Abstract
Abstract This invention is directed to a method for making intricate inlay designs in wood and other materials. The novel method of this invention uses a laser to selectively form patterns in two pieces of material by vaporizing unwanted portions thereof. One piece of material has the negative pattern of the other piece of material. Unlike previous methods of making inlays, these patterns do not penetrate completely the thickness of the pieces. A suitable adhesive is then applied to the pieces of material. The two pieces of material are then mated together so that the vaporized area of one piece mates with the raised (non-vaporized) area of the other piece. When the adhesive has set, one surface is sanded or planed until the thickness of the joined pieces is reduced to include the area where the two pieces have been mated. This area will be an intricate inlay which will be composed of both pieces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A method of making inlays using laser engraving comprising the steps of: laser engraving a positive image of the inlay on a first layer of material; laser engraving a negative image of the inlay on a second layer of material; applying adhesive to at least one of said first and second layers of material; mating said first and second layers of material such that said positive image and said negative image are engaged at a common surface and are adhered by said adhesive to form a composite; and removing a portion of at least one of said first and second layers of material to expose said inlay.
Claim 2
Independent Claim
107 words
A method of making inlays using laser engraving comprising the steps of: laser engraving a positive image of the inlay on a first layer of material; laser engraving a negative image of the inlay on a second layer of material; applying adhesive to at least one of said first and second layers of material; mating said first and second layers of material such that said positive image and said negative image are engaged at a common surface and are adhered by said adhesive to form a composite; and removing a portion of at least one of said first and second layers of material to expose said inlay.
Claim 3
Dependent Claim
84 words
The method recited in claim 1 wherein: said first and second layers of material include composite structures having a plurality of laminations, each of said composite structures having at least a lamination of metal and a lamination of wood, said laser engraving steps comprise the removal of selected portions of the wood lamination of each composite structure whereby each image of the inlay is formed of wood, and said removing step comprises the removal of one of said metal laminations to expose said inlay.
Claim 4
Dependent Claim
39 words
The method recited in claim 2 including the steps of: adhering the exposed wood inlay to a further layer of wood; and removing the remaining lamination of metal to produce a wood inlay on said further layer of wood.
Claim 5
Independent Claim
131 words
A method of making inlays using laser engraving comprising the steps of: forming a first composite structure of a lamination of metal and a lamination of wood; forming a second composite structure of a lamination of metal and a lamination of wood; laser engraving a positive image of the inlay on said first composite structure and a negative image of the inlay on said second composite structure, said laser engraving removing selected portions of each wood lamination to form said positive image and said negative image; applying adhesive to at least one of the composite structures; mating said structures such that said positive image and said negative image are engaged at a common surface and are adhered by said adhesive; and removing one of said metal laminations to expose said inlay.
Claim 6
Independent Claim
131 words
A method of making inlays using laser engraving comprising the steps of: forming a first composite structure of a lamination of metal and a lamination of wood; forming a second composite structure of a lamination of metal and a lamination of wood; laser engraving a positive image of the inlay on said first composite structure and a negative image of the inlay on said second composite structure, said laser engraving removing selected portions of each wood lamination to form said positive image and said negative image; applying adhesive to at least one of the composite structures; mating said structures such that said positive image and said negative image are engaged at a common surface and are adhered by said adhesive; and removing one of said metal laminations to expose said inlay.
Claim 7
Dependent Claim
38 words
The method recited in claim 4 including the steps of: adhering the exposed inlay to a further layer of wood; and removing the remaining lamination of metal to provide a wood inlay on said further layer of wood.
