HUNTER HENRY MURDOCH, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent. "IMPROVEMENTS IN THE MANUFACTURE OF BARBED FENCE WIRE
AND IN MACHINERY TO BE USED IN THE SAID MANUFACTURE." A. cominunication
from abroad by Henry William Putnam, of Bennington, in the State of
Vermont, in the United States of America.
The object of this Invention is the manufacture of barbed fence wire, such as is
represented in Figure 1, which is a top or plan view of the same; Figure 2 is a
longitudinal section on line A, B, Figure 1; Figure 3 is a bottom view of the wire
shown in Figure 1.
In the Drawings the parts marked A represent the main fence wire, about which
the barbed wire is secured to form the coils B projecting under C, and barbed or
pointed ends D. This barbed fence wire or fencing is made by a continuous
process or operation as fully herein-after described. It is formed from wire drawn
from two separate coils or reels, the motion of the barbed wire as it is fed forward
being at right angles to the main wire A, and the portion which forms the coil B,
and one of the projecting barbed ends C, D, is run over and past the end of the
main wire A as indicated at E, in dotted lines, Figure 1, when the mechanism of
the machine holds the main wire A from turning or moving forward, and the
mechanism also holds the barb wire E from turning or moving backward or forward
while a presser foot rests upon the barb wire at the point a. A rotatory shaft
through which the main wire passes now commences to revolve, and a finger pro-
jecting from the end strikes the end E of the barb wire at the point b, and carries
it down and under the main wire A, and by means of an inclined guide the wire
וע...

page_text: end E is forced to move back so as to wind about the main wire A in the form of a
screw, and consequently it comes up back of the uncut portion of the barb wire F,
the coiling shaft being arranged so that it moves back as the end E is wound back
upon the main wire A.
After the first revolution the end of wire E is guided back
by the previously formed spiral of the coil. The winding finger stops after coiling
the end E about the main wire, as shown in full lines, Figure 1. The cutter now
comes forward and severs the coil B from the main barb wire F as shown at G in
full and dotted lines, Figure 1. The main wire at the same time the cut is being
made is moved along in the direction indicated by arrow 2, and the newly formed
coil B is carried along and carried between a pair of compressing dies, by means of
which coil B is compressed upon two sides with great power and forced
upon the main wire A, whereby the separate strands of the coil 1, 2, and 3, are
flattened upon their outer, upper, and under sides, whereby the said strands are
forced into the main wire, causing spiral indentations upon two sides of the main
wire. By this mode of construction the barbed wire or fencing shown in the
Drawings can be made with great expedition and facility, while the barbed
ends C, D, are held in rigid position by means of their coils B having been com-
pressed about and set into indentations in the main wire, as shown and described.
By this mode of construction each separate strand of the coil presents a resisting
force when power is applied to rotate the barbed ends about the main wire, con-
sequently animals running against or pressing upon barbed ends C, D, will be
pricked and turn back.
There being great uniformity in the construction and securing of the coil B and
barbed ends C, D, about the main wire A, the barbed ends always projecting
horizontally above one side of the main wire, the barbed fence wire or fencing can
be wound upon a reel or cylinder as it passes from the machine, and in such
manner as not to have the barbed ends of one strand entangled or marled up with
another strand, or the barbed ends thereon. This is owing to the fact that the
different barbed ends are separated by a distance equal to the diameter of the
main wire and the diameter of the barbed wire. This is a very important feature
of the Invention since it enables the wire to be wound and unwound as readily as
if the barbs were not combined with the main wire.
The machine to which reference has been inade is shown in the Drawings, in
which Figure 4 represents a top or plan view of the said machine; Figure 5, a side
view; Figure 6, a vertical central section on line A, B, Figure 4, looking in the
direction of arrow 1, Figure 4.
Figure 7 represents upon an enlarged scale a plan view of part of the machine as
will be herein-after explained.
