I, HENRY EDWARD NEWTON, of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, 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:-
An important object of this invention is to provide a machine whereby wire for
electrical purposes may have applied to it an insulating covering consisting of a
spirally wound and lapping strip or strips of paper, the paper being applied with
adhesive substance, and forming, of itself, the insulating covering for the wire.
The improved machine comprises means for drawing forward the wire from one
reel at the feeding end of the machine, and winding it upon another reel at the
delivery end of the machine, a rotary spindle through which the wire is passed,
together with means for supporting a bobbin of paper, for applying to the inner
side of the strip of paper an adhesive substance, such for example as a thin
solution of india rubber, and for condensing or consolidating the spirally wound
paper, all carried by and revolving with the spindle, and preferably also devicés
revolving with the spindle for straightening the wire before the paper is applied
to it.
In connection with the spirally wound strip, the conducting wire may have
applied to it a spirally wound fine wire laid on beneath a strip of paper; and in
such case the fine wire is taken from a bobbin which is revolved with the spindle,
and is conducted beneath the strip of paper as the latter is wound spirally on
the conductor or main wire.
The fine wire,. spirally applied, will then serve to
conduct away induced currents.
The invention consists in the
combinations of parts hereinafter described and

page_text: pointed out in the claims; including novel features in the construction and
arrangement of the devices for straightening the wire; in the devices for sup-
porting and winding the strip of paper; in the means for applying adhesive
substance to the paper; in the devices for condensing or consolidating the spirally
wound paper upon the wire; in the means for producing the travel of the wire, or
drawing it forward through the machine; and in the means for supporting the
bobbin of fine wire, and laying the fine wire ou beneath the spirally wound strip
of paper, in case such fine wire is to be used.

Figs. 10 and 11 are respectively a plan and side view, on a larger scale, illus-
trating in detail a tension device through which the fine wire is conducted as it
leaves the bobbin.
Similar letters of reference designate corresponding parts in all the figures.
The frame of the machine may be of any suitable construction. As here shown,
it consists essentially of upright frames or standards A. A' A², which are connected
by longitudinal rails or stretchers A³ and tie-rods A-In or on the upright frames
or standards A A¹, are bearings a, wherein is journalled a short hollow spindle B.
which derives rotary motion, by a wheel and pinion 66, from a longitudinal
shaft C, on which is a cone pulley C for a driving belt.
At the feeding end of the machine is a reel or drum D, from which the wire W
is taken, and which is mounted in standards D-On the shaft of the reel or
drum D is a pulley or wheel 12, over which is placed a brake strap or band D³,
which is fastened at one end 2, and has a weight at the other end.
This or any other suitable brake arrangement serves to offer a resistance to
the rotation of the reel or drum D, and consequently the wire is drawn there-
from under suitable tension, which may be varied by increasing or diminishing the
weight 63.
Near the delivery end of the machine are arranged two drums or wheels E E¹,
the shafts of which are mounted in standards. or supports cc, and the latter of
which E is or may be placed slightly below the former E. A positive rotary
..otion is transmitted to the drum or wheel E' from the shaft C through a short
upright shaft connected by a bevel wheel and pinion 2 with the shaft of the
dram or wheel E, and connected by a worm wheel and worm or screw c¹ c³ with
the shaft, as best shown in Fig. 2.
The drum or wheel E is also slightly out of line with the positively driven drum
or wheel E, so that the wire W may pass at the side of the former to the top of

