PROVISIONAL SPECIFICATION.
Improvements in Roofing Tiles.
We, CHARLES MANCHIP of Bridgewater, Somersetshire, Clerk in the employ-
ment of The Somerset Trading Co. Ltd., and ROBERT YARDE FOLEY of
Bridgewater, Somersetshire, Manager of The Somerset Trading Co. Ltd., do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to devise a locking device which shall hold the
tiles firmly in position, and prevent them from being stripped off the roof by wind
or by other causes.
The invention is applicable to all kinds of tiles, but we will describe it in reference
to a tile having a raised central rib formed by hollowing out the underside of the
tile. The rib and groove are preferably of taper form, and the groove is provided
preferably towards its wider and lower end with an undercut projection while the
narrower end of the groove is formed with an undercut recess or tongue. When
the tiles are being placed in position the undercut recess or tongue engages with
the undercut projection on the tile next below it and so on, which locks the tiles
firmly in position.
The tiles at their underside may be provided with tongues or projections to
engage with the slating battens of the roof.

Improvements in Roofing Tiles.
We, CHARLES MANCHIP of Bridgewater, Somersetshire, Clerk in the employ-
ment of The Somerset Trading Co. Ltd., and ROBERT YARDE FOLEY of
Bridgewater, Somersetshire, Manager of The Somerset Trading Co. Ltd., 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 this invention is to devise a locking device which shall hold the
tiles firmly in position, and prevent them from being stripped off the roof by wind
or by other causes.
The invention is applicable to all kinds of tiles, but we will describe it in reference
to a tile having a raised central rib formed by hollowing out the underside of the
tile. The rib and groove are preferably of taper form, and the groove is provided
preferably towards its wider and lower end with an undercut projection while the
narrower end of the groove is formed with an undercut recess or tongue. When
the tiles are being placed in position the undercut recess or tongue engages with
the undercut projection on the tile next below it and so on, which locks the tiles
firmly in position.
The tiles at their underside may be provided with tongues or projections to engage
with the slating battens of the roof.
In the accompanying drawings
Figure 1 is a perspective view of four tiles fitted together according to our
invention,
Figure 2 is a perspective view of one of the tiles inverted and
Figure 3 is a longitudinal central section through two tiles constructed

page_text: according to our invention showing the manner of attaching them to the slating
battens.
Like letters represent like parts in the drawings.
A is a tile and A' the raised central rib thereof. Each tile in the accom-
panying drawings is shown with two raised ribs of substantially semi-circular form
the central one A' and another A2 at one edge which is adapted to overlap the
small, preferably rectangular rib A³ of the tile laid next to it in the same horizontal
row. At its underside the tile is formed with grooves A' A' corresponding
respectively with the ribs A' A* formed at the upper side. These ribs and grooves
are preferably of taper form the grooves at their larger and lower ends being of
such size as to fit nicely over the smaller and upper ends of the ribs of the tiles
next below them as shown in Figure 1.
B are the undercut projections provided near the lower end of the tiles and C are
the undercut recesses formed at their upper ends.
D are the tongues or projections provided at the underside of the tiles for
engaging with the slating-battens or tile laths E as shown in Figure 3 to prevent
the tiles from slipping down and F are holes for receiving the nails G (shown in
dotted lines in Figure 3) by which the tiles may be secured down to the laths E.
The left-hand lower corner and the right-hand upper corner of each tile are cut
off at an angle as shown in Figures 1 and 2 so that the tiles may fit well together;
the joint made by any two of these cut off corners is covered by one of the hollow
ribs A2 so as to protect it from rain and the like.
H is a recess formed in the underside of each tile for accommodating the upper
part of the rib A³ of the tile next below it.
When the tiles are being placed in position the undercut projection B of each
tile engages with the undercut recess C of the tile next below it (excepting of
course those of the lowest row of tiles) which prevents them from being stripped
off the roof by wind or other causes, additional security in this respect also being
obtained by nailing the tiles to the laths E as before described.
The before described tile may be modified without departing from the spirit of
the invention for example instead of forming the abutting surfaces of the pro-
jection B and recess C at an incline to the face of the tile as shown in the accom-
panying drawings they may be formed at right angles thereto and a portion of the
projection B parallel with the tile be arranged to pass under the upper edge of the
tile next below it, but the arrangement shown in the drawings is preferred.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination with a roofing tile of an undercut projection such as B and
undercut recess such as C substantially as described and illustrated in the accom-
panying drawings.
2. The complete roofing tile substantially as described and illustrated in the
accompanying drawings.
