page_text: LETTERS PATENT to William Rainbow, of 5, Southampton Buildings, in the
County of Middlesex, for an Invention of "IMPROVED METHOD OF AND
APPARATUS FOR RAISING AND FORCING WATER AND OTHER LIQUIDS."
PROVISIONAL SPECIFICATION left by the said William Rainbow at the
Office of the Commissioners of Patents on the 23rd September 1881.
WILLIAM RAINBOW, of 5, Southampton Buildings, in the County of Middlesex.
"IMPROVED METHOD OF AND APPARATUS FOR RAISING AND FORCING WATER
AND OTHER LIQUIDS."
The object of this Invention is for raising and forcing water or other liquids to
any desired distance without the employment of pumps as heretofore.
According to this Invention I inject steam or air into the pipe that communicates
with the water in a well (for example), so as to form a suction in such pipe, and
also force it through a continuous or another pipe or pipes to the required
distance.
The above may be effected in a variety of ways, one of which is as follows:-
To the pipe that communicates with the water I connect a hollow ball at about
10 feet above the level, and to the said ball I connect a jet communicating with a
steam boiler, so as to introduce steam into the said ball. I also connect one end
of the outlet pipe to the said ball so as to convey the water to the required place,
the water being forced from the said pipe by the pressure of the steam.

by the said William Rainbow in the Great Seal Patent Office on the
23rd March 1882.
WILLIAM RAINBOW, of 5, Southampton Buildings, in the County of Middlesex.
"IMPROVED METHOD OF AND APPARATUS FOR RAISING AND FORCING WATER
AND OTHER LIQUIDS."
My Invention relates to improved apparatus for raising and forcing water and
other liquids by the action of a jet of steam or air injected through a nozzle and
receiving cone fitted within a bulb or vessel, as hereafter described, the apparatus
being applicable for raising water from a well, river, pond, or other source, tank,
vat, or other container, ship's bilge, or other place to any desired distance, or, with
slight modification, as an injector for forcing water into a steam boiler against tho
pressure of steam therein.
In order that the Invention may be more readily understood, I have illustrated
it in the accompanying Drawings, and will proceed to describe it with reference
thereto. Figure 1 is an external view of the apparatus, and Figures 2 and 3 are
sections at right angles of the same as adapted for raising water or other liquid.
A is the suction pipe communicating with the well or other place from which
the water is to be raised; B is a hollow bulb screwed upon the pipe A at a point
not exceeding 25 feet abovo the level of the water to be raised, although it may be
situated at any point below such level. This bulb is traversed by a tubular
chamber C (preferably cast in one with the bulb), whose sectional area compared to
the diameter of the bulb should be in about the proportion shown, so as to leave
a free passage around said chamber C from the suction pipe A to the delivery pipe.
This tube C is closed at one end by a screw plug c, removable for blowing out any
obstruction which may lodge in the bulb or pipe, and its other end is in communi-
cation with a pipe D connected to the steam boiler or compressed air chamber,
according as a jet of steam or air is used, which pipe is screwed into the bulb, as
shown; E is the delivery pipe connected to the bulb B by a screw coupling, as
shown, and leading to the point of discharge, which may be at any height,
according to the pressure of steam or air available; F is a nozzle communicating
with the chamber C, and G is the receiving cone fitted within the orifice of the
delivery pipe E, the nozzle F and cone G being in the same axial line, and being as
regards their proximity and sectional area in about the proportions shown with
regard to the dimensions of the chamber C and bulb B. For the purpose of raising
water it will be observed that the receiving cone G has its smaller orifice towards
the nozzle F, and its larger orifice towards the pipe E. It is essential that the
lower orifice of the cone G be flared or trumpet mouthed, as shown at g, as it is
upon this form that the desired suction mainly depends.
In operation the jet of steam or air issuing from nozzle F and directed towards
the opposite flared orifice g of the cone G causes a suction in the pipe A and bulb B,
thereby forming a partial vacuum therein, which is immediately filled by the
water or other liquid rising in the suction pipe and bulb, which water or other liquid
is carried along with the jet through the cone G, and forced by the pressure of the
steam or air through the pipe E to the height or distance required. Figure 4
illustrates a section of the apparatus as modified for uso as an injector for feeding
steam boilers. It will be observed that the nozzle F is longer and projects partly
through the cone G, which is reversed in position to that previously described, its
larger orifice being towards the nozzle, and its smaller orifice towards the pipe E.
The apparatus may also be used for exhausting gases, foul air from mines, and
similar purposes,

page_text: Having described the nature of my Invention and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
hereinbefore in part recited Letters Patent is,-
1st. The construction, combination, and arrangement of parts constituting the
improved apparatus, substantially as and for the purposes berein shown and
described.
2nd. The water raising apparatus, constructed and operating substantially as
shown and described.
In witness whereof, I, the said William Rainbow, have hereunto set my
hand and seal, this Twenty second day of March, A.D. 1882.