page_text: the latter, and the wire is then passed back and forth, and between and around the
two drums or wheels, as many times as desirable, and finally leaves the top of
the drum E, and is passed to a reel or drum F, the shaft of which is supported
in standards F¹ beyond the delivery end of the machine, and which is rotated by
a belt F2 passed around a pulley E2 on the shaft of the drum E' and a pulley Fon
the shaft of the reel or drum F.
The reel or drum F is driven at a speed sufficient to take up the covered wire,
and the belt F will slip if the speed of the reel or drum exceeds the speed at
which the wire is drawn forward by the drums or wheels E E¹.
These latter wheels or drums are grooved circumferentially, as shown in Fig. 3,
to receive the wire, and from said Figure it will be observed that the grooves are
of varying depths, the depth gradually decreasing from one side of the drum
towards the other.
The groove at the outer side of the drum E' which first receives the wire, is
deepest, and consequently that portion of the drum around which the wire first
passes is smallest in diameter.-The groove d' at the opposite side of the drum is
shallowest, and consequently the diameter of the drum at the bottom of the groove
is greater.
The result of this increase in diameter of the drums at the bottom of the grooves,
from one side towards the other of the drum, is that the covered wire is kept
under strong tension, or slightly stretched, between the drums E E', and as no slip
will occur between the drums and the wire, the latter will be drawn forward at à
positive speed by the positive rotation of the drum. E¹, and a uniform degree
of lap will be maintained in the strip of paper wound spirally, as hereinafter
described. Obviously the same effect would be produced by making the drums
Every slightly conical, with grooves of uniform depth from side to side.
Connected and rotating with the spindle B, is a frame B', which has at one end
a lube, whereby it is secured fast to the spindle, and at the end a hub and a
journal e, whereby its outer end is supported in a bearing 3 formed in a
standard A, thus providing for the rotation of the frame B1 with the spindle B.
The journal 2 is hollow, and in that end of the frame is a socket or seat c*, here
shown as square, and in which is fitted a die block f, of corresponding shape, as
shown in Fig. 6. This block, which may be of wood, is shown as made in two
paris, to enable it to be readily taken out and off the wire, and the hole in it is
larger than the covered wire; and it is not designed to exert a pressure thereon, it
being intended only to keep the wire central, and prevent its contact with the
interior of the hollow journal, e².
G designates a strip of paper, which is taken from a bobbin or roll G', as best.
shown in Fig. 4. The bobbin or roll G is journalled on an arm H, which projects
at an angle from the spindle B, and is provided with fast and loose flanges 9 g',
between which the bobbin is placed. The loose flange g¹ is pressed against the
bobbin, and thereby forces the latter against the fixed flange, by means of a
spring applied to the arm H, and the tension of which may be varied by a
screw and nut at the end of the arm. The arm. H being non-rotary, the
confinement of the bobbin G' between the two flanges y g¹ produces a frictional
resistance to the turning of the bobbin, which is necessary in drawing off the
strip G, and by adjusting the power of the spring g, the proper tension on the
strip may be maintained."
I
The inner end of the arm H is forked at h, and is pivotted by bolts 1 to the
spindle B, so as to afford provision for setting and securing the arm at any desired
angle relatively to the spindle. These bolts should not however pass through
the spindle transversely, as they would then interfere with the travel of the wire W
through the spindle.
The angle of the arm relatively to the spindle will have to be varied for winding
wire of different sizes, and the spindle B is shown as provided with several holes 2
for the bolts ', whereby provision is afforded for securing the arm H in different

page_text: positions on the spindle. It may also be necessary to provide arms longer or
shorter than that shown for use, as may be found desirable under different
.conditions.
I designates a box or receptacle for adhesive substance, across or over which the
paper strip G is drawn as it passes from the bobbing to the wire W, and the
form and construction of which are shown in Figs. 4. 7, and 8.—It has a filling
hole or aperture i, which is tightly closed by a plug, and its discharge aperture
is closed by the strip G passing over it.
At the ends of the discharge aperture aró projecting horns or arms, which
guide the strip, and the strip is caused to hug the box at the aperture by means
of guides or bars at opposite sides thereof, and under which the strip passes, as
best shown in Fig. S.
But very little adhesive substance is required to be applied to the covering
strip G, and the quantity which the strip receives, by being drawn across the
aperture, is ample.
During fully half of each rotation of the spindle B, the discharge aperture is
in such position that the substance would run in quantity from the box, where its
aperture not covered by the strip, and during the remainder of each rotation the
film of substance which adheres to the sides of the aperture it is sufficient to
insure a continuous application of adhesive substance to the strip..
The box or reservoir is revolved as the spindle is rotated, and its supports
must be such, that it may be adjusted to the line of travel of the strip, according
as the arm I is shifted. As here shown, an arm I is secured by a bolt to the
hub e of the frame B.-This arm is slotted, and to it is adjustably secured, by a
bolt, a bar or arm 1, which has two slots 3. 4.-The box or reservoir i has
projecting lugs or ears adjustably secured to the bar or arm F by bolts 17 passing
through the slot 3.
The box I being thus supported, is afforded ample facility of adjustment, and as
it is revolved with the spindle, and around the wire, it is turned upside down, and
the adhesive substance which it contains is applied continuously and uniformly to
the strip G passing across its delivery or discharge aperture i'.
It is preferred to straighten the wire before the paper is applied, and to this end
fingers or dies j, one of which bears on the one side of the wire, and the other two
of which bear on the other side of the wire, are attached to the frame B'.
These fingers or dies may be slightly notched at *, to properly hold the wire
while under their action, and as they rotate or revolve with the frame B', they
easily and accurately straighten the forwardly moving wire.
The fingers or dies are or may be slotted, and are secured to the frame 1 by
bolis, the frame being also slotted. Provision is thus afforded for adjusting the
fingers, or dies, j, to positions in which they will operate most effectively.
Attached to the frame B' near its forward end, are other fingers, which bear on
opposite sides of the wire. These fingers or dies, as they turn with the spindle
and frame, act on the paper covering to consolidate or condense the paper, and the
paper is not abraded or torn by them, as would be probable were the wire drawn
through a stationary die. The fingers are slotted, and are secured to the slotted
frame B by bolts Z', whereby provision is afforded for adjusting them to the
positions in which they will operate most effectively-One or more of the fingers
or dies, is or may be notched at to hold the wire centrally.
It will be understood that the number of straightening fingers or dies j, or the
number of fingers or dies, is not limited, although only three of each are shown
in the drawings.
When it is desired to wind a small wire around the wire W, and on the inner
side of the paper strip, a hobbin is attached to the spindle B or frame B', so that it
will be revolved therewith.
A bobbin of fine wire, supported in a frame /, which may be attached to the
bolt is shown in Fios 7 and

