ALFRED GREIG of Leeds in the County of York. " IMPROVEMENTS IN
APPARATUS FOR STEAM CULTIVATION"
My invention applies firstly to winding engines used for steam cultivation in
which the winding drums revolve vertically on the hind axle of the engine and
has for its object to improve the coiling or laying of the ropes evenly on theso
drums.
To effect this, the rope, instead of being taken direct off the back of the engine
or carried round a pulley or sheave fixed under the engine direct to the implement,
is taken forward to as great a distance as possible from the drum and passed round
a sheave fastened to the front axle or other suitable place at a distance from the
drum; it is then passed back and around another sheave fastened to the tank at
the hind end of the engine. By this means sufficient distance is obtained between
the drum and the fixed point. from which the rope is guided on to the drum to
allow the rope to coil itself evenly which it will not do when the point at which it
is paid on and off the engine is close to the drum.
;
The above arrangement admits of the sheave round which the rope passes to the
implement being placed close to the hind axle and so the tendency of the strain to
turn the engine round is decreased. Also implements for ordinary work can be pulled
level with the engine thus. decreasing the width of the headlands and in the case
of cultivating between the rows of growing crops the implement can be drawn on
to the roadway or headland clear of the crop and there turned round for the return
journey.
The invention also relates to engines used for steam cultivation in which the
winding drums are horizontal and the rope is coiled mechanically.
In this case the coiling lever is arranged either to guide the rope when passing
direct to the implement in the ordinary way or when the rope is led to the back
of the engine to admit of the implement being pulled even with the engine itself
where it is required.
My invention also relates to the manner of driving the vertical winding drums
on the hind axle separately from the road gear of the engine.

ALFRED GREIG of Leeds in the County of York
APPARATUS FOR STEAM CULTIVATION
"
My invention applies firstly to winding engines used for steam cultivation in
which the winding drums revolve vertically on the hind axle of the engine and
has for its object to improve the coiling or laying of the ropes evenly on these
drums.
To effect this the rope instead of being taken direct off the back of the engine
or carried round a pulley or sheave fixed under the engine direct to the implement
is taken forward to as great a distance as possible from the drum and passed round
a sheave fastened to the front axle or other suitable place at a distance from the
drum it is then passed back and around another sheave fastened to the tank at
the hind end of the engine. By this means sufficient distance is obtained between
the drum and the fixed point from which the rope is guided on to the drum to
allow the rope to coil itself evenly which it will not do when the point at which it
is paid on and off the engine is close to the drum. .
The above arrangement admits of the sheave round which the rope passes to the
implement being placed close to the hind axle and so the tendency of the strain to
turn the engine round is decreased. Also implements for ordinary work can be
pulled level with the engine thus decreasing the width of the headlands and in the
case of cultivating between the rows of growing crops the implement can be drawn
"on to the roadway or headland clear of the crop and there turned round for the
return journey.
:
The invention also relates to engines used for steam cultivation in which the
winding drums are horizontal and the rope is coiled mechanically.
In this case the coiling lever is arranged either to guide the rope when passing
direct to the implement in the ordinary way or when the rope is led to the back of
the engine to admit of the implement being pulled even with the engine itself
where it is required.
My invention also relates to the manner of driving the vertical winding drums
on the bind axle separately from the road gear of the engine.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS
Figure 1 is a side elevation, Figure 2 is a plan and Figure 3 is an end elevation
of a winding engine for steam cultivation constructed in accordance with my
invention.
The winding drum in this engine is mounted vertically upon the axle of the
main road wheels. This winding drum is marked A.
B is a large guide pulley or sheave mounted beneath the axle of the fore wheels
and C is another guide pulley or sheave at the rear end of the engine.
As the Drawing indicates the rope by which the implement is hauled towards
the engine is led around the sheave C then around the sheave B and so to the
winding drum A. The winding rope then will coil itself evenly upon the winding