Figure 8 represents a side view of part of the rear portion of the machine looking
in the direction of arrow 1, Figure 4, as will be herein-after explained.
Figure 9 represents upon an enlarged scale a top or plan view of a section of the
barbed wire or fencing made by the said machine; the section showing four of the
barbs in position upon the main wire as they are left by the machine; Figure 10
represents a cross section of the barbed wire or fencing on line C, D, Figure 9; and
Figure 11 represents a longitudinal section of the barbed wire or fencing on line E,
F, Figure 9.
In the Drawings A represents the main frame standing upon four legs A¹. The
main wire B which is fed into the machine from a coil or reel passes directly
through the machine as indicated in Figures 6, 7, and 8, by first passing through an
opening or hole "a" in the projection b on the stand piece A", and under the
clamping arm b' on the lever B¹, which is pivoted at a¹ to one angle on the
projection b. The wire is then passed between the feed rolls C, C₁, upon the
shafts C, C, which turn in suitable bearings in the standards D, D, one on each
side of the machine, said standards D, D, being connected by a top plate D. The
peripheries of feed rolls C, C¹, are so made and arranged as not to come in contact
with the main wire B only when certain portions of their peripheries come opposite

page_text: to each other, videlicet, those portions marked d, d, in the Drawings, and which
portions project out beyond the other portions of the peripherier of said feed rolls
as fully indicated in the Drawings. The main wire then passes through a hole in
the end of a stationary bearing piece E, in which is arranged a spiral spring d¹, and
through which the wire passes forward, and thence through a hole in the centre of
the rotating and barb winding shaft E¹ which turns in bearings E", Ell, one end
projecting into the rear end of the stationary bearing piece E, and abutting against
the spiral spring das indicated in Figure 6. The wire then passes forward and
through the compressing jaws F, F¹, the latter jaw F¹ being provided with a
groove, into which the lower edge of the main wire B projects slightly while the
face of the upper jaw F has a plane surface. These jaws are made inclined upon
their outer edges to fit corresponding inclined grooves formed one in the top of the
stationary base piece G, and the other in the face of the barb compressing lever G¹,
which lever is pivoted or fulcrumed a e in the standard G₁, the rear end of
lever G¹ projecting forward and resting upon cam H, H, which is securely fastened
on shaft C, jaws F, F, may be held in place by keys or set screws 1, and by
making said jaws wedging shape upon their outer edges as shewn in Figure 6, by
adjusting them in or out, a greater or less space may be obtained between their
faces which will always remain parallel to each other. Shafts C₁, C, are geared
together by means of the cog gear H, H', consequently the relative motions of the
feed rolls C, C¹, will always be found in unison, and the action of compressing
lever G will always be at a given point in the rotation of said feed roller and cam H,
which moves with feed roll C¹.
From the foregoing description it will be seen that the main wire B will be fed
forward a given distance at cach rotation of the feed roller C, C1, the distance at
which said main wire will be fed being equal to the length of the projecting parts d, d,
upon the peripheries of said feed rolls, and in practice I prefer to make said pro-
jecting parts d, d, of steel, and have them slightly grooved to fit the main wire
properly. Shaft E' is provided with a bevil gear f, which merges into a bevil gear fl
on shaft turning in bearings 2, 2. Bevil gear f is not keyed to shaft E', but has
a slot, into which a spline on shaft E¹ fits; consequently while shaft E¹ is rotated
by means of the gear, f¹, it can move longitudinally as the barb wire is wound
upon the main wire, as will be hereafter explained. Upon the opposite end of
shaft C from gear H¹ is fastened a skeleton cam gear wheel I, and outside of that
upon the same shaft a cam wheel I, the latter operating the barb wire feeding
lever J, which is pivoted at 3, and whose action will be presently described.
