Improvements in Electric Wire and Pole Connectors.
I, CHRISTEN REES BONNE, of No. 41 Eastcheap, London E.C., Patent Agent 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:-
Our invention refers to improvements in electric wire and pole connectors and bas
for its object to provide a contrivance capable of attaching with a single screw several
wires at once whether of like or varying stoutness.
The manner in which we prefer to carry our invention into effect is shewn by the
accompanying drawings, which are longitudinal sections through the apparatus
according to our invention.
The main body P which may be of any convenient shape and which may be made
of any suitable material for instance brass, and which is hollowed out, part of which
hollowing is cylindrical and part conical. One, two or more slits s, are made in the
main body P so that wires may be passed crosswise into or through the apparatus. A
conically shaped or partly conically and partly cylindrically shaped body p is inserted
in the hollow o and connected with a male screw S by means of a ball and socket
joint k. The said male-screw works in the nut b, which closes up the hollow and is
kept fastened by means of a set screw t.
It will be seen that when the screw S is screwed inward it pushes the cone p deeper
into the hollow so that a wire inserted in the slit s will ultimately become jammed
between the outside of the cone p and the wall of the hollow o, and it will likewise be
seen that several independant wires may be thus jammed at one time, and on account
of the cone p being hung in a ball and socket joint k and as there is sufficient play for
the cone itself it may be brought in an excentric position with respect to the hollow
and consequently wires of differing stoutness may become jammed as described.

Figs. 2 and 3 are modifications upon the construction shewn in Fig. 2 from which
they differ by the hollowing o being cylindrical in its entire length and the slits s
(Fig. 2) being paralel with each other while in Fig. 3 the slits s are made in various
sizes, enabling the very smallest wires to be inserted where they may be most readily
jammed.
It is evident that the hollowing o as well as the conical body p need not be circular
sectionally but might be rectangular, hexagonal, ellipsical etcetera without altering
the principle of our invention, but we prefer the shape to be circular in section
principally on account of the greater facility of manufacture. The cone may also be
pushed inward otherwise than by means of a screw, such as for instance by means of a
spring or other suitable mechanism.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The method of connecting electric wires and poles by means of an apparatus
consisting essentially of a hollow main body into which a cone or wedge
can be forced
in such a manner that any wires inserted between the cone and the internal walls of
the main body become jammed substantially in the manner as described and shewn in
the drawings.
