I, GEORGE GREEN of N° 180 Rhodeswell Road, Limehouse, London, E. in the
County of Middlesex Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN GAS MOTOR ENGINES, AND IN THE MEANS, OR METHOD OF
SUPPLYING THEM WITH GAS to be as follows:-
I use Cylindrical, or Spherical Vessels, or Holders, for the purpose of containing
highly compressed Gas, from which Vessels, or Holders, the Gas is conveyed to the
Engine in any suitable way. I connect with the Engine, so as to be worked by
it, a Pump for compressing the Gas into the above mentioned Vessels, or Holders,
which Pump may be also worked by Manual power,

1, GEORGE GREEN, of 180 Rhodeswell Road, Limehouse, London E, in the
County of Middlesex, Engineer do hereby declare the nature of my invention for
"IMPROVEMENTS IN GAS MOTOR ENGINES, & IN THE MEANS, OR METHOD OF
SUPPLYING THEM WITH GAS" and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :—
I construct a cylindrical, or other suitably shaped reservoir (by preference of
copper) into which I compress the gas until it obtains a high pressure (of say
120 lbs pr superficial square inch). I connect with this reservoir a pressure guage
for the purpose of indicating at all times, the pressure of the gas in this reservoir.
I then, by ineans of a pipe connected with this reservoir, and fitted with a cock, or
stop valve, allow a portion of the compressed gas to pass into another vessel, or
reservoir, made after the manner of a blacksmiths Circular Bellows, the top of which
rises or falls according to the quantity of gas contained in it & required to work
the Engine. On the top of this vessel I fit a Safety Valve weighted, or pressed
upon with a pressure sufficient to work the Engine. In the pipe connecting the
two reservoirs I fit an easily moved second cock, or an ordinary "Throttle Vulve,"
which is acted upon by the rising or falling of the top of this second reservoir, by
connecting the lever, on the plug of the cock, or on the spindle of the "Throttle
Valve," in any convenient way, so that the rising of the top of the said vessel, or
reservoir, partly, or wholly shuts off the supply of gas from the main reservoir,
& the falling of it opens the cock, or valvo, & allows more gas to enter, sufficient
for working the Engine.
My improvement of a Gas Motor Engine consists in adding to, & connecting with
it, an ordinary gas compressing pump for supplying compressed gas to the main,
or high pressure reservoir, when a further supply of gas is required: This pump
may, by means of a flexible Hose pipe, be connected with any source of gas supply,
& worked until a sufficient quantity of Gas is supplied to the reservoir.
Having now particularly described & ascertained the nature of my said
Invention, & in what manner the same is to bo performed, I declare that what
I claim is
1st The using of highly compressed gas in the manner substantially as described,
for working Gas Motor Engines. I do not claim the using of it for any other
purpose.
2nd The addition of a gas compressing pump to the Engine, for supplying the
high pressure gas reservoir with gas, substantially as described. I do not claim
the use of it for any other purpose.
