PROVISIONAL SPECIFICATION.
Improvements in the Construction of Fire Proof Tile Ceilings,
Partitions, and the like.
We WILLIAM JONES and HENRY JONES both of No. 5 Cyril Road Small Heath,
Birmingham, in the County of Warwick, Art Tile Workers do hereby declare the
nature of this invention to be as follows:-
This invention relates mainly to the construction of fire proof tile ceilings and
similar surfaces, and consists of a novel combination of glazed tiles set up or
mounted with suitable cement on metallic lathing attached to the ceiling joists or
other framing in the manner or by the method now to be described.
For the metallic lathing we prefer to use that known as the patent expanded
metal, but other suitable descriptions of such material may be used to form a strong
key for the cement. The metallic lathing is attached to the joists or other framing
in any usual way but in accordance with this invention, we affix strips of asbestos
to the said joists or framing to form a bed for the metallic lathing.
The glazed tiles used are to be made with dovetailed recesses at the back. The
tiles are affixed to the metallic lathing by covering the backs of the same with
parian cement or other suitable composition, the tiles being then adjusted and
pressed to the metallic lathing. The cement protrudes through the meshes or
insterstices of the metallic lathing, forming when set a strong and rigid
attachment.
In addition to being fire proof, the advantages in appearance and cleanliness
of glazed tiles for such purposes, are utilized in this invention with great lightness
and ease of construction.
By this combination we can construct fire proof ceilings or other surfaces of greater
strength and durability, and with less weight and at less cost than by methods
hitherto in use.

Improvements in the Construction of Fire Proof Tile Ceilings,
Partitions, and the like.
We WILLIAM Jones and Henry JONES both of 5 Cyril Road Small Heath
Birmingham in the County of Warwick Art Tile Workers 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 mainly to the construction of fire proof tile ceilings and
similar surfaces and consists of a novel combination of glazed tiles set up or
mounted with suitable cement on metallic lathing attached to ceiling joists or other
framing in the manner or by the method now to be described.
For the metallic lathing we prefer to use that known as "the patent expanded
metal" but other suitable descriptions of such material may be used to form a

page_text: strong key for the cement. The metallic lathing is attached to the joists or other
framing in any usual way but in accordance with this invention we affix strips of
asbestos to the said joists or framing to form a bed for the metallic lathing.
The glazed tiles used are to be made with dovetailed recesses at the back the
tiles are affixed to the metallic lathing by covering the backs of same with parian
or other suitable cement the tiles being adjusted and pressed to the inetallic lathing
the cement protrudes through the meshes or interstices of the metallic lathing
forming when set a strong and rigid attachment.
In addition to being fireproof the advantage in appearance and cleanliness of
glazed tiles for such purposes are utilised in this invention with great lightness
and ease of construction. By this invention we can construct fire proof ceiling and
the like of greater strength and durability and with less weights and less cost than
by methods hitherto in use.
We will now proceed to fully describe the said invention reference being made
to the two accompanying sheets of drawings.
In these -
Figure 1 Sheet 1 is a view to about one fourth full size looking upwards of a
portion of a ceiling constructed in accordance with our invention part of the tiles
being removed to shew mode of fixing.
Figure 2 Sheet 2 is a vertical section of a part of the same to an enlarged scale
or about full size.
Figure 3 Sheet 2 is a view of the back of one of the tiles shewing the manner
in which the tiles are recessed.
Figure 4 Sheet 1 shews transverse section to a small scale of the general
arrangement in accordance with our invention of ceiling and so forth in
position.
The same letters of reference apply to corresponding parts throughout the
whole of the figures.
In Figures 1. 2 and 3 is shewn the mode in which by preference we adopt in
accordance with our invention in the construction of our improved ceilings.
A. A. are the glazed ceiling tiles of any usual make and finish but the backs of
which are provided with peculiarly shaped recesses. a. a. the opposite pairs forming
dovetails as at a¹ and a². These may run parallel with the sides or diagonally
across the tile or in a circular direction but for strength it is preferred to leave a
margin all round a³ a³. B. B. is the patent expanded metal lathing which is
attached to the joists or other framing b. b. by the staples or by other
devices. This patent expanded metal covers the whole area of the ceiling or other
surface to be tiled and to this we affix and attach the tiles by parian Portland or
other suitable cement C. C. which is mixed to a moderate consistency so as to
protrude through the interstices of the metallic lathing B and overlap the
same as shewn at c. c thus forming when set a rigid and secure key or attach-
ment between the back of the tiles with the dovetailed recesses a. a. and the strips
or filaments of the metallic lathing the latter as shewn in the section Figure 2
lie at an angle of about 45 degrees thus giving a perfectly safe hold.
The patent expanded metal lathing being wholly covered with the cement is quite
proof against any corrosion that may arise at the back of a ceiling or other surface
constructed in accordance with our invention.
Our invention is easily applicable to "coved" ceilings cornices or other curved
work as shewn on the right hand side cf Figure 4 or to framed partitions on
the left hand side in the same figure.
Although the joists or other framing to which the ceilings or other surfaces
are attached are shewn as of wood in the drawings our invention is, as will be
well understood as readily carried into use in connection with wrought iron or other
metallic framing.
In the case of wood joists or other framing we prefer to affix strips D. of asbestos
..or other nonconducting material to the said joists or other framing on which to bed
the metallic lathing."

page_text: It will be obvious that modifications both in the construction of the dovetailed
recesses in the backs of the tiles and of style or construction of the metallic
lathing may be made without departing from the nature of our invention.
Having now particularly ascertained the nature of our said invention and in what
manner the same is to be performed we declare that what we claim is :-
:―
1. The construction of ceilings or other surfaces of glazed tiles cemented to and
in combination with metallic lathing known as "the patent expanded metal'
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
2. The construction of ceilings or other surfaces of glazed tiles so recessed at
the back that the opposite recesses form dovetails as at a a² in combination
with "the patent expanded metal" lathing above described or with any similar
or equivalent metallic lathing affixed substantially as and for the purposes herein
described.
Dated this 11th day of January 1896.
