I WILLIAM BAINBRIDGE, of the City of Omaha, County of Douglas, State of
Nebraska, United States of America, Inventor, do hereby declare the nature of this
invention to be as follows:-
My invention relates to a device for coupling the ends of wires, and my object
is to produce a more simple, cheap and effective arrangement than those hitherto in
use.
With these ends in view, my invention consists in the peculiar features and com-
bination of parts more fully described hereinafter.

its length whereby one end of the chamber is made larger than the opposite end. The
inferior chamber of the sleeve is by preference given a rectangular form in horizontal
cross section. The top of the sleeve through line xx, of Fig. 1, is oblong while the
lower opening is inore nearly square.

The opposite walls of the wedge are provided with serrations or corrugations z,
corresponding approximately with the inner walls of the sleeve, in order to secure as
much frictional bearing surface as possible throughout the length of both parts. This

slipping loose.

In using my invention, the operator simply places the opposite ends
wires f, into the sleeve. The wedge is then inserted between the wires and driven
home as shewn in Fig. 1. The wires f, being bent around. the lower corners of the
sleeve form an acute angle and render slipping much more difficult.

When this occurs, a sleeve with straight inclined walls in combination with a wedge
provided with corresponding surfaces may sometimes be employed as shewn in Figs. 5
and 6.
In this case a recess R, to receive the larger wires is made in one side of the
wedge.
In figs. 7 and 8, a sleeve which is oval in horizontal cross section and provided with
a slot o, on one side may be resorted to. In using this modification the ends of the
wires are made to overlap each other and the wedge is driven in at the side.
The modification shown in Fig. 9, shews the ends of the wires overlapping each
other with a trough shaped sleeve having a longitudinal slot o, for the reception of the
wires and the wedge is driven alongside the wires in such a manner as to cover said
slot o, and lock the wires together.
It is evident that many other slight changes which might suggest themselves to a
skilled mechanic could be resorted to without departing from the spirit and scope of my
invention, hence I do not limit myself to the precise construction herein described and
shewn in the drawings.

page_text: I, WILLIAM BAINBRIDGE, of the City of Omaha, County of Douglas, State of
Nebraska, United States of America, Inventor, 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 :-
My invention relates to a device for coupling the ends of wires, and my object
is to produce a more simple, cheap and effective arrangement than those hitherto
in use.
With these ends in view, my invention consists in the peculiar features and
combination of parts more fully described hereinafter and pointed out in the claims.
In the drawings filed with my provisional specification Fig. 1, represents a sectional
elevation of my invention; Fig. 2, .a top view.; and Figs. 3, 4, 5, 6, 7, 8 and 9,
modifications.
The reference letter a, denotes a sleeve having straight converging walls throughout
its length whereby one end of the chamber is made larger than the opposite end. The
interior chamber of the sleeve is by preference given a rectangular form in horizontal
cross-section. The top of the sleeve through line xx, of Fig. 1, is oblong, while the
lower opening is more nearly square.
b, indicates a wedge having corresponding surfaces of a length and width sufficient
to enter the interior of the sleeve, yet leave enough room for the reception of the
ends e and d, of wires f.
The opposite walls of the wedge are provided with serrations or corrugations z,
corresponding approximately with the inner walls of the sleeve, in order to secure as
much frictional bearing surface as possible throughout the length of both parts. This
construction ensures a more tenacious hold of the wires and prevents them from
slipping loose.
In using my invention, the operator simply places the opposite ends c, d, of the
wires, into the sleeve. The wedge is then inserted between the wires and driven
home as shown in Fig. 1. The wires f, being bent around the lower corners of the
sleeve form an acute angle and render slipping much more difficult.
It sometimes becomes necessary to connect wires of different diameters. When
this occurs,
a sleeve with straight inclined walls in combination with a wedge
provided with corresponding surfaces may sometimes be employed as shown in
Figs. 5 and 6.
In this case a recess R, to receive the larger wires is made in one
side of the wedge.
In Figs. 7 and 8, a sleeve which is oval in horizontal cross-section-and provided
with a slot o, on one side may be resorted to. In using this modification the ends
of the wires are made to overlap each other and the wedge is driven in at the
side.
The modification shown in Fig. 9, shows the ends of the wires overlapping each
other within a trough-shaped sleeve having a longitudinal slot o, for the reception of
the wires and the wedge is driven alongside the wires in such a manner as to cover
said slot and lock the wires together.

page_text: It is evident that many other slight changes which might suggest themselves to a
skilled mechanic could be resorted to without departing from the spirit and scope of
my invention, hence I do not limit myself to the precise construction herein described
and shown in the drawings.
Having thus described the preferred form and leading characteristics of my inven-
tion, what I claim as new and desire to secure by letters-patent is :
Claim 1. The combination in a wire coupling of a sleeve provided with a central
chamber larger at one end than at its opposite end, and having internal walls inclined
toward each other, a removable wedge having serrated or corrugated exterior surfaces
corresponding approximately to said walls of the sleeve, and wires interposed between.
the wedge and sleeve, in the manner and for the purpose set forth.
Claim 2. The combination in a wire coupling, of a sleeve provided with a central
chamber larger at one end than at its opposite end, and having straight inner walls
inclined toward each other throughout the length of the sleeve, a wedge having
corresponding surfaces an inclined exterior surface corresponding with the inner
walls of the sleeve, and wires interposed between the wedge and sleeve, in the manner
and for the purpose described.
