« IM-
AND
My Invention relates to a novel method of and a novel form of apparatus for
pumping liquids, whether acid, alkaline, neutral, corrosive, or non-corrosive, and for
pumping and condensing gases, whether acid, alkaline, neutral, corrosive, or non-
corrosive.
An apparatus constructed according to my Invention consists of two dished discs
or their equivalent of iron or other suitable material, lined with india-rubber or
otherwise, which are bolted together and divided by an india-rubber or other
flexible diaphragm.
The discs are respectively provided with branches, one of which is connected to a
water, steam, or air motor, being a pump, direct steam pressure, or other suitable
contrivance. The branch from the other disc is in connection with a pipe, which for
a simple pump connects to suitable suction and discharge valves.
Where my Invention is applied to pumping and condensing gases I connect the
pipe from the second disc to a vertical chamber, which communicates by means of
an inlet valve to the gas supply, and by a weighted outlet valve to a gas discharge.
In condensing the vertical chamber is provided with a series of blocks to retain
the gas.
In operation the chamber and pipe and disc are filled with liquor, which liquor
may fill the chamber at the top of the stroke. The action of the engine, pump, or
other motor actuates the flexible diaphragm between the dished discs, and thus
causes a continuous upward and downward movement of the liquor in the vertical
chamber, which in its turn acts as a pump and sucks the gas into the chamber, and
by the return of the stroke compresses and condenses the gas into the liquor. The

The flexible diaphragm need not necessarily be of india-rubber, as other material
may be used, but in all cases where acids or liquors are used which would
detrimentally affect the diaphragm, whether of india-rubber or otherwise, such
diaphragm must be covered over with some suitable protective material or com-

or medium to compensate for leakage or unequal action in the engine or prime

PROVEMENTS IN
"IM-
AND APPARATUS FOR PUMPING LIQUIDS AND PUMPING AND
CONDENSING GASES."
My Invention relates to a novel method of and a novel form of apparatus .for
pumping liquids, whether acid, alkaline, neutral, corrosive, or non-corrosive, and for
pumping and condensing gases, whether acid, alkaline, neutral, corrosive, or non-
corrosive.
An apparatus constructed according to my Invention consists of two dished discs
or their equivalent of iron or other suitable material, lined with india-rubber or
otherwise, which are bolted together and divided by an india-rubber or other
flexible diaphragm,
The discs are respectively provided with branches, one of which is connected to a
water, steam, or air motor, being a pump, direct pressure, or other suitable con-
trivance. The branch from the other disc is in connection with a pipe which for a
simple pump connects to suitable suction and discharge valves.
Where my Invention is applied to pumping and condensing gases I connect the
pipe from the second disc to a vertical chamber, which communicates by means of
nn inlet valve to the gas supply, and by a weighted outlet valve to a gas discharge.
In condensing the vertical chamber is provided with a series of blocks to retain the
gas, if necessary.
In operation the chamber and pipe and disc are supplied with liquor, which liquor
may fill the chamber at the top of the stroke. The action of the engine, pump, or
other motor actuates the flexible diaphragm between the dished discs, and thus
causes a continuous upward and downward movement of the liquor in tho vertical
.chamber, which in its turn acts as a pump and sucks the gas into the chamber, and
by the return of the stroke compresses and condenses the gas into the liquor. The
surplus gas and air escapes through the weighted discharge valve, and is passed
under water through tubes or vessels, which may be put under pressure by a weighted
valve at the exit, and suitably packed and moistened or otherwise.
The flexible diaphragm need not necessarily be of india-rubber, as other material
may be used, but in all cases where acids or liquids are used which would detri-
mentally affect the diaphragm, whether of india-rubber or otherwise, such diaphragm
must be covered over with some suitable protective material or composition.
In pumping I provide the first dished disc with a suitable escape or outlet valve
or medium to compensate for leakage or unequal action in the engine or prime
motor. A small tap is inserted under the diaphragm in condensing to discharge
the air when the pipe or chamber is being filled.
The nature, object, and purposes of this iny Invention having been set forth as
above I will now proceed to describe how the same may be carried out, and for
that purpose I have hereunto attached a Sheet of Drawings, which sufficiently
illustrate my Invention to enable any person acquainted with mechanics to carry

page_text: the same into practical effect. Like letters and figures marked on the Drawings
denote similar parts throughout the various views.
Figure 1 is a side elevation of an apparatus constructed according to my
Invention; Figure 2 is a front view of Figure 1.
Figure 3 is a front view of a double-acting apparatus constructed according to my
Invention.
Figure 4 is a modification of an apparatus constructed according to my Inven-
tion.

Upon reference to the Drawings it will be seen that a, a¹, are two dished discs
bolted together and divided by the diaphragm b. The diaphragm & may be of india-
rubber or other flexible material. The disc a is provided with a branch c connected
to a water, steain, or air motor. That shown in the Drawings at a represents an
ordinary slide valve, e being the steam supply and the exhaust. The disc a¹ is
provided with a branch which connects to the pipe . For a simple pump I use a
direct pressure from a water pump k, as shown at Figure 4. The branch of the
disc a is fitted with a suction valve and pipe leading to an acid tank l, and the
branch is fitted with a discharge valve, pipe, and air vessel. The tank s is filled
with water, and attached to front end of the pump .
Where my Invention is applied for pumping or condensing gases I connect the
pipe to a vertical pipe or chamber, which communicates by means of an inlet
valve m to the gas supply, and by means of a weighted outlet valve n to a gas
discharge.
The vertical chamber ¹ may if necessary be provided with a series of wooden
blocks to retain the gas.
In operation the chamber and pipe and hand the disc a are supplied with
liquor, which liquor may fill the chamber at the top of the stroke. A small tap
inarked is inserted under the diaphragm in condensing to discharge the air when
the pipe or chamber is being filled. The action of the engine, pump, or other
motor actuates the flexible diaphragm between the discs a, a, and thus causes a
continuous upward and downward movement of the liquor in the vertical chamber ²,
which in its turn acts as a pump and sucks the gas into the chamber through the
valve m, and the return of the stroke compresses and condenses the gas into the
liquor. The surplus gas and air escapes through the weighted discharge valve n,
and is treated as herein-before described.
Having now described and ascertained the nature and construction of my Inven-
tion, and shown how the same may be carried out into practical effect, I would
have it understood that I do not confine myself to the precise dimensions and
details, as shown in the Drawings, but what I claim as my Invention and secured
to me by Letters Patent as aforesaid is,
Firstly. The method of and apparatus for pumping liquids and condensing gases,
herein-before described, such apparatus consisting of two dished discs, such as a, a¹,
in combination with a flexible diaphragm such as b, a pipe such as h, a chamber
such as ', inlet and outlet valves such as m, n, arranged and working in relation
to each other in the manner as shown and set forth.
Secondly. The dished dises e, e, in combination with the flexible diaphragm b,
and the water pump, the inlet and outlet valves g, gl, arranged in relation to
each other, as shown at Figure 4, and working in the manner and for the purposes
specified.
In witness whereof, I, the said George Steward Hazlehurst, have hereunto set
my hand and scal, this Sixth day of July, in the year of our Lord One
thousand eight hundred and seventy-six.
