PROVISIONAL SPECIFICATION.
Improvements in Harvesting Machines.
We, JAMES. HORNSBY, and JOHN INNOCENT, both of Spittlegate Works, Grantham,
in the County of Lincoln, Engineers, do hereby declare the nature of this invention
to be as follows:-.
It has been before: proposed to employ a conical rotating divider at the side of the
machine next to the uncut crop but difficulties have arisen in driving such dividers.
Sometimes they have been driven by chains or bands from a pulley upon the divider
wheel but in such cases they have either been so arranged that the length of the
driving chain has had to be altered for each different height of the cutters or else the
chain has been led to the front end of the divider. which necessitates, having this end
of, considerable size instead of pointed as is desirable.
The object of our invention is to overcome these objections.
We employ a conical rotating divider driven at its rear end in such a way either
that no adjustment is required to suit the different heights of the cutter or that such
adjustment can be, very readily made.
When driving from a pulley on the divider wheel we lead the chain from it in an
approximately horizontal direction to two guide pulleys on the frame of the machine
and then upwards to, the rear end of the divider when this is done a small vertical
movement of the frame does not materially tighten or loosen the chain or the two
guide. pulleys may be mounted upon a bracket which is adjustable relatively to the
frame.
Sometimes we use two pitch chains, one chain running from the divider wheel to
the adjustable bracket the other chain running from the adjustable bracket to the roll
with mitre or bevel wheels on the adjustable bracket to transmit the motion from one
chain to the other.
When the rotary divider is used on sheaf binding harvesters motion may be taken
from one or other of the working parts of the machine which move up and down
with the cutter and transmitted by chains or other suitable means across the back of
the platform to the rotary divider.
Or motion may be taken, from the divider side roller, operated by the platform
canvas.
We prefer to make the conical divider hollow employing sheet metal supported by
internal wooden discs and on the outside we fix longitudinal laths of wood one of
which covers the joint between the edges, of the sheet of metal.

COMPLETE SPECIFICATION.
Improvements in Harvesting Machines.
We, JAMES HORNSBY, and JOHN INNOCENT, both of Spittlegate Works, Grantham,
in the County of Lincoln, Engineers, 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:-
It has been before proposed to employ a conical rotating divider at the side of the
machine next to the uncut crop but difficulties have arisen in driving such dividers.
Sometimes they have been driven by chains or bands from a pulley upon the divider
wheel but in such cases they have either been so arranged that the length of the
driving chain has had to be altered for each different height of the cutters or else the

page_text: chain has been led to the front end of the divider which necessitates having this end
of considerable size instead of pointed as is desirable.
The object of our invention is to overcome these objections.
We employ a conical rotating divider driven at its rear end in such a way either
that no adjustment is required to suit the different heights of the cutter or that such
adjustment can be very readily made.
When driving from a pulley a on the divider wheel b as shown in Figure 1 we lead
the chain from it in an approximately horizontal direction to two guide pulleys cc
on the frame of the machine and then upwards to the rear end of the divider when
this is done a small vertical movement of the frame does not materially tighten or
loosen the chain or the two guide pulleys may be mounted upon a bracket e which is
adjustable relatively to the frame.

Sometimes we use two pitch chains as shown in Figures 2 and 3 one chain frunning
from the divider wheel b to the adjustable bracket e the other chain 9 running from
the adjustable bracket e to the roll with mitre or bevel wheels h h on the adjustable
bracket to transmit the motion from one chain to the other.
When the rotary divider is used on sheaf binding harvesters motion may be taken
from one or other of the working parts of the machine which move up and down with
the cutter and transmitted by chains or other suitable means across the back of the
platform to the rotary divider.
Thus in Figures 4 and 5 the motion is taken by the chain f from a chain wheel j
fixed on the rear end of the right hand spindle of the platform canvas to the chain
wheel whose axis carries the pinion gearing with the wheel m whose axis carries
the chain wheel n which by means of the chain g drives the chain wheel at the rear
end of the divider.
Or motion may be taken from the divider side roller operated by the platform
canvas.
We prefer to make the conical divider roller employing sheet metal supported by
internal wooden discs and on the outside we fix longitudinal laths of wood o o one of
which covers the joint between the edges of the sheet of metal.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A rotary divider driven at its rear by gear from the divider wheel such gear
being so arranged that it adjusts itself to slight variations of the height of the frame
substantially as described.
2. A rotary divider driven at its rear by gear from a working part which moves
up and down with the frame substantially as described.
3. A rotary divider constructed of sheet metal supported on internal discs substan-
tially as described.
4. The arrangement substantially as described and shown at Figure 1.
5. The arrangement substantially as described and shown at Figures 2 and 3.
6. The arrangement substantially as described and shown at Figures 4 and 5.
