PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Billiard-table Cushions.
I, GEORGE DAVISON STEVENS, Manager to the firm of Thurston & Company,
Billiard Table Manufacturers, of 16, Catherine Street, in the County of Middlesex,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improved means for backing and supporting the elastic
facings of billiard-table cushions, whereby their action is improved.
I am aware that it has been proposed to back cushions with steel plates bolted
to the slate bed and to secure the elastic facings thereto; but such plates are
objectionable in consequence of their liability to rust, and because they expand
and contract to an excessive extent under the influence of the considerable
variations of temperature to which billiard tables are exposed.
The elastic facing of a billiard-table cushion backed and supported according to
my improved method is mounted in a wooden carrier in the usual manner and
backed by a bar of slate or similar non-metallic substance. These parts are or
may be fastened to the rail, which is recessed for the purpose, and the latter is
secured to the slate bed of the table in the usual or any convenient manner.
bar of slate is preferably rectangular in cross section, and may if desired be
extended downwards to the full depth of the slate bed or thereabouts.
The
Instead of forming the carrier for the elastic facing in wood, slate may be
employed; and the carrier may if preferred be formed in one with the backing bar
previously referred to.
Owing to the rigidity and the inertia of the bar of slate or similar substance, the
elastic facing of the cushion is better supported and the action thereof improved.
Liability to rust is also avoided, and difficulties arising from the excessive expansion
and contraction of metal are obviated.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Billiard-table Cushions.
I, GEORGE DAVISON STEVENS, Manager to the firm of Thurston & Company.
Billiard Table Manufacturers, of 16, Catherine Street, in the County of Middlesex,
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 improved means for backing and supporting the elastic
facings of billiard-table cushions, whereby their action is improved.
I am aware that it has been proposed to back cushious with steel plates bolted
to the slate bed and to secure the elastic facings thereto; but such plates are
objectionable in consequence of their liability to rust, and because they expand
and contract to an excessive extent under the influence of the considerable variations
of temperature to which billiard tables are exposed.
The accompanying drawing shews, in vertical section, part of a billiard table
embodying my invention.
The elastic facing A of a billiard-table cushion backed and supported according
to my improved method is mounted in a wooden carrier B B' in the usual manner,

page_text: and backed by a bar C of slate or similar non-metallic substance. These parts are
or may be fastened to the cushion-rail D, which is recessed for the purpose, and
the latter is secured to the slate bed E of the table in the usual or any convenient
manner. The bar C is preferably Fectangular in cross section, and may if desired
be extended downwards below the slate bed, as shewn. F is a wood slip to which
the cloth is fastened; G being the wood frame of the table. H is one of the bolts
which secure the cushion-rail D and the bar or block C to the slate bed E;
H' being the steel nut into which the bolt screws.
Instead of forming the carrier B B' for the elastic facing in wood, slate may be
employed; and the carrier may, if preferred, be formed in one with the backing
bar C.
Owing to the rigidity and the inertia of the bar C of slate or similar substance,
the elastic facing A of the cushion is better supported and the action thereof
improved. Liability to rust is also avoided, and difficulties arising from the
excessive expansion and contraction of metal are obviated.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
1. A billiard-table cushion comprising an elastic facing backed by a bar of slate
or similar non-metallic material, substantially as herein described.
2. In a billiard-table cushion, the employment of a bar of slate or similar non-
metallic material, substantially as and for the purposes herein set forth.
