J WILHELM BANSEN of Kattowitz in Upper-Silesia in the Kingdom of Prussia,
German Empire, Engineer, do hereby declare the nature of this invention to be as
follows:
The improvements allow the advantageable arrangement to put all the sets of
rollers one behind the other thereby needing less skilled and a smaller number of
workmen as heretofore; and it is also possible to make hoop-iron of nearly 500 feet
and smoothing, polishing and winding up the same in a rational way and to a much
smaller expense.
There are for instance three pairs of rolls arranged one behind the other and in a
horizontal line which rest in standards as in the usual manner. These rolls are flat-
grooved-rolls and contain the several grooves which are separated and of different
sizes.
As most essential in the arrangement of the rollers may be mentioned that the
first set has its matrices cut in the under roll, whilst the second pair has its matrices
in the upper-roll and the third set again in the under-roll by what construction the
turning of the material to be rolled is prevented and the formation of seams is
completely avoided.
Behind these rollers the dressing-rolls are situated, and then the polishing-rolls.
Between the dressing- and polishing-rollers, the scraper is inserted which can be used
as the common scrapers. To avoid the damageable tension between one set of rollers
and the next one, the following arrangement is given to the guides.
The grooved rolls receive sets of guides one upon the other, between which the
iron is passing, the under-ones. are firmly fastened, whilst the upper-ones consist out
of two parts which are hinged together and of which the one part can be turned
upward.
This construction is chosen because it is profitable that the first pair of rollers
delivers a little more of iron than the second one, so that the iron bends upward and
raises thereby the levers of the upper-guide. The same will happen at the second
and third set of rollers, so that no tension can be between the parts of the iron passing
the rollers, and the workman can easily see by the raised arms of the upper guides,

page_text: that every thing is in order. This manner of guiding should go till to the polishing-
rolls. Before these rolls the scraper is arranged and connected with a frame that
serves as a last guide to the polishing rolls and which can move up and down
according as the iron may go.
Behind the polishing-roller is situated the winding-drum with a separate pushing-
off-cylinder which is movable on the drum. The pushing-off-cylinder and the drum
are connected by four long bolts that pass through them both, and are provided with
screw-threads. Besides this, the four spindles possess toothed wheels which engage
all in another wheel, situated in the centre, which is keyed to the shaft with which the
drum is rotating. In front of the last mentioned toothed wheel is a hand wheel and
by turning this hand wheel, the pushing-off-cylinders can be made gliding over the
drum in the one or the other direction.
On the periphery of the drum are radially arranged a number of friction-rolls which
rest movably in guides of an outside casing or frame of the drum and which are
constantly pressed down upon the rotating drum by spiral-springs. The strain of the
springs can be regulated by screws and so forth, well known to any mechanic, so that,
when the bundle of hoop-iron on the drum becomes thicker, the rolls may give way
more and more. Between two of these rollers is always standing a guide for the
hoop-iron to be wound up, which guides are bedded in the same manner, as the last
named rolls. It is not necessary that the rolls and guides on the drum are all the
time in contact with the drum, but it will suffice by doing so, when the first course of
the hoop-iron is wound up. Besides this, the rolls and guides must be lifted when the
whole bundle shall be pushed off from the drum.
For this reason each of the rolls as well as the guides are provided with an angle-
lever, to the free ends of which are fastened connecting-rods from one to the other,
and the free end of the first lever is long enough that it may be pressed down by
hand, for what purpose it is also specially weighted.
After such a bundle of hoop-iron is pushed off from the drum, it is put on a
drawing-out-table by which the whole ring of hoop-iron shall receive an oblong
shape. For this purpose is under the table a spindle possessing a right-and-left-
handed screw-thread, which move each a slide being embedded in the table-board.
These slides possess each a roll, projecting out of the table around which rolls the ring
of hoop-iron is laid. By turning a hand-wheel on the spindle, the slides and also the
rolls will move in opposite directions and the hoop-iron will be drawn into in an
oblong shape.
It is evident, that by all these improvements the expenses for manufacturing hoop-
iron are much reduced, as the mill does much of the work, that heretofore had to be
done by hand, and at the same time doing this in the most exact manner.

