PROVISIONAL SPECIFICATION.
An Improved Gas Regulator.
I, JOHN TAYLOR of the Firm of John Taylor and Sons, Queens Road Nottingham,
Engineer do hereby declare the nature of this invention to be as follows:-
-
This Invention has for its object improvements in gas regulators or gas bags
for gas engines and other purposes; so as to maintain one uniform pressure therein;
and to automatically control the supply of gas thereto.
For this purpose, I have a cylindrical or other shaped dished casting; having one
suitable inlet branch or opening; and one outlet branch, in the circumference of
same. The open side of this dished casting is completely covered with a thin india
rubber diaphragm, capable of being distended; and secured to the casting by a
junction ring, bolts and nuts or other suitable means; so as to form a gas tight
joint with the cylindrical casting.
The inlet branch-formed in the upper side of this dished casting-is bored out
to form a seating for, and is fitted with, a suitable valve; capable of being raised from
its seating by the short cam-shaped end of a double ended lever, working underneath
the valve in a joint or fulcrum from the dished casting. The opposite longer end of
this lover, is attached to the india rubber diaphragm by a bolt, nut and washers;
or other suitable means.
The action of this lever is such, that when the india rubber diaphragm is not
distended, the lever is in a perpendicular position; and the full part of the cam end,
raises the regulating valve wide open to admit gas thereby into the gas regulator or
bag; and that when the quantity and pressure of gas in the regulator is such, that,
the diaphragm is distended, it carries with it the long end of the lever, moving it
out of the perpendicular; and thereby carries the full part of the cam away from the
valve; either to allow same to come down to its seating, and cut off the supply
of the incoming gas to the regulator; or to so automatically control the supply of
gas thereto, as to maintain a quantity of gas at a uniform pressure therein;
according as the gas is withdrawn therefrom by the outlet branch in varying or
constant quantities; or intermittent or regular periods.
The extent to which the india rubbor diaphragm is distended, and the lever
carried out of the perpendicular, directly controls the extent to which the admission
valve is opened.

'An Improved Gas Regulator.
1, JOHN TAYLOB of the Firm of John Taylor and Sons, Queen's Road, 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 its object improvements in gas regulators or gas bags for
gas engines and other purposes, so as to maintain one uniform pressure therein, and
to automatically control the supply of gas thereto.
For this purpose I have a cylindrical or other shaped dished casting, having one
suitable inlet branch or opening; and one outlet branch in the circumference of the
The open side of this dished casting is completely covered with a thin
same.

page_text: india-rubber diaphragm, capable of being distended, and secured to the casting by a
junction ring, bolts and nuts, or other suitable means; so as to form a gas tight joint
with the cylindrical casting.
The inlet branch formed in the upper side of this dished casting is bored out to
form a seating for, and is fitted with a suitable valve, capable of being raised from
its scating by the short cam-shaped end of a double ended lever, working underneath
the valve in a joint or fulcrum from the dished casting.
.
The opposite longer end of this lever is attached to the india-rubber 'diaphragm.by
a bolt, nut and washers, or other suitable means.
.
The action of this lever is such, that when the india-rubber diaphragm is "not
distended, the lever is in a perpendicular position; and the full part of the cam end
raises the regulating valve wide open to admit gas thereby into the gas regulator or
bag and that when the quantity and pressure of gas in the regulator is such, that
the diaphragm is distended, it carries with it the long end of the lever, moving it out
of the perpendicular; and thereby carries the full part of the cam away from the
valve, either to allow same to come down to its seating and cut, off the supply of the
incoming gas to the regulator; or to so automatically control the supply of gas thereto,
as to maintain a quantity of gas at a uniform pressure therein; according as the
gas is withdrawn therefrom by the outlet branch in varying or constant quantities;
or intermittent or regular periods.
The extent to which the india-rubber is distended, and the lever carried out of the
perpendicular, controls the extent to which the admission valve is opened.
And in order that my Invention may be fully understood, and more readily carried
out and into effect, I will proceed to describe the accompanying sheet of drawings,
reference being had to the letters marked thereon.
Fig. 1, is a front elevation of my improved gas regulator, with a portion of the
india-rubber diaphragm removed to shew the lever &c.
Fig. 2 is a plan of the same.
Fig. 3 is a longitudinal sectional side elevation of the same.
Similar letters refer to similar parts throughout the several views.
In my improved gas regulator, I have a cylindrical or other shaped dished
casting A, having a suitable inlet branch or opening M, and an outlet branch K in
the circumference of the same. The open side of this dished casting is completely
covered with a thin india-rubber diaphragm C, capable of being distended; and
secured to the casting A, by a junction ring B, bolts and nuts P. P; or other
suitable means, so as to form a gas tight joint with the cylindrical casting A.
The inlet branch M formed in the upper side of this dished casting A, is bored out
to form a seating for, and is fitted with a suitable valve D; capable of being raised
from its seating by the short cam-shaped end E of a double ended lever E, working
underneath the valve D in a joint or fulcrum R from the dished casting A.
The
opposite longer end of this lever E, is attached to the india-rubber diaphragm C by
a bolt and nut F, and washers H, H, or other suitable means.
The action of this lever E is such, that when the india-rubber diaphragm Cis
not distended, the lever E is in a perpendicular position, shewn at T in dotted
lines Fig. 3; and the full part of the cam end E, raises the regulating valve D
wide open, to admit gas thereby into the gas regulator.or bag A: C; and that when
the quantity and pressure of gas in the regulator A. C, is such that the diaphragm C
is distended, it carries with it the long end of the lever E, moving it out of the
perpendicular, and thereby carries the full part of the cam E, away from the valve D,
either to allow same to come down to its seating, and cut off the supply of the
incoming gas to the regulator A. C, or to so automatically control the supply of, gas
thereto, as to maintain a quantity of gas at a uniform pressure therein; according
as the gas is withdrawn therefrom through the outlet branch K in varying or con-
stant quantities; or intermittent or regular periods. The extent to which the india-
rubber diaphragm C is distended, and the lever E carried out of the perpendicular-
controls the extent to which the admission valve D is opened.

page_text: Having now particularly explained and ascertained the nature and action of my
said invention, I declare what I claim is :-
1. Gas regulators to which the supply of gas is directly controlled by an
admission valve opened and closed from a flexible diaphragm on the regulator, by
means of a short cam shaped or inclined end of a double-ended lever, acting on the
underneath of the said admission valve. The lever having its fulcrum on the regulator
casing, and its longer end attached to the diaphragm; substantially in the manner
and for the purposes herein shown and described.
2. Gas regulators substantially as described and shewn in Figs. 1, 2 and 3 of the
accompanying drawings.
