or Apparatus for Manufacturing the same.
1, HENRY BÖNTEN, of the firm of H. and F. Bönten, of Suffolk House, 5 Lawrence
Pountney Hill, in the City of London, Merchants, do hereby declare the nature of iny
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to manufacture barbed wire fencing in an improved
manner, securing simplicity of construction, efficiency, and cheapness in the
manufacture.
In carrying out my invention, I make use of rolled or drawn wire, of iron, steel, or
other suitable metal, and having grooved sides, preferably of a triangular section ;
but I sometimes use wires of other sectional forms, as square, pentagonal, hexagonal,
elliptical or circular.
I twist three of such wires together, and thereby form a three-ply fencing wire, into
or between the strands of which I fix barbs having three points, of an arrow-head
form, made of sheet metal, and which barbs are firmly held and secured by the
strands.
•
The triangular shape or section forms a light description of wire, and the three ply
formation of the same wire enables the three-pointed barbs to be held more firmly
than ordinary round wire. Moreover great strength and stiffness are ensured, and a
serviceable, effective and cheap fencing is produced.
And in order that my said invention and the machinery or apparatus for manu-
facturing the same, be particularly described and ascertained, reference is hereby made
to the accompanying drawings, in which similar letters of reference indicate
corresponding parts.
Fig. 1 is a sectional elevation of my invention. Fig. 2 is a front view; and
Figs. 3 and 4 are detail views, and Fig. 5 is a section shewing the manufactured
article.
a a a are three druns, mounted in frames or cradles bbb, each drum being capable
of revolving on its own centre, upon the axle », and having ordinary strap brakes
fitted to the grooved pullies w, for regulating the tension of the unwinding wires .

page_text: These drums, when completely unwound, can be readily taken out, and replaced by
full drums, so as to facilitate the working of the apparatus.
The three cast iron cradles bbb, which carry the drums, are caused to revolve upon
their longitudinal axes by means of the pinions y which gear into the stationary
wheel z, with internal teeth. The front ends of the cradles are provided with steel
conical bushes c, for guiding the wires. The cradles are supported, at their back
ends by the bosses d, and at their front ends, by the cast iron wheel, fitted with
bosses g. e is the driving pulley.
The main shaft is supported at the back end by the cast iron pedestal i. This
pedestal also carries the stationary wheel, having internal teeth. The casting kis
keyed to the front end of the main shaft, and revolves therewith in the conical
bearing formed in the pedestal j. The conical openings in the casting k, are arranged
to suit the direction of the wires, as they unwind from the drums. The stationary
internal-toothed wheel m is bolted to the pedestal j. is the apparatus for inserting
the barbs. This apparatus is bolted to the casting k, and revolves therewith. This
portion of my invention is shewn enlarged in Figs. 3 and 4. It consists of a box t,
capable of holding about 200 barbs, which box may be removed, when empty, its
place being supplied by a full one. The box is fitted with a spring which presses the
barbs forward towards the piston r. The revolution of the casting and apparatus
causes the revolution of the pinion a, gearing with the teeth of the fixed wheel m.
The spindle o of the pinion n carries a worm, which drives the worm-wheel p; this
worm-wheel carries the cam y, the revolutions of which impart reciprocating motions
to the piston r. Each time the piston is pressed forward it drives one of the barbs
between the strands, which close upon it and forcibly hold it, at suitable intervals, as
shewn in Section in Fig. 5, in which 1 is the barb, and 2, 2, 2, are the wires.
As arranged on the drawings, with one can q, the barbs would be inserted in the
wire fence six inches apart; but by adding another cams (shown by dotted lines) the
barbs may be inserted 3 inches apart. Other distances may be arranged with
obvious modifications.
The finished wire is carried over the grooved wheel u fitted with pins, so that the
barbs may not be injured, as they pass over it.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. The manufacture and use of barbed wire fencing, consisting of three strands of
wire twisted together, and having arrow-headed barbs inserted therein, at suitable
distances apart, substantially as herein before described, and shewn on drawings.
2. The general construction combination and arrangement of machinery for
twisting and otherwise manipulating barbed wire fencing, of the description aforesaid
substantially as hereinhefore described and shewn on the drawings.
