IMPROVEMENTS IN THE CONSTRUCTION OF CONTINUOUS BAR OR STRAINED WIRE FENCES
Year: 1869

page_text: LETTERS PATENT to Robert Johnson, of No. 6, Waterloo Place,
Pall Mall, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN THE CONSTRUCTION OF CONTINUOUS BAR OR STRAINED
WIRE FENCES."
Sealed the 29th June 1869, and dated the 31st March 1869.
PROVISIONAL SPECIFICATION left by the said Robert Johnson at
the Office of the Commissioners of Patents, with his Petition,
on the 31st March 1869.
I, ROBERT JOHNSON, of No. 6, Waterloo Place, Pall Mall, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF CONTINUOUS BAR OB STRAINED WIRE
FENCES," to be as follows:-
This Invention has for its object improvements in the construction of
continuous bar or strained wire fences.
In the Specification of a former Patent granted to me and dated the

page_text: 2nd March 1865, No. 592, there is described the forming of fences with
standards of a trough-like form, and for each wire or bar two holes are
formed, one through each side of the trough, the wire or bar is passed
through the holes and secured by driving a wedge down within the
trough and between the wire or bar and the bottom of the trough.
According to my present Invention I make the standards of continuous
bar or strained wire fences of a bar of iron with a flange or flanges
along one of its edges, so that it shall somewhat in section resemble the
letter L or T, or a double or single fish hook, or otherwise form the bar
with a flange or flanges, so that after the horizontal wires or bars of the
fence have been passed through holes in the stems of the standards, keys
or wedges may be driven down vertically between the horizontal bars
or wires of the fence and the flange or flanges of the standards. The flanges
may be made of such a form as to prevent the keys or wedges escaping
sideways from between the standards and the horizontal bars or wires.
The standards may in some cases be of sheet iron bent to form. By this
means the horizontal bars or wires are effectually secured to the standards.
In some cases in constructing continuous bar fences I form the horizontal
bars with curves or bends at the points where they pass through the
standards, so that the wedges or keys may lie in the recesses so formed
and be thus prevented from escaping sideways from between the flange
of the standard and the horizontal bars.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Johnson in the Great Seal Patent Office
on the 27th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
JOHNSON, of No. 6, Waterloo Place, Pall Mall, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of March, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Johnson, Her special
licence that I, the said Robert Johnson, my executors, administra-

page_text: tors, and assigns, or such others, as I, the said Robert Johnson, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercisc,
and vend, within the United Kingdom of Great Britain and Ireland, the
IMPROVEMENTS IN
Channel Islands, and Isle of Man, an Invention for
THE CONSTRUCTION OF CONTINUOUS BAR OR STRAINED WIRE FENCES," upon the
condition (amongst others) that I, the said Robert Johnson, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Johnson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
This Invention has for its object improvements in the construction of
continuous bar or strained wire fences.
In the Specification of a former Patent granted to me and dated the
2nd March 1865, No. 592, there is described the forming of fences with
standards of a trough-like form, and for each wire or bar two holes are
formed, one through each side of the trough, the wire or bar is passed
through the holes and secured by driving a wedge down within the
trough and between the wire or bar and the bottom of the trough.
According to my present Invention I make the standards of con-
tinuous bar or strained wire fences of a bar of iron with a flange or
flanges, so that it shall somewhat in section resemble the letter L or T,
or a double or single fish hook, or I otherwise form the bar with a
flange or flanges, so that after the horizontal wires or bars of the fence
have been passed through holes in the stems of the standards, keys or
wedges may be driven down vertically between the horizontal bars or
wires of the fence and the flange or flanges of the standards. The
flanges are made of such a form as to prevent the keys or wedges
escaping sideways from between the standards and the horizontal bara

page_text: Figure 1 is a section of a standard or post of a continuous bar ience
constructed according to my Invention, together with a portion of one
of the bars and the key or wedge with which it is fastened.
a, a, is the standard or post, it consists of a suitable length of
wrought-iron bar rolled to the section shown, the continuous bars 6 pass
through the web or stem of the iron standard and are fixed by keys or
wedges c. The key or wedge is driven between the flange of the
standard and the continuous bar. The flange of the standard by
overlapping the key prevents it escaping laterally.
Figure 2 shows another form where a double flange is used with two
keys for additional security; Figure 3 shows another modification
adapted to take wider keys; Figure 4 shows a standard made more
closely of the T form, the flanges having overlapping ends so that a
rectangular passage or space is left for the key on either side of the
stem; Figure 5 shows a T-formed standard with half round grooves or
channels in it for the keys; Figure 6 shows a form of standard adapted
to be made by bending sheet iron to the form required. As in Figure 1
a key on one side only is employed, it is secured by the overlapping
flange as in that Figure. The key may be of iron or wood. Strained
wire fences are similarly constructed.
It will be observed that by my present Invention but one hole is
required in each standard for each bar or wire in place of two, which
are necessary when trough-like standards are employed according to
the Invention described in my former Patent herein-before referred
to.
The forms of the standards may be varied, but what I claim is the
constructing continuous bar or strained wire fences with flanged
standards through which the bars or wires are passed, and then secured
by a key or wedge driven vertically between the bar or wire and the

page_text: flange of the standard, such flange being so formed as to prevent the
key or wedge escaping laterally.
In witness whereof, I, the said Robert Johnson, have hereunto
set my hand and seal, this Twenty-third day of September, in
the year of our Lord One thousand eight hundred and sixty-
nine.
