PROVISIONAL SPECIFICATION.
Improvements in Tables for the Game of Billiards, and in Methods
of Adapting the same to be Used also as Dining-tables, and in
other similar Articles of Furniture, the Tops of which are
Required to be Raised and Lowered.
I ARTHUR PAGET Mechanical Engineer of Radunoor Loughborough in the County
of Leicester, do hereby declare the nature of this invention to be as follows :—
The object of this invention is to make improvements in tables for the game of
billiards and in methods of adapting the same to be used also as dining-tables, and
in other similar articles of furniture the tops of which are required to be raisor and
lowered.
The first part of my invention consists of a method of forming very light and strong
tops for tables for billiards by forming them of a cast iron framing or plate with
cement, such as Portland cement or a similar material or similar materials attached
to or around parts of the said frame and held thereto by suitable ribs or bars.
The second part of my invention consists of the arrangement and use of a screw
or screws actuating one, two or more pairs of legs each of such legs being jointed at
one end and each pair of such legs being jointed together at either the centre of their
length (or near thereto) or each leg being jointed at both ends (or near thereto) and
one of each pair of legs being attached to the said screw or screws in such a manner
that when the said screw or screws shall be revolved, the angle between the said pairs
of legs is increased or decreased and the table-top, or seat, or desk, or other similar
article of furniture which the said legs support is lowered or raised.
The third part of my invention consists of the construction and use of a screw
with a peculiarly shaped thread in combination with legs hinged or jointed together
for raising and lowering the tops of billiard-tables or other articles of furniture. The
said screw-thread having one side or face at right angles to its axis and the other side
at a more acute angle to the same. The nut in which the said screw works being
made of what is well known as "anti-friction metal" cast in a suitable mould with
the said screw (or a similar screw) used as a "core" thus avoiding the costly process
of cutting a thread in the said nut.

COMPLETE SPECIFICATION.
Improvements in Tables for the Game of Billiards, and in Methods
of Adapting the same to be Used also as Dining-tables, and in
other similar Articles of Furniture, the Tops of which are
Required to be Raised and Lowered.
ARTHUR PAGET Mechanical Engineer of Radmoor Loughborough in the County
of Leicester 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 :—
The object of this invention is to make improvements in tables for the game of
billiards and in methods of adapting the same to be used also as dining-tables, and
in other similar articles of furniture, the tops of which are required to be raised and
lowered.
The first part of my invention which I will describe consists of a method of forming
very light and strong tops for tables for billiards by forming them of a cast iron
framing or plate with cement, such as Portland cement or a similar material or
Prine S7

