PROVISIONAL SPECIFICATION left by the said Henry Hall at the Office
of the Commissioners of Patents on the 1st September 1881.
:
HENRY HALL, of Saint Paneras, in the County of Middlesex. "AN IMPROVE-
MENT IN TILES FOR LINING OR FACING WALLS AND OTHER SURFACES."
My Invention relates to tiles for lining or facing walls and other surfaces, and
the Invention consists in forming each tile with a lip or flange along one edge, the
said lip or flange being rebated or depressed below the face of the tile to an extent
equal to or rather greater than the thickness of the body portion of the tile. The said
lip or flange is parallel with the body of the tile, so that when applied upon a wall
or other surface the body of one tile will overlap and cover the flange of the tile
next below or adjacent and will thus entirely conceal the nails or screws used to
fix it, as hereafter described.
The back surface of the lip or flange of the tile projects a corresponding
distance in rear of the back of the body portion, and is in a plane parallel
with that of the body of the tile, so as to be readily applied against a wall
or other flat surface without requiring special care to ensure the faces of all the
tiles lying flush with one another. Holes are made in this lip or flange for nails
or screws, by which the tile may be securely fixed either to brick, stone, or
woodwork, these fastenings being entirely concealed by the body of the adjacent
tile, which overlaps and covers them. A shallow groove is made in the back
surface of the body portion of the tile to make room for the screw or nail heads
and prevent contact of the body of the tile therewith. Besides being secured by
nails or screws the body portion of the tile would also be bedded in mortar or
cement upon the flange of the adjacent tile, whereby a thoroughly waterproof joint
is obtained.
The tiles may be white or colored, glazed or not, and may have a raised or other
pattern upon the face. The body portion of the tile may be rectangular to
course with brickwork, or may be hexagonal, or of any other suitable shape to form
a pattern.

HENRY HALL, of Saint Pancras, in the County of Middlesex. "AN IMPROVE-
MENT IN TILES FOR LINING OR FACING WALLS AND OTHER SURFACES."
My Invention relates to tiles for lining or facing walls and other surfaces, and
the Invention consists in forming each tile with a lip or flange along one edge,
the said lip or flange being rebated or depressed below the face of the tile to an
extent rather greater than the thickness of the body portion of the tile. The said
lip or flange is parallel with the body of the tile, so that when applied upon a wall
or other surface the body of one tile will overlap and cover the flange of the tile
next below or adjacent, and will thus entirely conceal the nails or screws used to
fix it, as hereafter described.
The back surface of the lip or flange of the tile projects a corresponding
distance in rear of the back of the body portion and is in a plane parallel with
that of the body of the tile, so as to be readily applied against a wall or
other flat surface without requiring special care to ensure the faces of all the
tiles lying flush with one another. Holes are made in this lip or flange for nails
or screws, by which the tile may be securely fixed either to brick, stone, or
woodwork, these fastenings being entirely concealed by the body of the adjacent
tile, which overlaps and covers them. Besides being secured by nails or screws
the body portion of the tile will also be bedded in mortar or cement upon
the flange of the adjacent tile, whereby a thoroughly waterproof joint is
obtained.
The tiles may be white or colored, glazed or not, and may have a raised or other
pattern upon the face. The body portion of the tile may be rectangular to
course with brickwork, or may be bexagonal, or of any other suitable shape to form
of oblong and of square form.
Figure 1 is a front view, Figure 2 a vertical section, and Figure 3 a back view
of an oblong tile; Figures 4, 5, and 6 are similar views of a square tile.
A is the body portion of the tile, the face a of which may be ornamented in
any desired manner; B is the lip or flange moulded in one with the body
portion A, its rear face b being in a plane parallel to that of the face a.
The body
portion A and the flange B are each rather less than half the total thickness of the
tile measured from the front face a to the back face b, and they are preferably
made of the sectional form shown, although I do not restrict myself. thereto. I
prefer that the lower edge a¹ of the body part A should be slightly bevelled, as
shown, and the upper edge a² of the body part correspondingly under cut and the
flange B formed with a shoulder 62, so that when the tiles are affixed to the wall
they will overlap, as shown in dotted lines, and the lower edge of each tile will
bed against the shoulder b³ of the adjacent tile and be securely held by the bevelled
joint with its face flush with the face of the adjacent tile. c are the holes in the
flange B for the nails or screws by which the tiles are fixed.
In Figures 1, 2, and 3, the flange B is almost equal in width to the body part A,
and the body part A is therefore bedded wholly upon the flange of the next tile, as
above described, but I do not limit myself to this arrangement, as the flange may
be narrow in proportion to the tile, so that the tiles overlap to a comparatively
slight extent, as shown in Figures 4, 5, 6, in which case the body part of the tile

page_text: would be made thicker or provided with projections or feet at back, as at a³, to
take a bearing on the surface of the wall and form a key for the bed of mortar or
cement.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
berein before in part recited Letters Patent is,-
1st. Making tiles with a rebated lip or flange projecting from one edge of the
tile, the back surface of the flange being parallel to the front face of the tile, so
that the body portion of one tile will overlap the lip or flange of the adjacent
tile, substantially as and for the purpose herein described.
2nd. The improved tiling, substantially as herein shown and described.
In witness whereof, I, the said Henry Hall, have hereunto set my hand
and seal, this Twenty-eighth day of February, in the year of our Lord
One thousand eight hundred and eighty two.
