Year: 1852

page_text: LETTERS PATENT to Auguste Baboneau, Manufacturer, of Paris,
in the French Republic, for the Invention of "AN IMPROVED
APPARATUS FOR MELTING AND MIXING ASPHALT WITH BITUMEN AND
OTHER SUBSTANCES.
Sealed the 10th May 1853, and dated the 10th November 1852.
PROVISIONAL SPECIFICATION left by the said Auguste Baboneau
at the Office of the Commissioners of Patents, with his Petition,
on the 10th November 1852.
I, AUGUSTE BABONEAU, Manufacturer, of Paris, in the French
Republic, do hereby declare the nature of the said Invention for
"AN IMPROVED APPARATUS POR MELTING AND MIXING ASPHALT WITH
BITUMEN AND OTHER SUBSTANCES" to be as follows:-
My apparatus consists of a furnace, over which is placed an iron
vessel, into which the asphalt to be melted, and the materials to
be mixed with it, are inserted through a hole, which can be closed
by means of an iron door. The materials are mixed by means of a
stirrer, which is put in motion from the enterior by means of a

page_text: handle or other means. The vapour arising from the melted asphalt
is carried by means of a tube to the chimney of the furnace in such
a manner that the vapours become condensed and remain in the
tube. The whole apparatus is placed on wheels, so that it can be
taken to any place where the asphalt may be required.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Auguste Baboneau in the Great Seal
Patent Office on the 10th May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
AUGUSTE BABONEAU, Manufacturer, of Paris, in the French Republic,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of November,
in the year of our Lord One thousand eight hundred and fifty-two,
in the sixteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Auguste Baboncau, Her
special licence that I, the said Auguste Baboncau, my executors,
administrators, and assigns, or such others as I, the said Auguste
Baboneau, my executors, adininistrators, 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 "AN IMPROVED APPARATUS FOR MELTING AND MIXING
ASPHALT WITH BITUMEN AND OTHER SUBSTANCES," upon the condition
(ainongst others) that I, the said Auguste Baboneau, by an
instrument in writing under any hand and seal, should particu-
larly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the saine to
be filed in the Great Seal Patent Office within six calendar inonths
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Auguste Baboncau, do hereby

page_text: declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
My apparatus consists of a furnace, over which is placed an iron
vessel into which the asphalt to be melted and the materials to be
mixed with it are inserted, through a hole which can be closed by
means of an iron door. The materials are mixed by means of a
stirrer, which is put in motion from the exterior by means of a
handle or other means. The vapour arising from the melted asphalt
is carried by means of a tube to the chimney of the furnace, in such
a manner that the vapours become condensed and remain in the
tube. The whole apparatus is placed on wheels, so that it can be
taken to any place where the asphalt maybe required.
And in order that the Invention may be more fully understood,
I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1, a side elevation of the machine, partly in section.
Figure 2, is an end view. Figure 3, is the other end view; and
Figure 4, is a transverse section. In each of these figures the same
letters of reference indicate the same parts. a, a, is an iron-vessel
into which the asphalt and material are put; b, b, are covers
opening on hinges; c, c, is the exterior casing; d, d, is the fire
place; e, e, flues along which the heat and products of combustion
pass, before passing into the central flue f, from which they pass
into the chimney f¹. The materials are kept agitated by the
stirrer 1,, on the axis A, which is put in motion by the handle n,
which gives motion to the pinion o, and thence to the spur wheel p,
on the axis, which turns in bearings m, m. The products evolved
from the asphalt and other matters pass up the pipe g, where some
of the products are condensed in g', from which they may be drawn
off, through a hole at g², by a syphon, which hole at other times is
kept closed; i, i, are wheels on which the machine is moved from
place to place.
Having thus described the nature of my said Invention, and the

page_text: manner of performing the same, I would have it understood that I
make no claim to any of the parts separately, nor do I confine
myself to the details shown; but what I claim is, the combination
of apparatus or parts herein described.
In witness whereof, I, the said Auguste Baboncau, have
hereunto set my hand and seal, this Seventh day of May,
in the year of our Lord One thousand eight hundred and
fifty-three
