Improvements in or connected with Bricks for Building Purposes.
We, JAMES HOLROYD, Ceramist, and ROBERT BOND, Potter, both of Burmantofts,
Leeds, in the County of York, do hereby declare the nature of this invention
to be as follows:-
This invention refers particularly to bricks which are glazed on opposite
sides, though it is also applicable to ordinary bricks. Much difficulty bas
hitherto been experienced in effecting this double glazing, as the first glazed
surface is liable to injury during the preparation of the second surface.
According to our invention we construct the brick in two portions, the
divisions being formed longitudinally down the brick, and the adjacent edges
of the two portions are formed with overlaps which interlock with each other
when they are brought together. This construction of the brick in two portions,
enables the glazed surfaces to be prepared and fired on each portion separately,
thus enabling both surfaces to be efficiently glazed without injury.
The two portions above described are subsequently joined together; or. when
used in building they can be connected with mortar, and thus a double glazed
wall may be readily erected.
In forming bricks with glazed ends, the interlocking division above referred
to would be formed transversely across the brick.
When building a single brick wall, the bricklayer is enabled to correct the
line on one face of the wall without creating an error in the line of the other
face; and when the brick is used as a header, the interlocking division enables
its length to be adjusted, thus obviating the frequent necessity of breaking a
brick so as to make both ends fit.

Improvements in or connected with Bricks for Building Purposes.
We, JAMES HOLROYD, Ceramist, and ROBERT BOND, Potter, both of Burmantofts,
Leeds, in the County of York, 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 refers particularly to bricks which are glazed on opposite ends or
sides, though it is also applicable to ordinary bricks. Much difficulty has

page_text: hitherto been experienced in effecting this double glazing, as the first glazed
surface is liable to injury during the preparation of the second surface.
According to our invention, we construct the brick in two portions, having the
adjacent parts of the two portions formed with overlaps which interlock with
each other when they are brought together. This construction of the brick, in
two portions, enables the glazed surfaces to be prepared and fired on each portion
separately, thus enabling both surfaces to be efficiently glazed without injury;
and further by our invention we produce bricks which are particularly adapted
to be used in the construction of 4½ inch and 9 inch walls, having glazed surfaces,
because the glazed surfaces of each brick are capable of independent adjustment.
In order that our invention may be readily understood, we will describe same
with reference to the accompanying drawing, in which Figure 1 shows in side
elevation a brick, transversely divided. Figures 2 and 3 are plan views of the
two portions, which constitute the brick, shown in Figure, 1. Figure 4 shows
in end elevation a brick longitudinally divided; and Figures 5 and are part
plan views of the two portions, which constitute the brick, shown in Figure 4.
Referring particularly to Figures 1, 2 and 3, the brick, which is transversely
divided, is constructed in two portions A and B, the end surfaces A¹ and B¹ of
which may be glazed in the ordinary manner. The adjacent parts C and D of
the portions A and B are formed of an interlocking nature, as clearly shown in
the drawings; and the parts C and D may be made with apertures E E, to
enable a wall in the course of construction to be grouted, if desired.
Referring particularly to Figures 4, 5 and 6, a brick is illustrated which is
longitudinally divided into two portions I and G, the side surfaces F¹ and G¹ of
which may be glazed; and the adjacent parts H and J formed of an interlocking
nature as shown in the drawing. Similar apertures such as E E shown in
Figures 1, 2 and 3 may be provided, for the purpose of grouting.
Bricks constructed according to our invention are particularly convenient for
building purposes; the portions being connected together and to one another by
mortar or cement in the ordinary way, and when used in building a wall having
both surfaces glazed, the bricklayer is enabled to correct the line on one face of
the wall without creating an error in the line of the other face; and when the
brick is used as a header the interlocking division enables its length to be
adjusted, thus obviating the frequent necessity of breaking a brick so as to make
both ends fit:
Having now particularly described and 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 bricks, divided in two portions, the adjacent parts being
formed of an interlocking nature, substantially as set forth.
2. The general construction of bricks, substantially as and for the purposes
hereinbefore described with reference to Figures 1, 2 and 3 of the accompanying
drawing.
3. The general construction of bricks substantially as and for the purposes
herein before described with reference to Figures 4, 5 and 6 of the accompanying
drawing.
