PROVISIONAL SPECIFICATION.
Improvements in or connected with Gas Governors.
I, RICHARD SIMON, of The Trent Gas Engine Company, Limited, Duke Street,
New Basford, Nottingham, Engineer, do hereby declare the nature of this invention
to be as follows:-
-
This invention has for object governing or regulating the flow of gas from a
supply to the point of combustion.
The invention is specially applicable for use with bags of gas engines, also with
heating and other stoves and lighting apparatus.
I attach to the nozzle of a bag, a box containing a valve and a diaphragm, both
of which are connected to a rod, whose upper end has outside the box, an annular
grooved collar screwed thereon for adjustment.
Short ends of levers are arranged in the groove of the collar and the long ends
bear against the bag, so that any sudden impulse or fluctuations of pressure will be
instantly governed without affecting the pressure in the pipes.

COMPLETE SPECIFICATION.
Improvements in or connected with Gas Governors.
I, RICHARD SIMON, of The Trent Gas Engine Company, Limited, Duke Street,
New Basford, Nottingham, 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 :-
This invention has for object, governing or regulating the flow of gas from a
supply to the point of combustion.
The invention is specially applicable for use with bags of gas engines, also with
heating and other stoves and lighting apparatus.
I attach to the nozzle of a bag, a box containing a valve and a diaphragm, both
of which are connected to a rod, whose upper end has outside the box, an annular
grooved collar screwed thereon for adjustment. Short ends of levers are arranged
in the groove of the collar, and the long ends bear against the bag, so that any
sudden impulse or fluctuations of pressure will be instantly governed without
affecting the pressure in the pipes.
Figure 1 of the annexed drawings is a vertical section of an apparatus as adapted
for use with gas engines. A is a metal box having inlet B, and outlet C, and
furnished with a slack vibrating membrane D, preferably of leather, in which the
spindle E of the valve F is fixed gas tight.
On the upper part of the spindle E is the adjustable guide G in a groove on
which run the ends of one or more long levers H, the other ends of which are in
contact with the sides of a rubber gas bag or holder K. The gas entering K
through B and C at pressure, dilates the bag, whereupon the expanding sides press
the long arms of the levers H outwards, thereby closing (more or less completely
according to the position of the guide G which may be regulated at will) the valve F
thus cutting off or diminishing the further supply of gas to K until the pressure
therein has fallen to the degree of pressure desired.
The gas engine, or other machine thus takes its feed from the gas stored in the
Price dl

page_text: bag K without affecting the pressure in the pipes and conversely the pressure in
the pipes cannot fill the bag K with gas at the same, pressure.
Figure 2 is a vertical transverse section of a gas regulator or governor with two
leather, or other flexible diaphragms, and having the same action as the governor
already described, the gas bag being dispensed with.
Figure 3 is an end elevation of that.shown at Figure 2.
In this apparatus, the inflowing gas from B has free play in the lower chamber A
and passes through valve F in port L and also into chamber M where it acts on
the diaphragm D and depresses it, causing the valve F to close by pressing on
spindle E. By adjusting the weight H on the threaded rod N, the degree of
opening of the valve F and the quantity of gas passing from A through the
outlet can be regulated to the greatest nicety and all fluctuations of pressure of
the main are compensated for, the diaphragms thereby obviating the jumping of the
lights.
The invention also diminishes and regulates the pressure in the supply pipes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In a gas engine gas supply, the apparatus shown a Figure 1, whereby the
valve F is opened and closed by levers H, H, bearing against the gas bag in the
manner and for the purposes set forth.
2. The double chambered apparatus shown at Figure 2, whereby gas pressure
equilibrates two diaphragms, one diaphragm being in the upper chamber, and the
other within the valve box, the degree of the valve's opening being adjustable for
a fixed consumption by an adjustable weight and rod, as described.