page_text: By turning the pivot or shaft on which this bobbin is journalled, the power of
a spring may be increased or diminished, the frictional resistance to the rotation
of the bobbin being thereby varied.
From the bobbin, 7, the small wire is passed through a tension device J, the
construction of which is best shown in Figs. 10 and 11-16 consists of a base or
stock me, which is to be removably secured in the slot 4 of the bar or arm P.-
On the stock m is pivotted a roller or small sheave m', and in the stock are two
pins mm, the former of which is perforated for the passage of the wire from
the bobbin Z.
The wire is first passed through the upper perforation or eye in the stud or
pin m², thence around the sheave or roller m', and finally inside the stud or pin m³,
whence it passes around or over a small pulley or sheave mt, and thence to the
wire 3 I around which it is wound spirally, slightly in advance of the strip G.
When it is not desired to apply the fine wife, the bobbin 7 and tension device J
are removed.
The wire or conductor may be passed through the machine two or three times,
in order to apply as many coverings or strips of paper.
When a fine wire is to be applied as described, the main wire is first passed one
or more times through the machine, to apply one or more strips, in order that the
fine wire, when applied, will be properly insulated from the main wire, and the
fine wire is then applied at the same time with another strip of paper, after which
one or more additional strips of paper are applied, to effectively insulate the fine
wire.
Although this machine is more particularly intended for applying paper strips, it
is or may be applicable to machines for applying strips of fibrous material other
than paper.

.
1
In connection with the spirally wound strip, the conducting wire may have
applied to it a spirally wound fine wire laid on beneath a strip of paper; and in
such case the fine wire is taken from a bobbin which is revolved with the spindle,
and is conducted beneath the strip of paper as the latter is wound spirally on
the conductor or main wire. The fine wire, spirally applied, will then serve to
conduct away induced currents.
f
The invention consists in the combinations of parts hereinafter described and
pointed out in the claims; including novel features in the construction and.
arrangement of the devices for straightening the wire; in the devices for 'sup-
porting and winding the strip of paper; in the means for applying adhesive

and the strip of paper being drawn past and over said box.
Fig. 9 is a detail view illustrating the bobbin of fine wire and its supporting
frame, and
Figs. 10 and 11 are respectively a plan and side view, on a larger scale, illus-
trating in detail a tension device through which the fine wire is conducted as it
leaves the bobbin.
Similar letters of reference designate corresponding parts in all the figures.
The frame of the machine may be of any suitable construction. As here shown,
it consists essentially of upright frames or standards A A¹ A³, which are connected
by longitudinal rails or stretchers A³ and tie-rods A*-In or on the upright frames
or standards A. A¹, are bearings a, wherein is journalled a short hollow spindle B,
which derives rotary motion, by a wheel and pinion 6 61, from a longitudinal
shaft C, on which is a cone pulley C¹ for a driving belt.
At the feeding end of the machine is a reel or drum D, from which the wire W
is taken, and which is mounted in standards D¹-On the shaft of the reel or
drum D is a pulley or wheel D³, over which is placed a brake strap or band D³,
which is fastened at one end 6', and has a weight 63 at the other end.
This or any other suitable brake arrangement serves to offer a resistance to
the rotation of the reel or drum D, and consequently the wire is drawn there-
from under suitable tension, which may be varied by increasing or diminishing the
weight 6³
Near the delivery end of the machine are arranged two drums or wheels E E¹,
the shafts of which are mounted in standards or supports cc, and the latter of
which E is or may be placed slightly below the former E. A positive rotary
motion is transmitted to the drum or wheel E' from the shaft through a short
upright shaft c' connected by a bevel wheel and pinion c³ with the shaft of the
drum or wheel E, and connected by a worm wheel and worm or screw c c with
the shaft, as best shown in Fig. 2.
The drum or wheel E is also slightly out of line with the positively, driven drum
or wheel E', so that the wire W may pass at the side of the former to the top of
the latter, and the wire is then passed back and forth, and between and around the
two drums or wheels, as many times as desirable, and finally leaves the top of
the drum E, and is passed to a reel or drum F, the shaft of which is supported
in standards F¹ beyond the delivery end of the machine, and which is rotated by

