Production of decorative tiles and wall and floor surfaces

Claim 1

THE METHOD OF FORMING A CEMENTITIOUS TILE WHICH COMPRISES THE STEPS OF: ADJUSTING THE RELATIVE POSITION OF A DIE HAVING AN UPPER FLAT SURFACE AND A FRAME MEMBER HAVING A FLAT UPPER SURFACE, SAID FRAME MEMBER HAVING AN APERTURE FORMED THEREIN WHICH COOPERATES WITH SAID DIE TO DEFINE A MOLDING CHAMBER, SAID ADJUSTING STEP DEFINING A CHAMBER HAVING A FIRST DEPTH; FILLING SAID CHAMBER WITH A CHARGE OF A FIRST CEMENTITIOUS POWDERED MATERIAL LEVEL WITH SAID UPPER SURFACE OF SAID FRAME MEMBER; YIELDINGLY PRESSING THE UPPER SURFACE OF SAID CHARGE TO RENDER THE DENSITY OF SAID CHARGE SUBSTANTIALLY UNIFORM THROUGHTOUT THE CHARGE, THE THICKNESS OF SAID CHARGE VARYING IN ACCORDANCE WITH ITS INITAL DENSITY DISTRIBUTION; READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO REDUCE THE DEPTH OF SAID CHAMBER TO A SECOND DEPTH NOT EXCEEDING THE MINIMUM THICKNESS OF SAID CHARGE AFTER SAID YIELDINGLY PRESSING STEP; SCRAPING THE UPPER SURFACE OF SAID CHARGE TO PRODUCE A LAYER OF SAID FIRST MATERIAL WHICH IS OF UNIFORM THICKNESS; READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO INCREASE THE DEPTH OF SAID CHAMBER TO A THIRD DEPTH GREATER THAN SAID FIRST DEPTH; FILLING THE SPACE IN SAID CHAMBER ABOVE SAID FIRST MATERIAL WITH A CHARGE OF A SECOND POWDERED CEMENTITIOUS MATERIAL LEVEL WITH THE UPPER SURFACE OF FRAME MEMBER; YIELDINGLY PRESSING THE SURFACE OF SAID CHARGE OF SECOND MATERIAL TO RENDER THE DENSITY OF SAID CHARGE SUBSTANTIALLY UNIFORM THROUGHOUT THE CHARGE, THE THICKNESS OF SAID SECOND CHARGE VARYING IN ACCORDANCE WITH ITS INITIAL DENSITY DISTRIBUTION; AGAIN READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO REDUCE THE DEPTH OF SAID CHAMBER TO A FOURTH DEPTH NOT EXCEEDING THE COMBINED MINIMUM THICKNESSES OF SAID FIRST AND SECOND MATERIALS AFTER THE SECOND OF SAID YIELDINGLY PRESSING STEPS; SCRAPING THE UPPER SURFACE OF SAID CHARGE OF SAID SECOND MATERIAL TO PRODUCE A UNIFORM COMBINED THICKNESS FOR SAID FIRST AND SECOND MATERIALS; AND APPLYING PRESSURE TO THE UPPER SURFACE OF SAID CHARGE OF SECOND MATERIAL TO COMPRESS BOTH OF SAID MATEIRALS SIMULTANEOUSLY, SAID LAST NAMED PRESSURE APPLYING STEP UTILIZING A RIGID FLAT SURFACE COOPERATING WITH SAID FLAT UPPER SURFACE OF SAID DIE.

Claim 2

THE METHOD OF FORMING A CEMENTITIOUS TILE WHICH COMPRISES THE STEPS OF: ADJUSTING THE RELATIVE POSITION OF A DIE HAVING AN UPPER FLAT SURFACE AND A FRAME MEMBER HAVING A FLAT UPPER SURFACE, SAID FRAME MEMBER HAVING AN APERTURE FORMED THEREIN WHICH COOPERATES WITH SAID DIE TO DEFINE A MOLDING CHAMBER, SAID ADJUSTING STEP DEFINING A CHAMBER HAVING A FIRST DEPTH; FILLING SAID CHAMBER WITH A CHARGE OF A FIRST CEMENTITIOUS POWDERED MATERIAL LEVEL WITH SAID UPPER SURFACE OF SAID FRAME MEMBER; YIELDINGLY PRESSING THE UPPER SURFACE OF SAID CHARGE TO RENDER THE DENSITY OF SAID CHARGE SUBSTANTIALLY UNIFORM THROUGHTOUT THE CHARGE, THE THICKNESS OF SAID CHARGE VARYING IN ACCORDANCE WITH ITS INITAL DENSITY DISTRIBUTION; READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO REDUCE THE DEPTH OF SAID CHAMBER TO A SECOND DEPTH NOT EXCEEDING THE MINIMUM THICKNESS OF SAID CHARGE AFTER SAID YIELDINGLY PRESSING STEP; SCRAPING THE UPPER SURFACE OF SAID CHARGE TO PRODUCE A LAYER OF SAID FIRST MATERIAL WHICH IS OF UNIFORM THICKNESS; READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO INCREASE THE DEPTH OF SAID CHAMBER TO A THIRD DEPTH GREATER THAN SAID FIRST DEPTH; FILLING THE SPACE IN SAID CHAMBER ABOVE SAID FIRST MATERIAL WITH A CHARGE OF A SECOND POWDERED CEMENTITIOUS MATERIAL LEVEL WITH THE UPPER SURFACE OF FRAME MEMBER; YIELDINGLY PRESSING THE SURFACE OF SAID CHARGE OF SECOND MATERIAL TO RENDER THE DENSITY OF SAID CHARGE SUBSTANTIALLY UNIFORM THROUGHOUT THE CHARGE, THE THICKNESS OF SAID SECOND CHARGE VARYING IN ACCORDANCE WITH ITS INITIAL DENSITY DISTRIBUTION; AGAIN READJUSTING THE RELATIVE POSITIONS OF SAID DIE AND SAID FRAME MEMBER TO REDUCE THE DEPTH OF SAID CHAMBER TO A FOURTH DEPTH NOT EXCEEDING THE COMBINED MINIMUM THICKNESSES OF SAID FIRST AND SECOND MATERIALS AFTER THE SECOND OF SAID YIELDINGLY PRESSING STEPS; SCRAPING THE UPPER SURFACE OF SAID CHARGE OF SAID SECOND MATERIAL TO PRODUCE A UNIFORM COMBINED THICKNESS FOR SAID FIRST AND SECOND MATERIALS; AND APPLYING PRESSURE TO THE UPPER SURFACE OF SAID CHARGE OF SECOND MATERIAL TO COMPRESS BOTH OF SAID MATEIRALS SIMULTANEOUSLY, SAID LAST NAMED PRESSURE APPLYING STEP UTILIZING A RIGID FLAT SURFACE COOPERATING WITH SAID FLAT UPPER SURFACE OF SAID DIE.
