Improvements in Continuous Wire-drawing Machines with
Iwo Tiers of Spindles.
I, WILLIAM JORDAN, of No. 120, Chancery Lane, London, England, Patent
Agent, do hereby declare the nature of this invention to be as follows:-
The present invention relates to a continuous wire-drawing machine for draw-
ing fine wire, and its nature comprises two tiers of spindles arranged one above
the other, and provided upon their opposite ends with drawing rolls, so that
wire may be drawn by the rolls upon both sides of both tiers.
This invention is performed by providing all of the drawing roll spindles in
both tiers with belt pulleys having a common alignment, and providing an end-
less belt looped over a driving pulley, and at one side of the loop extended back
and forth over all of the spindle pulleys.
This system of driving rotates the spindles of the two tiers in opposite direc-
tions, and permits the arrangement of one half the winding drums at one end
of the machine, and one half at the other.
This construction avoids the arrangement of the winding drums for the upper
tier above the winding drums for the lower tier.
The machine is constructed with two side frames connected by tie-bars, each
frame having a lower main piece formed upon its upper edge with a rail to sup-
port a series of bearings for the drawing roll spindles, which are extended across
the frames and provided with the drawing rolls upon their overhanging ends.
An upper rail is supported upon the lower rail by suitable feet, or standards,
and provided in like manner with bearings for the upper tier of drawing roll
spindles.
All the spindles are provided with belt pulleys in the middle between the
bearings. To carry the driving belt through the machine and back to the driv-
ing pulley, a return pulley is mounted beneath the lower spindle at one end of
the frame, and a guide pulley is supported at the opposite end of the frame, and
the endless belt, after extending back and forth over the spindle pulleys, is
carried under the return pulley and thence to the guide pulley and upwardly to
the driving pulley.
Each winding drum is provided with friction gearing and a clutch, so that
it may be stopped independently of the others.
The whole construction furnishes a multiplex machine adapted, with two
drawing rolls upon the opposite end of each spindle to draw at least eight wires
simultaneously, and may be used to draw more wires by furnishing three or more
drawing rolls upon the ends of each spindle.

Two Tiers of Spindles.
I, WILLIAM JORDAN, of No. 120, Chancery Lane, London, County of Middle-
sex, England, Agent, 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 that class of wire-drawing machines for draw-
ing fine wire, and its object is to furnish a multiplex machine adapted to draw
at least eight wires simultaneously, and designed to occupy very little more room
than the continuous machine for drawing one or more wires.
This object is attained by arranging two tiers of drawing roll spindles one
above the other, and providing them with belt pulleys having a common align-
ment, so that a single endless belt may be carried back and forth over all of the
pulleys and thus rotate the spindles in opposite directions. Two or more draw-
ing rolls may be mounted on both ends of each spindle, and corresponding wire
dies arranged between the spindles, and four or more wires may thus be drawn
simultaneously by the rolls of each tier.
The eight or more wires drawn by the rolls of both tiers require eight or more
winding drums to receive the wire, and great inconvenience will be produced if
such drums were all grouped at one end of the machine.
With the construction described, the wires drawn by each tier are delivered
upon different levels at the ends of the machine, and by the rotation of the two
tiers in opposite directions, the winding drums to receive the wire from the two
tiers may be arranged one half at each end of the machine. The winding drums
are provided with separate clutches, so that each may be stopped independently
when the wire breaks, or the drum is filled.
Each drum, and the set of dies which supplies the wire thereto, can thus be
operated with the same independence as if it were in a single wire machine.
To apply an endless driving belt readily to the pulleys in both tiers, it is
desirable to arrange a return pulley at one end of the machine under the lower
tier, and a guide pulley at the opposite end, from which the belt may be led
upwardly to the driving pulley.
The invention will be understood by reference to the annexed drawing, in
which Figs. 1 and 2 show respectively a plan and elevation of the principal
parts of a machine embodying my improvements, with a driving pulley repre-
sented diagrammatically above Fig. 2. Fig. 3 is a side elevation of one end of
the machine upon a larger scale; and Fig. 4 is an end view upon the same scale.
In Figs. 1 and 2, the fixtures are not shown for actuating the friction wheels
which are provided to drive the winding drums, as the scale is too small to show
such fixtures clearly. The machine is made with two side frames connected
by tie-bars, each frame having a lower main piece formed upon its upper edge
with a rail b, and an upper rail is supported upon such rail by feet or
standards d. The upper and lower rails are similarly provided with a series of
bearings (twelve being shown on each rail). and drawing roll spindles g are
extended across the frames through such bearings and each end of each spindle
is shown provided with two drawing rolls h.
The middle of each spindle is provided with a belt pulley i
Die-holders and dies are provided between the drawing rolls, and the wire o
is led from a suitable reel (not shown in the drawing) through the first die and
successively around the drawing rolls and through the other dies, as shown by

