page_text: vertical rolls can be placed on one side of and between the horizontal rolis; and
also the automatic guide-way can be carried between the spindles of the coupling-
gear which allow ample space for that purpose. The driving of the horizontal
rolls can then be effected, as usual, by means of a double spur gear train with
coupling-spindles and sleeve-couplings; the driving-wheel being secured to the first
driven shaft, and gearing with spur pinion on the shaft of the lower-roller, which
pinion in its turn gears with and drives a similar spur-pinion fixed on the shaft of
the upper roller, while the vertical rolls are driven by a shaft arranged, as in
Type I, ou one side of the horizontal rolls. The bevel gear may in this case be
either single or double, according as the shaft is driven by double or single
spur-gearing.
An increasing circumferential velocity of the horizontal rolls is in this case more
easily obtained by enlarging the diameter of the pairs of rolls following in
succession, in due proportion, inasmuch as the coupling spindles, which are in
consequence brought to assume an inclined position, are of greater length than
they would otherwise be, and the inclination can be divided on both.
TYPE IV.
In order to dispense with guide-ways for the oval rolls, two sets of rolls of
the Type II may be arranged parallel, side by side, in such manner that they
alternate and so that first a vertical oval wire-rolling frame comes in front of
square wire rolling frame, and then vice versa; whereby also the length of the
rolling train is reduced to a half.
In this case the entrance-guides for the oval rods may be made narrower, as the
introduction of the oval rods requires the command of greater power.
Further, both lines of rolls may be set so far apart that there may be sufficient
room for the formation of a coil; and consequently the checking and adjustment
of the rolls, and the gauging, are free from all difficulty.
Similarly, the construction of a guide-apparatus for the oval wire, of such kind
that it will automatically open to permit the passage of a kink or coil and thereafter
close automatically, ceases to offer any difficulty.
By means of the before described arrangements of housing frames in wire-rolling
mills the following advantages are gained;-
1. A material saving in wages, inasmuch as, for the surface of the finishing stage,
only one overseer is required.
2. A high productive power, determined, on the one hand by the fact that
automatic guides have come into use with all housing frames for wire-rolling mills,
und on the other by the increased roller-speed; and moreover, it being no longer
limited by the fact that the capacity of the workers cannot be extended beyond
certain limits.
3. Easily realised increase of speed in the succession of the rolling frames, by
corresponding selection of the driving gear as well as of the spur and bevel gear.
4. Diminished liability to variations within certain limits in the diameter of the
rolls in one and the same frame, as well as in the gauging owing to conditional
changes from wear; inasmuch as any increase or diminution in the kinks or coils
due to specific causes remains without influence on the execution of the rolling.
5. The speed of the driving motor may be reduced, that is to say, the speed
remaining the same, a greater circumferential velocity is attained by the rolls.
6. Owing to the increased speed of the rolling the temperature of the finished
products is higher, permitting an increase in the weight of output, as the temperature
and therefore the differences of sectional area of the rod-ends can be brought down
to a smaller proportion.
Further it is not difficult to construct a rolling train of this kind adapted for
the rolling of fine iron of all kinds; because in this case the vertical rolls would
simply be dispensed with (Type IV) and in lieu of the square-wire rolls, others of
the required form or profile would have to be substituted.

page_text: Lastly, it is easy to fit up any existing train of rolls according to this system.
because all the rolls and one half of the ordinary housing frames can be utilised
for the purpose.

