Abstract
Abstract Brass plaque indicia indicating products are provided according to the present invention which can be economically produced by stamping of brass plate. Prior to the present invention stamping of brass plate to define brass indicia was not economical relative to forging techniques due to the high amount of scrap brass plate which resulted by the stamping operation. The present invention recognizes that the scrap produced during this stamping of the indicia can provide a brass plaque having an interior which defines an outline of the indicia and if a background member is secured behind the brass plate this combination defines the desired indicia. Therefore by stamping of brass indicia and using the remaining scrap to define a further brass plaque which in combination with a background member defines the indicia, the stamping operation becomes very economical relative to a forging operation as two brass products for identifying indicia are produced by the one stamping operation. Furthermore, it has been found by providing a polished brass surface and a background member of contrasting color, the visibility of the indicium is greatly increased with decreasing lighting conditions relative to the recognition of the brass indicium itself. This increased visibility is due to the light reflective nature of the brass plaques and the contrasting color of the background member which advantageously diffuses light to further enhance the contrast.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
155 words
A stamping process for producing brass products identifying indicium for securement to the exterior of buildings said products being made from brass plate having a polished surface which reflects a high portion of incident light comprising: cutting the brass plate to an appropriate size, blanking out the indicium from the brass plate interior to the periphery thereof to produce both a brass indicium and a brass plate indicium outlining portion, securing a background plate of metal or plastic having a light diffusing surface to the rear face of said brass plate indicium outlining portion in a manner to expose said light diffusing surface within said outlining portion, the outline of said indicium being easily recognizable due to the contrast between said light diffusing surface and said brass plate, said method producing a first product defined by the blanked indicium and a second product defined by said brass plate indicium outlining portion and said background plate.
Claim 2
Dependent Claim
155 words
A stamping process for producing brass products identifying indicium for securement to the exterior of buildings said products being made from brass plate having a polished surface which reflects a high portion of incident light comprising: cutting the brass plate to an appropriate size, blanking out the indicium from the brass plate interior to the periphery thereof to produce both a brass indicium and a brass plate indicium outlining portion, securing a background plate of metal or plastic having a light diffusing surface to the rear face of said brass plate indicium outlining portion in a manner to expose said light diffusing surface within said outlining portion, the outline of said indicium being easily recognizable due to the contrast between said light diffusing surface and said brass plate, said method producing a first product defined by the blanked indicium and a second product defined by said brass plate indicium outlining portion and said background plate.
Claim 3
Dependent Claim
36 words
A stamping process as claimed in claim 1 including polishing the brass plate prior to blanking out the indicium and including straightening both said indicium and said plate indicium outlining portion after blanking out the indicium.
Claim 4
Dependent Claim
20 words
A stamping process as claimed in claim 2 including securing said background plate and said outlining portion by gluing thereof.
Claim 5
Dependent Claim
135 words
A process for producing two brass plates for use in identifying an alphabetic or numeric indicium from a single brass plate with minimal scrap material, said brass plate having a light reflective surface said process comprising: stamping the desired indicium from the interior of such brass plate in a manner such that said indicium was generally centered in such plate to produce a brass indicium and a brass plate defining an outline of such indicium within the periphery of said plate, and securing a background plate of metal or plastic having a light diffusing surface relative to the light reflective surface of said brass plate to said outline defining plate and thereby form an indicium of the light diffusing surface exposed within and framed by the light reflective surface of the brass plate outlining member.
Claim 6
Dependent Claim
135 words
A process for producing two brass plates for use in identifying an alphabetic or numeric indicium from a single brass plate with minimal scrap material, said brass plate having a light reflective surface said process comprising: stamping the desired indicium from the interior of such brass plate in a manner such that said indicium was generally centered in such plate to produce a brass indicium and a brass plate defining an outline of such indicium within the periphery of said plate, and securing a background plate of metal or plastic having a light diffusing surface relative to the light reflective surface of said brass plate to said outline defining plate and thereby form an indicium of the light diffusing surface exposed within and framed by the light reflective surface of the brass plate outlining member.
Claim 7
Dependent Claim
32 words
A process as claimed in claim 4 including securing portions of the brass plate interior to the outline of the indicium to said background in such a manner to define the indicium.
Claim 8
Dependent Claim
161 words
A plaque for securement to an exterior wall of a building or other structure and define within the plaque an alphabetic or numeric indicium, comprising a metal plate means having a front face of brass plate or brass alloy plate and a rear face, a portion of said metal plate means being removed to define within the periphery of the plate means a brass outline of said indicium, and a background plate of metal or plastic secured to the rear face of said metal plate means and exposed through said metal plate means within the outline of said indicium, said front face having a light reflective surface and said background plate exposed through said metal plate means having a light diffusing surface, said light reflective surface and said light diffusing surface being of contrasting colours emphasizing the outline of the indicium which is further enhanced due to the dissimilar light reflective characteristics of said metal plate means and said background plate.
