Abstract
Abstract A composite marble laminate structure and method of making same having a base layer of a wood product with a surface layer of marble pieces bonded thereto, the marble pieces being bonded to the wood layer by a two part curable bonding material prior to surface finishing of the marble layer and thereafter subjecting the structure to a grinding and polishing process including a water bath.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
69 words
A STONE FACED LAMINATE STRUCTURE COMPRISING A THIN LAYER OF DISCRETE PIECES OF STONE BONDED BY A CURABLE BONDING MATERIAL TO A SURFACE OF A WOOD FIBER UNDERLAYMENT, THE LAYER OF STONE HAVING A TOP SURFACE THEREON REMOTE FROM THE UNDERLAYMENT, THE TOP SURFACE BEING SMOOTH AND PLANAR AND FINISHED IN SITU AFTER BONDING TO THE UNDERLAYMENT AND SAID STONE HAVING A ROUGH BOTTOM SURFACE BONDED TO THE UNDERLAYMENT.
Claim 2
Dependent Claim
69 words
A STONE FACED LAMINATE STRUCTURE COMPRISING A THIN LAYER OF DISCRETE PIECES OF STONE BONDED BY A CURABLE BONDING MATERIAL TO A SURFACE OF A WOOD FIBER UNDERLAYMENT, THE LAYER OF STONE HAVING A TOP SURFACE THEREON REMOTE FROM THE UNDERLAYMENT, THE TOP SURFACE BEING SMOOTH AND PLANAR AND FINISHED IN SITU AFTER BONDING TO THE UNDERLAYMENT AND SAID STONE HAVING A ROUGH BOTTOM SURFACE BONDED TO THE UNDERLAYMENT.
Claim 3
Dependent Claim
26 words
The structure of claim 1 wherein the bond forms a bond layer intermediate the marble and the underlayment, the bond layer comprising a two-part epoxy cement.
Claim 4
Dependent Claim
28 words
The structure of claim 2 wherein the underlayment has top, botton and side surfaces and at least some of said surfaces are coated with a water impervious coating.
Claim 5
Independent Claim
174 words
The method of constructing a composite structure of stone on wood which comprises the steps of: providing an underlayment of a board of wood fiber of less than 1 inch thickness, providing a substantially planar top surface on the underlayment, providing a plurality of discrete pieces of stone having a thickness of less than 1/2 inch and top and bottom rough cut surfaces generally parallel to one another, applying to bottom surfaces of the stone pieces to the top planar surface of the underlayment with a curable bonding material, curing the bonding material to bond the stone pieces to the underlayment, subjecting the resultant composite structure to a water bath, subjecting the top surfaces of the stone pieces to a rough grinding with the composite subjected to the water bath, then subjecting the top surfaces of the stone pieces to a finish polishing operation with the composite subjected to a water bath to produce a smooth top surface on the composite, then removing the composite from the water bath and drying the composite structure.
Claim 6
Independent Claim
174 words
The method of constructing a composite structure of stone on wood which comprises the steps of: providing an underlayment of a board of wood fiber of less than 1 inch thickness, providing a substantially planar top surface on the underlayment, providing a plurality of discrete pieces of stone having a thickness of less than 1/2 inch and top and bottom rough cut surfaces generally parallel to one another, applying to bottom surfaces of the stone pieces to the top planar surface of the underlayment with a curable bonding material, curing the bonding material to bond the stone pieces to the underlayment, subjecting the resultant composite structure to a water bath, subjecting the top surfaces of the stone pieces to a rough grinding with the composite subjected to the water bath, then subjecting the top surfaces of the stone pieces to a finish polishing operation with the composite subjected to a water bath to produce a smooth top surface on the composite, then removing the composite from the water bath and drying the composite structure.
Claim 7
Dependent Claim
31 words
The method of claim 4 including the additional step of applying a sealing coating to all surfaces of the underlayment other than the planar top surface before applying the stone pieces.
Claim 8
Dependent Claim
107 words
A stone faced composite structure comprising an underlayment, said underlayment comprising a wood fiber structure of a density of at least 60 pounds per cubic foot and a thickness of less than 1 inch, a toP layer of stone, the stone having a thickness of less than 1/2 inch, the top layer including a plurality of discrete pieces, an intermediate layer of bonding material bonding bottom surfaces of the pieces to a top surface of the underlayment, the bonding material being a two-part epoxy cement, the bottom surface of the pieces being rough, the top surface of the top layer being smooth polished in situ and planar.
Claim 9
Dependent Claim
107 words
A stone faced composite structure comprising an underlayment, said underlayment comprising a wood fiber structure of a density of at least 60 pounds per cubic foot and a thickness of less than 1 inch, a toP layer of stone, the stone having a thickness of less than 1/2 inch, the top layer including a plurality of discrete pieces, an intermediate layer of bonding material bonding bottom surfaces of the pieces to a top surface of the underlayment, the bonding material being a two-part epoxy cement, the bottom surface of the pieces being rough, the top surface of the top layer being smooth polished in situ and planar.
Claim 10
Dependent Claim
20 words
The structure of claim 6 wherein side and bottom surfaces of the underlayment are coated with a water impervious sealant.
Claim 11
Dependent Claim
19 words
The structure of claim 6 wherein peripheral portions of the top layer extend beyond peripheral portions of the underlayment.
Claim 12
Dependent Claim
21 words
The method of claim 4 including the further step of cutting the composite structure to size after curing the bonding material.
Claim 13
Dependent Claim
10 words
The structure of claim 1, wherein the stone is marble.
Claim 14
Dependent Claim
10 words
The structure of claim 1, wherein the stone is onyx.
Claim 15
Dependent Claim
23 words
The structure of claim 10, wherein the marble is less then 1/2 inch thick and the underlayment is less than 1 inch thick.
