PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Compositions suitable for
Paving, Building, Pipe Jointing, and other like Purposes.
I, WILLIAM SYKES, of the Town Hall, Walham Green, in the County of
Middlesex, Surveyor, do hereby declare the nature of this invention to be as
follows
This invention relates to the manufacture of new or improved compositions
suitable for paving, building, pipe jointing and other like purposes.
According thereto I intimately mix together Archangel tar and Portland cement,
say about one gallon of tar to about two bushels of cement or thereabouts. The
mixture is worked up, by stirring or otherwise agitating it, into a thick plastic
state and formed into blocks of suitable shape, or laid in position and brought to
a smooth and even surface by means of hot irons and rammers as in the ordinary
way of laying asphalt. Preferably, in order to secure the most satisfactory results
the mixture before application, and whilst being worked up, is placed in a cauldron
or other suitable vessel and highly heated or boiled therein.
A composition having a more pliable surface is obtained by using Stockholm
tar instead of Archangel tar and mixing the same in about the same proportions
as hereinbefore described with Portland cement.
Where the composition is required to have a better gripping surface so as to
afford a firmer hold for horse hoofs than composition made as hereinbefore described
I incorporate with the same finely divided or gritty material, such as sawdust
using preferably hard wood sawdust.
A suitable composition of this kind may be made by incorporating or mixing
together say about one gallon of Stockholm or Archangel tar, about two bushels
of Portland cement, and about one and a half bushels of hard wood sawdust, with
or without an addition of other substance or substances such as sand. The sawdust
is preferably first well incorporated with the tar, the cement is then added, and the.
whole heated or boiled and stirred to render the mixture thoroughly uniform. The
mixture thus obtained can then be formed into blocks of suitable shape, or be laid in
position and brought to a smooth and even surface as before. When the composition
is intended for use in jointing pipes, as for instance pipes which have parts moulded
on, or otherwise applied to, their ends so as to permit of the pipes being screwed
together, the same may be formed either with Archangel or Stockholm tar, using nay
about one gallon of tar and mixing the same with about two bushels of Portland
cement or thereabouts, as hereinbefore described, but preferably forming the mixture
without the application of heat.
Instead of employing Portland cement, in the manufacture of composition
according to this invention, I may employ Roman cement, or other suitable cement
or lime.
Such compositions are very suitable for use after the manner of asphalt for
paving roadways and footways, or for forming damp courses, or for blocks or
bricks to be used for paving or for building brickwork in damp soil.

Improvements in the Manufacture of Compositions suitable for
Paving, Building, Pipe Jointing, and other like Purposes.
I, WILLIAM SYKES, formerly of the Town Hall, Walham Green, in the
County of Middlesex, but now of 18 New Bridge Street, Blackfriars, in the City
of London, Surveyor, 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 relates to the manufacture of new or improved compositions
.suitable for sewer pipe jointing, paving, building, and other like purposes.
According thereto I intimately mix together Archangel tar and Portland cement,
say about one gallon of tar to about two bushels of cement or thereabouts, the
mixture being worked up, by stirring or otherwise agitating it, into a thick plastic
state. For pipe jointing, the resulting composition is used in its plastic Istate, and
may be applied in the form of a ring or fillet to one of the pipes to be jointed, as
for instance to the spigot end of such pipe, and then be compressed by bringing the
ends of the pipes to be jointed, together. After a time, the composition will set to
a hard mass and form an effective gas and watertight joint. When the composition
is to be used for paving or building purposes, it may be first formed into blocks.
of suitable shape, or it may be laid in position, in the case of paving, on a concrete
or other hard-and-flat-bed-and-be-brought-to-a-smooth and even surface by means
of hot irons and rammers as in the ordinary way of laying asphalt. In order to
secure the most satisfactory results when the composition is to be used for paving,
building and like purposes, the mixture before application, and whilst being worked
up, is preferably placed in a cauldron or other suitable vessel and heated to a
sufficient temperature to bring it into a semi-liquid condition so as to facilitate its
being spread over the surface to which it is to be applied. When the composition
is to be used for jointing sewer pipes, it is preferably made without the application
of heat.
A composition having a more pliable surface or nature and suitable for either of
the purposes mentioned, can be obtained by using Stockholm tar instead of
Archangel tar, and mixing it in about the same proportions, as hereinbefore
described, with Portland cement.
Where the composition is to be used for paving purposes and is required to
provide a better gripping surface, so as to afford a firmer hold for horses' hoofs
than composition made as hereinbefore described, I incorporate with the tar and
cement, finely divided material, such as sawdust, using preferably hard wood
sawdust.
A suitable composition of this kind can be made by incorporating or mixing
together, say about two gallons of Stockholm or Archangel tar, about two bushels
of Portland cement, and about one and a half bushels of hard wood sawdust, with
or without an addition of other finely divided substance or substances such as sand,
of which say about a half bushel may be used.
The sawdust may be first well incorporated with the tar, the cement then added,
and also the sand, if used, and the whole heated and stirred sufficiently to render
the mixture thoroughly uniform. Or the tar may be first boiled so as to render it
more liquid, and then whilst it is hot, the sawdust is well incorporated with it, the
cement, and also the sand if used, being added gradually during the mixing
process, which is preferably effected without the aid of additional heat. The
mixture thus obtained can be formed into blocks of suitable shape, or it can be
laid in position upon a concrete or other bed and brought to a smooth and even
Burface as before.
Instead of employing Portland cement in the manufacture of compositions
according to this invention, I may employ other suitable cement such as Roman

page_text: cement, or powdered lime either in the caustic or slacked condition, each of these
being used in about the same proportion as the Portland cement hereinbefore
mentioned. It is to be understood that the proportion of tar to cement may be
varied to some extent from that mentioned, according to the condition of the cement.
When the cement is old one gallon of tar to two bushels of cement or thereabout,
will usually be found to give satisfactory results, but when the cement is new a
larger portion of 'tar will be necessary, the proportion in each case being such that
the resulting mixture is of a thick plastic nature at ordinary temperatures and just
after being made.
Compositions such as described are, in addition to the uses already mentioned,
suitable for forming damp courses, and as a cementing material for building brick-
work in damp soil.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The herein described manufacture of a composition suitable for the purposes
mentioned and consisting of Archangel or Stockholm tar and cement such as
Portland or Roman cement or lime as set forth.
2. The herein described manufacture of a composition suitable for paving
purposes, consisting of Archangel or Stockholm tar, Portland or Roman cement or
lime, and finely divided material such as sawdust, with or without an addition of
other finely divided substances such as sand, as set forth.
3. The manufacture as hereinabove described of the compositions referred to in
the preceding claims.
