PROVISIONAL SPECIFICATION.
Improvements in the Fixing of Tiles to Walls, Ceilings, and other
places.
I JOHN DOBBIE of Sheriff Brac, Leith, in the County of Midlothian, North
Britain, Caustic Tile Layer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the fixing of tiles to walls, ceilings and.
other places. In accordance with my invention I form or mould the corners of
the tile with a sunk segmental portion so that when four tiles are fitted together
the segniental portions form a circular recess or sunk portion. Into the said recess
is fitted a small round tile preferably made of majolika. At the junction of the
four corners of the set of tiles, a small hole is left for the passing of a screw nail
into the woodwork behind the tiling. A countersunk hole is left in the centre of
the piece of majolika for the reception of the head of the screwnail so that when
the screw is screwed up it clamps the tiles firmly into position, the piece of majolika
acting as a wide flange to bear against the tiles. The piece of majolika is preferably
of such a thickness at its centre that a space is left in the countersunk hole above
the head of the screwnail; this space I fill up with a tile button cemented in,
thus hiding the screwnail from view. The piece of majolika or other flanging or
clamping piece that is used may be of square or of other shape than found.

COMPLETE SPECIFICATION.
Improvements in the Fixing of Tiles to Walls, Ceilings, and other
places.
I, JOHN DOBBIE, of Sheriff Brac, Leith, in the County of Midlothian, North.
Britain, Caustic Tile Layer, 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 fixing of tiles to walls, ceilings
and other places. In accordance with my invention I form or mould the corners'
of the tile with a sunk segmental portion so that when four tiles are fitted together
the segmental portions form a circular recess or sunk portion. Into the said recess
is fitted a round or other shaped stud preferably made of earthenware or majolica.
At the junction of the four corners of the set of tiles, a small hole is left for the
passing of a screw nail into the wood work or metal work behind the tiling. A
countersunk hole is left in the centre of the stud for the reception of the head of
the screw nail so that when the screw is screwed up clamps the tiles firmly into .
position, the stud acting as a wide flange to bear against the tiles. The stud is
preferably of such a thickness at its centre that a space is left in the countersunk
hole above the head of the screw nail; this space I fill up with a button of
earthenware or majolica cemented in, thus hiding the screw nail from view.
Figure 1 illustrates a plan of a portion of each of four tiles with their corners
bound together in accordance with my said invention.
Figure 2 is a section of the same.
Figure 3 is a plan of the tiling with the button removed.
Figure 4 is a plan of the button detached.
Figures 5, 6, 7, and 8 are modifications hereafter referred to.
As shown more particularly in Figure 3, I form the corners of each of the tiles A,

page_text: with a sunk portion a so as to form a recess for the stud B, which is shewn in
position in sectional view Figure 2. At the junction of the four corners of the set
of tiles is formed a small hole for the passage of a screw nail C. Figure 2, into
the woodwork or other backing D behind the tiling. The countersunk hole in the
stud for the reception of the screw head is of such a depth as to allow of the
insertion of the button E, which completely hides the head of the screw. Any
cementing material may be used between the tiles and the backing D, and also for
the purpose of fixing the stud and the button.
Figure 1 illustrates an ornamental stud and button so that the junction of the
tiles is completely hidden. Thus ordinary iron screws may be used as the heads
are completely covered by the cap E. It will also be seen that by my invention
the button acts as a wide Hange so than the corners of the tiles are secured
firmly.
It is obvious that the recessing of the corners of the tiles might be dispensed
with the button being simply fixed against the face of the tiles.
As a modification 1 may employ the button simply as a cover for the screw head
as shown in Figure 5, the flange of the screw head bearing against the tile.
As shewn in Figures 6 and 7, the tile A is bound up against the backing D
by the metal or other loose washer F and screw C. In this case the stud B is
shewn as a cover for the screw head and is bound thereto in the following
manner :-
The screw head is filed away to the narrow shape shewn in dotted lines Figure 6.
The back of the stud B is formed with a slotted hole C¹ also shewn in dotted
lines Figure 6 to receive the, said head of the screw. The underside around the
said slotted hole of the stud is channelled out so that when the stud is applied to
the tile the head of the screw is received into the said slot of the stud and by
giving the stud a quarter of a turn it is securely locked. The screw and stud may
be cemented up in the same manner as in the preceeding arrangement.
In applying my invention to angle beads of tiling, as shown in Figure 8, I form
the ends of the beads with a semicircular recess so that when the ends of two
beads abut, a hole is formed for the reception of the screw. The hole is formed-
countersunk in a similar manner to that shewn with regard to the countersinking
of the stud in Figure 2, and into the said countersunk portion above the screw
head I fix in the button E, which may be ornamented as shewn, and so as to
completely hide the head of the screw.
do not limit myself to any particular materials of which the studs and buttons
are made, for example the studs might be made of metal as well as earthenware
or majolica.
Also instead of the studs or buttons forming a raised portion of the tiling they
may be made more or less flat with the surface of the tiles.
Also the studs or buttons might be of other shapes such as square, hexagonal,
or of other shape.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, 1 declare that what I
claim is
(1) The mode of fixing tiles to walls, ceilings and other places, substantially as
hereinbefore described and shown in the accompanying drawings.
(2) The stud B and button E, substantially as and for the purposes hereinbefore
described and shown more particularly in Figure 2, or any mere modification of
same such as is shown in Figures 5, 6, 7 & 8 of the accompanying drawings.
(3) The mode of covering the screw head, substantially as and for the purposes
hereinbefore described and shown in the accompanying drawings.
