PROVISIONAL SPECIFICATION.
Improvements in Ordinary Gas Chandeliers.
I, CHARLES DUDLEY AUSTIN of Manor Chare Newcastle-on-Tyne Engineer
do hereby declare the nature of this invention to be as follows:-
:-
This invention consists in attaching by screwing or other means to the bottom or
under side of the distributing chamber or globe to which the burner arms are
attached & in a direct line with the gas supply tube attached to top side of said
distributing chamber, a tube long enough to extend downwards through the
ornamental fittings sufficiently for the purpose required. This tube is made solid
for about at its upper end, which solid part is drilled & tapped to receive a
screwed valve spindle carrying on its upper end a valve to operate on or regulate
the amount of gas discharged from the main supply tube into the distributing
chamber. The aforesaid spindle projects through the lower end of the regulating
tube which is at that part provided with stuffing box and gland. At underside
of stuffing box a milled disc is fixed to the valve spindle, which when turned
in either direction raises or lowers the regulating valve & correspondingly
diminishes or increases the supply of gas at will. The valve spindle may be
made tubular with blank end to screw on below the milled regulating handle,
when wished therefore a screwed nipple or cock with suitable end for insertion
into india rubber tube may be substituted for blank end and flexible pipe attached
to same to carry gas to reading lamp at any desired level below or distance from
the chandelier.
The regulating spindle when solid might be screwed into the lower end of the
supply tube & be cut away in slanting direction to regulate the passage of the gas
at the speed required. The solid spindle would, in this case, pass through a packed
gland fixed in bottom side of the distributing chamber.

Improvements in Ordinary Gas Chandeliers.
I, CHARLES DUDLEY AUSTIN of Manor Chare, Newcastle-on-Tyne, in the
County of Northumberland, 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:-
This invention has for its object, to prevent roaring or blowing of gas burners
by providing effectual means for the simultaneous & instantaneous adjustment of
all the burners on the chandelier, to any variation of pressure, and consumption of
gas, to produce a steady light perfectly free from flickering and consequent injury
to sight, and to enable the gas to expand on its way to the burners, so as to be
more thoroughly consumed on issuing therefrom by absorbing the requisite amount
of air, thus preventing waste of gas and consequent vitiation of air, so deleterious
in apartments and such like confined spaces, as well as damaging to the contents of
same.
This invention consists in attaching by screwing or other means, to the bottom
or under side of the distributing chamber or globe, to which the burner arms are
attached, and preferably in a direct line with the gas supply tube, attached to top
side of said distributing chamber, a tube formed to receive a screwed valve spindle,
carrying on its upper end a valve to regulate the amount of gas discharged from
[Pil

page_text: the main supply tube, into the distributing chamber. The aforesaid spindle, which
projects through the lower end of the regulating tube, is provided with a stuffing
box and gland, and when turned in either direction, raises or lowers the regulating
valve, and correspondingly diminishes or increases the supply of gas at will.
The valve spindle is sometimes made tubular, with blank end to screw on
below the milled regulating handle, or when desired, a screwed nipple or cock
with suitable end for insertion into india-rubber tube, may be substituted for the
blank end, and flexible pipe attached to the same to carry gas to a reading lamp or
the like.
The regulating spindle when solid, may be screwed into the lower end of the
supply tube, and be cut away in a slanting direction to regulate the passage of the
gas. The solid spindle would in this case, pass through a packed gland, fixed in
the bottom side of the distributing chamber.
A chandelier, when fitted with this appliance, can be lighted, and the burners
turned down to a point, with the gas cocks full open, till the apartment is
required to be lighted, or on leaving the room, for any length of time. Constant
cracking and breaking of gas globes from too sudden application of heat, is also
avoided by its use.
Referring to the four sheets of drawings hereunto annexed :-
Fig. 1. represents a vertical section of an apparatus, showing its application to
the distributing chamber of a four-light chandelier. A tubular casing a is secured
to the bottom of the distributing chamber b, and extends downwards, terminating
in the stuffing box c, through which passes the valve spindle d, carrying a conical
valve e, which on turning the spindle in one or the other direction by means
of the milled head f, is caused by means of the screw thread g, working in the
screwed bush h, secured to the casing a, to open or close the orifice of the gas
supply i.
Fig. 2. represents in vertical section an arrangement similar to that shown in
Fig. 1, but, instead of the solid valve spindle d, a hollow spindle d¹ is employed,
terminating in the nipple cock for the purpose of connecting to a flexible tube, to
supply gas to a reading lamp or the like.
Fig. 3. represents a vertical section of another modification of the arrangement
shown in Fig. 1, in which the conical valve e and screwed bush h are dispensed
with, the end of the spindle d being formed with a screw threaded plug m, to work
in a corresponding socket thread in the interior of the gas supply pipe i, and being
formed, either with inclined flats on its circumference, or having a wedge-shaped
notch n, cut in it, so that as the spindle is rotated, and its end advanced or with-
drawn, the passage for the gas is gradually diminished or increased, as will be
clearly understood.
Figs. 4 and 5. represent vertical and horizontal sections of an arrangement with
horizontal regulating plug valve. The plug valve spindle d passes through a
stuffing box c and screwed into an elbow o, forming a prolongation of the supply
pipe i.
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. A regulating device for gas chandeliers, comprising a valve carried by a
spindle passing through a stuffing box in the distributing chamber, and operating
in conjunction, with the gas inlet orifice of the supply pipe, substantially as
described, and for the purpose set forth.
2. A gas regulating device for chandeliers arranged and constructed, substan-
tially as described, with reference to Fig. 1. of the drawings.
3. In a gas regulating device for gas chandeliers, the employment of a hollow
valve spindle with nipple cock, substantially as described and for the purpose.
specified.
4. A gas regulating device for gas chandeliers consisting of a plug spindle with

page_text: one or more flats or notches, working into the inlet orifice of the supply pipe, the
whole arranged, constructed and operating, substantially as described with reference
to Fig. 3. of the drawings.
5. A gas regulating device for gas chandeliers with horizontal valve spindle,
arranged and constructed substantially as described with reference to Figs. 4 & 5
of the drawings.
