EDUARD OTTO, of Wuerben, in the Kingdom of Prussia, and GUSTAV PEISKER
and AUGUST RITTNER, both of Schweidnitz, in the Kingdom of Prussia, AN
IMPROVED LAND-ROLL ""
•
Our invention relates to an improved land roll or roller, and more particularly to
a land roller of that type which has motion imparted to it by means of a portable
steam-engine or similar motor, for the purpose of being rolled over a field, in order
to break up the clods. Land-rollers of this type, which we shall hereinafter term
"steam land rollers," as heretofore constructed, present the great disadvantage of
offering great difficulty to a turning movement to the right or left; another
disadvantage being that the guide-wheels of such land-rollers always leave deep
impressions in the field across which the said rollers are rolled. It has been tried
to smooth or efface such impressions by combining the said steam land-roller with
a harrow, but this would make the said land-roller so complicated and clumsy that
it could not be moved along the public roads with ease, and would have to be taken
entirely apart before being moved from one place to another.
The object of our said invention is to obviate these difficulties, and to provide
means to allow of readily turning the said steam land-roller to the right and left
when drawn or rolled across the field or land. For this purpose our said invention
is as follows. We mount upon a suitable shaft the land roller proper which is
preferably composed of two such rollers mounted upon the said shaft alongside of
each other. To one of the heads of the said land rollers, or to the outer head of
one of the said rollers if two of them are mounted upon the same shaft, is keyed a
friction-wheel, the said roller or rollers being surrounded by a substantial frame
which is suspended by two bearings applied to the said shaft. At either side of the

page_text: said. friction-wheel are arranged two other friction-wheels of smaller diameter,
journalled in the frame, and capable of imparting their rotary motion, by means of
two corresponding bevel gears, to a shaft, carrying near both of its ends a bevel-
pinion, each in gear with two similar pinions, each mounted upon one end of two
screw threaded shafts, arranged respectively in front and in rear of the said land
roller or rollers.
The plates, carrying the hooks serving for the reception of the rope by means of
which the said land roll is drawn or rolled across the land or field, are fitted to
the said frame, so as to slide upon the same in front and in rear of the said roller.
Each of the said plates has, applied. to its under surface, a threaded nut, which fits
upon the threaded part of the said screw threaded shafts, so that on rotating these
said shafts either to the right or to the left, the said nuts will be moved to the
right and to the left, respectively; and since the said plates, to the under surface of
which the said nuts are applied, are sliding on the said frame, and are suitably
connected at their rear ends to the land-roller proper, the latter and the whole
frame suspended by its shaft will also be turned to the right or to the left.
As has been set forth, the said friction-wheels, and bevel gears are arranged at
one end of the said land rollers. The said friction-wheels are put in operation by
the operator revolving a hand-wheel mounted upon each end of a screwed shaft,
by the rotation of which one of the said bearings, by which the said frame is
suspended, is caused to slide upon the said frame, either in a forward or backward
direction, thereby bringing one of the said small friction wheels in contact with
the said other friction wheel, rigidly connected to one of the heads of the said land
roller and rotating therewith. Now, if the said land roller is to be turned to one
side, that is to say either to the right or to the left as may be desired, the friction
gearing from the roller is thrown into gear by the rotation of the screw threaded
shaft, by means of the said hand-wheel, and imparts the necessary sliding motion
to the roller bearing. By the rotation of the said friction gear, transmitted
through the before described bevil wheels and shafts, the transverse screw
threaded shafts are rotated in the proper direction, thereby causing one of the said
plates having the said hooks to slide to the right and the other one to slide to the
left, thus turning the said land-roller and its frame in the desired direction, as will
be readily understood.
Two small rollers are arranged underneath the said frame, near the end carrying.
"the several gearings, for the purpose of balancing the same. Two seats are also
applied to this end for the operator, so that he can readily turn the said hand-
wheels when the land roller.is in operation.

IMPROVED LAND-ROLL
">
Our invention relates to an improved land-roll or roller, and more particularly to
a land-roller of that type which has motion imparted to it by means of a portable
steam-engine or similar motor, for the purpose of being rolled over a field, in order
to break up the clads. Land-rollers of this type, which we shall hereinafter term
"steam land-rollers," as heretofore constructed, present the great disadvantage of
offering great difficulty to a turning movement to the right or left; another dis-
advantage being that the guide-wheels of such land-rollers always leave deep
impressions in the field across which the said rollers are rolled: It has been tried
to smooth or efface such impressions by combining the said steam land-roller with a
harrow, but this would make the said land-roller so complicated and clumsy that
it could not be moved along the public roads with ease, and would have to be taken
entirely apart before being moved from one place to another.
The object of our said invention is to obviate these difficulties, and to provide
means to allow of readily turning the said steam land roller to the right and left
when drawn or rolled across the field or land, and this will be best understood by
reference to the following description of the drawings, in which :-
Figure 1 is a side elevation, partly in section, of our improved steam land
roller.
Figure 2 is a vertical transverse section of same, on the line A B, Figure 1.
Figure 3 is a horizontal section on line.CD, same Figure,

