Abstract
Abstract Linear means, particularly for producing a mirror having a discrete transparent portion of a desired shape, configuration or ornamentation and having a backing which may have a discrete image of corresponding shape, configuration or ornamentation affixed in juxtaposition thereto, is set forth. The means of production of said mirror include providing, upon a glass surface, a layer of reflective substance, applying over said reflective substance, a layer of protective resist material which delineates, outlines and profiles said desired shape, configuration or ornamentation, then treating said coated glass surface to set said resist and washing the same to remove unprotected reflective portions delineated by said protective layer and exposed to said wash.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A method of making a mirror with a reflective layer having at least one transparent design portion and having a backing with corresponding discrete design portions juxtaposed thereto comprising: transposing a discrete design from a backing article to a silkscreen; transposing said design from said silkscreen to a unit of glass, having a reflective backing and being correspondingly sized to said desired backing, by superimposing said silkscreen upon said reflective backing and applying a protective resist substance through said silkscreen to areas of said reflective layer not underlying said discrete design portion of said silkscreen; removing, by means of a washing agent, portions of said reflective layer not protected by said resist substance; and applying said backing over said protective resist layer, said transparent design portion of said unit of said mirror and said discrete design portions of said backing being juxtaposed, wherein, subsequent to the application of said protective resist layer, said coated glass is heated to set said protective resist substance, is then slightly cooled in a controlled manner prior to application of said washing agent.
Claim 2
Independent Claim
178 words
A method of making a mirror with a reflective layer having at least one transparent design portion and having a backing with corresponding discrete design portions juxtaposed thereto comprising: transposing a discrete design from a backing article to a silkscreen; transposing said design from said silkscreen to a unit of glass, having a reflective backing and being correspondingly sized to said desired backing, by superimposing said silkscreen upon said reflective backing and applying a protective resist substance through said silkscreen to areas of said reflective layer not underlying said discrete design portion of said silkscreen; removing, by means of a washing agent, portions of said reflective layer not protected by said resist substance; and applying said backing over said protective resist layer, said transparent design portion of said unit of said mirror and said discrete design portions of said backing being juxtaposed, wherein, subsequent to the application of said protective resist layer, said coated glass is heated to set said protective resist substance, is then slightly cooled in a controlled manner prior to application of said washing agent.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein said resist substance is an epoxy and wherein said coated glass is heated to at least about 250° F. and then cooled to about 215° to 220° F.
Claim 4
Dependent Claim
39 words
The method of claim 1 wherein said reflective layer washing agent is caused to puddle upon said coated surface by movable, vertically tensioned pinch rollers, and wherein said protective resist substance is resistant to action of said washing agent.
