"IMPROVEMENTS IN APPARATUS FOR LIFTING AND FORCING WATER AND OTHER
FLUIDS." [A communication from abroad by Christian Frederick Budenberg, of
the Firm of Schäffer and Budenberg, of Buckau, Magdeburg, Germany.]
These improvements relate to apparatus used for lifting and forcing water and
other fluids by the direct action of steam, and consist in providing an injection of
water or other fluid for the purpose of condensing the steam in such a manner that
the quantity of water or other fluid so injected is in proportion to the amount of
water or other fluid delivered by tlie apparatus, and in the arrangement and action
of the valves. The apparatus which is constructed upon the same general principle
as the well known "steam pressure lift pump," is provided with two or more
barrels or chambers having each a suction valve at its lower end. These barrels or
chambers may be tapered towards the top, or be otherwise formed, so that orifices
which are there provided for the inlet of steam may be conveniently near to each
other, and be included within a steam chamber common to them both, or all, if
there are more than two barrels or chambers. The orifices hereinbefore mentioned
are capable of being closed or opened by means of a valve or valves mounted on a
point, pivot, axis, or knife edge, in such a manner that it may have communicated
to it a rocking motion, so that when one part of the valve is depressed and closes
the orifice leading into one of the barrels or chambers, the opposite part of the valve
is raised, and opens the orifice leading into the adjoining barrel or chamber, it
being thus possible to have only one barrel or chamber out of each pair open to the
steam space at any given time.
The barrels or chambers are in communication with each other by means of
curved pipes;
each of these pipes has its opening pointed downwards in one of the
barrels or chambers, and thence passes into the adjoining barrel or chamber where

page_text: its opening is directed upwards; the lower opening may be placed near to the
suction valve, and the upper opening in the adjoining barrel or chamber is carried
to a convenient height, and is provided with a back pressure valve.
At or near the bottom of each barrel or chamber is a port opening into a delivery
chamber, which in its turn opens into a branch of the delivery pipe, the foot of the
branch of the delivery pipe being provided with a back pressure valve to prevent
the return of the water or other fluid to the apparatus. A vent or air valve may
also be inserted at or near the top of each barrel or chamber.
From the foregoing it will be seen that steam can pass into only one barrel or
chamber out of each pair at the same time. The steam so entering forces the
water contained in the barrel or chamber through the port into the delivery
chamber hereinbefore described, and thence into the delivery pipe; the steam then
reaching the port and delivery chamber encounters suddenly a large increase in the
surface of the water or other fluid, and a correspondingly sudden reduction of
pressure which causes the valve to close, and thus stops the further admission of
steam, the same action raising the opposite portion of the valve, and giving
admission of steam to the adjoining barrel or chamber. The further entrance of
steam having been prevented, as herein before described, the then existing excess of
pressure in the adjoining barrel or chamber drives a portion of the water or other
fluid contained therein through the curved pipe already described into the barrel
or chamber in which the condensation is going on. The back pressure or check
valves on the upper openings of the curved pipes permit the injection of water or
other fluid into that barrel or chamber only in which condensation is taking place,
and during the period of condensation only.
By this condensation a vacuum or partial vacuum is produced, and as a well
known result the water or other fluid flows into the barrel or chamber. These
operations are repeated alternately in each chamber or barrel as in the case of the
"steam pressure lift pump," and other well known and similar apparatus, with this
difference, that the condensation of the steam by means of the injection of
water or other fluid considerably hastens the operation, and thereby increases the
number of "beats" and the quantity of water or other fluid delivered in a given
time.

the said Arnold Budenberg in the Great Seal Patent Office on the 2nd
August 1880.
ARNOLD BUDENBERG, of Manchester, in the County of Lancaster. " IMPROVE-
MENTS IN APPARATUS FOR LIFTING AND FORCING WATER AND OTHER FLUIDS."
A communication from abroad by Christian Frederick Budenberg, of the Firm
of Schäffer and Budenberg, of Buckau, Magdeburg, Germany.
These improvements relate to apparatus used for lifting and forcing water and
other fluids by the direct action of steam, and consist in providing an injection of

