Improvements in and connected with Fluid Pressure Apparatus
for Generating, Storing, and Transmitting Power.
I, CHARLES M. JOHNSON, of Broad Street House, Old Broad Street, in the City of
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to improvements in and connected with motors primarily
driven by an explosive charge of air and gas or oil spirit or the like, whereby the
vibration usually inherent to motors of this class is practically obviated, and
whereby a smaller motor may be made capable of giving off more power for a short
time than is possible with an engine as usually constructed.
According to my invention I construct a motor to be driven by an explosive such
as a mixture of air and gas or oil, spirit or the like. I arrange in connection with
this explosion motor an air pump compressor which operates at each acting stroke
of the explosion motor. The air from this pump is forced into a reservoir or tank
and the compressed air therein is utilized to drive a simple or compound air motor
of any suitable construction. The water or other suitable liquid or fluid used to
cool the cylinder or cylinders of the explosion motor is contained in a jacket round
said cylinder or cylinders and there is or are connections from that jacket or those
jackets to a jacket or jackets round the cylinder or cylinders of the air motor in
such manner as to permit of a constant circulation of the cooling water. As the air
expands in the cylinder or cylinders of the air motor owing to the cut off being
arranged to operate comparatively early during each stroke the air in said cylinder
or cylinders is greatly lowered in temperature and consequently the cylinders are
also kept cool and serve to cool the water in their jackets, the effect of which will be
that the same water will also serve to cool the cylinder or cylinders of the explosion
motor, whereby it will only be necessary to carry a very small quantity compara-
tively of cooling fluid.

page_text: London, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention relates to improvements in and connected with motors primarily
driven by an explosive charge of air and gas or oil, spirit or the like, whereby the
vibration usually inherent to motors of this class is practically obviated, and
whereby a smaller motor may be made capable of giving off more power for a short
time than is possible with an engine as usually constructed.
Figure 1 of the accompanying sheet of drawings represents diagrammatically in
plan a wheeled vehicle provided with motive power apparatus, constructed accord-
ing to my invention and
Figure 2 is a transverse sectional diagrammatic view of a modification.
As shewn on the drawing I construct a motor with say two cylinders A A driven
by an explosive such as a mixture of air and gas or oil, spirit or the like and I
arrange in connection with this explosion motor an air or other fluid pump com-
pressor C which operates at each acting stroke of the explosion motor. The air
from this pump is forced into a tubular or other reservoir or tank B and the
compressed air therein is utilised to drive a simple air motor having cylinders DD;
or any other suitable construction of simple or compound air motor
may be employed, the air being conducted to the cylinders by means
of a pipe B valve B3 and branches B and B5.
The exhaust passes away
by the exhaust pipe D³. The water or other suitable liquid or fluid used to cool the
cylinder or cylinders of the explosion motor A is contained in a tank I and by
means of a pipe I¹ passes to the jacket A¹ around one of the cylinders of the explo-
sion motor thence to the jacket A2 of the compressor C, thence to jacket A³ of the 2
other explosion motor cylinder A and there is a connection or pipe I² from the
jacket A³ to the jacket D¹ which surrounds the cylinders D D of the air motor. The
water then passes by the pipe I³ back to the tank I so as to permit of a constant
circulation of the cooling water. As the air expands in the cylinder or cylinders
of the air motor owing to the cut off being arranged to operate comparatively
early during each stroke the air in said cylinder or cylinders is greatly lowered in
temperature and consequently the cylinders are kept comparatively cool and serve
to cool the water, the effect of which will be that the same water will also serve to
cool the cylinder or cylinders of the explosion motor whereby it will only be
necessary to carry a comparatively very small quantity of cooling fluid. Indeed if
the jacket 1 surrounding the cylinders of the air engine be made larger than is
usually the case the separate water tank I may be dispensed with altogether. This
construction is shown in Figure 2 in which the cylinders A. A of the explosion
motor and the compressor cylinder C are enclosed in a water jacket A', which by
a pipe I receives cooled water from the tank-like jacket D¹ surrounding the
cylinders 1 D of the air engine which water when heated by passing round the
cylinders in the jacket A¹ again passes off by the pipe I2 to the tank-like jacket I).
If desired the air in the cylinders D) of the air motor may be further utilized when
it passes out by the exhaust pipe 12 by lengthening the latter at 13 as shewn in
Fig. 1 and passing the exhaust air through a coil D in the water tank I, and into
the outer air by the pipe D5 the effect of which will be to still further cool the water
contained in said tank. Or there may be a coil D of the same kind in the tank
like jacket D, Figure 2.
It is evident that instead of the cooling water passing from the jacket of one
cylinder of the explosive motor to the jacket of the other cylinder, there may be a
branch pipe from the water supply pipe I' to the jacket of the second so that the
water arrives at the second jacket at the same temperature as it arrives at that of the
first and similarly the water from each jacket of the explosion motor cylinders may
by suitable connections be conducted to the jacket or jackets of the air motor
cylinders so that the second jacket thereof shall receive water as warm as that
supplied to the first.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In combination with the method of generating storing and transmitting
power consisting in the utilisation of an cil or explosive engine, to operate a pump
or compressor to fill a reservoir with air or other fluid under pressure, which air is
used to drive an engine from which the power is taken off, the utilisation of the
heat of the cooling water proceeding from the jacket of the oil engine to heat and
expand the air used to drive the engine from which the power is taken off sub-
stantially as described.
2. In combination with the method of generating storing and transmitting power
consisting in the utilisation of an oil or explosive engine to operate a pump or com-
pressor to fill a reservoir with air or other fluid under pressure, which air is used to
drive an engine from which the power is taken off, the utilisation of the heat of the
cooling water proceeding from the jacket of the oil engine to heat and expand the
air used to drive the engine from which the power is taken off and the utilisation
of the cold produced by the expansion of the air in the cylinders of the engine last
referred to to lower the temperature of the cooling water substantially as described.
3. The constructions of apparatus shown on the drawing.
