firm of Bruce and Still of Liverpool in the County of Lancaster Galvanized
Iron Manufacturers for an Invention of "IMPROVEMENTS IN POLES OR
STANDARDS MORE ESPECIALLY USEFUL FOR WIRE FENCING "
PROVISIONAL SPECIFICATION left by the said William Thomas Clarke
Bruce and Arthur Still at the Office of the Commissioners of Patents on the
18th December 1883.
WILLIAM THOMAS CLARKE BRUCE and ARTHUR STILL of the firm of Bruce

IMPROVEMENTS IN POLES OR STANDARDS MORE ESPECIALLY USEFUL FOR WIRE
"
FENCING
"
In wrought iron standards as at present usually constructed, there are salient
angles which are liable to injure cattle, while if these are avoided the expense of
manufacture is much increased.
Now my invention is designed to form a cheap, strong, substantial standard,
without salient angles. It consists in forming a tapering or parallel tube, preferably
the former, of sheet iron, the edges being riveted or turned over and galvanized.
This tube is then placed between dies and the seam and opposite side pre-sed
together leaving two equal tubes on each side. The part pressed. t gether is then
perforated for the wire, and in some cases bolted or riveted. A cap surmounts the
standard in the usual manner, and is fastened to it by a bolt, pin, or rivet through
the thin central neck of the standard. This standard can be used for other
purposes where firm light standards are required whether in engineering, telegraphy,
or farming. It can be formed in other ways than that set forth, but the 'irode
of manufacture above described will be found the cheapest and best for most
purposes.

the said William Thomas Clarke Bruce and Arthur Still in the Patent Office
on the 18th June 1884.
WILLIAM THOMAS CLARKE BRUCE and ARTHUR STILL of the firm of Bruce
and Still of Liverpool in the County of Lancaster Galvanized Iron Manufacturers
"IMPROVEMENTS IN POLES OR STANDARDS, MORE ESPECIALLY USEFUL FOR WIRE
FENCING"
In wrought iron standards as at present usually constructed, there are salient
angles, which are liable to injure cattle, while if these are avoided the expense of
manufacture is much increased.
Our invention is designed to form a cheap strong substantial standard without
salient angles, and consists of a hollow pole or standard formed of sheet iron
compressed together at two opposite sides, so as to be in cross section of a form
resembling the figure 8.
It is best described by aid of the accompanying drawings, in which Fig. 1 is an
elevation of pole or standard made in accordance with our invention. Fig. 2 a plan
view or cross section of same at the largest end.
In carrying out the invention we form a tapering or parallel tube (preferably the
former) of sheet iron, the edges being in some cases riveted or turned over or they
may be merely laid together as shown, and the whole is then galvanized. The
galvanizing after the tube is made helps to stiffen and secure the joint of the two
edges. This tube is then placed between dies and the seam and opposite side
pressed together, forming two approximately equal tubes A. B. one on each side,
the two being joined together by a flattened portion C of the tube at each side.
This part C is then perforated with holes E at the required distances apart from
the wires. In some cases bolts or rivets may be used to secure the two edges of O
together. A cap F surmounts the standard in the usual manner, and is fastened to
it by a bolt, pin or rivet G, or preferably by the top wire running through the thin
central neck of the standard. This standard can be used for other purposes where
firm light standards are required whether in engineering, telegraphy or farming-
It can be formed in other ways than that set forth, but the mode of manufacture
above described will be found the cheapest and best for most purposes.
Having now described our invention and the best mode known to us of carrying
it into effect, we wish it to be understood that we do not claim broadly the use of
hollow metal or sheet iron standards or poles, but that what we believe to be new
and desire to protect by letters patent is :-
A pole or standard for wire fencing and other purposes in the form of two tubes
contiuent or joined together, constructed out of sheet metal substantially in the
manner described.
In witness whereof I the said Arthur Still for and on behalf of myself and the
said William Thomas Clarke Bruce have hereunto set my hand and seal this
seventeenth day of June in the year of our Lord one thousand eight hundred and
eighty four.
