Improvements in and relating to Tables.
We, ANDREW THOMSON, Senior, ANDREW THOMSON, Junior, and JAMES
SLATER THOMSON, all of the Firm of A. Thomson & Sons, Port Eglinton Cabinet
Works, 9 Ritchie Street, in the City and County of Glasgow, do hereby declare
the nature of our invention to be as follows:-
This invention has reference to improvements in and relating to tables, and
essentially comprises the constructing of a table which shall possess the properties
of a "Pembroke or folding leaf table and be easily convertible into a telescopic
or extensible table, and vice versa.
"
And in order that our said invention and the manner of performing or carrying
the same into effect or practice may be properly understood we have hereunto
appended an explanatory sheet of drawings in which the same reference letters are
used to indicate corresponding parts in all the figures where shown.
Figure 1 is a perspective elevation of a table as constructed in accordance with
our improvements illustrating the hinged side leaves as folded or hanging down, as
a Pembroke table, and showing the portable centre parts projecting out from the
housing underneath.
Figure 2 is a similar view to Figure 1 but showing the table with the side leaves
as supported up, and the portable centre parts in active position to convert the
table into a telescopic or extended position.
Figure 3 is an inverted plan view of the table showing one side leaf as folded
up, and
Figure 4 is a transverse section as taken on the line 3-3 of Figure 3.
As shown on these drawings, our improvements consist in forming the centre
body of the table in two main parts A, A, which meet together at the centre A³
in the Pembroke position of the table. Each of the longitudinal side leaves of
the table are formed in two parts a a¹ and are respectively hinged or connected
at a to the side edges of the centre parts A A'; and ribs a are formed on the
under surface of each of these parts a a¹ to pass each at the joint and act as a
support when the leaves are folded up. In the folded up position these flap or
leaf parts a a' are supported by swivelling out hinged radial brackets a one pair
of these being hinged to the frame B and the other pair of these being hinged to
blocks a attached to the table legs D¹; while in the hanging down position of
these flaps the brackets a³ are swivelled in parallel with the longitudinal sides of
the table.
The table tops A a A' a¹ are respectively carried on side frames B. B¹ with
transverse stays B B and when the table is to be converted from the one position
to the other these frames and table tops are operated by a screw threaded rod C
carried in bearings and operated at the end C' by a hand screw key in the usual
manner that telescopic tables are operated. Tongues or beads are formed at bb¹
in the side frames B B' to work in recesses c c¹ formed respectively in each frame
so that these frames may slide and be guided parallel and adjacent to each other
when being moved along by the extending screw rod C. Legs D. D' are fitted to
the frames BB' respectively with rollers or castors on their lower end for
supporting and moving the parts A. A¹ of table.
In the Pembroke position of the table the extensible transverse leaves or
boards E. E. which are formed in length equal to the width of the combined centre
top A or A' and wings a or a' on both sides, and which may be one, two, or more

page_text: in number are portably housed on bracket shelves E' underneath the table, as
shown in Figures 1 and 4. But when the table is to be converted into a telescopic
or extensible table these leaves E are removed from underneath the table, and the
screw C turned to place the parts A and A' sufficiently asunder to take in the
required number of leaves E between them and which would have dowel pins e to enter
holes or recesses el in the centre tops A. A' and side flaps a a¹ and in their adjacent
edges respectively, and vice versa; and the screw rod Ċ would then be turned to
bring the parts A. A' in close contact with the adjacent leaves E. The flaps a a'
on each side of the centre table tops A A' would be raised and supported by the
swivelling brackets a³, and the table would be ready for use in the position shown
in Figure 2.
Sliding drawers F may be formed at the ends of the table.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The constructing of a table which will possess the properties of a Pembroke
or folding side leaf table, and be easily convertible into a telescopic or extensible
table, and vice versa, substantially as herein described in reference to and shown in
the accompanying drawings.
2. In tables, the forming of the top covers with their side carrying frames in
two main moveable parts and the hinging or connecting of the side leaves or flaps
independently to each of these parts respectively so as to be convertible into
Pembroke and telescopic or extensible tables when the centre transverse leaves are
removed or inserted respectively, substantially as herein described in reference to
and shown in the accompanying drawings.