It will be noticed that the cogs 4 on cam gear wheel I extend only a part way
around; consequently, as gear I¹¹ on shaft flis driven by the cogs 4, shaft fi
bevil gear f¹ and f are at rest, as well as shaft E' during about one-half of each
revolution of the feed rolls C and C, and it is during this time that the main wire
is fed forward the proper distance, and also the barb or cross wire is also fed forward
the desired length necessary to form the coils about the main wire and the barb on
one side of the same.
To prevent gear I from moving out of place after cogs 4 have been moved out of
mesh with its teeth, a locking lever is pivoted at 5, and is pressed down by a
spring 6; said lever g is provided with a hooked end 7, which extends under the
edge of the cam part 8 on wheel I, whereby when cogs 4 begin to take into teeth 9
on gear I the bevilled end 10 of cam 8 runs over the bent or hooked end 7 of
lever g, and raises the long arm g¹ thereof, thereby releasing the bent end 11 from
the teeth 9, thus leaving gear I free to move, but as soon as cogs 4 cease to act on
gear I the hooked end 7 is released from cam 8, and spring 6 instantly depresses
the long arm of the lever and locks gear I11, as shewn in Figures 4 and 5. The barb
or cross wire is fed from a roll or reel as follows:-The end of the wire is passed
between the jaws h and i, jaw l being held in a rigid finger k fastened to the end
of feed lever J, while jaw i is fastened to a finger on the moveable sleeve piece m
fitted to work back and forth on feed lever J, a spiral spring 12 being arranged

page_text: between the sleeve piece and an adjusting nut m¹ on said lever. Spring 12 tends
to force jaw i against jaw h, and keeps up close to it, only when jaw i is forced
back by the action of a moveable wedge n fitted to slide back and forth through
slots in both the sleeve piece m and in the end of the feed lever J. Wedge n, as
lever J is vibrated back and forth is forced alternately against the ends of the
adjusting screws o and p, which pass through suitable stands secured to the main frame.
The form of wedge n and the slot in the lever J ure shewn in full and dotted
lines, Figure 4. When the parts are in the position shewn in Figure 4 the head of
wedge n is acted upon by coming in contact with the point of screw o, and sleeve
piece m is forced back, thereby opening the jaws h and i, while when lever J moves
in the opposite direction the point of the wedge will come in contact with the point
of screw p, and the wedge will be driven in the opposite direction or out of the
slot, where spring 12 will instantly force sleeve piece m forward, and close the jaws.
The form of the inclined side of wedge n is such that the action of spring 12 will
cause the wedge to move very quickly after it has been driven most out by screw p.
The cross wire K to form the barbs K¹, K¹, is fed through between the jaws h and i,
thence through a hole g in the angular lever L hinged at L¹ to the main frame,
while its long arm L¹¹ has a rounded projection which drops into a corresponding
depression, in the circular flange 14 on the inside of the gear I¹¹ whenever said gear
is locked by lever g, as shewn in Figures 4 and 5. M is a standard, against the edge
of which the side of lever L works, so that when the projection 13 on lever L drops
into the depression on circular flange 14, as shewn in the Figures 4 and 5, the cross
wire which passes through the hole q will not come in contact or be bound against
standard M, but will be so bound wherever gear I¹¹ is moved so as to raise pro-
jection 13 upon the periphery of the said flange, which is on a line or nearly so with
the base of teeth 9 on gear I". The cross wire, after passing through hole q in
lever L, is run forward over an inclined arm M hinged at 15, and resting upon an
adjusting screw 16. Above this inclined arm M' is a spring arm 17, the rear end of
which is fastened to standard M, and the cross wire passes between the upper edge
of inclined arm M₁ and lower edge of spring arm 17; it is then run forward, and
passed above the main wire B and under a projecting finger 18 in the head N of
shaft E, and when in this position it will pass up between the cutters N¹, N¹¹, the
former being stationary, and the latter secured to a sliding head N operated by
the vertical arm of lever O, which is pivoted at 19 to a lug or projection.20 on the
under side of the machine. The rear end of lever O is bent up and extended forward,
and is provided with a pin 21, which fits into a groove in the side of a cam wheel O¹
fast upon shaft C11, as indicated in dotted lines, Figures 4, 5, and 6, and the form of
the groove in cam wheel O' is such as to give the necessary forward motion to
cutter N at the proper time for cutting off the cross wire after its end has been
wound around the main wire the desired number of times, and in practice I have
found that twice around the main wire and partly round the third time, us shewn
in Figures 7, 9, and 11, will generally be sufficient. In this instance inclined arm M
extends forward under and beyond the main wire B, and terminates with a curved
point 22. The object of this curved point or guide is to give the end of the cross
wire when first acted upon by finger 18 a back spiral motion as it is being wound
about the main wire to form the first coil thereon. In lieu however of this arrange-
ment a separate guide piece 22 may be employed, said guide piece being secured to
some permanent part of the frame of the machine.
