An Improved Composition for Use on Streets, Roads, Pavements,
and the like, and on the Surfaces of Wood and Metal.

I SIDNEY PARNELL DAVIES of 11 Queensdown Road Clapton in the County of
Middlesex Gentleman do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a composition for use on streets roads
pavements and other like surfaces of all descriptions that shall be comparatively if not
absolutely noiseless that shall afford a good foothold for horses and other animals. that
shall suffer very little attrition and that shall be impervious to moisture. This
composition can also be applied to the surfaces of wood and metal for preservative
purposes.
To carry out this object tar or pitch and perhaps preferably coal tar in any desired
quantity is boiled in a suitable vessel or apparatus preferably it may be by the heat
of steam and this boiling is continued say for from two to four hours until the same
is pure that is until all the volatile ingredients and chemical constituents therein say
for example ammonia naphtha sulphur and the like have been evaporated and expelled
therefrom. Retorted shale or the residue or ash of shale that has been treated in a
retort or the like or it may be calcined coal or the residue or ash of coal that has
been burnt in any desired quantity is reduced to a fine impalpable powder and is
added to the purified tar or pitch in about equal quantities therewith or in other
desired proportions while the same is at boiling heat or thereabouts. The combined
mass is then kept at this boiling heat or thereabouts for a further period of say from
two to four hours being agitated or stirred together all the time until it is thoroughly
and completely amalgamated and combined and has attained the desired condition and
consistence when it can be allowed or caused to cool down if desired in any suitable
receptacles or otherwise and is ready for use.
When this composition is to be applied to macadamized or similar roads a certain
quantity thereof in an hot molten state is poured on and over the metal in situ to bind
the same together when this surface can be rolled. On the surface so prepared a
layer of gravel or very fine small metal of the desired thickness similarly treated with
the composition can be placed and then rolled. Above all a thin layer of the
composition can be similarly placed and then rolled.
When this composition is to be applied to streets or the like that have been already
paved with wooden blocks the surface of the same having been properly cleaned and
dried can very conveniently first be treated with the purified tar or pitch in an hot
molten state and then a thin layer of the composition in an hot molten state is placed
hereover and can be rolled if desired.
When the street or the like has not been already paved with wooden blocks it may
generally be expedient to lay a foundation for the same by a layer of broken stone
netal whereon is poured this composition to bind the same together and thereabove
o place a layer of gravel or very fine small metal also bound together by this
omposition and having duly rolled the same to place the wooden blocks upon this

page_text: surface with a very small space between each two adjacent blocks and to fill up all
these interstices with the composition and then to proceed as aforesaid.
In the same manner this composition can be applied to streets or the like paved
with other blocks as also to pavements and other like surfaces.
When this composition is to be applied to the surfaces of wood or metal for
preservative purposes it is so applied by a brush or the like it may be in the same
manner as paint would be applied but obviously only while in an hot and molten and
liquid or semi-liquid state.

New South Wales, Master Mariner...
I SIDNEY PARNELL DAVIES of 11 Queensdown Road Clapton in the County of
Middlesex Gentleman 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:-
The object of this invention is to provide a composition for use on streets roads
pavements and other like surfaces of all descriptions that shall have amongst others
the following advantages and excellences that is to say :-it shall be comparatively
even if not absolutely noiseless-it shall afford an extremely good foothold for horses
and other animals-it will suffer comparatively very little attrition-and it will be
highly impervious to moisture. This composition can also most effectively be applied
to the surfaces of wood and metal for preservative purposes.
To carry out this object I take tar or pitch and perhaps preferably coal tar in any.
desired quantity and I boil the same in a suitable vessel or apparatus preferably it
may be by the heat of steam and this boiling at a temperature say of about
350° Fahrenheit is continued for a period of from two to four hours or it may be
more until this tar or pitch is pure or that is to say until all the volatile ingredients
and chemical constituents therein say for example ammonia naphtha sulphur and the
like have been evaporated and expelled therefrom and the pure tar or pitch will have
a specific gravity of 1-261 or thereabouts. Retorted shale or the residue or ash of
shale that has been treated in a retort or the like or it may be calcined coal or the
residue or ash of coal that has been burnt in any desired quantity is reduced to a fine
impalpable powder in any convenient manner and by any suitable appliances and is
added to the purified tar or pitch in about equal quantities therewith or thereabouts
while the same is at the boiling heat herein before mentioned. The combined mass is
then kept at this same boiling heat or thereabouts for a further period of from two
to four hours being agitated or stirred together all the time until it is thoroughly
and completely amalgamated and combined and has attained the desired condition
and consistence having about the same specific gravity as is hereinbefore mentioned
when it can be allowed or caused to cool down if desired in any suitable receptacles
or otherwise and is ready for use.
When this composition so made and created as is herein before described is to be
applied to macadamized or similar roads a certain desired quantity thereof in an hot
molten state is poured on and all over the metal in situ to bind the same together

can he placed and duly rolled. Above all a thin layer of the composition can be.
similarly placed and then duly rolled.
When this composition so made and created as is hereinbefore described is to be
applied to streets or the like that have been already paved with wooden blocks the.
surface of the same having been properly cleaned and dried can very conveniently
first be treated with the purified tar or pitch herein before described in an hot molten
state and then a thin layer of the composition in an hot molten state is placed:
thereover and can if desired be duly rolled.
When the street or the like has not been already paved with wooden blocks it may
generally be expedient to lay a foundation for the same by a layer of broken stone.
metal whereon this composition so made and created as is hereinbefore described in an
hot molten state is poured in a certain desired quantity to bind the same together and
thereabove to place a layer of gravel or very fine small metal also similarly bound
together by this composition and having if desired duly rolled the same to place in.
the ordinary manner the wooden blocks upon this surface but most conveniently and
preferably with a very small space between each two adjacent blocks and to fill up all
these interstices with the composition and then to proceed as is hereinbefore.
described.
In the same or in a somewhat similar manner this composition so made and created
as is hereinbefore described can be applied to streets or the like which have been or
are to be paved with other blocks as also to pavements and other like surfaces.
When this composition so made and created as is herein before described is to be
applied to and on the surfaces of wood and metal for preservative purposes it is or
may be so applied by a brush or the like it may be in the same or in a somewhat.
similar manner as paint would be applied but obviously only while in an hot and.
molten and liquid or semi-liquid state.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
The improved composition for use on streets roads pavements and the like and on
the surfaces of wood and metal substantially as bereinbefore described and set forth.
