Abstract
Abstract A method of molding stone-faced pillars comprising attaching stone pieces onto a wooden base, covering the surface of said base, not covered by the stone pieces, with Plaster-of-Paris, spraying numerous coatings of latex rubber on the entire base and stone pieces of the pillar and spraying numerous coatings of liquid base fiberglass on said coatings, peeling off said coatings, and laying them in right angular relationship in a right angular mold and finally pouring wet cement onto the stone-faced portions to reproduce the stone faced pillar model.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
85 words
A method of forming a right angular mold for forming a pair of surfaces of a stone-faced rectangular pillar, comprising forming a rectangular base, attaching stone pieces to two sides of said base, providing separating strips at the corners of said base, applying molding material to said base and stone pieces, also to said strips so as to form two molding strips, each having molding flanges at the edges thereof, removing said strips, attaching two of said flanges together to form a right angular mold.
Claim 2
Independent Claim
85 words
A method of forming a right angular mold for forming a pair of surfaces of a stone-faced rectangular pillar, comprising forming a rectangular base, attaching stone pieces to two sides of said base, providing separating strips at the corners of said base, applying molding material to said base and stone pieces, also to said strips so as to form two molding strips, each having molding flanges at the edges thereof, removing said strips, attaching two of said flanges together to form a right angular mold.
Claim 3
Dependent Claim
16 words
The method recited in claim 1 further comprising providing a base for said right angular mold.
Claim 4
Dependent Claim
72 words
The method recited in claim 1 wherein said base is of wood and wherein said molding material is made up by covering the part of said base which is not covered by stones with Plaster of Paris and applying separate coatings of latex rubber on said part of said base and said stones, then applying several subsequent coats of fiberglass on said latex rubber and stones to form a fiberglass reinforced mold.
Claim 5
Dependent Claim
79 words
The method recited in claim 1 wherein a second right angular mold is made from the remaining two surfaces of said stone-faced rectangular pillar by the method recited in claim 1, and finally, the resulting two right angular molds are connected together so as to form a rectangular mold, thereafter a tubular member is inserted in said rectangular mold, and wet concrete is poured between said tubular member and rectangular mold to mimimize the amount of wet concrete needed.
Claim 6
Dependent Claim
68 words
The method recited in claim 1 wherein three additional right angular molds formed by the method recited in claim 1 are arranged in spaced relationship to form four corners of a composite rectangular pillar mold by inserting marble strips therein so as to extend between said right angular molds, and inserting tubular means in said pillar mold and pouring wet cement between said tubular means and pillar mold.
