PROVISIONAL SPECIFICATION.
Improvements in Gas Governors, and Apparatus for Regulating the
Supply of Gas in connection therewith.
I, JOSHUA HORTON, of 29 Bourne Street, Dudley, in the County of Worcester,
Gas Governor Manufacturer, do hereby declare the nature of my invention for
IMPROVEMENTS IN GAS GOVERNORS AND APPARATUS FOR REGULATING THE
SUPPLY OF GAS IN CONNECTION THEREWITH to be as follows:-
To the outlet of the gas meter, or to the service pipe conveying the gas from the
meter to the burners, I fix a partition, in the centre of which is a valve and its
seating. The valve, which is perforated, is connected by a rod to an inverted cup,
which floats in an annular trough of mercury, and underneath which balance
weights are placed. The valve allows the gas to pass up a pipe underneath the
inverted cup, which rises or falls according to the pressure. The gas is prevented
from escaping round the inverted cup by means of the mercury.
Dated this 11th day of January 1894.

COMPLETE SPECIFICATION.
Improvements in Gas Governors, and Apparatus for Regulating the
Supply of Gas in connection therewith.
1, JOSHUA HORTON, of 29 Bourne Street, Dudley, in the County of Worcester,
Gas Governor 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 :-
To the outlet of the gas meter, or to the service pipe conveying the gas from the
meter to the burners, I fix a partition, in the centre of which is a valve and its
seating. The valve, which is perforated, is connected by a rod to an inverted cup,
which floats in an annular trough of mercury, and underneath which balance-
weights are placed. The valve allows the gas to pass up a pipe underneath the
inverted cup, which rises or falls according to the pressure. The gas is prevented
from escaping round the inverted cup by means of the mercury.
The gas is admitted by the inlet at the bottom of the governor up a short pipe
and through the perforated valve into a smaller pipe, which conveys the gas to the
small aperture, and underneath the inverted cup floating in an annular trough of
mercury which rises or falls according to the pressure, which pressure is regulated
by the balance-weights underneath the perforated valve. The valve is perforated
in order to keep a constant supply of gas underneath the inverted cup; and the pipe
after leaving the valve is to prevent the gas making its escape by the outlet before
entering the inverted cup. The gas passes over the top of the small pipe, and
down the sides into the lower chamber, from thence to the outlet and to the
burners.
Fig. 1 is a front elevation of my improved gas governor.
Fig. 2 is a plan of Fig. 1, shewing the annular trough.
Fig. 3 is a section of Fig. 1, shewing the perforated valve with balance-weights
underneath.
Fig. 4 is a section of Fig. 1, shewing the valve seating and pipes before and
after leaving the valve.

page_text: A A A is the outer case, which may be made of cast-iron, zinc, brass or any
other suitable metal, B is the inlet to pipe CC, and to the perforated valve dd,
which is connected to the inverted cup G G, by a rod passing through the small
aperture ff, which also acts as a guide for the valve, H H is the annular trough
filled with mercury, E E is the pipe conveying the gia from the valve to the
sinall aperture and underneath the inverted cup, J J is the space outside the pipe
leading to the bottom chamber K K, and to the outlet L, 66 is the valve seating
and ee are the balance-weights underneath the valve.
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. Improvements in gas governors substantially, as hereinbefore described, and
illustrated on the accompanying drawing.
2. In bringing the annular trough low down into the lower chamber.
3. In placing the balance-weights underneath the valve.
4. In using a perforated valve.
5. In passing the gas up a small pipe after leaving the valve.