The cutters N and N₁ are secured by means of set screws 23 and 24 respectively,
said set screws passing through plates 26 and 27 (see Figures 4 and 7). Cutter N¹
rests in a slot or recess formed in the top of stand P, while cutter N rests in
a slot or recess formed in the top of the moveable head N, which is fitted
to move back and forth upon the top of stand P¹ as lever O is operated, the
joint between sliding head N and the top of stand P¹ being hidden from view in
Figure 5 by lever J. Sliding head N is retained in the proper relative position
as it works back and forth upon the top of stand P¹ by suitable guides combined

page_text: with the lower side and the top of stand P¹, but as these guides are of ordinary
construction in all cases when it is desired to retain a moving part from lateral
motion when moving back and forth, no further description is here necessary. By
turning screw 16, which rises up from the main frame and supports inclined arm M³,
the outer end 22 of said arm can be raised or depressed as the case may be, thereby
elevating or lowering the cross wire at the point whore it passes up between the
cutters N' and N1, since said wire rests upon the upper edge of said arm just under
the cutters, whereby said wire can be fed to or supported so that the cutters will
cut off the wire at a greater or less angle 28. If desired, the upper edge of
arm M under the cutters or between the cutters and centre of shaft E' may be
formed with a slight groove or depression into which the lower edge of the cross
wire can rest, thereby retaining it more securely in position while its end is being
wound around the main wire. In this instance said inclined arm M¹ is bevilled off
on its edge next to cutter N¹, so that said wire rests or is held in place between
the end of stationary cutter N¹ and flange or bevilled edge 29 of arm M'.
If it is desired to make a short cut or bevil 28 for the barbs K¹, K¹, then the
outer end of inclined arm M' is raised, but if it is desired to increase the length of
the bevil or cut 28 then the outer end of said arm is lowered.
A standard Q is secured to the side of the block or anvil piece G which supports
the lower die F, and to the upper end of said standard Q is hinged at 30 one end of
lever Q1; the other end of said lever, which is bent down and provided with a foot
adapted to rest and press upon the cross or barb wire K between the cutters and
the main wire B, is operated by a pin 31 which projects from the side of lever G¹
and passes through a slot 32 in said lever Q1, and from which arrangement it will be
seen that the foot 33 of lever Q will be forced down upon said. cross wire when the
head of lever G¹ is depressed, and vice versa.
Shaft E' is provided with a flange or hub S, while sliding head N¹¹ is provided
with a projecting pin t, whereby when said sliding head is moved forward to cut off
the cross wire K, pin t will strike against hub S and move said shaft E¹ forward to
its proper position to pass its finger over the end of cross wire K should spring d¹
at any time fail to force said shaft forward when the main wire B is fed forward
after the cross wire has been coiled about it, as shewn in Figure 7.
