PROVISIONAL SPECIFICATION.
Improvements in Interlocking Roofing Tiles having the appearance
of Flat Tiles.
I WALTER HERNAMAN WOOLER of The Chalet, Weston super Mare in the
County of Somerset Architect do hereby declare the nature of this invention to be
as follows:
A method of interlocking tiles by means of grooves & fillets so as to give the
appearance of plain or flat tiles on the roof. This is done by raising the bed of
the tile and making depressions on the underside so as to equalise the thickness.
At the sides there are interlocking fillets and grooves the full length of the tile to
the bottom carrying any drain water onto the tiles below. Along the lower part
of the tiles on the underside is a fillet which dips into the groove along the top of
the tile below on the upper surface and beyond this is a projecting lip which
overlaps the plain surface of the tile below and on the underside of this lip is a
small groove to prevent capillary attraction. The water is thus carried down over
the plain surfaces of the tiles and any water getting into the side joints is carried
down the side groove on to the tile below as aforesaid.
Fig. 1 is a plan of the upper side of the tile.
Fig. 2 is a plan of the underside.
Fig. 3 is a horizontal section from side to side.
Fig. 4 is an upright section from top to bottom.

Improvements in Interlocking Roofing Tiles having the appearance
of Flat Tiles.
I WALTER HERNAMAN WOOLER of The Châlet Weston super Mare in the
County of Somerset Architect & 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 :-
A method of interlocking tiles by means of grooves and fillets so as to give the
appearance of plain or flat tiles on the roof. This is done by raising the bed of
the tile and making depressions on the underside so as to equalise the thickness.
At the sides there are interlocking fillets and grooves the full length of the tiles
to the bottom, carrying any water beating in under onto the tiles below. Along
the lower part of the tile on the underside is a fillet which dips into the groove
along the top of the tile below; on the upper surface and beyond this fillet is
a projecting lip which overlaps the plain surface of the tile below.
Figure 1 shows the upper surface of the tile.
a is the groove running along the top of the tile.
6 is the interlocking groove and fillet at the side and
c is the flat surface.
Figure 2 shows the underside of the tile.
is the fillet at the lower part of the tile which interlocks with the groove a

page_text: ffff represent the depressions on the underside of the tile to equalise its
thickness for producing the flat surface above.
g is a projecting lip which overlaps the plain surface of the tile below.
hh are the nibs for hanging the tiles upon the battens or by perforated
projections in the groove along the top of the tile these tiles may be nailed
to the battens.
Figure 3 is a section across the tile.
Figure 4 is a section from top to bottom.
The letters in Figures 3 and 4 refer to the same parts as in Figures 1 and 2.
Figures 1, 2, 3 and 4 fully describe the several parts and nature of the invention
for this final Specification and Figure 5 in the drawing attached to the Provisional
Specification shows the upper surface of the tiles when laid in mass. Figure 6 on
the same sheet shows the underside of the tiles when laid.
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
An improvement in interlocking tiles by giving them an appearance of flat tiles
when laid, thus doing away with all the more or less unsightly external projec-
tions of interlocking tiles, as described.
