PROVISIONAL SPECIFICATION.
Improvements in the Method of Lighting Billiard Tables.
I, FRANK GALLSWORTHY of 5 Meadow Lane, Leeds, in the County of York,
Hide and Leather Factor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in the method of lighting billiard
tables.
Hitherto the lights are suspended over the table, to the disadvantage of the
player. My object is to light the table in such a manner as to give a well diffused
light over the surface of the cloth and avoid the inconvenience of the suspended
lights.
I accomplish my object by placing incandescent lights in specially prepared
cushions. The lights may be ordinary incandescent lamps, or a continuous platinum
wire or carbon filament inclosed in tubes in vacuo.
The light is thrown forward on to the cloth by reflectors behind, and by the use
of shades in front of the light, the same is diffused and subdued in order not to
interfere with the player when making his strokes.
In either, the case of the lamps or the continuous platinum wire or carbon
filaments incased in tubes in vacuo, the light issues from between the upper part of
the cushion and the cloth.

Improvements in the Method of Lighting Billiard Tables.
I, FRANK GALLSWORTHY of 5, Meadow Lane, Leeds, in the County of York,
Hide and Leather Factor, 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 certain improvements in the method of lighting billiard
tables.
Hitherto the lights have been suspended over the table, to the disadvantage of
the player. My object is to light the table in such a manner as to give a well
diffused light over the surface of the cloth and the balls, which have hitherto been
lighted from the top, and as a consequence, the under hemisphere of the balls have
been in shadow; and avoid the inconvenience of the suspended lights.
I accomplish my ohject by placing incandescent lights in specially prepared
cushions. The lights may be a series of ordinary incandescent lamps, or a
continuous platinum wire or carbon filament inclosed in tubes in vacuo..
In describing my invention in detail, reference is made to the accompanying
drawings in which
Fig. 1 represents a section through line a. b. of the cushion at the edge or side
of table.

page_text: Fig. 2 is a similar section but through line c. d.
Fig. 3 is a sectional elevation through line e. f. in Fig. 1 showing a method of
attaching the lamps to the cushions, and
Fig. 4 is a similar sectional elevation drawn to a smaller scale showing lamps
suspended at both ends.
The table T. is of the ordinary description covered with cloth, and the sides of
the table are provided with specially prepared cushions, the foundation of which is
indicated by G. supported in any convenient manner and faced with india rubber
or other suitable elastic material at H. An open space 1. is left between the upper
surface of the table T. and the said cushion extending the whole or for the greater
portion round the table, and a cavity R. is formed in the before mentioned
foundation G. for the reception and securing of the lamps J. which may be held in
position by a series of clips L. to which the circuit wires W. may be attached and
the circuit.completed by connecting thereto the platinum wire or carbon filament P.
passing through the lamps J. in vacuo.
The lamps are placed in the cavity and the light reflected through the open
space I. with a reflector K. placed behind the light in order to throw the light
forward on to the surface of the table T. by the reflectors K. and by the use of
Bhades S. placed in the most convenient position between the light and the table,
the light is thus diffused and subdued in order not to interfere with the player when
making the strokes.
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. The lighting of a billiard table substantially in the manner as herein before
set forth.
2. The specially prepared foundation G. and cushion H. with open space I. in a
billiard table as and for the purpose as herein set forth.
Dated this 21st day of February 1895.
