limited and imperfect application has till now been made. This
rolling is accomplished by means of rollers appropriate for the
purpose, such as those used for rolling out lead, &c. The Drawing
of the design for a roller, which is proposed for rolling bitumen

are then placed in metal cauldrons. When the mass has arrived at
a suitable degree of fusion, it is passed through a sieve placed
above the cylinders of the rollers, between which it passes, and
which are regulated to the thickness required to give the sheets.
These cylinders are put in motion either by hand or by any other
power. On the right and left of these cylinders are placed, at a
suitable height & distance on each side of the sieve, winding off
rollers, around which are rolled either paper continuous, or canvas,
or any kind of cloth, or even a metallic fabric, in order to facilitate
the rolling, or to give the rolled sheets a greater solidity and more
uniform surface. In certain cases, an intermediate sheet is added
by means of a third winding off roller and directing rods. This
third sheet then passes into a case, which divides the sieve into two
parts, & thus becomes placed in the middle of the rolled mass, which
thus preserves it from all wear and decomposition. This sheet serves
as a foundation to the laminated matter, and adds to its solidity. The
cloth or paper may be dispensed with. In such case, care must be
taken to powder or wet the cylinders to prevent adherence of the
mass. The mass is rolled in all required thicknesses, according to
the application for which it is desired. When it is wished that the
rolled sheets should have greater density, they are rolled repeatedly,
or caused to pass through a series of successive cylinders set closer
and closer. In certain cases, many rolled sheets may be joined
together, and be laminated again. Sheets of bitumen & asphalte
can be laminated of all sizes, according to the size of the rolling
cylinders, & of any length. They may be then cut to the requisite

one on another.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Auguste Edouard Loradoux Bell
ford in the Great Seal Patent Office on the 8th August 1853.
TO ALL TO WHOM THESE PRESENTS
THESE PRESENTS SHALL COME, I,
AUGUSTE EDOUARD LORADOUX BELLFORD, of 16, Castle Street,
Holborn, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of February, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Auguste Edouard Loradoux
Bellford, Her special licence that 1, the said Auguste Edouard
Loradoux Bellford, my executors, administrators, and assigns, or
such others as I, the said Auguste Edouard Loradoux Bellford,
ny 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, communicated to me by a foreigner residing abroad, for
"IMPROVEMENTS IN THE TREATMENT OF BITUMINOUS AND ASPHALTIC
MATTERS, RENDERING THEM APPLICABLE TO VARIOUS USEFUL PURPOSES,"
upon the condition (amongst others) that I, the said Auguste
Edouard Loradoux Bellford, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in which 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 1, the said Auguste Edouard Loradoux
Bellford, 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 (that
is to say):
This Invention consists specially in the rolling of bituminous
and asphaltic matters of all kinds; that is to say, in a new manner
of treating them, and consequently of applying them to new pur-
poses, and to which they have not hitherto been applied, or to which
a very limited and imperfect application has till now been made.
This rolling is accomplished by means of rollers appropriate for the
The
purpose, such as those used for rolling out lead, &c. &c.
Drawing of a roller proposed for rolling bitumen and asphalte
is annexed hereunto. To work the rolling of the asphalte and
bitumen of all kinds, they must first be prepared by purifying and
mixing or amalgamating them according to the proportions neces-
sary for their different applications. They are placed then in
metal cauldrons. When the mass has arrived at a suitable degree
of fusion, it is passed through a sieve placed above the cylinders of
the rollers between which it passes, and which are regulated to the
thickness required to give the sheets. These cylinders are put in
motion either by hand or by any other power. On the right and
left of these cylinders are placed, at a suitable height and distance
on each side of the sieve, winding off or dividing rollers, around
which are rolled either continuous paper, or canvas, or any kind of
cloth, or even a metallic fabric, in order to facilitate the rolling, and
to give the rolled sheets a greater solidity and more uniform surface.
In certain cases, an intermediate sheet is added by means of a third
winding off or dividing roller and directing rods. This third sheet
then passes into a case, which divides the sieve into two parts, and
thus becomes placed in the middle of the rolled mass, which thus
preserves it from all wear and decomposition. This sheet serves as
foundation to the laminated matter, and adds to its solidity. The
cloth or paper may be dispensed with. In such case, care must be
taken to powder or wet the cylinders to prevent adherence to the

closer.
When it is wished that the
rolled sheets should have greater density, they are rolled repeatedly,
or caused to pass through a series of successive cylinders set closer and
In certain cases many rolled sheets may be joined together and
be again laminated. Sheets of bitumen and asphalte can be laminated
of all sizes, according to the size of the rolling cylinders, and of any
length. They may be then cut to the requisite length for use with
shears, as for sheet iron, lead, or zinc. The. welding of the sheets to-
gether is effected by the application of heat, as for lead or zinc; or cold,
with a kind of glue, composed of resin, oil, tar, and asphalte in powder,
or even by compressing the edges one on another.
It is proposed
to employ bituminous and asphaltic matters laminated for the fol-
lowing purposes:-Coverings of all kinds of buildings, sheds, &c.,
supplying the place of tiles, slates, lead, zinc, copper, sheet iron,
thatch, &c.; terraces and walks, in place of lead, &c.; gutters for
water; pipes for rain or water, and drain pipes; coatings for walls,
partitions, and for filling up spaces in partitions, instead of plaster,
mortar, &c.; to preserve dwellings from dampness, in place of
sheets of lead, cement, or painting impervious to water; pave-
ments and floorings for dining rooms, baths, washing stands, wash-
houses, cellars, and other damp places; coverings of copings of
walls in place of tiles, slates, zinc, lead, and mortar, facings of
bridges, arches, &c. in place of lime & cement; footways on wooden
bridges; lining of tubs, reservoirs, &c.; sheathing of vessels by
means of metallic sheets, joined with copper; coffins and tombs in
place of lead; covering of packages for transport by sea.
In witness whereof, I, the said Auguste Edouard Loradoux
Bellford, have hereunto set my hand and seal, this Fifth day
of August, in the year of our Lord One thousand eight
hundred and fifty-three.
