We, CARL HARMANN, of Neustadt, near Vienna, Austria, and THEODOR GECK, of
Altena, in Westphalia, Germany, Manufacturers, do hereby declare the nature of this
invention to be as follows:
The present invention relates to a wire-drawing machine which is adapted to draw
several wires through a number of draw-plates in one operation, and to wind then
on bobbins of any required size by means of a bobbin-winder set in motion. by the
same driving mechanism, or on winding drums corresponding in number to the
number of wires, or to draw several wires in a single or double draught on draw-
rollers corresponding in number to the spindles.
In the following description reference will be made to the accompanying drawings,
Sheets I to III, which illustrate the invention both as regards the general arrange-
ment and the details of construction.
Sheet I represents a wire-drawing machine baving 7 vertical spindles a, b, of which
the spindle a receives its rotary motion from a horizontal shaft E situated underneath
the table, through the intermediary of suitable bevel wheels d, d', while the other
spindles b are driven from the spindle a by means of a pitch chain C and chain
wheels a¹, b', at a speed corresponding to the elongation of the wire by each passage
through one of the draw plates.
On the vertical spindles a and b are mounted a series of draw-rollers, which are
adjustable vertically for utilizing the entire height available for drawing the wires.
These rollers are turned off conically, so that their diameter at the top is a few milli-
metres less than that at the botton, in order that the wire may constantly tend to
slide upward and not cut grooves in the draw-rollers.
The machine represented by Sheet I, Figs. 1 to 3, is constructed for 21 individual
operations or drawings and 3 bobbins, consequently there are three draw rollers
the spindles b
mounted on each of the seven spindles. The draw rollers on
have the same diameter and the drawrollers on the spindle a have also the same
diameter.
The speed of revolution of the spindle a is less than that of the first spindle b,
in the same ratio as the diameter of its draw roller is greater than that of the draw
rollers on the said spindle.
In front of every group of draw rollers (the latter being arranged in groups of
three piled one upon the other) there is mounted a holder h which is vertically
adjustable like the said rollers, and serves to hold one of the drawplates e, between
any two consecutive groups or trios of draw-rollers there is inserted a trough F. for
the pickling liquid.
This trough stands on a virtically adjustable frame and has on the inlet and outlet
side (viz. where the wire enters and where it leaves the trough) a slot which is
covered with a slotted india-rubber plate. These slots serve to guide the wire S
through the pickling trough and into the orifice of the drawplates, while the india-
rubber plate serves to clean the wire and to retain any superfluous pickling liquor in
the trough

page_text: The horizontal main driving shaft E situated under the table carries at one end
a small bevel wheel d², by means of which and the corresponding bevel wheel d³ it
imparts motion to a transverse shaft E¹, on which are mounted two chain wheels k, k
and a pair of movable coupling sleeves K, K¹ adapted to engage with the said chain
wheels. The chains of these wheels pass over a pair of corresponding chain
wheels,, mounted on a horizontal shaft E, and serving to drive the same
alternately, the wheel k being coupled with the shait E1, when the wheel, is out of
gear, and vice-versa.
The transverse shaft E2 serves to drive the vertical spindles v1, v2, v3, by means of
bevel-gears d, d, which spindles are adapted to drive the bobbins V, VV for winding
up the finished wire.
On each extremity of the shaft E¹ is mounted a crank disc Z connected with
a vertically movable frame R by means of connecting rods and vertical guide
rods m.
The bobbins V are supported by the frame R and adapted to slide up and
down on the spindles v1, v2, v3³, while being turned by the same. Consequently, the
turning of the shaft E¹ causes the bobbins V, V, V, to move up and down on their
respective spindles.
Sheet II, Figs. 1 to 3 shows the same multiple wire drawing machine with 21
winding rollers, but instead of the three hobbins V, shown on Sheet I, the machine
has three winding drums A, A, and A In order that these drums may be mounted
in their proper places, the spindle v² is composed of two lengths screwed together
at i, Fig. 3, Sheet 1.
