Specification Accepted, 19th Apr., 1887.
GEORGE JOHN PANZETTA 16 Great Chapel Street Oxford Street London Gas Fitter
and Brass Finisher 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 :-
by gas
The object of my Invention is an "Improvement in the lighting of Billiard Tables
the Improvement being to situate two burners within a shade so that,-
1st. The light is reflected along instead of partly over the side of the table.
2nd. By the position of the burners more light is obtained from them than there
would be if placed in the usual horizontal position.
3rd. In case of an undue pressure of gas the direction of the flames will secure the
shades from being burned.
4th. The shadows thrown from the tubes which support the burners are dispersed
before reaching the table.
I situate the burners within the shade to obtain the above results by the use of an
improved burner bracket, which is shown asi n actual use in Fig. 1, in accompanying
drawing. (Fig. 2 shows the actual size of burner bracket for use in ordinary shades.)
The arins of this bracket with the burner sockets attached extend half way across the
shade and the burners are placed so that the flat parts of the flames incline towards
each other, but do not touch. The flat parts of the flames are then opposite those
parts of the shade which reflect the light along the table.
The description of my improved burner bracket Fig. 2 is as follows.―
A. is a socket which screws on to the gasalier and which supports the shade by a
projecting stud.
B. B. are two tubes which are joined together and issue from A. as a single piece.
They are bent down in the manner shown so that no shadows may be cast from the
back part of the bracket; and extend apart to the required distance.
C. C. are two sockets which screw on to the two tubes B. B and hold the
burners D D.

page_text: These sockets are placed so that the flames E. E. from the burners incline towards
each other. The burners D. D. are screwed in the sockets C. C. so that the flat parts
of the flames are towards each other.
Fig. 4 is merely to show that the burners screw into the sockets at right angles to
the end part of the bent tubes.
A is the end part of the bent tube.
B is the socket.
C is the burner.
Fig. 5 is to show the distance which the sockets are kept apart and also the angle at
which the burners are inclined towards cach other.
Fig. 3 is an ordinary single burner bracket and is drawn for comparison between
it and my improved bracket Fig. 2.
This burner bracket may be made of brass or any other suitable metal. The two
tubes may be soldered or brazed together so as to issue from the socket A in Fig. 2
as a single piece, or if desired the two tubes might be made to issue from the socket
separately.
The tubes should be screwed to fit the socket A and also for the burner sockets C. C.
Fig. 2. The two burner sockets are made to screw on the tubes and for the burners
to screw into.
The size of the bracket; the bending of the tubes and the position of the sockets
to be as shown in Figures 2, 4, & 5.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is that by
the use of my
improved burner bracket to be used for the lighting of billiard
tables" the following advantages are obtained.―
::
1st. The light is reflected along the table.
2nd. That the position of the burners allows them to burn better than in the usual
flat position.
3rd. By the situation of the burners the shades are securo from being burned.
4th. That there is an absence of shadows.
5th. That the bent tubes with the sockets attached can be adapted to the sockets of
ordinary burner brackets now in use.
But take notice, I do not claim the Invention of the whole of this bracket, neither
do I claim the use of two burners screwed to bent arms, but claim only the improved
manner of bending lengthening and extending apart of the tubes and the addition of
the sockets in the manner which I have previously described to obtain the advantages
above claimed.
