The manufacture of wire as heretofore practised necessitates the repeated passage
of the metal first through rolls for the purpose of reducing and drawing down the
ingot, and afterwards through draw plates, in order to further reduce the wire
obtained by the rolling process to the required diameter. The present Invention
has for its object an improved arrangement of rotating ingot mould, whereby it is
rendered possible to run out the metal directly in the form of wire of the required
diameter or nearly so.-A rotating ingot mould adapted for carrying out the
present Invention may be arranged as next hereinafter described by way of
example. This apparatus is composed of a vertical shaft supported at its lower
extremity in a footstep bearing-This shaft carries a cast iron plate, provided at its
outer edge with an annular channel. This channel is closed in or covered by a ring
or annular cover forming the mould proper-For this purpose the said ring is
provided with a groove of suitable form, for the reception of the molten metal.―
This metal is contained in a pocket or ladle, supported by an iron ring swivelling
on trunnions or centres, and carrying a rod or arm, to the upper extremity of

a pulley or drum on the vertical shaft.-The lower part of this shaft is provided
with a bevel wheel, gearing with a corresponding wheel on a horizontal shaft.-
This horizontal shaft is provided with fast and loose driving pulleys.
The annular channel is supplied with water by a pipe; this water passes through
a stop-cock, traverses footstep bearing and is conducted along the centre of the
vertical shaft, whence it flows through a radial pipe to the channel. The water
escapes from the channel through another radial pipe, descends in the centre of the
hollow vertical shaft, and is discharged through suitable channels formed in the
footstep bearing, into a pipe provided for its reception.-The metal run into the
mould or annular groove herein before described is cooled by the circulation of
the water, and solidifies.-The wire thus produced is lifted by a finger or point,
and conducted away from the mould as fast as it solidifies.-The rotation of the
shaft causes the cord attached to the arm on the ring supporting the ladle to be
wound upon the drum or pulley, thus tilting the ladle and causing it to deliver
the molten metal in a regular and constant stream.
The periphery of the drum or pulley is made of special form, determined by
experience, with a view of causing the metal to flow with great regularity.-The
framework of the apparatus is made of cast iron, and is provided with a trough or
gutter for the reception of the water in case of leakage.-The wire obtained by
means of this apparatus simply requires to be passed once or twice through a draw
plate. By suitably modifying the form of the revolving mould, the wires may be
made with enlargements, swellings, or other appendages of any suitable material.

(a communication to me from abroad by Eugené Isidore Levavasseur of Paris in
the Republic of France, Manufacturer)
The manufacture of wire as heretofore practised necessitates the repeated passage
of the metal first through rolls for the purpose of reducing and drawing down the
ingot, and afterwards through drawplates in order to further reduce the wire
obtained by the rolling process tothe required diameter-The present Invention
has for its object an improved arrangement of rotating ingot mould whereby it is
rendered possible to run out the metal directly in the form of wire of the required
diameter or nearly so.
In the annexed drawing, Fig. 1 is an elevation of the improved rotary mould.
Fig. 2, plan. Fig 3 Section drawn to larger scale of ingot mould
The apparatus is composed of a vertical shaft A, supported at its lower extremity
in a footstep bearing B-This shaft carries a cast iron plate C, provided at its outer
edge with an annular channel D.-This channel is closed in or covered by a ring or
annular cover E, forming the mould proper.-For this purpose, the said ring is
provided with a groove E of suitable form for the reception of the molten metal-This
inetal is contained in a pocket or ladle G, supported by an iron ring T, swivelling on
trunnions or centres t, and carrying a rod or arm H, to the upper extremity of which is
attached a cord I, which is connected to and capable of being wound upon a pulley or
drum J on the vertical shaft.-The lower part of this shaft is provided with a bevel
wheel K, gearing with a corresponding wheel K' on a horizontal shaft L. This
horizontal shaft is provided with fast and loose driving pulleys M. The annular
channel D is supplied with water by a pipe a, this water passes through a stop
cock b, traverses footstep bearing B, and is conducted along the centre of the
vertical shaft A, whence it flows through a radial pipe c to the channel D―The
water escapes from the channel D through another radial pipe d, descends in the
centre of the hollow vertical shaft, and is discharged through suitable channels
formed in the footstep bearing into a pipe e, provided for its reception.-The metal
run into the mould or annular groove herein before described is cooled by the
circulation of the water, and solidifies.-The wire thus produced is lifted at O by a
finger or point f, and conducted away from the mould as fast as it solidifies The
rotation of the shaft causes the cord attached to the arm on the ring supporting
the ladle to be wound upon the drum or pulley, thus tilting the ladle, and causing
it to deliver the molten metal in a regular and constant stream. The periphery of
the drum or pulley J is made of special form, determined by experience, with a
view to causing the metal to flow with great regularity.-The framework R of the
apparatus is made of cast iron, and is provided with a trough or gutter for the
reception of the water in case of leakage.-The wire obtained by means of this
apparatus simply requires to be passed once or twice through a draw plate.-By
suitably modifying the form of the revolving mould, the wires may be made with
enlargements, swellings, or other appendages of any suitable material.
The ring of wire, when it has been cast in the circular channel, would rest upon
the table after having been expelled from the channel, the rotary motion of the
table would then cause it to rub, and thus give rise to a resistance prejudicial to
proper working. Moreover, the metal being still hot, would be liable to be crowded

