ROBERT JOHN GEORGE, of Swansea, in the county of Glamorgan, Member of
the Institute of Civil Engineers, "IMPROVEMENTS IN THE CONSTRUCTION OF
METALLIC FENCING (Partly a communication to me from abroad by Edward
Monson George, of Sutna, Central India, Civil Engineer, and partly the result of
invention made by me)
The subject of this invention communicated to me by my brother Edward
Monson George, of Sutna, Central India, and practically carried out by myself
relates to an improved construction of metallic fencing, very light in weight and
very rigid when fixed, and suitable for enclosing fields and railway and other
property, and for purposes where a line of fencing is required.
I form the posts of the improved fence of wrought iron tubes, the lower ends of
which can be bent and flattened, or fitted into cast iron bases or ground plates to
obtain a hold in the ground.
Holes are drilled through these tubes to receive the wires either single or in
strands which are locked when strained by suitable wedges dropped into the tubes,
wedging the wires firmly against the interior of the tubes.
Ornamental or other caps may be used to fit on the tops of the tubes with separate
wedges to secure the upper wire, or simple caps may be fitted on, which close the
tops of the tubes and at the same time wedge the upper wire.
The straining posts consist of a cluster of tubes (usually three arranged in
tripod form) fitting into sockets in a base or ground-plate and provided with swivel

page_text: tightening bolts to strain the wires. These or the ordinary posts may be kept
vertical when required by wires attached to pegs anchored in the ground.
The straining posts can be left permanently in position at the completion of the
work, or be removed if thought desirable, as without them the fence will remain
rigid when strained and wedged. In this case, in setting up the fencing, after a
length has been strained, I anchor the last standard and then shift the straining
post, connect the loose ends of the wire and tighten by the shifted straining post
set up in another place.
The straining posts may be used as terminal, tie or angle posts by passing the
wires through holes drilled in two of the tubes and wedging as before.
When setting up the fence, the lowest wire is first passed through the posts and
strained and wedged, and the others successively treated, finishing at the top wire.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Robert John George in the Great Seal Patent Office on the
2nd March 1883.
ROBERT JOHN GEORGE of Swansea in the county of Glamorgan Member of
the Institute of Civil Engineers "IMPROVEMENTS IN THE CONSTRUCTION OF
METALLIC FENCING (Partly communicated from Edward Monson George, of
Sutna, Central India, Civil Engineer, and partly the result of invention made by
myself)
The subject of this Invention as communicated to me by my brother Edward
Monson George, of Sutna, Central India, and practically carried out by myself
relates to an improved construction of metallic fencing, very light in weight, and
very rigid when fixed, and suitable for enclosing fields, and railway and other
property, and for purposes where a line of fencing is required.
I form the posts of the improved fence of wrought or cast iron tubes, the lower
ends of which can be bent and flattened or fitted into iron bases or ground plates
to obtain a hold in the ground. The iron cross stays shewn may be used when
additional hold is required.
Holes are drilled through or cut out of these tubes to receive the wires single or
in strands, either plain or barbed, which are locked when strained by separate
wedges dropped into the tubes, and driven tight by a bar or rammer passed down
the tubes thereby wedging the wires firmly against the interior of the tubes.
Ornamental or other caps may be used to fit on the tops of the tubes. The
straining posts consist of a cluster of tubes (usually three arranged in tripod form)
fitting into sockets in a base or ground plate, and provided with swivel tightening
bolts to strain the wires. These, or the ordinary posts may be kept vertical
when required by wires attached to pegs anchored in the ground or by means of
struts,

page_text: In these figures A represents the standard, B the wedges, C the wires. In the
compound straining posts A are the standards secured together by the plates D D
and with their bottom ends usually fitted into base plates E and fitted at their tops
with caps F.
In setting up a line of fencing the wedges may be used for each wire or for
alternate wires or for alternate or occasional posts according to the strength of
fence desired.
I have shewn at Fig. 10 a long wedge but I do not claim this and merely shew
it as an adjunct to my Invention.
When setting up the fence and standards with holes drilled for the wires are
used the lowest wire is first passed through the posts and strained and wedged,
and the others successively treated, finishing up with the top wire.
In cases where the holes are slotted out of the tubes the wires are first strained
and then put in the slots and wedges dropped and driven by the rammer to pass
outside them.
For gate posts large iron tubes are used and the wires are wedged inside.

page_text: By this means gate posts can be put up in a fence and the wires strained through
them, the gates being subsequently fixed in place by cutting the wires and the loose
ends may be wound round the posts. The various details of the fencing may be
readily understood from the drawings. The wedges may be made of cast, or wrought
iron or other suitable material.
The drawings Figures 17 and 18 shew the compound straining post used also as
an angle post. The size and strength of all posts, wedges and other appurtenances
must be adapted to the purpose required and I do not bind myself to the size or
mere exact details shewn. I do not claim the mere use of tubes for fencing nor
the cutting of slots to insert the wires nor do I claim the use of anchors, struts,
tightening bolts or iron bases or stays neither do I claim the mere application of
a wedge to fasten a fence wire, but
.
Having now particularly described and ascertained the nature of the said Inven-
tion and the manner of performing the same I would have it understood that I
claim on behalf of myself and the said Edward Monson George,
Firstly. The improved metallic fencing consisting in the combination of fixed
(perforated or slotted) tubular standards having their ends bent and flattened or
fitted in base plates, with separate wedges dropped down such and driven by a
bar, rammer or the like to secure the wires substantially as described and
illustrated in the accompanying drawings.
Secondly. The improved compound tubular straining or angle-post formed by
the tubes A A A secured together by tie-pieces D D D and base E in combination
with the separate wedging of the wires inside such tubes substantially as described
and illustrated in Fig 17 and 18 of the accompanying drawings.
In witness whereof I the said Robert John George have hereunto set my
hand and seal this Second day of March in the year of our Lord One
thousand eight hundred and eighty three. .
