Improvements in Contrivances for Gas Controlling Purposes.
We, JOHN CLARKE of Brannstone Gate, Electrician, WILLIAM HAYNES of
No. 98 Curzon Street, Boot Manufacturers Manager, and FRANCIS ROBINSON
of No. 22 Leamington Street, Foreman of Boot Factory, all in Leicester in the
County of Leicester, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in contrivances for gas controlling
purposes that is to say to control the light or lights by shutting off the gas to a
glimmer or in the use of a pilot jet, and is applicable more particularly to gas
stands used by finishers in the process of finishing boots or shoes, but which can
also be applied for other gas controlling purposes such as controlling a whole room
gas jets at one time by the employment of the frictionless valve contrivance
hereinafter described.
of
In applying our invention to "finishers gas stands" we arrange the controlling
devices in the following manner. The tool pan is provided with an arm carrying
a balance weight of the ordinary kind, which is carried in a suitable bracket or
column in base plate adapted to be screwed to a bench or the like.
In casting the said base plate two apertures, holes or channels are left on the
under side of same, one to convey the gas to the pilot jet independently of the
other, which supplies a "Bunsen burner" or what is commonly known as a
"finishers blue light" from a gas supply at the end having an ordinary gas cock
connected thereto, the supply of gas to the valve governing the blue light passes
through a hole in the rim of the bottom portion or box of the valve contrivance
and it enters the supply pipe through a conduit or aperture in the bottom of the
valve box when the valve is open to supply the Bunsen burner immediately under
the tool pan.
The object of our invention is to provide means to operate and shut off the said
"blue light" when the irons are not on the stand heating; or when it is not
necessary to have the light, this is accomplished by the aid of the frictionless valve
herein referred to, when the tool or tools are taken off the pan it rises and the
balanced end descends and carries with it a rod linked or otherwise attached to the
arm of the tool pan, to this is connected a valve rod fitting through the cap or
upper portion of the suitably packed valve box, to the lower end of the rod is
attached an inverted cup valve, which descends upon, and closes over the conduit
and shuts off supply, the cup at the same time entering a layer of quicksilver put
in the bottom of the valve box round the wall of the conduit, through a screw
capped hole and channel in the rim thus obviating any chance of spilling the
quicksilver in any way.
The pilot burner is arranged up the outside of the "Bunsen burner," but unlike
ordinary gas stands the jet is not conducted to the inside thereof, but left outside
When the tools are
the "blue light" igniting at the upper edge of the tube.
again placed on the pan, the valve cup is raised and the "blue light" is immediately
obtained for heating the tools.
In applying the aforesaid frictionless valve contrivance to control a number of
lights at one time in places of amusement, factories, institutions or railway
platforms or other places where "pilot jets" are employed to ignite large burners,
or the lights are required to be put down to a glimmer we arrange that the top of
the cup valve rod shall be forced in by pressure, or heat whichever may be the

in the manner herein before described.

COMPLETE SPECIFICATION.
Improvements in Contrivances for Gas Controlling Purposes.
We, JOHN CLARKE of Brannstone Gate Electrician, WILLIAM HAYNES of
No. 98 Curzon Street Boot Manufacturers Manager, and FRANCIS ROBINSON
of No. 22 Leamington Street Foreman of Boot Factory, all in Leicester in the
County of Leicester, 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 gas controlling
'purposes that is to say; to control the light or lights by shutting off the gas to a
glimmer or in the use of a pilot jet, and is applicable more particularly to gas
"stands used by finishers in the process of hand finishing boots or shoes, but which
can also be applied for other gas controlling purposes such as controlling a whole
room of gas jets at one time by the employment of the frictionless stop valve
contrivance hereinafter described and shown in the sheet of drawings annexed
in which
Figure 1. is a side elevation of a finishers tool heating machine, or gas stand
forming part of our invention and constructed in accordance with the same.
Figure 2. shows our contrivance for shutting off the gas to a glimmer' under
pressure; both views being partly in section.
Figure 3; Sheet 2 shows the base plate C of the gas stand showing in dotted
line the channels, or might be pipes c² and c, with inlet hole F to well G. and
Figure 4 is a section through the casting of the base of gas stand.
"Iu'a finishers gas stand as illustrated the gas control is arranged and operated in
the following manner.
A is the tool pan having the arm a' carrying the weight a² as usual, and carried
in the column B secured to the base C, which with its feet c¹ and projecting
channels or pipes c² and c³, is adapted to fit in a bench 'or the like' hidden from
fview. The gas is conducted to the pilot jet D through the channel e³ from.supply
secured on the threaded outer end thereof, and admitted to the gas control through
da small hole F, in the body or well G. When the tools are placed upon the pan A
the arm a¹ rises and brings with it the cup valve H from off the conduit g, and so
admitting the gas to pass into the channel or pipe'e, and through the gas burner e,
into the
Bunsen "burner E, when it is ignited by the pilot jet. Upon the removal
"of the tools when sufficiently heated the pan A rises, and the rod 1 secured to the
arm'a by pin or cotter a³ through hole a, and attached to the valve rod J, working
in the cap K, descends, and the cup valve H covers the conduit g, at the same time
entering the quicksilver g¹ in the well, so shutting off completely the blue light for
heating the tools.
i
The quicksilver is fed to the well through the passage g² which is closed by
screw (Fig. 2 Sheet 1). Between the cap K and valve box G, is suitable
*packing L, held in place by the washer j', and cap K, secured by screws ...
n
The rings of the tool pan A are secured to the arm a¹as shown at N. The
ledge M, keeps the pan from falling lower.
In applying our frictionless valve for other controlling purposes such as in
places of amusement, factories, institutions railway platforms or other places, we
arrange the gas control as seen in Figure 2 Sheet 1 of the drawings wherein the cup
valve His forced in by pressure of the spring o*, or its equivalent to shut off the

page_text: gas. To the eletro magnet O is connected insulating wires such as o', carried
through suitable non-conductors o³, the said magnet, upon the attendant operating a
push not shown attracts the contact piece of the electro fulcrumned lever o³, when
the cup valve H will rise and allow the gas to pass into the pipe c³, to any part
desired. When contact is broken the open spring of comes into operation. This
arrangement can be applied to finishers gas stands or other similar appliances
if desired.
The push of any ordinary kind can be placed in any convenient position, and at
any distance from the gas control, to operate it. To accomplish the control by
heat instead of as above described we may employ an electric thermometer
graduated of any useful and well known kind which can be regulated to any desired
heat to operate the valve rod J, and cup valve H, the operation being directly
opposite to the one previously mentioned.
We are aware that mercury valves have been long since employed to govern or
regulate supply to lights but ours is ostensibly for closing main supply.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1. Controlling the blue light of a finishers gas stand by the employment of a
mercury stop valve arranged for closing main supply in the manner described.
2. In combination with a machine for heating tools of character described a
controlling device consisting of a cup valve such as H, operated by the rising and
falling of the tool pan arm substantially as specified.
3. In a gas tool heating stand of the character described the construction of a
valve box, or quicksilver chamber G, with conduit -g, and channels and c³
cast in one with the base plate C, or tubes or pipes connected to form such
channels and c³.
4. In controlling a number of lights such as are used in places of amusement,
factories, institutions or railway platforms the employment of a frictionless valve
contrivance operated and operating in the manner substantially as described.
