DESIGN FOR A PRISM-LIGHT.
SPECIFICATION forming part of Design No. 27,986, dated December '7, 1897.
Application filed October 22, 1897. Serial No. 656,098- Term of patent 14 years- To all whom it may concern.-
Be it known that I, FRANK L. WRIGHT, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented acertain newand original Design for Prism-Lights, of which the following is a specification.
My invention relates to designs for prismplates.
Figure 1 is a plan view of a prism-plate embodying my design. Fig. 2 is a section therethrough.
A is the body of the prism-plate.
B B are a series of surface areas substantially uniform in appearance and produced by the lines of separation O C, which cross the surface of the body of the plate. D D are prisms on the opposite side.
About the outer edge of the prism-plate are a series of ornamental lines E E, produced on the outer surface areas and which have a distinct and characteristic form, so as to produce a sort of ornamental border for the pris mplate.
F F are ornamental lines produced on the inner surface areas, each surface area having a design formed of such lines similar to the design on the other inner areas. Thus there is produced an inner field having a sort of mosaic appearance, with an outer border having a distinct ornamentation.
The essential features of my design are found in a prism-plate comprising a body with prisms on one side and a series of lines of separation on the other which divide it into a series of substantially uniform surface areas, the outer areas ornamented to prod uco the effect of a border and the inner areas ornamented in a uniform manner so as to give the effect of an inner mosaic-like field.
A design for a prism-plate, substantially as shown and described.
