Improvements in Machines for Forming Wire Fencing.
I, HENRY WATERS HARTMAN, of Beaver Falls, Beaver County Pennsylvania,
United States of America, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines for forming wire bands or ribbons for use
particularly in the construction of fences; and wherein the arrangement of the
automatic mechanism is designed for producing a band consisting of two parallel
line wires and a third intermediate wire so formed and intertwisted as to render the
band strong, stiff, and not liable to buckle, and comparatively lighter and of less
cost than any similar band of which I have knowledge.
My said invention comprises in combination, devices whereby a single inter-
meliate or filling wire is shifted alternately, diagonally and in successive coils from
one to the other of the parallel line wires at regular spaces and in which a pair of
spindles for said line wires are adapted to be alternately rotated each in a constant
direction opposite to the other, in the operation of intertwisting the said wires ;
and in which the said intertwisting is made so that the intermediate or filling wire
is caused to embrace and be intercoiled with similar coils in the parallel line wires
from opposite sides of the band at each alternate point of twisting, that is to say,
the filling or intermediate wire is caused to pass over at one side of the band and be
intertwisted with one of said line wires, and then pass diagonally under it to the
opposite side of the other of said line wires and be intertwisted with it in successive
engaging coils so as to brace and stiffen the formed band against its tendency to
buckle or twist. The provision for effecting the intertwisting or engaging of the
wires at the successive coils as above stated, is an essential feature of invention and
is effected by the delivery of the wires through passages arranged eccentrically in
the journals of their rotating carriers, in connection with a shuttle shifted alternately
in co-operating relation with a pair of spindles adapted to be alternately rotated
each in a constant direction opposite to the other, as will be hereinafter
explained.
For the production of such a band or ribbon I have arranged a machine of
comparatively simple construction, which after commencing the operation and
engaging the end of the formed band or ribbon to a matrix wheel device which acts
to pull the band requires no attention until the intermediate or filling wire carried
by the twisting shuttle, is exhausted from its spool, when a filled spool is
substituted its wire connected with the end of the filling wire in the band and the
machine again put in motion all the wires being drawn forward by the continuous
rotation of the matrix wheel in the operation.
My invention consists of certain parts and combinations of parts the several
features of which will be hereinafter described.
In carrying my invention into practice upon an iron bed suitably supported, is
erected the operating mechanism which comprises the organized machine. Upon
this bed at one side and standing longitudinally of the machine is mounted in
suitable standards a main shaft having at one end a pinion and at its other end a
bevel wheel and between these gears, cams of identical form, are secured in
identical positions so as to act simultaneously. Between one of these cams and the
bevel wheel a segmentally toothed large wheel is secured upon this shaft, and has a
face flange around the non-toothed part of its circumference. Upon this bed at the
other side thereof, is mounted in suitable standards a second shaft in parallel relation
with the main shaft and having cams of identical form in identical positions and in:

page_text: co-incident relation to the cams on the main shaft and for simultaneous action, and
these cams form the shuttle throwing device. On this second shaft is secured a
segmentally toothed large wheel of identical construction to that on the main shaft
and these two large wheels are formed with gear teeth for one-fourth of their
circumference, and the remaining three-fourths of such circumference, is an
broken surface in a line co-incident with the base of the teeth and bounding this
unbroken surface is a face flange the circumference of which is co-incident with the
crown of the teeth, for a purpose hereinafter mentioned. A bevel gear is mounted
on the end of this shaft in co-incident relation to the bevel gear on the main shaft
and these two bevel gear are engaged by like bevel gear on a cross shaft mounted
in bearings at the rear of the table, whereby the main and second shafts are caused
to rotate continuously in unison and in opposite directions toward each other for
the purpose hereinafter stated. Within the space between the parallel shafts are
fixed two head blocks each in co-incident relation to each pair of cams and within
and between these head blocks are fitted, in parallel relation, two spindles standing
longitudinally and centrally between the cam shafts for carrying and guiding the
parallel band wires. The receiving ends of these spindles are mounted in a pillar
block and the wires are supplied to the bores thereof from spools mounted in any
convenient way at the rear of the bed and it will be understood that the distance
between the axis bores of these spindles is just equal to the width of the band to be
formed and that said spindles are adapted to be alternately rotated each in a
constant direction opposite to the other.
