UNITED STATES PATENT OFFICE
JAMES MAGNUSEN, OF CHICAGO, ILLINOIS.

DESIGN FOR A VAULT-LIGHT.

Specification forming part of Design No. 29,044, dated July 12, 1898.
Application filed July 3, 1897. Serial No. 643,461. Term of patent 7 years.
To all whom it may concern:
    Be it known that I, JAMES MAGNUSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced a new and original Design for Vault-Lights, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
    Figure 1 is a side elevation of a vault-light, showing my new design. Fig. 2 is an end elevation of the same.
    The vault-light consists of a body portion or base B, provided with a flat and attenuated downwardly-projecting extension or drop A. The drop A depends from one side of the base B and is inclined at an oblique angle to the same, so as to extend under it.
The lower surface of the drop A is ridged, corrugated, or provided with prisms.
    The essential feature of my design is the flat and attenuated drop A, extending obliquely under the base B from one of its sides and having its lower or under side provided with prisms.
    Having described my invention, what I claim as new, and desire to secure by Letters Patent, is—
    The design for a vault-light, as herein shown and described.
JAMES MAGNUSEN.
