Improvements in Tiles and Structures in which they are used.
1, WILLIAM LINDSAY' of 23 Queen Anne's Gate in the City of Westminster
Engineer do hereby déclare the nature of this invention to be as follows:----
According to this invention I make tiles having on two opposite faces dove tailed
grooves or recesses to receive plaster or other material. Another pair of opposite faces
are notched to receive iron supports, as hereinafter described, and the remaining
pair of opposite faces one is furnished with a projection and the other with a recess
which fit corresponding 'recesses and projections on the adjacent tiles.
In making a partition wall or like structure I proceed as follows:-
At suitable intervals apart I place uprights made of iron whose transverse section lis
a cross: Between these uprights the tiles are inserted each of their notclied ends
receiving one web of an upright their ends abutting against the other webs. The two
faces of the partition so made are then plastered over, the plaster being retained in the
dove-tail grooves on the faces of the tiles.'
In place of having an upright between each row of tiles several rows may be placed
between each pair of uprights, the bonding of the tiles together by means of the
projections and recesses on their adjacent faces giving sufficient strength to allow of
this being done in many cases.

Improvements in Tiles and Structures in which they are used.
1, WILLIAM LINDSAY of 23 Queen Anne's Gate in the City of Westminster
Engineer, 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 :-
☑-
According to this invention I make tiles having on two opposite faces dove tailed
grooves or recesses to receive plaster or other material. Another pair of opposite
faces are notched to receive iron supports, as hereinafter described, and of the
remaining pair of opposite faces one is furnished with a projection and the other with
a recess which fit corresponding recesses and projections on the adjacent tiles.
In making a partition wall or like structure I proceed as follows:
At suitable intervals apart I place uprights made of iron whose transverse section is
a cross. Between these uprights the tiles are inserted each of their notched ends
receiving one web of an upright their ends abutting against the other webs. The two
faces of the partition so made are then plastered over, the plaster being retained in the
dove-tail grooves on the faces of the tiles.
In place of having an upright between each row of tiles several rows may be placed
between each pair of uprights, the bonding of the tiles together by means of the pro-
jections and recesses on their adjacent faces giving sufficient strength to allow of this
being done in many cases.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.

page_text: after the tiles have been built together to form a wall or partition. b are notches to
receive the webs of uprights. c c are interlocking projections and grooves on the
remaining faces of the tiles.
Figure 3 is a horizontal section of a wall or partition built with my improved tiles.
dd are iron uprights of cross section set up at convenient intervals.
In the case
represented by this figure there is space to receive two tiles between the uprights.
Each tile is notched at one end only and the tiles are not of the same length so that
they break joint in the successive courses. There are interlocking projections and
recesses where the tiles.meet end to end. The line shews the face of the plaster
with which the wall or partition is covered.
Figure 4 shews transverse sections of similar tiles adapted to be laid horizontally
to form a ceiling and to carry a concrete floor. The dovetail grooves on the upper
face are made much deeper in this case.
Figure 5 is a side elevation of a part of one of these tiles with an iron joist in
section.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. Tiles substantially as described having two opposite faces with dovetail grooves
or recesses to receive plaster or other material and two other opposite faces with inter-
locking projections and recesses and with one or both of the remaining faces notched
to receive the web of an iron support.
2. A wall or structure consisting of tiles such as described combined in the manner
described with uprights of a cross section.
