I JOHN GEORGE HALLS of Monkhams Lane Woodford Essex, Land Agent, do
hereby declare the nature of this invention to be as follows
The object of my Invention is to improve the mode of dibbling holes for potatoes
and other purposes and the utilizing of the present roller for those purposes,
For this purpose I take the ordinary roller, and remove the same from its spindle
or axle, and on one end of this axle I place a wheel, and at equal distances three or
more cylinders according to the number of rows of holes I wish to dibble, the second
wheel is then placed, and cylinders and wheels keyed in position.
These cylinders are regulated and kept in position by keys or nuts and the axle
or spindle passes through their centres.
The Dibblers are fitted to, and take the shape of the outer rim of the cylinders,
and are fitted into holes equidistant according to the nature of the work. For potatoes
they are diamond shaped at their bases with spear heads, for other purposes circular,
and are kept in position by split pins inside the cylinders.
To prevent an undue strain on the outer dibblers when turning the machine, I fit
on each side of the Rollernaves, Cams, these Cams have two holes bored in them
about 3 inches apart, in one hole is inserted the axle of the cylinders, and the other
is covered by a moveable flap kept in position by a pin; a piece of chain is attached
to this flap and passing over a roller is lead to a winch bolted to the Roller frame.
On removing the pins, by bearing down on the winch lever, the flap lifts, and
with it the Cylinder Axle, Cylinders, and Dibblers, the latter quite clear of
the soil.

To ensure a true line after completing one row of holes, a piece of wood is attached
at right angles to the frame, on this is a sliding piece of wood termed a marker
this has one end touching the ground, and makes a small furrow or guide line and
can be regulated at will. A length of chain attached to the outer end of the first
mentioned piece of wood is secured to a hook in the Roller frame to keep it at
right angles.

page_text: An Improved Machine for Dibbling Potatoes and other
'Purposes.
I, JOHN GEORGE HALLS of Monkhams Lane, Woodford, Essex, Land Agent 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 object of my invention is to provide improved means for dibbling holes for
potatoes, and for other purposes such invention permitting, if desired of the utiliza-
tion of the present or ordinary agricultural land roller, framework of same, or parts
thereof, for the above mentioned purposes and when not required to be used for
dibbling it may be re-converted and be used as an ordinary land roller.
According to my invention I remove the roller from its axle or shaft and in place
thereof I substitute two, three or more cylinders or drums, all according to the
number of the rows of holes I wish to dibble at one time. The distance of these
cylinders or drums from one another is adjustable according to the pitch of the rows
of holes to be made and the said drums are held to the shaft by bolts, keys, set
screws or otherwise.
The periphery of each roller is provided with dibblers, any number of which may
ho employed on one drum, the bases of which are fitted to the shape of the periphery
and are held thereto by bolts passing through boles in the drum, each drum may bo
formed with any number of holes; each of the drums when in action forming, by
means of the dibblers one row of holes.
The dibblers are made diamond shaped at their bases and have pointed or spear
shaped heads.
In order that my invention may be more fully understood and readily carried into
practice I will further describe the same with reference to the accompanying
drawings on which similar letters of reference refer to like parts in all the
figures.
Figure 1 shews in plan (a portion of the shafts being broken away) a machine
provided with drums and dibblers, adapted or constructed according to my invention;
Figure. 2 is an end view of the machine, and shewing same, as in Figure 1, out of
action; Figure 3 is an end elevation of the machine when in action, Figure 4 being
a horizontal section of same taken on the line a. y of Figure 3; Figure 5 is a per-
spective view of one of the drums removed from the machine, and provided with a set
of diamond-shaped and spear headed dibblers, according to my invention. Figure ò
shews one of the dibblers in an inverted position and removed from the drum.
A, is the rotative shaft, B, the cylinders or drums, and C the dibblers; the shaft A
is carried in bearings in the framework D of the machine to which the shafts E are
fixed.
The diamond shaped bases of the dibblers are formed, as hereinbefore stated, to fit
the circumference of the drum B and are set around same so that the acute angles of
the bases are in the direction of the circumference, and are held thereto by a bolt C
projecting from the base of the dibbler, and which is shewn at Figure 6, as being
formed with a square part to prevent any possibility of twist; the bolt C¹ is passed
through one of the holes formed in tho rim of the drum and is secured by a nut, but
a split pin or other devices may be employed for securing the dibbler to the drum B
according to circumstances. I generally prefer to make the rims of the drums B
slightly greater in width than the dibbler thereon, so that the edges of the holes

page_text: formed by the dibblers are rolled, and prevented from being filled in by the loose
soil.
In order to prevent an undue strain being placed on the dibblers when turning the
machine, and also to throw the dibblers out of action when required, 1. fit loosely on
each end of the shaft A and generally outside the framework D, cams or arms F,
which latter have at their ends carrying wheels G; the position of the cams or arms F
are controlled by winch or hand lovers H, fixed thereto and extending upwards above
the frame, so as to be within easy reach of the operator. The winch or hand levers
work against segment pieces or racks J. and the winch, or hand levers H may be
secured in any position desired by, for example, a pin being passed through a hole in
the segment and through the lever, as is shewn in the drawings or other equivalent
means may be employed.
On shifting the pins or moving the winch or hand levers H and consequently
altering the position of the cams or arms F-the-carrying_wheels_G_will_cause_the_
drums B and dibblers to be either raised clear of the soil, as at Figure 2, or lowered
for work as is shewn at Figure 3 all as desired.
By the employment of spear shaped dibblers constructed according to my inven-
tion, holes are pierced in the soil and the sides of the said holes are sharply formed
and defined and the edges rolled; the drums B one for each row of holes being
secured to the shaft A by for examplo either set screws or keys, are easily shifted, and
I am thus enabled to change the distance between the rows of the holes to be pro-
duced in the soil by simply moving the drums along the shaft A and this without
the loss of time necessary if the dibblers had to be detached from the drum and moved
singly.
if desired, to ensure a true line after completing one set of holes a gauge may be
added projecting at right angles from the end of the frame D and provided with an
adjustable or sliding pointer, not shown on the drawings; one end of the pointer may
score the ground and form a guide for the next set of holes.
As before stated the machine can when the dibbling drums are removed
have an ordinary roller substituted and the machine then be used for agricultural
rolling.
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 I claim is :—
1. A spear shaped dibbler of pyramidal form and having a diamond or rhombus
shaped base constructed as and for the purposes herein set forth.
2. In machinery for dibbling holes for potatoes, and for other purposes, the
arrangement of dibblers on cylinders or drums, there being one such drum for each
row of holes to be formed whereby the distance apart of the rows of holes may bo
varied by adjusting the relative positions of the said drums to each other substantially
as set forth.
3. In machinery for dibbling holes for potatoes and for other purposes, the
employment of an adjustable drum B, for each row of holes to be formed, in
combination with the spear shaped or pyramidal dibblers C substantially as herein
set forth.
4. The general arrangement and construction of machinery for dibbling holes for
potatoes and for other purposes substantially us described and illustrated with referenco
to the accompanying drawings together with any mere modification or modifications
thereof.
