Improved Apparatus for Turning on and off or Regulating the
Supply of Gas for Lighting and other Purposes.
I, JAMES BAILEY of Charles Street, Bolton in the County of Lancaster, Biscuit
Manufacturer, do hereby declare the nature of my said invention to be as follows:-
This invention has for its object that of providing means whereby the supply of gas
for lighting and other purposes, such as, gas stoves, ovens, &c., can be regulated by
simply moving the swivel or gas pipe attached to a taper plug in one or other direction.
The socket receiving the taper plug is provided with a taper or angular recess.over or
round which a hole or passage in the taper plug passes by the swivelling action of
the gas pipe connected to the taper plug. The hole in the taper plug can be
moved from full open to the least possible amount of opening between itself and
the taper or angular recess so as to allow of the least possible light, the latter
heing determined by an adjustable stop attached to the socket or otherwise in
any convenient manner. The adjustable stop is constructed to allow of the taper
plug being swivelled to extinguish the light. This invention is designed to dispense
with the old and objectionable gas tap.

page_text: Supply of Gas for Lighting and other Purposes.
I, JAMES BAILEY of Charles Street, Bolton in the County of Lancaster, Biscuit
Manufacturer, do hereby declare the nature of my said 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 has for its object that of providing means whereby the supply of
gas for lighting and other purposes, such as, Gas Stoves, Ovens, &c., can be
regulated by simply moving the swivel or gas pipe attached to a taper plug in one
or other direction. The socket receiving the taper plug is provided with a taper
or angular recess over or round which a hole or passage in the taper plug passes
by the swivelling action of the gas pipe connected to the taper plug. The hole in
the tapér plug can be moved from full open to the least possible amount of opening
between itself and the taper or angular recess so as to allow of the least possible
light, the latter being determined by an adjustable stop attached to the socket or
otherwise in any convenient manner. The adjustable stop is constructed to allow of
the taper plug being swivelled to extinguish the light. This invention is designed
to dispense with the old and objectionable gas tap.
Fig. 1 is a sectional elevation of my improved apparatus for turning on and off
or regulating the supply of gas for lighting and other purposes-Fig. 2 is a plan
of same Fig. 3 is a side elevation of Fig. 1 showing stop to determine the full
open position of the swivel-Fig. 4 is a sectional plan through line F, G. in Fig. 1,
and Fig. 5 is an elevation of the plug with the gas pipe swivel removed to show
the taper or angular recess for regulating the light.
In all the figures the same letters are used to indicate corresponding parts.
A is the gas pipe secured to the swivel socket B mounted on the taper plug C,
and secured by the nut D. Eis the inlet for gas into the chamber H in the plug C,
from whence it passes through the holes K, L, and N into the gas pipe A the
outer end of which is supplied with an ordinary gas burner. The holes K and L
are connected by the angular recess M as in Figs. 4, 5, and 6, which allows of the
gas being supplied at full bore when the hole N in the swivel socket B is at any
point between the holes K and L. The angular recess M extends slightly beyond
the hole L and is tapered to a point to gradually decrease the area of the same for
the purpose of reducing the outlet for gas when the swivel socket B is in the
position shown in Fig. 4. In case it is desired to maintain a small light on the
burner on the end of the pipe A to dispense with the necessity of lighting the same
every time it is required the 'swivel socket B is arrested by the stop P, which can
be set for the purpose as in Fig. 4. The stop P is attached to the ring R mounted
on the inlet end of the plug C, and is secured in any desired position by the screw S.
To prevent the hole N in the swivel socket B passing the hole K in the plug C the
stationary stop T is fixed to the outside of the same as in Figs. 1, 2, and 3.
When

page_text: it is desired to extinguish the gas light from the burner the stop P is set back as
in Fig. 6 to ensure the opening N in the swivel socket B being closed. The plug
and its appendages are secured to a wall or other place by means of the brackets V
or their equivalents.
Fig. 7 is a front elevation of another modification of my invention-Fig. S is a
side view of same, and Fig. 9 is a plan.
In this modification the position of the gas pipe is regulated by means of the
quadrant W attached to the plug piece X in lieu of the stop P before described.
The quadrant W is provided with the adjustable stops Y secured in the slot Z by the
nuts J. On the swivel socket B is mounted the projection I which moves in the
slot Z, and operates against the stops Y to arrest the movement of the gas pipe A.
Fig. 10 is a side elevation of another modification of my invention wherein
the same can be applied to existing or other gas brackets, and Fig. 11 is a plan of
samé.
In this arrangement the socket B is stationary and the plug C movable. To the
upper end of the plug C is attached the gas pipe A. To the outside of the socket B
is attached the quadrant W provided with the slot Z, in which are mounted the
adjustable stops Y secured in any desired position therein by the nuts J. The
stops Yare of sufficient length to project into the path of the gas pipe A when being
swivelled in either direction. The plug C is provided with the holes K, L, and the
recess M, and the socket B with the hole N as in Fig. 1; the gas supply being
regulated by the swivelling action of the plug in the socket B.
An important feature of this invention is that a considerable saving in gas will be
effected, especially when employed in connection with Bakers' and other ovens where
it is necessary to be constantly using the same, and which when removed therefrom
to allow the oven door to be closed-will automatically reduce the light to a
minimum.
This invention also dispenses with the old and objectionable kind of gas tap with its
numerous inconveniences.
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:
1. In combination with the plug and socket B the use of the tapered or angular
recess M for the purpose specified.
2. In combination with the plug C and socket B the use of the adjustable stop P
for the purpose specified.
3. In combination with the plug (and socket B the use of the quadrant W, slot Z,
and the adjustable stops Y for the purpose specified.
4. The construction, combination, and arrangement of parts forming my invention,⚫
applied and operating substantially as described and as shown on the drawings.
Dated the 23rd November 1888.
