IMPROVEMENTS
This Invention relates especially to that class of gas regulator in which a
diaphragm is used as the controlling medium, and has for its object a more perfect
system of connecting the casing of the gas regulator with the meter or gas supply
pipe, whereby injury to the gas regulator is obviated.
In carrying out my Invention instead of having a tail piece to be soldered to
the meter connection or gas pipe as heretofore I arrange a branch to project from
the outer casing and form a screw thread at its extremity which is capable of
either screwing direct into the meter or gas pipe, or such screw threaded may fit
an ordinary union joint, and thus I am enabled to effect the connection of the
regulator with the use of heat, which tends to injure the diaphragm and other.
internal parts of gas regulators.

HENRY DEVINE, of Manchester, in the County of Lancaster. "IMPROVEMENTS
IN THE CONSTRUCTION OF GAS REGULATORS."
This Invention relates especially to that class of gas regulator in which a
diaphragm is used as the controlling medium, and has for its object a more perfect
system of connecting the casing of the gas regulator with the meter or gas supply
pipe, whereby injury to the gas regulator is obviated.
In carrying out my Invention instead of having a tail piece to be soldered to
the meter connection or gas pipe as heretofore I arrange a branch to project from
the outer casing and form a screw thread at its extremity which is capable of either
screwing direct into the meter or gas pipe, or such screw thread may fit an ordinary
union joint, and thus I am enabled to effect the connection of the gas regulator
without the use of heat, which tends to injure the diaphragm and other internal
parts of gas regulators.
And in order that this my said Invention may be the more readily understood
and carried into practical effect, I have hereunto annexed a Drawing illustrative of
my improved gas regulator, and will now proceed to describe the same by the
assistance of the letters of referance marked on the several parts.
A is the outer casing formed in two parts, as illustrated, and supporting between
them the specially prepared leather diaphragm B. The spindle C of this diaphragm
is provided with a valve at its lower extremity, and which closes the inlet passage
in the ordinary manner. D is the branch pipe for connecting the regulator to the
gas meter, and which is effected by either screwing such branch D direct into the
meter or by connecting the tail piece E to the meter; F is the branch, and G the
tail piece of the union joint for connecting my improved gas regulator to the gas
supply pipe. It will thus be evident that this improved construction of gas
regulator can be fixed without heat being imparted to it as heretofore, and hence
that the diaphragm is prevented being injured. In some cases I obtain a similar
effect by prolonging the branches D and F, in which cases the union joints are
dispensed with.
My Invention further relates to a novel method of exercising pressure upon the
upper side of the diaphragm B according to the number of gas lights requiring to
be regulated, and consists in the use and application of a screwed cap H provided
on the inside with a suitable guide piece I to receive a spiral spring J, which is
inserted between such guide piece I and a shoulder K formed upon the diaphragın
spindle C, and so that by screwing or unscrewing such cap more or less a corre-
spondingly greater or less pressure is exercised upon the diaphragm, and whereby
weights are dispensed with.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods with which I am acquainted for carrying.
the same into practical effect, I wish it to be understood that I claim,-
The improvements in gas regulators, substantially as herein before described and
illustrated on the accompanying Drawing.
In witness whereof, I, the said Henry Devine, have hereunto set my hand
and seal, this First day of June, in the year of our Lord One thousand
eight hundred and eighty one.
