County of Surrey, Engineer, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SUCKING, COMPRESSING, AND DISCHARGING FLUIDS FOR
MOTIVE POWER OR OTHER PURPOSES."
Sealed the 11th February 1879, and dated the 15th August 1878.
PROVISIONAL SPECIFICATION left by the said James Graddon at the Office
of the Commissioners of Patents on the 15th August 1878.
JAMES GRADDON, of 22, Castelnau Villas, Barnes, in the County of Surrey,
Engineer. "IMPROVEMENTS IN MACHINERY FOR SUCKING, COMPRESSING, AND
DISCHARGING FLUIDS FOR MOTIVE POWER OR OTHER PURPOSES."
The object of my Invention is to suck, compress, & discharge fluids of any
kind into any discription of receiver or receivers by the means as follows for
motive power or other purposes by arranging series of pumps in any required angle,
and caused to force by series of tappet wheels mounted on a shaft employed for
that purpose, a series of springs being arranged over the piston rods of the pumps
to return these pistons after been acted on by the tappits placed on the wheels or
rollers for the purpose of being brought in contact with those tappits fixed on the
pump pistons, which are thereby caused to act one after the other as the tappits are
fixed round in the form of a screw to cause each pump to act single, and thereby
give power, and the quanty of fluid is made up by the number acting in
succession.
I also purpose dispensing with the springs by a back force of fluid produced by
any machinery connected therewith.
I also purpose placeing a small receiver by the side of the large one, and into the
small receiver the fluid is to flow after lifting the piston of the motive-power
C

page_text: cylinder; and into the small receiver a pressure of fluid is to be passed at intervals
from the large one, and thereby pass water or other heavy fluid into the large one
by means of valve suction and force pumps connected therewith.
And I purpos causeing one pump to act over the piston of the driveing cylinder
after all the valves are closed, and thereby a second power is gained on the motive-
power cylinder, the piston of which is acted on by a small pump at the moment the
slide valve passes over the port thereof, and stops off the power of the large
receiver which containes the compressed fluids when those pumps are employed for
motive power and when for pumping fluid from mines or other places.
purpose employing them with or without a air vessell.

the said James Graddon in the Great Seal Patent Office on the 15th February

JAMES GRADDON, of 22, Castlenau Villas, Barnes, in the County of Surrey,
Engineer. "IMPROVEMENTS IN MACHINERY FOR SUCKING, COMPRESSING, AND
DISCHARGING FLUIDS FOR MOTIVE POWER OR OTHER PUrposes."
The object of my Invention is to suck, compress, and discharge fluids of any
kind into any description of receiver or receivers for motive power or other purposes.
I arrange a series of pumps at any required angle, and I cause these to move by a
series of tappets on wheels mounted on a shaft, a series of springs being arranged
over the piston rods of the pumps to return the pistons after being acted on by the
tappets. The tappets are fixed on the series of wheels in the form of a screw to
cause each pump to act single and in succession to give power, the quantity of fluid
being made up by the number of pumps acting in succession.
In some cases the springs can be dispensed with, and then a back force of fluid
produced by any machine connected therewith returns the piston.
I purpose placing a small receiver by the side of the larger one, and unto the
small receiver the fluid is to flow after lifting the piston of the motive-power
cylinder and into the small receiver. A pressure of fluid is to be passed at intervals
from the larger one and thereby press water or other heavy fluid into the larger
one by means of valves and suction and force pump connected therewith.
I also purpose causing one pump to act on the piston of the driving cylinder
after all the valves are closed, whereby a second power is gained on the motive-
power cylinder, the piston of which is acted on by a small pump at the moment the
slide valves pass over the ports thereof to shut off the power of the larger
receiver which contains the compressed fluid, especially when these pumps are
employed for motive power or when for pumping fluids from mines or other places.
I purpose employing them with or without an air vessel.
The annexed Drawings, Figures 1 and 2, represent my Invention as above set
forth.
A is the large receiver into which air or other fluid is forced by a pump; B is
the steam cylinder for actuating the wheel D by the pinion E and the connecting
rod F. The wheel D is on a shaft G on which the series of wheels H, H, are
mounted, these wheels carrying tappets or roller projections I, I, arranged in spiral
or threaded order upon them as to act in succession and lift the rods J, J, and
pistons of water pumps K, K, as the wheels H, H, revolve, the lifts causing water
to rise into the pump barrels from any source of supply by the pipe L.
When the tappets escape by the revolution of the wheels from the rods J, J, the
pistons of the pumps are caused to descend under the action of the springs M, M, which
force the water from the barrels into a cylinder, and cause that engine to act upon
any machinery it may be connected to force the inflowing water to the cylinder.
The action of the springs causes the outflowing water to pass into the receiver A
under this pressure, and so assist in compressing the air that is within the receiver
in conjunction with the air entering from air pump as to produce a power therein
that can be utilized to push the water from the receiver to work an engine.
Figure 3 shows the small vessel or receiver detached. This receiver, by an
internal pressure of air and water which are supplied to it from the
pumps, assists
the action of the pressure to the large receiver, and maintain the supply therein.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim the apparatus herein shown, and its

other purposes, as set forth.
In witness whereof, I, the said James Graddon, have hereunto set my hand
and seal, this Fifteenth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
JAMES GRADDON. (L.S.)
