IMPROVEMENTS IN
This Invention has for its object improvements in winding engines for steam
ploughing and other uses.
The general arrangement of the road or travelling gear of my improved winding
engine is similar to that of traction and winding engines now in use, the main
axle is immediately behind the fire box and it has upon it two spur wheels one on
either side, with which pinions on a counter shaft engage.
I make use of these spur wheels to drive the winding drums. The winding
drums are provided with toothed rings or flanges to engage with the spur wheels
on the main axle, this gear being suitable for driving the winding drums, at the
speeds suitable for ploughing and cultivating.
The winding drums are behind the main axle they are mounted upon eccentrics
carried upon the sides of the tank.
A cast iron tube goes from side to side of the tank and in this is fitted a plain
round bar or axis and upon this are the eccentrics on which the druins revolve.
The eccentrics are secured on this bar by a collar and pin at each end; by removing
these the rod may be drawn out and the druins taken off when the engine is
needed for other work than ploughing or winding.
An arm is carried up from each eccentric; by which it can be turned round
upon its bar or axis and when the eccentric is put over and secured in the forward
position the teeth on the drum engage with those of the spur wheel on the
main axle.
The winding drums are controlled by brake blocks mounted on levers and by
the action of a spring or weight the brake is kept constantly applied while the

page_text: drums are out of gear with the driving mechanism. As the eccentric is thrown
into its forward position the brake block remains in contact with the drum till
after the teeth have began to engage but before the drum reaches its final position
the brake is taken off by the lever coming in contact with a pin fixed on the side
of the tank. When the drum is thrown out of gear the brake is gradually applied
and is full on before the teeth disengage, so that the drum is at all times under
control.
The spur wheels on the main axle are mounted loose so as to be applicable either
for winding or for driving the road wheels when travelling pins being then inserted
connecting the road wheels and the spur wheels.
One of the road wheels is keyed on the axle so that the axle revolves with the
road wheels when travelling but remains fixed when winding.
Rope pulleys are fixed under the boiler on different levels to allow the ropes to
be led off at right angles to the engine on either or both sides. They can be slid
along the bar to which they are attached and can be turned lengthwise of the
engine so as to be clear of the road wheels when travelling.
When the guide pulleys placed underneath the engine are near the fore end of
the boiler and the strain is on the broadside there is a tendency to slew the
engine. To resist this I fix upon the wheels discs or by preference segments of
discs. They are fixed by clips or pins and by cutting into the land afford the
resistance required.

THOMAS PERKINS of Hitchin in the County of Hertford "IMPROVEMENTS IN
WINDING ENGINES FOR STEAM PLOUGHING AND OTHER USES
"
This invention has for its object improvements in winding engines for steam
ploughing and other uses.
The general arrangement of the road or travelling gear of my improved winding
engine is similar to that of traction and winding engines now in use, the main
axle is immediately behind the fire box and it has upon it two spur wheels, one on
either side, with which pinions on a countershaft engage.
I make use of these spur wheels to drive the winding drums. The winding
drums are provided with toothed rings or flanges to engage with the spur wheels
on the main axle this gear being suitable for driving the winding drums at the
speeds suitable for ploughing and cultivating.
The winding drums are behind the main axle, they are mounted upon eccentrics
carried upon the sides of the tank.
A cast iron tube goes from side to side of the tank and in this is fitted a plain
round bar or axis and upon this are the eccentrics on which the drums revolve.

