the Empire of Russia, Gentleman, for the Invention of "AN IMPROVED
SUCKING AND FORCING HYDRO-PNEUMATIC PUMP WITH
P
PROVISIONAL SPECIFICATION left by the said Paul Zaroubine at the
Office of the Commissioners of Patents, with his Petition, on the 29th
June 1867.
I, PAUL ZAROUBINE, of the City of Saint Petersburgh, in the Empire of
Russia, Gentleman, do hereby declare the nature of the said Invention for
"AN IMPROVED SUCKING AND FORCING HYDRO-PNEUMATIC PUMP WITH NO PISTON,"
to be as follows:-
The principle of my new system of pump is the application of the properties of
compressed and rarefied air for the purpose of raising water without the aid of
a piston; the degree of atmospheric pressure or expansion necessary is
arbitrary and does not depend on the variations of height to which it is desired
to raise the liquid, which can be lifted from any depth. The action of the
pump may be either single or double, the double one being merely a combi-
nation of two single-action pumps.
My improved pump is composed of an indefinite number of cylinders placed
one above the other and hermetically united, and communicating one with

page_text: the other by means of pipes, the upper orifices of which are furnished with
valves opening upwards. The cylinders communicate in pairs on each side of
the pump with two pair of bellows by means of two pipes, one on either side
of the apparatus. In working the bellows the action of the pressure and
depression of the atmosphere contained in the cylinders corresponding with
the respective pipes causes the water to leave its primitive level and rise from
one cylinder to the other till it reaches the last or top one, from whence it is
discharged by a pipe into a reservoir or receptacle. A similar pump may be
worked with one pair of bellows communicating with the cylinders in uneven
numbers on condition that the bellows are of greater power than the two
pair combined. In pumps of this description the suction pipe of the uneven
set of cylinders remains open, whilst the cylinders themselves to which this
pipe is in communication are uncovered.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Paul Zaroubine in the Great Seal Patent Office on the 27th
December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
ZAROUBINE, of the City of Saint Petersburgh, in the Empire of Russia,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of June, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Paul Zaroubine, Her special licence that I, the said Paul Zaroubine,
my executors, administrators, and assigns, or such others as I, the said Paul
Zaroubine, 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, SUCKING
AND FORCING HYDRO-PNEUMATIC PUMP WITH NO PISTON," upon the condition
(amongst others) that I, the said Paul Zaroubine, my executors or adminis-
trators, 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Paul Zaroubine, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say:-
The principle of my improved system of pump is the application of the
properties of compressed and rarefied air for the purpose of raising water
without the aid of a piston; the degree of atmospheric pressure or expansion
necessary for the purpose is arbitrary and does not depend on the variations
of height to which it is desired to raise the liquid, which may be lifted from
any depth. The action of the pump may be either single or double, the
double one being merely the combination of two single-action pumps.
Fig. 1 of the accompanying Drawings represents a vertical section of a
single-action pump, and consists of an indefinite number of cylinders a, a, a,
placed one above the other, and herinetically united, and put in communication
one with the other by means of the tubes 1, 1, 1, the upper orifices of which
are furnished with valves b, b, b, opening upwards. The cylinders commu-
nicate in pairs on each side with two pipes e, f, e¹, f¹, which are in connection
with two pair of bellows A, A¹, which are supported in any suitable or con-
venient manner. In working the bellows the action of the pressure and
expansion of the atmosphere contained in the cylinders corresponding with the
respective pipes causes the water to leave its primitive level and to rise from
one cylinder to the other till it reaches the last or top one, from whence it is
discharged by the pipe into a reservoir or other receptacle B. A similar
pump may be worked with a single pair of bellows communicating with the
cylinders in uneven numbers, provided that the bellows are of greater power
than the two A, A¹, combined. In pumps of this description the suction
pipe e, f, of the uneven set of cylinders remains open, whilst the cylinders
themselves, to which this pipe is attached, are closed.
Fig. 2 is a pump of this nature, the cylinders B, B, are shewn open at
the top, whilst the cylinders A, A, are closed. In the tubes 1, 1, 1, the water
rises by suction, and in those 1, 1, 1, by atmospheric pressure; these latter
tubes are furnished at their lower orifices with valves a, a, a.
Fig. 3 represents the exterior of a double-action pump, which in the
Drawing consists of only four cylinders, but the number of which would vary
according to necessity. The pipe l raises the water to the first cylinder, the
pipes,,,, draw it from one cylinder to the other by a continuous action
resulting from the combination of two forces, that of suction and atmospheric

page_text: pressure. All the cylinders, with the exception of that forming the base of the
body, are traversed by suction pipes, the upper orifices of which are in con-
nection with two pair of bellows, which produce the action. By means of
the rings K, K, K, each cylinder is attached to two chains, the length of
which is determined by the depth from which the water has to be raised.
Fig. 4 is a vertical section shewing the interior arrangement of each
cylinder of a double-action pump. The inside of each of the cylinders is
divided into two equal chambers by a vertical division p, q; these chambers
are furnished at the bottom with valves e, f, opening upwards. L is the pipe
communicating with each cylinder. and are ascension pipes having
g and h. Each of the recipients or chambers is traversed by a suction
pipe, 12, placed or curved in such a manner that their upper ends 6 do not
come in contact with the lower orifices c of the pipes a.
valves
One part of the apparatus should be filled with water, leaving the other
empty, that is to say, the apparatus is so arranged and constructed as to be
capable of filling the receivers, whilst at the same time it leaves the tubes free
and empty; thus, after having poured water into the opening a of the upper
tube, the chamber in which this tube is will then fill itself, then when the
level of the water contained in this chamber has reached the opening 6 of the
second suction pipe it empties itself by this opening into the receiver or
reservoir of the second cylinder or element, and so on down to the bottom.
The bellows in connection with the tubes, by aid of which the body of the
apparatus receives the water, remains collapsed before the commencement of
action, its contents being rarefied air, whilst the other bellows is distended and
is filled with compressed air; thus by pressing on the collapsed bellows and
depressing that containing the compressed air the latter exercises a pressure
on the surface of the water contained in all the chambers, since they all con-
municate by means of the suction tubes, and the water finding no other outlet
but the ascension pipes, escapes by these to empty itself in the receiver
containing the rarefied air; for instance, the water will pass from the right-
hand chamber of a lower cylinder to a chamber on the left of the next
cylinder. The bellows acting in an inverse manner the water leaves the left-
hand chambers to fill those of the right, and thus raising itself one cylinder
only at a time. It will thus be observed that the force of ascension results in
the difference of the two forces of compressed and rarefied air.
Fig. 4 represents the moment when the right bellows is inflated and the
left collapsed, that is to say, when the air enclosed in the right chambers
is compressed and that in the left chambers rarefied. The movements of the
water and air corresponding with the moment in question are indicated by the

page_text: different directions of the arrows, the still water being shewn by o, the
compressed air by +, and the rarefied air by
Having thus described my Invention, what I claim and desire to secure by
Letters Patent is, the construction of pumps without pistons, precisely in the
manner and for the purposes herein set forth and illustrated by the accom-
panying Drawings.
In witness whereof, I, the said Paul Zaroubine, have hereunto set my
hand and seal, this Nineteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-seven.
PAUL ZAROUBINE. (L.s.)