Each head block has a cap or housing open on its under side joining the head
block and within this opening is fitted a shuttle block so as to have a lateral sliding
movement within said caps, a distance just equal to the width of the band to be
formed, and the ends of this opening form stops to determine the stroke or throw of
the shuttle-block for a purpose hereinafter stated.
Each spindle is preferably bow shape between its journal and its journals are of
semi-circular form in cross section and are fitted in the semi-circular cavities in the
upper face of the head block so that in the depending or normal positions of the
bowed spindles, the flat sides of their journals will be flush with the upper faces of
the head-blocks. The journal of each spindle has a bore eccentrically placed which
leads to and intersects a groove around the outer side of the bowed part to hold and
guide the line wires to the eccentric points at which the filling wire is twisted at
the outer side of the front delivery shuttle-block and for this purpose the said
spindles terminate outside the shuttle blocks, while the bowed parts of the spindles
stand between them. The under side of each shuttle block has a semi-circular
cavity which forms the bearings for the journals of an open frame within which is
mounted a spool which carries the filling wire and this journalled frome and spool
forms a rotating twisting shuttle which delivers the filling wire through a bore in
the front journal eccentrically with and just over the wire of the front delivery
spindle journal where the twisting of the two wire strands is effected by the eccentric
relation of both wires to their delivery journals.
It is to permit the arrangement of the filling wire spool, within the open frame
that I make the spindles bow shaped, so that the spool frame can be shifted side
wise over the spindles to shift the filling wire alternately in co-incident relation to
the line wires and bring the filling wire so as to enter the eccentric journal bore
of the open frame.
The shuttle blocks are reciprocated simultaneously back and forth within their
housings by the cams through the intervention of the push pins fitted to slide
within the opposite ends of said housings in abutting relation to the opposite ends
of the sliding shuttle blocks, and to the said cams, the push pins having anti-friction
rolls to receive the action of said cams. The throw of these cams is just equal to
the distance between the centres of the spindle, and the throw of the shuttle blocks
is thereby made to bring the journal of the twisting shuttle in alternate co-incident
relation to the journals of the spindles, and for this purpose the journals of the
spindles are made of semicircular form in cross section so that their flat faces will

page_text: be coincident with the undersides of the sliding shuttle blocks, which, in the move-
ment of the latter, permits the journals of the twisting shuttle to be moved over
and into co-incident relation to the journals of the spindles, so that the two half-
parts of these journals match with their flat faces joining, forming a single journal
bearing to permit the bowed spindle to be revolved together and with the twisting
shuttle as an entirety, for the purpose stated.
In this operation each spindle is caused to rotate in a constant direction opposite
to the other in alternate order so that the device as an entirety, has an alternate
rotation each one being in a constant direction opposite to the other, to intertwist
one diagonal filling wire in successive engaging coils with two straight line wires,
so that the said filling wire will pass from one side of the band at one line wire to
the opposite side of the band at the other line wire. The spool for the filling wire
is mounted in the shuttle frame by a removable bolt.
In the wire receiving end of each bowed spindle, is secured a pinion which
engages the teeth of the segmentally toothed wheels, and these pinions have each a
face flange the circumference of which is flush with the crown of its teeth and is in
co-incident relation to and revolves on the flange of its co-acting segmentally
toothed wheel. Each of these pinion flanges has its circumference interrupted or
cut away by an are co-incident to the radius of the flange of the segmentally toothed
wheel for the purpose of allowing the flange of the latter wheel to enter the
segmental cut in the flange of the pinion and thus arrest its rotation and hold it
from turning so long as the said wheel flange is in engagement with the said cut in
the pinion flange.
The effect of this flange engagement is to cause the pinions to make intermittent
revolutions; while the motion of the segmentally toothed wheels is continuous,
because as this wheel is toothed over a portion of its circumference only and flanged
only over the remainder of its circumference, it therefore rotates its co-acting
pinion over the toothed circumference only an 1 locks the said pinion from rotation
over the flanged circumference. This rotation and duration of rotation to rest may
be changed by changing the relative sizes of the wheels and pinions or by changing
the relative proportions of toothed and flanged circumference.
