PROVISIONAL SPECIFICATION.
Improvements in Gas Taps or Cocks.
I, LAW HEPPENSTALL, of Hope House, Baukfield Road, Huddersfield, in the
County of York Mill Furnisher do hereby declare the nature of this invention to
be as follows :-
The object of my invention in gas taps or cocks is to provide means whereby,
firstly; a full light can issue from the burner; secondly, by turning the tap in one
direction, a small or greatly diminished light will issue from the burner, and on
turning the tap in the opposite direction the light may be extinguished; or in
another case a small light will issue from the burner by turning the tap either to
the right or left hand. According to the present construction of gas taps, the
plug is provided with a stud, which comes into contact with a stop piece when the
gas is turned off.
According to one method of carrying out my invention, one
piece is made or so situated with regard to the stud that on the said stud being
turned against the stop piece the light will not be extinguished, but on the plug
being turned the opposite way the stop piece is so situated as to permit the stud
to go sufficiently far as to extinguish the light.
According to another method, I make a groove in the plug of the tap; 'I also
make a cavity within the part where the plug works, the arrangement being such
that when the plug is turned so as to bring the stud against the stop piece, the
channels or grooves are placed in communication with each other in such a manner
as to supply a small amount of gas to the cavity from which it escapes to the
burner whereby a small light is obtained, but on the plug being turned suffi-
ciently far as to bring the stud against the other stop piece the light is
extinguished.
pass
According to another method, a groove is indented into the plug all around its
circumference, which permits a small quantity of gas to enter the
and
groove
to the burner, in which case a small light is given off whether the plug be turned
to the right or left.
According to another method, a horizontal hole is pierced through one half of
the plug, and it is so situated in the plug that when the tap is turned off, the hole
is opposite the gas supply whereby a small light is given off when the tap is
supposed to be shut off."

Improvements in Gas Taps or Cocks.
I, LAW HEPPENSTALL, of Hope House, Bankfield Road, Huddersfield,
Yorkshire, Gas Lighting Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
nd ascertained in and by the following statement :-
According to the present construction of gas taps, the plug is provided with a
stud, which comes into contact with a stop piece when the gas is turned off. The
object of my invention in gas taps or cocks is to provide means whereby, firstly,
a full light can issue from the burner; secondly, by turning the tap in one
direction, a small or greatly diminished light will issue from the burner, and on
turning the tap in the opposite direction the light may be extinguished; or in

another case a small light will issue from the burner by turning the tap either to
the right or left hand.
Such being the nature and object of my invention, I will now proceed to
describe the same more fully, and for that purpose make reference to the annexed
sheet of drawings illustrative thereof, wherein
Fig. 1 is sectional elevation of an ordinary plug gas tap and Fig. 2 is sectional
plan of the same.
a represents the plug, capable of being turned around backward and forward
within the casing b. The gas enters the pipe e through the hole d of the plug a
and passes out of the burner e in the ordinary manner. As is usual in this
description of tap, the plug a is provided with one stud h, which, in order to shut
off the gas, is turned in either direction against one or other of two shoulders or
stop pieces arranged opposite each other. According to my invention I employ
two studs, and I so arrange one stop piece as to stop one of the studs before the
gas is entirely shut off, as shewn in section Fig. 2, whereby a small light or flame
will be allowed to burn, but when the plug a is turned the opposite way, the stop
piece is so situated as to allow the plug to shut the gas off entirely, but when the
hole d is opposite the in-coming gas a full light or flame is obtained.
By the employment of two studs and the placing of one stop piece so that the
gas cannot be entirely shut off, the tap possesses three functions, namely the gas
can be entirely shut off, or a full light can be obtained, or a small light, as desired.
In Figs. 3 and 4 I have shewn another construction of tap having the three
functions possessed by the tap previously described. In this case 1 form a groove f
in the periphery of the plug a, such groove extending only half way around the
plug so that when the plug occupies the position shewn in the drawings, where the
groove is presented to the in-coming gas, a very small portion of the said gas
will escape through the groove and enter the ordinary hole or passage d of the
plug, and pass therefrom, as will be understood from the plan view Fig. 4, into
another groove or cavity g made within the casing b, where such said small
quantity of gas passes to the burner e whereby a small light is obtained. On the
plug a being turned back or half way around until the stud h comes against a
stop piece at the opposite side of the tap, the solid half of the plug and not the
grooved part is presented to the in-coming gas, whereby the gas is entirely shut off
and no light obtained; but when the hole in the plug is presented to the in-
coming gas, a full light is obtained.
By forming a groove f in a portion of the plug, and by forming the cavity g in
the tap casing, the tap possesses three functions, namely, the gas can be entirely
shut off, or a full light can be obtained, or a small light, as desired.
In Figs. 5 and 6 I have shewn that the groove f in the plug a may be formed
all around its circumference, which permits a small light always to be burning;
or on the other hand, when the hole d in the plug is presented to the in-coming
gas, a full light can be emitted. With this tap the cavity g is not required, and
the gas cannot be entirely shut off.
In Figs. 7 and 8 1 dispense with the groove in the plug and instead thereof form
in the plug a small opening or aperture i, which allows a small portion of gas to
.pass into the hole d and into cavity g for the purpose of giving off a small light,
but when the solid end of the plug is presented to the in-coming gas it is entirely
shut off. This tap also has three distinct functions, namely, a small light can be
given off, or a full light, or the gas may be entirely shut off.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In a gas tap, the plug a provided with two studs h and two stop
pieces, so placed as to permit the gas to be entirely shut off, or to leave a small
light burning, or to permit a full light to burn, all arranged as described and shewn
in the drawings, Figs. 1 and 2.

page_text: Secondly. In a gas tap, the plug a with a groove formed in a portion of its
circumference, in combination with a cavity made in the body of the tap for the
purpose of giving off a small light; such said tap being capable of giving off a
full light, and also capable of shutting the gas completely off, all arranged as
described.
Thirdly. In a gas tap where the light cannot be entirely extinguished, the plug a
with a groove formed around the whole circumference thereof for the purpose of
giving off either a small or full light, as described.
Fourthly. In a gas tap, the plug a with a horizontal hole i communicating with
the ordinary hole d in combination with a cavity 9 for giving off a small light,
such said tap being capable of giving off a full light and also capable of shutting
the gas off completely, all arranged as described.
