and other Liquids.
I, WILLIAM JOHNSON of Westmead Hopwood near Redditch in the County of
Worcester, Manufacturer do hereby declare the nature of my said invention for
"IMPROVEMENTS IN EJECTORS OR APPARATUS FOR THE RAISING OF WATER AND OTHER
LIQUIDS," to be as follows
:-
This invention relates to means or apparatus for the raising of water and other
liquids from wells, and for like purposes, and which said apparatus are commonly
called ejectors; and the object of my said invention is to simplify the construction,
and to render more efficient, or to increase the efficiency of such apparatus or
instruments, and force the liquid or liquids to be raised, to any given height.
An ejector constructed according to my invention, consists essentially of a hollow
body, having inlet and outlet passages or orifices, through which former, the liquid
enters, and through the latter it is discharged after having been operated upon or
brought into contact with steam, which enters through an inlet communicating with
a nozzle placed centrally within the hollow body, and directed towards the delivery
orifice of the said body.
The outlet is formed as or furnished with a delivery nozzle of special shape; the
entrance to the passage being of a rapidly diminishing diameter, whilst that of the
main portion, generally is either parallel or of a gradually increasing diameter,
the outlet in both instances being equal to the full bore of the delivery pipe. The
object in varying the shape and proportions of the delivery nozzle is to compensate
for the various heights to which it is desired to force the liquid, and also the amount
required to be delivered.
As the result of careful experiment, I have found that the efficiency of the instru-
ment is largely dependent on the proper proportioning and relative positions of
certain parts; particularly the distance between the extremity of the steam nozzle,
and the surface of the entering cone leading to the delivery nozzle. Working with
steam of average pressure, I find the distance alluded to, should be about equal to the

page_text: internal diameter of the delivery nozzle in the smallest part. From the smallest part
of the delivery nozzle to its outer extremity, in the case of the gradually increasing
diameter, a taper of about 1 in 9 is appropriate, and in the case of the parallel nozzle,
I make its length equal to about 9 or 10 times its diameter.
Ejectors of the kind referred to, are frequently lowered into wells, and when these
are narrow, and difficult of access, the apparatus including both suction and steam
pipes is sometimes suspended by means of the delivery pipe. In such cases, the
working is often unsteady, and trouble is occasioned through the joints breaking.
With a view to overcoming this difficulty, I stiffen and strengthen the means of
suspension, by bracing the steam and delivery pipes together. For this purpose, I
apply at suitable intervals a clip formed by preference in two halves and bolted
together; the clips secure the said tubes to one another, but at a suitable distance
apart, so as to avoid the condensing influence of the water in the rising main, upon
the steam passing the adjacent pipe.
Thus the apparatus or instrument consists essentially of a bulbous hollow having at
its lower end a suction pipe, secured by flanges or other suitable means; while at
the upper end of the said chamber, a delivery nozzle or tube of special proportions is
secured.
Situated within the interior or hollow of the chamber, a steam jet or sieam nozzle
is secured, with its outlet or extremity cranked, and presented to the inlet of the
delivery nozzle; and which said jet is disposed centrally, and in axial line with the
body of the apparatus.
The steam pipe which runs vertically to the axis of the apparatus is connected to
the jet, by an elbow or bend connection, and through which pipe, steam, compressed
air or other fluid is conducted at a pressure suitable to operate the ejector.
The outer end of the delivery nozzle is connected to a delivery pipe, for conveying
away the fluid raised.
.
The steam pipe and the delivery pipe is provided with a clip for securing them
together.
The action of the apparatus or instrument is as follows.
Upon a jet of steam issuing from the nozzle aforesaid, a vacuum or a partial
vacuum is thereby created in the chamber of the body part, and in the suction pipe
of the apparatus; and in consequence of which, liquid is drawn into the instrument and
elevated or raised to the required height, with a velocity varying, with the pressure of
the actuating fluid.
.
Instead of steam, compressed air or other fluid may be used as the actuating
fluid.

Improvements in Ejectors or Apparatus for the Raising of Water
and other Liquids.
