PROVISIONAL SPECIFICATION.
An Improvement in Insulators and Appliances for Fixing, Tightening,
and Retaining Telegraph Wires, Electric Wires, and other Wires
or Ropes.
.HERBERT HOBSON No. 15 High Street Heywood in the County of Lancashire,
Mechanic, SHEPHERD RUSHTON No. 13 Collinge Street Heywood in the County of
Lancashire Wire worker, and ALFRED WOOD No. 111 Long Street Middleton near
Manchester in the County of Lancashire, Engineer, do hereby declare the nature of
this invention to be as follows :-
An Improvement in Insulators and appliances for fixing, tightening and retaining
Telegraph Wires, Electric Wires and other Wires or Ropes.
Our Invention relates to Insulators made of clay, glass, or other materiel such as
are used and may be suitable for buildings internally, externally, the open air, or
underground passages, for supporting Telegraph Wires, Electric Wires, and other
Wires, Conductors or Ropes and tightening and retaining the same in any fixed position.
It also relates to holding tightening and retaining Wires and Ropes such as are
used for land purposes, mechanical, marine, and other purposes such being of varied
strengths and in various positions.
Our Insulator is a plain round one oblong, or other shape, or grooved vertically, or
spirally with a slot or groove across the centre, at one end, of sufficient depth for
reception of a Wire or Rope, or other materiel, so that they may be wound on the
Insulator equally from both ways. A curved recess is also made in the centre of top
end for reception of a small boss that forms part of a loose hood or cover for the
Insulator as a preventative against an excess of moisture on the Insulator and
Wire.
The Insulator is placed or fixed on a rod or stud the upper end of which is made
as a two pronged fork and which fits the Insulator internally thus securing them
together internally and rigidly, and giving additional strength by sustaining the two
upper ends of the Insulator on each side of the groove.
The middle portion of the stud is square the lower part is round so as to enable
the stud to turn freely when it is placed in position in a socket of iron or other suit-
able materiel.
It is prevented from lifting by means of metal pin or cotter or nut attachid at
the lower end.
This pronged stud being placed in the aforenamed socket on one end of which is
a ratchet or toothed disc wheel and on the underside of which are two brackets which
keep the socket in position and also prevent it turning when fixed in the wood cross
bar of the Telegraph Post or other fixing as may be requisite for the position.
Another similar toothed disc wheel having a hoop or outer rim, but no socket it is
made with a square hole so as to fit loosely on the middle or square part of the stud.
When in position these disc wheels work together the upper one being loose slides
up the stud when it is turned by a key causing the teeth to slide over one another
thus tightening and also retaining both ends or sections of the Wire or Rope
simultanously by winding round the Insulator, to ensure the falling of the upper
disc wheel when being turned. A spiral or other spring may be placed between it and
the forked end of the stud.
In order that our Invention may be better understood we have hereunto attached
a Sheet of Drawings.

Having now fully set forth and indicated the nature of our said Invention and
the manner in which the same may be carried into effect we would have it to be under-
stood that what we claim is. First. The grooved Insulator and fixings substantially as
and for the purposes described and indicated hereinbefore and by the accompanying
Drawings. Second. The method of tightening Wires, Ropes, or other substances by
rotary motion and retaining them by means of the stem or stud and joint appliancos.
And lastly we do not bind ourselves to keep to the exact style or method as per
drawings but to retain the principal.
In witness whereof we the said HERBERT HOBSON, SHEPHERD RUSHTON and
ALFRED WOOD, have herennto seat our hands and seal this First day of
February in the year of our Lord One thousand eight hundred and eighty
nine-1889.

COMPLETE SPECIFICATION.
An Improvement in Insulators and Appliances for Fixing, Tightening,
and Retaining Telegraph Wires, Electric Wires, and other Wires
or Ropes.
HERBERT HOBSON of No. 15 High Street Heywood in the County of Lancashire
Mechanic SHEPHERD RUSHTON of No. 13 Collinge Street Heywood in the County of
Lancashire Wiro Worker, and ALFRED WOOD of No. 111 Long Street Middleton in
the County of Lancashire Engineer, 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:—
An Improvement in Insulators and appliances for fixing, tightening and retain-
ing and also relaxing, Telegraph Wires, Electric Wires, and other Wires, Chains,
Conducters, Ropes, or flexable substances.
Our Invention relates to Insulators and Blocks with grooves or holes and made of
clay, glass, wood, metal, or other materiel such as may be suitable for buildings
internally, externally, the open air, or underground passages, for supporting Telegraph
wires, Electric wires, and other wires, Chains, Conducters, Ropes, or flexable
substances, and tightening and retaining them and also relaxing them to any fixed
position.
In preference we use the grooved or holed block made of suitable materiel
when used for signal and other wires &c. It also relates to holding tightening
and retaining Wires, Chains, Ropes, or flexible connections, such as are used for
land purposes mechanical, marine, and other purposes, such being of varied strengths
and in various positions.
Our Insulator and Block with grooves or holes is a round one oblong, plain or
concave surface, or other shape, or grooved vertically or spirally, with a slot or groove
across the contre at one end of sufficient depth for reception of a Wire, Chain, or
Rope, or other flexible materiel, so that they may be wound on the Insulator or
Block with grooves or holes equally from both ways. A curved recess is also made
in the centre of the top end for reception of a small boss that forms part of a loose
hood or cover for the insulator and wire and as a preventative against an excess of
moisture.

page_text: The Insulator is placed or fixed on a rod or stud the upper end of which is made as
a two pronged fork and which fits the Insulator internally thus securing them together
and giving additional strength by sustaining the two upper ends of the Insulator or
grooved block on each side of the groove. The middle portion of the stud is square
the lower part is round so as to enable the stud to turn freely when it is placed in
position in a socket of iron or other metal or suitable materiel. It is prevented from
lifting by means of a metal pin or cotter or nut attached at the lower end.
This pronged stud is placed in the aforenamed socket on one end of which is a
ratchet toothed disc wheel and on the underside of which are two brackets that keep
the socket in position when placed in the wood cross bar of the Telegraph Post or
other fixing that may be requisite for the position.
Another similar ratchet toothed disc wheel having a hoop or outer rim but no
socket. It is made with a square hole so as to fit loosely on the middle or square
part of the stud. When in position these disc wheels work together the upper one
heing loose slides up the stud when it is being turned by a key on the middle or at
the end of the stud causing the teeth to slide over one another thus tightening and
also retaining both ends of the Wire or Rope simultanously and winding round the
Insulator. Where adviseable the stud and grooved or holed block may be made in
one piece.
The Insulator or grooved or holed block may if adviseable be put under the wood
cross bar or fixing in lieu of being on the top as is now done.
In order that our Invention may be better understood we have hereunto attached a
sheet of drawings.

ratchet toothed disc wheel and loose disc wheel as fixed in the wood cross bar.

Having now fully set forth and indicated the nature of our said Invention and
the manner in which the same may be carried into effect, we would have it to be
understood that what we claim is-
First. The deep grooved Insulators and grooved or holed blocks and fixings for
the purposes herein shown and described.
Second. The ratchet toothed disc wheels and also the boss socket herein before
described.
Third. The stud or pronged fork for carrying the Insulator.
Fourth. The method of tightening and retaining and relaxing Wires, Chains, Ropes
and flexible connections by rotary motion having one or more blocks or Insulators.
In witness whereof we the said HERBERT HOBSON, SHEPHERD RUSHTON and
ALFRED WOOD have hereunto set our hands and seal this Twenty-ninth day of
October in the year of our Lord One thousand eight hundred and eighty-nine.
