To all whom it may concern: Be it known that I, EDWARD C. WALLER, 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 Prism-Plates and Borders, of which the following is a description. My invention relates to designs for prism-plates and borders and is illustrated in the accompanying drawings, wherein-- Figure 1 is a view of a prism-plate and border of my design. Fig. 2 is a cross-section therethrough on line 2 2. A is a prism-plate comprising a substantially-flat body with prisms C on one side thereof. |
Surrounding the prism-plate is a border B, dished toward the
prism side, as shown in the cross-section. I have shown the border as
ornamented with open-work at D. The essential feature of my design is found in a prism-plate with a surrounding border dished toward the prism side. I claim-- A design for a prism-plate and border, substantially as shown and described.
