I, ALFRED CHRISTOPHER TOBLER of 12 Rue de la Bourse, in the City of Paris
in the Republic of France, Manufacturer of Gas Regulators do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in gas regulators and has for its object
the construction of such a device in a very simple manner, which shall be
hermetically closed and shall operate with accuracy.
This apparatus is principally characterized by the disposition of conical clack
valves ground in place embodied with the stem in combination with a metal bell, of
which the sides are conveniently folded over themselves, or furnished with a
shoulder of metal or any other convenient material such as gutta-percha, in such a
manner as to increase its buoyancy and render its action more sensitive.
"
The body of the regulator is furnished with orifices for the entry and exit of the
gas; means are provided in the lower part for the withdrawal of any liquid that
may be condensed and collected in the device.
Within the body is arranged tallic bell preferably of aluminium, the lower
edge of which is turned up, so as to form a trough, or is furnished with a shoulder
or is thickened up, the said lower edge being immersed in a bath of mercury,
contained in an annular channel arranged in the body of the device. Within the
chamber a casting is supported into which is screwed a sleeve with orifices arranged.
therethrough, and adapted to form seats for the valves.
The valves are mounted upon a stem to which is attached the bell. The upper
part of the stem is furnished with a shoulder, on which rests a series of metal
washers or weights, and the upper end of the stem is in contact with a spring,
lodged in the socket of a manometer, mounted on the hood of the casing.
A disc, pierced with a central hole for the passage of the valve stem and the gas,.
is disposed in the bell, and is fixed on the circular part of the casing which forms
the trough for the mercury. A cover is also provided to close in the upper part of
the body of the device.
When the gas enters the apparatus it tends to lift the bell, the stem and the
valves; which movement closes the valves, and prevents the excess of supply of
gas being communicated to the bell and further the action of the washers or
weights will produce a downward pressure, more or less in amount, for the,
automatic regulation of the amount consumed.
During the upward movement of the bell and the valves, the end of the stem
compresses the spring of the manometer, which will in turn operate: the indicating
needle.

page_text: I ALFRED CHRISTOPHER TOBLER of 12 Rue de la Bourse in the City of Paris
in the Republic of France Manufacturer of Gas Regulators 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 relates to improvements in gas regulators and has for its object
the construction of such a device in a very simple manner, which shall be
hermetically closed, and shall operate with accuracy.
This apparatus is principally characterised by the disposition of conical clack
valves ground in place embodied with the stem in combination with a metal bell of
which the sides are conveniently folded over themselves or furnished with a
shoulder of metal or of any other convenient material such as gutta percha in such
a manner as to increase its buoyancy and render its action more sensitive.
In order that my invention may be the better understood I will now proceed to
describe it in relation to the accompanying drawing hereunto annexed reference
being had to the letters and figures marked thereon; like letters refer to like parts
in the various figures.
Fig. 1. is a vertical section of a gas regulator according to my invention.
Fig. 2 is a vertical section of the bell mounted upon the valve spindle.
Figs. 3 and 4 shows two modified constructions of the bell in which the bent up
sides are substituted by a shoulder or rim of metal or india rubber.
The body a of the regulator is furnished with orifices b, c, d, for the entry and
exit of the gas.
When the regulator is placed above or upon the side of the
meter one or other of the inlet orifices b or c is closed by a screw plug e.
Means f. are provided in the lower part of the casing for the withdrawal of liquid
that may be condensed and collected in the device.
Within the body is arranged a metallic bell g preferably of aluminium the lower
edge of which is turned up so as to form a trough or is furnished with a shoulder
or is thickened up, the said lower edge being immersed in a bath of mercury
contained in an annular channel h arranged in the body of the device. Within the
chamber a a casting i is supported into which is screwed a stem k, with orifices
arranged therethrough and adapted to form seats for the valves m.
The valves m are conical and are ground on their seats and are mounted upon a
stem n to which is attached the bell g by means of the nut o.
The upper part of the stem n is furnished with a shoulder p on which rests
a series of metal washers or weights 9 and the upper end of the stem n is in
contact with a spring lodged in the socket r of a manometer s mounted on the hood
of the casing t.
A disc u pierced with a central hole v for the passage of the valve stem and the
gas is disposed in the bell and is fixed on the circular part n cf the casing which
forms the trough for the mercury. A cover x. is also provided to close in the
upper part of the body a of the device.
When the gas enters the apparatus it tends to lift the bell g, the stem n and the
valves m which movement closes the valves m and the orifices and prevents the
excess of supply of gas being communicated to the bell and further the action of
the washers or weights q will produce a downward pressure more or less in amount
for the automatic regulation of the amount consumed.
During the upward movement of the bell and the valves the end! of the stem "
compresses the spring of the manometer which will in turn operate the indicating
needle.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. In a gas regulating device, the arrangement of conical valves attached to a
stem and adapted to be ground upon their seats to produce bermetical closure,
substantially as described.
2nd. In a gas regulator, the arrangement of a bell of aluminium or other
suitable material having bent up edges, or being furnished with a shoulder in
order to increase the buoyancy of the bell and to make its action more sensitive.
3rd. In a gas regulator the combination of conical valves with a floating ball
substantially as described.
Dated this 1st day of September 1896.
