JOHN IMRAY, of Southampton Buildings, in the County of Middlesex. "IM-
PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF WIRE." [A communication
from abroad by Wilhelm Bansen, of Bodenbach, Bohemia, in the Austrian Empire.]
This Invention relates to machinery for the manufacture of wire, such as was
described in the Specification to Lake's Patent, No. 30837, in which the drawing of
the wire was effected by passing it either through a set of three rollers placed at
an angle of 120° to each other, or through a set of four rollers placed at an angle
of 90° to each other, the rollers being so arranged that their axes were all in one
and the same plane, and so formed that at the point where their peripheries touched
each other a small aperture was formed between them having the exact size and
configuration which it was desired to impart to the wire passed through between
them.
One part of the present Invention relates to the arrangement of three rolls in a
group. According to the present improvements two such sets of three rolls aro
arranged in one and the same framing, the one set somewhat in advance of the
other set, and, by preference, in an inverted position, so as to enable the two sets to
be brought as near together as possible, and to alter the positions of the meeting
surfaces of the rollers. Both sets being driven by suitable gearing the wire to be
operated upon is passed through a guide between the first set of rollers, in passing
through which it is subjected to a preparatory drawing, and from which it passes
through a second guide to the second set of rollers, by which the wire is drawn
down to the requisite gauge and bas the necessary polish imparted to it, such polish
11

through a finishing die having the exact required gauge.
Another part of the Invention relates to the four-roller arrangement. According
to the present improvements instead of arranging all four rollers with their axes in
one and the same plane, whereby only the one set is enabled to be driven by
gearing, the one pair of rollers is arranged sufficiently in advance of the other set
that their axles and couplings are clear of each other, so that both sets can be
driven by gearing. As in the three-roller arrangement, the wire is passed first
through a guide to the first pair of rollers, thence through a second guide or die to
the second pair, from which it passes through a finishing die.
By the above arrangement the advantage amongst others is obtained that wire of
rectangular section can be obtained of any desired dimensions by means of one and
the same set of rollers by merely regulating the gauge to which each pair is set,
such regulation being effected by mounting the axles of the rollers in sliding
bearings that are adjustable by means of screws or wedges. Furthermore, by this
arrangement only half the number of rollers previously required are necessary for
rolling cylindrical wire of different gauges, inasmuch as the one pair of rollers is
employed permanently for reducing the wire in one dimension to about the gauge
required, and is then reduced to the exact gauge by the second pair of rollers, the
peripheries of which have semicircular grooves, which, in meeting, form the circular
die of the required gauge, and which consequently alone have to be changed for a
different gauge.

5 PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF WIRE." A communication
from abroad by Wilhelm Bansen, of Bodenbach, Bohemia, in the Austrian Empire.
This Invention relates to machinery for the manufacture of wire, as was described
in the Specification to Lake's Patent, No. 3038, of 1877, in which the drawing of
the wire is effected by passing it either through a set of three rollers placed at an
O angle of 120° to each other, or through a set of four rollers placed at an angle of
90° to each other, the rollers so arranged that their axes are all in one and the same
plane, and so formed that at the point where their peripheries touch each other a
small aperture is formed between them, having the exact size and configuration
which it is desired to impart to the wire passed through between them.
5. . One part of the present Invention relates to the arrangement of three rolls in a
group. According to the present improvement two such sets of three rolls are
arranged in one and the same framing, the one set somewhat in advance of the
other set, and, by preference, in an inverted position, so as to enable the two sets to
be brought as near together as possible, and to alter the positions of the working
O surfaces of the rollers. Both sets being driven by suitable gearing the wire to be
operated upon is passed through a guide between the first set of rollers, in passing
through which it is subjected to a preparatory drawing, and from which it passes
through a second guide to a second set of rollers, by which the wire is drawn down
to the requisite gauge, and has the necessary. polish imparted to it by causing the
5 wire on issuing from the rollers to pass through a finishing die having the exact
required gauge.
Another part of the Invention relates to the four-rollers arrangement. According
to the present improvement instead of arranging all four rollers with their axes in
one and the same plane, whereby only the one set is enabled to be driven by
O gearing, the one pair of rollers is arranged sufficiently in advance of the other set
that their axles and couplings are clear of each other, so that both sets can be
driven by gearing. As in the three-rollers arrangement, the wire is passed first
through a guide to the first pair of rollers, thence through a second guide or die to
the second pair, from which it passes through a finishing die.
By the above arrangement the advantage amongst others is obtained that wire of
rectangular section can be produced of any desired dimensions by means of one and
the same set of rollers by merely regulating the gauge to which each pair is set,
such regulation being effected by mounting the axles of the rollers in sliding
bearings that are adjustable by means of screws or wedges. Furthermore, by
O this arrangement only half the number of rollers previously required are necessary
for rolling cylindrical wire of different gauges, inasmuch as the one pair of rollers is
employed permanently for reducing the wire in one dimension to about the gauge
required, and the said wire is then reduced to the exact gauge by the second pair of
rollers, the peripheries of which have semicircular grooves which, in meeting, form
the circular die of the required gauge, and which consequently alone have to be
changed for a different gauge.