To convert a machine from the form shown on Sheet I into that shown on Sheet II,
the frame R is detached from the guide rods m and lifted, together with the
bobbins V, until it is clear of the spindles v1, v2, v3, the connecting rods and guide
rods m are removed from the crank discs Z, the upper part of the spindle is
screwed off, the winding drums A₁, A, are mounted on the respective spindles v
and v³, the draw rollers B1, B2, B3 are removed from the spindle a and replaced by
the third winding drum A provided with three grooves 1, 2, 3, as shown on
Sheet II.
As the winding drums A, A, and A₂ have equal diameters, they should have the
same speed of revolution, which is attained by setting the coupling sleeve K¹ out of
gear and setting the sleeve K in gear with the wheel k. After this, the machine is
ready to draw wires and to wind them on the drums.
Sheet III, Figs. 1 and 2, represents the same machine modified so that it will
draw 7 wires once or twice through 7 draw plates (one for each wire).
The common driving chain C, passing over the chain wheels a¹, 61, is for this
purpose, taken off the said wheels and laid on the chain wheels a², 62, mounted on
the same vertical shafts a, b, the chain wheels a², 62, having equal diameters, so as
to impart to the said shafts a and b. the same angular velocity. The draw
rollers B1, B2, B3, shown on Sheet I are removed and replaced by drums A and A²:
the pickling troughs F are removed and may be inserted between the drawing
drums, and the corresponding winding drums &; the draw plate holders h are
taken out of their socket pieces h¹ and inserted into the socket pieces h².
The method of working with the various forms of wire-drawing machine is as
follows:-
To use the machine in the form represented by Sheet I, the wire s drawn off the
spool (not shown) is caused to pass through the first draw-plate e to the first roller B¹
of the first triple draw roller and wound on this roller two or three times; thence it
is guided through the first pickling trough F situated between the first and the
second group of draw-rollers. The wire coming from this trough passes in the same
manner through the draw-plate mounted in the second draw plate holder to the draw
roller B¹ of the second group, and this operation is repeated from roller to draw plate
and from draw plate to roller, until the wire has passed through all draw-plates and
round each of the rollers B¹. From the last of the series of rollers (viz. the large
roller mounted on shaft a) the wire is led through a suitable tension-regulator to the
first of the bobbins V, and wound on the same as a finished product. As the bobbin V

page_text: is constantly raised and lowered by the crank discs Z, the finished wire will be dis-
tributed evenly over the entire length of the bobbin.
A similar process takes place with the other wires corresponding to the number of
bobbins, said wires being guided over the rollers B, or B, and through the draw
plates e supported by the draw-plate holder h at a suitable height.
With the machine represented by Sheet II, the method of operation is the same
as that described above, except that the wires S1 and S2, after having passed through
the series of draw plates, are wound two or three times over the sections one or two
of the winding drum A, and thence over guide rollers to the winding drum A¹ or A2,
on which they are wound as a finished product. The last wire (in the present
example S³) passes from the last groove of the drum A (section 3) through a guiding
apparatus to the mantle of the drum A, and is wound on the same.
After the machine has been converted into the shape represented by Sheet III, the
individual wires are drawn in the same manner as on ordinary wire-draw benches
with single or double action. To draw each wire once only, it is drawn directly on
the mantle of the drum A².
In the second case, however, the wire, after having passed through the first draw-
plate, is guided over the grooved part of the drum A2, thence over the stnall guide
roller to the second draw-plate and through the same to the circumference of the
drum A2.
Fine wire, which has to be dressed, may be drawn through a draw-plate on to the
grooved part of the drum A, Fig. 2, and then guided through the dressing apparatus n
on to the mantle of the druin.
If the machine is arranged as shown by Sheet III, the bobbin winder is set in
motion as before, although not used in connection with the drawing rollers or druins.
It may therefore be used as an independent bobbin winder or spooling apparatus, as
indicated by Figs. 1 and 2. The construction of the bobbin winder is shown by
Fig. 3.

We, CARL HARMANN, of Neustadt, near Vienna, Austria, and THEODOR GECK, of
Altena, in Westphalia, Germany, Manufacturers, 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 :—
The present invention relates to a wire-drawing machine which is adapted to draw
several wires through a number of draw-plates in one operation, and to wind them on
bobbins of any required size by means of a bobbin-winder set in motion by the same
driving mechanism, or on winding drums corresponding in number to the number of
wires, or to draw several wires in a single or double draught on draw rollers
corresponding in number to the spindles.
