Abstract
Abstract A method of making simulated stained glass articles, and articles, such as Tiffany lamp shades made thereby, comprising forming a first pre-form of translucent material with first and second smooth surfaces, applying a pre-patterned colored film over the first surface of the first pre-form, forming a second pre-form of translucent material with a smooth first surface and preformed in the second surface channels adapted to register with the boundaries of the different colors of the film, placing the second pre-form over the first pre-form so that the first surface of the second pre-form is in contact with the film, applying a leading effect in the channels and sealing the free edges of the two pre-forms to one another.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
A simulated stained glass article comprising as a united structure, in combination: a. a first rigid preform of translucent material of a shape and size of the finished article having a smooth first surface; b. a prepatterned colored film on the first surface of the first preform and in register therewith; c. a second rigid preform of translucent material of a shape and size of said finished article having a smooth first surface located in contact with the film and a second surface with channels formed therein in register with the boundaries of said colored prepattern of the film, the second surface being remote from said film and said channels extending only part-way through the thickness of said second preform; d. a material in said channels which has a lead-like appearance; and e. means sealing the free edges of the two preforms to one another.
Claim 2
Dependent Claim
145 words
A simulated stained glass article comprising as a united structure, in combination: a. a first rigid preform of translucent material of a shape and size of the finished article having a smooth first surface; b. a prepatterned colored film on the first surface of the first preform and in register therewith; c. a second rigid preform of translucent material of a shape and size of said finished article having a smooth first surface located in contact with the film and a second surface with channels formed therein in register with the boundaries of said colored prepattern of the film, the second surface being remote from said film and said channels extending only part-way through the thickness of said second preform; d. a material in said channels which has a lead-like appearance; and e. means sealing the free edges of the two preforms to one another.
Claim 3
Dependent Claim
42 words
A simulated stained glass article as claimed in claim 1, wherein the first preform is bowl shaped with its inner and outer surfaces smooth and wherein the second preform is of corresponding bowl-shape with its inner surface smooth and outer surface uneven.
Claim 4
Dependent Claim
27 words
A simulated stained glass article as claimed in claim 1, wherein said second preform comprises two preformed sections interlocked with one another to produce said second preform.