Immediately in front of the delivery ends of the spindles, is mounted an idle
cylinder so that its upper side is preferably on a plane with the line wires emerging
from the said spindles, and near each end the said cylinder has a circumferential
row of radial pins outside of which the parallel wires are led and by which the said
wires are supported and retained in parallel relation at the proper distance apart,
while they are being intertwisted with the filling wire.
This intertwisting of the wires in successive coils is effected by the alternate
shifting of the shuttle frame from its co-incident relation with one spindle to the
other so as to carry the filling wire alternately from one to the other across the
space between the parallel wires at regular distances so that the filling strands will
stand in diagonal relation to each other; while the intertwisting of the wires is
effected by the rotation of the spindle and the shuttle frame which are rotated
together as an entirety in alternate order, each entire device in a constant direction
opposite to the other during a complete revolution of the pinion operating such
spindle and the continuous forward drawing of the formed band by the eccentric
relation of the wires in their respective delivery journals. The means for effecting
this forward drawing of the band and for holding and guiding it from the spindles
will now be described.
Immediately in front of the idle cylinder is mounted a second cylinder or wheel
having near each end a circumferential row of radial blocks disposed so as to stand
within and between the parallel and filling wire so as to form on the surface of the
cylinder a sort of depressed matrix or pattern of the band and by which the latter
is drawn forward and by which it is laid and retained in shape and prevented from
twisting and buckling during its passage from the first described pin-cylinder and
for delivering it smoothly to a take up reel. This matrix wheel has a positive
continuous motion given to it by a bevel gear engaging with a similar gear on a

page_text: short shaft in line with and below the cam shaft and which has a gear wheel on its
inner end which engages with the pinion of the cam-shaft so that motion being
given to the said cam shaft by a belt from the pulley thereon will operate the cam
shafts, the sliding shuttle blocks the rotary twisting shuttle the spindles and the
matrix wheel. In this operation it will be understood that the relative speed of
the twisting devices to that of the matrix wheel, is determined by the relative sizes
of the gear wheel and its engaging pinion on the driven cam-shaft.
A reeling device is arranged beneath the bed, the reel whereof is mounted on a
short shaft and driven by a hand pulley thereon from the pulley on the shaft of the
matrix cylinder, the formed bend for this purpose being connected to the reel and
reeled thereon as it is formed. When the shuttle blocks of both head blocks are
at the end of their stroke or throws, and the shuttle frame mounted therein and
carrying the filling wire is co-incident with the spindle the wires having been
previously carried through the spindle journals and through the front journal of
the shuttle frame, and the machine started, the shuttle and spindle will revolve
together in an outward direction and their individual wire will be intertwisted until
the cogs of the wheel cease to mesh with those of the pinion at which point the
flanges of these wheels come in contact and the spindle will be held idle while the
wheel will continue to revolve. At this point the continuous rotation of the cam
shafts will by the action of their cams move the shuttle blocks to the other end
of their throw and thereby bring the journals of the shuttle frame co-incident with
the journals of the other spindle and they will be rotated together in an opposite
direction and their individual wires will be intertwisted until the cogs of the
segmentally toothed wheel cease to mesh with those of the pinion at which point
the flanges of these wheels come in contact and engagement and the spindle will be
held idle while the said wheel will continue to revolve and this operation goes on
continuously producing the band just in front of the front head block and as the
said baud is drawn therefrom over and upon the cylinder during which the shuttle
shifts back and forth from one spindle to the other and each spindle is alternately
rotated together with the shuttle in a direction constantly outward and therefore in
opposite directions to each other.