page_text: The eccentrics are secured on this bar by a collar and pin at each end; by removing
these the rod may be drawn out and the drums taken off when the engine is
needed for other work than ploughing or winding.
An arm is carried up from each eccentric, by which it can be turned round
upon its bar or axis and when the eccentric is put over and secured in the forward
position the teeth on the drum engage with those of the spur wheel on the
main axle.
The winding drums are controlled by brake blocks mounted on levers and by
the action of a spring or weight the brake is kept constantly applied while the
drums are out of gear with the driving mechanism. As the eccentric is thrown
into its forward position the brake block remains in contact with the drum till
after the teeth have begun to engage but before the drum reaches its final position
the brake is taken off by the lever coming in contact with a pin fixed on the side
of the tank. When the drum is thrown out of gear the brake is gradually applied
and is full on before the teeth disengage so that the drum is at all times under
control.
The spur wheels on the main axle are mounted loose so as to be applicable either
for winding or for driving the road wheels when travelling pins being then inserted
connecting the road wheels and the spur wheels.
One of the road wheels is keyed on the axle so that the axle revolves with the
road wheels when travelling but remains fixed when winding.
In order that my 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 view of an engine constructed according to this invention.
Figure 2 is a plan. Figure 3 a vertical section through the main axle and Figure 4
a vertical section through the axis of the winding druins.
a is the main axle immediately behind the fire box, it has upon it two spur
wheels b b one on either side, these gear with pinions c c upon the countershaft d.
e e are the winding drums they are provided with toothed rings or flanges e¹ e¹
which when they engage with the spur wheels bb drive the winding drums.
The spur wheels on the main axle are mounted loose so as to be applicable
either for winding or for driving the road wheels when travelling, pins being then
inserted connecting the road wheels and the spur wheels.
A cast iron tube f goes from side to side of the tank and in this is fitted the
axis f. Eccentrics f₁₁ f" are secured on this axis by collars and pins.
The winding drums e e are mounted on these eccentrics. Arms g g are carried
up from the eccentrics by which they can be turned round upon the axis f'
so as to put the toothed rings e¹ e' into gear with the spur wheels 6b on the
main axle.
hh are the levers carrying the brake blocks which are inside the drums and
control them and h¹ h¹ are springs which keep the brakes applied when the drums
are not in gear with the pinions on the main axle. When the arms g g are pulled
over the brake blocks remain in contact with the drums until pins "h" on the
sides of the tank stop the brake levers h h and as the drums continue to move,
the brakes are taken off this occuring just after the teeth on the drums have
begun to engage with the spur wheels b b. Similarly the brakes come into
action just before the drums are thrown out of gear, so that the drums are at all
times under control.-This part of the invention is illustrated by the diagram
view Figure 5.
On Sheet 2 of the drawings is shown an arrangement by which the drums are
driven by 2nd motion wheels on the countershaft instead of being driven by the
spur wheels on the road wheel shaft.
The main gear pinion A is not keyed, but is loose on the boss of the 2nd motion
wheel B, it is provided with two recesses C on the back of the clutch to drive it.

page_text: The clutch D is not keyed on the shaft but revolves loose on the outside of the
2nd motion shaft bracket E and the jaws d of the clutch pass through two spaces F
in the 2nd motion wheel B and into the recesses C in back of the pinion thus the
whole is driven without keys, the 2nd motion wheel B is keyed on the shaft so as
to impart motion to left hand drum through the wheel B¹.
In this arrangement the gear for driving the road wheels is down one side of
the engine only. At the other end of the 2nd motion shaft a wheel the same size
as the 2nd motion wheel is keyed to drive the left hand drum.
The main driving
pinion A is out of gear when ploughing and allows the 2nd notion shaft to revolve
without driving the main road gear. There is no pin to take out when starting
to plough, the clutch D has simply to be slid out of the back of the pinion A.
Having thus described the nature of my said invention and the manner of
performing the same I would have it understood that what I claim is:-
First. Mounting the winding drums so that they can be driven from the
ordinary gearing of the engine without any additional gearing substantially as
described.
Second. Mounting the winding drums on eccentrics at the sides of the tank so
that toothed rings upon them can be thrown into gear with toothed wheels on
the main axle substantially as described with reference to Sheet 1 of the
drawings.
Third. Mounting the winding drums on eccentrics at the sides of the tank so
that toothed rings upon them can be thrown into gear with the 2nd motion spur
wheels substantially as described with reference to Sheet 2 of the drawings.
Fourth. Mounting the spur wheels on the main axle loose so that they may be
applicable either for winding or for driving the road wheels substantially as
described.
Fifth. Arranging the brakes for the winding drums in such manner that they
are automatically kept on so long as the drums are out of gear and are taken off
when the drums are put into gear substantially as described.
Sixth. The arrangement of clutch substantially as shown on Sheet 2 of the
drawings.
In witness whereof I the said Thomas Perkins have hereunto set my hand
and seal this sixth day of November in the year of our Lord One thousand
eight hundred and eighty two
