Gas Engineer. "IMPROVEMENTS IN APPARATUS FOR CONTROLLING AND REGULATING
THE FLOW OR PASSAGE OF GAS, AND OTHER FLUIDS; AND IN APPLIANCES
CONNECTED THEREWITH.
The object of this invention is to regulate and controll, (preferably at a distance)
the flow of gas and other fluids to gas and fluid meters and services; whereby
only a determinate or fixed amount of gas or other fluid is allowed to pass from
the principal main or supply pipe to the meter or service.

the screw box described a necked stud is situated, and attached to this stud, a
wire, chain or cord communicates to and operates the main tap, which regulates
the flow of gas or other fluid from the main supply to the meter or service.

its summit, a traversing backward, and forward movement, is given to the screw
box carrying the index finger or pointer, and thereby points and indicates upon a
graduated plate, or dial, the exact amount of gas, that should be allowed to pass
from the main supply pipe to the meter or service.

GEORGE PHILIPPE LEMPRIÈRE of Balsall Heath in the County of Worcester, Gas
Engineer. IMPROVEMENTS IN APPARATUS FOR CONTROLLING AND REGULATING THE
FLOW OR PASSAGE OF GAS AND OTHER FLUIDS, AND IN APPLIANCES CONNECTED
THEREWITH
The object of my Invention is to regulate and control (preferably at a distance)
the flow of gas and other fluids to gas and fluid meters and services; whereby only
a determinate or fixed amount of gas or other fluid is allowed to pass from the
principal main or supply pipe to the meter or service.
By the means hereinafter described, a considerable amount of gas or other fluid
and economy incidental thereto, are thereby saved to the consumer.
My invention consists primarily of a screw working within a screw box carrying
an index finger or pointer traversing a graduated dial or plate. To the back of
this screw box described, a necked stud is situated, and attached to this stud a
wire chain or cord communicates to, and operates the main tap, which regulates.
the flow of gas or other fluid from the main supply to the meter or service.
I will describe my invention as applied to a tap or valve regulator.
A quick threaded screw of a length equal to the range of the dial plate, works
within the screw box described, so that on rotating the screw by a milled head on
its summit, a traversing backward and forward movement is given to the screw
box carrying the index finger or pointer and thereby points and indicates upon a
graduated plate or dial the exact amount of gas that should be allowed to pass from
the main supply pipe to the meter or service.
Thus a person by rotating the screw connected to the indicating, apparatus
described, may regulate and control to a great nicety, the amount of gas it is.
desirable to allow to pass through the meter or service compatible with the number
of lights being used.
As before described the controlling is effected preferably at a distance from the
meter and main tap, and thus motion imparted to the screw described, changes the
position of the lever (through the wire chain or cord) of the main tap or valve
regulator in both directions, that is to say; the said screw and parts connected
with it raises the tap or valve lever in one direction only, and liberates to the
desired extent in the other direction. The desired returned movement being effected
by a counterpoise weight or by a coiled or other spring.
There is thus produced an apparatus and appliances connected therewith both
simple in their construction, efficient in their action, and thereby effecting great
economy in the consumption of gas.
Having explained the nature of my. Invention, I will proceed to describe with
reference to the accompanying Drawing, the manner in which the same is to
performed.
Figure 1 represents in front elevation, a gas supply regulating apparatus
constructed according to my Invention for controlling the flow or passage of
gas, from the principal main or supply pipe to the meter or service. Figure 2
is the same with dial plate and cover removed exhibiting the actuating mechanism.
Figure 3 is a longitudinal vertical section of figure 1 taken on the dotted lines.
Figure 5 is a transverse vertical section of the apparatus taken through the screw
box and parts connected therewith. Figure 6 shows a plan of the screw box,
figure 7 a side elevation of the same; and figure 8 is a section of the same.
Figure 4 shows the gas supply controlling apparatus and appliances connected
therewith attached to a main tap in communication with a gas meter; the same
letters of reference indicate the same parts in each figure of the drawing.
A is a quick threaded screw working with a screw box B, carrying a pointer
or index finger B2, for pointing or indicating upon a graduated scale, the exact

page_text: amount of gas that should be allowed to flow from the main supply. The screw A
is surmounted by a milled head A2, for rotating the said screw. C is a rod or
wire attached by screwing or otherwise to the screw box B, as best seen in figure 3,
which passes through an opening in the bottom of the case; and connected to the
looped end of the said rod or wire, a chain or other connection D is attached to
the lever of the main tap E figure 4, whereby the said lever is raised or lowered.
F is the box or casing enclosing the screw and parts connected therewith; and
F is the covering for the same. G is a counterpoise weight for lowering the lever
on slackening the chain D-H is the inlet main, and I is the meter or measurer.
D³ is a screw swivel for lengthening or shortening the communicator D, for setting
the pointer to the dial.
The action of the apparatus is as follows. On propelling or repelling the
terminal mount A², a rotary movement is imparted to the screw A, which said
movement causes the screw box B, to travel backward and forward within its
case; the pointer or index finger B² carried by the said screw box, is thereby
caused to traverse the graduated plate or dial shown at figure 1, and so indicate
the quantity of gas that shall be allowed to pass froin the inlet main through the
meter, compatible with the number of lights to be used. The screw box B, slides
between guide cheeks F³ F³ which steadys the traversing of the pointer. The
upward or downward movement of the said screw box B, and with it the rod C,
shortens or lengthens the chain or other connector D, outside the case F; and
thereby raises or lowers the lever E of the tap E2, and so admitting only a
determinate or fixed amount of gas to flow or pass from the inlet or supply pipe H,
through the meter I and thence to the burners to be burned.
The screw A, is provided with a reduced neck or shoulder A³, which bears upon
the bottom of the case. A glass plate F* covers or protects the dial and finger
from injury. By the use of the above apparatus great economy incidental in the
consumption of gas is thereby saved to the consumer.
Although I have only described my invention as applicable for economically
regulating the supply of gas, yet my said invention is equally applicable for cutting
off the entire supply of gas when necessary, whether the said main tap be near to
or at a distance from the said regulator.
Having now described the nature of my invention, and the manner in which
the same is to be performed, I wish it to be understood that I do not limit
myself to the precise details herein described and illustrated, as the same may be
varied without departing from the nature of my said Invention; but I claim as
my Invention.
First. The general arrangement and combination of the parts of gas controlling
or regulating apparatus and appliances connected therewith, herein-before described
and illustrated in the accompanying Drawing.
Secondly. The screw A, and screw box B, carrying the pointer B³, and rod C,
for hauling in and paying out the chain or line D, for the purposes described and
set forth in the accompanying drawing.
In Witness whereof, I, the said George Philippe Lemprière, have hereunto
set my hand and seal, this twenty seventh day of October, in the year of our
Lord, one thousand eight hundred and eighty three.
