Tile manufacturer do hereby declare the nature of my invention for IMPROVE-
MENTS IN ROOFING TILES to be as follows:-
1 That it is a pressed corrugated cross-bonding groove jointed Roofing Tile.
2 That the groove joint is formed at the highest part of the corrugation as
shewn in drawing at B. C. and E F G the groove at F is to carry off any
water falling on the joint.
3 That the Tile is made so as to cross-bond as shewn in complete section of Tile
in drawing H. I.

page_text: I WILLIAM FINCH of Alfred Street Burnham Somersetshire Roofing Tile Manu-
facturer do hereby declare the nature of my invention for IMPROVEMENTS IN
ROOFING TILES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
My Invention has for its object to provide roofing tiles which when they are
placed together on the roof, form a perfectly watertight covering. According to
my Invention I make the tiles, and fix them so that the joints of the tiles the one
with the other oecur at the apex or highest part of ridges or corrugations formed
by the tiles, and I preferably form in the meeting faces of the joints, grooves which
constitute channels for the escape of any water that may enter the joints. In
eonstructing tiles according to my Invention I make the tiles upon the principle
shewn in transverse section in Figure 1, that is to say, the tiles are so made that
there is at each side of each completed tile an upwardly directed side of a
corrugation or ridge as at a a, so that when the tiles are placed together the joints
of the tiles occur at the apex or highest part of the corrugation or ridge as shewn in
transverse section in Figure 2. In place however of making the abutting edges or
faces of the tiles plain as in Figures 1 and 2, I prefer to make them with grooves
to act as water channels as hereinbefore described.
Figure 3 shows in transverse section one form of groove for a tile thus made,
and Figure 4 shews also in transverse section, another form which I prefer as being
more readily made.
Figures 3 and 4* shew in transverse section the joints formed by the said tiles
constructed as shewn in Figures 3 and 4. The projection 6 forms a lip for directing
the water into the groove c.
In manufacturing the tiles with grooves, the most preferable way will be found
to be to first shape the clay as in Figure 5, which may be effected in a machine of
the kind used in making drain pipes, but of course with the dies properly shaped
to give the shape of tiles required. The tiles thus formed have rounded sides and
after being partially dried, and while still in a plastic state they are placed and
pressed in moulds, shaped so as to give the grooved or channelled formation to the
sides of the tiles, and to form the usual "buttons" or projections and nail holes for
attaching the tiles to the roof-It will be understood that the opposite sides of the
moulds are shaped at the one side to give the groove c, and at the other side to
give the lip b for the drip, so that the tiles are all alike, and the opposed sides or
faces of adjacent tiles at every joint form the requisite groove and lip between
them The tiles may be dried and fired in the ordinary way. I do not limit
myself to any particular shape of the grooves in the abutting faces of the tiles, nor
to the shape of the body part of the tile, provided there is a corrugation or ridge
formed for the joint so that the said joint occupies the top or apex thereof-The
tiles are preferably arranged so that they break bond, that is to say, so that the
joints are alternately placed and are not in continuous lines.
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 :-
First Forming and fixing Roofing tiles so that the joints between the sides of
adjacent tiles are at the apex or highest part of corrugations or ridges formed at
the junctions of the tiles substantially as hereinbefore described.

page_text: Second In roofing tiles, forming them with grooves or water channels in or
between the meeting faces of their sides, and so that the joints between the sides of
adjacents tiles are at the apex or highest part of corrugations or ridges formed at
the junctions of the tiles, substantially as hereinbefore described.
Third In roofing tiles, forming them with grooves or waterchannels in or
between the meeting faces of their sides, and with lips for directing water into
the said channels, and so that the joints of adjacent tiles are at the apex or highest.
part of corrugations or ridges formed at the junctions of the tiles, substantially as
hereinbefore described.
