PROVISIONAL SPECIFICATION.
Improved Means for Varying the Elevation of Combined Billiard
and Dining Tables.
I, CHARLES BOARD, of 39, Stokes Croft, Bristol, Billiard Table Maker, do
hereby declare the nature of this invention to be as follows:-
This invention consists in improved means for varying the elevation of combined
billiard and dining tables.
According to this invention a spindle is passed vertically through each leg of
the table and is fitted at the upper end with a chain pulley.
The pulleys are keyed or otherwise rigidly fixed on the spindles which latter are
passed through a suitable bush or bearing provided in the leg.
In contact with the bottom of the bush is a collar formed or fitted on the
spindle. A chain pulley similar to those of the legs is carried. in a bracket
extending under the table from one end thereof. This pulley is capable of being
rotated by means of bevel or mitre gearing operated through a shaft extending
outwards to the end of the table and arranged to be turned by a key or handle.
At the opposite end of the table is another chain pulley adjustably carried in a
bracket below the table.
An endless chain is conducted around the whole series of pulleys. The spindles
of the table legs are screw-threaded towards their lower ends which work in
sockets extending upwards from the floor and serving as feet.
By applying the key or handle to the shaft of the chain pulley at the operating
end of the table, the whole of the pulleys are turned simultaneously and to the
same extent. Accordingly, the table is raised or lowered uniformly throughout.
The pulley opposite to the operating end of the table is adjusted, when required,
in its bracket so as to maintain a proper degree of tension on the chain.
In tables having more than four legs intermediate chain pulleys are disposed
under the table to keep the chains in gear with the pulleys of the leg spindles.

COMPLETE SPECIFICATION.
Improved Means for Varying the Elevation of Combined Billiard
and Dining Tables.
I, CHARLES BOARD, of 39 Stokes Croft, Bristol, Billiard Table Maker 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 consists in improved means for varying the elevation of combined
billiard and dining tables.
According to this invention and referring to Figs. 1 & 2 a spindle (A) made of
iron or other suitable material is passed vertically through each leg of the table
and is provided at the top with a chain wheel (B) secured to the spindle by a key
or other suitable means. A collar (C) formed on or secured to the spindle (A)
fits against the lower side of a suitable bush or bearing (D) which is bolted or
screwed to the top of each table leg and takes the weight of the table. The
[Price 8d 1

page_text: The
lower end of the spindle (A) is screw threaded and works in a socket (E) made
of brass or other suitable metal which extends upwards from the floor.
outside of this socket (E) is turned parallel and acts as a guide for the collar (F)
which is secured to the bottom of the table leg, and which slides on the socket (E).
A bracket (G) carrying a chain wheel (H) similar to (B), and which is rotated
by means of a pair of bevel wheels (J) and spindle (K) extending outwards from
.the table and to which a suitable key or handle (L) is fitted, is fastened to one
end of the table. At the opposite end of the table is another bracket carrying a
similar chain wheel adjustable for taking up the slack of the pitch chain by means
of a bolt and nut working in a slot. An endless pitch chain passes round the
whole series of chain wheels. By turning the handle (L) the chain wheels are
rotated by means of the pitch chain and the spindles turned in the sockets (E)
thus raising or lowering the table.
I sometimes dispense with the adjusting bracket and arrange the first mentioned
bracket to slide inwards to take up the slack of the chain.
I sometimes arrange the socket (E) to extend upwards from the floor high
enough to work with the spindle (A) screwed at its upper end.
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 ;-
The combination of a pitch chain, chain wheels, screwed spindles and sockets
for the purpose of raising and lowering combined billiard and dining tables,
substantially as set forth in the Specification and particularly shown in
Figures 1 & 2.
Dated this 29th day of October Eighteen hundred and Ninety-four.
