PROVISIONAL SPECIFICATION left by the said John Macintosh at the
Office of the Commissioners of Patents, with his Petition, on the
4th February 1874.
I, JOHN MACKINTOSH, of Westminster, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ROADS AND WAYS, AND THE MATERIALS USED FOR SUCH
PURPOSES," to be as follows:-
The object of the first part of my Invention is to lessen the expense of
constructing and maintaining roads and ways, also to decrease the mud,
dust, noise, and slipperiness, and consists in covering the concrete with
adhesive bitumen rendering it waterproof by well-known means, over
which is placed coarse cloths saturated with vulcanized solution mixed
with cotton seed, pitch, wood, cork, or fibrous waste dust.

page_text: The second part of my Invention is to lessen the expense of maintaining
macadamised roads, also to decrease the mud, dust, and noise, and
consists in using the mud taken from the roads, which is dried, sifted,
and rendered impervious to moisture by mixing it with waterproof
substances until it becomes a plastic heterogeneous mass, in which state 5
it can be spread on to the roads.
In some cases it is desirable to smooth and waterproof the road with a
coating of adhesive bitumen alone or in combination with felt before
applying the compound.
It will be readily understood that mud dried and waterproofed which 1
is inexpensive, durable, preventing mud and dust, admirably adapted for
covering roads in lieu of broken granite which is rapidly reduced to
mud and dust, causing the employment of men and water carts to
reduce the nuisance, which will be obviated by my Invention, to
which I will give the name of the Macintosh road.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said. John Macintosh in the Great Seal Patent Office
on the 4th August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MACINTOSH, of Westminster, in the County of Middlesex, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of February, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Macintosh, Her special
licence that I, the said John Macintosh, my executors, administrators,
and assigns, or such others as I, the said John Macintosh, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN ROADS AND WAYS, AND THE MATERIALS USED FOR SUCH PURPOSES," upoń

page_text: the condition (amongst others) that I, the said John Macintosh,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Macintosh, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
The objects of the first part of my Invention are to lessen the expense
of constructing and maintaining roads and ways, and to decrease the
mud, dust, noise, and slipperiness of the same, and this part of the said
Invention consists in covering a concrete or other smooth foundation
with adhesive bitumen or bituminous substance, preferably that known
as natural mastic to render it waterproof, and placing over this bitumen
coarse cloth saturated with vulcanized solution mixed with cotton seed,
pitch, wood, cork, or fibrous waste dust.
In some instances instead of the vulcanized solution I may use the
mastic having incorporated with it this cotton seed, pitch, wood, or
other substance.
The second part of my Invention is designed to lessen the expense of
maintaining macadamised roads, also to diminish the mud, dust, and
noise, and consists in using the mud taken from the roads, the same
being dried, sifted, and rendered impervious to moisture by mixing it
with waterproof materials, such as the aforesaid natural mastic or other
bituminous substance until it becomes a plastic heterogeneous mass, in
which state it can be spread upon the roads.
In some cases it is desirable to smooth and waterproof the road with a
covering of adhesive bitumen alone or in combination with felt before
applying the compound.
It will be readily understood that mud dried and waterproofed which
is inexpensive, durable, preventing the formation of mud and dust is
admirably adapted for covering roads in lieu of broken granite which is
rapidly reduced to mud and dust, necessitating the employment of mon

page_text: and water carts to abate the nuisance, the same being entirely obviated
by my Invention to which I will give the name of the Macintosh
road.
In witness whereof, I, the said John Macintosh, have hereunto set
my hand and seal, this Fourth day of August, in the year of 5
our Lord One thousand eight hundred and seventy-four.
Witness,
H. J. NOONE,