page_text: arrows P and q, as is common in continuous wire-drawing machines. The draw-
ing rolls and the spindles upon the rails c form the upper tier and deliver the wire,
per arrows p, at the right hand end of the frame, where winding drums j and k
are supported upon vertical shafts r and s. The rolls of the spindles upon the
rails 6 form the lower tier and deliver the wire, per arrows q, upon a lower
level, and drums and m are suitably mounted upon shafts rand's at the left
hand end of the frame to receive such wires. The return pulley t for the
driving belt is mounted beneath the spindles at the left end of the frame and is
furnished with an axle having an adjustable bearing u, the bearing being mov-
able on the frame by means of set screws. A guide pulley is supported by a
vertically adjustable axle w at the opposite end of the frame, and the driving
pulley is preferably located over such guide pulley.
An endless belt y "is looped over such driving pulley, and one side of the loop
is extended back and forth over the spindle pulleys i, being carried first under
the nearest pulley of the lower, tier, and carried last over the farthest pulley
of the upper tier. From such farthest pulley it is carried below the return
pulley and then along under the lower tier of spindles between the two frames
to the guide pulley, and from such guide pulley the opposite side of the loop
extends to the driving pulley a.
The belt is shown driven upwardly in its passage from the nearest pulley of
the lower tier, and downwardly in its passage from the guide roller to the
driving pulley, thus rotating the spindles of the lower tier to the left, and the
spindles of the upper tier to the right, as indicated by the arrows 2. The wire
is delivered by the lower tier of driving rolls at the left hand end of the machine,
and the winding drums and m mounted at a much lower level than the
drums and to receive the wire from such rolls.
Two drawing rolls are shown upon each end of each spindle, and four winding
drums are thus required for each tier of the rolls. The drums j and are set,
as shown in Figs. 1 and 4, opposite one another in pairs, and each pair driven
from a single clutch shaft, 1 which is rotated from the shaft w by chain gear-
ing 2.
The bevel friction pinions 3 and 4 are fitted movably upon splines on the
clutch shaft, adjacent to bevel friction wheels 5 and 6, which are fixed to the
shafts of the drums j and k respectively below and above the pinions 3 and 4.
Each movable pinion is provided with a clutch collar 7, and a pivoted fork 8;
and weighted levers 9 and 10 are fitted to the pivots of the forks upon the oppo-
site sides of the machine to operate the clutches for the drums and k respec-
tively. The pivots of the forks are arranged in pairs and extended outwardly
beyond the drums to receive the weighted levers 9, and are mounted upon the
framing of the drum shafts by bearings 12.
One of the fork-pivots or shafts, as shown in Fig. 3. is offset for a portion of
its length to clear the top of one of the bevel friction wheels 3. The pivot of the
fork is provided with a transverse pin 11, and the hub of each weighted lever is
fitted to turn loosely upon the pivot of the fork, and is notched to clear the pin
in its vertical position, but to strike the same upon opposite sides when turned
to the right and left respectively.
The weight of the lever thus operates to throw the pinion toward the adjacent
bevel friction wheel, as shown in the levers 9, at the left side of Fig. 4, or away
from the bevel wheel. if moved reversely, as shown in the nearer lever 10, at the
right hand side of Fig. 4. The drums and m are provided with precisely
similar gearing and levers.
The weighted lever when tipped in one direction thus holds the pinion with a
constant pressure against the bevel wheel, and rotates the connected winding
drum so long as desired; and the tipping of the weighted lever in the opposite
direction serves to stop such winding drum independently of all the others. The
machine is operated as follows.
Reels of the wire to be drawn are suitably supported beyond the ends of the

