Improvements in Horse-hoes.
I, CARL GINDLER, of Salzgitter, in the Province of Hanover, in the Empire
of Germany, Machine Maker, 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 :-
My invention relates to horse-hoes adapted for working upon either level or
unlevel ground. The regulating mechanism is placed at the rear, and can be
adjusted to work in any desired position horizontally, and is capable of being set
out at the same time in a horizontal direction laterally to the extent of half a metre
on either side, with the object of rendering a special front regulating mechanism
unnecessary, and of allowing the machine to work properly, even in case the draught
animal should suddenly swerve considerably from the direction of the rows of plants,
especially in an oblique plane.
The hoeing-tines have in all positions a depth of cut which is controllable and
is always equally great. This is attained by the connection of two jointed and
permanently horizontally arranged guide levers, with a horizontal tine or share
carrier which is jointed to the latter and rigid, and always takes up a position
vertical to the direction of travel, and to which are attached casings which are
capable of being shifted or locked at will, each of such casings receiving the stem
of one tine or share and guiding it vertically by means of a grooved roller, the
stem of each share being at the same time so connected to that of a caster wheel
that upon uneven ground the share and wheel rise and fall together.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which
Figure 1 is a longitudinal section of a horse-hoe constructed according to my
invention the section being taken on the line M-M of Figure 10.
Figures 2 to 9 are views of details of the regulating and hoeing mechanism.
Figure 10 is a plan of the machine.
Figures 11 and 12 are elevations respectively illustrating the two positions of the
share or tine, caster wheel, and regulating lever when working up a hill or slope
and in a depression in the land.
Figure 13 is a sectional side elevation of the machine, shewing the means for
securing a permanently horizontal position in working, and also the arrangement
for raising and locking the rear regulating mechanism for transport.
To the frame B carried by the extensible axle C of the travelling wheels, the
shafts A are so attached as to be capable of being shifted in a horizontal direction and
locked. To the axle of the travelling wheels are attached, in such a way as to be
capable of being shifted and locked, two blocks S which carry forked brackets T
(Figures 2 and 3). These blocks have jointed to them two guiding bars K
provided with handles L, and each of these guiding bars has joints at four
points n', na, na, n³.
The rear ends of the guiding bars K carry through the intervention of the
joints n a rigid beam J, to which are attached, in such a way as to be adjustable at
will and capable of being locked by means of wedges at any desired distance
apart, several casings 1 (Figures 1, 5, 6 and 7). Each of these casings / is provided
with four grooved rollers 1, 2, 3, 4, Figure 5, which allow the stems of the shares
to slide easily and so guide them vertically that the shares N cannot rotate when in
work, but are compelled to act always in a direction parallel to that of the draught
of the machine.
To the upper part of the stem of each share there is connected by means of a
bracket o and screw bolt i, the upper part of the stem of a caster wheel P, and

page_text: this stem is guided parallel to the stem of the share by means of a slot c. c², c³, c
(Figure 10) in the casing 1. The caster wheels P which always precede their
respective shares, are intended to give the same depth of cut to each share, and to
this end the shares N are so adjusted with reference to their caster wheels P, that
they extend beyond the latter downwards to a given distance.
Since the caster wheels and shares are so guided, as regards their stems as to slide
easily and vertically in their casings, each caster wheel adapts itself easily to the
condition of the surface of the ground at any given moment, and thus determines
the depth of cut of the share which is connected with it.
In order that the depth of cut of the shares may be regulated according to the
requirements of the case, a row of holes placed above one another is provided in
the stem of the caster wheels (Figure 6), so that by placing the bolt i, which passes
through the bracket o, in a higher or lower hole, the shares are caused to cut more
or less deeply. In order that the direction of the cut may be properly adjusted,
according to requirement, the rigid beam J is provided with quadrants at the
points where it is jointed to the two regulating or guiding bars K in which quadrant
several holes are drilled (Figure 2). By causing the rigid beam to rotate at the
points n at which it is jointed, and by the connection of the quadrants k with the
handles L, which are rigidly connected to the guiding bars K with the co-operation
of the connecting bolts placed in the higher or lower holes of the quadrantsk,
the shares are caused to take up a position more or less inclined to the guiding bars.
If, in the case of special kinds of plants, it is desirable to allow the shares to
work with a superficial cut the casings on the beam J may be reversed in front
and behind as shewn in Figures 10, 11 and 12.
With my horse-hoe I can also so arrange the guiding bars K and beam J as to
ensure their keeping a horizontal position and in this enforced horizontal position
to cause the said beam to project on one side or the other to the extent of half a
metre. For this purpose, rigid beams E' (Figures 1 and 13) are secured to the
posts E of the frame B, which posts rest upon the axle C of the travelling wheels,
and these beams E are directed obliquely outwards and backwards and carry in
their outer ends a horizontal shaft f. On this shaft two cranks N' are secured by
means of screws, and these cranks are at the same distance from each other as the
blocks S and each of them lies in a plane directed vertically to the axle of the
travelling wheels, and passing through the middle of the corresponding block S,
(Figure 10). The two cranks N2 are connected by means of joints n³, to traction
rods V, which again are connected by joints n to the corresponding guiding bars K.
On one end of the shaft is secured a stop-disc h, Figures 10 and 13, which is
provided with two notches a, a'. By turning the lifting lever which is attached
to the shaft, in one or the other direction a pawl G which is pivotted on the
beam E¹ is caused to engage with one or the other of these notches.
If the pawl G
be in engagement with the notch of the stop-wheel h, the hoeing machine is in
position for transport, in which case the two guiding bars K are situated in the
corresponding forked brackets T attached to the blocks S, so as to guard against
lateral shifting. If on the contrary the pawl engages with the notch a', as shewn
in Figure 13, the two guiding bars K are forced into a horizontal position with the
rigid beam to which they are jointed, and are thus in position for hoeing.
In order that there may be no damage to the plants or to the seed even when the
draught animal departs to a considerable extent from the direction of the rows of
plants, the two joints n², n³, already mentioned are provided, by means of which
the beam J is able to execute a horizontal lateral movement of half a metre on
either side, without any corresponding variation in the proper position of the cut,
or the depth of entrance of the shares.
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
1 claim is :-
1. A horse-hoe in which each of the stems of the tines or shares is guided

page_text: vertically by means of rollers and is connected by a bracket to the stem of a
caster wheel in such a way as to be adjustable not only vertically but also
horizontally, so that the shares and wheels rise and fall together upon uneven
ground without the least variation in the cut, with the object of allowing the shares
to penetrate the soil to an extent which shall be as nearly equal as possible in all
positions, substantially as herein before described.
2. A horse-hoe of the kind claimed in Claim 1, in which the stem of each tine
or share is contained in a casing which can not only be shifted and locked at
will upon a rigid beam, but can be fastened upon either the front or rear side of
the said beam so as to allow the shares to make a superficial cut, substantially as
hereinbefore described.
3. The improved horse-hoe hereinbefore described and illustrated in the accom-
panying drawings.
Dated the 3rd day of January 1894.
