of the Commissioners of Patents, with his Petition, on the 4th February
1859.
I, JOHN WOOLLEY HART, of 45, Evelyn Street, Lower Road, Deptford, do
hereby declare the nature of the said Invention for "RAISING WATER OR OTHER
LIQUIDS, AND COMPRESSING AND FORCING FLUIDS, ATMOSPHERIC AIR, OR OTHER
AERIFORM BODIES," to be as follows:-
My Invention consists of an improved method of raising water or any other
liquid body, and of compressing and forcing atmospheric air or any other
aeriform body, the same being applicable to the transmission of power by
compressed air, or air expanded by heat, or by the falling of water, and to tho
raising or forcing of water, or the compressing or forcing of air, wherever
such operations are required separately or conjointly.
My mode of operation is as follows:-I take a tube or cylinder of iron,
copper, brass, or other suitable material, in which I cut a slot or opening
lengthways. I then coil sheet zine or copper or other material round the said
tube, allowing a distance between each wrap of the coil corresponding with
the width of the slot; the two ends of the coil or scroll are then sealed by
moulten lead or cast iron, or by such means as are found to be the most
expedient, a hollow spindle of the same area of opening as the slot is fixed
through the centre of the tuhe or cylinder, such spindle being perforated.
Instead of the above-mentioned coil or scroll, a long flexible tube may be
wrapped in a coil, or in a series of coils round the tube or cylinder, but I
prefer the coil or scroll first mentioned.
I then take a chest of the required dimension of wood or iron, at one end
of which I have another small chest of iron or other material, sufficiently

page_text: strong; one end of the hollow spindle is open and passes through the stuffing
box into the inner strong chest, and to this chest is also attached the pipe or
hose which is to conduct the water to the required height; the other end of
the hollow tube is made solid, and passes through a stuffing box out of the
end of the larger box, and to this end a crank handle is attached, by which the
coil is moved round; this large box is kept just half full of water by a ball-
cock or other suitable contrivance. If then the coil be turned in the proper
direction, it will take up every turn half a circle of water and half a circle of
air, and will force air and water into the iron chest under a pressure corre-
sponding with the number of wraps in the coil or scroll, and in quantity cor-
responding with the width of the coil and the distance of the spaces in the
coil. The water passes. through the before-mentioned discharge tube at the
required height, and the air or gas may be disposed of in any of the following
waysFirstly, it may be passed into a chest containing, water, which it will
force into the receiving chamber; after the compressed air has done this, it
may be allowed to force water from a lower level than the pump or engine
into the supply box for feeding the pump or engine. Secondly, the com-
pressed air may be discharged through a column or a series of columns of
water, each containing a wheel similar in construction to a water-wheel, tho
air rushing in at the bottom of the first compartment or column, and dis-
placing the water in one division of the wheel causes the wheel to rotate,
each division of the wheel having the water displaced as it passes the pipe
which discharges the air. After the air has thus passed through the first
column, it is conducted to the bottom of the second column, and passes in a
similar manner through the second wheel, then through a third or fourth, and
any further number that may be required. By this means power is obtained
which may be applied to assist in working an engine or pump, or in any
other way that may be considered desirable. I also propose to obtain power
by heated air through the same means. Thirdly, I make use of this con
pressed air in working a reciprocating valve pump either as a suction
pump or a force pump, or both together, if required.