page_text: machine, four at one end and four at the other, and the wires from one end are
carried through the dies of the upper tier to the four drumis j and k, being
wrapped around all the upper drawing rolls in their passage.
The wires from
the reels at the opposite end of the machine are carried in like manner through
the aics of the lower tier and around the lower drawing rolls to the four drums
and m, all the wires being carried through finishing dies 13 before securing them
to the drums. The driving belt y may be continually operating while the wires
are successively applied, as the drawing of the wire is not effected by the rolls h
until the wire is secured to the proper drum, and the drum set in motion by
means of its own friction wheel. All of the dies may thus be furnished with
wire, and eight wires drawn continuously so long as desired. Any of the drums
may be stopped independently to remove the coil of finished wire, or in case the
wire breaks in the dies, and started again when the wire is newly adjusted.
Troughs 15 are shown in Fig. 1 inserted below the drawing rolls so that a
lubricating liquid may be applied to the rolls as usual; but such troughs are
omitted from the other figures as they form no part of the present invention.
The dies and rolls overhang the rails and e, and are thus in the most convenient
position for inspection by the operator.
It will be observed that although the machine is adapted to draw eight wires
simultaneously, only two wires are carried along each of the rails, as the draw-
ing rolls are adjacent to four rails of the machine. The dies through which the
wires are passed are therefore very accessible, so that the operator can give the
attention that is required and can remove or insert the dies with great facility.
The spindle pulleys require a common alignment to receive the belt which
is applied to them all in common, and by bending the belt back and forth over
the two tiers of pulleys it operates to rotate the rolls of the two tiers in opposite
directions which permits the arrangement of one half the winding drums at one
end of the machine, and one half at the other.
The entire construction and arrangement of the machine thus avoids the arrang-
ing of any or part of the winding drums above the others, as would be required
if the drawing rolls all turned in the same direction.
permit
The adjustable axles of the return pulleys and the guide pulley
those pulleys to be carefully adjusted to carry the return belt under the lower
tier of pulleys and upwardly to the driving pulley ..
It will be observed that the two drawing rolls upon the ends of the spindles
are separated sufficiently to introduce another drawing roll, if desired, in which
case the capacity of the machine would be increased one half, and twelve wind-
ing drums would be required instead of eight. Such additional drums could be
readily mounted and actuated the same as those shown in the drawing where
the margin of each winding drum is arranged tangential to the wire running
from the drawing roll. The machine is therefore not limited to any particular
number of the drawing rolls upon each spindle g, provided the drawing roll
spindles are arranged in two tiers and furnished with belt pulleys having common
alignment, and one side of an endless belt extending back and forth over all the
spindle pulleys to drive the two tiers of spindles in opposite direction. Such
arrangement offers the advantages which I have described, whether the machine
be constructed with eight or more winding drums.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A continuous wire-drawing machine having drawing-roll spindles and dies
arranged in two tiers and the rolls rotated in opposite directions, and having two
sets of winding drums arranged at different levels at opposite ends of the machine
to draw the wire from the two tiers of rolls.
2. A continuous wire-drawing machine having drawing-roll spindles arranged

page_text: in two tiers and provided with belt pulleys having a common alignment, a driv-
ng pulley adjacent to one end of the machine, and an endless belt looped over

over all of the spindle pulleys to drive the two tiers of spindles in opposite
directions.
3. A continuous wire-drawing machine having drawing-roll spindles arranged
in two tiers and provided with belt pulleys having a common alignment, a
return pulley at one end of the machine, a guide pulley at the opposite end,
and an endless belt extended over all of the said pulleys to drive the two tiers
of spindles in opposite directions.
4. A continuous wire-drawing machine having two tiers of spindles with draw-
ing-rolls upon their opposite ends and provided with belt pulleys having a
common alignment, a driving belt extended back and forth over all of the said
pulleys to drive the two tiers of spindles in opposite directions, winding drums
at one end of the machine for the lower tier of drawing rolls, drums at the
opposite end of the machine for the upper tier of drawing rolls, and a separate
clutch for stopping each of such winding drums independently.
