PROVEMENTS IN AND APPARATUS FOR PUMPING LIQUIDS AND PUMPING AND
CONDENSING GASES, SUCH APPARATUS BEING ALSO APPLICABLE FOR USE AS A
BLOWING OR EXHAUSTING ENGINE."
My Invention relates to an improved 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; also my improved apparatus can be used as a blowing or exhausting
engine for ventilating or other purposes.
The principle embodied in my Invention consists in the liquid gas or air being
set in motion or pumped by causing columns of liquid to intermittently change
their level by the action of steam or air pressure supplied through a suitable slide
or other valve.
An apparatus constructed according to my Invention may consist of two suitably
shaped tubes or vessels joined together at their base and partially filled with liquid,
steam or other pressure is intermittently applied to the liquid in vessel number
one, thus causing the liquid to change its level and rise and fall in vessel number
two. The pressure may be applied intermittently to vessel number one through
a slide valve, or by other suitable means. Vessel number two is provided with
suitable valves so that as the liquid rises and falls fresh liquid, gas, or air is drawn
in and then discharged in any required direction.
At or near the bases of the vessels are seatings on which the floats at the
extremity of the stroke may rest, thus forming a joint and preventing the liquor
being forced too far.
A convenient method of applying my Invention consists in duplicating the before-
described tubes or vessels. The duplicates being placed side by side and vessels
number one being fitted with a casing having ports and provided with an ordinary

the said George Steward Hazlehurst in the Great Seal Patent Office on the
14th December 1876.

PROVEMENTS IN AND APPARATUS FOR PUMPING LIQUIDS AND PUMPING AND
CONDENSING GASES, SUCH APPARATUS BEING ALSO APPLICABLE FOR USE AS A
BLOWING OR EXHAUSTING ENGINE."
My Invention relates to an improved 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; also my improved apparatus can be used as a blowing or exhausting
engine for ventilating or other purposes.
The principle embodied in my Invention consists in the liquid gas or air being
put in motion or pumped by causing columns of liquid to intermittently change
their level by the action of steain or air pressure applied through a suitable slide or
other valve.
An apparatus constructed according to my Invention may consist of two suitably
shaped tubes or vessels joined together at their base and partially filled with liquid
or liquids of different specific gravity. Steam or other pressure is intermittently
applied to the liquid in vessel number one, thus causing the liquid to change its
level and rise and fall in vessel number two. The pressure may be applied inter-
mittently to vessel number one through a slide valve, or by other suitable means.
Vessel number two is provided with suitable valves so that as the liquid rises and falls
fresh liquid, gas, or air is drawn in and then discharged in any required direction.
At or near the bases of the vessels are seatings on which the floats at the ex-
tremity of the stroke may rest, thus forming a joint and preventing the liquor being
forced too far, or, if necessary, suitable diaphragms may be substituted for the floats.
A convenient method of applying my Invention consists in duplicating the
before-described tubes or vessels. The duplicates being placed side by side and
vessels number one being fitted with a casing having ports and provided with an
ordinary slide valve so that steam can be admitted to one vessel and then to the
adjacent vessel, each being alternately open to the exhaust.
By this arrangement an alternating motion of two columns of liquid is obtained
and thereby a double action pump. If desirable an expansion valve may be fitted
and floats of any suitable material may rest on the liquid in either tube.

ments of its particular use.
DESCRIPTION OF DRAWINGS.
Figure 1 sectional elevation of an apparatus constructed according to my Inven-
tion; Figure 2 section through A, B, Figure 1; Figure 3 section through C, D,
Figure 1. Like letters on the Drawings are used to denote similar parts.
The apparatus consists of two vessels A, B, joined together at their base C, and
partially filled with liquid. The convenient form of apparatus is the duplex, as
shown in the Drawings, namely vessels A, A¹, joined to vessels B, B¹, by the base
chambers C, C¹. The vessels A, A¹, are provided with steam ports a, a¹, and
exhaust port b, also with a slide valve E worked by a rod F, obtaining its motion
from an eccentric or other suitable means; H, steam pipe; K, exhaust pipe; L, M,
floats; N, O, suction and discharge valves of the vessels B, B¹. These valves may
be of any usual description, or may consist merely of a flat plate over the port
prevented from rising more than a proper distance by overhanging stops at the
corners, no hinge of any sort being required.
In operation steam is admitted alternately into the vessels A, A¹, which are
partially filled with liquid. The steam is alternately exhausted from the vessels
A, A¹, by the exhaust port b. This action causes an intermittent changing of the
level of the liquid in the vessels B, B¹. The result is that the upper portions S, S¹,
of the vessels B, B1, are alternately filled with liquid, air, or gas through the
suction valves N, N¹, and afterwards discharge such liquid gas or air through the
valves 0, 0¹.
Having thus described my Invention, and shown how the same may be put into
practice, I would have it understood that I do not confine myself to the exact
dimensions or arrangement of parts of the apparatus, as shown in the Drawings, as
the same may be considerably varied without departing from my Invention; but
what I claim as my Invention and secured to me by Letters Patent as aforesaid
is, the improvements in and apparatus for pumping liquids and pumping and
condensing gases, such apparatus being also applicable for use as a blowing or
exhausting engine, as set forth in the before-going Specification, and such as
illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said George Steward Hazlehurst, have hereunto
set my hand and seal, this Seventh day of December, in the yoar of our
Lord One thousand eight hundred and seventy-six,
GEORGE STEWARD (L.S.) HAZLEHURST..