page_text: Improvements in Rolling-mills for the Manufacture of Hoop-iron.
I, WILHELM BANSEN of Kattowitz in Upper Silesia in the Kingdom of Prussia,
German Empire, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The improvements described hereafter, and shown in the accompanying drawings
relate to an improved method of making hoop iron or flat bar iron and allow the
advantageous arrangement of placing the sets of rollers one behind the other, thereby
requiring a smaller number of workmen to manage the same, than in the older
methods and it is possible, in this machine, to roll hoop-iron in length of 500 feet, and
to smooth and polish the same, at a much smaller cost than was possible in the older
machines.
In this arrangement there are the three sets of rolls A B C and the dressing rolls D
and the polishing rolls E with the scraper F placed one behind the other.
But the principal thing in this invention is that the first pair of rolls has its matrices
formed in the under roll, and while the second pair has its matrices in the upper roll,
and again the third pair has its matrices in the under roll; the advantages of thus
arranging the matrices are very great and shall be hereinafter described.
Another improvement consists in the construction and use of the guides y g¹ 9 9¹? I³,
by which tension on the iron is avoided, if one pair of rolls should take more iron
than the foregoing roll delivers.
The following is a description of the drawings, similar letters denote similar parts
throughout the figures.
Fig. 1 shows a longitudinal sectional view of this arrangement for rolling hoop
iron, with the winding drum d for the finished iron.
Fig. 2 shows a longitudinal sectional view of the same arrangement for rolling flat
iron without the winding drum, in which the polishing rollers are removed about
20 meters away.
Fig. 3 shows a top view or plan of the hoop iron rolling mill fig. 1.
Fig. 4 shows a front view of the scraper F and polishing rolls E.
Fig. 5 and 6 show elevation and plan of the guides for the iron between each set of
rolls.
Figs. 7 and 8, 8 show detailed views on a larger scale of the guides.
Fig. 9, 10 and 11 show detail views of the three set of rolls used, showing the
matrices in alternate order..
Figs. 12-13-14 show views of the bundling table for pressing the boop iron,
after coming from the winding drum, into oblong shaped bundles ready for the
market.
The arrangement of my rolling mill for hoop and flat-bar iron, as seen by reference
to the annexed drawings, consists of the three sets of rolls A B C which rest in

page_text: bearings in the standards 1, 2, 3, and arranged horizontally one behind the other in
the usual manner.
These rolls have grooves corresponding to the different sizes of iron required to be
rolled as can be seen in figs. 9, 10, 11. The most essential feature in these rolls is,
that the grooves are so cut in the rolls, so that the first pair A has its matrices in the
under roll, the second pair its matrices in the upper roll and the third pair Cits
matrices in the under roll or in reverse order, by this arrangement the turning of the
material to be rolled is avoided.
Behind these rolls, the dressing rolls D, and the polishing rolls E are situated; the
polishing rolls are fitted with a scraper F which is constructed and operated in
the well known manner.
In order to avoid damageable tension of the iron when passing from the rolls A to B
or from rolls B to C each pair of rolls is fitted with guides, g g g g', the under
guides g being fixed rigidly while the upper guides are hinged, so that they can
rise, and let the iron take the form as shown by the dotted lines in fig. 5, thus freeing
the iron rolled from any strain, if one pair of rolls should take more iron than what
the pair before delivers, and draws the workman's attention to it, who can therefore
alter the receiving power of one pair of rolls to suit delivery power of the pair
before.
The grooved rolls are driven by means of cog wheels xy y' figs. 1-2 and the
polishing rolls E by means of belts over the conical pulleys P Q by means of which
the speed of the dressing and polishing rolls can be altered at will.
The advantages of the above arrangements are as follows; If at any time the iron
should be brought into tension on account of one pair of rolls taking more iron than
the foregoing pair supplies, allows of the workman noticing this and regulating the
rolls in consequence, by raising or lowering the upper roll as the case requires; and
by altering the position of the driving belts on the conical pulleys, and the iron bends
up as seen by the dotted lines in fig. 5 and with it the guides gg; the guides
being fitted to overy pair of rolls and after the iron comes from the dressing rolls it is
led to the polishing rolls along the bar 9 which moves up and down with the
scraper F; for this reason the scraper F is connected to the frame by the bars ss,
Fig. 4.
The grooved rolls A, B, C rest in bearings fixed to the base plate by means of
screws or any other suitable means, but the dressing and polishing rolls rest in
bearings which can move in a longitudinal direction of the axis of the rolls, so that
the entire surface of the rolls can be used for all the grooves.
Behind the polishing rolls is placed the winding up drum d which winds up the
hoop iron after coming from the rolls and is constructed and operates as follows:
The drum fis made to slide over the drum d on which the hoop iron is wound after
coming from the rolls, and when a sufficient quantity of iron is rolled on the drum d
the hand wheel e is turned and with it the cog wheel which turns the four cog
wheels m m m m, which are fastened to the four screwed spindles nnnn which screw
into the drum and draws it over the drum d and so forces the roll of hoop iron off.
In order to roll the hoop iron evenly and to keep it fast on the drum d, the rim of
the drum has a number of small rollers oooo and guides presting on it, which are
fitted in the frame work T and all connected by a train of levers o¹¹ and forced
against the drum d by the aid of springs o³, but the pressure can be released, by
means of the lever o³, which can be worked by hand; between each roller is a
guide p.
