iLLUlVilNATlixiG=TlLE SPECIFICATION forming part of Letters Patent No. 339 421-, dated April 6, 1886.

Application tilezl November 13, l8r3. Serial No. 111.688. (No modal.)

T0 (b/ Z whom it nmz concern:

Be it known that I, Jaoon .Lioons, of Xew York city, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Illuminating i ilcsz and I do herebydeclare that the following is a full. clear, and exact description thereof, reference being bad to the accompany ing drawings, making a part of this specification, in which- Figure 1 is a perspective view from the lower side of one of the plain lensesemployed by me. Fig.2 is a plan view from above oi a portion of the metal tile in which the same is set, and Fig. 3 is a vertical section of said tile fully glazed and combined with another similar tile.

Letters of like name and kind refer to like parts in each of the figures.

My invention is intended to obviate certain defects which sometimes existin illuminatingtilcs, and to lessen the liability to injury caused by shipment of the same; and it consists, principally, in an illuminating-tile provided with elongated light openings, in combination with lenses which are correspondingly elongated, and within their peripheries are -each provided with a circumferentiali 5 joints formed by the plastic material possess groove that corresponds to and is adapted to embrace the flange which forms the bottom of the lensrecess, substantially as and for the purpose hereinafter specified.

It consists, further, in an illuminating-tile provided upon or within its edge with arib or a groove which may be caused to fit within or over the corresponding groove or rib of a contiguous tile, in combination with cement placed between such engaging edges, and with bolts which pass through the lower portions of each tile and through the supporting-frame, substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents my improved tile, which consists of a metal plate having its upper face recessed, and provided within such recess with a series of light-openings, a, that have any desired relative arrangement and are each surrounded by a curb, a, that extends, preferably, about one-half the distance between the bottom of said recess and the upper surface of said tile.

Each light-openinga is somewhat elongated,

and within the same is fitted a glass lens, B, that is correspondingly shaped and has such sire as to enable its lower end to be easily passed into the same. Near its lower end each of said lenses is provided with a circumferential groove, 3), which'has such vertical dimensions as to enable it to contain the flange of that forms the edge of said light-opening, and has such depth as to permit said lens, alter insertion within said opening, to be turned until its longest diameter is in a line with the shortest diameter of the latter, in which position said lens is securely locked by the engagement of said groove with said flange.

Before placing the lens B in position, its groove 1) is filled with plastic cement, which, by the turning of said lens within its opening, is caused to closely fill the space between the flange c and groove 1), the surplus material being pressed outward and removed. After all of said lenses are in position the spaces between their peripheries are filled with said plastic cement C, and the upper surface of the same, while soft, covered with powdered flint, in order to afford a firm foot-hold.

Lenses thus secured within a tile are not liable to be loosened while the latter is being transported to or placed in position, while the far greater durability and are more certain to be water-tight than are those produced by any of the usual methods.

In order that tight joints may be secured between the edges of contiguous tiles, I provide each tile A at such point with a rib, a, or groove to, which extends horizontally along its edge, and when said tile is in place, passes into or over the corresponding groove a or rib a of the adjacent tile. Plastic cement O is placed between the edges of said tiles before or aft-er the same are combined, so as to closely fill the space and produce a tight joint at such point.

The tiles A are each firmly secured to the supporting-frame l) by means of bolts E,whieh pass through said parts, as shown in Fig. 3. Enid bolts are preferably placed in position within said tile before the spaces around the lenses are filled with cement C, but may, if desired, be inserted at any time by leaving suitable openings and afterward filling the same with cement,so as to cover the bolt-head.

I OO

The joint thus produced possesses great strength and durability, and is not liable to leak under any ordinary usage.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- 1. The lens for illuminating-tiles, having its lower portion elongated diametrically and provided with a circumferential groove, substantially as and for the purpose specified.

2. In combination with the lens-supporting portion of an illuminating-tile provided with an elongated lensopening, the lens having its lower portion correspondingly shaped and adapted to be passed through the lens-opening, and having a circumferential groove adapted to allow the lens to be turned after its lower portion has been passed through the opening, all substantially as and for the purpose shown.

3. In combination with alens-support of an illuminating-tile provided with one or more elongated openings. one or morelenses having their lower portions shaped to correspond with such openings and provided with circumferential grooves adapted to allow the lenses to be turned in the openings to bring their longest diameters at right angles to the longest diameters of the openings, and a body of cement surrounding the lenses, substantially as and for the purpose described.

4. In combination with the lenssupporting portion of the tile provided with elongated openings, the lenses correspondingly shaped and grooved to receive the edges of the openings, turned to bring their longest diameters at right angles to the longest diameters of the openings, and cement in the grooves in the lenses, substantially as and for the purpose specified.

5. In combination with the lens-support of an illuminating-tile provided with an elongated lensopening, the lens correspondingly shaped and having the cylindrical neck adapted to allow the lens to be rotated in the opening to bring the longer diameter of the lens across the opening, substantially as and for the purpose described.

6. In combination with asupporting-frame, an illuminatingtile having in its edge a groove and an illuminating-tile having in its edge a rib entering the groove in the other tile, cement placed between the engaging edges of the tiles, and bolts passing through the lower portions of the tiles and portions of the supporting-frame, substantially as and for the purpose described. 7

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of November, A. D. 1883.
