PROVISIONAL SPECIFICATION.
An Improved Device or Tool for Twisting Together the Ends
of Wires.
1, ERNEST GUSTAV HOFFMANN of 5 Clarendon Villas, Beaconsfield Road,
New Southgate in the County of Middlesex, Engineer, do hereby declare the nature
of this invention to be as follows :-
My invention relates to an improved device or tool for twisting together the ends
of wires desired to be secured to each other, such for instance as telegraph,
telephone, bell, electric light, and other wires. I have also found it to be the best
means known to me for securing together the ends of the wires employed for
fastening rubber tyres to wheels, which invention is the subject of an application
for Letters Patent made by me on the 22nd May 1890, under No. 7901.
It is well known that in twisting two wires together by wire nippers or pincers
one wire will usually wrap round the other and by reason of the short turns and
strain on the metal frequently breaks in so doing. To obviate this to a large
extent and to cause the wires to twist evenly 1 propose to use a tool or device
which consists of a handle having a boss on the shank, said boss having two or
more holes through one of which each wire is threaded and temporarily secured by
The
twisting around the handle or passing through corresponding holes in same.
tool has a central hole through which I pass a piece of hard steel wire or rod,
allowing it to project a short distance from the boss, or the boss may be furnished
with a central pin, though I prefer the loose rod. When the tool is turned to
tighten up the wires they will be twisted around this rod or pin in regular convolu-
tions instead of upon one another, and will thus produce an even twist. When
sufficiently twisted if a loose rod is employed it is withdrawn and a further slight
turn may then be given to the tool to close up the twist or spiral formed. The
ends of the wires are then nipped off and the tool is withdrawn. The tool may be
adapted for twisting more than two wires together if required.

COMPLETE SPECIFICATION.
An Improved Device or Tool for Twisting Together the Ends
of Wires.
I, ERNEST GUSTAV HOFFMANN of 5 Clarendon Villas, Beaconsfield Road,
New Southgate, in the County of Middlesex, 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 :-
My invention relates to an improved device or tool for twisting together the ends
of wires desired to be secured to each other, such for instance as telegraph,
telephone, bell, electric light and other wires. I have also found it to be the
best means known to me for securing together the ends of the wires employed
for fastening rubber tyres to wheels, which invention is the subject of an
application for Letters Patent made by me on the 22nd day of May 1890,
under No. 7901.
It is well known that in twisting two wires together by wire nippers or pincers
one wire will usually wrap round the other instead of the two twisting equally, and

page_text: by reason of the short turns and strain on the metal so produced frequently break
in so doing.
To obviate this 1 employ the tool represented in the necompanying drawings
in which :-
Fig. 1 is a view of same in section shewing the wires about to be twisted,
and
Fig. 2 is a view in elevation showing two wires twisted together.
Fig. 3 is a plan while
Fig. 4 shows a portion of a wheel rim in section with a rubber tyre secured
thereto by the means previously referred to.
The device or tool consists of a shank having handles g at one end, and a boss h
at the other. This boss has two holes therein as shown, through which the two
ends of the wire d are passed, while to temporarily secure then they are passed.
through two holes in the handles and tightly twisted together beyond same as
shown in Fig. 3. The shank has a central hole through which a hard steel rod i
is passed, the point of which may be slightly tapered, its end being allowed to
project a short distance through the boss. When the tool is twisted the ends of
the wire d will be twisted regularly around the rod in even spirals or turns, and
the wires at the same time will be drawn tight. When the wires are drawn up
sufficiently tight the rod is gradually withdrawn so as to clear one or two of the
spirals, and a partial turn is given to the tool to close up or lock tight the Inst
spirals or coil at the point. Fig. 2. The rod is then completely withdrawn and
the remaining coils closed up by a turn or two of the tool, after which the ends of
the wire may be nipped off and the tool removed.
Instead of the loose rod a fixed pin projecting from the boss may be employed
but it is not so desirable, while if the tool has more holes formed in the boss it
may be employed for the twisting together of a number of wires which require
drawing up when securing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The improved device or tool for twisting together the ends of wires, having
holes for receiving the respective wires, a central rod or pin around which the wires
are twisted, and a suitable handle, substantially as described.
2. The improved device or tool for twisting together the ends of wires, having
holes for receiving the respective wires, a central loose rod having a tapered end
around which the wires are twisted, means for securing the wire ends and a suitable
handle, substantially as described.
