SPECIFICATION forming part of Design No. 27,972, dated December 7, 1897. Application filed November 1, 1897. Serial No. 657,106. Term of patent 14 years.

To all whom it may concern:     Be it known that I, HENRY F. BELCHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a certain new and original Design for Prism-Lights, of which the following is a specification.     My invention relates to designs for prism-lights.     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; B, one side thereof; C C, a series of fractured prisms on the other side thereof, and D D indicate the somewhat irregularly bordered, recessed, or hollowed-out surfaces formed upon such fractured prisms.

The work is called "fracto-work."     The essential features of my design are found in a prism-light comprising a substantially flat thin body with a series of prisms wholly mutilated or fractured, so as to present regularly-distributed rows or irregularly bordered, recessed, or hollowed-out surfaces, as shown.     I claim--     A design for a prism-light, substantially as shown and described. HENRY F. BELCHER. Witnesses:     HOMER. L. KRAFT,     BERTHA C. SIMS.
