PROVISIONAL SPECIFICATION.
"A New or Improved Manufacture or Construction of Wire or
Metallic Cord."
I, FRANK BROOK of Cloth Hall Street, Huddersfield, Yorkshire, Watchmaker,
do hereby declare the nature of this invention to be as follows:-
This invention refers to a new or improved manufacture or construction of wire
or metallic cord which is more particularly intended to form a substitute for
clock chains and to displace the twisted wires now employed in weight clocks, but
which can also be used tor suspending pictures or like articles and for other pur-
poses where its strength and structure are an advantage.
At present twisted wires are frequently employed in time pieces as substitutes
for chains as well as for carrying the weights in weight clocks. These twisted
wires answer the purpose for a time, but in the event of any portion thereof being
bent or receiving a slight twist, as very frequently happens, a kink or weak place
is formed which causes the wire or wires concerned to snap asunder, the broken
ends then projecting outwards from the wire in such a manner as to be liable to
get caught in the clockwork mechanism and also to interfere with adjacent coils
or wires.
The object of my invention is to manufacture or construct a wire in which
liability to fracture will be reduced to a minimum and the projection of broken
ends avoided.
In carrying out my said Invention I employ a core or centre composed of steel or
other suitable metallic wires twisted together and of sufficient strength to resist
extension. Around this twisted core I weave. plait or interlace, by suitable
mechanism, other wires composed of brass, phosphor bronze, copper or other suit-
able metal or a combination of metallic wires which are crossed under and over
each other alternately or in corresponding order in such manner as to bind each
wire down at short intervals apart throughout its entire length so that if a wire
should break there is not sufficient length exposed as to enable the severed ends
to project. The plaited or interlaced wire covering is preferably composed of a
Hexible or ductile metal which will allow of sharp curvature of the wire without
liability to kink or of any of the strands to break, the core being strong enough
o support the tension placed on the wire. In some cases, the twisted core may not
be required and in this case I weave or plait the wires together in tubular form as
in above described covering but with a hollow centre or core. The employment
of wires of different metals, or of wires plated, burnished, enamelled, lacquered or
otherwise differently coated, will give pleasing and novel effects and designs in
metallic cords for suspending pictures and the like. Fibres may be introduced
and combined with the wires, if desired.
In making hollow metallic cord, the wires are, preferably, first stretched.

I, FRANK BROOK, of Cloth Hall Street, Huddersfield, Yorkshire, Watchmaker,
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 refers to a new or improved manufacture or construction of wire
or metallic cord which is more particularly intended to form a substitute for
clock chains and to displace the twisted wires now employed in weight clocks but
which can also be used for suspending pictures or like articles and for other pur-
poses where its strength and structure are an advantage.
At present single twisted wires are frequently employed in time pieces as substi-
tutes for chains, as well as for carrying the weights in weight clocks. These twisted
wires answer the purpose for a time but, in the event of any portion thereof being
bent or receiving a slight twist, as very frequently happens, a kink or weak place
is formed which causes the wire or wires concerned to snap asunder, the broken
ends then projecting outward from the wire in such manner as to be liable to
get caught in the clock mechanism and also to interfere with adjacent coils
or wires.
The object of my invention is to manufacture or construct a wire or metallic
cord in which liability to fracture will be reduced to a minimum and the undue
projection of broken ends avoided.
In carrying out my invention I employ a core or centre composed of steel or
other suitable metallic wires twisted together and of sufficient strength to resist
extension. Around this twisted core or centre I weave, plait or interlace, by any
suitable mechanism, other wires composed of steel, brass, phosphor bronze, copper
or other suitable metal, or a combination of metallic wires, which are crossed under
and over each other alternately or in corresponding order in such manner as to
bind each wire down at short intervals apart throughout its entire length so that,
if a wire should break, there is not sufficient length exposed as to allow of the
broken ends projecting. The plaited or interlaced wire covering is preferably
composed of a flexible or ductile metal which will allow of sharp curvature of the
wire without liability to kink or of any of the strands to break, the core being
strong enough to support the tension that may be placed on the wire.
In some cases I weave or plait the wires together in tubular form as in the
above described covering but with a hollow centre or core.
On the annexed sheet of drawings forming a part of this specification, I shew
different constructions of wire or metallic cord made according to my invention.
In Fig. 1 letter a represents the core or centre of the wire consisting of a number
of wires twisted together right and left or cross wise and 6 the shell or covering
surrounding same and consisting of other wires plaited, laced or otherwise woven
together, or crossed under and over each other alternately or in corresponding
order, in such manner as to bind down each individual wire at short intervals apart
throughout its entire length so that if a wire should break, there is not sufficient
length exposed as to allow the severed ends to project. The wires comprising the
core a are preferably of sufficient strength to resist extension and to support the
tension that may be placed on the wire or metallic cord, whilst the wires com-
prising the covering or shell b are composed of a flexible or ductile metal which
will allow of sharp curvature of the wire without liability to kink or of the wires
to snap asunder or break.

page_text: In Fig. 2 the core a consists of wires twisted together in one direction only after
the manner of a rope or similarly to the clock wires previously used, the covering
or shell 6 surrounding same being constructed or woven as above described.
In Fig. 3 the construction of the wire or metallic cord is modified, there being
no core a therto.
The wire or cord is made by weaving plaiting or otherwise interlacing the
wires in tubular form giving a hollow cylindrical wire or cord, such construction
being sufficiently strong for many purposes such as a substitute for clock chains
or weighted cords, and possessing the advantages though not the same strength as
when made with a wire core a.
In making a hollow wire or metallic cord such as described with reference to
Fig. 3, the wires employed are preferably first stretched.
In Fig. 4 the wire covering b is provided with a core a of twine, cord or like
material or substance around which the wires are woven plaited or laced.
Any ordinary covering head or weaving mechanism may be employed for plait-
ing, interlacing or weaving the wires together to form the covering or hollow wire
or cord b, and the order in which the wires are crossed, laced, or woven, may be
varied in many ways without departing from the main feature of my invention.
The construction of the covering or hollow wire of wires composed of different
metals, or of wires plated, burnished, enamelled, lacquered, or otherwise differently
coated, will give pleasing and novel effects and designs in metallic cords for sus-
pending pictures and the like. Fibres or yarns may be introduced and combined
with the wires if desired.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
• _
Firstly. The improved manufacture or construction of wire or metallic cord as
applied for purposes such as set forth, comprising a twisted wire or like core
having a covering or surrounding shell composed of wires plaited interlaced or
otherwise woven together, substantially as herein described.
Secondly. The improved construction or manufacture of hollow wire or metallic
cord as applied for purposes such as set forth, consisting of a number of wires
plaited, interlaced, or otherwise woven together in tubular form substantially as
herein described.