It is important now to notice that in a certain position of the intertwisting device
the shuttle wire will be twisted over the upper side of the spindle wire with a
number of twists produced by one revolution of the pinion and leaving this wire on
its under side passes over diagonally to the other spindle wire by the lateral shifting
the shuttle blocks and the filling wire shuttle which they carry, and be twisted over
the upper side of the said wire with a number of twists produced by one revolution
of the pinion, and leaving this wire on its under side is passed diagonally to the
first mentioned spindle wire and twisted over its upper side the diagonal strands
being formed by the forward movement of the band as it is formed and the twisting
of said wire being from alternate sides of the band at each alternate point of
twisting, thus producing a band of three wire strands, in which the filling wire is
made to stiffen brace and preserve the alignment of the band. This operation is
effected at the delivery ends of the journals of the spindles and of the shuttle frame,
and the band is drawn forward by hand until a sufficient length is formed to be
engaged with the radial blocks of the cylinder and to be fastened to the reel, when
the machine requires no further attention until the wire in the shuttle frame is
exhausted and the empty spool is then replaced by a filled one its wire connected,
and the machine again put in motion.
The proper tension of the filling wire is maintained by a spring or by other
suitable means.
It is important also to notice that it is necessary that the relation of the toothed
portions of the segmentally flanged wheels shall be such that they shall cause no
more than one complete revolution of the spindles, they shall return to that position
from which they started for the next stroke of the shuttle block which reverses the
laterally shifting action of its frame.
It is also important to notice that the drawing of the wires by the continuous

page_text: action of the matrix wheel prevents any slack in the wires at the point of twisting,
because the wires are drawn from their respective spools toward and from such
points and being connected to each other at their points of engagement with said
wheel there can be no unequal drawing of them.
It will of course be understood that the speed of the drawing matrix wheel,
the take up reel, and the operation of the shuttle and twisting devices are in
unison, and that the matrix wheel serves to support the formed band in horizontal
and longitudinal alignment with the band forming devices and to deliver it at a
fixed speed in smooth condition to the winding reel. For this purpose the surface
blocks of the matrix wheel are disposed in such a manner as to stand within the
diagonal strands of the filling wire and between the line wires, to lay and even
the band wires and to support them under the drawing action of the matrix wheel
in proper aligument with the wire carrying spindles.
It will also be understood that the sliding boxes may be formed with or inde-
pendently of the cam abutting pins, and the said boxes may be retained in position
on the head blocks by any suitable means which will limit their reciprocating
movement for the purpose stated.
An important feature in the construction of my machine is the provision of a
pair of spindles for the two line-wires, each having a wire delivery passage at one
side of the axis of rotation, each rotated alternately in a constant direction opposite
to the other, and arranged in fixed relation on the frame, and a shuttle for the
filling wire having a wire delivery passage at one side of its axis of rotation and
having an alternate lateral movement for coincident relation with and rotated by
and with each separate spindle, so that in each position the said coincident parts as
an entirety has a constant direction opposite to the other when the said shuttle is
shifted thereto. In the operation of this coiling, and intertwisting device it will be
observed that spindles are geared each to a separate mutilated gear for separate
and independent rotation in directions one constantly opposite to the other, and
that the shuttle is mounted for separate and independent lateral movement and
for rotation by and with each spindle, whereby the filling wire is coiled in alter-
nately opposite directions with each side of the band over the line wires and both
the filling and the line wires are intertwisted with each other in successive coils
along the straight line wire in the way described to make a narrow band of ribbon
braced and stiffened.

I, HENRY WATERS HARTMAN, of Beaver Falls, Beaver County, Pennsylvania,
United States of America, Manufacturer, do hereby declare the nature of this
invention and in what manuer the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to machines for forming wire bands or ribbons for use
particularly in the construction of fences; and wherein the arrangement of the
automatic mechanism is designed for producing a band consisting of two parallel
line wires and a third intermediate wire so formed and intertwined as to render the
band strong, stiff, and not liable to buckle, and comparatively lighter and of less
cost than any similar band of which 1 have knowledge.
My said invention comprises in combination devices whereby a single intermediate
or filling wire is shifted alternately, diagonally and in successive coils from one to
the other of the parallel line wires at regular spaces and in which a pair of spindles
for said line wires are adapted to be alternately rotated each in a constant direction

page_text: opposite to the other, in the operation of intertwisting the said wires and in which
the said intertwisting is made so that the intermediate or filling wire is caused to
embrace and be intercoiled with similar coils in the parallel line wires from opposite
sides of the band at each alternate point of twisting, that is to say, the filling or
intermediate wire is caused to pass over at one side of the band and be intertwisted
with one of said line wires, and then pass diagonally under it to the opposite side of
the other of said line wires and be intertwisted with it in successive engaging coils
so as to brace and stiffen the formed band against its tendency to buckle or twist.