With reference to the arrangement of three rolls in a group, Fig. 1* of the
accompanying Drawings represents the vertical transverse section taken in the line
W, W, of Fig. 2* through the front set of three rolls.
Fig. 2 is a vertical longitudinal section taken in the line U, U, of Figs. 1*
and 3*.
Fig. 3 represents another vertical transverse section taken in the line W 1, W 1, of
Fig. 2 through the hinder set of three rolls and Fic. 4* is a plan section taken

page_text: In these Figures, A1, A2, A3, represent the rollers of the one set, and
A 4, A5, A6, the rollers of the other set. a, a, represent the sliding bearings of
the axles of the rollers, and these bearings are adjustable by means of screws C, C,
excepting the bearings of the roller A 6, which are adjustable by wedges C 1, C1 ; b
are regulating screws for the endwise adjustment of the bearings a. D is the guide a
between the first set of rollers A 1, A 2, A 3, through which the wire to be operated
upon is passed, and from which it passes through the second guide D to the second
sot of rollers A4, A5, A6, thence being caused on issuing from the rollers to pass
through a finishing die F having the exact required gauge.
According to the present improvement two such sets of three rolls are arranged 1
in one and the same framing, the one set A1, A2, A3, somewhat in advance of the
other set A4, A5, A6, and, by preference, in an inverted position, so as to enable
the two sets to be brought as near together as possible, and to alter the positions of
the working surfaces of the rollers. Both sets being driven by suitable gearing the
vire to be operated upon is passed through a guide D between the first set of 1
rollers A1, A2, A3, in passing through which it is subjected to a preparatory
drawing, and from which it passes through a second guide D1 to the second set of
rollers A4, A5, A6, by which the wire is drawn down to the requisite gauge and
has the necessary polish imparted to it, such polish being finally perfected by
causing the wire on 'issuing from the rollers to pass through a finishing die F'having ?
the exact required gauge.
•
With reference to the four-rollers arrangement Fig. 1 of the accompanying
Drawings represents the vertical longitudinal section taken on the line Y, Y, of
Fig. 2, and shows also a section of the gearing of the axles B4, B4.
Fig. 2 is a vertical transverse section taken on the line X, X, of Fig. 1.
Fig. 3 is a sectional plan view taken in the line Z, Z, of Figure 1; and the Figa.
4, 5, 6, and 7 show some parts in detail.
The two vertical rollers A1, A2, are coupled to the axles B2 by means of
couplings B1, also the horizontal rollers A 3, À 4, are coupled to the axles B4 by
means of coupling C 3. The adjustment of the bearings a, a, of the rollers is effected 3
by screws C; the bearings of the roller A 2 however are adjusted by means of
wedges C1. bare regulating screws for the endwise adjustment of the bearings a
of the rollers. D is the guide through which the wire is passed to the first pair of
rollers A1, A2, thence passing through a second die or guide D1 to the second
pair of rollers A 3, A4, from which it passes through a finishing die F.
3
For rolling cylindrical wire the form of the rollers A 1, A 2, is the same as for
rolling wire of rectangular section, the rollers having flattened edges; the rollers
A3, A4, however are provided with semicircular grooves in the centro of the
flattened edges, as shewn in Fig. 4, these rollers A 3, A4, being so mounted by
means of the screws c'that their peripheries touch each other, and in meeting form 4
the circular groove die of the required gauge. The finishing die F is provided with
the same gauge as the circular aperture formed between the rollers A. 3, A. 4.
The second guide D1 is mounted, as shewn in Figs. 5, 6, and 7 of the accom-
panying Drawings, in a recess of the framing between the four rollers, and may be
inserted from above into that recess, Fig. 5 showing a top view of the said 4
guide D1; Fig. 6, a longitudinal section of the same; and Fig 7, a front elevation
of the said guide.
According to the present improvement instead of arranging all four rollers with
their axes in one and the same plane, whereby only the one set is enabled to be
driven by gearing, the one pair of rollers A 1, A 2, is arranged sufficiently in advance 5
of the other set A 3, A 4, that their axles and couplings are clear of each other, so
that both sets can be driven by gearing as in the three-rollers arrangement, the
wire is. passed first through a guide D to the first pair of rollers A 1, A 2, thence
through a second guide or die D 1 to the second pair A 3, A 4, from which it passes
through a finishing die F.
By the above arrangement the advantage, amongst others, is obtained that wire
of rectangular section can be obtained of any desired dimensions by incans of one

page_text: and the same set of rollers by merely regulating the gauge to which each pair is set,
such regulation being effected by mounting the axles of the rollers in sliding
bearings a, that are adjustable by means of screws C or wedges C 1. Furthermore,
by this arrangement only half the number of rollers previously required are necessary
for rolling cylindrical wire of different gauges, inasmuch as the one pair of rollers
A 1, A 2, is employed permanently for reducing the wire in one dimension to about
the gauge required, and the said wire is then reduced to the exact gauge by the
second pair of rollers A3, A4, the peripheries of which have semicircular grooves,
which in meeting form the circular die of the required gauge, and which con-
sequently alone have to be changed for a different gauge.
Having thus described the nature of the said Invention, and explained the
manner of carrying the same into effect, as communicated to me by my foreign
correspondent, I wish it to be understood that I claim,―
1. The construction and arrangement of a wire-rolling train with six disc-shaped
rollers, as above described.
2. The combination with two sets of three rolls arranged adjustably in one and
the same framing of a second guide D 1 arranged between them, the finishing
die F, and the first guide D, for the purpose of drawing and rolling of circular
and rectangular section, substantially as shewn in Fig. 2* of the accompanying
Drawings.
3. The construction and arrangement of a wire-rolling train with four disc-
shaped rollers, as above described.
4. The combination with two vertical rollers A1, A2, and two horizontal
rollers A 3, A4, adjustably mounted in one and the same framing, the one pair of
rollers being arranged in a certain advance of the other set, of a guide D 1, arranged
between the two pairs of rollers, a finishing die F behind the last pair of rollers and
guide D, for the purpose of drawing and rolling wire of any section and gauge, as
shewn in Fig. 2 of the accompanying Drawings.
In witness whereof, I, the said John Imray, have hereunto set my hand and
seal, this Eighteenth day of November, in the year of our Lord One thousand
eight hundred and seventy-eight.