In the following description reference will be made to the drawings, Sheets I to III,
filed with the Provisional Specification which illustrate the invention both as regards
the general arrangement and the details of construction.
Sheet I represents a wire-drawing machine having 7 vertical spindles a, b, of which
the spindle a receives its rotary motion from a horizontal shaft E situated underneath
the table, through the intermediary of suitable bevel wheels d, d, while the other
spindles 6 are driven from the spindle a by means of a pitch-chain C and chain

page_text: wheels a, b, at a speed corresponding to the elongation of the wire by each passage
through one of the draw-plates.
On the vertical spindles a and b are mounted a series of draw-rollers, which are
adjustable vertically for utilizing the entire height available for drawing the wires.
These rollers are turned off conically, so that their diameter at the top is a few milli-
metres less than that at the bottom, in order that the wire may constantly tend to
slide upward and not cut grooves in the draw-rollers.
The machine represented by Sheet I, Figs. 1 to 3 is constructed for 21 individual
operations or drawings and three bobbins; consequently there are three draw-rollers
mounted on each of the seven spindles. The draw-rollers on the spindles b have the
same diameter, and the draw-rollers on the spindle a have also the same diameter.
The speed of revolution of the spindle is less than that of the last spindle b, in
the same ratio as the diameter of its draw-roller is greater than that of the draw-
rollers ou the said spindle.
In front of every group of draw-rollers (the latter being arranged in groups of
three piled one upon the other) there is mounted a holder which is vertically
adjustable like the said rollers, and serves to hold one of the drawplates e; between
any two consecutive groups or trios of draw-rollers there is inserted a trough F for
the pickling liquid.
This trough stands on a vertically adjustable frame and has on the inlet and outlet
side (viz. where the wire enters and where it leaves the trough) a slot which is covered
with a slotted india-rubber plate. These slots serve to guide the wire S through the
pickling trough and into the orifice of the draw-plates, while the india-rubber plate
serves to clean the wire and to retain any superfluous pickling liquor in the trough.
The horizontal main driving shaft E situated under the table carries at one end a
small bevel wheel 2, by means of which and the corresponding bevel wheel d³ it
imparts motion to a transverse shaft E¹, on which are mounted two chain wheels k, k¹
and a pair of movable coupling sleeves K, K¹ adapted to engage with the said chain
wheels. The chains of these wheels pass over a pair of corresponding chain
wheels, mounted on a horizontal shaft E2 and serving to drive the same
alternately, the wheel being coupled with the shaft E', when the wheel k¹ is out of
gear, and vice versa.
The transverse shaft E2 serves to drive the vertical spindles v1, v2, v3, by means of
bevel-gears d₁, dg, which spindles are adapted to drive the bobbins V, VV for winding
up the finished wire.
On each extremity of the shaft E¹ is mounted a crank disc Z connected with a
vertically movable frame R by means of connecting rods and vertical guide rods m.
The bobbins are supported by the frame R and adapted to slide up and down on the
spindles v1, v2, 3, while being turned by the same. Consequently, the turning of the
shaft E¹ causes the bobbins V, V, V, to move up and down on their respective
spindles.
Sheet II, Figs. 1 to 3, shows the same multiple wire drawing machine with 21 winding
rollers, but instead of the three bobbins V, shown on Sheet 1, the machine has three
winding drums A, A¹ and A². In order that these drums may be mounted in their
proper places the spindle v2 is composed of two lengths screwed together at i, Fig. 3,
Sheet I.
To convert a machine from the form shown on Sheet I into that shown on Sheet II,
the frame R is detached from the guide rods m and lifted, together with the
bobbins V, until it is clear of the spindles v1, v2, v3, the connecting rods and guide
rods m are removed from the crank discs Z, the upper part of the spindle 2 is screwed
off, the winding drums, A¹ A2, are mounted on the respective spindles v¹ and v³, the
draw rollers B1, B2, B3, are removed from the spindle a, and replaced by the third
winding drum A provided with three grooves 1, 2, 3, as shown on Sheet II.
