AUGUST WILKE, of Braunschweig, Germany. " IMPROVEMENTS IN METAL ROLLING
MACHINES."
The construction consists, as represented in the annexed Drawings, of 7 wrought-
iron rollers, 105 millim. diameter, and 1 meter 5 long, and are intended for sheet
ion from 1 to 4 millim. thick; for thicker sheet iron the rollers will have to be of
a larger diameter.
The principle driving roller 1A is put into motion by means of the counter
shafts I and II.; this former drives the roller 4 A at the extremity J, sketch No. 2;
the roller 1 A drives also by means of gearing the roller 5 A. at the opposite extremity
at K, sketch No. 2; the roller 4 A drives the roller O, A, at the end K ; the roller 5 Å
drives the roller 2 A at the extremity J, sketch No. 2; 2 A drives the roller 6 A, at
the extremity K, sketch No. 2; and roller 6 A, drives roller 3 A at the extremity J,
sketch No. 2; the whole arrangement is disposed in such a way that the lower
rollers work upwards upon the upper rollers from right to left, sketch No. 2, on
side J, and upwards from left to right on side K, sketch No. 2.
The three upper rollers revolve opposite the four lower rollers, and any piece of
sheet ron which would be first taken along by the two outer rollers would be
caused to pass automatically through the entire system of rollers. By this means
the bucklings and creases of the sheet iron are compressed, and after having passed
from 2 to 3 times through the machine, this sheet iron comes out with a beautiful
flat surface, and on account of the different bends which take place everywhere is
completely free from rust or scales through their being broken up by the bends to
and firo.
According to the thickness of the sheet iron, and according to whether it has to
be rolled more or less, the upper roller system is lowered, and the teeth of the

page_text: driving wheels A 0-6 are arranged in such a way that they are continually in gear,
and the working of the upper roller system is not prejudiced during the elevation
and lowering which is produced by the hand wheel c, which causes the revolution
of the worms and the corresponding segments B as well as of the shafts H. These
latter are supported in the top beam G, and are provided with excentrics and
connecting rod P, which are connected with the lateral guide beam D by means of
the two bolts, in which guide beam the 3 upper rollers are supported. On each
side of the lower framing are placed two columns which are provided in the inside
with a guide E, for the purpose of guiding the cast-iron piece D with their three
upper rollers thereto adjusted; upon these columns are placed the two beams.
The action of the whole machine is transmitted when worked by hand from the
fly wheel S upon the axle X by means of the pinion II. a, to the shaft J and roller Z
by means of the wheel I. a.
When driven by steam or other motive power, the fly wheel S is suppressed, and
in its stead are fixed upon the roller Z direct a live and dead pulley; the transmission
is threefold.
In case rollers are required for very wide but thin sheet iron, there is adapted,
as the rollers must have certain sizes in proportion to the thickness of the sheet iron,
a framing containing rollers in the middle of the first mentioned rollers, as well
underneath as above. Each roller being thus provided with a counter roller to
prevent its flexion, as it is represented on the annexed Sheet II. The lower cast-
iron frame in which are fixed the 4 rollers is attached to the foundation, and the
upper roller frame is attached to the two columns E by means of two beams. If
however there exists similar rolling machines for straightening out sheet iron, in such
machines the lower rollers only are connected together by means of cog wheels
placed on the extremities of their axles, and the upper rollers run loose, and are
only put into motion through the sheet iron being run in between; therefore with
this kind of rolling machinery thick sheet iron can only be straightened which
exerts sufficient resistance against the rollers that they are compelled to turn round
with it; on the other hand when similar machines unprovided with gear are
employed for straightening thin plate iron for the manufacture of wagons and
other similar purposes, the upper rollers being first raised the sheet iron is introduced,
after which these upper rollers being lowered on the plate, this latter is drawn through
the machine by means of tongs.