page_text: similar materials attached to or around parts of the said frame and held theroto by
suitable ribs or hars.
Figs. 1, 2 and 3 sheets 1 and 2 show this arrangement where Fig. 1 is an
elovation.
Fig. 2 is a part section and Fig. 3 a part plan of such a table, A. A. is the cast
iron framing referred to which is in the form of a light tray the bottom of which is per-
forated with holes some of which are shown at B.B. Figs. 2 and 3 these holes I make
smaller at the top than at the bottom as shown in Fig. 2. This iron framing or tray I cover
with suitable paint, or galvanize or by other suitable means protect from rust. I then
cover this framing or tray with Portland cement or other suitable material or materials in 1
such a manner that it shall fill up all the holes B. B and form a smooth true surface
upon which the cloth can be stretched in any of the ordinary well known manuers.
The cement fills пр the holes B which said holes being larger at the bottom than
at the top cause the cement to he firmly dovetailed or keyed into the cast iron
framing.
In some cases I allow the cement to cover also parts or the whole of the bottom of
the iron framing or tray.
The second part of my invention which I will describe consists of the arrangement
and use of a screw or serews actuating one, two or more pairs of legs each of such
legs being jointed at one end and each pair of such legs being jointed together at
either the centre of their length (or near thereto) or each leg being jointed at both
ends (or near thereto) and one of each pair of legs being attached to the said serow
or screws in such a manner that when the said scrow or screws shall be revolved, the
angle hetween the said pairs of legs is increased or decreased and the table-top, or
seat, or desk, or other similar artiele of furniture which the said legs support is lowered
or raised.
Figs. 1. 2 and 3 sheets 1 and 2 show this arrangement.
Fig.
is a side view of a Billiard table supported by the light legs C. which
may he made of iron or other suitable material. It will be seen that in this drawing
two pairs of legs are shown. The legs are jointed at the top to the table at (and
at the bottom to a shoe or foot C. The bottom ends of the legs are also jointed
to the said shoes or feet (. The top ends of the legs Care jointed to suitable
bars C in which are nuts ( (Fig. 3) which work upon the screw ( which said
screw is made with a right & left hand thread. Thus it will be seen that when the
said screw is turned by the handle C (Fig. 3) the two legs C' are moved nearer
together or further apart and the angle between the legs and is increased or
decreased and the table can thus be raised into the position shown by dotted lines in
Fig. 1 or lowered into the position shown in full lines, at pleasuro. In some casos
instead of jointing the legs CC at their ends to a shoe C I make them so that they
cross, and are jointed to, one another at or near the centre of their length. It will
be evident that legs so arranged can be actuated by a screw in a manner similar to
that above described and the table top to which they are attached can be raised or
lowered at pleasure. I have described this arrangement as applied to a Billiard table
but it is evident that this arrangement can be easily applied to a Table top, or desk,
or seat, or other similar article of furniture.
The third part of my invention which I will describe consists of the construction
and use of a scrow with a peculiarly shaped thread in combination with logs hinged
or jointed together for raising & lowering the tops of billiard-tables or other articles
of furniture. The said screw-thread having one side or face at right angles to its
axis and the other side at a more acute angle to the same. The nut in which the
said screw works being mado of what is well known as "anti-friction metal" cast
in a suitable mould with the said screw (or a similar screw) used as a
"thus
avoiding the costly process of cutting a thread in the said nut. Figs. 4 and 5 sheet 2
show the shape of the screw above referred to.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 desire it to be understood
that I do not confine myself to the exact details heroin set forth as such may be varied or

page_text: modified without departing from the principle thereof but what I claim as my
Improvements in Tables for the game of Billiards and in methods of adapting the
same to be used as dining-tables and in other similar articles of furniture the tops of
which are required to be raised and lowered are :-
First. The method of forming very light and strong tops for tables for billiards by
forming them of a cast iron framing or plate with cement, such as Portland cement
or a similar material or similar materials attached to or around parts of the said
frame and held thereto by suitable ribs or hars substantially as herein before described
with reference to Figs. 1. 2 and 3 sheets 1 and 2.
Second. The arrangement and use of a screw or screws actuating one, two or more
pairs of legs each of such legs being jointed at one end and each pair of such legs
being jointed together at either the centre of their length (or near thereto) or
each leg being jointed at both ends (or near thereto) and one of each pair of
legs being attached to the said screw or screws in such a manner that when the
said screw or screws shall be revolved, the angle between the said pairs of legs is
increased or decreased and the table-top, or seat, or desk, or other similar article of
furniture which the said legs support is lowered or raised substantially as herein
before lescribed with reference to Figs. 1. 2 and 3 sheets 1 and 2.
Third. The construction and use of a screw with a peculiarly shaped thread in
combination with legs hinged or jointed together for raising and lowering the tops of
billiard-tables or other articles of furniture. The said screw-thread having one side
or face at right angles to its axis and the other side at a more acute angle to the same.
The nut in which the said screw works being made of what is well known as
"anti-friction metal" cast in a suitable mould with the said screw (or a similar screw)
used as a " core "thus avoiding the costly process of cutting a thread in the said
nut substantially as herein before described with reference to Figs. 4 and 5 sheet 2.
