PROVISIONAL SPECIFICATION.
Improvements in Insulators for Electric Telegraph Wires and other
Electric Conductors.
I, BESSIE ADELA JEANNETTE ESPEUT, Widow and Executrix of the late
William Bancroft Espeut, of 17 Fopstone Road, Earls Court in the County of
Middlesex, Gentleman, who died on the 23rd day of October 1892, do hereby
declare the nature of this invention to be as follows:-
'My improved insulator is made of earthenware or such like material; it is of
bell like form and is fixed upon the upper end of a vertical iron stem or support;
in all which respects it resembles insulators at present in use. There is a flat
horizontal surface of circular form at the top of my insulator and a groove passes
across this surface diametrically from side to side. The telegraph wire or other
conductor lies in this groove and it is tightly held down therein by a wedge. To
receive the wedge two staples are fixed into the top of the insulator, one on either
side of the groove above mentioned. The staples are of wire doubled upon itself
and the ends of the wire are inserted into holes provided in the top of the insulator.
There are two such holes, one for each staple and the wire crosses the top of the
insulator between the holes. The staple in each case is made fast in its hole by
running molten lead into the hole around it; or a suitable cement may be used.
The wedge is of iron, it is passed through the eyes of the two staples and lightly
driven by a hammer until it bears firmly and locks the wire fast.

performed, to be particularly described and ascertained in and by the following
statement:
My improved insulator is made of earthenware or other suitable material; it is of
bell-like form and is fixed upon the upper end of a vertical iron stem or support, in all
of which respects it resembles insulators at present in use. There is a flat horizontal
surface of circular form at the top of my insulator, and a groove passes across this
surface diametrically from side to side. The telegraph wire or other conductor lies
in this groove and it is tightly held down therein by a wedge. To receive the
wedge two staples are fixed into the top of the insulator one on either side of the
groove above mentioned.
The annexed drawing illustrates my invention.
Figures 1 and 2 are elevations: in Figure 1 the wire or conductor is seen in side
view and in Figure 2 in section.
Figure 3 is a side view of one of the staples: it is preferably made of galvanized
iron wire.
Figure 4 and Figure 5 shew respectively a side view and an end view of
the wadon

page_text: In Figures 1 and 2 a is the insulator, which may be of any suitable form; bis
the iron stem on to which the insulator is fixed by means of cement or screw threads
in the usual way; c, care the two staples. The staples may preferably be of metal
wire of suitable thickness with the ends crossed back upon each other; they are
inserted into holes in the insulator and may be run in with lead or fixed with
cement such as is used in fixing the insulator on to the stem or otherwise securely
attached; d is the electric conductor lying in the groove provided for it in the
crown of the insulator; e is the key or wedge. The wedge is preferably of
galvanised iron; it is passed through the eyes of the two staples over the conductor
and is driven by a hammer with moderate force until it bears firmly and locks the
conductor fast in its groove.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1
The combination of parts substantially as described consisting of an insulator,
two metal staples made fast in the crown thereof on each side of the conductor and
a key or wedge passing through the staples and locking the conductor fast between
them and the surface of the insulator.