page_text: water or other fluid for the purpose of condensing the steam in such a manner that
the quantity of water or other fluid so injected is in proportion to the amount of
water or other fluid delivered by the apparatus. The apparatus which is of the
same general principle as that usually known as the "steam pressure lift pump,"
is provided with two or more separate barrels or chambers having suction valves
at their lower ends. These barrels or chambers may be tapered at the top, or
otherwise formed so that orifices which are there provided for the inlet of steam
may be conveniently near to each other and be included within a steam chamber
common to them both, or all if there are more than two barrels or chambers. The
orifices herein before mentioned are capable of being closed or opened by means of a
valve or valves mounted on a point, pivot, or knife edge in such a manner that it
may have communicated to it a rocking motion, so that when one part of the valve
closes the orifice beneath it the opposite part of the valve is raised and leaves the
corresponding orifice open, and only one of the orifices beneath the valve can be
open at a given instant when the apparatus has two barrels only. The barrels or
chambers are in communication with each other by means of curved pipes. Each
of these pipes has its opening pointing downwards in one of the barrels or chambers,
and thence passes into the adjoining barrel or chamber, where its opening is
directed upwards; the lower opening may be placed near to the suction valve,
herein before mentioned, and the upper opening of the pipe in the adjoining barrel
or chamber is carried to a convenient height, and is provided with a back pressure
valve. At or near the bottom of each barrel or chamber is another opening for the
delivery of the water or other fluid, each of such openings communicating with a
delivery pipe, and being protected with a back pressure valve, while at or near the
top of each barrel or chamber an air or vent valve is inserted. From the foregoing
description of the apparatus it will be seen that steam can pass into only one
chamber or barrel at once, and that the adjoining barrel is then closed against the
admission of steam. The pressure of the steam then forces the water contained in
the barrel or chamber through the delivery pipe, and this having been accomplished
the steam encounters a sudden reduction of pressure, which causes the swivel valve
to close and thus stop the further admission of steam, the same action raising the
opposite portion of the valve and giving admission of steam to the opposite barrel
or chamber. The further entrance of steam having been prevented, as herein
before described, the then existing excess of pressure contained in the adjoining
barrel or chamber drives a portion of the water contained in that barrel through
the curved pipe, previously described, into the barrel in which condensation is going
on and thus hastens the condensation. The back pressure valves on the upper
openings of the curved pipes allow the injection to take place only in that barrel
or barrels in which the condensation is going on and during the period of conden-
sation. By the condensation of steam a vacuum or partial vacuum is produced,
and as a well known result the suction valve is raised, and the water or other
fluid flows into the barrel or chamber. These operations are repeated alternately
in each barrel or chamber, as in the case of the steam pressure lifting pump and
other similar and well known apparati, with the difference that the condensation
of the steam by means of the injection of water or other fluid from one barrel to
the other considerably hastens the operation, and thereby increases the number of
"beats" and the quantity of fluid delivered in a given time. In order that the
Invention may be the more readily understood and carried into practical effect I
have hereunto annexed a Sheet of Drawings, to which the following description
relates, in which the same letters or letters and figures indicate the same parts.
Figure 1 is a sectional view taken vertically through the two barrels or chambers,
and Figure 2 is a sectional view taken transversely through one of the chambers,
while Fig. 3 is a detail view in a larger scale, showing the valve seats in plan.
A and Al are the barrels or chambers; B and B are the ports leading to the back
pressure valves (C and C¹) and the outlet (G and G¹); D is one of the back pressure
valves;
F is the water inlet; H and H 1, the steam ports; L and L1, the air
valves; R and R 1 the curved injection pipes communicating from one barrel or

page_text: chamber to the other; S and S1, the suction valves; X and X1 are the back
pressure valves to the injection pipes; e and el are the open ends of the injection
pipes; and 1 are perforated covers to the injection pipes. In operating the
apparatus the steam is admitted by means of a stop cock to the space above the
rocking or oscillating valve f. As this valve is capable of closing only one of
the ports H, H1, at the same time the steam is always free to enter one of the
barrels A, A 1. The steam having been allowed to enter one of the barrels for a
short time is turned off for a few seconds, during which time the steam condenses
and a partial vacuum is produced, and water enters by the suction valve S or S1;
the port leading to the other barrel is then open, and the steam being again turned
on enters that barrel, when it is again turned off by means of the stop cock, and
the process of condensation and suction is repeated in the second barrel. The steam
having thus been turned on and off a few times the pump is in full action, and the
steam is allowed to remain turned full on as long as the apparatus is required to
work. The port H being open at the commencement of a double beat steam is
admitted to the barrel A, which already contains water or other fluid, by its
pressure and expansive force it drives the water through the port B, the back
pressure valve C, and the outlet G; it also at the same time forces a portion of the
water through the injection pipe R1 into the barrel A 1. The barrel A 1 being
then full of steam the injected water serves to hasten its condensation and thus to
increase the rapidity of the action of the pump. The steam continuing to enter
barrel A drives the water before it until the port B being reached a large increase
of space and area is encountered suddenly, and a corresponding diminution of
pressure taking place the part of the valve f over the port H falls or is drawn
downwards, closing that port and opening the port H1 to the barrel A 1, where
the process is repeated. It will be understood that as the steam condenses in
barrel A by the united action of the cold vessel and the injection the water rises
through the suction valve S to take its place. The apparatus may be constructed
of any suitable material, but it is preferable to form it wholly of metal, as in the
case of the well known steam pressure lift pump already referred to. Having thus
particularly described the nature of the said Invention as communicated to me from
abroad, and in what manner the same is to be carried into effect, I wish it to be
understood that I do not confine myseif to the precise details, as the same may be
varied without departing from the Invention, and that I claim,-
First. The injection apparatus for facilitating the condensation of the steam,
substantially as and for the purpose hereinbefore described, and illustrated on the
accompanying Drawing.
Second. The rocking or oscillating steam valve in combination with the other
parts of the apparatus, substantially as and for the purpose herein before set forth
and described.
In witness whereof, I, the said Arnold Budenberg, have hereunto set iny
hand and seal, this Thirtieth day of July, A.D. 1880.
