IMPROVEMENTS IN ENGINES FOR OBTAINING MOTIVE POWER
Year: 1884

Tailor do hereby declare the nature of my invention for "IMPROVEMENTS IN
ENGINES FOR OBTAINING MOTIVE POWER" to be as follows:-
This invention has for its object improvements in engines for obtaining motive
power.
The engine is provided with one or more reservoirs for containing water and air
under pressure.
From these reservoirs the fluid is conveyed by pipes to the
working cylinder or cylinders by which the engine is driven. When the engine is
first started the fluid after leaving the working cylinders is allowed to escape but
when the engine has been running a short time and momentum has been acquired
the momentum is utilized to pump back the Buid into the reservoirs and thus
maintain the pressure therein. The power for working the return pumps is taken
from one of the moving parts of the engine (in the case of a locomotive it would
be one of the wheels) and by being transmitted through a series of weighted levers
the power
is increased by the cumulative action of the leverage and weights.
The engine is provided with a cistern of water for replacing that lost when the
engine is started or any which may have escaped through the safety valves. On
the pipe leading from this cistern to the pumps there is an air valve by which a
certain amount of air is drawn in with the water and is forced into the reservoirs
under pressure.
In some cases it may be desirable to heat the reservoirs under pressure if this is
done the steam generated may either be used to work the engine or to increase the
pressure in the reservoir,

The diagram drawings show a locomotive constructed in accordance with my
invention.
Figure 1 shows the arrangement of driving mechanism.
Figure 2 shows the mechanism for pumping the fluid back into the reservoir.
a (Figure 2) is a reservoir under pressure it is provided with a safety valve a¹.
In Figure 1, b is the working cylinder which is supplied with fluid from the
reservoir a. The connections and valve gear are not shown as they are of ordinary
construction. The piston rod b¹ is jointed to one arm of a bell crank lever c which
is pivotted at c¹ to the frame of the engine. The other arm of the bell crank
lever chas pivotted to it one end of the connecting rod d whose other end is
pivotted by the pin to the disc fly wheel e The pin d¹ passes through the fly
wheel and enters a slot fi at the end of the lever whose other end is pivotted
at f¹¹ to the frame of the engine. The lever ƒ has pivotted to it one end of a rod g
whose other end is pivotted to one arm of a bell crank lever h pivotted to the
frame of the engine at h¹. The other arm of the lever h supports a heavy
weighted lever i which is pivotted to the frame of the engine at i¹. The weighted
lever i presses upon one arm of the bell-crank lever ; which is pivotted at to the

rod k through which the coupled driving wheels . l. are propelled.
In Figure 2 are the other two driving wheels on the opposite side of the
engine. The axle of the leading wheel has upon it an eccentric m which carries
a pin m¹ entering a slot in a rod n pivotted to the frame of the engine at n¹.
o is a rod one end of which is pivotted to the rod n and the other to a rocking
lever p one end of which is pivotted at p¹ to the frame of the engine the other end
being provided with a pin p which runs in a slot at one end of the lever q whose
other end is pivotted at ql to the frame of the engine. The lever q is connected by
the rod to one arm of the bell crank lever 8 which is pivotted to the frame at s¹.
The other arm of the lever s supports the heavy weighted levert which is pivotted
to the frame of the engine at t¹. The levert presses upon the one arm of the bell
crank lever u pivotted to the frame at u¹. The other arm of the lever u has
pivotted to it the connecting rod by which the pump vis actuated by which the
fluid from the working cylinder b is returned to the reservoir a. The valves and
connections are of ordinary construction and therefore are not shown.
reservoir of fluid for supplying loss and x is an air valve to admit of a certain
quantity of air being pumped in with the fluid. y is a hand pump by which the
pressure can be got up in the reservoir a to start the engine.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would remark that
I am aware many attempts have before been made to obtain " perpetual motion " or
motive power without the expenditure of force but prior to my invention all these
attempts have been abortive and unsuccessful I therefore declare that what
I claim is
First The construction of any apparatus by which motive power is obtained
without the expenditure of power.
Second-The combination of apparatus for obtaining motive power consisting of
a reservoir of fluid under pressure, an engine driven by the fluid and a pump for
returning the spent fluid into the reservoir substantially as described.
Third Apparatus for increasing the power obtained consisting of weighted
levers which give out their power at a point nearer to their fulcra than those at
which they receive it, substantially as described.
Fourth-The apparatus for obtaining motive power substantially as described.
