Sealed the 21st February 1879, and dated the 30th August 1878.
PROVISIONAL SPECIFICATION left by the said Oscar Siebert at the Office
of the Commissioners of Patents on the 30th August 1878.
OSCAR SIEBERT, of Lisle Street, Leicester Square, in the County of Middlesex,
Gas Engineer. "IMPROVEMENTS IN GAS LIGHT APPARATUS AND ARRANGEMENTS
CONNECTED THEREWITH."
My Invention relates to improved arrangements applicable to gas lighting whereby
I regulate the supply of gas to the burner, ensuring steadiness of the flame; and
also arrangements for sustaining and holding globes which are held without the use
of screws, and such arrangements will enable any size globe to be held securely.
My said Invention consists mainly of the following arrangements-For
regulating the gas to the burner I arrange a screwed socket which is provided with
a seat, in the centre of which is a small opening; above this seat and opening is
the screw, into which screws the burner. The burner at the lower part is provided
with a peculiarly shaped plug which is so formed as to come to a point immediately
over the opening in the seat, the sides being provided with openings so that the gas
issuing from the opening in the seat passes up, around, and thence to the burner, the
regulation being effected by turning the screwed piece, and with it the plug. The
said screwed piece is provided with a triangle or globe holder which is cast with
the screwed piece and plug, or may be stamped by itself and screwed on to the
burner, being stamped to any size required.
Each arm of the triangle or holder is grooved or recessed (or one arm only may,
be so grooved), into which groove or recess a small spring is placed. The spring is
covered by a plate or piece of metal terminating in the clip or piece of metal for

page_text: holding the globe, such clip being passed through an opening made in each arm, the
upper portion being turned inwards to clip the rim of the globe, and the lower part
forming a projection to draw or force the plate in or out to suit the size of the
globe.
A groove is provided through which passes a screw, such screw passing at the
back of the spring and into the sliding plate before described.
The regulator can be applied to any burner, and also the holder or triangle.
A globe or chimney of any kind may be used for my improved apparatus, but in
addition thereto I use clips or pieces of metal so curved as to clip on to the globe.
To these pieces of metal I attach at the upper part a ring of metal so formed as to
receive a concave reflector which is placed in the ring, such reflector serving also as
a smoke arrester.
The clips or pieces of metal I prefer to secure without solder, which I effect by
forming the ends with projections which are passed through openings left in the
ring, and when in position are turned down, securely holding the arms to the
ring.
Sometimes I have two rings which are joined together by the pieces of metal
before described. In this case the lower ring is made of such size as to fit on to the
top of the globe, the upper ring carrying the reflector.
My improved regulating burner before described is particularly useful for billiard
lights. The ordinary arrangement is to have three lights burning horizontally,
whereas by my burner I can with one only (burning vertically) produce as good an
effect without the heat now evolved. To effect this I arrange around the burner a
framework which is formed to fold up, said framework being either square or
oblong, and not round as those now used. Over this framework (which carries the
burner) is passed the shade, which is also formed so as to fold when taken from the
franie.
The frame is provided with a smoke. arrester, which in some cases however can
be dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Oscar Siebert in the Great Seal Patent Office on the 28th February
1879.
OSCAR SIEBERT, of Lisle Street, Leicester Square, in the County of Middlesex,
Gas Engineer. "IMPROVEMENTS IN GAS LIGHT APPARATUS AND ARRANGEMENTS
CONNECTED THEREWITH."
My Invention relates to the construction of an improved regulating gas burner,
whereby I am enabled to regulate the supply of gas to the burner, ensuring
steadiness, economy, and noiseless burning of the flame; also to an improved
triangle or gallery for sustaining and holding globes, by which they are held without
the use of screws, and such arrangement will enable nearly any size of globe to be
hield securely.
I also construct an improved coronet for holding a reflector on globes, and finally
I employ an improved construction of framework and folding shade to be used in