Improvements in Wire-rolling Apparatus.
I, DESIDERIUS TURK, Manager of Ironworks, Dimlach, near Kapfenberg,
Steiermark, in the Empire of Austria, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates, to a new arrangement of housing frames in a wire-
rolling mill, intended to obviate the defects of the existing methods. The chief
disadvantages attendant upon wire-rolling mills as at present constructed are :-
1. When the housing frames are placed side by side, it is necessary to provide
men and boys or special devices to straighten out the kinks which are constantly
being formed, and it becomes difficult to obtain against the finishing frame such an
increased speed as may be desired.
2. When the housing frames are placed one in front of the other, the operations
of checking and adjusting the diameter of the rolls, and of gauging, are laborious,
difficult and costly, and there is scarcely room for the kinks and coils to be properly
dealt with.
3. In all wire-rolling mills, for the direct service of which workmen are
indispensable, the speed of rolling is more limited and variable, whereby production
is correspondingly diminished.
I overcome all these disadvantages by my improved arrangement of housing
frames for wire-rolling mills, as shown in the accompanying drawings and of which
the essential features are as follows:-
I erect housing frames for vertical oval-wire rolls O between housing frames for
horizontal square-wire rolls A, in such manner that the rolled material may be led
from one frame to the other by means of the (well known) automatic guide-ways U.
In the accompanying drawings I have illustrated my improved wire-rolling
apparatus:
Figure 1 is a view of the apparatus partly in front elevation and partly in
longitudinal vertical section ;
Figure 2 is a plan of the same; and
Figure 3 is a section on the line -x of Figures 1 and 2.
The driving of the vertical rolls O is effected by means of the driving shafts to
and warranged under the rolls, and provided with bevel-wheels k keyed on the
shafts which gear with the corresponding bevel-wheels keyed on the lower
gudgeon of one of each pair of said vertical rolls.
The driving of the horizontal rolls A is effected by an ordinary spur-gear
train froin the shafts w w¹.
Either of these two shafts may be the first-motion shaft, the other being driven
therefrom by suitable spur-gear.
One advantage of this arrangement-an advantage not to be under-rated—is the
cheap and compact nature of the mills.
Another important advantage of my invention, as compared with similar wire
rolling-mills working with vertical rolls, lies in the fact that, on the one hand in
the fornier the oval-calibre appears transposed in the vertical rolls, and on the other
hand, the vertical rolls are arranged parallel to the rolling-train, and their driving

page_text: by bevel-gear is obtained in a much simpler and more reliable manner; while,
finally, no attendants whatever are necessary to the working of the rolling train.
As compared also with other well-known arrangements, my new rolling mills
differ essentially, in the fact that with them not more than two sets of rolls, at the
most are placed one behind the other, whereby is avoided the great disadvantage
of the excessively troublesome and costly charges for maintenance of the works.
The cost of maintenance of the rolls under other existing systems, wherein the
rolling-frames are placed one behind another, according to this invention is
materially diminished, owing to the fact that on account of the reduced bending
resistance, between the rolling-frames, met with by the oval rods in their passage
from one to the other, it is easy to give them a change of direction either
horizontally or even in an inclined direction.
By means of the arrangements of housing frames in wire-rolling mills shown in
the accompanying drawings, the following advantages are gained :-
1. A material saving in wages, inasmuch as for the service of the finishing stage,
only one overseer is required.
2. A. high productive power, determined, on the one hand, by the fact that
automatic guides have come into use with all housing frames for wire-rolling mills,
and on the other by the increased roller-speed; and moreover, it being no longer
affected by the fact that the capacity of the workers cannot be extended beyond
certain limits.
3. Easily realized increase of speed in the separate rolling frames as required.
4. Better utilization of the rolls, inasmuch as when, by their having been turned
down, they have become weaker, the rolls may, without hesitation be used for
rolling wires of coarser calibre, for which the speed can be suitably selected, at
pleasure, in accordance with the changes of gearing.
5. Diminished liability to variations, within certain limits, in the diameter of the
rolls in one and the same frame, as well as in the gauging owing to conditional
changes from wear; inasmuch as any increase or diminution in the kinks or coils
due to specific causes will not affect the passage of the rod between the rolls.
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 claim is :-
1. A wire-rolling mill with vertical oval-wire rolls such as O and horizontal
square-wire rolls A which work the wire alternately and are so arranged one behind
the other that the wire by means of automatic guideways such as U is wrought
simultaneously by two rolling-traius lying one immediately behind the other.
2. In a wire-rolling plant the combination with oval and square wire rolls
arranged in one line of other square and oval wire rolls arranged in a parallel line
the oval wire rolls of one line being opposite the square wire rolls of the other
line and vice versa substantially as described and illustrated in the accompanying
drawings.
3. In a wire-rolling plant the combination with oval and square-wire rolls
arranged in two parallel lines the oval wire rolls of one line being opposite the
square-wire rolls of the other line of guide ways such as U substantially as
described and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete wire-
rolling apparatus operating substantially as described and illustrated in the
accompanying drawings.