page_text: up in the preceding coils, and to get out of shape. In order to obviate this
inconvenience, eight pincers or grippers are employed radiating from the centre to
the circumference, for the purpose of holding up the coils of wire, as the latter are
cast. Upon the table C are permanently fixed eight supports N, upon which
oscillate grippers P. These grippers present a small concave recess at their points,
which prevents the wire from escaping-To a support Q is fixed a cam g, which
lowers. the grippers when they pass beneath, and enables them to take up the wire
in succession as they pass under the cam.-The action of the grippers is regulated
by an inclined surface h, which prepares them for the reception of fresh coils.-The
advantage attending the super position of the coils of wire as fast as they were cast
suggested the idea of employing when necessary in place of the ordinary table or
plain ring a channel formed on the upper side of a helix in the form of a square
threaded screw. This modification is illustrated in Fig. 4 of the accompanying
drawing Upon a hollow cylinder V is formed a thread k in the form of a helix,
and a groove or channel is hollowed out of the upper side of this thread.-A.
shaft X permanently fixed in the hollow cylinder imparts to the latter a rotary
motion, and with the aid of four rollers 7 fixed to the frame, an ascending motion
also. This shaft X is squared at the lower end, to enable the rotary motion to be
imparted to it by means of bevel wheels m. n., and to admit of this motion being
converted into a rising motion. By thus employing the helix and rollers, the
cylinder is guided by the extremity of the axis of the rollers 7.-The crucible o
operated automatically by the driving shaft L, is permanently fixed to the
frame Y. The working of this machine will be readily understood. When the
casting is terminated, it suffices to throw it out of gear, to take up the wire that has
been cast, then to set back the machine to the position for starting, and re-commence
operations.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim :-
(1st.) Casting wire direct to its proper thickness in moulds cooled by the
circulation of cold water
(2nd) The arrangement of apparatus herein before described for the continuous
manufacture of such wire by means of a rotating mould.
(3rd) The special arrangement of the rotating mould provided with at able
furnished with radiating grippers or supports, which hold up the coils of wire as
the latter are cast.
(4th) The modification illustrated in Fig. 4, consisting of a cylinder presenting a
channel hollowed out in the upper side of a helical thread on the circumference of
the cylinder. all substantially as herein before set forth and described
In Witness whereof I the said Thomas Morgan have hereunto set my hand
and seal this seventeenth day of January in the year of our Lord one
thousand eight hundred and eighty three.
