Year: 1865

page_text: LETTERS PATENT to Gaspard Alfred Montenat, of No. 10, Rue de la
Fidélité, Paris, in the Empire of France, Chemist, for the Invention of
Sealed the 6th October 1865, and dated the 12th April 1865.
PROVISIONAL SPECIFICATION left by the said Gaspard Alfred Montenat
at the Office of the Commissioners of Patents, with bis Petition, on
the 12th April 1865.
I, GASPARD ALFRED MONTENAT, of No. 10, Rue de la Fidélité, Paris, in
the Empire of France, do hereby declare the nature of the said Invention for
"A NEW APPARATUS FOR EJECTING AND SPREADING LIQUIDS AND POWDERS," to be
as follows, that is to say:-
This Invention consists in the construction of an apparatus for ejecting
and spreading liquids and powders of all kinds, and the said apparatus can
be fixed permanently on the recipient containing the liquid or powder to be
spread, or it can be made moveable so as to be taken off when required.
The apparatus in its most simple form, and as I chiefly use it for projecting
powders, consists of a conical metallic tube, the larger orifice of which is suffi-
ciently wide to serve as a mouth-piece, and to make it adaptable to a pair
of bellows; the other opening is square. Near to and opposite this orifice is
the end of a second tube or syphon, joined to the first tube by means of a ring
soldered to both tubes at the top of the angle formed by them. The orifice
of the syphon must be large enough to allow the powder to pass out, and can

page_text: be either conical or round, or if the tube has the same diameter throughout,
the orifice should on one side be drawn out to a point, so that the atmosphere
can completely envelope it. The ring joining the two tubes serves also
to connect the apparatus to the recipient of the liquid or powder, either
by means of a piece of india-rubber, or by means of a clip similar to that
employed for fixing the shade of a lamp; it can also be adapted to the recipient
by means of a cylinder traversing the syphon, which is fixed; in this case
a hole made also in the cylinder serves for the admission of the external air.
In the apparatus for spreading liquids the syphon can be lengthened at
will by means of an india-rubber tube placed on the metallic tube.
In the most complicated apparatus the recipient has the form of a cruet
joined to the tube of the bellows by one or more stays; the syphon descends
at the back and turns round into the interior of the recipient or reservoir,
and is soldered on the middle of a tube placed lengthwise on the side of the
bottom of the reservoir. The tube is provided at each extremity with a valve
which opens or shuts according to the position of the apparatus. Externally
the syphon is bent in the shape of an S. The atmospheric pressure acts on
the liquid through a tube so arranged that the apparatus may be inclined in
any direction without the liquid being able to escape. This apparatus can be
adapted to a portable air exhauster, and a spirit lamp can be employed to
heat the liquid, when a warm vapour will be ejected. Applied to a pair of
bellows the apparatus can be employed to disinfect hospitals by ejecting and
spreading in the rooms the liquids usually employed for this purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Gaspard Alfred Montenat in the Great Seal Patent Office
on the 11th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GASPARD
ALFRED MONTENAT, of No. 10, Rue de la Fidélité, Paris, in the Empire of
France, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Gaspard Alfred Montenat, Her special licence that I, the said
Gaspard Alfred Montenat, my executors, administrators, and assigns, or such
others as I, the said Gaspard Alfred Montenat, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time

page_text: 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 "A NEW APPARATUS POR EJECTING AND SPREADING LIQUIDS
AND POWDER," upon the condition (amongst others) that I, the said
Gaspard Alfred Montenat, my executors or administrators, by an instru
ment in writing under my, or their, or one of their bands '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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Gaspard Alfred Montenat, 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, reference being had to the Drawing hereto annexed,
and to the figures and letters marked thereon, that is to say':-
.f
The object of my
Invention consists of improvements in apparatus for
ejecting and spreading all kinds of powders and liquids.
These apparatus are represented in Figures 1, 2, 3, and 4 of the annexed
Drawing, in which the same letters of reference indicate similar parts.
Figure 1 represents a reservoir D, in which is placed across the screw
stopper E' a tube C open at its two ends. 'A small tube G serves for the
atmospheric pressure. By means of a' bellows A, with the mouth or any
suitable mechanical ventilator, air is introduced in the cylindrical or conical
mouth-piece or blowing apparatus B, which is united to the tube C by any
suitable means. The air in passing through the orifice of the tube B meets
the end of the tube C, and draws and ejects the, substance; at the same time
spreading it" from the reservoir D. The tube C can' be composed partly of
metal, partly of caoutchouc, or any other analogous substance. :
(Figure 2 represents another arrangement of the same apparatus; D is a
reservoir opening like a box; B, mouth-piece; F, junction ring of the mouth-
piece with the tube C. This tube C is composed of a part C fixed and
soldered to the box, and with a conical part C soldered to the ring F, and
entering into the part C¹. The ring F is fixed as desired to the reservoir
by means of a right-angled piece soldered to the box, in which it enters. The
reservoir D can be made of cardboard, in which case the blowing apparatus B
can be adapted to the box by means of caoutchouc.
Figure 3 represents the same apparatus simplified, and serving to draw and
eject the above-mentioned substances from any suitable recipient. For this

page_text: purpose I introduce the extremity G of the tube C into the recipient, which
is perforated with holes. The tube C is united to the blowing apparatus B by
means of a ring F. I would remark that I reserve the right of uniting these
two pieces by means of a caoutchouc tube, one of its extremities envelopping
a part of the tube C, and the other a part of the blowing apparatus B. The
part of the caoutchouc tube placed between these parts can be hollowed out.
When liquids are to be ejected a tube C can be employed, formed with a
metallic part and with a part of caoutchouc.
Figure 4 represents the same apparatus arranged for spreading and ejecting
at the same time two of the above-mentioned substances, and is composed of
a reservoir D divided in two by a partition I; in each of the compartments
tubes are plunged, G and G', crossing the screw stoppers E and E¹, across
which the atmospheric tubes also pass, H and H. The tubes G and G¹ are
bent or curved, presenting their openings relative to the orifice of the blowing
apparatus B, by which one can blow by any suitable means. The junction
rings marked F in the three first figures can instead of being soldered directly
to the tubes be soldered to the grooves receiving these tubes. When the
liquids are to be ejected the temperature can be raised by means of a spirit
lamp adapted to the reservoir.
Having now described the nature of my Invention, and the best manner of
putting the same into execution, I declare that I do not restrict myself
to the forms and dimensions of the apparatus above described, nor to the
materials employed in their construction, so long as the principle of my
Invention be retained; but what I claim is, the improved apparatus for
ejecting and spreading powders and liquids, as herein-before described and
represented in the accompanying Drawing.
In witness whereof, I, the said Gaspard Alfred Montenat, have here-
unto set my hand and seal, this Tenth day of October, in the
year of our Lord One thousand eight hundred and sixty-five.