drawn on an enlarged scale.
bis the land-roller proper, which is preferably composed of two cylinders or

rigidly fastened to the one of the heads of the said land roller b, or to the outer
head of one of the said cylinders or rolls, if two of them are mounted upon the
same shaft a, as in the present instance. d is a substantial frame of iron or other
suitable form or material, surrounding the land roller band being suspended by two
bearings e and f applied to the said shaft a. g and h are two other friction-wheels
of smaller diameter arranged at either side of the said friction wheel c and mounted
upon the inner ends of short shafts, which are journalled in the frame d and carry.
on their outer ends two bevel gears i and k in gear with two similar bevelled
pinions rigidly mounted upon the shaft !.
The shaft, near one end, is provided with the bevel gear p, while near its other
end it carries a similar bevelled pinion o. These bevel-gears p and o are in gear
with two similar bevel-gears mounted upon one end of the two threaded shafts m
and n, respectively, the one of the said shafts being arranged in front and the other
in rear of the land roll b.
The plates q carrying the hooks serving for the reception of the rope by means
of which the land roller is drawn across the land or field, are fitted to the frame d,
so as to slide upon the same in front and in rear of the land roll b. Each of the
said hook plates q has, applied to its under surface, a screw-nut which fits and is
screwed upon the threaded part of the threaded shafts m and n, respectively, so

page_text: that on rotating the latter in opposite directions one of the said nuts will be
moved to the right and the other to the left. The hook-plates q are properly
connected at their inner ends to the land-roll b by means of the connecting
pieces. q¹.
As has been set forth, the said friction-wheels and bevel-gears are arranged near
one end of the land roller b. Near the same end are also applied two seats for
the operator, and two rollers v and w for balancing the frame.
The bearing e herein before referred to is connected to the frame d so as to allow
of sliding on the same to a proper extent, and by means of a suitable connecting
link and screw-nut lengthwise motion is imparted to the said bearing e from the
threaded shaft s which can be turned from either of the operator's scats 7 by means
of a hand-wheel 8¹.
Having thus described the construction of our improved land roller we now
proceed to describe its operation.
The land-reller having been put in motion and the operator being desirous of
changing its course, he will simply have to turn the hand-wheel s¹ next to the
respective seat he occupies, and by means of the threaded shaft s and its connecting
link he will thus cause the bearing e to slide but slightly forward or backward
upon the frame d and to give such a turn to the shaft a and land roller b as to
bring the friction wheel c rigidly applied to the head of the roll b in contact either
with the friction wheel h or with the friction wheel g. The frictional contact
between the wheel c and the wheel (or the wheel g) will cause the bevel-gear i
(or the bevel-gear ) to rotate in a direction opposite to the rotation of the land
roller, and thus by means of the bevel-gears mounted upon the shaft and in gear
with the bevel gears i and k, respectively, the said shaft will be revolved either
to the right or to the left as the case may be, and as will be readily understood
from Figure 3 of the drawing. The shaft 7, by means of the bevel-gears p and o,
will then turn the threaded shafts m and n in opposite directions so that the
screw-nut of one of the hook-plates q will be moved to the right and that of the
other hook-plate q to the left, the said hook-plates sliding on the frame & partaking
in the respective movements of their screw-nuts and by means of the connecting
pieces turning the land-roll b and the framed suspended by its shaft a either
to the right or to the left as the case may be and as will be readily understood.
For the practical purposes of our invention we deem it preferable to arrange the
parts and threaded shafts in such a manner as to cause the land roller to change
its course to the right as soon as the operator having his seat behind the said roller
shall turn the hand-wheel and the shaft s to the right, and vice versa.
In order to allow of readily turning our said improved land-roller also by hand,
instead of automatically as described, we provide the hand-wheels t and u near the
outer ends of the shafts m and n, said hand-wheels being of practical use only
when the land roller is not in motion.
Having now described and ascertained the nature of our invention and the
manner of carrying the same into effect be it known that what we claim as novel
.and desire to protect by Letters Patent is :-
First. A land roller having the friction wheel c which by means of being brought
in contact either with the friction wheel g or with the friction wheel h will cause
the shaft to rotate to the right or to the left, and, by means of the bevel gears o
and p, impart rotary motion to the shafts m and n so as to move the hook plates q
in opposite directions and thereby to change the course of the land roller
substantially as set forth
Second. The combination in a land-roller with the friction wheel c of the
movable bearing c and the threaded shaft s, substantially as and for the purpose
specified.
gears
i
Third. The combination, in a land-roller, with the shaft of the bevel
and arranged as set forth, and the friction wheels and g, substantially as and
for the purpose specified.

page_text: Fourth. The combination, in a land-roller, with the threaded shafts m and n
substantially arranged as described, of the hook-plates 9 and the connecting
pieces q¹, substantially as and for the purpose set forth.
In witness whereof we, the said Eduard Otto, Gustav Peisker, and August
Rittner, have hereunto set our hands and seals this twentieth day of December
in the year of our Lord One thousand eight hundred and eighty-three.