page_text: combination with my improved regulating burner, by which the improved burner
is rendered particularly useful for billiard lights.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which,-
Figure 1 is an elevation of my improved, regulating burner.
Figures 2 to 7, detached details of the various parts of the burner.
Figure 8, plan; and Figure 9, side elevation of my improved gallery or triangle
for holding the globe; Figure 10, plan of the under side of same.
Fignre 10,,section on line A, B, of Figure 8.
Figure 12 is an elevation; and Figure 13 a plan of, my improved coronet for
holding the reflector over the globe.
Figure 14 shews the same applied to a globe.
Figures 15 and 16, full size elevations of one of the clips of the coronet.
Figure 17, plan of a part of the ring of the coronet.
Figures 18 to 25, views of my improved framework for billiard lights.
Figures 26, 27, 28, and 29, views of my improved folding shade for billiard
lights.
My improved regulating gas burner is constructed of a screwed socket a, shewn
detached in elevation, plan, and section, at Figures 2, 3, and 4, respectively, which
socket is provided with a seat b, in the centre of which is a small opening c. Into
the socket and above the seat band opening c is the screw d, into which screws the
burner e properly so called, shewn detached in elevation, plan, and section at
Figures 5, 6, and 7, respectively.
The burner e at the lower part is provided with a peculiarly shaped plug, which
is formed so as to come to a point immediately over the opening c in the seat, the
sides being provided with openings g so that the gas issuing from the opening c in
the seat passes up, around, and thence to the burner. By this arrangement the
pressure of the gas is checked or reduced so as to insure a steady and noiseless flame,
and a waste of gas is prevented; and the quantity of gas passing to the burner
may be further regulated by turning the burner, and with it the plug f, so as to
increase or diminish the space between the seat band plug f. The said screwed
piece or burner is preferably provided with my improved triangle or globe holder,
which may be either cast with the screwed piece and plug as shewn in Figure 11,
or may be made separately, as shewn in Figures 8, 9, 10, and 10%, and screwed on
to the burner.
The improved triangle or globe holder is constructed with three arms h, each arm
being grooved or recessed at i, Figure 11a, which is a top view of one of the arms
(or one arm only may be grooved), and into the groove or recess ȧ a small spring j
is placed. The spring is covered by a plate l or piece of metal terminating in a
clip or claw for holding the plate m, such clips l being passed through an opening n
made in each arm h; the upper portion of the clip or claw being turned inwards,
as shewn, to clip the rim n' of the globe m, and the lower part forming a projection o
by which to draw or force the plate in and out to suit the size of the globe.
A groove p is provided, through which passes a screw q, and such screw q passing
at the back of the spring j and into the sliding plate / before described. By this
construction it will be understood that by drawing the clips outwards, as shewn in
Figure 11, the rim of the globe may be placed in the clips 1, and the clips being
then released their springs ; will draw them inwards and against the rim of the
globe, and thus hold it firmly, as shewn in Figure 31.
Instead of all the arms being provided with moveable spring claws, only one arm
may be so provided, the other two arms having the usual fixed claws, and the
improved triangle or gallery can be used with any ordinary gas burner.
The improved regulator herein-before described can be applied to any burner,
and the improved gallery or triangle may be applied to all burners requiring
globes.
A globe of any kind may be used with my improved regulating burner, but I
prefer to employ with the globe a coronet constructed with clips or pieces of metal r

page_text: curved, as shewn in Figures 15 and 16, so as to clip on to the globe. To these pieces
of metal I attach at the upper part a ring of metal 8 so formed as to receive a
concave reflector t, shewn detached in Figure 30, which is placed in the ring, such
reflector t serving also as a smoke arrester.
The clips or pieces of metal I prefer to secure without brazing or rivetting, which
I effect by forming the ends with projections u, u, which are passed through
openings v, v, left in the ring s, and when in position are turned down as shewn in
the lower part of Figure 17, thereby securely holding the arms to the ring.
Sometimes I have two rings which are joined together by the pieces of metal
before described. In this case the lower ring is made of such size as to fit on to the
top of the globe, the upper ring carrying the reflector.
My improved regulating burner before described is particularly useful for billiard
lights. The ordinary arrangement is to have three lights burning horizontally,
whereas by my burner I can with one only (burning vertically) produce as good an
effect without the heat evolved. To effect this I fix around the burner a frame-
work w, w, of wire with arms a jointed to each corner so that the arms may be
folded up as shewn in Figures 21 and 22. The said framework is shewn oblong in
the Drawing, but it may be square if required.
The upper ends a¹ of the arms a pass into tubular openings y in the sheet-metal
frame formed with inclined sides and ends, and provided at each corner with a
vertical projection z' which fit into the tubular pillars a' of the sheet-metal cap or
reflector b¹, which also forms a smoke arrester.
Figure 18 is a side elevation; Figure 19, a plan; and Figure 23, an end view of
the apparatus complete. Over this frame or apparatus is passed the shade shewn
in Figures 26, 27, 28, and 29, such shade being made of cardboard or other suitable
material and formed with a joint cat each end, and with joints at the corners
which allow of it being folded up, as shewn in edge view at Figure 26.
Having thus described my Invention, and the manner of performing the same, I
wish it to be understood that I do not confine myself to the precise details herein
-laid down-and-shewn- in the Drawing, as- they--may be varied without-departing-
from the peculiar character of my Invention, but what I do claim is,―
Firstly. The construction and employment of the improved regulating burner,
arranged and operating substantially as herein-before described, and represented in
the accompanying Drawing.
Secondly. The improved construction of triangle or gallery, as herein-before
described, and represented in the accompanying Drawing.
Thirdly. The improved construction of coronet, as herein-before described, and
represented in the accompanying Drawing.

In witness whereof, I, the said Oscar Siebert, have hereto set my hand and
seal, this Twenty-sixth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
