I, ALFRED ELLIS HARRIS, of 66, Finsbury Pavenient, in the County of Middlesex,
Dentist, do hereby declare the nature of this invention to be as follows:-
This invention relates to suspending telegraph, telephone and like wires in such a
manner that they shall not be liable to be broken from the effects of the weather, and
the invention consists in so joining or connecting the wires to their posts or supports
so that in the event of the wires contracting from the effects of cold or by their being
subjected to a weight of snow, or being acted upon by a high wind, the connections
will by being formed of a spring, or a socket and set screw, or of jointed levers, or in
any other suitable manner, expand or be elongated so as to release the wires from the
strain to which they are subjected.

Improvements in Suspending Overhead Telegraph, Telephone,
and like Wires.
1 ALFRED ELLIS HARRIS, of 66, Finsbury Pavement, in the county of Middlesex,
Dentist 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:
This invention relates to suspending telegraph, telephone and like wires in such a
manner that they shall not be liable to be broken from the effects of the weather and
the invention consists in so joining or connecting the wires to their posts or supports
that in the event of the wires contracting from the effects of cold or of their being
subjected to a weight of snow, or being acted upon by a high wind, the connections
will by being formed of a spring, or a socket and set screw, or of jointed levers, or in
any other suitable manner, expand or be elongated so as to release the wires from
the strain to which they are subjected.
In order to enable my invention to be fully understood I will proceed to describe
by reference to the accompanying drawing several suitable arrangements for carrying
the same into practice.
In figures 1 and 2, a, is a telegraph post or pole which I provide with rods b, b; on
these rods slide vertical bars or arins c, c, to which bars or arms are connected the
telegraph wires d, d; e, e, are the springs on the bars b, b, which normally keep the
bars or arms c, c, in the position shewn in figure 1 of the drawing but should
the wires d, d, contract or be subjected to any undue strain from any cause whatever
the springs e, e, will be compressed and the bars c, c, moving outwards from the
post a, will relieve the strain or pressure on the wires d, d, and thereby prevent them
breaking. The wires d, d, between the insulators are joined up by wire loops or in
any other suitable manner.
In figure 3 the arms c, c, are shewn jointed to the upper part of the post at f, f, the
springs e, e, keeping the lower ends of the bars c, c, in their normal position. The
action of this arrangement will be understood without further description.
In figure 4 the arrangement shewn is substantially the same as that shewn in
figure 3 except that the bars c, c, are extended above the joints f, f, and their upper
ends are connected by a spring e.
In figure 5 I provide the post a, itself with a spring e, which will allow the post to
bend at the spring if the wires are strained to an abnormal extent. Figures 6 and 7
shew an elevation and a section shewing the wire d, connected to the post a, or wall
or the like by a spring link arrangement.
Figure 8 shews the wire d, corrugated just before it is connected to the post a, or
wall or the like or the corrugations may be formed separately and connected to the
wire. In this arrangement the corrugated portion acts as a spring and may be used
alone or in conjunction with any of the above described arrangements.

page_text: All the arrangements hereinbefore described and illustrated have the same object in
view, namely, to allow of the wires d, being elongated when subjected to undue strain
or pressure so as to prevent their liability to break as when suspended by the ordinary
means hitherto in use.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. Suspending telegraph, telephone and like wires by means of supports constructed
so as to give to some extent upon the application of abnormal strain to the wire so as
to relieve the strain substantially as hereinbefore described.
2. An elastic support for telegraph, telephone or like wires constructed so that, upon
the application of an, abnormal strain upon the wire, the strain may be relieved by
the expansion or giving of the supports substantially as herein before described.
3. A support for telegraph, telephone or like wires consisting of an insulator or
series of insulators mounted upon a bar or lever or slide in combination with a
spring or springs controlling the movement of the bar or lever substantially as
hereinbefore described.
4. The several kinds of clastic support for telegraph, telephone and like wires
hereinbefore described and respectively illustrated in figures 1 and 2, figure 3, figure 4,
figure 5, figures 6 and 7 and figure 8 of the accompanying drawing.