As the winding drums A, A1 and A2 have equal diameters, they should have
the same speed of revolution which is attained by setting the coupling sleeve K¹ out
After this the machine is
of gear and setting the sleeve K in gear with the wheel k.
ready to draw wires and to wind them on the drums.

page_text: Sheet III, Figs. 1 and 2, represents the same machine modified so that it will
draw seven wires once or twice through seven draw-plates (one for each wire).
The common driving chain C, passing over the chain wheels a¹ b', is for this
purpose taken off the said wheels, and laid on the chain wheels a², 62, mounted
on the same vertical shafts a, b, the chain wheels a², b2 having equal diameters,
so as to impart to the said shafts a and b the same angular velocity. The draw-
rollers B1, B2, B3, shown on Sheet I are removed and replaced by drums A and A²;
the pickling troughs F are removed and may be inserted between the drawing drums
and the corresponding feed-drums G; the draw-plate holders h are taken out of
their socket pieces and inserted into the socket pieces h².
The method of working with the various forms of wire drawing machine is as
follows:-
To use the machine in the form represented by Sheet I, the wire s drawn off the
spool (not shown) is caused to pass through the first draw-plate e to the first roller B¹
of the first triple draw roller, and wound on this roller two or three times; thence it
is guided through the first pickling trough F situated between the first and the second
group of draw-rollers.
The wire coming from this trough passes in the same manner
through the draw plate mounted in the second draw plate holder to the draw roller B¹
of the second group, and this operation is repeated from roller to draw plate and
from draw plate to roller until the wire has passed through all draw plates and
round each of the rollers B¹. From the last of the series of rollers (viz. the large roller
mounted on the shaft a) the wire is led through a suitable tension-regulator to the first
of the bobbins V, and wound on the same as a finished product. As the bobbin V
is constantly raised and lowered by the crank discs Z, the finished wire will be
distributed evenly over the entire length of the bobbiu.
A similar process takes place with the other wires corresponding to the number of
bobbins, said wires being guided over the rollers B2 or B3 and through the draw
plates e supported by the draw plate holder h at a suitable height.
With the machine represented by Sheet II, the method of operation is the saine as
that described above, except that the wires s¹ and 82, after having passed through the
series of draw plates are wound two or three times over the sections I or II of the
winding drum A, and thence over guide rollers to the winding drum A¹ or A², on
which they are wound as a finished product. The last wire (in the present example s³)
passes from the last groove of the drum A (section 3) through a guiding apparatus
to the mantle of the drum A, and is wound on the same.
After the machine has been converted into the shape represented by Sheet III, the
individual wires are drawn in the same manner as on ordinary wire draw-benches with
single or double action. To draw each wire once only, it is drawn directly on the
mantle of the drum A2 Such an arrangement is suitable for the, treatment of soft
or galvanized wires.
In the second case, however, the wire after having passed through the first draw
plate, is guided over the grooved part of the drum A2, thence over the small guide
roller to the second draw plate and through the same to the circumference of the
drum A²
Fine wire, which has to be dressed, may be drawn through a draw-plate on to the
grooved part of the drum A, Fig. 2, and then guided through the dressing apparatus n
on to the mantle of the drum.
If the machine is arranged as shown by Sheet III, the bobbin winder is set
in motion as before, although not used in connection with the drawing rollers or
drams. It may therefore be used as an independent bobbin winder or spooling
apparatus, as indicated by Figs. 1 and 2. The construction of the bobbin winder
is shown by Fig. 3.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is

page_text: winder (Sheet I) adapted to be set in motion from the main-driving shaft E of the
machine in such a manner, that the bobbins (V) are turned and also moved up and
down, in order to wind up continuously the wires drawn on the wire drawing machine,
or wires drawn by other means (Sheet III), and an alternative winding apparatus
chiefly consisting of drums (A', A2 Sheet. II) without up and down motion (the
mechanism for producing the same being set out of action).
2. The modified construction or arrangement of the wire drawing machine,
suitable for acting simultaneously on several soft or galvanised wires, substantially
as described.
3. The various forms of multiple wire drawing machines, as described and
shown by the drawings.
