PROVISIONAL SPECIFICATION.
Improvements in Traction Engines Fitted with Winding Drums."
We, ROBERT HENRY FOWLER, Engineer, and GEORGE SCHOFIELD TUER,
Draughtsman, both of The Steam Plough Works, Leeds, in the County of York,
do hereby declare the nature of this invention to be as follows:-
This invention relates to engines having a vertical winding drum or drums at
one side.
In such engines as heretofore constructed the drum has been driven by
a pinion on the crank shaft gearing with a ring of teeth on the drum and arranged
so as to be thrown by a suitable clutch into and out of gear.
In such engines since the diameter of the ring of teeth on the drum cannot be
indefinitely increased nor the diameter of the pinion on the crank shaft indefinitely
decreased, it is practically impossible to make the ratio of the speed of the drum
to that of the crank shaft less than a fixed fraction say and this in many cases
is not small enough.
According to this invention we obviate this objection by mounting the pinion
driving the drum on the second motion shaft of the road gear. This renders it
possible by suitably proportioning the pinions to vary the ratio between wide
limits.
We also can by the addition of a clutch on the road motion arrange the gearing
so that the drum can be driven at either of two speeds at the option of the driver
the pinions used for two speeds of the road motion being by this arrangement used
for imparting two speeds to the winding motion also.

Improvements in Traction Engines Fitted with Winding Drums.
We, ROBERT HENRY FOWLER, Engineer, and GEORGE SCHOFIELD TUER,
Draughtsman, both of The Steam Plough Works, Leeds, in the County of York,
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 :-
This invention relates to engines having a vertical winding drum or drums at
one side. In such engines as heretofore constructed the drum has been driven by
a pinion on the crank shaft gearing with a ring of teeth on the drum and arranged
so as to be thrown by a suitable clutch into and out of gear.
In such engines since the diameter of the ring of teeth on the drum cannot be
indefinitely increased nor the diameter of the pinion on the crank shaft indefinitely
decreased it is practically impossible to make the ratio of the speed of the drum to
that of the crank shaft less than a fixed fraction say 16th and this in many cases is
not small enough.

page_text: According to this invention we obviate this objection by mounting the pinion
driving the drum, on the second motion shaft of the road gear. This renders it
possible by suitably proportioning the pinions to vary the ratio between wide
fimits.
We also can by the addition of a clutch on the road motion arrange the gearing
so that the drum can be driven at either of two speeds at the option of the driver,
the pinions used for two speeds of the road motion being by this arrangement used
for imparting two speeds to the winding motion also.
Figure 1 is a side elevation and Figure 2 a plan (both in outline only) of an
engine fitted according to this invention.
Figure 3 is a horizontal section to twice the scale of Figures 1 and 2 of the
gearing.
a is the crauk shaft, b the second motion shaft, c the third motion shaft of the
road gear and d the axles of the road wheels. a' is a pinion fixed to the crank
shaft and as a pinion connected to it by grooves and feathers but capable of being
shifted longitudinally on it by a forked clutch lever (not shown) engaging with
the groove e.
6 is a wheel connected by grooves and feathers with the second
motion shaft b but capable of being shifted longitudinally on it by a forked clutch
lever (not shown) engaging with the groove f. 62 is a double wheel loose upon the
shaft b but capable of being connected to it by the clutch g connected to the shaft
by grooves and feathers and held in place by a pin h. One ring of teeth on this
wheel gears with the pinion a² and the other with the wheel c¹ fixed to the shaft c.
63 is a pinion connected by grooves and feathers with the shaft b and held in place
by the pin j. The pinion gears with a ring of teeth on the winding drum k
which is pivotted on a stud fixed to the side of the boiler. When it is desired to
drive the winding drum k the pinion a¹ is put into gear with the wheel b', the
pinion is put into place and the clutch g is removed after taking out the pin h.
When the road wheels are to be driven at either speed the pin is taken out and
the pinion removed, whilst the clutch is put into place.
For the fast speed the wheel b¹ is put into gear with the pinion a¹ and the
pinion a² is put out of gear whilst for the slow speed the wheel 6 is put out of gear
with the pinion a' and the pinion a² is put into gear with the wheel b³.
Figure 4 is a view similar to Figure 3 and showing a modification by which two
speeds can be given to the winding drum.
In this arrangement the double wheel 62 is replaced by two wheels and m (the
former being free to turn on the boss of the latter) and a clutch n is added to
connect these two wheels together.
The clutches g and n are operated by forked clutch levers.
When the road wheels are to be driven both the clutches g and n are put into
gear and the working for the two speeds is exactly as above described.
When driving the winding drum at either speed the clutch n is out of gear.
For the fast speed the clutch g is also out of gear and the working is as above
described but for the slow speed the wheel 6' is put out of gear with the pinion a',
the pinion a² is put into gear with the wheel m and the clutch g is put into gear.
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. Driving a vertical winding drum at the side of the engine by a pinion on the
second motion shaft of the road gear substantially as described.
2. In arrangements such as are referred to in Claim 1 providing a clutch or
driving pin connecting the second motion shaft with the road gear substantially as
described.
3. In arrangements such as are referred to in Claim I providing on the second
motion shaft two wheels connected together by a clutch one gearing with a pinion
on the crank shaft and the other with a wheel of the road gear substantially as
described.

page_text: 4. Gearing substantially as described and shown at Figures 1 to 3 of the
drawings.
5. Gearing substantially as described and shown at Figure 4 of the drawings.
