PROVISIONAL SPECIFICATION.
Improvements in Contrivances for Controlling the Supply of Gas to
Burners.
I, FREDERICK LOWE of No. 2 Montague Road Clarendon Park Knighton in the
county of Leicester, Machinist, do hereby declare the nature of this invention to be as
follows:---
This invention relates to improvements in contrivances for controlling the supply
of gas to burners, to regulate the flame to any height or to lower the same, or to
totally put out, or stop the supply of gas to the burners if necessary.
It is well known that in Railway Stations, and large Warehouses, Theatres, and
other places of amusement the gas lights run perhaps the entire length, or partly
the length of the platform, or room, which are required at intervals to be turned
down to scarcely a glimmer, this is done by regulating the supply from the meter, or
by a wrench or key to turn the gas cock, on or off.
The object of my invention is to provide a contrivance or contrivances that will
effectually attain these results either in a whole row of lights, or to a single bracket
more satisfactory than by the different appliances now in uso, that will enable anyone
to lower the gas so that just a glimmer of light is left with certainty by the operator
or person taking hold of a knob at the lower end of a spindle and pulling the spindle
down which causes a check valve at the top of the spindle to close on to a valve
seating inserted in the upper arm of the casing thus when valve is shut down a small
quantity of gas passes by "grooves" or "flutings" cut in the spindle, under the check
valve, when by pushing the spindle up the valve opens rendering the flutings useless
and the supply pipe receives ordinary quantity of gas desired the contrivance is
constructed so as to screw upon the lower end of an upright, or in a suitable position
in horizontal piping, or gas fittings-to effect this I make a metal casing having three
or more arms, the horizontal ones are screwed; to which are attached the outlet pipe,
or pipes, the lower vertical arm having a stuffing box inserted therein packed with greasy
cotton waste, or a washer of felt and the like, or Asbestos, through this passes the
lower part of the spindle-and carried up the centre or bulb into the upper vertical
arm, the said upper arm having a bush therein through which passes the upper end
of the spindle carrying a cap, or check valve, the contrivance is then screwed into the
end of the supply pipe.

Improvements in Contrivances for Controlling the Supply of Gas to
Burners.
I, FREDERICK LOWE of No. 2 Montague Road Clarendon Park Knighton in the
county of Leicester, Machinist 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 relates to improvements in contrivances for controlling the supply
of gas to burners to regulate the flame to any height, or to lower the same, or to totally
put out, or stop the supply of gas to the burners if necessary.
It is well known that in Railway Stations, large Factories and Warehouses, Theatres
and other places and resorts for public amusement and recreation the gas lights runa

page_text: perhaps the entire length of the platform room or structure and which are turned
down at intervals to scarcely a glimmer when the light is not required, this is done
by regulating the supply from the meter, or 'by a wrench or key at the turn cock.
But the object of this invention is to provide.a contrivance or check valve that
will effectually attain these results either in a whole row of lights or to a single
bracket more satisfactory than by the different appliances now in use, by which
anyone will be enabled to lower the gas that just a glimmer of light is left, or
none by manipulating the knob at the outer end of the contrivance, and pressing
inwards, or pulling outwards, as occasion may require.
That my invention may be well understood a drawing is hereunto annexed to
which I will now refer to marked Figure 1. which is a sectional view of an iron
four way gas junction A, or metal casing consisting of three or more arms, the
outlet pipes or gas pendant being attached to the horizontal arms B, in the lower
vertical arm C, is a stuffing box D, which is packed with greasy cotton waste, or a
washer of india-rubber or felt and the like, or asbestos packing, round the lower part
of the spi.dle E, which is carried through the upper vertical arm F, through brass
bushes G, the upper end of the spindle carrying a cap, or check valve, H, by the
projecting screwed end I, it is attached or connected to the supply pipe not shown
which will be well understood, the upper part of the spindle E, under the check
valve is filed down, or grooves, or flutings cut therein at g'. When the pusher or
knob J, is pressed inwards the check valve is moved out of its seating, and by pulling
the knob outwards the check valve is firm in its seating, a small slot g' is made in
the cap or check valve so that a small supply of gas may come from the supply pipe
should the stuffing box happened to get clogged, when the check valve is down as
shown in the drawing a small quantity of gas passes by the grooves or flutings cut
out in the spindle and a certain quantity of gas is obtained, that a tight joint is made
in the lower part of the contrivance the nut K, is fitted upon the spindle and screwed
firmly in the lower arm to tighten up the packing.
Fancy or ornamental casings may be made to suit the gas fittings made of brass
or other suitable material.
For controlling the gas in Theatres either for producing stage effects, or to control
the foot or ceiling lights is this invention useful, they may be fixed in a suitable
recess and covered by a lock up covering so that only the person in anthority could
gain access to them, they may be put in the passage, or outside the building so that
if a fire was to take place, and the gas meter could not be got at, the gas could be cut
off by the contrivance herein before described.
:
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is
A controller to regulate or shut off the supply of gas to burners consisting of a
casing enclosing a spindle or bye pass with grooves or flutings cut out therein and
carrying a cap or check valve operated by a pusher or knob on the outer free end of
the spindle in the manner and for the purpose substantially as herein before described
and set forth.
