Improvements in Pendants and Brackets for Incandescent Gas
Burners, specially applicable to Gas Pendants and Brackets
for Billiard Tables.
We, ARTHUR CHARLES THOMAS, of 7, Highfield Square, Book-keeper, and
JOSEPH EDWARD ATKINSON, of 48, Derwent Road, Miller, both of Stoneycroft,
Liverpool, in the County of Lancaster, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to gas pendants and brackets chiefly intended for incan-
descent gas burners, and specially adapted for illuminating billiard tables, the
object being to provide a pendant or bracket which casts no shadow on the table, and
which elastically supports the burner, so as to prevent the transmission of sudden
shocks to the mantle of the incandescent gas burner.
We will describe our invention as applied to a billiard table, although of course
it is applicable to other purposes.
We provide a double pendant or bracket of the usual inverted T shape, the gas
being led through the pipes forming the T; in the angles of the Ta scroll work
of, say, wrought iron is fixed and from this scroll work an arm projects, from the
end of which the gas burner and shade are suspended by elastic devices which will
be described hereinafter, and the gas is led to the burner from the bracket by
means of a rubber pipe.
The shade, which is preferably of square pyramidal configuration is carried
from the end of the arm, and may be suspended by rubber strips, spiral springs
or other elastic means, so that when accidentally struck, say with a billiard cue,
the force of the blow is absorbed by the elastic support.
The gas is led to the burner over the top of the shade, so that the latter is not
slit as usual, and there is consequently no loss of light or production of cross light
such as results when the shade is slit. The down pipe to the burner is kept as
close as is practicable to the burner, so as to avoid as far as possible a sharp shadow
being produced.
The elastic device for suspending the burner from the arm is as follows:-
The burner is attached to the arm by one or more bolts and rubber sleeves, the
rubber sleeves being interposed so that either the palm on the tube of the burner
or the palm on the arm, as the case may be, is in contact only with the rubber
sleeves, the bolt passing concentrically through the sleeves without being in contact
with them. The preferred arrangement of the elastic connection in the case of
a bracket for a billiard table is as follows:-
:-
A double palm is formed on the metal pipe connected to the burner, and a similar
palm is formed on the arm, the holes in the palms, which are larger in diameter than
the bolts, being on opposite sides of the pipe and the arm respectively. Two com-
paratively long bolts are passed through the holes in the palm on the arm, then
two fairly long rubber sleeves are threaded on the bolts; the bore of these sleeves

page_text: is larger in diameter than the bolts and the sleeves are held concentrically with
the bolts by flanges or other means; the palmi on the pipe is now threaded on,
and a second pair of sleeves are threaded below this palm, and the arrangement is
screwed up by nuts and washers, the latter bearing on the last mentioned rubber
sleeves. It will be seen that this connection forms an elastic fulcrum for the burner
and its pipe, and that the end of the pipe is connected elastically to the bracket by
the rubber pipe mentioned.
The positions of the two palms mentioned may, of course, be interchanged, and
instead of two bolts there may be but one, or in some cases there may be more than
two. The number of sleeves may also be increased where extra elasticity is
required.
The top of the shade may be covered with a porcelain or opal reflector provided
with holes for the chimney of the burner and the down pipe.

Improvements in Pendants and Brackets for Incandescent Gas
Burners, specially applicable to Gas Pendants and Brackets
for Billiard Tables.
We, ARTHUR CHARLES THOMAS, formerly of 7, Highfield Square, Stoneycroft,
Book-keeper, but now of 17, Woburn Hill, and JOSEPH EDWARD ATKINSON, of
48, Derwent Road, Stoneycroft, Miller, both of Liverpool, in the County of Lan-
caster, 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 gas brackets chiefly intended for incandescent gas
burners, and specially adapted for use for illuminating billiard tables, the object
being to provide a bracket which casts no shadow on the table, and which elastically
supports the burner so as to prevent the transmission of sudden shocks to the
mantle of the incandescent gas burner.
We will describe our invention as applied to a billiard table, although of course
it is applicable to other purposes.
In the accompanying drawings Fig. I, is an elevation of one end of a double
bracket; Fig. II a plan; Fig. III an elevation of the elastic device; Fig. IV a
plan, partly in section on the line A, A, of Fig. III; and Fig. V a fragmentary
section on the line B, B, of Fig. IV.
Throughout the drawings the same parts are indicated by the same reference
figures, and in the case of sections, the direction in which they are viewed is
indicated by the small arrows placed adjacent to the letters denoting the plane of
section.
We provide a double bracket 1 of the usual inverted T shape, the gas being led
through the pipe forming the bracket, and the angles of the bracket being
ornamented by wrought iron scroll work, not shown in the drawings.
From the scroll work, or from the turned up end of the pipe which forms the T
bracket 1, we carry a fixed arm 2 which may either be single, or divided laterally
so as to afford a steadier support for the shade 3, as shown in the drawings, and
strengthened by struts such as 2¹.

page_text: The shade 3, which is preferably of square pyramidal configuration, is suspended
rom the arm 2 by means of clips 4, and may be formed of sheets of opal glass
carried in a suitable metal frame-work; the clips 4 may be elastic so that in event
of the shade being accidentally struck, say with a billiard cue, the force of the
blow is absorbed by the elastic supports.
The gas is led to the burner 5 over the top of the shade; the latter does not
therefore require to be slit as usual, and there is consequently no loss of light, or
production of cross light, such as results when the shade is slit. The burner 5 is
preferably of the incandescent type and the down pipe 6 is kept as close as is
practicable to the burner, so as to avoid any sharp shadow being produced.
The elastic device for supporting the burner from the arm 2 is as follows:-
A palm such as 7 is attached to the gas pipe S which pipe is connected to the gas
supply by a rubber tube 9 and leads the gas to the down pipe 6, and a similar palm 10
is attached to the cross arm 2 of the divided arm 2; each of the palms has four
holes which are larger in diameter than the bolts 11 which pass through them and
which are disposed in pairs on opposite sides of the pipe S and the arm 21 re-
spectively. The two palms are connected together, as shown clearly in Figs. III,
IV and V, by rubber sleeves 12 and 13 whose bore is larger in diameter than the
bolts 11 which are passed through them, and by which they are compressed when
the nuts of the bolts are screwed up. The sleeves are maintained in position
as shown in Fig. V, and washers
laterally by raised flanges 14 formed on the palms
provided with similar flanges are interposed between the bolt heads and the
sleeves 13.
It will be seen that the palm 7 is thus elastically carried from the palm 10 by
means of the compressed sleeves, and that neither the palm 7 nor any of the bolts
are in contact with the palm 10.
The palm 10 is connected to the cross arm 211 by means of lugs 15 and may be
soldered, brazed, or otherwise attached thereto.
The device described forms an elastic fulcrum for the burner and its pipe, and
as the only other connection between the burner and the bracket is the flexible
tube 9, it will be seen that sudden shocks, which are so detrimental to incandescent
mantles, will not be transmitted from the bracket to the burner.
The positions of the two palms may be interchanged, and there may be but two
bolts, or only one bolt, in place of the four as described. The number of sleeves
5 may also be increased where additional elasticity is required.
The top of the shade may be provided with an opal glass reflector provided with
holes tor the chimney of the burner and the down pipe.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
0 claim is:-
