SPECIFICATION forming part of Design No. 27,761, dated October 19, 1897.
Application filed September 8, 1897. Serial No. 650,991. Term of patent 14 years.
To all whom it may concern:
    Be it known that I, JOHN W. MARK, of New York, in the county of New York, and in the State of New York, have invented a certain new and original Design for a Light or Tile; 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 is a perspective view of a light or tile embodying my design, and Fig. 2 a plan view thereof.
    Letters of like name and kind refer to like parts in each of the figures.
    The object of my invention is to provide a new shape or configuration for lights or tiles; and to this end said invention consists in the design for a light or tile, substantially as herein set forth.
    The essential feature of my design consists of a light or tile A, that is quadrangular or four-sided, with a depression B in the central portion of each side.
    The depression B slopes or inclines from
one face of the tile, disappearing when the opposite face is reached, and the surface b at each end thereof is an inclined one.
    Each corner of the light or tile A is chamfered or beveled off, the surface thereof being inclined from one face of the light or tile to the other, as in the case of the depressions B and B. Thus while one face of the light or tile shows the shape of a quadrangle with a depression in each of its four sides and its corners beveled the other face presents such a shape with unbroken sides.
    Having thus described my invention, what I claim is—
    The design for a light or tile, substantially as herein set forth.
    In testimony that I claim the foregoing I have hereunto set my hand this 1st day of September, 1897.
JOHN W. MARK.