The provision for effecting the intertwisting or engaging of the wires at the
successive coils as above stated, is an essential feature of invention and is effected
by the delivery of the wires through passages arranged eccentrically in the journals
of their rotating carriers, in connection with a shuttle shifted alternately in
co-operating relation with a pair of spindles adapted to be alternately rotated each
in a constant direction opposite to the other, as will be hereinafter explained.
For the production of such a band or ribbon I have arranged a machine of
comparatively simple construction, which after commencing the operation and
engaging the end of the formed band or ribbon to a matrix wheel device which acts
to pull the band requires no attention until the intermediate or filling wire carried
by the twisting shuttle, is exhausted from its spool, when a filled spool is substituted,
its wire connected with the end of the filling wire in the band and the machine
again put in motion all the wires being drawn forward by the continuous rotation of
the matrix wheel in the operation.
My invention consists of certain parts and combinations of parts the several
features of which will be hereinafter described.

the parallel wires to the other; and
Figure 12 shows a portion of a band produced by my machine.
In carrying my invention into practice upon an iron bed 1 suitably supported is
erected the operating mechanism which comprises the combined machine. Upon
this bed at one side and placed longitudinally on the machine is mounted in suitable
standards 3, a main shaft 2 having at one end a pinion 4, and at its other end a
bevel wheel 5 and between these gears, cams 6 and 7 of identical form are secured
in identical positions so as to act simultaneously. Between one of these cams and
the bevel wheel 5, a segmentally toothed large wheel 8 is secured upon this shaft,
and has a face flange around the non-toothed part of its circumference. Upon this
bed at the other side thereof, is mounted in suitable standards 10, a second shaft 11

page_text: in parallel relation with the main shaft 2 and having cams 12 and 13 of identical
form in identical positions and in coincident relation to the cams 6 and 7 on the
main shaft and for simultaneous action therewith and these cams form the shuttle
throwing device.. On this second shaft 11 is secured a segmentally toothed large
wheel 8 of identical construction to that on the main shaft 2 and these two large
wheels are formed with gear teeth 15 for one-fourth of their circumference, and the
remaining three-fourths of such circumference, is an unbroken surface 16 in a line
co-incident with the base of the teeth, and bounding this unbroken surface is a face
flange 17 the circumference of which is co-incident with the crown of the teeth, for
a purpose hereinafter mentioned. A bevel gear 18 is mounted on the end of this
shaft 11 in co-incident relation to the bevel gear 5 on the main shaft 2, and these
two bevel gears are engaged by like bevel gear 19, 20 on a cross shaft 21 mounted
in bearings at the rear of the table, whereby the main and second shafts 2 and 11
are caused to rotate continuously in unison, and in opposite directions toward each
other for the purpose hereinafter stated. Within the space between the parallel
shafts, are fixed two head blocks 22 and 23 each in co-incident relation to each pair
of cams, and within and between these head blocks, are fitted in parallel relation,
two spindles 24 and 25 standing longitudinally and centrally between the cam shafts
for carrying and guiding the parallel band wires. The receiving ends of these
spindles are mounted in a pillar block a and the wires bb¹ are supplied to the bores
thereof from spools not shown mounted in any convenient way at the rear of
the bed; and it will be understood that the distance between the axis-bores of
these spindles is just equal to the width of the band to be formed and that said
spindles are adapted to be alternately rotated each in a constant direction opposite
to the other.
Each head block has a cap or housing 26 open on its under side joining the head-
block and within this opening is fitted a shuttle block 27 so as to have a lateral
sliding movement within said caps, a distance just equal to the width of the band to
be formed, and the ends of this opening form stops to determine the stroke or throw
of the shuttle-block for a purpose hereinafter stated.
Each spindle is preferably bow shaped between its journals and the said journals
are of semi-circular form in cross section (Figures 2 and 7) and are fitted in the
semi-circular cavities in the upper face of the head block (Figure 2) so that in
the hanging or normal positions of the bowed spindles, the flat sides c of their
journals will be flush with the upper faces of the head-blocks, as seen in Figure 2.