Lever B¹ is forced down by means of cam B, shewn in dotted lines, Figures 4, 5,
and 6, whereby said lever is caused to press by means of its lug or finger b' upon
the main wire B with increased force at the time when the cross wire is being fed
over the main wire, and also when finger 18 on head N of shaft E¹ commences
to coil the barb wire about the main wire, but said lever B¹ is released from the
pressure of said cam before the feed rolls C, C', commence again to feed forward the
main wire.
In case it is desired to coil the barb wire around two or more main wires, then a
supporting lever T is hinged to a standard T¹ upon the main frame with its rear
end provided with a slot to receive a projecting pin u in the head of lever G¹, so
that when said head is depressed the end T¹ of lever T will be elevated to support
said main wires and thereby prevent one from being twisted around the other when
the barb wire is coiled around them by finger 18; when however a single main
wire is used lever T may be dispensed with. If preferred the faces of both the
dies F and F may be made smooth, or they may be grooved or corrugated, as found
most effective in practice. By arranging the foot Qu of lever Q so that it will be
depressed by means of lever G¹ to bear firmly upon the cross or barb wire between
the cutters and the main wire, as indicated in Figure 7, which Figure represents
upon an enlarged scale a plan view of a portion of the coiling and cutting-off
mechanism. The cross wire can be wound far more tightly and compactly about
the main wire than it could be without said lever.
As the barbed wire is delivered from the machine it can be wound upon a reel
by power or otherwise in a convenient form for storage or train portation. Then
again as the barbed ends project in the same horizontal plane or nearly so, and are

page_text: always upon the same side of the main wire for its whole length, the barbed fence
wire can be wound upon and unwound readily from the reel without liability of
the barbed ends of one strand catching into the other strands, since each set of
barbed ends will be separated from those under them by the diameter of the main
wire added to that of the barb wire.
As the barbed wire leaves the machine it may be given one or more twists, when
two or more main wires are used before it is wound upon the reel, the twists being
made between the various sets of barbs or groups. The barbed ends can be made
to stand in the same relative position as they do when the wires are not twisted,
and consequently the barbed wire can be wound up and unwound as readily as if
not twisted. When a single main wire is used I prefer that it should be No. 9 and
the cross or barb wire No. 12. Of course the size of both wires may be varied to
suit the particular use to which the fence wire is to be applied.
It will be understood that the parts of the machine may be modified and made
somewhat differently than what is shown in the Drawings without departing from
the principle of the Invention, one good way of applying the same to practical use
being shown and described herein.
Referring to the feed arm J, the outer end upon which the spiral spring 12 and
nut m are placed, is made separate from the other end, the former part being
slipped into a socket in the latter and there held by a set screw v, and by moving the
said detachable part out or in the feed can be increased or shortened, as occasion
may require. The grip of jaw i upon the cross wire can be regulated by nut m¹,
since by screwing the nut out towards the spring its pressure will be greater upon
the jaw, and vice versa.
The feed jaws may also be arranged to move back and forth in a direct line when
a long feed is required, in which case the feed lever could have a lug fitting into a
slot in the sliding jaw frame or vice versa. Still again the feed lever may be
provided with a shifting fulcrum for adjusting the throw of the feed jaws. Screw p
is so arranged that it will force wedge n back and allow spring 12 to close the jaws
upon the barb wire, just before lever J reaches its utinost outer throw, thereby
slightly withdrawing the wire from the cutters N', N₁, and by which operation
cutter N does not drag in contact with the wire when it is withdrawn, con-
sequently its edge remaines unimpaired for a long time, and it therefore makes a
much cleaner and sharper cut than it would if the barb wire was not withdrawn
slightly after each cut and before the cutter N₁ was withdrawn.
A practical test has shown that unless the barb wire is retracted as above stated,
it soon wears off the lower corner or edge of cutter N¹¹, consequently this is a very
important feature of the Invention, since it ensures such a perfect cut that the
pointed ends of the barbs are almost as effective as needle points, which is very
desirable in a barbed fence wire. The ends of the cutters N₁, N", may be made to
incline down slightly towards the main wire, whereby there will be less liability of
the cross wire slipping from the action of the cutters. Then again the feeding
mechanism may be made to have the barbs stand at a greater or less distance apart
upon the main wire.
