IMPROVEMENTS IN GAS REGULATORS
Year: 1884

page_text: I, JAMES KAY of 24 Bridge Street, Ramsbottom, in the County of Lancaster,
Gas Rate Collector, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN GAS REGULATORS" to be as follows:-
This Invention has for its object the construction of gas regulators in which a
flexible diaphragm is used, in such a manner as to prevent the perforation of the
said diaphragm either by accident or design, and so preserve the instrument from
becoming useless and dangerous.
The Invention though not confined to, is specially applicable to regulators made
in two principal parts with flanges, and having a flexible diaphragm placed between,
so as to separate the lower from the upper part. In the lower part is formed the
inlet, and above it is the valve seat in which works a conical valve suspended by a
rod or spindle attached to the diaphragm. In the upper portion of the lower part
is situated the outlet. The vertical spindle is prolonged sufficiently to enter a
weight-box, or chamber, formed in the top of the upper part of the regulator and
round which the weights by which the pressure of the gas is regulated is placed,
the box or chamber having a cover with a small hole in it by which the instrument
is subjected to atmospheric pressure.
The Invention consists in casting with, or otherwise fastening to the upper part
of the regulator, between it and the weight box, a metallic guard plate or disc
having in its centre a hole large enough only to admit of the rod or spindle rising
and falling through it freely, and the attachment of a metallic guard plate or disc
of nearly the same diameter as the weight box to that part of the rod or spindle
which enters the said box. This latter disc serves not only as an additional guard
for the preservation of the flexible diaphragm from injury, but as a support for the
weights necessary for regulation. By the use of these two guards made and placod
in the manner described, perfect protection to the diaphragm is ensured.
Dated this Second day of February 1884.

page_text: I, JAMES KAY of 24 Bridge Street, Ramsbottom in the County of Lancaster,
Gas Rate Collector, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN GAS REGULATORS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawing, and to the letters
and figures marked thereon:-
This Invention has for its object the construction of gas regulators, in which a
flexible diaphragm is used, in such a manner as to prevent the perforation of the
said diaphragm either by accident or design, and so preserve the instrument from
becoming useless and dangerous.
The Invention though not confined to is especially applicable to regulators made
in two principal parts A and B, with flanges C, and having a flexible diaphragm D
placed between so as to separate the lower from the upper part. In the lower
part is formed the inlet E, and above it is the valve seat F, in which works a
conical valve G suspended by a rod or spindle H attached to the diaphragm D.
In the upper portion of the lower part is situated the outlet I.-The vertical
spindle is prolonged sufficiently to enter a weight box, or chamber J, formed in
the upper part of the regulator, and round which the weights, by which the
pressure of the gas is regulated are placed, the box or chamber having a cover K,
with a small hole L in it by which the instrument is subjected to atmospheric
pressure.
The Invention consists in casting with, or otherwise fastening to the upper
part A of the regulator, between it and the weight box, a metallic guard plate or
disc M, having in its centre a hole large enough only to admit of the rod or spindlo
rising and falling through it freely, and the attachment of a metallic guard plate,
or disc N. of nearly the same diameter as the weight box, to that part of the rod
or spindle which enters the said box. This latter disc N serves not only as an
additional guard for the preservation of the flexible diaphragm D from injury, but
as a support for the weights necessary for regulation. By the use of these two
guards M and N made and placed in the manner described perfect protection to
the diaphragm is ensured.
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
The construction of gas regulators with a guard plate M, cast or otherwise fixed
to the case, and a guard plate N attached to the spindle, both guards being arranged
as herein described and shown on the Drawing.
