Improvements in and Connected with Taps for Gas and other
Fluids.
I ARTHUR PAGET of Loughborough in the county of Leicester Engineer do hereby
declare the nature of this invention to be as follows:-
There are many purposes for which gas and other fluids are used when it would be
desirable to be able to have a tap that could be quickly, easily, and exactly manipulated
so as to lessen the gas supply to a regulatably fixed smaller amount than the full flow
in order to turn down the gas-supply without extinguishing the light, and the tap
should be also able to allow the gas supply to be entirely turned off with ease and
certainty, and it is very desirable that both these changes of the gas-supply should be
able to be easily and rapidly effected with certainty by an unskilled person acting
quickly or hastily. To effect this I construct the gas-tap with a handle one end or
both ends of which works or work during its movement of partial rotation against a
sector which is kept in springing contact with the handle, and the sector has at one
end a projection which prevents the handle of the tap being moved further than is
necessary to put the tap fully open; the sector is also arranged so that it has a notch
or stop at a point of its circle as will arrest the motion of the handle of the tap when
it has been moved to the point corresponding to the desired reduction of the gas-flow.
The said sector and handle are likewise so arranged that by pushing or pulling the
sector out of contact with the handle or the handle out of contact with the sector the
tap can be further moved beyond the last named stop or projection, and then
the handle can be moved to another stop or projection that arrests it in that position
which will allow the gas-supply to be entirely turned off.
In some cases instead of the sector being arranged to spring so as to be kept in
contact with the handle and to allow it to be pulled or pushed out of contact with the
handle the sector can be made rigid and the handle be made to spring into contact
with and be removable from contact with the sector.
In some cases it is also desirable to guard against a careless manipulator leaving the
handle of the tap at any point between the point of full flow of the gas and the

regulatably fixed point to which it is desired that the gas should be turned down, and
in such cases the sector is constructed so that it has a tendency to force the handle
either towards the stop against which it should bear when the

"full-on
is
gas
toward the stop it should rest against when the gas is "turned low" and thus the
handle will not remain at rest anywhere between these two points. Or where it is
desirable the sector and handle can be similarly made so that the handle will not rest
at any point between "full-on" and "shut-off."
It is also desirable in some cases that when the gas-supply is lessened so as to turn
the gas to a low point of combustion the flame should be shielded from draughts, wind,
or eddies of the surrounding air which might extinguish the flame or affect it in
other ways. To effect this I in some cases construct the tap so that the movement of the
handle to lessen the flow of gas lifts or moves a cylindrical or globular shield so that
it protects the lessened flame from being easily extinguished by draughts, wind, or
eddies of air, and when the handle is moved to increase the gas flame, such movement
of the handle will lower or remove the shield so that it does not obstruct the light or
heat of the gas flame.
My invention is applicable to taps for gas-lighting, to taps for gas-heating, and taps
for all fluids and gases, where it is desired to be able to readily lessen the gas-supply
to a regulatably fixed smaller amount than the full flow, or to protect a lessened flame
from being easily extinguished.

page_text: I ARTHUR PAGET of Radmoor Loughborough in the County of Leicester 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:
The first part which I will describe relates to the use of a tap that can be quickly
easily and exactly manipulated so as to lessen the gas supply to a regulatably fixed
smaller amount than the full flow in order to turn down the gas supply without
extinguishing the light, and the tap is also able to allow the gas supply to be entirely
turned off with ease and certainty by an unskilled person acting quickly or hastily.
To effect this I construct the gas tap with a handle, one end or both ends of which
works or work, during its movement of partial rotation against a sector which is kept
in springing contact with the handle, and the sector has at one end a projection which
prevents the handle of the tap being moved further than is necessary to put the tap
fully open; the sector is also arranged so tha it has a notch or stop at such a point of
its circle as will arrest the motion of the handle of the tap when it has been moved to
the point corresponding to the desired reduction of the gas flow. The said sector and
handle are likewise so arranged that by pushing or pulling the sector out of contact
with the handle or the handle out of contact with the sector the tap can be further
moved beyond the last named stop or projection and then the handle can be moved to
another stop or projection that arrests it in that position which will allow the gas
supply to be entirely turned off.
In some cases instead of the sector being arranged to spring so as to be kept in
contact with the handle and to allow it to be pulled or pushed out of contact with the
handle the sector can be made rigid and the handle be made to spring into contact
with and be removable from contact with the sector.
Figures 1. 2 and 3 on sheet one show an arrangement for carrying out this part of
my invention. Figure 1 is a front elevation of a gas tap and adjacent parts showing
the gas full on Figure 2 is a side view in section of the same Figure 3 is a plan of
the same.
To the gas tap A is attached a sector A¹ in which there is a slot or groove for the
purpose of adjusting the adjustable stop A². To the plug A³ is fastened a handle A
which is a spring or able to be sprung backwards and is kept pressing against the
sector A' and so keeps the plug A³ pushed home so as to prevent leakage without
jamming or sticking in the tap A. When it is desired to turn the gas down to the
requisite amount without extinguishing the light, the bandle A is moved in the
direction of the arrow A until it comes into contact with the adjustable stop A2 (which
is adjusted so as to stop the handle when the right amount of gas has been shut off)
and when it is desired to extinguish the light the handle A is pushed clear of the

