To 025 whom it may concern:
Be it known that I, HENRY F. BELGHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and original Design for 1risn1-Ligl1ts, of which the following is a specification.
My invention relates to designs for prisinlights.
Figure 1 is a plan view of a prism-light embodying my design. Fig. 2 is a cross-section therethrough.
A is the body of the prism-light; I a design thereon flush with the surface; 0, a series of prisms.
When a prisin light of my design is examined, there is a continually changing effect of the design due to the presence of the prisms as a field as the point of view is changed.
\Vith reference particularly to such lines in the design as lie diagonally to the prisms, there is great variation in appearance as the position of the observer is changed.
The essential features of my design are found in a prismlight comprising a substantially flat relatively thin body having a series of prisms on one side and a design on the other side thereof flush with the surface, said design havinglines which lie diagonally across the prisms.
I claim- A design for a prism-light, substantially as shown and described.