The journal of each spindle has a bore 28 eccentrically placed which leads to and
intersects a groove 29 around the outer side of the bowed part to hold and guide
the line wires to the eccentric points at which the filling wire is twisted at the
outer side of the front delivery shuttle-block 27 and for this purpose the said spindles
terminate outside the shuttle blocks, while the bowed parts of the spindles stand
between them, as seen in Figures 1 and 6. The under side of each shuttle block
has a semi-circular cavity which forms the bearings for the journals 30, 30 of an
open frame 31 within which is mounted a spool 32 which carries the filling wire 33
and this journalled frame and spool forms a rotating twisting shuttle which
delivers the filling wire 33 through a bore 34 in the front journal eccentrically
with and just over the wire of the front delivery spindle journal where the twisting
of the two wire strands is effected by the eccentric relation of both wires to their
delivery journals.
It is to permit the arrangement of the filling wire spool, within the open frame 31
that I make the spindles bow shaped, so that the spool frame can be shifted
sidewise over the spindles to shift the filling wire alternately in co-incident
relation to the line wires; and bring the filling wire so as to enter the eccentric
journal bore of the open frame (as shown in Figure 1).
The shuttle blocks 27 are reciprocated simultaneously back and forth within.
their housings 26 by the cams through the intervention of the push pins 35-35
fitted to slide within the opposite ends of said housings and facing the opposite.
ends of the sliding shuttle box 27, and the said cams, the push pins having

page_text: anti-friction rolls 36 to receive the action of said cams. The throw of these cams
is just equal to the distance between the centres of the spindles and the throw of
the shuttle blocks is thereby made to bring the journal 30 of the twisting
shuttle 31 in alternate co-incident relation to the journals 28 of the spindles, and
for this purpose the journals of the spindles are made of semi-circular form in
cross section so that their flat faces d d will be co-incident with the undersides of
the sliding shuttle blocks, which, in the movement of the latter, permits the
journals 30 of the twisting shuttle to be moved over and into coincident relation
to the journals of the spindles, so that the two half parts of these journals match
with their flat faces c and d joining, forming a single journal bearing to permit
the bowed spindle to be revolved together and with the twisting shuttle as an
entirety, for the purpose stated.
In this operation each spindle is caused to rotate in a constant direction opposite
to the other in alternate order, so that the device as an entirety, has an alternate
rotation, each one being in a constant direction opposite to the other, to intertwist
one diagonal filling wire in successive engaging coils with two straight line wires,
so that the said filling wire will pass from one side of the band to one line wire and
from the opposite side of the band to the other line wire. The spool for the filling
wire is mounted in the shuttle frame by a removable bolt.
In the wire receiving end of each bowed spindle, is secured a pinion 37 which
engages the teeth of the segmentally toothed wheels, and these pinions have each
a face flange 38, the circumference of which is flush with the crown of its teeth,
ard is in co-incident relation to and revolves on the flange 17 of its co-acting
segmentally toothed wheel. Each of these pinion flanges has its circumference
interrupted or cut away by an ar: 39 co-incident to the radius of the flange of the
segmentally toothed wheel for the purpose of allowing the flange 17 of the latter
wheel to enter the segmental cut 39 in the flange of the pinion 37 and thus arrest
its rotation and hold it from turning so long as the said wheel flange 17 is in
engagement with the said cut in the pinion flange see Figures 10 and 11.
The effect of this flange engagement is to cause the pinions to make intermittent
revolutions; while the motion of the segmentally toothed wheels is continuous,
because as this wheel is toothed over a portion of its circumference only and
flanged only over the remainder of its circumference, it therefore rotates its
co-acting pinion over the toothed circumference 15 only and locks the said pinion
from rotation over the flanged circumference. This rotation and duration of
rotation to rest may be changed by changing the relative sizes of the wheels and
pinions; or by changing the relative proportions of toothed and flanged
circumference.
Immediately in front of the delivery ends of the spindles, is mounted an idle
cylinder 40 so that its upper side is preferably on a plane with the line wires br
emerging from the said spindles, and near each end the said cylinder has a
circumferential row of radial pins 41 outside of which the parallel wires are led
and by which the said wires are supported and retained in parallel relation at the
proper distance apart, while they are being intertwisted with the filling wire.
