page_text: LETTERS PATENT to Abraham Abrahams, of Saint Peter's Park, in
the County of Middlesex, for the Invention of "AN IMPROVED
MODE OF AND APPARATUS FOR PRODUCING THE EVAPORATION OF PERFUMING
AND OTHER FLUIDS."
Sealed the 14th July 1874, and dated the 17th January 1874.
PROVISIONAL SPECIFICATION left by the said Abraham Abrahams.
at the Office of the Commissioners of Patents, with his Petition,
on the 17th January 1874.
I, ABRAHAM ABRAHAMS, of Saint Peter's Park, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"AN IMPROVED MODE OF AND APPARATUS FOR PRODUCING THE EVAPORATION OF
PERFUMING AND OTHER FLUIDS," to be as follows:-
According to this Invention the fluid to be evaporated, be it eau-de-
Cologne or other perfume, or be it camphor or other disinfectant, is
distilled with or dissolved in alcohol or other liquid containing hydrogen,

page_text: and the mixture is placed in a glass or other vessel, where it is submitted
to the action of a platinum burner suspended above the liquid. This
burner is a simple disc of platinum. It is suspended from a wire carried
up from a cork or other float on the surface of the liquid in the vessel.
The vessel is held in a suitable stand, and is provided with a cover in
which are one or more apertures, which can be entirely or partially closed
as required by means of a slide or shutter.
To use the apparatus apply a flame to the alcoholic liquid in the
vessel, and in a very short time the platinum will become red hot. Then
close the cover so as to cause the flame to become extinguished, and
then again open the apertures in the cover, so as to admit enough
atmospheric air to keep up the combustion. The hydrogen evolved
from the alcohol becomes condensed upon the platinum combines with
the oxygen of the air, and forms water which evaporates immediately,
while the intensity of the combination of the oxygen and bydrogen is
sufficient to keep the platinum at a red heat.
The perfume or disinfectant in the liquid being volatilized escapes
into the room.
When the vessel containing the liquid is made of glass the red-hot
platinum (the brightness of which is continually varying) can be seen,
so that the apparatus, in addition to being an economical perfumer or
deodorizer, presents a pleasing appearance, more particularly if the

page_text: the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Abraham Abrahams, Her
special licence that I, the said Abraham Abrahams, my executors,
administrators, and assigns, or such others as I, the said Abraham
Abrahams, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 MODE OF AND APPARATUS FOR PRODUCING THE EVAPORATION OF
PERFUMING AND OTHER FLUIDS," upon the condition (amongst others) that
I, the said Abraham Abrahams, 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 Abraham Abrahams, 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 thereof, reference being had to the
accompanying Drawings, that is to say :-
According to this Invention the fluid to be evaporated, be it eau-de-
Cologne or other perfume, or be it camphor or other disinfectant, is
distilled with or dissolved in alcohol or other liquid containing hydrogen,
and the mixture is placed in a glass or other vessel, where it is submitted
to the action of a platinum burner suspended above the liquid. This
burner is a simple disc of platinum. It is suspended from a wire carried
up from a cork or other float on the surface of the liquid in the vessel.
The vessel is held in a suitable stand, and is provided with a cover in
which are one or more apertures, which can be entirely or partially
closed as required by means of a slide or shutter.
To use the apparatus apply a flame to the alcoholic liquid in the
vessel, and in a very short time the platinum will become red hot. Then
close the cover so as to cause the flame to become extinguished, and

page_text: then again open the apertures in the cover, so as to admit enough
atmospheric air to keep up the combustion. The hydrogen evolved
from the alcohol becomes condensed upon the platinum, combines
with the oxygen of the air, and forms water which evaporates imme-
diately, while the intensity of the combination of the oxygen and a
hydrogen is sufficient to keep the platinum at a red heat.

perfuming and other fluids by means of platinum; and more particularly
I claim the combination of the float I, wire K, and platinum M, in the
manner described and shewn.
In witness whereof, I, the said Abraham Abrahams, have here-
unto set my hand and seal, this Sixteenth day of July, One
thousand eight hundred and seventy-four.
