AN IMPROVED FUMIGATING APPARATUS
Year: 1858

page_text: LETTERS PATENT to Marc Antoine François Mennons, of the British and
Foreign Patent Offices, 39, Rue de l'Echiquier, Paris, in the Empire of
France, for the Invention of "AN IMPROVED FUMIGATING APPARATUS."
A communication.
Sealed the 25th November 1858, and dated the 29th May 1858.
PROVISIONAL SPECIFICATION left by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition, on the 29th May 1858.
I, MARC ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent
Offices, 39, Rue de l'Echiquier, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "AN IMPROVED FUMIGATING
APPARATUS," a communication, to be as follows:-
This apparatus is composed of a recipient in glass, porcelain, or metal, fitted
with a moveable head, which is mounted with tubes drawn to a point. The
recipient being charged with the substance to be volatilised, is heated by
means of a spirit lamp, and the gases produced in egressing from the moveable
head-piece cause the latter to revolve, and disseminate the vapour into the
apartment. It is evident that the same result may be obtained by mounting
the recipient itself so that it may rotate freely on its axis.

by the said Marc Antoine François Mennons in the Great Seal Patent
Office on the 26th November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices,
39, Rue de l'Echiquier, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of May, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Marc Antoine François Mennons, Her special licence that I, the said
Marc Antoine François Mennons, my executors, administrators, and assigns,
or such others as I, the said Marc Antoine François Mennons, 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 "AN IMPROVED FUMIGATING APPARATUS," (a com-
munication,) upon the condition (amongst others) that I, the said Marc Antoine
François Mennons, 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 Marc Antoine François Mennons, do
hereby 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, reference being had to the Figures of the accom-
panying Drawing, and to the letters marked thereon, that is to say:-
The Invention communicated to me is based on an application of the
reacting steam turbine principle to the construction of an apparatus for
separating and distributing the volatile constituents of various perfumes and
pharmaceutical products.
Figures 1, 2, 3, 4, of the accompanying Drawing, represent primary forms
of the apparatus, with fixed recipient and moveable turbine.
Figure 5 represents a modification of the above, in which the recipient and
turbine rotate together.

Fig. 5 represents a modification of the apparatus, in which the recipient and
turbine follow the same movement of rotation. A, pedestal; B, lamp;
C, vertical support of the centre point, on which revolves the recipient; D;'
revolving recipient, forming part of the turbine; E, fixed turbine; F, centre
point, on which the apparatus revolves; G, collar, in which revolves the neck
of the recipient.
The recipient being charged with the substance to be volatilised, and the
lamp lighted, the vapour disengaged by the orifices of the turbine produce a
movement of rotation, the speed of which is proportioned to the elastic force of
the gases evolved, and the diameter of the escape apertures. It is evident
that the dispersing or distributing power of the revolving jets is far superior
to that of a simple evaporating surface of considerable extent. To this fact is
due much of the utility of the apparatus when employed for the volatilisation
of perfumes, antiseptics, and medicinal compounds of a certain value, the
maximum effect being obtained at the most economical rate possible. When
intended for use in purifying the vitiated air of hospitals, lazarettoes, dissecting
rooms, barracks, and other establishments exposed to deleterious emanations,
the dimensions of the apparatus should be proportioned to the extent of the
building or locality to be acted on. For perfuming or disinfecting ordinary
appartments, the dimensions given in the Drawing are amply sufficient.
The following perfumes and medical compounds may be noted among
those advantageously employed with this apparatus:-Alcoholic and other
solutions or extracts of aromatic plants and resins, such as rose and lavender
waters, tinctures of mint, myrrh, and verbena, cau de cologne, and toilet
vinegars, empyreumatic and essentials oils, benzoin, balsams of Tolu, Peru,
etc., etc., etc.
For hospital, barrack, or prison use, a supply of chlorine may be readily
obtained by the decomposition of chloride of lime, muriatic acid with oxide of
manganese, or other substances having chlorine for base.

page_text: Having thus described the nature of the said Invention, and the manner
of carrying it into effect, I would have it understood that I do not limit
myself to the forms, dimensions, or general details above laid down, as these
may be varied to almost any extent without departing from the principle of
the Invention, which reposes on the application of the reacting steam turbine
to the construction of a fumigating apparatus, substantially as above described,
and represented in the Figures of the annexed Drawing.
In witness whercof, I, the said Marc Antoine François Mennons, have
hereunto set my hand and seal, this Twenty-fifth day of Novembre, in
the year of our Lord One thousand eight hundred and fifty-eight.
M. F. MENNONS. (L.s.)
