Improvements in Roofing Tiles.
Year: 1897

page_text: I, FREDERICK LATHAM, of Sledmere, near Driffield, in the County of York,
Clerk of Works, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct roofing tiles so as to be weather-proof
without sheeting, bedding, or pointing, and which have a pleasing and picturesque
appearance and can be easily and economically fixed and replaced.
I construct my tiles with a weather or water bar or flange on the outside of the
top end of the tile, and a weather bar or flange on the underside of the bottom
end of the tile.
The tile is also tapered or cut away at the outside of its bottom end. One side
edge of the tile is rounded or beaded, forming a groove, and the other edge is
made with a rounded hooked part or scroll to fit over the beaded edge of the next
tile. The bead is cut away at an angle at top and bottom to allow for overlapping,
the scroll being similarly cut away at the top, and one tile fits over the other,
covering up the nail holes in the weather bar of same, and forming a complete
chain or band of weather proof tiles from caves to ridge, the whole being no
more costly than the ordinary construction. Projections or feet are formed on
the underside of the top of each tile to engage with the lath.

Improvements in Roofing Tiles.
I, FREDERICK LATHAM, of Sledmere, near Driffield, in the County of York,
Clerk of Works, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: -
The object of my invention is to construct roofing tiles which when fixed are
weatherproof without sheeting, bedding, or pointing, and which have a pleasing
and picturesque appearance and can be easily and economically fixed and replaced.

page_text: Fig. 3 is a transverse section of tiles in position.
I construct my roofing tile with a water-bar or weather-flange A on the outside
of the head of the tile, and a similar water-bar or weather-flange B on the under-
side of the tail of the tile. The said water-bar or weather-flange B overlaps the
tile immediately below it, and bears against the water-bar or weather-flange A,
through which pass the nails C for securing the tile to the lath 1). The said
nails C are consequently protected from the rain, and are not liable to corrode,
nor can water obtain ingress through the nail holes.
One side edge of the tile is rounded, forming an upwardly projecting bead or
hooked rib E. The opposite side edge has a scroll or hooked roll F which fits
over the beaded edge of the next tile. The bead or rib E is cut away at an angle
at the head and the tail of the tile to allow the courses to overlap, the scroll F
being similarly cut away at the head. The outside of the tail of the tile is
preferably bevelled or tapered, so as to allow water to quickly drain off the roof.
A projection or projections G, engaging with the lath D, may be provided on
the bed of each tile to further secure the tiles in position and prevent slipping.
When in position, the tiles form an interlocking chain from eaves to ridge.
and are therefore not liable to slip or be dislodged by gusts of wind. They are
also weatherproof and self-ventilating.
The water-bars or weather-flanges A and B may be applied to any other form
of roofing tile.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:- -
1. In a roofing tile, the employment of a water-bar or weather-flange at the
head and tail of the tile, substantially as shown and described.
2. In a roofing tile, the combination of the water-bars or weather flanges A
and B, the projecting bead or hooked rib E, the scroll or hooked roll F, and the
projection G, substantially as, and for the purposes, shown and described.
