To all, w/wm u; may concern.-
Be it known that I, LUCIAN F. PLYMPTON, a citizen of the United States, residing at North Bend, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Roofing-Tiles, of which the following is a specification.
My invention relates to such roofing-tiles as are shaped byforcing the moist element of which they are composed through a die and cutting off at the desired lengths, necessitating afterward the repressing of each tile, so that when burned and placed upon the roof they may fit at the laps.
It is by the above-described process that heretofore tile has been made to [it at the partswhere one tile has to be placed upon an- I other upon the roofviz., by repressing one an isometric projection oi upper tile; Fig. '5
end of each tile after it has once been forced through the die-thereby making one end of the tile smaller than the die left it, orcausing it to taper in width, in order that it may lit into the other end of the tile as leftby the die. My invention corrects this defect, i having devised a novel-shaped lower tile having a rounded top, with parallel sides thinner than the top and thickened at the bottom and edges and rounded at the edges, thesidosinelining outward.
A distinguishing feature of this tile is the thickened and rounded edges, which renders it possible to shape them by forcingthe moist element of which they are composed through a die, for should they be left thin atthc edges theinc'reased friction-surface in proportion to the surface pressure causes the edges to be torn'and haggled by the process of forcing the element through the die. I attain these objects by the mechanism illustrated in the accompanying drawings,in which Figure 1 is a plan View of a portion of the roof; Fig. 2, a section on line 2 J of Fig. 1; Fig. 8, a section line 3 3 of Fig. 1; Fig. 4, an end View of the lower tile for laying with mortar; Fig. 5, an end view of iopof tile; Fig. (i, an isometricprojection of lower tile; Fig. 7,

Similar letters refer to similar parts throu ghout the several views,
The line b c and the line I It are parallel and show the normal proportionate thickness of the bottom of my lower tile formed to be laid without mortar, the sides projcclingand thinner than the bottom, the top projecting horizontally, and the edges the same thickness as the bottom, but rounded. It will be observed'that the upper surface and the under surface of this tile extend in the same direction, that the periphery of the upper surface and the under surface is the same, and that this tile presents the same crosssection at any part in its length, and that it is susceptible of being constructed by being once forced through a die, but it being necessary in certain instances to provide for mortarspace, (see the die A, Fig. 9, where two rectangular plates having slots G and bolts ii are slid perpendicularly toward each other and made secure by screwing the nuts I, so as to partially obstruct the passage of the clay through the die, thus shapingthe tile shown A, Fig-i-it being the, lower tile to be laid with mortar and differing only from tlie'formcr in this, that the bottom is thinned to form space-i. e., a tile having a Ilat central web with parallel sides andthickened edges and provided with inclined sides thickened and rounded at their edges) and each of the above-described tile formed by one die.
My upper tile 0, formed to cover the upward extending and projecting sides and edges ol two under lilo to shed water into their troughs, is formed by once forcing the moist element of which they are composed through the die C, which imparts to it the shape of the die-orifice, producing a novelshaped upper tile with rounded top thicker than the downward projecting sides and thickened at the edges equal to the thickness at the top, the edges projecting horizontally.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. An under tile for roofing having a ilat bottom, and parallel sides inclined outward and upward, and thinner than the bottom, but thickened and rounded atlhcir edges, prcsentingthe same cross section at any part in its length and the under surface and upper l the joints of a substantially inverted U shape surface of which extend in the same direcin cross section, said covering tile having :1 tion, substantially as described, and for the rounded top, with parallel sides thinner than uses and purposes set forth. the top and thickened at the bottom and 2. An under tile for roofing, having a flat edges, and rounded at, the edges substantially central web, with parallel sides and thickened as shown and for the uses and purposes deedges, and provided with inclined sides thiclcscribed. ened and rounded at their edges, substantially LUCIAN F. PLYMPTON. as described and for the uses and purposes set. forth.
