DESIGN FOR A PATTERN FOR VAULT-LIGHT FRAMES.
SPECIFICATION forming part of Design No. 22,981, dated December 26, 1893.
Application filed May 6, 1893. Serial No. 473,301. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, JACOB JACOBS, a citizen of the United States, residing at New York city, in the county of New York, and in the State of New York, have invented a certain new and useful Design for a pattern for Vault-Light Frames; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which--
    Figure 1 shows a plan view of a portion of a frame for a vault-light or illuminating tile made in accordance with my design, and Fig. 2, a view of a section on line x, x, of Fig. 1.
    Letters of like name and kind refer to like parts in each of the figures.
    The object of my invention has been to provide a new and useful design for a pattern for the frames of vault-lights or illuminating tiles, and to this end my invention consists in the design, substantially as shown in the drawings and hereinafter specified.
    In the drawings A designates the lower part or base of the frame upon which the lenses B, B, are supported, and C designates the upwardly extending part of the frame, on such base, intended to extend around and inclose the spaces occupied by the lenses, which are ordinarily embedded in cement or other holding material between them and the inner sides of the inclosing parts of frame portion C. The frame so constructed is, in accordance with my present design, arranged so that the light admitting and lens receiving openings in it are in the form of circles and
octagons with sides made concave. These openings are arranged in quincunx order, with the circular ones D, D, surrounding the octagonal ones D', so that their convex sides will be opposite four alternate correspondingly curved convex sides of the octagonal openings.
    Between the parts of the frame inclosing the circular openings, are portions D², rounded as seen in plan view, which have their convex sides opposite the other concave sides of the hexagonal openings, which are not turned directly toward the circular openings.
    It will be understood that the described quincunx arrangement of circular and octagonal openings, and the circular solid portions of the frame intervening between the circular openings, can be continued or repeated throughout a frame of any desired size.
    A frame made in accordance with my design has been found to give a vault-light or illuminating tile a very neat and attractive appearance.
    Having thus described my invention, what I claim is--
    The design for a pattern for a frame for vault lights or illuminating tiles, substantially as shown and described.
    In testimony that I claim the foregoing I have hereunto set my hand this 30th day of March, 1893.
JACOB JACOBS.
