Improvements in Apparatus for Deriving, Controlling, and Regu-
lating Motive Power from Gas or Oil Engines for various
purposes.
I, THOMAS THOMSON, of Westlea, Barrhead, in the County of Renfrew, North
Britain, Manufacturer, do hereby declare the nature of this invention to be as
follows, that is to say:-
My said Invention has for its object the deriving, controlling, and regulating
of motive power from gas or oil engines in a better and more advantageous manner
than is done with arrangements hitherto in use. My improved apparatus is
applicable to wheeled vehicles, to boats and ships, and for stationary or non-
locomotive purposes.
My Invention consists mainly in applying the power of a gas or oil engine by
means of pumping apparatus to compress air into a receiver or accumulator, and
in employing the compressed air to work a fluid-pressure motor of any suitable
kind such for example as one constructed and operating like a steam engine.
My Invention also com-rises devices, hereinafter described, and to be employed in
carrying out the improvements.
The air pumping or compressing apparatus is constructed so as by a water
jacket on the pumping cylinder or cylinders or in an equivalent manner to cool the
air whilst or on being compressed in order to economise the compressing power.
The receiver for the compressed air may be a vessel of any suitable and convenient
construction or form. It may for example, consist of tubing or hollow parts
which may also constitute more or less of the framing of the apparatus. Before
entering the air engine or motor the compressed air is passed through a heater of
tubular or other suitable kind, the heating agent being the hot exhaust gases from
the gas or oil motor; and the same hot gases or a portion of them may be led
through a jacket on the air-engine cylinder or cylinders to supply heat to the
air expanding therein.
The water which is used in a jacket to prevent overheating of the cylinder
of the gas or oil motor, may on becoming heated be made to assist the heating of
the compressed air prior to its operating in the air engine. The exhaust air from
the air engine may if colder than the atmosphere be advantageously led to the air
compressing apparatus.
The exhaust gases from the gas or oil motor may be passed through and agitated
in an alkaline or other solution to remove objectionable constituents prior to
their final discharge.
The air engine can be controlled and regulated and its action and speed modified
like an ordinary steam engine, more conveniently and quickly than can be done
with a directly acting gas or oil motor.

Improvements in Apparatus for Deriving, Controlling, and Regu-
lating Motive Power from Gas or Oil Engines for various
purposes.
N
I, THOMAS THOMSON, of Westlea, Barrhead, in the County of Revfrew, North
Pritain, Manufacturer, 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, that is to say:-
My said Invention has for its object the deriving, controlling, and regulating
of motive power from gas or oil engines in a better and more advantageous manner
than is done with arrangements hitherto in use. My improved apparatus is
applicable to wheeled vehicles, to boats and ships, and for stationary or non-
locomotive purposes.
My Invention consists mainly in applying the power of a gas or oil engine by
means of pumping apparatus to compress air into a receiver or accumulator, and
in employing the compressed air to work a fluid-pressure motor of any suitable
kind such for example as one constructed and operating like a steam engine.
My Invention also comprises devices, hcrcinafter described, and to be employed in
carrying out the improvements.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append an explanatory drawing, to be
hereinafter referred to, and showing in plan part of my improved apparatus, as
made according to one modification. In this drawing the same reference letters
are used to mark the same or like parts wherever they are repeated.
The air-pumping. or compressing apparatus, is constructed so as by a water
jacket on the pumping cylinder (or it might be cylinders) A, or in an equivalent
manner to cool the air whilst or on being compressed in order to economise the
compressing power. The receiver, B, for the compressed air may be a vessel of
any suitable and convenient construction or form. It may, for example, consist
of tubing or hollow parts which may also constitute more or less of the framing
of the apparatus. The compressed air is led to the receiver, B, by a pipe, C.
The pumping apparatus is driven by a crank disk, D, operated through spur
wheels, E, from the oil or gas engine crank shaft, G. The compressed air before
entering the air engine or motor, H, (which it does by a pipe R) is passed through
a heater, J, of a tubular or other suitable kind (to which is led by a pipe, S) the
heating agent being the hot exhaust gases from the gas or oil motor, F, which are
led to the heater from the motor by a pipe, K, and the same hot gases or a portion
of them are led by a pipe, L, through a jacket on the air-engine cylinder or cylin-
ders, H, to supply heat to the air expanding therein. These same gases are led
from the jacket of the air-engine cylinder, H, by a pipe, M, to a vessel, N, con-
taining an alkaline or other solution in which they are agitated to remove object-
tionable constitutents prior to their final discharge to the atmosphere.
The water which is used in a jacket to prevent overheating of the cylinder of the
gas or oil motor, H, may on becoming heated be made to assist the heating of
the compressed air prior to its operating in the air engine. The exhaust air from the
air engine, H, may if colder than the atmosphere be advantageously led by
the pipe, T to the air-compressing apparatus.
The air engine, A, acts on a crank shaft P', in an ordinary way, and the driving
wheels, Q, of the vehicle are applied to it; or motion may be derived from the
crank shaft in any suitable manner applicable to the propulsion of boats or ships
or for other purposés.

page_text: The air engine can be controlled and regulated, and its action and speed modi-
fied like an ordinary steam engine, more conveniently and quickly than can be
done with a directly-acting gas or oil motor.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination and arrangement of parts constituting the improved appa-
ratus for deriving, controlling, and regulating motive power from gas or oil
engines for various purposes substantially as herein before described.
2. Applying the power of a gas or oil engine by means of pumping apparatus to
compress air into a receiver or accumulator and employing the compressed air to
work a fluid-pressure motor from which power may be derived for the propulsion
of vehicles, boats, or ships, or for other purposes substantially as hereinbefore
described.
