with partitions extending between the sides and the ends of the frame. The partitions are rectangular in cross section and are laid out in a pattern which defines the outline of a masonry block of a constructed wall of brick or stone. The material of the partitions have the same thickness as the material to be placed on the wall and the frame of the die is provided with clamps in one embodiment of the invention. The clamps are suitable for clamping it to the panel. In another embodiment of the invention, the die may be supported on suitable supports and lowered into the material after it is placed on the panel or wall.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 170 words
A die to be used in forming a pattern resembling blocks in a layer of hardenable material on a building panel, said die comprising a frame in the form of a grid of relatively rigid material, said frame being of a thickness of the desired depth of demarcations defining said pattern, said frame further comprising laterally and longitudinally extending partitions defining grid openings through said die and being of width approximately equal to mortar joints in masonry walls, said openings being of the size and shape of said blocks, said partitions having the thickness of the depth of the desired pattern, releasable means attached to side edges of said die to removably attach said die to said building panel, said die being adapted to be supported on a building panel with said openings in said die being filled with a plastic hardenable material, said die being adapted to be withdrawn from said material before said material hardens whereby said pattern is left in said material when said die is removed.
Claim 2
Dependent Claim 170 words
A die to be used in forming a pattern resembling blocks in a layer of hardenable material on a building panel, said die comprising a frame in the form of a grid of relatively rigid material, said frame being of a thickness of the desired depth of demarcations defining said pattern, said frame further comprising laterally and longitudinally extending partitions defining grid openings through said die and being of width approximately equal to mortar joints in masonry walls, said openings being of the size and shape of said blocks, said partitions having the thickness of the depth of the desired pattern, releasable means attached to side edges of said die to removably attach said die to said building panel, said die being adapted to be supported on a building panel with said openings in said die being filled with a plastic hardenable material, said die being adapted to be withdrawn from said material before said material hardens whereby said pattern is left in said material when said die is removed.
Claim 3
Dependent Claim 26 words
The die recited in claim 1 wherein said die is made of relatively rigid material having substantially the properties of resiliency and rigidity of structural steel.
