Improvements in Automatic Water Raisers.
I, EDWARD CORY of 5 Church Road Castelnau, Barnes in the County of Surrey,
Civil Engineer, do hereby declare the nature of this invention to be as follows :-
The object of this invention is the construction of an apparatus for raising water,
which when started may be left entirely to itself, and with the exception of a suction
and delivery valve, shall have no working parts and require no oil or lubrication.
I construct the apparatus in the following manner-A receptacle or boiler is filled
with water and is made to generate steam by heating with gas, oil or otherwise, in
such a way that a regular supply of heat is communicated to the water. Adjoining
or surrounding this boiler is a second receiver communicating at its upper end with
the top part of the boiler, and connected with a pipe at its lower end with the stand
pipe, through which the water is delivered. From the upper part of the same receiver
is a syphon pipe bending downwards, which is led into the stand pipe at a higher level
than the pipe from the bottom of the receiver, and conducted upwards inside the stand
pipe to a height above the top of the boiler. The stand pipe surrounding the syphon
pipe is enlarged to form a receptacle for condensing the steam formed. At the bottom
of the stand pipe is a suction valve, and at the top of the condenser is a delivery valve,
leading into the delivery pipe. Near the delivery valve should also be a cock, through
which the whole apparatus can be filled with water.
The action, of the apparatus is as follows; Steam is generated in the boiler which
rises to the top of same, filling the upper part of the adjoining receiver and the upper
part of the syphon pipe leading from same. The pressure of the steam drives the
water in the receiver and in the syphon pipe downwards through the pipe at the
bottom of the receiver, and through the syphon pipe, into the stand pipe, and out
through the delivery valve. This goes on till the steam reaches the bend in the
syphon pipe, when being free to escape it passes up the long leg of the syphon;
inside the stand pipe, into the condenser, and at the same time the water in the
condenser, which is above the receiver, descends, entirely filling up again the receiver,
the syphon, and the small portion of the water in the boiler which has been evaporated
into steam. The steam which has passed into the condenser becomes instantly con-
densed, and the partial vacuum is at once filled by water drawn up through the
suction valve. The operation then repeats itself as before described.
The water, which is being raised, passes up the stand pipe and also passes through
the condenser, so that, each time the steam is syphoned out, there is a fresh supply
of cold water drawn into the condenser to condense the steam.
The apparatus can be constructed to work with coal or other fuel, in which case
the heating apparatus would require attention in keeping up the fire.

Improvements in Automatic Water Raisers.
I, EDWARD CORY, of 5 Church Road, Castelnau Barnes, Surrey Civil Engineer
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 apparatus for raising water, or any other liquid capable of being turned into
steam or vapour, is constructed as follows-
Part of the liquid is turned into vapour in a receptacle or boiler provided for the
purpose.

page_text: The vapour, as it forms, drives the water downwards either in the boiler itself
or in an adjoining receiver, an outlet being provided at or near the hottom of this
receiver through which the water or liquid passes, and from thence into the stand
pipe and out through the delivery valve. A syphon pipe leading from the top of the
boiler, or the adjoining receiver, is bent downwards, reaching as far as the level to
which it is desired that the vapour should force the liquid, and from thence upwards
again to a height above the top of the boiler and adjoining receiver, where it joins
the stand pipe below the delivery valve, or the syphon pipe may join the stand pipe
at a lower level and be continued upwards inside the stand pipe. The stand pipe
surrounding the syphon pipe may be enlarged to form a condenser for condensing
the vapour or steam.
When the vapour has driven the liquid down to the level of the bottom of the
syphon pipe the vapour in the boiler and receiver is syphoned out and rises into the
enlarged part of the stand pipe or condenser, where it becomes at once condensed,
forming a partial vacuum which is filled by a fresh supply of liquid drawn in through
the suction valve at or near the bottom of the stand pipe. When the apparatus has
thus become again filled with liquid, the vapour forms again, and drives out a
fresh supply of liquid through the delivery valve, repeating the action as above
described.
The annexed drawings show how the invention may be carried out, but I do not
bind myself to the particular forms of the apparatus shown in the drawings.
On sheet 1, Fig. 1. is a section and Fig. 2 an elevation of the automatic water
raiser. A is the fire chamber communicating with its chimney.
B is the boiler
having an outlet C to the receiver D. and another outlet E to the syphon pipe F.
The bottom of the receiver D communicates with the stand pipe G which is enlarged
at H to form a condenser. I is the suction valve and J the delivery valve com-
municating with the delivery pipe K. L is a cock for filling the apparatus before
starting it, which may be connected by a pipe with the cistern above. The line M
represents the level of the water to be raised, and N. N. are doors for the purpose
of cleaning the apparatus.
When it is desired to work the machine, the whole of the apparatus is filled with
liquid between the suction and delivery valves I and J by turning on the cock L.
This cock is then closed and the fire lighted at A. Steam or vapour rises in the
boiler B escaping through C and E and driving the liquid down in D and F, at the
same time causing liquid to flow up the delivery pipe K. When the vapour in D
and F reaches the level of the bottom of the syphon F, the whole of it escapes up
the long leg of the syphon F into the condenser H, where it becomes condensed and
the partial vacuum is filled by a fresh supply of water drawn in through the suction
valve I. The hot liquid, which has been driven down into the lower part of D, rises
again, filling up the space previously occupied by the steam or vapour, and flowing
into the boiler and syphon pipe B and F. The apparatus therefore again becomes full
of liquid and is ready to repeat the operation above described.
Sheet 1 represents a form of the apparatus suitable for small sizes, but on sheet 2
Fig. 1 a section of a water raiser for larger sizes is given, where the same letters
represent the same parts as above described. In this figure the boiler is provided
with tubes O. O. for rapidly evaporating the liquid. The receiver D surrounds the
boiler. Fire and air doors are provided at P. and P. and a smoke box at Q. The
syphon pipe F is enlarged into a number of pipes inside the condenser H for
more readily condensing the vapour. Where the head of water from the bottom
of the receiver D to the top of the condenser H is considerable it is advisable to
fit to the syphon pipe a non-circulating valve R consisting of a float or ballcock
valve. This valve is floated up to its seat when the apparatus is full of water but
when steam forms it opens and admits it to the syphon. Without this valve a
circulation is likely to be set up caused by the rising of the hot water through the
syphon F into the condenser H, the cold water returning through G to the bottom of
the receiver D.
If the apparatus is to be perfectly automatic, gas, oil or any fuel that can have a

page_text: constant supply should be used, but coal or any other fuel may be adopted, when
attention would be required to keep up the fire. It is also advisable in some cases to
use suction and delivery valve boxes containing two valves in each to prevent any
back leakage.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is-
1. An apparatus for raising or pumping water, or any liquid that can be converted
into vapour, wherein vapour is alternately produced from part of the liquid being
raised, and condensed by being conveyed to a colder part of the apparatus, thereby
alternately producing pressure for the expulsion of the liquid from the apparatus and
a partial vacuum for refilling it, substantially as described.
2. A syphon, for retaining and regulating the discharge of steam or vapour under
pressure, substantially as described.