OPERATION.
The operation of the machine may be briefly stated or summed up thus:-The
machine is turned until the portions d, d, of the feed rolls C, C¹, almost come
together upon the main wire when the latter is fed or pushed along until its end is
a little past the cutters, thus the cross or barb wire is fed in until the end reaches to
about one half of an inch of the main wire; then the machine is set in operation by
power applied to shaft C in any well known manner, and the feed rolls C, C¹, feed
the main wire B along some five inches, making about one quarter of a revolution
in the operation. The main wire is now at rest, and about an eighth of a
revolution more carries the barb wire by means of the action of feed lever J, and
its jaws h and i over the main wire sufficiently far to form the coil U and one barb

page_text: end K', the main wire being held firinly at rest by the closing of the dies F, F¹, and
the action of cam B" on lever B¹ as before explained.
As the machine continues in operation the end 10 of cam 8 forces down the end 7
of lever-g, and releases gear 111, at the same time cogs 4 on wheel I have reached the
cogs 9 of gear I", and set the latter in operation, thereby communicating a rotatory
motion to shaft E' and tinger 18 on head N, whereby finger 18 is forced down upon
the barb wire bending the end which projects over the main wire down and around
the latter, until the barb wire comes in contact with the curved guide 22, which
gives to it a back spiral direction around the main wire, so that when it comes up on
the inner side it will not strike against the barb wire between the cutters and the
main wire, but will be carried between it and cutter N", shaft E¹ receding as the
barbed wire is wound around the main wire.
Figure 7 represents the end of the barbed wire wound around the main wire
ready to be cut off by the cutter N at the next forward motion. As soon as
finger 18 renches to the point shown in Figure 7 the coil U being completed, the
gear I is locked again, and the main wire and cross wires are released from the
action of the levers B₁ and L respectively, when the cutter N being moved
forward it cuts off the cross wire a sufficient distance from the coil to leave the the
barb K on that side. By the time the cutter N" commences to cut the wire K
the feed rolls have commenced to feed forward the main wire B, at about the same
speed at which the cutter moves, consequently the main wire and coil U and its
barbs K¹, K', move forward together until a sufficient length of wire B has fed
forward to receive another coil, which is formed as before explained. The jaws or
dies F, F, are so arranged that when the main wire stops after a coil has been
formed, the newly formed coil will be between said jaws or dies, whereby when the
head of the compressing lever G¹ descends, the coil will be clamped between the
dies F, F, which hold the same quite firmly until just before the cutter N¹ moves
forward and cuts off the barb wire, when the small projection X on can H causes
lever G to force down its die F with great power upon the coil U, so much so as
to flatten the sides of the coils, as shown in Figures 9, 10, and 11, of the Drawings.
The power is also so great as to force the coils into the main wire, as indicated in
Figure 11. By this compression the coils are firmly secured to they main wire, so
that it is with great difficulty that they can be turned upon the main wire except
with a strong wrench lever.
As before explained when feed lever J moves back to take a new hold upon the
cross wire K, it at the last of its motion withdraws the wire, thus preventing the
cutter N from dragging upon it when moving back after having cut off the wire.
By adjusting screw p in or out the wire can be withdrawn more or less as desired.
It will be seen that the hollow shaft E' stops at a point just after the finger 18 has
moved over the centre of the shaft, consequently when the end of the cross or barb
wire is fed forward above the main wire to form the next barb, it passes under the
finger and is in the proper position to be acted upon by the finger when shaft E' is
put into motion.
It will be observed that by this Invention barbed fence wire or fencing can be
produced in a continuous and rapid manner, while all the coils and barbed ends are
of a uniform shape and size.
