Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
WIRE." [A communication from abroad by William Bansen, of Bodenbach on the
Elbe, Austria, Manufacturer of Wire.]
These improvements relate to the manufacture of wire.
Hitherto in the manufacture of wire of larger diameter, pairs of rollers having
their axes parallel to each other have been used, and in the manufacture of wire of
smaller diameter, the wire has been drawn through a steel draw plate.
According to this Invention, a set of three grooved rollers, arranged at an angle
of 120 degrees to each other, or, for thicker wire, a set of four grooved rollers
arranged at an angle of 90 degrees to each other, is used, and in combination with
such a set of rollers, a die is arranged in such a manner that the wire, after passing
through the said rollers, is forced through the said die. The said rollers are there-
fore so arranged that their edges run in contact with each other; and when a set
of three rollers is used, the groove in each roller forms one-third of the entire
circumference of the space through which the wire is rolled, or one-fourth when a
set of four rollers is used, as above described.
The three or four rollers of each set may be geared together in any suitable
manner so as to run with equal speed.
Amongst other advantages obtained by these improvements, wire of smaller
diameter may be rolled than hitherto usual, because the rollers have the tendency to
force the wire towards the centre of the space formed by their grooves, and the
texture and strength of the wire are less subject to injury.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
WIRE." A communication from abroad by William Bansen, of Bodenbach on the
Elbe, Austria, Manufacturer of Wire.
This Invention relates to improvements in the manufacture of wire, as herein-
after set forth.
Hitherto in the manufacture of wire of large gauge, pairs of rollers having their
axes parallel to each other and with some of their grooves of oval and square section
have been used, and in the manufacture of wire of smaller gauge, the wire has been
drawn through a steel draw plate.
According to the present Invention, a set of three grooved rollers, arranged at
angles of 120 degrees to each other, is used for the manufacture of wire of small
gauge, and a set of four grooved rollers, arranged at an angle of 90 degrees to each
other, for the manufacture of wire of larger gauge; and the said rollers are combined
with a die in such a manner that the wire, after passing between the rollers, is
forced through the said die.
Amongst other advantages obtained by this Invention are the following, that is
to say-Wire of a smaller gauge than heretofore can be rolled because the rollers
have the tendency to force the wire to the centre of the space formed by their
grooves; and further, the texture and strength of the wire is less injuriously
affected.
In the accompanying Drawing, Figure 1 is a section on the line A, B, Figure 3,
shewing a set of three rollers arranged at angles of 120 degrees to each other;
Figure 2 is a section on the line E, F, Figure 1; and, Figure 3 is a section on the
line C, D, Figure 1.
a is the guide box for leading the wire to the rollers; b is the die fixed in the
box c, through which die the wire proceeding from the rollers is forced by the same.
The die 6 serves to remove any irregularity which may have been formed on the
wire by the rollers, and therefore performs the service of the draw plate used in
some wire works.
The operation of this Invention is as follows:-Wire of, for instance, eight thirty-
seconds (8/32nda) inch gauge is passed through the guideway a, Figure 3, into a
space of, for instance, seven thirty-seconds (7/32nds) inch gauge formed by the grooves
of the set of three or four rollers; having passed these rollers, it is forced through
the die plate b, having also a perforation of seven thirty-seconds (7/32nds) inch.
The wire proceeding hence is then passed through another similar set of rollers and
treated in the same manner. This operation is repeated until the wire has been
reduced to the required gauge.
The rollers are driven by any suitable motive power applied to the end d or d¹
of one of the rollers. In this manner wire down to one-twelfth inch gauge may be.
rolled.
Without departing from the nature of this Invention, an arrangement of four
grooved rollers, arranged at angles of ninety degrees to each other, may, as above
specified, be used instead of a set of three rollers at angles of 120 degrees.
Having thus fully described the said Invention; as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,—
First. The construction and arrangement of machinery for the manufacture of
wire, as above described and shown in the accompanying Drawing.
Second. A device for rolling wire, consisting of three grooved rollers arranged
at angles of 120 degrees to each other; in combination with a perforated die through
which the wire is forced by the said rollers, as above described;

page_text: Third. A device for rolling wire, consisting of four grooved rollers arranged at
angles of 90 degrees to each other, in combination with a perforated die through
which the wire is forced by the said rollers, as above described.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Sixth day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
