PROVISIONAL SPECIFICATION left by the said Edmond Armand Louis
D'Argy at the Office of the Commissioners of Patents, with his Petition,
on the 15th March 1858.
I, EDMOND ARMAND LOUIS D'ARGY, of Batignolles, near Paris, in the
Empire of France, Manufacturer, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED ROTARY HYDRAULIC BLOWING ENGINE," to.
be as follows:-
My Invention relates to a rotatory bydraulic blowing machine capable of
being employed for both minor and important industrial purposes, it is
applicable both as a blowing and an exhausting machine.
It is represented in the Drawings hereunto annexed, in which Fig.. 1
represents a side elevation of the apparatus, and in which the cistern is shown
in section; Fig. 2, an end view of the same apparatus, also with the cistern in.
section; Fig. 3, a separate view of the nave or centre of the blowing machine:
on a scale of double size. In all these three Figures similar letters of reference
indicate like parts where they recur. a, wooden or metal cistern or reservoir,.

page_text: it is nearly filled with water; b, first metal tube, it is of a spiral or bent form
and forms one arm of the machine; c, second metal tube of a similar form, i
is the second arm of the machine; d, third metal tube like the two former
and which forms the third arm of the machine. These three tubes are united
so as to divide the circumference into three equal parts, and so that the one
extremity attached to the nave is on the same radius as the other extremity at
the circumference; e, cylindrical nave or centre of sufficient capacity, the air
and water introduced into the tubes at each revolution enter this nave; f, first
partition placed in the interior of nave e, between tubes 6 and c; g, second
partition also placed in nave e, between tubes c and d; h, third partition
placed like the two former in nave e, between tubes d and b. These par-
titions are used to prevent the water coming through one of the tubes,
impeding the passage of the air forced through the two others; i, box of
sufficient capacity, made of wood or metal; the water after passing into nave e
enters this box, it descends to the bottom of the cistern or reservoir a;
j, j, partitions extending nearly throughout the length of the box i; they are
intended to cause the water coming from the tubes to descend to the lower
part of box i, and also that the air may not escape at the same time as the
water; k, k, conduits formed by partitions j,j, and by the sides of the box i;
they cause the water to ascend to the upper part of cistern a; 1, 1, sluices
placed at the upper part of conduits k, k, serving to throw the water in box i
back into reservoir a; m, tube forming the air discharge passage, it is placed
for this purpose at the upper part of box i; n, shaft of the apparatus, it is
affixed to each extremity of nave e, and traverses box i without friction;
o, o, bearings of shaft n; they are fixed to the upper part of reservoir a, one on
each side of the rotating tubes; p, p, crank handles fixed to each extremity of
shaft n, if the machine is a small apparatus which can be actuated by hand;
in the case of larger apparatus the crank handles are replaced by pullies
receiving their rotary motion from suitable power.
The action of this apparatus will be easily understood. Supposing all the a
parts mounted as indicated in the Drawings, the reservoir a full of water, and
shaft n having rotary motion in the direction of the arrow's flight imparted to
it, the following takes place:-At the moment the action commences the
machine is entirely filled with air by the rotary motion, and at the moment
when the extreme orifice of one of the tubes b, for example, meets the level of 3
the water, this water will drive the air contained therein to the interior, and.
this air not finding any other outlet passes through the nave e, then through
box i, and will pass out thence. through tube m, the water. following the
same course will reach box i, and then owing to its weight will descend.

page_text: and occupy the lower part of this box i, and being followed by another
quantity of water arriving, it réascends into conduits k, k, and returns into
réservoir a by means of the sluices 1, l. The same will take place during the
rotation of the machine at each time the extremity of either of the tubes
enters the water in the reservoir. Hence it will be seen that the quantity of
air which will be forced through this machine depends entirely on the capacity
of the tubes, and the speed of the rotation imparted to the apparatus. It
will also be seen that with this arrangement there can be no escape water,
forming a perfect closure and preventing any escape.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmond Armand Louis D'Argy in the Great Seal Patent
Office on the 14th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMOND
ARMAND LOUIS D'ARGY, of Batignolles, near Paris, in the Empire of France,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Fifteenth day of March, 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 Edmond Armand Louis D'Argy, Her special licence that I, the
said Edmond Armand Louis D'Argy, my executors, administrators, and
assigns; or such others as I, the said Edmond Armand Louis D'Argy, 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 "A NEW OR IMPROVED ROTARY
HYDRAULIC BLOWING ENGINE," upon the condition (amongst others) that I,
the said Edmond Armand Louis D'Argy, 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 Edmond Armand Louis D'Argy, do
hereby declare the nature of my said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Sheet of Drawings
hereunto annexed, and to the letters and figures marked thereon, that is
to say :-
My Invention relates to a rotary hydraulic blowing machine, capable of
being employed for both minor and important industrial purposes; it is appli-
cable both as a blowing and an exhausting machine. It is represented in the
Drawings hereunto annexed, in which Figure 1 represents a side elevation of
the apparatus, and in which the cistern is shown in section; Fig. 2, an end
view of the same apparatus, also with the cistern in section; Fig. 3, separate
view of the nave or centre of the blowing machine on a scale of double size.
In all these Figures similar letters of reference indicate like parts where they
recur. a, wooden or metal cistern or reservoir, it is nearly filled with water;
b, first metal tube, it is of a spiral or bent form, and forms one arm of the
machine; c, second metal tube of a similar form, it is the second arm of
the machine; d, third metal tube like the two former, it forms the third arm
of the machine. These three tubes are united, so as to divide the circum-
ference into three equal parts, and so that the one extremity attached to the
nave is on the same radius as the other extremity at the circumference;
e, cylindrical nave or centre of sufficient capacity, the air and water introduced
into the tubes at each revolution enter this nave; f, first partition placed in
the interior of nave e between tubes b and c; g, second partition, also placed
in nave e between tubes c and d; h, third partition, placed like the two former
in nave e between tubes d and b. These partitions are used to prevent the
water coming through one of the tubes impeding the passage of the air forced
through the two others; i, chamber of sufficient capacity, made of wood or
metal; the water after passing into nave e enters this chamber and descends to
the bottom of the cistern or reservoir a; j,j, partitions extending nearly
throughout the length of chamber i; they are intended to cause the water
coming from the tubes to descend to the lower part of chamber i, and also
that the air may not escape at the same time as the water; K, K, conduits
formed by partitions j, j, and by the sides of the chamber i; these cause the
water so discharged to ascend to the upper part of cistern a; 1, 1, sluices or
channels placed at the upper part of conduits K, K, serving to throw the water
in chamber i back into reservoir a; m, tube forming the air discharge passage,
it is placed for this purpose at the upper part of chamber i; n, shaft of the
apparatus, it is affixed to each extremity of nave e, and traverses chamber i
without friction; o, o, bearings of shaft n, they are fixed to the upper part
of reservoir a, one on each side of the rotating pipes; p, p, crank handles

