PROVISIONAL SPECIFICATION.
Improvements in Brackets for Poles or Standards for Electrical
Conductors and similar purposes.
We, SIEMENS BROS. & Co. LIMITED, of 12 Queen Anne's Gate, Westminster,
in the County of London, 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:-
This invention has for its object the construction of a bracket with the means for
fastening it to the pole or standard, consisting of as few pieces as possible and
requiring the simplest form of tools for fixing it, in order to avoid the liability to
delay in erection in more or less remote localities owing to one or more of the parts
or the tools becoming lost.
Such brackets, as heretofore constructed, are usually composed of six parts,
namely the bracket proper, a saddle piece, and two screw bolts with their nuts, for
securing the bracket to the saddle piece.
The
According to the present invention we construct such brackets of two parts only,
so arranged as to be secured together and to the pole by a wedging action.
said parts consist firstly of the bracket proper, the portion of which that partly
embraces the post or standard has two wings in which are formed inclined slots, and
secondly, a saddle piece or bar the ends of which take into the said inclined slots, so
that when placed in position, the bracket is effectually secured to the post by
driving the saddle piece up or down in the inclined slots, whereby it is made to grip
the pole firmly between it and the bracket.
The saddle piece may either be removeable from the bracket, or it may be
pern:anently retained in engagement therewith by providing the ends thereof that
project through the slots with external heads or other devices that prevent it from
passing out of the slots.
According to another modification, the inclined slots are formed in the saddle
piece, and the bracket is formed with projecting lugs engaging with the said slots.
According to another modification, instead of the slot being made with a
continuous incline it may be provided with a number of step-like projections, each
one of which projects farther than the one next above it." This arrangement is
applicable more particularly for posts or supports of which the part on which the
bracket is fixed is formed conical or tapering.
When it is desired to insulate the bracket and saddle piece from the pole
or standard, studs of suitable insulating material may be fixed in or on the inner
surfaces of the parts so as to keep these out of conducting contact with the pole.
According to another modification, instead of producing the wedging action by
means of inclined slots as described, the two parts may be made to engage with
each other by means of hooked ends having inclined or wedge shaped meeting
surfaces.

Conductors and similar purposes.
We, SIEMENS BROTHERS & Co. LIMITED, of 12 Queen Anne's Gate,
Westminster, in the County of London, 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 :-
This invention has for its object the construction of a bracket with the means for
fastening it to the pole or standard, consisting of as few pieces as possible and
requiring the simplest form of tools for fixing it, in order to avoid the liability to
delay in erection in more or less remote localities owing to one or more of the
parts or the tools becoming lost.
Such brackets, as heretofore constructed, are usually composed of six parts,
namely, the bracket proper, a saddle piece, and two screw bolts with their nuts, for
securing the bracket to the saddle piece.
According to the present invention we construct such brackets of two parts only,
so arranged as to be secured together and to the pole by a wedging action as we
shall describe referring to the accompanying drawings.
Fig. 1 is a side view and Fig. 2 is a plan shewing one fixing arrangement
according to our invention.
First, the bracket proper B which partly embraces the post or standard A has
two wings b in which are formed inclined slots C and secondly, a saddle piece or
bar D has ends d d bent to engage in the inclined slots C so that the bracket is
effectually secured to the post by driving the saddle piece up, its ends with the
incline of the slots acting as wedges, causing the pole A to be firmly gripped
between the saddle D and the bracket B.
The saddle piece may either be removeable from the bracket, or it may be
permanently secured in position by fixing pins such as E in the ends that project
through the slots or by bending the ends back as shewn at F or by other devices
that prevent the ends from passing out of the slots.
According to a modification shewn in side view in Fig. 3 and in plan in
Fig. 4 the inclined slots C are formed in the saddle piece D and the bracket B
is made with projecting lugs engaging with these slots.
Instead of making the slot with a continuous incline it may be made narrowing
by steps as shewn in side view in Fig. 5 thus adapting the fixing more particularly
to posts or supports which taper where the brackets are fixed.
When it is desired to insulate the -bracket and saddle piece from the pole or
standard, studs of suitable insulating material may be fixed in or on the inner
surfaces of the parts so as to keep these out of conducting contact with the pole, as
described in the Specification No. 23685 of 1894.
Instead of producing the wedging action by means of inclined slots as above
described, the bracket and saddle may be made to engage with each other as shewn
in side view in Fig. 6 and in plan in Fig. 7 by means of hooked flanges G the one
having inclined or wedge shaped surfaces engaging similar inclined hooked flanges H
of the other.
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 :-
1. The herein described method of fixing a bracket on a pole or standard by

page_text: wedging projecting limbs or flanges of the saddle into inclined slots or along inclined
flanges of the bracket or conversely.
2. A bracket and saddle constructed and secured substantially as described with
reference to Figs. 1, 2, or 3 and 4.
3. A bracket and saddle constructed and secured, substantially as described with
reference to Figs. 6 and 7.
4. A bracket and saddle constructed and secured substantially as described with
reference to Fig. 5.
