IMPROVEMENTS IN TILES
Year: 1877

page_text: LETTERS PATENT to Richard Cosslett, the younger, of Elgin Park, Redland,
Bristol, for the Invention of "IMPROVEMENTS IN TILES."
Sealed the 2nd April 1878, and dated the 6th December 1877.
PROVISIONAL SPECIFICATION left by the said Richard Cosslett at the
Office of the Commissioners of Patents on the 6th December 1877.
RICHARD COSSLETT, the younger, of Elgin Park, Redland, Bristol. "IMPROVE-
MENTS IN TILES."
My Invention relates to tiles for roofing, and consists of an improved construction
and arrangement whereby I secure an equal lap throughout the whole of the side
and bottom respectively of the tile, without the necessity for truncating the tiles at
the corners, so that the whole width of the tile overlaps at the bottom, and the
whole length of the tile overlaps at the side of the adjoining tiles.
In carrying out my Invention I construct the tiles of a rhomboidal form, with
taper rolls, so that the rolls and fillet at the side may overlap without removing the
corners; or I construct the tiles themselves of a taper form, and arrange the alternate
tiles with their taper in opposite directions, the respective tiles being provided with
suitable rolls and fillets to interlock the one with the other.
The rolls and fillets may be made of any convenient sectional form.

MENTS IN TILES."
"IMPROVE-
My aforesaid Invention relates to tiles for roofing, and consists of an improved
construction and arrangement whereby I secure an equal lap throughout the whole
of the side (A) and bottom (B) respectively of the tile, without the necessity for
truncating the tiles at the corners (D) so that the whole width of the tile overlaps at
the bottom (B,) and the whole length of the tile overlaps at the side A of the
adjoining tiles.
In carrying out my Invention I construct the tiles of a rhomboidal form (sec
Fig. 1), with taper rolls (E) so that the rolls and fillet at the side A may overlap
without removing the corners (D); or I construct the tiles themselves of a taper form,
and arrange the alternate tiles with their taper in opposite directions, the respective
tiles being provided with suitable rolls and fillets to interlock the one with the
other.
The rolls and fillets may be made of any convenient sectional form.
Fig. 1 in said Drawings represents a plan view of my improved construction and
arrangement of tiles.
Fig. 2, end view or section.
Figs. 3, 4, 5, and 0, end views of my improved tiles, constructed with the rolls and
fillets of other sectional forms than shown by Fig. 2.
The tiles are constructed, as shewn in the Drawings, with the rolls and fillets
interlocking at the one with the other, so that by this Invention I secure the
overlapping of the whole width of the tile at the bottom B, and the overlapping of
the whole length of the tile at the side of the adjoining tile A.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the said Invention of "Improvements in
Tiles," consisting in the peculiar adaptation of fillets and rhomboidal-form rolls,
interlocking at the corners, substantially as herein-before set forth and described, and
illustrated by the accompanying Drawings.
In witness whereof, I, the said Richard Cosslett, the younger, have hereunto
set my hand and seal, this Third day of June, in the year of our Lord
One thousand eight hundred and seventy-eight.