I also according to my invention employ a guide sheave at the rear of the engine
in the case of hauling engines provided with a winding drum mounted on a vertical
axis beneath the boiler which is a very usual construction.
Figure 4 is an elevation and Figure 5 is a plan of such an engine.
D is the winding drum and Ę is the guide sheave at the rear of the engine. To
admit of the rope being led from the guide sheave to the drum as the drawing
indicates the axle of the main wheel is placed higher than usual to be out of the
way of the rope. Also the coiling gear F, which is otherwise of the ordinary
description, is so arranged as to be capable of working beneath the boiler in the
position in which the Drawing shows it. The coiling gear is also available when
the hauling rope is led direct from the winding drum to the implement in the
manner now usual, and which in some cases may still be convenient.
The guide sheave E at the rear of the engine can be shifted in its bracket so
that its axis may occupy either the position E'. or E². When in the position E²
the hauling rope is intended to be led off in the opposite direction that is to say to
the left instead of the right side of the engine.
In the engine shown by the Figures 1. 2 and 3 also the rope can be led off on
either side of the engine, and this simply by shifting it from one side of the guide
sheave C to the other.
The advantages which this arrangement offers are that the implement can be
drawn further on to the headland than is possible when the winding gear is
arranged so that the rope must be led off from the centre of the engine. Where
this is the case there is danger of the implement coming in collision with the
engine if it be made to approach it at all closely. But when the hauling rope is
led off from the extreme end of the engine, as shewn, the implement may be drawn
up quite close without risk as the engine can be made to move forward out of the
way when the implement advances so far as to overlap the engine. Also by causing
the engine to move forward in this manner when the implement has been drawn
close up the turning of the implement on the headland is much facilitated..
The driving gear of the engine shewn by the Figures 1. 2 and 3 is also a feature
of my invention. Two speeds are obtained by means of two pinions fixed on the
crank shaft and two spur wheels G1 G2 sliding with a feather along the inter-
mediate shaft H. Either one or other of these wheels can be brought into gear
and so two speeds are available in the transmission of the motion from the crank
shaft to the intermediate shaft; and the same change speed gear is applicable both
for the road gear and for the winding gear.
For the road gear there is a pinion I sliding with a feather on the shaft H. and
this pinion by the lever K can be slidden into or out of gear with a spur wheel on
the second intermediate shaft L.
The shaft L also has upon it a toothed pinion which gears with a ring of spur
teeth on the right side of the engine on the axle of the main road wheels.
The movement is transmitted from the intermediate shaft H to the winding
drum by means of a pinion M which is able to slide with a feather on the shaft H.
By means of the hand lever N the pinion M can be put into or out of gear with the
wheel O which turns on a stud axis. This wheel O also gears with a ring of teeth
upon the periphery of the winding drum A.
Having thus described the nature of my invention and the manner of performing
the same I would have it understood that I claim :-
First The arrangement with respect to the winding rope, illustrated by the
Figures 1. 2 and 3 in which the said rope passes first to a guide sheave or pulley
at the rear end of the engine then forward around a second guide sheave or pulley
and so to a vertical winding drum substantially as described.
Second-The arrangement in respect to the winding rope illustrated by the
Figures 4 and 5 in which the said rope comes first to a guide sheave or pulley at
the rear of the engine and then passes to a winding drum upon a vertical axis upon
which it is wound by the aid of coiling gear substantially as described.
Third The arrangement of driving gear illustrated by the Figures 1 2 and 3 in

page_text: which the same change speed gear is available both for the road wheels and the
winding gear; there being an intermediate shaft driven through the change gear
and having upon it two sliding pinions by one of which the intermediate shaft can
be coupled with a train of wheels imparting motion to the road wheels of the
engine and by the other the intermediate shaft can be coupled to another train of
wheels imparting motion to the winding drum substantially as herein described.
In witness whereof I the said Alfred Greig have hereunto set my hand and
seal this Twenty fourth day of January in the year of our Lord One thousand
eight hundred and eighty four.
