page_text: I, FREDERICK BARKER HILL of 69 Campling Road, New Cross Gate, in the
County of Kent, Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR THE LIFTING AND DISCHARGING OF FLUIDS,
AND WHICH IS ALSO APPLICABLE FOR OTHER PURPOSES to be as follows:-
My invention is for improvements in apparatus where the raising and discharging
of fluids is effected by the alternate condensation and pressure of steam.
My improved apparatus, consists of a vessel, (or vessels) of a suitable shape
fitted at bottom with suction and delivery valves the latter being connected to
a discharge pipe or rising main. Through the top of the said vessel is inserted a
tube the length of which regulates the quantity of water or fluid at each discharge,
and which is open at top and bottom. The top may be fitted with a valve-The
tops of the said vessel and the said internal tube are connected to a chamber fitted
with a valve to be worked either by a float steam or otherwise. The discharge of
the delivery pipe may be increased by fitting to it an ejector which when the
apparatus is used on board steam vessels may also be utilized for the discliarge of
the ashes To prevent the too rapid condensation of steam on the surface of the
water or fluid in the said vessel I use oil or other oleaginous matter either alone or
in combination with a float.

water in the said tube e falls by gravity and the float f falling with it strikes
the collar e² on the spindle e¹ thereby moving the valve or cock and closing the
inlet from g The exhaust steam then passes through the passage g' and the
pipe g into the rising main g³ by the apertures 9 A vacuum due to the con-
densation of steam or to the velocity of the water in the rising main is thereby
formed. A similar action now takes place in the other vessel A.
When the pressure of steam used is greater than required to raise the water to
a given height the discharge of the water may be increased by an induced current
caused by leading the water from the pumping apparatus through an ejector as
shewn in Fig: 4.-The ejector must be below the surface of the water which has
to be raised.
In order to prevent the too rapid condensation of steam on the surface of the
water in the vessels A I use oil or oleaginous matter alone or in combination with
a float and to prevent the said oil from passing away at the end of each discharge
I regulate the length of the tube e so that the delivery valve has always a covering
of water.
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 general arrangement and construction of the apparatus for raising
and forcing water or other liquid substantially as represented and described.
Secondly: The construction and arrangement of the floats f and the tubes e for
the purpose of regulating the quantity of water at each discharge and for getting
rid of the exhaust steam freely and thereby allowing this description of pump to
be jacketted with a non-conducting material substantially as and for the purpose
herein before described.
:
Thirdly The combination with the pump of the ejector shown in Fig: 4 and
described.
And lastly: The use of the oleaginous matter for the purpose of preventing too
rapid condensation substantially as hereinbefore described.
