Year: 1878

Patent Solicitors, at Frankfort on the Main, in the Empire of Germany, for the
Invention of IMPROVEMENTS IN ROLLS FOR ROLLING WIRE." A commu-
nication from Reiner Daelen, of Düsseldorf, in the Empire of Germany.
Sealed the 27th May 1879, and dated the 30th November 1878.
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office
of the Commissioners of Patents on the 30th November 1878.
FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main, in the Empire of Germany. "IMPROVEMENTS IN ROLLS
FOR ROLLING WIRE." [A communication from Reiner Daelen, of Düsseldorf, in
the Empire of Germany.]
This Invention relates to improvements in rolls for rolling wire whereby a set or
series of wire rolls is caused to work direct from each other without the use of
conical wheels, and the rolling of the wire is effected without hand labour.
The said Invention consists of a series of pairs of rolls placed one behind the other
horizontally and vertically. I provide toothed wheels by which the pairs of hori-
zontal rolls are worked, the pairs of vertical rolls being driven direct from the former
by means of an endless screw. The reduction of the calibre of all the rolls is equal'
from No. 1 to 10 in the proportion of 8 to 5. All the calibres are of trapezian
form; then follows an oval, and then finally the round and finished wire groove.
The speed at which the rolls run is made to correspond to the stretching of the
bar of metal as it grows longer, the last pair of rolls having to run considerably
faster than the first pair, the first pair making about ten and the last about one
thousand revolutions a minute.

the said Frank Wirth in the Great Seal Patent Office on the 30th May
1879.
FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at
Frankfort-on-the-Main, in the Empire of Germany. "IMPROVEMENTS IN ROLLS
FOR ROLLING WIRE." A communication from Reiner Daelen, of Düsseldorff, in
the Empire of Germany.
This Invention relates to improvements in rolls for rolling wire whereby a set or
series of wire rolls is caused to work direct from each other without the use of bevel
wheels, and the rolling of the wire is effected without hand labour.
The said Invention comprises a series of pairs of rolls placed one behind the
other, and arranged horizontally and vertically, as shewn in Figures 1 and 2,
which represent a vertical longitudinal section of a series of rolls arranged
according to my Invention, and a plan or top view partly in section of the same.
In these Figures are shewn the toothed wheels by which the six pairs of horizontal
rolls are worked, the six pairs of vertical rolls being driven direct from the former
by means of endless screws.
The calibre of the rolls as formerly used is shewn in Figure 3 of the Drawing, and
the calibre of the rolls constructed according to this Invention is illustrated in
Figure 4.
The reduction of the calibres is equal throughout the series of rolls from No. 1
to 10 in the proportion of 8 to 5, all of these calibres being of trapezian form ; then
follows an oval, and then, finally, the round and finished wire groove.
The speed at which the rolls run is made to correspond to the stretching of the
bar of metal as it becomes elongated, the last pair of rollers having to run consider-
ably faster than the first pair, the first pair making about ten and the last pair
about one thousand revolutions per minute.
In combination with my improved arrangement of rolls, as above described, I
employ a wire winding or collecting apparatus, as shewn in Figures 1 and 2. This
apparatus consists of a plate A surrounded by a rim B, the plate A being attached
to the vertical journal a which receives motion from the wire rolls through suitable
gearing. The rim B does not move with the plate A and is capable of being lowered
by means of the lever C. As long as the machine is in motion the said rim is held
in its elevated position, as shewn in Figure 1.
As the wire comes from the mill it shoots or passes to the plate A and against
the rim B. The plate A in revolving carries the wire around until the piece is
finished, and the rim B is then lowered and the coil lifted from the said plate.
Having thus fully described the said Invention, and the manner of performing
the same, I wish it understood that I claim,-
First. The method of running a set or series of wire-rolls direct from each other
without the use of bevel wheels, substantially as shewn and described.
Second. The trapezian shaped groove for wire rolls, as shewn and described.
Third. The mechanism for rolling wire without hand labor, as above set forth.
Fourth. The combination with the said mechanism of the improved winding or
collecting apparatus, substantially as shewn and described.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand and
seal, this Twenty sixth day of May, in the year of our Lord One thousand
eight hundred and seventy-nine.
