An Improved Machine for the Manufacture of Barbed Wire for
Fencing.
I, ARTHUR EDMUND GORSE of West Bromwich in the County of Stafford England,
Machinist do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :—
My invention has for its object an improved machine for the manufacture of barb
wire for fencing by which I am able to obtain in a single strand of wire barbs of any
lengths and at any intervals of the most substantial kind and in a comparatively simple
and inexpensive manner.
In order that my invention may be clearly understood and more easily carried into
practice I have appended hereunto four sheets of drawings upon which I have fully
illustrated the nuture and working of my said invention.

The outline of my machine consists of the bed W upon which is mounted the driving
shaft X which is connected with the cross shaft X' which in turn operates the longi-
tudinal shafts Z and Y by means of the bevel wheels and and from these three
shafts X, Y and Z the whole of the movements required are obtained.
For the purpose of simplifying the description the machine may be said to be

page_text: divided into three main parts, 1, 2, amit as indicated on Figure 1 of the drawings the
No. 1 part consisting of the arrangement by which the wire is ent off into lengths and
a loop formed at the end as seen at Figure 5. In No. 2 part the wire is bent into the
shape shown by Figure 9 and in part No. 3 the knot is tightened into the form shewn
by Figure 12 or 18.
The wire A is fed into the machine through the straightness from the drum by any
ordinary feed slide A which in the present case is operated by a roller working in a
groove in the cam A' on the shaft X. The wire when stationary is gripped by the
lever B during which a length is cut off by the diagonal cutter C which is operated by
the cam on the shaft Y as shewn in Figures 17, 18, and 19. This cutter (is
mounted in the slide o' which slides in the main part of the lever so as to have lateral
ndjustment by means of the screw e and is also provided with the adjustable screws
and which are made to operate upon each end of the plate for the purpose of
increasing or diminishing the amount of angle at which the wire is severed to form
the barhed end. The handle being provided at the end of the lever to enable the
wire to be cut off by hand when the machine is not in operation.
The earringe is made to slide in the groove W which is formed in the hed
to receive it the travel of the carriage being effected by means of a roller working
in the groove' of the cam. which is mounted upon the end of the shaft X
from which the earringe is connected by means of the rod and pivotted rod
Figure 2 the rod d being connected to the lever at the bottom of the rising
and falling serow rod which serew rod is provided with the bent head d so
that as the carriage is drawn for sard in the direction of the arrow the head dis
lowered into the position shown in Figure 20 and 21 und the wire having been
fed on to the earringe & cut off as before described, the head d falls upon the
wire retaining it in position. Before the earringe advances the sliding bolt H
having the sunk hollow his pressed under the wire by means of the cam H¹ while
the mandril bolt F is allowed to advance over the wire by the cams the advance
being effected by means of the spring. The bolt F is mounted in the rising and
fulling slide which slide is kept up by any suitable spring and depressed by
the lover which is acted upon by the cam The depression of this bolt f
into the hollow bolt H thus lends the wire as shown in Figure 22 causing it to
take the form shewn by a Figure 3. The travelling carriage D is held in position by
the sliding bolt E which is operated by the cam E. The wire is caused to take
the form shewn by Figure 4 by means of the crank lever G the crank centre g
of which is pivotted in the slide g the other end of the crank being provided with
the roller so that as the slide is operated in the direction of the arrow
Figure 22 a roller on the rod working in a groove in the cam G¹ on the
shaft, the roller g is caused to travel up the incline g thus depressing the
tool G until the wire is bent around the mandril into the shape shown by at
Figure 4 after which the mandril F is withdrawn by the cam and the
bolt His pressed still further forward by the cam H until the projection *
presses the bent head of the wire over against the die formed upon the
carriago until the bent head of the wire is caused to take the form slewn in
plan at a Figure 5. The bolts El and E are then withdrawn by means of any
suitable springs and the carriage D travels forward as before described until the
head of the wire A is threaded on to the stem a of the wire which has
previously travelled up as shown by Figure 6 and is gripped near the head at the
point Figure 6 by the grippers at which time the wire is released from the
traveling carriage by its return to repeat the action. The and a of the previous
wire is kept stealy and in position to receive the head of the next wire by means
of the steadying fork Go Figure 26 which is pivotter on to the slide support G"
the centre pivot g being of hexagonal shape one face of which receives the end
ol the spring g" by which means the fork is kept in position until the carriago
comes forward when it strikes the fork up into the position shewn by dotted lines
in which position it is retained by another face of the hexagon receiving the spring
where it remains until depressed as hereafter described. The bolt K is then

