Wire-drawing and Spooling Machine and Method of Spooling and
Annealing the Wire.
I, CHAUNCEY CLARK BALDWIN, Engineer, of No. 125, De Hart Place, in the City
of Elizabeth, in the County of Union, in the State of New Jersey, United States
of America, 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 in which
the wire is drawn successively through a series of wire-dies to continuously reduce
the wire, and the object of the present invention is to furnish a machine in which
the wire may not only be finished in coils upon a finishing drum, but may, when
desired, be wound upon spools for sale, and also annealed thereon.
The same machine is thus adapted to furnish the wire in coils or in spools. The
spools are made of steel, and the wire is annealed by heating the spool with its
contents in an annealing pot, and my method of furnishing spools of annealed
wire includes the reduction of the wire in a continuous wire-drawing machine,
the drawing of the wire from the last die by a finishing drum, the extension of
the wire from the finishing drum to a spooling appliance upon the wire-drawing
machine, and the heating of the wire-laden spools in an annealing pot.
The spooling appliance has a rotating spindle traversed longitudinally at the
side of the finishing drum so that the wire when wound a few times around the
finishing drum, may be extended drectly to the spool and distributed between the
end flanges of the spool by the traverse motion of the spindle. These improvments
are especially desirable for spooling small wire below two millimetres in diameter.
In the drawing, Fig. 1 is a plan, and Fig. 2 a side elevation of a continuous
wire-drawing machine provided with the spooling appliance. Fig. 3 is a front
view of the machine; Fig. 4 is a side view of one of the steel spools; and Figs. 5
and 6 a side and edge view of one of the spool flanges; Figs. 7 and 8 are side and
end views of the spool-hub; Fig. 9 is an elevation of the traverse-spindle and its
driving sleeve; and Fig. 10 is a section of the annealing pot with spools packel
therein.
The machine illustrated has two drawing-rolls A, A¹, a series of wire-dies B,
a finishing-die B', a finishing drum C, and a frame D for supporting all the parts.
The drums A, A¹, have shafts a, a¹, connected by gears G and driven by pullies G¹.
The finishing drum C is connected with the shaft a¹ by gears E and belt F.
To form the wire in coils upon the drum, the wire w is extended from a reel W
successively through the several dies B and around the rolls A, A', and finally
through the finishing die B₁ to the drum C upon which it may be made into coils
by clamping the end of the wire thereto. For spooling the wire, a traverse-
spindle H is extended at the side of the drum C to receive upon its end the spool S.
Bracket-bearings I sustain the spindle, and a sleeve J is fitted between the bear-
ings and driven by cog-wheels K, the wheels receiving motion from a shaft
which is connected with the shaft a¹ by grooved pullies and a belt P.

page_text: A cam L is provided to traverse the spindle H and is driven by worm wheel M
and a worm m upon the shaft k. The sleeve has a key fitted to slide in a groove J
in the spindle, and the cam-slide H is swiveled to the spindle H at ', as shown
in Fig. 9. The spindle H traverses the spool at the side of the drum in a suitable
position, as shown in Fig. 1, to lead the wire back and forth upon the spool as
it runs from the drum, and the pullies are proportioned to draw the wire from the
drum at a suitable speed when the spool is empty.
し
As the diameter of the spool increases by the accumulation of the wire, the belt 71
slips upon the pullies and form a frictional driver or connection between the
drawing-roll A and the spool. The spooling appliance is not subjected to any
of the strain of drawing the wire, as the final strain of drawing the wire is entirely
confined to the finishing drum by coiling the wire a few turns around the same
before extending it to the spool. The steel spools are made, as shown in Figs. 5
to S, with a. tubular hub s having integral studs upon the ends, and flanges s
having holes to receive the studs which are riveted therein. The hub is made
of metal tubing milled at the ends to form the studs, and the flanges are of sheet
metal stamped to the desired form and provided with central hole to hit upon the
traverse-spindle H. The spindle is formed with collar h having a driving-stud i
to fit a hole in the spool flange, and the spools are held upon the spindle by a
nut H.
It will be observed that when winding the wire upon spools, the end of the wire is
not fastened to the finishing drum C, but is extended therefrom to the spool, and
engaged with the hub or flange of the spool, so that the wire may be drawn con-
tinuously from the drum and wound up by the spool.
In Fig. 4, a hole o is shown in the hub of the spool to engage the end of the
wire for winding the first layer upon the spool. When the spool is filled the wire
is cut, and one end tied or looped upon the exterior of the spool, and the spool then
replaced upon the spindle H by an empty spool, to which the other end of the wire
is again engaged. It will be observed in Fig. 4, that when the spool is removed
from the spindle its heads are free from any projections, and a series of the filled
spools may thus be packed closely together in an annealing pot P, as shown in the
section in Fig. 10, where four of the spools are shown surrounded within the pot by
sand p. The pot is shown with a detachable cover N secured by a yoke N¹ and
wedge N2, as is common in such constructions, and the wire is annealed by heating
the whole in a furnace, to a suitable temperature, and cooling off the pot and its
contents before exposing the spools of wire to the atmosphere. The annealed wire
is thus protected from oxidation and requires no repolishing to fit it for any use
where annealed wire is required. The novelty in my method of producing the
annealed wire does not consist in the mere annealing, but in the continuous opera-
tion of drawing, spooling, and annealing the wire so that it is furnished for sale
with the least possible expense.
My method of drawing, spooling, and annealing the wire in a continuous opera-
tion obviates the almost universal practice of annealing the wire in loose coils,
so that it requires no pickling and spooling in separate operations, after the com-
pletion of wire-drawing.
The invention is illustrated in a suitable form for use with a continuous wire-
drawing machine having the wire wound repeatedly upon the same drums A, A¹,
but the spooling appliance may be applied to any form of continuous wire-drawing
machine, so as to reduce the wire and spool it in a single operation.
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 wire-drawing apparatus having a series of dies and drawing-rolls suitable
for continuous wire-drawing, and having a finishing drum to draw the wire through
the last die and provided with a spooling appliance having a spool to receive the
wire directly from the finishing drum whereby the finished wire may either be

page_text: coiled upon the drum or delivered from the machine upon spools, substantially as
herein set forth.
2. A continuous wire-drawing machine having a finishing drum to draw the
wire from the last die, and provided with a rotating spindle traversed longitudinally
at the side of said drum and carrying a spool to wind the wire and a finishing drum
having the finished wire wound a few times around the same and secured to the
spool to be wound thereon.
3. A continuous wire-drawing machine having a spooling appliance for support-
ing and traversing a spool, a finishing drum with the finished wire wound a few
times around said drum and extended to the spool, and a friction driver for rotating
the spool at a suitable speed to wind the wire when first applied to the spool, and
adapted to slip as the spool is gradually filled.
4. A wire-winding spool comprising the metal tube having integral studs upon
the ends and metal flanges having holes to receive the studs.
5. The method of preparing annealed wire for the market in a continuous opera-
tion, which consists in reducing the wire in a continuous wire-drawing machine.
winding it a few turns upon a finishing drum, drawing it thence and spooling
it upon a metallic spool, and finally, annealing the wire upon the spools in a recep-
tacle adapted to exclude the air from the wire, to preserve its polish, substantially
as herein set forth.
