IMPROVEMENTS IN HORSE HOES FOR HOEING TURNIPS AND OTHER ROOT CROPS
Year: 1884

page_text: COMPLETE SPECIFICATION.
ALFRED DYBALL and ARTHUR PAYNE, West Raynham, Loaffham, Norfolk,
Engineers, do hereby declare the nature of their invention for IMPROVEMENTS IN
HORSE HOES FOR HOEING TURNIPS AND OTHER ROOT CROPS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
In horse hoes in which revolving shield plates are used to protect the young
plants from being covered up by the earth displaced by the hocs, we make each
shield plate with a groove in that side of it which is next to the point of the hoe
so that the point of the hoe may enter the groove and be thereby protected. The
outer edge of the revolving shield plates we also make bevilled so that it may
readily enter the ground.
Whore the stem which carries the axis of one of these shield plates is secured to
the stem which carries the hoe and where the stem of the hoe is secured to the
horizontal cross bar or beam of the machine we secure them by adjusting bosses
which allow them to be set at any angle required, we also construct the machine so
that the depth of cut may be regulated by a lever handle which can be worked
from behind the machine without stopping. The horizontal beam to which the
stems of the hoes are secured we make of two slotted bars at a distance apart from
one another and trussed or tied together at intervals.
Figure 1 is a back elevation of parts of a horse hoe having the improvements
above described combined in it. Figure 2 is a vertical section of the same on the
line A B Figure 1 looking towards the right hand and Figure 3 is a vertical
section on the same line looking towards the left hand. Figure 4 shews on a larger
scale one of the grooved shield plates and Figures 5 shew views of the inner sides
of the two parts of one of the bosses for allowing the stems of the hoes and the
stems which carry the shield plates to be set at any required angle. Figure 6
shews a plan view and Figure 7 a front elevation of the double trussed beam to
which the stems of the hoes are secured. Figure 8 shews a plan view of one of
the bosses for securing the stems of the hoes to the trussed beam, this figure is drawn
to the same scale as Figures 5. Figure 9 shews a side elevation of the complete
machine drawn to a small scale.
In Figure 1 one pair only of hoes is shewn but hoes for taking two three or
more rows might be secured to the machine as desired.
In the several figures a are the revolving shield plates with a groove or recess
formed in one side of them for the point of the hoe b to enter. This groove or
recess is best seen in the section of one of these shield plates shewn at Figure 4.

Figures 1 and 3 so that no weeds can get caught over the point of the hoe or be
wedged between it and the shield-c are tho adjusting bosses by which the stems
which carry
the revolving shield plates are connected to the stems which carry the
hoes and dare the adjusting bosses by which these latter stems are connected to
the trussed horizontal beam c.
As will be seen each boss c is made in two parts and a bolt passes through both.
The end of the bolt is formed with an eye through which the hoe stem passes and

bolt being shifted along the slot and of the hoe stem being affixed to tho frame in
any position desired. When the nut is screwed on to the rear end of the bolt the
hoe stem is drawn against the front part of the boss and the two parts of the boss
are drawn together whilst the back part of the boss is drawn against the beam e
and the parts so all held together. One part of the boss has standing out from it a
tooth or projection y to enter any one or other of a number of grooves & formed
in the other part of the boss when the two parts are drawn together as above
described so that the hoe stems may in this manner be set to any angle desired.
The bosses c for securing the stems which carry the revolving shield plates to the
As will be
stems of the hoes are constructed in substantially the same manner.
seen from the Drawings the hoes can be secured either to the front or back bar of
the beam e or to both and can be fixed to thein at any part of their length. The
horizontal beam e is carried in the ordinary frames f-these frames at their forward
end are suspended from crank pins g which project from discs which are fixed on
an axis h carried by brackets i from the cross bark of the main frame of the
inachine to which the shafts are attached. On the axis is a pinion which gears
with a toothed wheel m also carried by one of the brackets i. The toothed
wheel m, has fixed to it a lever arm n, which projects back to the rear end of the
machine and by which it can be turned whilst the machine is at work. The lever
arm can be held in any desired position by being sprung under one or other of a
number of pegs o as shown at Figure 1.
In this way the forward and of the frames f can be raised or lowered and the
depth to which the hoes are allowed to cut can be adjusted without stopping the
machine. The frames fare also upheld as is usual by chains p from lever arins q.
These as shewn at Figures 2 and 9 can be raised by another lever r, in the ordinary
manner whenever the hoes are to be lifted out of work.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
wo claim is
1. The circular revolving shield plates with a groove or recess on one of their
sides for the points of the hoes to enter substantially as described.
2. Securing the hoes to the frame of the machine and securing the stems
which carry the revolving shield plates to the stems of the hoes by adjustable
bosses substantially as described to allow of them being fixed at any desired angle.
3. The combination of parts substantially as hereinbefore described for permitting
the depth of cut to be altered from behind without stopping the machine substan-
tially as described.
4. The employment of a double trussed beam 6, constructed substantially as
described and illustrated in the Drawing for carrying the hoes.
