Derbyshire do hereby declare the nature of this invention to be as follows:-
For combination roof covering consisting of tiles and soakers-Tiles of any suitable
size or shape made.of clay, or other suitable substance having a flange, at top, on top
surface and a corresponding flange at the bottom, on the under surface also grooved
on under surface to receive flanges of soakers.
The edges of tiles to be square or rebated to make a more secure joint, which joints
are to be further protected with flanged soakers fitting up into grooves and at top, and
bottom of tiles The soakers to be made of zinc, lead, iron, paper, felt clay or other
suitable substance.
The tiles to be grooved. on top surface for using without soakers when required.
The ridge to have wide flange for bedding on tiles and which flange will be
perforated for ventilation.

Improvements in and connected with Roof Coverings.
I, CHARLES SHEWBROOKS of 10 Elder. Yard Chesterfield, in the County of Derby,
Architect and Surveyor 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 :-
This invention relates in the first place to the construction of the tiles used for the
general covering of the roof, the object being to reduce the weight upon the roof
timbers, and to render the covering watertight without the use of moriar; in the
second place to ventilating ridge tiles, the object being to obtain ample ventilation,
with protection from rain or snow.
The annexed sheets of drawings clearly illustrate my invention, similar letters of
reference indicate similar parts in any of the figures.
Figs. 1, 2. 3. 4, are a plan and various sections of the roof covering. Fig. 5, the
bottom edge view.
Fig. 6. underside of tile and channel tile.
Figs. 7 & 8. sectional views of same.
Fig. 9. plan of roofing on reduced scale.
Figs. 10, 11, 12, 13, various views of ridge tile.
A, is the principal tile, B the channel tile. or soaker. The tiles.A, and channel
tiles B, may be inade of any suitable material and of any required size. The tiles A
have a flange C, along the top edge, rising from the top or upper face, and also have
a similar flange D upon the under face along the bottom edge, which overlaps the
flange C, of the next lower tile.
The under face of the tile A is provided with long vertical grooves E to receive
corresponding ribs formed upon the face of the channel tile B, (or soaker).
The abutting edges of the tiles may be plain, or they may be rebated, or made to
overlap, or be otherwise constructed to protect the joint, but they are protected chiefly
by a channel tile B, (or soaker) provided with longitudinal ribs F, which fit into the
grooves E in the under surface of tile A as before described: The channel tiles may
be made attached to the tiles A if preferred.

page_text: The flange C, is set down in the centre, so as to form a gap G, clearly seen in
Figs. 1 and 8 the bottom of the gap being a rib H which fits into a groove I in the
channel tile B, and at each end of the said groove a notch J, is made to engage with
the ends of the flange C.
I also prefer, to increase the security of the tiles by forming notches K in the
channel tiles and corresponding lugs L upon the underside of tiles A to fit into them,
in addition to the notches J.
The said channel tiles have a flange M at the top projecting both above and below,
the part below supports the channel tiles by being hooked over the laths N, Fig. 4.
It will thus be seen that the various parts are well supported and held together and
that any wet penetrating through the vertical joints will be caught upon the channel
tiles B, and be carried down between the ribs F, and drop off upon the surface of the
next lower tile A.
My improved ventilator tiles for the ridges of buildings, either in combination with
or without the system of roofing above described are made as follows, reference being
made to the Figures, 10, 11, 12, 13. The tile is constructed in two parts P & Q, the
part P forming a cover for the part Q, and they may be connected or fastened
together by cement, or by wood pegs, or the like appliances.
Between the two parts is a chamber or air-passage, having an opening on each
side R, R', communicating with the atmosphere, and a central opening S, communi-
cating with the interior of the roof, which is protected from the entrance of wet by
ridges T.
Fig. 10, is a cross section of such a ridge tile.
Fig. 11, shows how the ends overlap.
Fig. 12, is a plan of the top of part Q, with upper part P removed. Fig. 13,
side elevation of the complete ridge tile, showing side opening R, and portions of
the adjacent ridge tiles. The two wide surfaces are for bedding upon the roofing
tiles with mortar or cement.
,
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1-In the formation of roof coverings, the Tiles proper A, constructed with a
flange Chaving a gap G in its central part, to receive the end of a channel tile or
soaker B, and also with vertical grooves E, to receive corresponding ribs F, upon
the said channel tiles; in combination with a channel tile B, having two ribs F,
bottom groove I, notches J, and double flange M, all arranged, and fitting together,
substantially as hereinbefore described and illustrated.
2-A Ventilating ridge-tile, constructed in two parts P & Q (to be afterwards
secured together) having an opening R & R on either side, and a central opening S,
ridges T, and bedding faces V, substantially as described and illustrated in Figs. 10.
