TILE FOR COPING'.

SPECIFICATION forming part of Letters Patent No. 374,705, dated December 13, 1887.

Application filed January 14, 1887. Serial No. 224,330.

To all whom it may concern..-

Beit known that we, GEORGE B. RoBBINs and HARRY W. BELL, both of the city and Ycounty of New York, in the State of New York, have invented a certain new and useful Improvement in Tiles for Coping, of whichY the following is a specification.

Ourimproved tile overcomes a difficulty experienced with the use of ordinary tiles, as adjacent buildings are constructed .of different heights. When a brick building Vis completed, standing alone, with the wall at each end extending, as usual, a little above the roof, the copingtiles should sit fairly on the tops of their respective walls, projecting over about equally outside and inside. When a higher building is run up alongside,it necessitates the removal of these tiles. Our invention allows them to be set anew on the same wall which they were originally -placed on, a change iu the position only being necessary to make them well adapted for the new conditions. To facilitate the removal without breaking, they should be set originally on the solitary wall with but little cement or mortar. On being 'lifted in preparing for the change only a very small proportion will be broken and require new to be applied. In the main the old tiles may be set on the wall, simply `shifting them inward, so as to allow the'next wall to be carried up smoothly past. The tiles on being shifted overhang entirely on the inner face of the wall. The change of position gives them a greater inclination. This is highly desirable, in order to carry away the increased quantity of rain-water which, with some directions of the wind, will come down from the perpendicular face of the adjacent wall. Our improved tile may be made in a continuous length by a tile-machine having a die'with an aperture of the required form. This mode, which has long been practiced in making tiles for other purposes, being availed of for the production of a continuous length' of our tile, the soft material is afterward cut by a stretched wire or otherwise into short lengths, the cut ends prepared by hand, and the thus-completed biscuit is dried and burned. This form allows the ends of adjacent tiles to match together with a rabbet. This insures that the tiles are held in the correct position.

alone.

may be effected by dexterously cutting along the edge with a suitable knife bent at right angles. It facilitates the manufacture and the burning without warping to make our tiles in pairs, the hollow or under sides being applied together.

The following is a description of whatwe consider the best means of carrying out the invention.

The accompanying drawings form a part of this specification.

Figure 1 is a vertical cross-section showing the tile laid as a coping on a wall standing Fig. 2 shows the same wall with the coping-tile shifted in position to allow another wall to be carried up to a greater height alongside. Fig. 3 is a longitudinal section on the line w in Fig. l. It showsclearly the rabbets by which the adjacent tiles are joined. Figs. 4 and 5 are perspective views showing the adjacent ends of two tiles. Fig. 6 is 0n a larger scale. Itis a cross-section showing two of the tiles in the process of manufacture.

Similar letters of reference indicate'corresponding parts in all the-figuresl where theyoccur.

A is the upper portion of the end wall of a brick building. A is the adjoining wall of an adjacent building, built afterward and carried higher. i

B is the main body of our coping-tile.

Certain portions are designated by additional marks, as B B2, 85o. B is a hanging lip on the lower or inner edge of the tile. B2 is a hanging lip on the higher or outer edge of the tile.

Abearing-surface, b, is formed on the under A while it stands alone. The upper surface of the -tile is slightly inclined. If the higher wall, A,is afterward built alongside, our coping-tiles are, as a preliminary step, lifted from 5 their seats, which can be done after slightly jarring them. After the wall Ahas been carried up past the top of A,onr tiles are applied i anew upon the top of the wall A; but in this case they are set so that the base of the lip B2 xo bears on the outer edge of the wall A adjacent to the higher wall, A.

Cement may be applied in any quantities to make a firm coherence in this second laying of the tiles, as they are expected to remain l5 permanently attached under all future conditions.

Ve have in our experiments made the tiles in pairs, arranged as shown in Fig. 6, and propose to continue to do so. The form of the die should be such that the two tiles formzo ing a pair shall be joinedjust sufficiently to retain their positions in drying and burning, and yet allow the two tiles t0 be separated without destroying either tile.

We claim as our inventionv 25 The coping B, having projections B B, the latter forming an acute angle with the surface of the coping and abutting against a wall, substantially as set forth.

In testimony whereof we have hereunto set 3o our hands, at New York city, this 12th day of January, 1887 in thepresence of two subscribing witnesses.
