PROVISIONAL SPECIFICATION.
Improvements in Barbed or Armed Fencing or Railing.
We, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, and BERRY LIMITED, of Angle Lane, Northampton, in the
County of Northampton, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to that class of barbed or armed fencing or railing which
is formed from flat metal bars or ribbons by punching pieces out of one or both
edges and twisting the bar or ribbon so as to cause the barbs or spikes to project all
round.
The object of our invention is to roll the said bar or ribbon to such a section and
punch such piece out of it, that when the bar or ribbon has been twisted, a wire,
having barbs or spikes projecting all round at regular and short distances, is
produced, which forms a more effective, stronger and neater barbed or armed
fencing than hitherto has been in use.
To this end we roll the metal bar or ribbon used for the fencing or
railing to
wedge or taper section with or without a beading at the thick edge, on one or both
sides. The part from the thin edge to the beading or a part of equal width when
the said bar or ribbon has no beading, we form into pyramidical barbs or spikes
by punching trapezoidial pieces out of the same at regular distances.
The barbed or spiked bar or ribbon we then heat which facilitates the twisting
of the same and owing to the special form of pieces cut out, the displacing of the
barbs or spikes axially at such short and equal distances that it will afford no grip
without injury.

Improvements in Barbed or Armed Fencing or Railing.
We, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, and BERRY LIMITED, of Angel Lane, Northampton, in the
County of Northampton, Manufacturers, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to that class of metal barbed or armed fencing or railing

page_text: which is formed from flat metal bars or ribbons by punching pieces out of one or
both edges and twisting the bar or ribbon so as to cause the barbs or spikes to
project all round.
The object of our invention is to roll the said bar or ribbon to such a section
and punch such pieces out, that when the bar or ribbon has been twisted, a wire or
bar having pyramidical or wedge shaped barbs or spikes projecting all round at
regular and short distances is produced, which forms a more effective, stronger and
neater barbed or armed fencing than hitherto has been in use.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1, 2 & 3 being perspective views of various sections of barbed or armed
metal bars or ribbons, Fig. 4 of a bit punched from the same, and Fig. 5 of a
finished piece of barbed or armed fencing or railing in accordance with our
invention.
In carrying out our invention, we roll the metal bar or ribbon used for our
improved fencing or railing, to wedge or taper section without beading at its
thick edge, see Fig. 1, or with a beading a thereon, as shown in Figs. 2 & 3. The
flange or part from the thin edge to the beading a, or a part of equal width when
the said bar or ribbon has no beading, we form into pyramidical barbs or spikes b
by punching trapezoidial pieces, see Fig. 4, out of the same as regular distances,
or in lieu of trapezoidial pieces rectangular picces may be punched out and wedge
shaped barbs or spikes thereby produced as will be readily understood.
The barbed or spiked bar or ribbon thus produced we then heat, say in a gas
furnace, so as to allow of being readily twisted by hand or mechanical means and
owing to the special form of the pieces c cut out, which produce a space between
the base of each two barbs or spikes 6, the latter can be displaced axially at such
short and equal distances that the fencing or railing produced will afford no grip
without injury.
our said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, we declare that what
we claim, is:
1st. In the manufacture of barbed or armed metal fencing or railing, a bar or
ribbon of wedge or tapered section having pieces punched out which leave
pyramidical or wedge shaped barbs or spikes, all substantially as set forth.
2nd. The bar or ribbon specified in the preceding claim, twisted in such a manner
that the pyramidical or wedge shaped barbs or spikes thereon are displaced around
the continuous part or beading at short and equal distances from each other, all
substantially as set forth.
3rd. An improved barbed or spiked metal fencing or railing, consisting of a
central part or core, with pyramidical or wedge shaped barbs or spikes projecting all
round the same in close proximity to each other, all substantially as set forth.