page_text: a belt F passed around a pulley E on the shaft of the drum E" and a pulley Fº on
the shaft of the reel or drum F.
The reel or drum F is driven at a speed sufficient to take up the covered wire,
and the belt F' will slip if the speed of the reel or drum exceeds the speed at
which the wire is drawn forward by the drums or wheels E.E¹.
These latter wheels or drums are grooved circumferentially, as shown in Fig. 3,
to receive the wire, and from said Figure it will be observed that the grooves are
of varying depths, the depth gradually decreasing from one side of the drum
towards the other.
The groove d at the outer side of the drum E¹ which first. receives the wire, is
deepest, and consequently that portion of the drum around which the wire first
passes is smallest in diameter.-The groove d¹ at the opposite side of the drum is
shallowest, and consequently the diameter of the drum at the bottom of the groove
is greater.
The result of this increase in diameter of the drums at the bottom of the grooves,
from one side towards the other of the drum, is that the covered wire is kept
under strong. tension, or slightly stretched, between the drums E E¹, and as no slip
will occur between the drums and the wire, the latter will be drawn forward at a
positive speed by the positive rotation of the drum E¹, and a uniform degree
of lap will be maintained in the strip of paper wound spirally, as hereinafter
described. Obviously the same effect would be produced. by making the drums
E E¹ very slightly conical, with grooves of uniform depth from side to side.
Connected and rotating with the spindle B, is a frame B¹, which has at one end
a hub e, whereby it is secured fast to the spindle, and at the end a hub and a
journal e¹ e, whereby its outer end is supported in a bearing e³ formed in a
standard A³, thus providing for the rotation of the frame B" with the spindle B.
The journal e' is hollow, and in that end of the frame is a socket or seat e*, here
shown as square, and in which is fitted a die block f, of corresponding shape, as
shown in Fig. 6. This block, which may be of wood, is shown as made in two
parts, to enable it to be readily taken out and off the wire, and the hole in it is
larger than the covered wire; and it is not designed to exert a pressure thereon, it
being intended only to keep the wire central, and prevent its contact with the
interior of the hollow journal, e².
G designates a strip of paper, which is taken from a bobbin or roll G¹, as best
shown in Fig. 4: The bobbin or roll G¹ is journalled on an arm H, which projects
at an angle from the spindle B, and is provided with fast and loose flanges g g',.
between which the bobbin is placed. The loose flange g¹ is pressed against the
bobbin, and thereby forces the latter against the fixed flange, by means of a
spring g² applied to the arm H, and the tension of which may be varied by a
screw and nut g3 at the end of the arm. The arm H being non-rotary, the
confinement of the bobbin G¹ between the two flanges g g' produces a frictional
resistance to the turning of the bobbin, which is necessary in drawing off the
strip G, and by adjusting the power of the spring 92, the proper tension on the
strip may be maintained.
The inner end of the arm H is forked at h, and is pivotted by bolts h¹ to the
spindle B, so as to afford provision for setting and securing the arm at any desired
angle relatively to the spindle. These bolts h¹ should not however pass through
the spindle transversely, as they would then interfere with the travel of the wire W
through the spindle.
The angle of the arm relatively to the spindle will have to be varied for winding
wire of different sizes, and the spindle B is shown as provided with several holes h³
for the bolts h¹, whereby provision is afforded for securing the arm H in different
positions on the spindle. It may also be necessary to provide arms longer or
shorter than that shown for use, as may be found desirable under different
conditions..
I designates. a. box or receptacle for adhesive substance, across or over which the
paper strip G is drawn as it passes. from the bobbin G to the wire W, and the

