PROVISIONAL SPECIFICATION.
A Machine Hoe.
I ROBERT ABELL of Brook Street Iron Works Derby in the County of Derby
Engineer do hereby declare the nature of this invention to be as follows:-
The blades spikes or cutters in machine hoes are usually fixed in position and act
in one direction only. Now the object of my invention is to provide a machine hoe
in which the blades or cutters are fixed upon rollers or barrels of any convenient size
and shape according to the character of the land or crops acted upon, such rollers or
barrels being interchangeable.
In carrying out my invention I provide a frame mounted upon suitable wheels
which carry gearing for transmitting motion to a roller or barrel revolving in bearings
fixed to the frame which may be provided with handles and a trailing or steering
wheel or wheels. Shafts or other hauling attachments are fixed to the front of the
frame.
The rollers or barrels are studded with blades or spikes projecting therefrom and
several of these rollers or barrels are provided to each machine; for instance for use
on level ground a roller or barrel of cylindrical section may be used, for clearing
ridges and furrows one of double cone or oval section may be substituted by the use
of which the shape of the ridge is maintained and the soil left light whilst weeds
and other refuse is shaken out thereof.
It will be seen that by any ordinary and well known mechanical devices the
rollers or barrels are caused to revolve on the inachine being drawn or propelled
forward and the said rollers or barrels may be thrown in or out of gear by means
of a lever or otherwise.

COMPLETE SPECIFICATION.
A Machine Hoe.
1 ROBERT ABELL of Brook Street Iron Works Derby in the County of Derby
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 :-
My invention has for its object an improved construction of machine hoe or
cultivator.
In machine hoes or cultivators as usually made the blades spikes or cutters
operating on the land or crops are generally fixed in position and act in one direction
only.
Now my invention is designed to provide a machine hoe or cultivator in which
rollers
the blades cutters hooks spikes or other devices of a like nature are fixed upon
or barrels of any convenient size diameter or contour according to the character of
the land or nature of the crops to be acted upon, such rollers or barrels being inter-
changeable for the purpose.
Referring to the accompanying sheet of drawings and to the figures and letters of
reference marked thereon.
Figure 1 is a plan of my apparatus the carrying or driving wheels and gearing
operated thereby being shewn in section.
On Figure 2 I shew on the right hand side a vertical section on the line a-a
(see Figure 1) of the driven roller barrel wheel or cone (P) with arms (N) and
blades (O) attached for hoeing furrows.

page_text: Figure 3 is a similar view shewing the arms (N) and blades (0) arranged for
hoeing flat land.
Figure 4 is a side elevation of the machine referred to in Figures 1 and 2.
In carrying out my invention I provide a frame A carrying a bracket B for
supporting the bearings of the driving or wheels F. shown in Figures 1 and 4.
Figure 1 shews such wheelstin. sectionals plan, and Figure 4 in elevation. The
dframe A is provided with guiding and manipulating handles C, C, and carries a
stay bracket D connecting said handles together and which stay bracket carries
a boss b in which is free to slide therein and be adjusted therein and held in a
suitable position by set screw d working in the boss or otherwise a rod or stem c
carrying the bearings of the guiding wheel D' which can thus be vertically
adjusted to suit the nature or configuration of the ground or the crop to be operated
upon or when the form of blades or equivalents has to be changed for various
purposes.
Cast on or affixed to the arms or spokes of one of the aforesaid driving wheels F
which may be toothed on their peripheries for ground hold, is a bevel wheel G for
driving a bevel pinion H keyed to or mounted on a shaft I revolving at one end in
a bearing e carried by a boss f on the arm 9 dependent from the bracket B¹ on the
frame A.
At the other end of the shaft I is a mitre wheel J engaging with a mitre wheel K
keyed to a shaft. L carried in bearings from a bracket B on the frame A.
On this shaft L are fixed bosses M M¹ carrying arms N having mounted on
them blades shewn in Figs. 1, 2 and 4 as set for hoeing furrows and in Fig. 3 as
set for hoeing flat ground.
In place of the blades O as shewn hooks spikes or other raking or scarifying
devices may be mounted on the arms N of the roller barrel wheel or cone P made
in sections so as to box in the gearing before referred to. Several of these rollers
barrels wheels or cones are provided to each machine.
For instance for use on level ground a roller or barrel of cylindrical section may
be used in place of the double cone section shewn in Figs. 1-4 or one of oval shape
may be used.
By this means the shape of the ridge or furrow is maintained and the soil left
light whilst weeds or other refuse is shaken out thereof. I may provide a clutch
device worked by lever or otherwise, and not shewn on the drawing to throw the
shaft L out of gear with the driving wheel F and so keep the blades O or equivalents
from revolving when not required to do so. E is a tug shackle on the frame A
for attachment of an animal or other tractive power.
The hoe or cultivator may be taken to pieces for transport and readily erected for
use while the advantage of being able easily and quickly to substitute one set of
implements for another will be apparent.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim' is
1-In a machine hoe or. cultivator the use of revolving interchangeable rollers
barrels shafts or other expedient for carrying various blades cutters or scarifiers for
operating on the land or crops, said rollers barrels shafts or other expedient for
.. carrying. blades cutters or..scarifiers being driven by gearing such us shewn or by
spur wheels chains belts or by any other suitable means from the main wheel or wheels
of the machine. as the same is drawn or propelled substantially as described.
2-The general arrangement and construction of machine hoe or cultivator sub-
stantially, as described. and.illustrated in the accompanying drawings.