the said August Wilke in the Great Seal Patent Office on the 25th January
1878.
AUGUST WILKE, of Braunschweig, Germany. "IMPROVEMENTS IN METAL ROLLING
MACHINES."
The construction consists, as represented in the annexed Drawings, of 7 wrought-
iron rollers 105 millimeters diameter, and 1 meter 5 long, and are intended for
sheet iron from 1 and a half to 4 millimeters thick; for thicker sheet iron the rollers
will have to be of a larger diameter.
The principal driving roller 1 A is put into motion by means of the counter shafts I.
and II., this former drives the roller 4 A at the extremity J, sketch No. 2; the
roller 1 A drives also by means of gearing the roller 5 A at the opposite extremity
at K, sketch No. 2; the roller 4 A drives the roller 0 A at the end K; the roller 5 Å
drives the roller 2 A at the extremity J, sketch No. 2; 2 A drives the roller 6 A at the
extremity K, sketch No. 2; and roller 6 A drives roller 3 A. at the extremity J,
sketch No. 2; the whole arrangement is disposed in such a way that the lower
rollers work upwards upon the upper rollers from right to left, sketch No. 2, on
side J, and upwards from left to right on side K, sketch No. 2.
The three upper rollers revolve opposite the four lower rollers, and any piece of
sheet iron which would be first taken along by the two outer rollers, would be
caused to pass automatically through the entire system of rollers. By this means
the bucklings and creases of the sheet iron are compressed, and after having passed
from 2 to 3 times through the machine, this sheet iron comes out with a beautiful
flat surface, and on account of the different bends which take place everywhere is
completely free from rust or scales through their being broken up by the bends to
and fro.
According to the thickness of the sheet iron, and according to whether it has to
be rolled more or less, the upper roller system is lowered, and the teeth of the driving
wheels A 0-6 are arranged in such a way that they are continually in gear, and
the working of the upper roller system is not prejudiced during the elevation and
lowering, which is produced by the hand wheel c, which causes the revolution of
the worms and the corresponding segments B as well as of the shafts H. These
latter are supported in the top beam G, and are provided with excentrics and
connecting rod P, which are connected with the lateral guide beam D by means of
the two bolts, in which guide beam the 3 upper rollers are supported. On each side
of the lower framing are placed two columns, which are provided in the inside with
a guide E for the purpose of guiding the cast-iron pieces D with their three upper
rollers thereto adjusted; upon these columns are placed the two beams.
The action of the whole machine is transmitted when worked by hand from the
fly wheel S upon the axle X by means of the pinion II. a, to the shaft J and roller Z
by means of the wheel I. a.
When driven by steam or other motive power the fly wheel S is suppressed, and
in its stead are fixed upon the roller Z direct a live and dead pulley; the transmission
is three fold.
In case rollers are required for very wide but thin sheet iron, there is adapted, as
the rollers must have certain sizes in proportion to the thickness of the sheet iron,
a framing containing rollers in the middle of the first-mentioned rollers, as well
underneath as above, Fig. 4 lower rollers, Fig. 5 upper rollers. Each roller being
thus provided with a counter roller to prevent its flexion, as it is represented on the
annexed Sheet of Drawings, which by an error are shown inverted in Figures 4, 5, 6,
and 7. The lower cast-iron frame, in which are fixed the 4 rollers, is attached to the
foundation, and the upper roller frame is attached to the two columns E by means
of two beams. If however there exists similar rolling machines for straightening
out sheet iron, in such machines the lower rollers only are connected together by

page_text: means of cog wheels placed on the extremities of their axles, and the upper rollers
run loose, and are only put into motion through the sheet iron being run in between ;
therefore with this kind of rolling machinery thick sheet iron only can be straightened,
which exerts sufficient resistance against the rollers that they are compelled to turn
round with it; on the other hand, when similar machines unprovided with gear are
employed for straightening thin plate iron for the manufacture of waggons and
other similar purposes, the upper rollers being first raised the sheet iron is introduced,
after which these upper rollers being lowered on the plate, this latter is drawn
through the machine by means of tongs.
The above described rolling machine rolls automatically thin as well as thick
sheet iron.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,―
Firstly. The gearing by means of long toothed driving wheels of three (or more
or less) upper rollers, and of the four (or more or less) lower rollers, as well as their
connection together by means of twelve (or more or less) of such driving gears as
above described.
Secondly. The double motion of the rollers, the raising and lowering of the same
with reference to one another whilst the machine is working, the limit of such
motion being two centimeters.
In witness whereof, I, the said August Wilke, have hereunto set my hand
and seal, this Fourteenth day of January, in the year of our Lord One
thousand eight hundred and seventy-eight.
AUGUST WILKE. (L.S.)
