HENRY BODEN, of 17, Brighton Terrace, Victoria Park, in the County of
Middlesex. "IMPROVEMENTS IN OBTAINING MOTIVE POWER AND IN THE APPARATUS
EMPLOYED THEREIN."
My Invention relates to an improved mode of and apparatus for obtaining motive
power, and consists essentially in the utilization of the combined force of air and
water by means of a reversible drum, wheel, or turbine enclosed in a perforated and
jacketed cylinder. Valves are provided over the perforations, which connect the
jacket of the machine with the inside cylinder in which the wheel rotates, which
may be opened or closed as occasion requires. The inner cylinder containing the
turbine or wheel may be partially or wholly filled with water or remain entirely
empty until the valves are opened, as may be deemed expedient. One or more
outlets from the inner cylinder may be provided passing through the jacket above
mentioned, but perfectly independent of and uninfluenced by the pressure of the
said jacket. These outlets which communicate with the atmosphere are provided
with cocks which may be opened or closed at pleasure. In carrying out my
Invention I provide above and in connection with the jacket of the cylinder a
chamber containing air which is compressed to the requisite degree by forcing
water obtained from a tank or other similar receptacle into the apparatus up to the
desired level within the said air chamber by the aid of a pump mounted upon the
same axis as the wheel or turbine, or the water may be introduced in the first
instance by an auxillary pump if required. Valves are provided for regulating the
inlet of the water to the compressed air chamber and the outlet of the water from
the same, which valves are operated by hand in reverse directions. When it is
required to prepare the apparatus for work both last mentioned valves are opened,
and the pump being set in motion water is forced into the air chamber and thenco
into the jacket of the cylinder until the latter is completely filled. The outlet valve
is then closed, and the motion of the pump being continued the air in the air
chamber will be compressed by the pressure of the water to the requisite degree..
The air chamber may be connected with the pump by means of a tube having a
check valve for preventing the return of the water. When the necessary pressure
is obtained, if it is not required immediately to work the engine, the inlet valve is
closed, but should it be desired to put the engine in operation the inlet valve is left

page_text: open, and the outlet valve is also opened and water will then be discharged into the
jacket of the cylinder and through the perforations on to the circumference of the
turbine, causing the same to rotate and thereby repumping the escaped water from
the tank to the air chamber, and thus retain the power that had been obtained.
I also claim the right of employing cranks and levers between the engine and the
pump to assist in pumping the water back into the air chamber.
