suited to a wrought-iron plate or support A, such as is shown in Figs. 2 and 3, or they may be made deeper, as indicated by the outlines b4 b5, Fig. 7, and which respectively indicate a flat or a crowned top adapted to a cast-metal support, such as shown at A', Fig. 7. The groove b6 in the main part of the bull's-eye is a preferable means for more securely uniting the bull's-eye with any layer of cement which may be used in setting the bull's-eyes in their support.     I claim--     1. In an illuminating-tile, the combination of the lens having enlarged ends, one of which fits within or against the supporting-plate A, the other enlargement against the

washer C, and set-screws D for separating the plate and washer, whereby the lens is compressed upon its bearing against the supporting-plate, substantially as described.     2. The combination of the support A, the bull's-eye having the neck and shouldered portion, the perforated washer, and the screws D, passing through said washer, substantially as described.     Witness my hand this 25th day of March, 1891. CHARLES T. RICHARDS. Witnesses:     C. D. MOODY,     B. F. REX.
