PROVISIONAL SPECIFICATION left by the said Charles Jean le Melorel
de la laichois at the Office of the Commissioners of Patents. with his
Petition, on the 31st March 1856.
1, CHARLES JEAN LE MELOREL DE LA HAICHOIS, of 39, Rue de l'Echiquier,
Paris, and of 4, South Street, Finsbury, London, Advocate, do hereby declare
the nature of my said Invention for "CERTAIN IMPROVEMENTS IN PAVING," to be
as follows, that is to say:-
These improvements consist, first, in an application on the part to be paved
of a (beton) composition of lime and sand to the thickness of about six inches.
Second. in a second application of asphalte mixed with stone to the thick-
ness of about two inches.
Third, in a third application of asphalte, pure, or mixed with sand to the
depth of about one inch, in which squares or sheets of vulcanized caoutchouc
or gutta percha are embedded ai equal distances. In this third application, a
layer of asphalte of about half an inch in depth is first laid down, and after-
wards small squares of vulcanized caoutchouc or gutta percha, of about half

page_text: an inch in thickness, and half to three-quarters of an inch in breadth placed
on it. These squares are placed at six to ten inches apart, and are provided
with iron hooks or ties, at distances of from six to ten inches, which pass
through them from side to side. A second bed of asphalte, pure, or mixed
with sand, is then laid down to the depth of about half an inch. so as to cover
the iron hooks or ties, and conie up to the level of the squares of caoutchouc
or gutta percha. The third application may be made by first laying down a
coating of asphalte mixed with stone, with small wooden cross pieces, of one to
two inches in breadth and about one inch in thickness, and placing on them
the squares of caoutchouc or gutta percha prepared as above described. In
this case the application of asphalte to the thickness of one inch may be
effected at one operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Jean le Melorel de la Haichois. in the Great Seal
Paient Office on the 26th September 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I. CHARLES
JEAN LE MELOREL DE LA HAICHOIS, of 39, Rue de FEchiquier. Paris, and 4,

WHEREAS Her most Excellent Majesty Queen Victòria. by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did for Herself. Her heirs and successors, give and grant unto me, the said
Charles Jean le Melorel de la Haichois, Her special license that I, the
said Charles Jean le Melorel de la Haichois, my executors. administrators,
and assigns, or such others as I, the said Charles Jean le Melorel de la
Haichois, 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 CERTAIN IMPROVE-
MENTS IN PAVING, upon the condition (amongst others) that 1, the said Charles
Jean le Melorel de la Haichois, by an instrument in writing under my hand
and seal. should particularly describe and ascertain the nature of the said In-
vention, 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,

page_text: NOW KNOW YE, that I, the said Charles Jean le Melorel de la
Haichois, do hereby declare the nature of my said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, that is to say:
These improvements consist in the employment of lime, sand, asphalte,
caoutchouc, gutta percha, and marine glue, and wood. for the purpose of
forming an even and durable pavement, which substances are applied in the
following manner:-
A layer composed of line and sand (beton) is laid down to the thickness of
about five inches on the part to be paved, then a layer of asphalte mixed with
stones to the thickness of about two inches is applied, after which a layer of
asphalte, either alone or mixed with sand to the depth of about one inch, is
laid down, in which are embedded at certain equal distances strips or bands of
vulcanized caoutchouc or gutta percha.
In the last application, a layer of asphalte of about half an inch in depth is
first laid down, and afterwards the strips or bands of vulcanized caoutchouc or
guita percha, or other analogous substances, of about half an inch in thickness.
and from a half to three-quarters of an inch in breadth, so as to form squares
or lozenges. The strips are placed from six to ten inches apart, and are
secured together by iron hooks or ties, at a distance of three to five inches
from each other, which hooks pass through them. Instead of using hooks, the
sirips may be bevelled at the edges, so as to be firmly embedded in and secured
by the asphalte. When the strips are laid down, a second layer of asphalte is
applied, so as to be on a level with the strips of caoutchouc.
The paving may be constructed by first laying down on a bed or layer of
asphalte, mixed with small stones, small cross pieces of wood (of about one to
iwo inches in breadth and half an inch in thickness). injected, according to
Dr Boucheries process. Upon these cross pieces are placed the strips or
bands of vulcanized india-rubber or gutta percha, prepared as herein-before
described.
As asphalte does not naturally adhere to caoutchouc, it is necessary to apply
a thin coat of marine glue or other similar substance to those parts to be
placed in contact with the asphalte before being laid down: the asphalte being
hot will cause the marine glue to melt and adhere to it strongly.
The strips
of caoutchouc should be embedded in and secured to the asphalte during the
cooling of the latter.
Having now described the nature of my said Invention. and the manner in
which the same may be carried into effect. I would observe that I do not
confine myself to the precise details herein laid down, reserving to myself the

page_text: right of modifying the same; int what I claim is, the method of constructing
pavement in the manner herein-before described.
In witness whereof, I. the said Charles Jean le Melorel de la Haichois.
have hereunto set my hand and seal, this Twenty-third day of
September, in the year of our Lord One thousand eight hundred and
fifty-six.
Witness,
M. F. MENNONS.
