PROVISIONAL SPECIFICATION
Improvements in the Method of and Means employed for connecting
the Guard Wires of Electric Cables, and for Disconnecting same in
Case of Breakage.
We, RALPH BOSTOCK, of White Swan Inn, Brighouse, in the County of York,
Licensed Victualler, and FRANK ARTHUR CHEETHAM, of Longroyd, Brighouse
aforesaid, Silk Spinner, do hereby declare the nature of this invention to be as
follows
-
This invention relates to improvements in the method of and means employed
for connecting the guaid wires of overhead electric cables as used for tiams and
electric railways the object being to divide the guard wires into sections or bays
in such a manner that should one of the wes be broken at any point between
two of the supporting poles or brackets, the wie will be instantaneously liberated
and dropped at each pole or bracket, ze at the next points on each side of the
breakage and where the improved appliances are used.
The improved appliance for connecting the guard wies as aforesaid consist of
a block or slide, one of such being attached to each of the supporting poles or
brackets Inside the end of each slide or block is pivoted a semi-circular disc or
a hook, to which are attached the ends of the adjacent guard wires Each hook
or disc is by link connected to a bell-crank lever pivoted in the block or slide and
its outer end provided with a counterbalance weight
The tension on the guard we maintains the hook and counterbalance weight in
an outward position, but in the event of the wire breaking, the counterbalance
weight acting on the link and hook or disc, raises the latter and liberates the end
of the wire which 18 looped thereon
In order to ensure the wire being liberated a metal plate is preferably attached
to the wire between the latter and the block, and as the hook or diso is raised, the
plate pushes off the loop or end of the wire from the hook

FRANK ARTHUR CHEETHAM, of Longroyd, Brighouse, aforesaid, Silk Spinner, 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 relates to improvements in apparatus for holding and connecting
guard wires of electric cables and other wies electric or otherwise, the object
being in the case of guard wues of overhead electric cables as used for tramways
and railways to divide such wires into sections in such a manner that should one
of the wires be broken at any point between two of the supporting poles or brackets,
that we will be at once liberated and dropped at each pole or bracket, that is at
the next points or each side of the breakage.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which:
-
Fig 1 is a sectional side elevation shewing a wire attached on one side and
released on the other side.
Fig 21s a plan view of Fig 1 looking upward
According to this invention the apparatus consists of a block a having a hook or
ing b or other means for attaching same to the usual supporting pole or bracket.
The block is slotted or open at c and at d, d respectively and on either side of the
opening c at one end it carries two bearings ee (of which only one is shown) there
being similar bearings el, el on the other end Between these bearings are held
pins f, f on which are pivoted cranked levers g, g' (the short ends of which can
partly enter the alot c) carrying adjustable weights, while the short ends have
pivotally connected to them links h, h pivotally connected in turn to hooks 2, 2¹
hung on pins 3, in the slots d, d' respectively
The hooks s, 21
carry the wires k, preferably through the medium of a slotted
plate as such plate having an adjusting or tightening screw carrying a ring
or hook to which the wire is attached, or in place of this plate a slotted plate
or a ring such as I may be used for engaging with the hooks, the object of using a
stiff plate or the like being to ensure the wire being liberated a loop of wire
engaging with the hooks being liable to jam.
In use a wire such as is stretched between the hook and the corresponding
hook on a similar apparatus at the next pole or bracket, and the tension on the
wire on hook 2¹ serves to keep the weighted lover g¹ in its raised position as
shewn.
b
As soon as a breakage of such wire k occurs the weighted lever falls and the
hook being drawn into the slot d' disengages itself from the plate of the wire
and thus drops that end of same, a similar operation taking place with the apparatus
holding the other end so that both ends are released and that section falls away
from the posts or brackets. The parts then assume the position shewn on the
left hand side of Figs. 1 and 2, but it will be understood that the falling of one
section makes no interference with the next section which is held at one end by
the other hook of the apparatus.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
-
(1) The general construction, arrangement, and combination of parts constituting
the improved apparatus for connecting guard wires of electric cables as and
for the purpose herein described and substantially as illustrated by Fig. 1 of the
annexed drawings
(2) The weighted lever g, link h, and hook z carried in a block such as a and
the wire k all in combination as and for the purpose herein described and sub-
stantially as illustrated by Fig. 1 of the accompanying drawings.

page_text: (3) The weighted lever g, link h, hook i, slotted plate , and adjusting or
tightening screw, all in combination as and for the purpose herein described and
substantially as illustrated by Figs 1 and 2 of the annexed drawings
