Year: 1871

page_text: LETTERS PATENT to George Wright, of 162, Westminster Bridge
Road, in the County of Surrey, Upholsterer, for the Invention of
"IMPROVEMENTS IN BILLIARD TABLES, APPLICABLE ALSO TO OTHER TABLES OB
SURFACES REQUIRING ADJUSTMENT.'
"
Sealed the 8th December 1871, and dated the 12th June 1871.
PROVISIONAL SPECIFICATION left by the said George Wright at the
Office of the Commissioners of Patents, with his Petition, on the
12th June 1871.
I, GEORGE WRIGHT, of 162, Westminster Bridge Road, in the County
of Surrey, Upholsterer, do hereby declare the nature of the said 'Inven-
tion for "IMPROVEMENTS IN BILLIARD TABLES, APPLICABLE ALSO TO OTHER TABLES
OR SURFACES REQUIRING ADJUSTMENT," to be as follows:-
My Invention relates to means of altering and adjusting the level of
billiard and other tables or surfaces by means of mechanism in the legs
thereof, which I will now describe.

page_text: Each leg is made in two parts, the upper part being framed to the
table, and the lower part having its upper end circular or polygonal in
section, fitted to slide in a cavity formed in the upper part. In the
upper part I mount a vertical spindle in a bearing, in which it can turn
freely, with collars to prevent it from moving up or down. The lower
part of this spindle has a screw thread cut on it, which works in a nut
fixed in the lower part of the leg. On the top of the spindle a bevil
wheel is fixed, and another bevil wheel gears into it, the spindle of the
latter wheel passing into a hole in the side of the upper part of the leg.
A key or handle can be inserted into this hole to turn the bevil wheel,
and thereby to turn the screwed spindle, which causes the upper part
of the leg to rise or descend according as the handle is turned in the
one direction or the other. Sometimes I connect the bevil wheels of
the several legs of the table by means of horizontal spindles and other
bevil wheels, so that on turning one of them the others so connected
with it are turned at the same time, and thus the whole table can be
made to rise or descend at once.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Wright in the Great Seal Patent Office
on the 11th December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WRIGHT, of 162, Westminster Bridge Road, in the County of Surrey,
Upholsterer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent,. bearing date the Twelfth day of June, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Wright, Her special licence that
I, the said George Wright, my executors, administrators, and assigns;
or such others as I, the said George Wright, my executors, adminis-*
trators, and assigns, should at, any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,

framing 6 of a billiard table to which my Invention is applied;
Figure 2 represents a sectional plan, to a larger scale, of one of the
legs a¹; and Figure 3 represents a vertical section of the leg a¹.
The upper part of the leg is a box c containing the bevil gearing; and
having a cylindrical pieced projecting downwards into a socket e formed
in the lower part of the leg, in which socket it is fitted to slide. The
wooden framing of the table b is secured to the box c by bolts ƒ, f. A
vertical screw g is mounted in a bearing in the box c with a collar under.
the bearing, and passes through the bottom of the socket e, which forms
a nut for it. On the upper end of the screw g is fixed a bevil wheel h,
and a bevil pinion & gearing with the wheel is fixed on a spindle Z,
which is mounted in bearings in the side of the box c. On turning the
spindle by a suitable key or handle the screw g is caused to revolve,
and thus the box c is caused to ascend or to descend according to the
direction in which the spindle is turned, the cylindrical projection à
sliding upwards or downwards in the socket e, and thus serving as a
guide. When it is desired that the whole table should ascend or
descend, the spindles on which the bevil pinions are fixed are extended
from leg to leg, as represented in Figure 1, so that on turning the one
spindle by a key or handle the others turn with it, and thus the screws
of all the legs are turned simultaneously. For a billiard or other table
or surface requiring adjustment I find this the most convenient arrange-
ment, as each leg can by turning its lower part be first adjusted to the
floor or ground on which it stands, so as to level or adjust the table,
and afterwards when all the screws are turned simultaneously, as above
described, the whole table in ascending or descending maintains its level
or adjustment.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I claim, the use of mechanism,
of waltoning and

adjustment of a similar kind.
In witness whereof, I, the said George Wright, have hereunto set
my hand and seal, this Eleventh day of December, in the year of
our Lord One thousand eight hundred and seventy-one.