I, WILLIAM JOHNSON of Westmead, Hopwood near Redditch in the County of
Worcester, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to means or apparatus for the raising of water and other
liquids from wells, and for like purposes, and which said apparatus are commonly
called ejectors; and the object of my said invention is to simplify the construction,
and to render more efficient, or to increase the efficiency of such apparatus or
instruments, and force the liquid or liquids to be raised, to any given height.
An ejector constructed according to my invention, consists essentially of a hollow
body, having inlet and outlet passages or orifices, through which former, the liquid
enters, and through the latter it is discharged, after having been operated upon, or
brought into contact with steam, which enters through an inlet communicating with a
nozzle placed centrally within the hollow body, and directed towards the delivery
orifice of the said body.
The outlet is formed as, or furnished with a delivery nozzle of special shape.
As the result of careful experiment, I have found that the efficiency of the instru-
ment is largely dependent on the proper proportioning and relative positions of certain
parts, particularly the distance between the extremity of the steam nozzle, and the
surface of the entering cone leading to the delivery nozzle.
Working with steam of average pressure, I find the distance alluded to, should be
about equal to the internal diameter of the delivery nozzle in the smallest part. From
the smallest part of the delivery nozzle to its outer extremity, in the case of the
gradually increasing diameter, a taper of about 1 in 9 is appropriate, and in the
case of the parallel nozzle, make its length equal to about 9 or 10 times its
diameter.
Ejectors of the kind referred to, are frequently lowered into wells, and when these
are narrow, and difficult of access, the apparatus including both suction and steam
pipes is sometimes suspended by means of the delivery pipe. In such cases,
the working is often unsteady, and trouble is occasioned through the joints
breaking.
With a view to overcoming this difficulty, I stiffen and strengthen the means of
suspension, by bracing the steam and delivery pipes together. For this purpose, I
apply at suitable intervals, a clip, formed by preference in two halves, and bolted
together; the clips secure the said tubes to one another, but at a suitable distance
apart, so as to avoid the condensing influence of the water in the rising main, upon
the steam passing the adjacent pipe.
Thus the apparatus or instrument consists essentially of a bulbous hollow, having at

page_text: its lower end, a suction pipe, secured by flanges or other suitable means, while at the
upper end of the said chamber, a delivery nozzle or tube of special proportions is
secured.
Situated within the interior or hollow of the chamber, a steam jet or steam nozzle
is secured, with its outlet or extremity cranked, and presented to the inlet of the
delivery nozzle; and which said jet is disposed centrally, and in an axial line with the
body of the apparatus.
The steam pipe which runs vertically to the axis of the apparatus, is connected to
the jet, by an elbow or bend connection, and through which pipe, steam, compressed
air, or other fluid is conducted at a pressure suitable to operate the ejector.
The outer end of the delivery nozzle is connected to a delivery pipe, for conveying
away the fluid raised.
The steam pipe, and the delivery pipe, are provided with a clip, for securing them
together.
The action of the apparatus or instrument is as follows.
Upon a jet of steam issuing from the nozzle aforesaid, a vacuum, or a partial
vacuum is thereby created in the chamber of the body part, and in the suction pipe
of the apparatus; and in consequence of which, liquid is drawn into the instrument,
and elevated or raised to the required height, with a velocity varying with the
pressure of the actuating fluid.
Instead of steam, compressed air or other fluid, may be used as the actuating
fluid.
I will now proceed to describe with reference to the accompanying drawing, the
manner in which the same is to be performed.
Figure 1 represents in side elevation, and figure 2 a complete vertical section of an
ejector or liquid raiser, constructed and arranged, according to my invention. Figure 3
is a transverse vertical section of the same, on the dotted lines A B, figure 2, looking
downwards.
The same letters of reference indicate corresponding parts in the several figures.
a is the body of the instrument, internally swelled, with a bulbous chamber part a³,
about its middle, and which said body part has at its lower end, a suction inlet a³,
encircled on its outer edge, by a flange a, to which a suction pipe b, by its flange b²,
is connected.
The said suction pipe is of the same internal bore or diameter, as the suction
inlet a³.
