the County of Stafford, Iron Fencing Manufacturers. "IMPROVEMENTS IN THE
CONSTRUCTION OF IRON AND STEEL FENCING, AND IN MACHINERY FOR ROLLING
METAL TO BE USED THEREFOR TO THE REQUIRED SECTIONS, THE SAID IMPROVE-
MENTS IN MACHINERY BEING APPLICABLE ALSO FOR ROLLING METAL FOR OTHER
PURPOSES."
This Invention relates, firstly, to those uprights for fencing and hurdles which
have a stronger section of metal at the lower end thereof, that is immediately above
and extending for some distance below the ground line. The stronger section is
formed solid upon the upright by rolling instead of welding it thereto as in the
ordinary manner. The stronger section is preferably both thicker and wider than
the rest of the upright, and may be of a rectangular, channel, or other convenient
section, The uprights are formed from a bar rectangular in section, but having the
two upper edges chamfered off. The bar in a heated state is passed first through a
pair of rolls, one of the rolls having a plain groove, and the other a plain collar,
except that for a part or parts of the circumference of the roll the collar is
reduced in diameter. The bar is thus reduced in thickness except for the distance
The bar is then
at regular intervals where the collar is reduced in diameter.
passed through a plain part of the rolls if a rectangular section of the enlarged
part is required, and the weight of the top roll draws the thinner part of the bar
through, but the thicker part is rolled as much thinner as may be desired (but
preferably thicker than the main part of the bar), and at the same time spread.
out wider by the action of rolling. If a channel shaped section of the strong part
is required, the bar after the first rolling as before described is passed through
a plain groove in the roll of the width the thickened parts are desired to be.
bar is guided through the middle of the groove and a collar narrower than the
groove pressing upon the thinner parts of the bar (by reason only of the weight of
the roll) draws the bar through, but rolls the thickened parts thinner, at the same
time forcing the metal out to the sides of the groove, and forcing up a ledge or
flange at either side of the collar. The bars are rolled in lengths with the stronger
parts at intervals as required, and the lengths for the uprights are afterwards cut
off

-And-this-Invention-relates, secondly,-to-channel iron or steel bars and uprights
for fencing and hurdles. The channel iron or steel is rolled with solid parts therein
at intervals as required, the said solid parts making the metal rectangular in
section (or as nearly so as practicable) at the points where they occur. The said
solid parts are rolled within the channel in positions where extra strength, or a
rectangular shape; or both are required or-preferred, for instance, where horizontal
bars pass through uprights. By the use of channel iron or steel constructed as
aforesaid considerable lightness in the uprights and bars is secured together with
great strength at the joints.