page_text: pressed forward by the cams K' until the flange k passes in between the two
wires and slightly separates them after which they are gripped at the point að
Figure 6 by the grippers L which are operated by the cams L' the grippers being
then withdrawn by means of suitable springs. The bolt K is then operated still
further by its cam until it bends over the wire into the position shewn in Figure 25
and by plan in Figure 7 after which the holt K is withdrawn by a suitable spring.
The bolt M is then forced forward by its cam and is provided with the stop m² to
keep the wire in position while the split mandril N is forced forward between the
two wires as seen in Figures 25, 27. and 28 and the lever O is depressed by the cam O'
on the shaft Z until the end a' of the wire is bent down over the mandril N into the
position shewn by Figure 8 and by dotted lines in Figure 27 the lever at the same
time in conjunction with the bolt M gripping the one wire while the end of the other
wiro i bent up from underneath by the cranked lever P Figure 2 the action of which
corresponds exactly with the action of the cranked lever G before described the slide p*
being operated by the grooved cam P¹ through the levers p² and rod p².
The previous knot is then gripped by the travelling grippers Qas hereafter described
and the grippers L are withdrawn leaving the grippers M and O gripping the wire
until the two wires are drawn tighter together as shewn by Figure 10 after which the
grip of M and O is relaxed as afterwards described and the wire is then carried
forward until the next knot is in position for being gripped by the travelling grippers Q
the relaxing of M and O being effected by means of the arrangement of the secondary
cam and lavoro as seen in Figure 30 the wire A is gripped merely by the strength
of the spring of so as to allow of the end of the wire being withdrawn through the
grippers M and O the lever O afterwards taking the position shewn in Figure 27
again a projection o Figure 1 and 28 is formed upon the lever O for the purpose of
depressing the mouth of the fork Gapon the end at of the wire to steady it ready
for the next wire which the carrier D has to thread upon it.
The lever is mounted upon the shaft o the operating end being shewn broken
away in Figure 1 so as not to confuse the drawings. The grippers are mounted upon
the lever which is pivotted to the bed W at which lever is operated by the side of
the cam
in the one direction and has a suitable spring to operate it in the other
direction. The face of the cam Q' is formed to operate the gripper q upon the knot
of the wire the gripper Q being a fixture upon the lever a suitable spring being
arranged in any convenient position for opening the grippers when the cam allows
of it.
The grippers R are then withdrawn from gripping wire at the rear of knot by means
of a suitable spring and the grippers S grip the wire in front of the knot while the
travelling gripper Q returns to bring up another knot after which the grippers Sagain
open to allow the knot to be pushed through which is offected by the travelling
grippers Qbringing up the next knot thus pushing the previous one on in front until
it arrives in the position opposite the fingers U which are forced forward by the
cams U until they press the barbed ends out as shown in Figure 33 after which they
are withdrawn by suitable springs and the barbed ends all and a" are gripped by the
vertical grippers V and V' as shown in Figures 34, 3 and 36. The top and bottom
tools of the gripper V for gripping the barhed end all of the wire are mounted upon
the travelling carriage T the bottom tool being fixed to the bed of the carriage and
the top tool being fixed at the one end in the lever the other end of which is
pivoted to the support which is in turn mounted upon the carriage T.
The top
and bottom tools of the gripper V1 for gripping the barbed end a of the wire are
fixed stationary upon the bed and do not travel the bottom tool being fixed to the
bed W of the machine and the top tool is fixed in the lever which is pivotted to
the support on the bed W. The pair of horizontal grippers T are also mounted
upon the carriage T for gripping the wire in the position shown the tools being
mounted in the levers which are pivotted to the travelling carriage T at and
provided at the reverse end with the rollers which as the carriage T travels in the
direction of the arrow in Figure 35 are wedged apart by the wedge piece T' thereby
gripping and pulling the wire at T the travel of the carriage being effected by the

page_text: roller upon the carriage working in the groove in the cam T upon the shaft X.
The vertical grippers V and V are operated by the pivotted levers and from the
coms Va the top grippers being kept up when not gripping by means of suitable
suspending springs. "It will thus be seen that while the rear end of the wire is gripped
in a fixed position by the grippers S and the barb a" is gripped in a fixed position by
the grippers V, the front part of the wire is gripped by the travelling grippers T
and the barb a by the travelling grippers V by which means the knot is drawn
tightly into the shape shown by A or A Figures 12 and 18 the difference being
effected by a slight variation in the position of the vertical grippers V and V₁.
When the travelling carriage T is ready to make its return journey the wedge
shaped pieco which is pivotted at eº and kept down by the spring 110 is tilted up
clear of the rollers by means of the projection " on the cam T thus allowing the
spring to open the grippers while the knot passes between them. The top tools
of the vertical grippers and Vare mude to lap into the bottom tools which aro
made to receive them so that as the top tool is depressed upon the wire barb onds a"
and the ends are bent more or less at right angles to the wire as may bo
desired or arranged for by the shape of the tools.
It is evident that my machine is applicable to tieing metal together for purposes
other than for fencing and that the motions here shown may be somewhat varied
by using equivalents.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1st. The machine herein set forth consisting of the cutting, carrying, bending
tieing and tightening motions substantially as and for the purpose herein set forth and
shewn upon the drawings.
2nd. The travelling, gripping carriage 1 for holding the wire while being bont with
its accompaning parts d'and if substantially as herein set forth and shown upon the
drawing.
3rd. The means for bending over the wire into the loop shewn by Figure 4 consisting
of the t of G slide cranked lever g³ roller g' and incline g substantially as herein
set forth and shown.
4th. The means for threading and forming the second loop of the knot consisting
of the fork (split mandril № grip M and lovers O and P'combined and operated
substantially as herein set forth and shewn.
5th. The mean for hending the barhed ends over and tightening the knot consisting
of the fingers stationary grippers S and Vin combination with the travelling
grippers V and T substantially as herein set forth and shown upon the drawings.
