PROVISIONAL SPECIFICATION.
Improvements in and connected with Distribution, Connection, or
Terminal Boards for Telephonic Systems.
We, MAX BYNG, Electrical Engineer, and FRANCIS GEORGE BELL, Electrician,
both of 69-71-88, Queen Victoria Street, in the City and County of London, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to certain improvements in and connected with distribu-
tion, connection or terminal boards for telephonic or like systems and has for
its object the provision and arrangement of terminal strips whereby a correspond-
ing wire of a series in a multiple cable may be electrically coupled to its like in
another, or several other cables.
In carrying our invention into practice, we construct a connecting or terminal
board as shown by the appended drawings in which Figure 1 is an elevation,
with the major part of the front removed, and Figure 2 a section thereof,
similar letters of reference indicating corresponding parts in both views.
The framed board A carries a number of transverse insulating bars a a¹ all all
corresponding to the number of multiple cables B B B B, and upon each
bar is arranged terminal screws similarly corresponding to the number of
wires or leads in each cable, the barèd ends of which are thereto attached. Each
terminal screw c makes contact with a vertical contact bar at the back of
the board. In the case illustrated by the drawings there are nine wires to each
of the multiple cables B B B B. Each of these are, as aforesaid, connected
to a terminal screw c and each screw in a vertical line, (shown dotted by Figure 1)
corresponds to a vertical bar d common to all screws c in the same plane. There-
fore each wire of the nine constituting each cable B is coupled to its fellows of
like significance. The bar is a supplementary contact bar which may correspond
to the earth or battery leads.
The essential feature of our said invention is in the arrangement and disposition
or horizontal and vertical connecting bars and terminals therefor, so that with
a number of multiple cables, each separate wire may be coupled to the corre-
sponding ones in its series for distribution or intercommunication systems.

page_text: 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 follow-
ing statement:-
Our invention relates to certain improvements in and connected with distribu-
tion, connection or terminal boards for telephonic or like systems and has for
its object the provision and arrangement of terminal strips whereby a correspond-
ing wire of a series in a multiple cable may be electrically coupled to its like in
another, or several other cables.
In carrying our invention into effect we construct a connecting or terminal
board as shown by the drawings appended to our Provisional Specification, in
which Figure 1 is an elevation with the major part of the front removed, and
Figure 2 is a section thereof, similar letters of reference indicating corresponding
parts in both views.
The framed board A. carries a number of transverse insulating bars a a¹ a¹¹ a¹
corresponding to the number of multiple cables B B B 13, and upon each
bar a is arranged terminal screws c corresponding also to the number of wires
or leads in each cable; the barèd ends of which are thereto attached. Each
terminal screw c passes through the board A, and establishes electrical contact
with vertical contact bars Figure. 2, (shown dotted by Figure 1) these being
preferably placed at the back of the board A. and at right angles or approximately
thereto. In the drawing there are nine wires to each of the multiple
cables B B B B. Each of these are as aforesaid connected to a terminal
screw c, and eacli screw c corresponds to, and makes contact with one of the
vertical bars & common to all the screws in the same plane. Therefore each
wire of the nine, constituting each cable B is coupled to its fellows of like signifi-
cance in the other cables. The bar is a supplementary bar which may be
coupled to the earth or battery leads.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
The arrangement and disposition of connecting bars and terminal screws in,
combination with multiple cables so that each wire may be connected to the
corresponding wire or wires in any other cable or cables in its series for distribu-
tion or intercommunicion telephonic systems, substantially as herein described
and shown by the appended drawings.
