Improvements in Electrical connections for Tables and the like.
OSCAR THOMAS BANKS, Electrical Engineer, 21, Wingfield Road, Walthamstow,
Essex, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide improved means of applying electric
current to dining tables for decoration and illuminating purposes, as hereinafter
described. In carrying the said invention into practice I purpose arranging two
sockets or cushions and inserted in the top of tables or sideboards or on seperate
leaf to be used in dining tables in the ordinary way, one to be for the positive and
one for negative pole and may be formed in the following manner in each case.
The top of the table or leaf is drilled with two different size holes or recesses the
first one about 1½ inches diameter and or 4 inches deep. The second recess
about 1 inches diameter and any suitable depth. The bottom of the first recess
will then form a shoulder into which is inserted a ring of brass or other suitable
conductor, with a piece of gauze wire underneath or on top of ring through which
the needle connections pass, to make contact to the various fittings to be lighted,
and connected by flexible cords or flat strips as desired. Over the brass ring or
gauze wire I fix a peice sheet indiarubber which is held firmly in place by an
insullating ring or cover the object being to protect the same from a short circuit
in the case of water, wine, or other liquids being spilt between the two poles and will
appear when fitted as two rings one inside the other, the outside being of insullating
material and the inside ring of metal with gauze centre covered with indiarubber.
The metallic ring is connected with a long screw and loose nut under top of table
for connecting the supply of electric energy by flexible cord the second recess, is
fitted with cork or small shot as may be found best in practice so as to keep the
needles connecting the fittings in contact during the vibration of the table while in
use. It may be found that the small shot will answer without the employment of
gauze wire fitted in the first recess and the shot covered with insullating and
metallic rings, as already described.

OSCAR THOMAS BANKS, 21, Wingfield Road, Walthamstow, Essex, Electrical
Engineer, 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 has for its object to provide improved means of applying electric

page_text: connections commonly known as plug or wall sockets for dining-room tables floors
or wall connections as hereinafter described.
The socket or cushion part which is usually fixed or let flush into tables, floors,
or other places found suitable as required and the pin plug or needle connection
joined to a flexible cord wire to any required fitting or ornament and may be used
for decoration or illuminating purposes as desired.
The socket or cushion may be made with each pole seperate or combined as shewa
in the accompaned drawings as found suitable for the purpose for which it is
applied. Fig. 1 is an elevation of a double pole socket or cushion and may have a
protection fuse connected on one or both poles as shewn in Fig. 2 and 3. Fig. 2 is
a section on line A¹, B', which is a plan of Fig. 2,-A being a box with a partition
in centre deviding the poles and made of volconnite porcelain, glass, wood or any
suitable non conductor E being a thin layer of cork, gauze wire or other material
a thin layer of indiarubber. The purpose of these being to keep the small shot
from falling out of the box and form a cover to same combined with B which screws
or forces tightly on. The screw H' is for the positive connection H³ for the negative.
The screw G is connected with the shot inside the box A and joined by J which is
the fuse to connect the circuit from H¹ & H to the screw G. The screw connecting
may be arranged at the bottom of box A as in Fig. 3. K is a cover or case covering
the connections where these are used in damp places or for protection but
is not substanially requisite. Fig. 3 shows a socket or cushion connection
which might be used for tables and the like which is single pole A being a box as
already described B cap or cover combined with EFE and be made by having two
layers of cork with indiarubber inserted between or rubber and cork underneath
the object being to keep any liquid from entering the interior to form a short circuit
when the two poles are fixed closely together or side by side. 1 small shot H'
connecting current to fuse J and screw G to shot inside of box Fig. 4 shows elevation
of Fig. 3.
Fig. 5 shows a two pin or needle connection as described connecting the fitting
or ornament and may be made of any size to suit requiments and non conducting
material desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare what I
claim is:-
1 The small lead or metallic shot inside of box A to make connection or contact.
2. The cover with indairubber and cork or gauze combination as described.
