PROVISIONAL SPECIFICATION.
An Improvement or Improvements in Paving Bricks.
I, JOSEPH HAMBLET, the Younger, of Piercy Blue Brick, Tile and Pipe
Works, West Bromwich, in the County of Stafford Brick Tile and Pipe Manu-
facturer do hereby declare the nature of this invention to be as follows:--
In paving bricks of the ordinary kind the frog, indent, pattern or checkered
surface to form the tread of the brick is made only on one face of the brick so
that when the treading face is worn the paving brick has to be replaced by a
fresh one.
My invention consists in making the frog, indent, pattern or checkered surface
to form the tread on both faces of the paving brick so that the brick can be laid
with either treading face upwards and when one of the treading faces of the paving
brick is worn the brick can be inverted so as to bring its unworn treading face
uppermost and relaid in that position.
I make the frog, indent, pattern or other treading surface on each face of the
brick by pressure after the brick has been moulded.
Paving bricks having treading faces according to my invention are economical in
use inasmuch as their wearing properties are doubled and the cost and carriage of
new paving bricks is dispensed with when one only of the treading faces of the
brick is worn.
My invention may be applied to paving bricks having figured or irregular or
fancy patterns and the patterns generally used on the treading faces of ordinary
paving bricks.
Dated the 18th day of March 1892.

COMPLETE SPECIFICATION.
An Improvement or Improvements in Paving Bricks.
I, JOSEPH HAMBLET the Younger of Piercy Blue Brick, Tile and Pipe
Works, West Bromwich in the County of Stafford, Brick, Tile and Pipe Manu-
facturer, do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
In paving bricks of the ordinary kind the frog, indent, pattern or checkered
surface to form the tread of the brick is made only on one face of the brick so
that when the treading face is worn the paving brick has to be replaced by a
fresh one.
My invention consists in making the frog, indent, pattern or checkered surface
to form the tread on both or opposite faces of the paving brick so that the brick
can be laid with either treading face upwards and when one of the treading faces
of the paving brick is worn the brick can be inverted so as to bring its unworn
treading face uppermost and relaid in that position.
The paving bricks with double treading faces may have the same pattern on both
faces or a different pattern on each face.
I make the frog, indent, pattern, or other treading surface on each face of the
brick by pressure after the brick has been moulded; or the frog, indent or pattern
may be made by the moulding operation.
Figure 1 of the accompanying drawing represents in plan a series of paving

page_text: bricks made according to my invention having the same pattern on both faces;
Figure 2 represents in isometrical perspective and Figure 3 in longitudinal section
one of the said paving bricks Figure 1, drawn to a larger scale. The pattern, frog
or indent on one face a of the brick is marked a' and the pattern, frog or indent on
the opposite face b is marked b².
Figure 4 represents in plan, a series of paving bricks made according to my
invention having different patterns, frogs or indents on their opposite treading
faces; Figure 5 represents in isometrical perspective and Figure in longitudinal
section one of the paving bricks Figure 4, drawn to a larger scale. The pattern
frog or indent on the face e of the brick is marked and the different pattern on
the other face d of the brick is marked d³.
Paving bricks having treading faces according to my invention are economical in
use inasmuch as their wearing properties are doubled and the cost and carriage of
new paving bricks is dispensed with when one only of the treading faces of the
brick is worn, and the shrinking in the course of manufacture is rendered more
uniform and the production of a better shaped brick ensured.
Although I have only represented paving bricks having two kinds of patterns on
their treading faces, yet my invention may be applied to paving bricks having
figured or irregular or fancy patterns and the patterns generally used on the
treading faces of ordinary paving bricks.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as my
invention of "An improvement or improvements in paving bricks :-
"
Making the frog, indent, pattern or checkered surface to form the tread of the
paving brick on both or opposite faces of the said brick so that the brick can be
laid with either treading face upwards and when one of the treading faces is worn,
the brick may be inverted and the unworn treading face brought uppermost and
relaid in that position for use substantially as hereinbefore described and illustrated
in the accompanying drawing.
