SPECIFICATION forming part of Letters Patent No. 467,832, dated January 26, 1892.

Application filed March 28, 1891.

T0 aZZ whom it may concern:

Be it known that 1, CHARLES T. RICHARDS, of St. Louis, Missouri, have made a new and useful Improvement in Illuminating- Tiles, of which the following is a full, clear, and exact description.

The improvement relates to the construction of the bulls-eye and the means for securing it in the frame-work, substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which Figure l is a plan exhibiting a portion of a tile having the improvement embodied therein; Fig. 2, a vertical section on the line 2 2 of Fig. 1, the bulls-eye being shown in side elevation; Fig. 3, a vertical section on the line 3 3 of Fig. 1, the bulls-eye being shown in side elevation; Fig. 4, a bottom view of a bullseye and its washer, the parts being relatively arranged as when the washer is encircling the neck of the bulls-eye, but the bulls-eye as yet has not been turned around to become interlocked with the washer; Fig. 5, a bottom view showing abulls-eye interlocked with its washer; Fig. 6, a view of a washer; and Fig. '7 a view employed to illustrate various forms of the bulls-eye, one form being shown in side elevation, and other forms are indicated by the broken lines.

The same letters of reference denote the same parts.

The present improvement is adaptable to various constructions, to pavements, vaults, coal-chutes, tanks, roof-plates, wrought and cast metal doors, floors of buildings, holds of ships and decks, prison-cell windows, and other analogous structures.

A represents any plate, tile, or frame adapted for having, containing, or supporting the improvedbulls-eyes. Said plate, tile, orframe, so long as it is adapted for receiving the bullseyes, as hereinafter described, may vary in form, according to the nature of the particular construction or place in which it is being used.

B represents one of the improved bullseyes. It is constructed and attached so that when in position it is drawn downward into its openingdin the plate to cause its peripheryb to be pressed against the wall of said opening a or against any interposed layer of Serial No. 386,858- (No model.)

cement with more force than is due to its weight simply, and thereby fixed more socurely in position than is the ordinary bullseye in its support. This is accomplished, preferably, as follows: The bulls-eye 011 its inner or under side is extended to form a shoulder 11, which is connected with the main portion Z1 of the bulls-eye by means of a neck U At least two of these shoulders I) b are preferably used, and when there are two such shoulders they are usually arranged to be opposite each other, substantially as shown.

C represents a perforated plate in the nature, say, of a washer, substantially as shown. Its perforation o is adapted to receive said shouldered end of the bulls-eyethat is, the central portion of the perforation is of proper size and shape to receive the neck b of the bulls-eye, and at c c the perforation is extended to enable the shoulders I) b of the bulls-eye to be passed through the perforation. The parts are assembled and fastened in position by dropping the bulls-eye into the opening in the plate and passing its shouldered end through the opening in the washer, and thence turning the bulls-eye around to cause its shoulders 12 b to come beneath the portions 0 0 respectively, of the Washer, and then and by means of, say, the screws D D, which engage in and are adapted to be Worked through the washer and whose points press upward against the under side of the plate A and preferably in indentations a a in said plate, causing said washer to press downward upon said shoulders b b of the bulls-eye. The first-named position of the bulls-eye with relation to the washer islshown in Fig. 4, and in Fig. 5 the bulls-eye is shown turned around in position for the washer to press downward upon it, as described. Any other suitable means may be employed to press said washer downward, and said washer and said bulls-eye may be variously relatively constructed to enable said washer when it is thus pressed downward to bear upon the bulls-eye and draw it downward into its opening in the plate A. The bulls-eyes may be of any suitable diameter and be otherwise proportioned and formed, as may be desired, so long as they embody the principle of the present improvement. They may be flat on top or crowned, and they may in depth be plate A, the other enlargement against the suited to a wrought-iron plate or support A, such as is shown in Figs. 2 and3,ior they may be made deeper, as indicated by the outlines b 12 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 12 in the main part of the bullseye is a preferable means for more securely uniting the bulls-cye with any layer of cement which i may be used in setting the bulls-eyes in their support. i

I claim- 1. In an illuminating-tile, the combination of the lens having enlarged ends, one of which fits Within or against the supporting bulls-eye having the neck and shouldered portion, th'eperforate'd washer, and the screws D, passing through said washer, substantially as described.

Witness my hand this 25th day of March, 1891.

CHARLES T. RICHARDS.