page_text: fixed to each extremity of the shaft if the machine is a small apparatus which
can be actuated by hand, in the case of larger apparatus the crank handles
are replaced by pullies receiving their rotary motion from suitable power.
The action of this apparatus will be easily understood. Supposing all the
parts mounted, as indicated in the Drawings, the reservoir a full of water and
shaft n having rotary motion in the direction of the arrow's flight imparted to
it, the following takes place:-At the moment the action commences the
machine is entirely filled with air by the rotary motion, and at the moment
when the extreme orifice of one of the tubes b, for example, meets the level
of the water, this water will drive the air contained therein to the interior,
and this air not finding any other outlet passes through the nave e, then
through chamber i, and passes thence through tube m, the water following the
same course will reach chamber i, but then owing to its weight it will
descend and occupy the lower part of this chamber, and being followed by
another quantity of water arriving, it reascends in conduits K, K, and returns
into reservoir a by means of the channels or sluices l, l. The same will take
place during the rotation of the machine at each time the extremity of either
of the tubes enter in the water in the reservoir. Hence it will be seen that
the quantity of air which will be forced through this machine depends entirely
on the capacity of the tubes and the speed of the rotation imparted to the
apparatus. It will also be seen that with this arrangement there can be no
escape, water forming a perfect closure, and preventing any escape taking place.
The advantages of this apparatus are the following:
:-
1st. As to the duration of the apparatus; it being all of metal and without
valves of any kind, it cannot become deranged, and the tear and wear is of
the most trifling kind, the water playing the part of valves in producing
all the different effects.
2ndly. As to construction; this apparatus has another remarkable advantage,
since there will be about two-thirds saving in the net cost, especially for
blowing machines used for melting metals or other metallurgic operations on
a large scale.
3rdly. In the motive power necessary for driving this machine there will
be a saving of about two-thirds, especially if considered with reference to
blast cylinders, the useful effect will be from 60 to 70 per cent., the ordinary
rotary blowing machine and ventilator giving but 20 per cent.
4tbly. For small metallurgical operations (forges, for instance,) this appa-
ratus could be substituted for the ordinary apparatus with immense advantage,
which ordinary apparatus is attended with great inconvenience, being inter-

page_text: mittent in its working and action, and causing great fatigue to the workman,
especially when heating the iron to a white heat.
5thly. For a movement of rotation it certainly offers more convenience and
facility than a reciprocating movement, considered either with reference to the
application of manual labour (being more uniform in its motion), or as a large
blowing machine intended to be worked by other power; it suffices in this
last case to apply a simple leather strap applied to a pulley, with which it
produces its effect instantly and directly. It is very evident that by reason of
all these advantages over existing blowing machines this apparatus will
become generally adopted in all manufactures or working of metals, as much
for the economy as for the simplicity and the perfection of its working. Inde-
pendent of all these incontestable advantages, I yet see other applications to
its working in jewellery and other gold and silversmith's work; for example, it
will be an excellent propeller of gas for soldering by the blowpipe; by decom-
posing water it may be worked by the two gases which that element contains.
I believe also that it is applicable as apparatus in the combustion of smoke
for ventilation, and for exhausting.
Having described the nature of my Invention and the manner of performing
the same,, I declare that what I claim as my Invention to be secured by the
herein-before in part recited Letters Patent is, the rotary blowing machine
herein-before described, composed of three or of other greater number of bent
tubes or channels arranged in a circle and turning in a bath of water, these
tubes taking in by their open extremities the air or gas and the water in the
bath, and impelling all towards the centre or nave, the water returning to the
bath or vessel while the air is forced towards the fire or used for any other
purpose. These several tubes being equally divided on the circumference
have the effect of producing a constant pressure and blast of air or gas.
In witness whereof, I, the said Edmond' Armand Louis D'Argy, have
hereunto set my hand and seal, this Eleventh day of September, in
the year of our Lord One thousand eight hundred and fifty-eight.
