Improvements in Insulators for Electric Wires.
I. HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex; do hereby declare the nature
of this invention to be as follows:-
=
This invention relates to a new form of insulator for electric wires and the like.
By the employment of the improved insulator the work of laying the wires is
more quickly and more efficiently done and the insulation is more complete. The
invention is especially applicable to all kinds of house fitting, the walls and ceilings
being effectively preserved from damage and the whole work when finished having
good and even ornamental appearance.
The invention consists of a ring of porcelain, glass, hard rubber, or the like,
through the centre of which ring the wire is passed, that is to say, any required
number of rings can be threaded on to the wire before beginning to fix, the outer
circumference of this insulating ring is provided with a groove which fits into a
snap or spring hook. It will thus be seen that these spring hooks can be fastened
to the place where the wire is intended to be hung, and the said wire with its
insulators inserted at pleasure, secured thereto, the spring hooks holding the
insulators firmly in position.
The spring hooks are preferably provided with an ornamental base in such a
manner that they project from or are fixed upon an ornamental button or boss or
the like, which in its turn can be constructed as a screw hook, button, nail or the
like..

Improvements in Insulators for Electric Wires.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-

place where the wire is intended to be hung and the said wire with its insulators
afterwards inserted therein at pleasure, the spring hooks holding the insulators
firmly in position.
::
The spring hooks are preferably provided with an ornamental base in such a
manner that they project from or are fixed upon an ornamental button or boss or
the like, which in its turn can be constructed as a screw hook button, nail or the
like.
:
The invention is represented in the accompanying drawing which shows several
modifications in the construction of the improved insulators.
Figure 1 is a section of spring hook provided with an insulator.
Figure 2 a side elevation of the same.
Figures 3 and 4 represent the improved spring hook provided with insulator and
ornamental base having suitable attachments for fastening.
Figure 5 represents a modification in which the insulator is divided into
segments.
Figure 6 is a modification of the hook showing the insulator ring attached to a
tube by means of the said hook.
Figure 6 shows a further modification of the spring hook adapted for mounting
electric wires on existing gas fittings and
Figures 7, 8 and 9 represent further modifications in form of the improved
insulators.
As shown in Figures 1 and 2 the hook a is provided with an eye a¹ by which it
is secured to the wall or other support by means of a screw or nail b. The
insulator ring c is provided with a groove c by which it is elastically held in the
hook a.
Figures 3 and 4 show the hook supported upon the head d of an ornamental
nail d by being passed through a hole in the said head and bent over as shown.
In some cases the head is provided at the rear side with a bridge pièce d' or an
eye instead of the nail proper for suspension as shown in Figure 4.
In some cases the insulator ring is made in two parts as shown in Figure 5.
Figure 6 shows a modification in which the hook is made S-shaped or double, one
end a embracing the insulator ring c and the other end a being sprung onto a pipe
or tube e. Figure 64 is a further modification of the hook a adapted to carry two
insulating rings ¢ the said hook being carried by a pipe or tube e between the said
insulator rings.
Figures 7 and 8 show the hook a adapted to receive insulating pieces c of angular
form and Figure 9 shows the insulator divided in two and adapted to carry two
wires one above the other.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
First. An insulator consisting of one or more parts with a central hole for the
conducting material, and provided on the outside with one or more channels for the
reception of the support for the insulator, in combination with a support consisting
substantially of one or more spring hooks attached by one of their ends placed in
the channel or channels of the insulator and elastically embracing the same through
an arc of more than a semicircle, so that the width of the opening of the hook is
smaller than its largest interior diameter, substantially as described.
Second. The combination of the spring hook with a so-called ornamental nail,
substantially as described with reference to Figure 3 of the accompanying
drawings.
Third. The combination of a spring hook with an ornamental nail head which is
provided at the rear side with a bridge-piece or an eye adapted for the suspension
in lieu of the nail proper substantially as described with reference to Figure 4 of
the drawings, for the purposes specified.

page_text: Fourth. A spring hook constructed with a screw, substantially as described with
reference to Figure 5 of the drawings, for the purpose specified.
Fifth A spring hook having an S-shaped form constructed substantially as
described with reference to Figure 6 of the drawings, for the purposes specified.
Sixth. A spring hook subtending an angle of more than 180 degrees at the centre
and therefore having a smaller opening than its largest diameter and serving to
attach the insulator substantially as, and for the purposes specified.
Dated this 3rd day of November 1893.
