PROVISIONAL SPECIFICATION.
Improved Compounds for Paving or Covering Roads, Paths, or Floors,
and for Manufacture of Paving Bricks or Blocks.
We, WILLIAM WALTER HEWITT, Knockhall Lodge, Greenhithe, Kent,
Engineer and ALFRED SUART, 32 Great Saint Helens, London, Shipowner, do
hereby declare the nature of this inventior to be as follows :-
In the Specification to Patent No. 9436 of 1886 is described a composition for
paving or covering roads and paths and for the manufacture of paving bricks or
blocks, consisting of granulated cork made up with bituminous material. The present
invention relates to a composition for covering roads or paths and for the manu-
facture of bricks or blocks which, while it presents an elastic upper surface such as
would result from the use of cork, consists either entirely of cheaper material or of
cheaper material arranged in the lower part of the paving or of the brick or block.
For manufacturing a brick or block of the latter kind the mould is first charged
preferably to more than half its depth with a mixture of breeze, gravel; tan, bark,
or the like with bituminous material, and the rest of the mould being filled with the
mixture of granulated cork and bituminous matter, the whole is compressed, and
allowed to set, whereupon the brick or block can be removed from the mould. In
like manner, in forming the surface of a road path or floor, the mixture of breeze,
gravel, tan or bark with bituminous matter is first laid to a certain thickness on the
concrete foundation and then the mixture of granulated cork and bituminous matter
which is to form the upper surface is laid upon the former, and the whole is com-
pressed by ramming or rolling. For the sake of economy, leather, ground or in
small fragments, may be substituted for the granulated cork.

COMPLETE SPECIFICATION.
Improved Compounds for Paving or Covering Roads, Paths, or Floors,
and for Manufacture of Paving Bricks or Blocks.
We, WILLIAM WALTER HEWITT, Knockhall Lodge, Greenhithe,, Kent,
Engineer and ALFRED SUART, 32, Great Saint Helens, London, Shipowner, 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 :-
In the Specification to Patent No. 9436 of 1886 is described a composition for
paving or covering roads and paths and for the manufacture of paving bricks or
blocks consisting of granulated cork made up with bituminous material. The
present invention relates to a composition for covering roads or paths and for the
manufacture of bricks or blocks which, while it presents an elastic upper surface
such as would result from the use of cork, consists either entirely of cheaper material
or of cheaper material arranged in the lower part of the paving or of the brick or
block. For manufacturing a brick or block of the latter kind, the mould is first
charged, preferably to more than half its depth, with a heated mixture of bitumen
with cheap material such as breeze, gravel, spent tan, bark, sawdust or the like.
The rest of the mould is filled with the mixture of granulated cork and
bituminous matter, the whole is compressed, and allowed to set, whereupon the brick

containing the cork being set uppermost. In like manner, in forming the surface
of a road, path or floor, the mixture of the cheap material with bituminous
matter is first laid to a certain thickness on the concrete or other foundation, and
then the mixture of granulated cork and bituminous matter, which is to form the
upper surface, is laid upon the former, and the whole is compressed by ramming or
rolling. For the sake of economy, leather, ground, or in small fragments, may be
substituted partially or wholly for the granulated cork.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A compound for paving consisting of bituminous material mixed with a lower
layer of gravel or like cheap material and with an upper layer of granulated
cork.
2. A modified paving compound in which leather ground or in small fragments is
substituted partially or wholly for the granulated cork.
Dated this 26th day of January 1893.