Directed horizontally into the middle of the internal swell, or chamber part a³, of
the body a, is a steam nozzle c, with its nose or inner end c³, cranked or turned
upwardly, and with the said turned up part, which of a gradual taper, from
horizontal bore to nose end, is directed centrally, in the same axial line as the
delivery pipe d above it.
The rear end of the steam nozzle c, has a screwed neck c³, upon which an
elbow c* is screwed, and to which elbow joint, a vertically directed steam pipe e, is
connected.
The bore of the delivery nozzle d, is of a gradually increasing taper, from near the
lower part, to its connection with the delivery pipe; that is, the bore d², has a
clearance part d³, of the same internal diameter, or thereabouts, as the delivery pipe f
above it, and whose flanged ends f, are secured by bolts and nuts, to the upper
flanged ends d', of the delivery nozzle d; while the lower part d', is of about one
third the diameter of the other end, to which it gradually tapers.
The striking part d' at the said lower end, widens out, or evolves itself into the
internal swell or bulbous part a* of the body a.
The lower part of the delivery nozzle, has a neck do, with a flange d', of which the
former fits into a socketed part c, and with the respective flanges connected
together by nuts and bolts.
is a segmental clip, embracing and connecting together the delivery pipe, and
steam pipe; and by means of which, the instrument admits of being suspended, when
raising water from a well or the like,

page_text: The action of the instrument is as follows.-
By steam or other fluid issuing from the nose c², of the nozzle c, a vacuum is
created within the chamber a², and at the striking part d by condensation, and in
consequence of which, liquid to be raised, is drawn into the instrument, through its
suction pipe 6, into the hollow body a³, and from thence subsequently raised to the
desired height, through passage d² of delivery nozzle d, and delivery pipe f
The raising or forcing of the liquid in the delivery pipe, is at a velocity, varying
with the pressure of the steam or actuating fluid.
In practise, I have found the following, to produce the best results.
Taking an instrument having suction and delivery pipes, with respective internal
diameters of one inch as a standard of comparison, I make the bore of the steam
nozzle about five sixteenths of an inch in diameter, tapering to nose, to about three
sixteenths, and that of the delivery nozzle passage, three eighths of an inch near the
entrance, and widening out to the internal size of the delivery pipe.
The distance between the outlet of the steam nozzle, and the cone or striking part d³,
of the delivery pipe, should be about a quarter of an inch.
By slightly reducing the diameter of the steam nozzle, a considerable increase of
effect is produced, in the volume of liquid delivered, and the height or distance to
which it is forced.
Instead of the ejector or instrument being made in segments as described, it may
be made solid, or in one piece.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
First. The combination with an ejector, or apparatus, for the raising of water and
other liquids, of a steam nozzle c, whose nose part c³, comes within a given distance,
of the inlet to the delivery nozzle, and which said steam nozzle, is constructed and
arranged, with respect to the other parts, substantially as described and set forth.
Secondly. Surrounding, or providing, in the vicinity of a steam nozzle, of a
circumadjacent chamber, or clearance a³, substantially as described and set forth.
Thirdly.-Making, or constructing delivery nozzles d of ejectors, or liquid raisers,
of a passage or bore d², d³, d, ds, substantially as set forth.
Fourthly. Providing the outlets or exits, of delivery nozzles d, with a clearance d³,
substantially as described and set forth.
Fifthly. The combination with an ejector, or liquid raiser of clearances a², d³, as
herein described and set forth.
Sixthly. Connecting the delivery and steam pipes, and also suspending ejectors or
water raisers, by a clip g, g', substantially as described and set forth.
Seventhly. An ejector, or apparatus for the raising and forcing of water and other
liquids, consisting essentially of a body a, bulbous chamber or clearance a³, suction
inlet a³, and steam nozzle c, c², while the upper part of the instrument consists of a
delivery nozzle d, d², d³, d, and d³; and which said parts are constructed, arranged
and combined with respect to each other, substantially as, and for the purpose, as
herein described and set forth.
Lastly. An instrument or apparatus for the raising of water and other liquids, by
compressed air, substantially as described and set forth.
