COMPLETE SPECIFICATION.
Improvements in and relating to Wall, Ceiling, and other Tiles.
We, WILLIAM HENRY GODWIN, trading as William Godwin & Son, of Lugwar-
dine Works, Withington, near Hereford, Encaustic and Art Tile Manufacturer,
and THOMAS PICKERILL, of 1, Montrose Villas, Bartonsham, Hereford, Manager
of Tile Works, 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:—
This invention relates to improvements in the preparation and formation of the
backs of wall, ceiling, and other tiles, the object of the invention being to insure
perfect security of the said tiles against displacement when fixed in cement or
other suitable material.
When tiles of ordinary manufacture are fixed on walls, ceilings, or other sur-
faces, they are apt from various causes to eventually become loose and liable to
fall out of their places, but this liability is entirely obviated by our invention.
In order to carry out this invention we provide tiles of the usual form and size,
except that on the back of each tile we provide one or more recesses or sunk
portions, of any convenient size, depth and shape, but preferably circular. These
sunken portions may be of a depth of one eighth of an inch, or thereabouts,
more or less as may be convenient. In the centre of this sunken portion we
provide an undercut or tapering button, made of clay or other convenient material,
and securely fixed to the back of the tile by an imperishable medium, consisting
preferably of an admixture comprising ground flint red lead borax whiting and
glue. This admixture is applied to the back of the button by means of a brush
and the button is then pressed on the back of the tile before it goes through the
glaze kilu, the action of the fire produces an indestructible enamel rendering it
impossible to remove the button without breaking the tile. The face of this said
tapering button being Hush with the face of the back of the tile, thus preventing
any difficulty in manipulating when fixing the said tiles, and at the same time
giving protection to the aforesaid button.
Also the recess being of greater diameter than the button, gives a much better
opportunity for the cement used in fixing, to take a more tenacious grip of the
tile, and the undercut button or buttons which form the key, whilst the fixing
may be proceeded with as in the case of an ordinary plain back tile. At the
same time by the use of this improvement a great saving of labour and material
is effected, and consequently of cost.
In order that this invention may be readily understood, reference is made to the
accompanying drawings in which Fig. 1, represents an elevation, or view of the back
of a tile having one of said buttons as herein before described, Fig. 2, being a section
of the same. Figs 3 & 5 are elevations or back views of tiles having two or
three (or more) of said recesses and buttons respectively, Fig. 4 being a section
taken through two of the said buttons. In these several views A A is the tile,
having on its back surface at B. recesses C C in the centre of which are fixed
the undercut buttons D D the surface of which is level or flush with the surface B
of the back of the tile.

page_text: Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is;-
1. In wall, ceiling, or other tiles, the provision of a recess, or recesses on the
back surface, having an undercut or tapering button or buttons, securely fixed
in the recess or recesses, substantially as and for the purpose herein set forth
and described and illustrated by the accompanying drawings.
2. The application of this invention to any form or kind of tiles, for walls,
ceilings or other surfaces, substantially as and for the purpose herein set forth
and described and illustrated by the accompanying drawings.
Dated this 28th day of October 1898.
