SPECIFICATION forming part of Design No. 27,970, dated December 7, 1897. Application filed November 1, 1897. Serial No. 657,104. 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 Designs 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 invention. Fig. 2 is a cross-section therethrough.     A is the body of the prism-light; B, one side thereof; C, a series of prisms thereon; D D, a series of broken or chipped prisms.     As illustrated in the drawings, the fractured or broken prisms present a series of

somewhat regularly-distributed, but irregularly-bordered, recessed, or hollowed-out surfaces. The work is called "fracto-work," and the appearance may be described as that of a series of rain-drops stretched along in regular rows.     The essential features of my design are found in a prism-light comprising a substantially flat thin body with a series of mutilated prisms on one side thereof.     I claim--     The design for a prism-light, substantially as shown and described. HENRY F. BELCHER. Witnesses:     HOMER. L. KRAFT,     BERTHA C. SIMS.
