HOWARD COCHRANE JOBSON of Dudley in the County of Worcester IMPROVE
MENTS IN SUSPENDING TELEGRAPH WIRES FROM IRON POSTS
"
This Invention has for its object improvements in suspending telegraph wires
from iron posts.
In places, where iron posts are much used, it is usual to provide the post with iron
brackets and these brackets support the insulators. Now the insulators are liable
to be broken by lightning and otherwise and then the electrical leakage from the
wires becomes very large. To obviate this I provide the post with wooden arms
which I secure upon the posts in the following manner :-The arm consists of a bar.
of wood about two feet long and it has holes or sockets to receive the stems of
insulators. Two bolts are passed through the arm and also through an iron plate,
which has a lip or flange upon its under side for the wooden arm to lie upon.
The plate has also ribs or projections upon it and when the arm is applied these
projections take a steady bearing against the post so that the parts, when the nuts
are screwed up, may not "work or shift in position. The bolts also pass through a
back piece applied upon the further side of the post. When the nuts are screwed
up against washers upon the outer side of the arm, the whole of the parts are
drawn tightly together, the post is nipped and the wooden arm becomes securely
held to the post.

This Invention has for its object improvements in suspending telegraph wires
from iron nosts.

consists of a bar of wood about two feet long and it has holes or sockets to receive
the stems of insulators Two bolts are passed through the arm and also through
an iron plate which has a lip or flange upon its underside for the wooden arm to
lie upon.
The arm
The plate has also ribs or projections upon it and when the arm is applied, these
projections take a steady bearing against the post, so that, the parts when the nuts
are screwed up may not move or alter their position. The bolts also pass through
a back piece applied upon the further side of the post. When the nuts are screwed
up against washers upon the outer side of the arm, the whole of the parts are
drawn tightly together, the post is nipped and the wooden arm becomes securely
held to the post.
In order that my invention may be fully understood I have shewn in the drawings
hereunto annexed separate views of each of the parts above mentioned.
Figure 1 is a back view and Figure 2 a top edge view of the back piece A of the
clip Figure 3 is a plan view Figure 4 a back view and Figure 5 an end view of
the front piece B of the clip. Figure 6 is a plan view and Figure 7 an end view of
the wooden arm C. Figure 8 shews one of the bolts D by which the parts of the
clip are to be drawn together and made to nip the post. Figure 9 is a plan view
of the several parts when put together the post is shewn in section-the manner in
which the parts A. B and D secure the wooden arm C to the post is clearly shewn
by this figure. C¹are holes in the wooden arm C to receive the steins of insu-
lators two such holes only are shewn but they might be made to carry a greater
number of insulators if required. B'are the projections at the back of the piece B
which are to bear against the post-they are at the upper and lower edge of the
piece B so that when they all are drawn firmly against the post the clip cannot
move or alter its position.
In the Drawings the piece B is shewn to be formed with a flange B2, along its
lower edge for the wooden arm to lie upon-it might however be formed without
this flange.
Having thus described the nature of my Invention and the manner of performing
the same I would have it understood that I claim :-
First. Securing to iron telegraph posts wooden arms carrying insulators for
suspending telegraph wires substantially in the manner herein before described.
Second. The clip piece B, with its projections B¹ for securing wooden arms to
iron telegraph posts substantially as described.
In witness whereof I the said Howard Cochrane Jobson have hereunto set my
hand and seal this ninth day of February in the year of our Lord One
thousand eight hundred and eighty three.
