To all whom it may concern: Be it known that I, THADDEUS HYATT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Illuminating-Tile Constructions, of which the following is a specification, reference being had to the accompanying drawings. My present invention relates more especially to that class of illuminating-tile constructions known as "concrete lights," in which the walking or weather surface of the tile between the glasses consists of hardened hydraulic cement overlaid while in a plastic state on the underlying grating. My improvement applies to this class of, illuminating-tiling, whether made in what is known as the "one-casting panel tile system, wherein each panel-space is filled with a grating cast in one piece, or whether made in what is known as the "fractional" system, such as is shown and claimed in my former application, No. 159,202, filed 17th March, 1885, patented April 7, 1885, No. 315,412, wherein the panel is filled with fractional gratings, junctioned directly together to form the complete tile, and made without dead-work borders on their junction sides. Heretofore in concrete tiling, particularly in the one-casting tile system, the grating or tile has been made like a dish, or with a rising rim around its border to hold and confine the plastic cement, which rimmed grating or tile has been then fitted within the surrounding rim of the panel-space of the foundation-frame, and filled with cement flush with the tops of the glasses, and the construction seam or crevice between the rimmed grating or tile and the rim of the panel-frame is also, filled with cement to make a water-tight joint, such gratings or tiles being held to the foundation-frame by bolting or other mechanical means. In my former fractional system referred to, I showed the fractional gratings as faced with hardened hydraulic cement before they were placed in the panel-frame to form the tile. Now in my present improvement I omit the raised marginal rim on the tile, (whether in the one-casting panel or fractional-panel system,) and these tiles are first fitted naked into the rimmed |
panel-frame, the glasses being placed in the light-holes either before or
after the gratings are laid in place, and the whole is then over-laid with
plastic hydraulic cement flush with the rim of the panel. Hence by this
means the cement is carried in a homogeneous manner over the joints between
the tile and the panel-rim and over the joints between the fractions of the
grating, if made in fractions, and these joints are thus not only concealed
and rendered water-tight, but the tile is secured more firmly in the panel,
and the sections thereof bound together, and the glasses are secured in the
grating, and a weather and walking surface of uniform appearance produced
throughout the panel, which results are all effected at the one action in
filling the panel with the plastic cement, thereby presenting most desirable
advantages. My invention therefore consists in the features above outlined, as hereinafter fully set forth. In the drawings annexed, Figure 1 presents a cross-section of a panel filled with a rimmed cemented grating according to the old system. Fig. 2 is a similar section showing my improved unrimmed grating set into the panel previous to the insertion of the glasses and the application of the cement. Fig. 3 is the same as Fig. 2 with the glasses inserted in the light-holes of the grating. Fig. 4 is a similar section showing the work finished by the flooding or spreading of the plastic cement over the naked unrimmed grating between the glasses and flush with the rim of the panel-frame. Fig. 5 is a plan view of two panels filled with fractional gratings which were concreted before being placed in the panel. Fig. 6 is a similar plan view showing my improved construction. Fig. 7 is a longitudinal section of a panel filled with fractional gratings made and concreted according to my present improvement. In the ordinary method of manufacture, as before stated, the grating or tile is made in the form of a dish-- that is to say, the tile or perforated plate is cast with sides or a standing rim around its edges, so as to hold the plastic cement when poured or put upon the face of the tile. This device was made originally in concrete lights, when as yet the article was |
