DAVID GREIG, ALFRED GREIG and RICHARD HOLGATE SHAW all of the Steam
Plough Works Leeds in the County of York "IMPROVEMENTS IN HAULING OR
WINDING ENGINES
"
This Invention relates to improvements in the driving gear of hauling or
winding drums of engines for steam ploughing and other agricultural work
whereby different speeds on the hauling rope can be obtained without the use of
two or more shafts, or the changing of the gearing as is now the practice.
Our improvement: consists in having only one upright shaft for both speeds-at
its top end are two bevil wheels of different diameters either of which can be made
The diameter of the
to gear into one or other of two pinions on the crank shaft.
wheels are so proportioned as to give the necessary speeds required, the pinions
on the crank shaft are keyed on whilst the wheels on the upright shaft are free
to slide into or out of gear with their respective pinions as may, be required. The
smaller bevil wheel is carried by a long boss which can be slidden up or down
upon the vertical shaft. The larger bevil wheel by a boss which is free to slide on
the boss carrying the smaller bevil wheel.
.
The raising or lowering of either one or other of the two bevil wheels so as to
bring it into gear with one or other of the pinions is controlled by levers.
At the bottom end of the upright shaft is a pinion gearing direct into a toothed
wheel on the winding drum.

This Invention relates to improvements in the driving gear of hauling or
winding drums of engines for steam ploughing and other agricultural work
whereby different speeds on the hauling rope can be obtained without the use of
two or more shafts, or the changing of the gearing as is now the practice.
Our improvements consists in having only one upright shaft for both speeds-
at its top end are two bevil wheels of different diameters either of which can be
made to gear into one or other of two pinions on the crank shaft. The diameters
of the wheels are so proportioned as to give the necessary speeds required, the
pinions on the crank shaft are keyed on whilst the wheels on the upright shaft
are free to slide into or out of gear with their respective pinions as may be
required.
The smaller bevil wheel is carried by a long boss which can be slidden up or
down upon the vertical shaft. The larger bevil wheel is carried by a boss which
is free to slide on the boss carrying the smaller bevil wheel.
The raising or lowering of either one or other of the two bevil wheels so as to
bring it into gear with one or other of the pinions on the crank shaft is controlled
- by levers.
At the bottom end of the upright shaft is a pinion gearing direct into a toothed
wheel on the winding drum.
The drawings hereunto annexed shew driving gear arranged as above described.
Figure 1 is a side elevation. Figure 2 a vertical cross section and Figure 3 a
plan view.
A is the ordinary or fast speed pinion fixed on the crank shaft A¹ of the engine.
Bis the wheel into which it gears--the wheel B can be slidden up or down upon the
upright shaft D but is prevented from turning upon it by a feather key or otherwise.
The wheel has a long boss descending from it which can not only turn freely in
the bearing E but can also be moved endwise therein. C is a hand lever coupled
to the lower end of the long boss by means of which the wheel B can be raised or
lowered to put it into or out of gear with the pinion A.
F is the slow speed pinion fixed upon the crank shaft and G is the wheel into
which it gears. The wheel G is free to slide on the boss of the wheel B but is
prevented from turning upon it by a key feather or otherwise. H is a hand lever
by which the wheel G can be raised or lowered to put it into or out of gear with
the pinion F.
Jis a pinion on the lower end of the upright shaft D it gears into a toothed
wheel fast with the winding drum K as seen in Figure 1.
By the above described arrangement of driving gear we are enabled to drive the
winding drum of winding or hauling engines at either one or other of two different
speeds as may be required from one upright shaft instead of employing two or
more shafts as is now sometimes done or if a single shaft only is used instead of
having to take off the bevil gear at the top of such shaft and substitute other
bevil gear for it as is now the case in single speed engines whenever a change of
speed is required on the hauling drum.

page_text: Having thus described the nature of our Invention and the manner of performing
the same we would have it understood that we claim. The combination of driving
gear substantially as herein before described for giving motion to the winding
drum of hauling or winding engines at either one or other of two different speeds
as may be required.
İn witness whereof I the said Alfred Greig have hereunto set my hand and
seal this nineteenth day of November in the year of our Lord One thousand
eight hundred and eighty three.
