SPECIFICATION forming part of Design No. 18,286, dated May 1, 1888.
Application filed December 22, 1887. Serial No. 258,776. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, PETER H. JACKSON, a citizen of the United States, residing at the city and county of San Francisco, and State of California, have invented and produced a new and original Design for Sidewalk Dead-Light Frames, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
    My invention consists of a novel design for an iron frame.
    My design consists in the peculiar configuration of upwardly-projecting points.
    The leading feature of my design is the triangular-shaped projections or spurs arranged equidistant from each other around each of the openings, so that while a part of the points are common to each of the adjacent openings the set of points around any one of the openings will form the appearance of a star.
    Referring to the accompanying drawings, Figure 1 is a plan and Fig. 2 a sectional view of part of the frame, showing my design.
    A is the frame within which the cylindrical openings are made, and C are the upwardly-projecting points or spurs forming part of the plate and rising between the openings. These points are made triangular in shape, and the sides are curved, so as to have the same center for each of the curved sides as that of the opening which is adjacent to that side. The design thus formed produces the effect of a six-pointed star around each of the openings.
    Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is--
    The design for a frame for sidewalk dead-lights, consisting of triangular or star shaped points formed upon and projecting upwardly from the frame between the openings, substantially as shown and described.
    In witness whereof I have hereunto set my hand.
