PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Keeping Billiard
Table Cushions at a More Uniform Temperature.
I, FRANK GALLSWORTHY, of Wellington Street, 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 billiard tables and relates to
certain improvements to the method of lighting described in my Specification of
Letters Patent No. 9904 dated 22nd May 1894 and has for its object the com-
bination with the cushion and lighting table therein described of an additional tube
80 arranged that the heat from the lighting tubes can be regulated so that the
temperature of the cushion can be maintained uniform..
I accomplish my object in the following manner. The lighting tubes containing
the filament are enclosed in a recess formed in the cushion foundation and supported
in any suitable manuer. Above and partially enclosing the lighting tubes I place
a hollow jacket made of suitable material and constructed concave on the side next
the lighting tubes. A current of water is caused to pass through the jacket which
absorbs to a considérable extent the heat given off by the incandescent lights
before it gets to the cushion or cushion foundation, thus regulating the heat in the
recess formed in, the cavity around the table and under the cushion, thereby
preserving, the latter by keeping it at a uniform temperature.
When the lights are not being used, the water circulating in the jackets may be
warmed by any suitable means in order to keep up the uniform temperature.

Improvements in the Method of and Apparatus for Keeping Billiard
Table Cushions at a More Uniform Temperature.
I, FRANK GALLSWORTHY, of Wellington Street, 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 billiard tables and relates to
certain improvements to the method of lighting described in my Specification of
Letters Patent No. 9904 May 22nd 1894, and has for its object, the combination
with the cushion and lighting table therein described of an additional tube so
arranged that the heat from the lighting tubes can be regulated so that the
temperature of the cushion can be maintained more uniform.
I accomplish my object in the following manner. The lighting tubes containing
the filament are enclosed in a recess formed in the cushion foundation and supported
any suitable manner. Above and partially enclosing the lighting tubes I place

page_text: a hollow jacket made of suitable material and constructed concave on the side next
the lighting tubes. A current of water is caused to pass through the jacket
which absorbs to a considerable extent the heat given off by the incandescent
lights before it gets to the cushion or cushion foundation, thus regulating the heat
in the cavity around the table and under the cushion, thereby preserving the latter
by keeping it at a more uniform temperature.
In order that my invention may be fully understood, I will describe the same
more in detail by making reference to the accompanying drawings in which
Fig. 1 represents a cross section through a billiard table cushion constructed to
receive my improvement which is.added thereto.
Fig. 2 is a section of same through line a..b.
The table T. is of the ordinary description covered with cloth, and the sides of
the table are prepared with cushions, the foundation of which is indicated by G.
and is supported or attached to the table in any convenient manner, the said
foundation is faced with india rubber or other suitable material H. in the ordinary
manner.
An open space I. 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 lamp tubes J. which may be held in the required position in any
convenient manner.
The light from the lamp tubes is roflected through the open space I. on to the
table T. by a reflector K. placed behind the lamp tubes J. and by the use of
shades S. placed in convenient positions between the light and table, the light is
thus diffused and subdued.
In order to prevent the heat from the lamps having a detrimental effect on the
cushions, 1 secure above the lighting tubes or lamps J. a curved pipe N. made of
light material and constructed convex on the upper or outer circumference, and
concave on the other or the side next the lighting tube, or the pipe N. may be of
a section somewhat similar to sectional detail Fig. 3.
A current of water is passed through the said pipe N. which to a considerable
extent absorbs the heat given off by the incandescent light before it gets to the
cushion foundation, thus reducing the heat in the cavity R. around the table and
under the cushions, thereby preserving the latter by keeping the temperature under
more perfect control.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is,
1. The combination of the lamps J. and pipe N. with the cushion of a billiard
table arranged substantially in the manner and for the purpose as hereinbefore set
forth.
2. A billiard table provided with lamps J. and pipes N. placed beneath the
cushion, substantially in the manner and for the purpose as hereinbefore set
forth.
