Abstract
Abstract A method of forming a simulated lead light involves the application of opaque cames to the surface of a transparent or translucent sheet of material, in which the opaque cames are built up successive applications of adhesive and opaque particulate material, such as silicon carbide. The adhesive can be screen printed onto the carrier surface and the particulate material can be dusted onto the printed adhesive. The application of adhesive and particulate material can be repeated until a raised came of desired thickness is built up on the carrier surface to simulate a lead came. The method can also be used in conjunction with the screen printing of colors onto the carrier surface to simulate stained glass separated by simulated lead cames.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
A method of forming a simulated lead light in which opaque cames are applied to a surface of a transparent or translucent carrier material, characterised in that: the cames are built up by applying an adhesive material to the carrier surface in lines or strips corresponding to the position of desired cames, applying on opaque particulate material to said adhesive lines or strips, removing unadhered particulate material, and repeating the steps of applying adhesive material and particulate material to build up raised cames on the carrier surface.
Claim 2
Independent Claim
87 words
A method of forming a simulated lead light in which opaque cames are applied to a surface of a transparent or translucent carrier material, characterised in that: the cames are built up by applying an adhesive material to the carrier surface in lines or strips corresponding to the position of desired cames, applying on opaque particulate material to said adhesive lines or strips, removing unadhered particulate material, and repeating the steps of applying adhesive material and particulate material to build up raised cames on the carrier surface.
Claim 3
Dependent Claim
17 words
A method as claimed in claim 1, characterised in that the particulate material consists of silicon carbide.
Claim 4
Dependent Claim
25 words
A method as claimed in claim 2, characterised in that the adhesive is an epoxy based ink which is screen printed onto the carrier surface.
Claim 5
Dependent Claim
38 words
A method as claimed in claim 3, characterised in that said particulate material is applied initially as a coarse grit in the range of 120-180 grit size, and subsequent layers of particulate material are of finer grit size.
Claim 6
Dependent Claim
25 words
A method as claimed in claim 4, characterised in that the subsequent layers of particulate material are chosen from the range of 320-600 grit size.
Claim 7
Dependent Claim
33 words
A method as claimed in claim 5, characterised in that the cames are applied to both surfaces of a carrier sheet, the cames on each surface being in register one with the other.
Claim 8
Dependent Claim
25 words
A method as claimed in claim 5, characterised in that one or both surfaces of the carrier material is or are coloured by screen printing.
Claim 9
Dependent Claim
13 words
A simulated lead light manufactured in accordance with the method of claim 1.
