To all whom it may concern:     Be it known that I, FRANK C. SOPER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Design for a Vault-Light, of which the following is a description.     My invention relates to a new and original design for vault-lights, and is illustrated in the accompanying drawings, wherein—     Figure 1 is a side elevation of a vault-light embodying my design. Fig. 2 is a front view of the vault-light shown in Fig. 1. Fig. 3 is a plan view of the vault-light shown in Fig. 1.     Like letters refer to like parts throughout the several figures.     Referring to the drawings, the vault-light consists of a body portion A, provided with

downwardly-projecting prisms B, said prisms provided on their end surfaces with the diagonal projections or prisms C. The shape, size, and inclination of the large prisms and the projections or prisms C indicate my invention, the essential feature of which is a vault-light provided with a body portion having downwardly-projecting prisms, provided on their end surfaces with diagonal projections or prisms.     I claim--     A design for a vault-light, substantially as herein shown and described.
