page_text: I, LEONARD GEORGE TATE, of 20, Bucklersbury, in the City of London, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:--
This invention consists in an improved wall socket and plug therefor for use
with electrical fittings.
The base of the socket, preferably of poreclain is made with a central cross
bridge of the same material. On each side of the bridge there is fixed to the base
a metal fitting comprising a binding post or screw and a cylindrical or other
sleeve or socket standing perpendicularly to the base. Suitable holes are made
in the base for the passage of the wires to the binding posts or screws and for
the passage of the screws or the like for holding the base in its
place. The cover of the socket is made to enclose the bridge and the metal fittings
and is preferably secured by screws passing through it and engaging in holes in
the bridge. In the cover are two holes aligned with the metal sleeves aforesaid."
The plug carries two metal rods preferably split longitudinally for their better
engagement with the metal sleeves into which they severally pass when the plug
is adapted to the socket.

and is preferably secured by screws passing through it and engaging in holes in
the bridge. In the cover are two holes aligned with the metal sleeves aforesaid.
The plug carries two metal rods preferably split longitudinally for their better
engagement with the metal sleeves into which they severally pass when the plug
is adapted to the socket.
In the annexed drawing:-Fig. 1 is an elevation of the socket and plug inserted
therein. Fig. 2 is a section through these parts on the line 2-2 of Fig. 3.
Fig. 3
is a section on line 3-3 of Fig. 2. The base A is made in one piece with the bridge
or central cross piece Band has in it screw threaded holes for engagement of the screws
a which fasten the metal parts C, other holes al for passage of the wires to the metal
parts C, and other holes a² for the passage of screws for fastening it to the wall.
In the bridge are also screw threaded holes for engagement of screws a³ by which
the cover D is held in place as shown in Fig. 1 and in the cover D are two other
holes for passage of the split contact pins of the plug E.
The metal fittings C are counter parts one of the other and are secured by the
screws a one on each side of the bridge B. Their exact position on the base A is
not material provided the sockets C₁ thereon are alligned with the holes a¹ in the
cover D and the binding posts C are alligned with the holes a'. C³ are screws for
securing the ends of the wires in the binding posts C².
The construction of the plug E is similar. In its body are two passage ways El
for the wires to the two split pins E2. The latter are integral with or fixed in two
metallic plates E3 one on each side of a central bridge and secured by screws E6
to the body of the plug. The split pins E2 are adapted to pass through the holes a
in the cover 1 and engage with friction in the sockets C¹ when the plug is in
electrical connection with the wall socket.
E is a plate preferably of vulcanite or porcelain covering the connections within
the plug it is attached by a screw or screws 17 to the bridge E of the plug.
The base A and cover D) are preferably of porcelain and the body of the plug E
is of wood porcelain or some other material which is non conductive of electricity.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. A wall socket and plug comprising a base having a diagonal bridge or raised
cross piece and metal fitting one on each side of said bridge, each metal fitting com-
prising a socket for reception of a split pin of the plug, a binding post and means
for its attachment to the base, in combination with a cover having holes alligned
with the said sockets and a plug having two split pins for engaging in said sockets
and means for electrical connection of wires to said pins.
2. The construction of wall socket and plug substantially as herein described and
illustrated in the annexed drawings.