This intertwisting of the wires in successive coils is effected by the alternate
shifting of the shuttle frame 31 from its co-incident relation with one spindle to
the other so as to carry the filling wire 33 alternately from one to the other across
the
space between the parallel wires at regular distances so that the filling strands
will stand in diagonal relation to each other; while the intertwisting of the wires
is effected by the rotation of the spindle and the shuttle frame which are rotated
together as an entirety in alternate order, each entire device in a constant direction
opposite to the other during a complete revolution of the pinion operating such
spindle and the continuous forward drawing of the formed band by the eccentric
relation of the wires in their respective delivery journals. The means for effecting
this forward drawing of the band and for holding and guiding it from the spindles
will now be described.
Immediately in front of the idle cylinder 40 is mounted a second cylinder or

page_text: wheel 42 having near each end a circumferential row of radial blocks 43 disposed
so as to stand within and between the parallel and filling wires so as to form on
the surface of the cylinder a sort of depressed matrix or pattern of the band and
by which the latter is drawn forward and by which it is laid and retained in shape
and prevented from twisting and buckling during its passage from the first
described pin-cylinder and for delivering it smoothly to a. take up reel. This
matrix wheel has a positive continuous motion given to it by a bevel gear 44
engaging with a similar gear 45, on a short shaft in line with and below the cam
shaft 2 and which has a gear wheel 46 on its inner end which engages with the
pinion 4 of the cam-shaft 2 so that motion being given to the said cam-shaft hy a
belt from the pulley 47 thereon will operate the cam shafts, the sliding shuttle
In this
blocks, the rotary twisting shuttle, the spindles, and the matrix wheel.
operation it will be understood that the relative speed of the twisting devices to
that of the matrix wheel, is determined by the relative sizes of the gear wheel 46
and its engaging pinion 4 on the driven cam-shaft.
A reeling device is arranged beneath the bed, the reel 48 whereof is mounted
on a short shaft and driven by a hand pulley 50 thereon from the pulley 49 on
the shaft of the matrix cylinder, the formed band for this purpose being connected
to the reel and reeled thereon as it is formed.
Referring to Figure 2 it will be seen that when the shuttle blocks 27 of both
head blocks are at the end of, their stroke or throws, and the shuttle frame
mounted therein and carrying the filling wire 33 co-incident with, the spindle 24,
the wires having been previously carried through the spindle journals and through
the front journal of the shuttle frame, and the machine started, the shuttle and
spindle will revolve together in an outward direction and their individual wires bb
and 33 will be intertwisted until the cogs 15 of the wheel 8' cease to mesh with
those of the pinion 37, at which point the flanges of these wheels come in contact
and the spindle 24 will be held idle while. the wheel 8¹ will continue to revolve.
At this point the continuous rotation of the cam shafts will by the action of their
cams move the shuttle blocks to the other end of their throw and thereby bring
the journals of the shuttle frame co-incident with the journals of the other spindle
shown and they will be rotated together in an opposite direction, and their
individual wires will be intertwisted until the cogs 15 of the segmentally toothed
wheel 8¹ cease to mesh with those of the pinion 37 at which point the flanges of
these wheels come in contact and engagement and the spindle 25 will be held idle
while the said wheel 8' will continue to revolve, and this operation goes on
continuously, producing the band just in front of the front head block and as the
said band is drawn therefrom over and upon the cylinder 40, during which the
shuttle shifts back and forth from one spindle to the other and each spindle is
alternately rotated together with the shuttle in a direction constantly outwards
and therefore in opposite directions to each other.
