Specification forming part of Design No. 28,016, dated December 7, 1897.
Application filed October 21, 1897. Serial No. 655,971. Term of patent 14 years.
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, of which the following is a description.
    My invention relates to designs for prism-plates and borders.
    Figure 1 is a plan view of a prism-plate and border embodying my design. Fig. 2 is a section therethrough on line 2 2.
    A is the body of the prism-plate; B B the border, and C the prisms.
    The border is dished away from the prisms, and I have shown the border as ornamented with part open-work ornamentation.
    The essential features of my design are found in a prism-plate and border comprising a body with prisms on one side and a surrounding border dished away from the prisms.
    I claim--
    A design for a prism-plate substantially as herein shown and described.
EDWARD C. WALLER.