page_text: form and construction of which are shown in Figs. 4. 7, and 8.-It has a filling
hole or aperture i, which is tightly closed by a plug, and its discharge aperture
is closed by the strip G passing over it.
At the ends of the discharge aperture ¹ are projecting horns or arms.³, which
guide the strip, and the strip is caused to hug the box at the aperture ¹ by means
of guides or bars at opposite sides thereof, and under which the strip passes, as
best shown in Fig. 8.
But very little adhesive substance is required to be applied to the covering
strip G, and the quantity which the strip receives, by being drawn across the
aperture ¹, is ample.
During fully half of each rotation of the spindle B, the discharge aperture 2¹ is
in such position that the substance would run in quantity from the box, were its
aperture not covered by the strip, and during the remainder of each rotation the
film of substance which adheres to the sides of the aperture ¹ is sufficient to
insure a continuous application of adhesive substance to the strip.
The box or reservoir I is revolved as the spindle is rotated, and its supports
must be such, that it may be adjusted to the line of travel of the strip, according
as the arm H is shifted. As here shown, an arm I' is secured by a bolt to the
hube of the frame B.-This arm is slotted, and to it is adjustably secured, by a
bolt, a bar or arm 12, which has two slots 3. 4.-The box or reservoir I has
projecting lugs or ears 26 adjustably secured to the bar or arm I' by bolts 27 passing
through the slot 3.
The box I being thus supported, is afforded ample facility of adjustment, and as
it is revolved with the spindle, and around the wire, it is turned upside down, and
the adhesive substance which it contains is applied continuously and uniformly to
the strip G passing across its delivery or discharge aperture 2.
It is preferred to straighten the wire before the paper is applied, and to this end
fingers or dies j, one of which bears on the one side of the wire, and the other two
of which bear on the other side of the wire, are attached to the frame B¹.
These fingers or dies may be slightly notched at *, to properly hold the wire
while under their action, and as they rotate or revolve with the frame B¹, they
easily and accurately straighten the forwardly moving wire.
The fingers or dies jare or may be slotted, and are secured to the frame B¹ by
bolts, the frame being also slotted.-Provision is thus afforded for adjusting the
fingers, or dies, j, to positions in which they will operate most effectively.
Attached to the frame B¹ near its forward end, are other fingers, which bear on
opposite sides of the wire. These fingers or dies, as they turn with the spindle
and frame, act on the paper covering to consolidate or condense the paper, and the
paper is not abraded or torn by them, as would be probable were the wire drawn
through a stationary die. The fingers k are slotted, and are secured to the slotted
frame B by bolts k', whereby provision is afforded for adjusting them to the
positions in which they will operate most effectively.-One or more of the fingers
or dies j, k is or may be notched at to hold the wire centrally.
It will be understood that the number of straightening fingers or dies j, or the
number of fingers or dies k, is not limited, although only three of each are shown
in the drawings.
When it is desired to wind a small wire around the wire W, and on the inner
side of the paper strip, a bobbin is attached to the spindle B or frame B¹, so that it
will be revolved therewith.
A bobbin of fine wire, supported in a frame , which may be attached to the
bolt, is shown in Figs. 7 and 9.
By turning the pivot or shaft 12 on which this bobbin is journalled, the power of
a spring may be increased or diminished, the frictional resistance to the rotation
of the bobbin being thereby varied.
From the bobbin, l, the small wire wis passed through a tension device J, the
construction of which is best shown in Figs. 10 and 11.-It consists of a base or
stock m, which is to be removably secured in the slot 4 of the bar or arm I³.-

page_text: On the stock m is pivotted a roller or small sheave m¹, and in the stock are two
pins m² m³, the former of which is perforated for the passage of the wire w from
the bobbin l.
The wire w is first passed through the upper perforation or eye in the stud or
pin m², thence around the sheave or roller m¹, and finally inside the stud or pin m³,
whence it passes around or over a small pulley or sheave m², and thence to the
wire w, around which it is wound spirally, slightly in advance of the strip G.
When it is not desired to apply the fine wire, the bobbin and tension device J.
are removed.
The wire or conductor may be passed through the machine two or three times,
in order to apply as many coverings or strips of paper.
When a fine wire is to be applied as described, the main wire is first passed one
or more times through the machine, to apply one or more strips, in order that the
fine wire, when applied, will be properly insulated from the main wire, and the
fine wire is then applied at the same time with another strip of paper, after which
one or more additional strips of paper are applied, to effectively insulate the fine.
wire.
Although this machine is more particularly intended for applying paper strips, it
is or may be applicable to machines for applying strips of fibrous material other
than paper.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:-
1. The combination with a rotary spindle. and mechanism connected therewith,