It is important now to notice that in a certain position of the intertwisting device
as in Figure 2, the shuttle wire 33 will be twisted over the upper side of the spindle
wire bat e with a number of twists produced by one revolution of the pinion 37,
as seen at in Figure 12, and leaving this wire on its under side at g passes over..
diagonally to the other spindle wire 6 by the lateral shifting the shuttle blocks and
the filling wire shuttle which they carry and be twisted over the upper side at h of
the said wire b with a number of twists f¹ produced by one revolution of the
pinion 37, and leaving this wire b¹ on its under side is passed diagonally to the first
mentioned spindle wire band twisted over its upper side, the diagonal stands being
formed by the forward movement of the band as it is formed and the twisting of
said wire being from alternate sides of the band at each alternate point of twisting,
thus producing a band of three wire strands, in which the filling wire is made to
stiffen, brace, and preserve the alignment of the band. This operation is effected
at the delivery ends of the journals of the spindles and of the shuttle frame, and the
band is drawn forward by hand until a sufficient length is formed to be engaged

page_text: with the radial blocks 43 of the cylinder 42 and to be fastened to the reel, when the
machine requires no further attention until the wire 33 in the shuttle frame is
exhausted and the empty spool is then replaced by a filled one, its wire connected,
and the machine again put in motion.
The proper tension of the filling wire is maintained by a spring 51 Figure 8 or
by other suitable means.
It is important also to notice that it is necessary that the relation of the toothed
portions of the segmentally flanged wheels shall be such that they shall cause no
more than one complete revolution of the spindles, so that starting from the positions
shown in Figure 2, they shall return to that position for the next stroke of the
shuttle block which reverses the laterally shifting action of its frame.
It is also important to notice that the drawing of the wires by the continuous
action of the matrix wheel prevents any slack in the wires at the point of twisting,
because the wires are drawn from their respective spools toward and from such
points and being connected to each other at their points of engagement with said
wheel there can be no unequal drawing of them. Referring to Figure 1 the arrows
show the direction in which the band is drawn, and also the wires from the front
journals of each spindle and from the front journal of the twisting shuttle; and in
this figure is seen how the band is formed just at the ends of the journals and
between them the roller support 40 and that the twisting shuttle is in position to
be rotated outward with the spindle 25 to intertwist the wires 33 and at the point
and from which point as the band is drawn forward, the cams shift the shuttle
blocks and with them the twisting shuttle to bring the journals of the latter over
and into co-incident relation to the journals of the spindle 24 and thereby carry the
filling wire diagonally across the space between the line wires, where the filling
wire is twisted with the line wire 61 by the outward rotation of the co-incident parts,
and it is this laterally shifting of the twisting shuttle, and the co-acting rotation
of the spindles each in a constant direction opposite to the other which causes the
filling wire to be fed off the spool and be twisted over the line wires from opposite
sides of the band as stated.
It will of course be understood that the speed of the drawing matrix wheel, the
take up reel, and the operation of the shuttle and twisting devices are in unison,
and that the matrix wheel serves to support the formed band in horizontal and
longitudinal alignment with the band forming devices and to deliver it at a fixed
speed in smooth condition to the winding reel. For this purpose the surface blocks
of the matrix wheel are disposed in such a manner as to stand within the diagonal
strands of the filling wire and between the line wires, to lay and even the band
wires and to support them under the drawing action of the matrix wheel in proper
alignment with the wire carrying spindles. It will also be understood that the
sliding boxes 27 may be formed with or independently of the cam abutting pins, and
the said boxes may be retained in position on the head blocks by any suitable means
which will limit their reciprocating movement for the purpose stated.
An important feature in the construction of my machine is the provision of a
pair of spindles for the two line wire each having a wire delivery passage at one
side of the axis of rotation, each rotated alternately in a constant direction opposite
to the other, and arranged in fixed relation on the frame, and a shuttle for the filling
wire having a wiré delivery passage at one side of its axis of rotation and having
an alternate lateral movement for coincident relation with and rotated by and with
each separate spindle, so that in each position the said co-incident parts as an
entirety has a constant direction opposite to the other when the said shuttle is
shifted thereto. In the operation of this coiling and intertwisting device it will be
observed that spindles are geared each to a separate mutilated gear for separate
and independent rotation in directions one constantly opposite to the other, and that
the shuttle is mounted for separate and independent lateral movement and for
rotation by and with each spindle, whereby the filling wire is coiled in alternately
opposite directions with each side of the band over the line wires and both the

page_text: filling and the line wires are intertwined with each other in successive cous along
the straight line wire in the way described to make a narrow band of ribbon braced
and stiffened as shown in Figure 12.
