IMPROVEMENTS IN FENCING WIRE
Year: 1884

page_text: I FREDERICK WILLIAM BRAMPTON of number 14 Oliver Street Birmingham
in the County of Warwick Manufacturer do hereby declare the nature of the
said invention for "IMPROVEMENTS IN FENCING WIRE" to be as follows that is to
say:
My Invention has for its object improvements in fencing wire by which I am
enabled to impart to single strands of wire or solid sections whether barbed or
plain a certain amount of elasticity which prepares such wire for violent changes
of temperature or unusual strains of any kind thus increasing the durability and
lessening the need for watchful care and repairs.
Elasticity is at present obtained by twisting together two or more strands of
thin wire which is necessarily very expensive and not so stiff as the same weight
of metal. concentrated in one section whether round or otherwise and besides the
two or more light strands are more expensive apart from the cost of twisting...
To render solid section whether barbed or plain elastic I produce a corrugation
or-wave along the entire length of the strand and this corrugation may be an'
alternating one that is to either side and upwards and downwards or diagonally
indeed in any direction radial from the centre of the axis of the strand which
I produce as the wire leaves the rolls or inachine by a suitable anvil or matrix with'
plungers fixed round the axis, of. the wire in number according to the variety of
corrugations required.
In other cases and especially in the case of plain wire without barbs I pass the
wire through a pair of grooved rolls of the drum and force it, through a steel plate'
or die which moves as an eccentric. The amount of throw or eccentricity of this'
plate regulating the wave or twist or coil of the wire and the length, of the said
wave or coil is also regulated by the distance of the said die or plate from the rolls
or machine through which the wire passes.
The wire is not necessarily twisted in its fibres or body up on its own axis'in so
passing through the die but the same centre line may be preserved along the whole
length if so desired. This single strand fence wire so twisted possesses the extra
advantage of appearing larger to the eye than straight wire which is of con-
siderable importance when it can be done at only a slightly increased cost over the
solid wire as it appears much more formidable as a fence to the eye.

page_text: I FREDERICK WILLIAM BRAMPTON of N° 14 Oliver Street Birmingham in the
County of Warwick Manufacturer, do hereby declare the nature of the said
invention for "IMPROVEMENTS IN FENCING WIRE," and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement that is to say :-
My Invention has for its object improvements in fencing wire by which I am
enabled to impart to single strands of wire or solid sections a certain amount of
elasticity which prepares such wire for violent changes of temperature or unusual
strains of any kind thus increasing the durability and lessening the need for
watchful care and repairs.
Elasticity is at present obtained by twisting together two or more strands of
thin wire which is necessarily very expensive and not so stiff as the same weight
of metal concentrated in one section whether round or otherwise and besides the
two or more light strands are more expensive than one section apart from the cost
of twisting.
To render solid sections elastic I produce a corrugation or wave along the entire
length of the strand and this corrugation may be an alternating. one that is to
either side upwards and downwards or diagonally indeed in any direction radial
from the centre of the axis of the strand which I produce as the wire leaves the
rolls or machine.by a suitable anvil or matrix with plungers fixed around the axis.
of the wire in number according to the variety of corrugations required.
In making the spiral wire I pass it through a pair of grooved rolls off the drum
and force or draw it through a steel plate or die which moves as an eccentric. The
amount of throw or eccentricity of this plate regulating the wave or twist or coil
of the wire and the length of the said wave or coil is also regulated by the
distance of the said die or plate from the rolls or machine through which the wire
passes.
This wire is not necessarily twisted in its fibres or body upon its own axis in so
passing through the die but the same centre line may be preserved along the whole
length if so desired This single strand fence wire so treated possesses the extra
advantage of appearing larger to the eye than straight wire which is of con-
siderable importance when it can be done at only a slightly increased cost over the
solid wire as it appears much more formidable as a fence to the eye. In the case
of public parks and private estates the appearance is greatly improved as compared
with either solid straight wire or compound strands.
In order that my invention may be more clearly understood and carried into
practice with greater facility I have appended hereunto a sheet of drawings
showing two examples of my new fencing wire which I will now further explain
by reference thereto.
wave in
Figure 1 is a side elevation of a fence made from wire which is turned in
a continuous siries of coils forming indeed a continuous spiral or
appearance.

page_text: This class of fencing would present in every direction the same appearance and
as will be seen looks much more formidable as a fence than plain wire, It also
affords sufficient elasticity for any climate without further provision such as elastic
junctions and other provisions which have been adopted to obtain elasticity in other
kinds of fencing.
The straining Post A and intermediate post B do not form any part of my invention
neither do the straining eye bolts C.
Figure. 2. is a side elevation of one example of my corrugated wire fencing
which may be corrugated or waved in any direction upwards, downwards sideways
or diagonally and the corrugations may be of such a kind as to present almost
exactly the same appearance as the spiral in Figure 1 that is the curves of the
corrugations or bends might die into each other instead of a straight piece inter-
vening between each bend. It will thus be clearly understood that my invention
applies to single strand fencing wire worked into a spiral form or twist of such a
nature that on every side it presents to the eye the same appearance or to single
strand fencing wire waved or bent with a series of continuous bends in any radial
direction from its centre.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
First The improvements in plain fencing wire of a solid single strand turned
or worked into a spiral, substantially as and for the purpose herein set forth.
Second The improvements in fencing wire of a solid single strand with a
series of corrugations formed along the same as and for the purpose herein set
forth.
