PROVISIONAL SPECIFICATION.
An Improvement in Brackets for Telegraph Poles.
We, SIEMENS BROS. & Co. LIMITED, of 12 Queen Anne's Gate,
Westminster, in the County of Middlesex, and GEORGE WILLIAM PERRY of
119 Algernon Road, Lewisham, in the County of Kent, Electrical Engineers, do
hereby declare the nature of this invention to be as follows:-
:-
In exposed situations, the insulators on iron telegraph poles are liable to be
broken, and in such cases the line wire falling on the iron bracket is connected to
earth through the metal pole. The object of the present invention is to provide a
second insulation between the line wire and the iron pole. For this purpose, we fix
studs of non conducting material, such as glass or earthenware, in recesses formed
inside the iron bracket which carries the insulator and the saddle by which the
bracket is secured to the pole. Thus, when the bracket is fixed, these insulating
studs bear on the iron pole insulating the bracket from the pole, so that, should
the line wire fall on to the bracket, it is not thereby put into metallic connection
with earth.
Dated this 5th day of December 1894.

An Improvement in Brackets for Telegraph Poles.
12 Queen Anne's Gate,
We, SIEMENS BROS. & Co. LIMITED, of
Westminster, in the County of Middlesex, and GEORGE WILLIAM PERRY, of
119 Algernon Road, Lewisham in the County of Kent, Electrical Engineers, 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:-
In exposed situations, the insulators on iron telegraph poles are liable to be
broken; and in such cases the liue wire falling on the iron bracket is connected to
earth through the metal pole.
The object of the present invention is to provide a second insulation between
the line wire and the iron pole. For this purpose we construct and fix the brackets
as we shall describe referring to the accompanying drawings. Fig. 1 is a plan and
Figs. 2 and 3 are respectively longitudinal and transverse sections of a bracket
according to our present invention, which we form with recesses in which we fix
studs A of non-conducting material, such as glass or earthenware.
We fix similar studs B also in recesses formed inside the saddle S by which the
bracket is secured to the pole. Thus, when the bracket is fixed by screwing up
the nuts on the bolts C the insulating studs A and B bear on the pole P insulating
the brackets from the pole, so that, should the line wire fall on to the bracket,
it is not thereby electrically connected with earth, even when the pole is of
metal

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A bracket and saddle for telegraph poles made with internal recesses containing
insulating studs which bear against the pole, substantially as for the purpose set
forth.