page_text: stop A and is then moved further in the direction of the arrow A³ until it comes into
contact with the fixed stop A on the end of the sector A¹. It will be evident that in
some cases instead of the handle A springing against the sector A¹ the handle can be
made rigid and the sector A' made to spring against the handle A' and so keep the
plug in place. It will be also evident that in other cases the handle to actuate the tap
can be constructed as a disc with a fixed stop for "Gas full on "and another for
gas off" with a regulatably fixed stop for gas turned low" these stops abutting
against a stop which can be sprung
out of the way of the regulatably fixed stop so as
to allow it to pass by the stop for gas turned low" to the stop for " gas off."
It will be seen that there are great advantages in this arrangement over the ordinary
gas taps as those acquainted with ordinary gas taps will readily see as this arrangement
has the evident convenience of being able to turn the gas at once quickly and easily
without special care to the lowest safe point to keep the Hame alight and this arrange-
ment is free from the trouble experienced in ordinary gas taps when the plug wears
and gets loose and so allows the gas to leak whereas in this arrangement the spring of
the handle A against the sector A¹ keeps the plug gas-tight when new and also takes
up all wear of the plug and the hole in which the plug works which necessarily ensues
from use.
The second part which I will describe relates to the method of guarding against a
careless manipulator leaving the handle of the tap at any point between the point of
full flow of the gas and the regulatably fixed point to which it is desired that the gas
should be turned down as there are some special cases where it is very desirable that
this should not be done, in such cases the sector is constructed so that it has a tendency
to force the handle cither towards the stop against which it should bear when the gas
is "full on" or towards the stop it should rest against when the gas is "turned low"
and thus the handle will not remain at rest anywhere between the two points or where
it is desirable the sector and handle can be similarly made so that the handle will not
rest at any point between "full on" and "shut off." Figures 4. 5 and 6 sheet 1 show
this arrangement. Figure 4 is a front elevation showing a tap and adjacent parts.
Figure 5 is a plan looking down on the top of the tap and figure 6 is a plan looking at
the bottom of the tap. This arrangement is carried out by having an inclined surface
on the sector A' and the handle A and the spring of the handle against the sector or
the sector against the handle has a tendency to force the handle down the incline until
it reaches one of the fixed points.
The third part which I will describe shows the method by which when the gas supply
is lessened so as to turn the gas to a low point of combustion the flame is shielded
from draughts, wind or eddies of the surrounding air which might extinguish the
flame or affect it in other ways. To effect this I in some cases construct the tap so
that the movement of the handle to lessen the flow of gas lifts or moves a cylindrical
or globular shield so that it protects the lessened flame from being easily extinguished
by draughts winds or eddies of air and when the handle is moved to increase the gas
flame such movement of the handle will lower or remove the shield so that it does not
obstruct the light or heat of the gas flame.

Figures 7. 8. 9. and 10 on sheet 2 show this arrangement the same letters refer to
the same parts as in the previous part of this specification. Figure 7 is a front view
showing the tap with the shield in the position it is in when the gas is "full on.'
Figure 8 is a plan of the same. Figure 9 is another front view showing position of
shield when the gas is turned down. Figure 10 is a front sectional elevation. To the
handle A is attached a cam B which when the flame is being turned down comes into
contact with a projection on the shield carrier B¹ carrying the shield B2 which can be
made of brass, glass, earthenware or any other suitable material, then to turn the gas
down the handle is pushed in the direction of the arrow A and the cam will lift the
shield so that when the handle A* reaches the stop A² it will have lifted the shield

easily be seen that by cutting grooves in the plug as shown in figures 11 and 12 a
small supply of gas sufficient to keep the flame alight can be conducted to the burner
after the plug has been turned so as to close the ordinary gas passage.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I desire it to be understood that I do
not confine myself to the exact details herein set forth as such may be varied or
modified without departing from the principle thereof, but I claim as my improve-
ments in and connected with taps for gas and other fluids.
First. The method of constructing gas taps with a handle one end or both ends of
which works or work during its movement of partial rotation against a sector which
is kept in springing contact with the handle and the sector has at one end a projection
which prevents the handle of the tap being moved further than is necessary to put the
tap fully open the sector is also arranged so that it has a notch or stop at such a point
of its circle as will arrest the motion of the handle of the tap when it has been moved
to the point corresponding to the desired reduction of the gas flow. The said sector
and handle are likewise so arranged that by pushing or pulling the sector out of
contact with the handle or the handle out of contact with the sector the tap can be
further moved beyond the last named stop or projection and then the handle can be
moved to another stop or projection that arrests it in that position which will allow the
gas supply to be entirely turned off substantially as herein described with reference to
figures 1. 2 and 3.
"
2nd. The method of constructing the sector so that it has a tendency to forco the
handle either towards the stop against which it should bear when the
is full on
gras
or towards the stop it should rest against when the gas is "turned low" and thus the
handle will not remain at rest anywhere between these two points substantially as
herein described with reference to figures 4. 5 and 6.
3rd. The method of constructing the tap so that the movement of the handle to
lessen the flow of gas lifts or moves a cylindrical or globular shield so that it
protects the lessened flame from being easily extinguished by draughts, winds, or eddies.
of air and when the handle is moved to increase the gas flame, such movement of
the handle will lower or remove the shield so that it does not obstruct the light
or heat of the gas flame substantially as herein described with reference to figures 7.
