page_text: Improvements in Traction Engines fitted with Winding Drums.
We, ROBERT HENRY FOWLER, Engineer, and GEORGE SCHOFIELD TUER, Draughts-
both of the Steam Plough Works, Leeds, in the County of York, do hereby
declare the nature of this invention to be as follows:-
inan,
This invention relates to traction engines fitted with winding drums in which
either the engine or the winding mechanism have two speeds as for example in the
Specification of the Patent granted to us No. 23422 of 1895.
According to this invention means are provided to render it impossible for the
driver to put both travelling speeds or both winding speeds into gear at once, but
allows him to put the fast or slow winding gear into action at the same time as the
slow speed road gear.
For putting the pinions on the motion shafts into and out of action we employ
levers either operating clutches or sliding the pinions on the shafts to put them in
and out of gear.
In an engine similar to the one described in the above mentioned specification we
provide four clutch levers and to two of these we attach catch bars which rest one on
the other the lower one being supported by a fixed abutment. Above this abutment
is another of the clutch levers. On the upper catch bar is a hook which retains
the last mentioned clutch lever, when this lever is in certain positions relatively
to the others.
On the underside of the lower catch bar is an incline, which in one position of the
clutch lever engages with the side of the abutment and in the other rides onto the
abutment and so raises the upper catch bar.
In one position the clutch lever attached to the lower catch bar is locked by the
clutch lever above the fixed abutment which prevents either of the catch bars rising.
Again when the clutch lever attached to the lower catch bar has been moved so that
the incline has ridden up the fixed abutment, the clutch lever above the abutment is
retained by the hook on the upper catch bar and is thus locked with regard to the
clutch lever attached to this bar.

winding Drums.
We, ROBERT HENRY FOWLER, Engineer, and GEORGE SCHOFIELD TUER, Draughts-
man, 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 per-
formed to be particularly described, and ascertained in and by the following
statement:-
This invention relates to traction engines fitted with winding drums in which

Specification of the Patent granted to us No. 23422 of 1895.
According to this invention means are provided to render it impossible for the
driver to put both travelling speeds or both winding speeds into gear at once, but
allows him to put the fast or slow winding gear into action at the same time as the
slow speed road gear.
For putting the pinions on the motion shafts into and out of action we employ

that the incline has ridden up the fixed abutment, the clutch lever above the
abutment is retained by the hook on the upper catch bar and is thus locked with
regard to the clutch lever attached to this bar.

of the engine showing the position of the gearing.
Figure 2 is a diagrammatic side elevation of the gearing only.
Figures 3 and 4 are sections on the lines 3-3 and 4-4 Figures 1 and 2.
Figure 5 is a plan, and Figures 6, 7 and 8 are diagrams showing the different
positions of the levers.
In Figures 1 to 4 the levers are omitted.
a is the crank shaft, the second motion shaft, and e the third motion shaft. dis
a winding drum mounted on a stud at the side of the boiler, and e e are the road
wheels. a is a pinion fixed to the crank shaft and a² a pinion connected to it by
grooves and feathers but capable of being shifted longitudinally on it by a clutch
fork engaging with the groove a" in it.
b is a pinion connected to the shaft 6 by grooves and feathers. When the engine
is being used for winding, the pinion is in gear with a ring of teeth d on the
drum & but when the engine is moved from place to place it may be removed from
the shaft. is a wheel connected to the shaft b by grooves and feathers but capable
of being shifted longitudinally on it by a clutch fork engaging with the groove 63 in
it. b is a wheel fixed to a sleeve free to turn on the shaft b unless it is connected
to it by the clutch which is caused to slide to and fro on the shaft by a clutch fork
engaging with the groove b in it the clutch being connected to the shaft by grooves

hand (Figure 3) or in gear position. 68 is a pinion connected to the boss of the
wheel b and moved to and fro on it by a clutch fork engaging with the groove 6º so
putting the pinion into and out of gear with the wheel c₁ on the shaft c.

ffff Figure 5 are the forks engaging with the grooves a3b3b7 and 69 respec-
tively they are carried by. stems FF F2 F3 working in slotted tubes fixed to the
bearings. 2 g³ are pins fixed to the stems F F F F and protruding through
the slots engage with holes in the clutch levers hk and are locking
bars pivotted respectively to the levers h¹ and h².
For slow speed travelling the pinion a² is in gear with the wheel and the
pinion 68 with the wheel c whilst the pinion b and clutch 66 are out of gear.
For fast speed travelling the pinions 6 and 68 and the clutch 6 are in gear and the
pinion is out of gear.
For slow speed winding the pinions a² and b and clutch are in gear and the
wheel 62 and pinion 6s out of gear.
For fast speed winding the pinion 61 and wheel 62 are in gear and the clutch 60 and
pinion are out of gear.
Figures 6, 7 and 8 show how it is impossible for the driver to put both travelling
speeds or both ploughing speeds into gear at once, but allows him to put the fast
speed or slow speed ploughing gear into gear at the same time as the slow speed
road gear.
When lever his out of gear, Figure 6, the rod k is free to move backwards and
forwards under lever h, therefore the levers and h¹ can be put into and out of gear,
but if he is in gear at the same time as h¹, as in Figure 7, the rod is raised and
prevents the lever h being put into gear, but if lever is in gear at the same time as
lever h, as in Figure 8, the rod is again raised and prevents being put into gear,
but if h and h¹ are both in gear the rod ¹ is pressed down and prevents he being put
into gear as in Figure 6.
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. In a traction engine, the combination of road wheels, a winding drum, means
for driving the wheels and the drum each at two different speeds and means whereby
the driver is prevented from putting both travelling speeds or both winding speeds
into gear at the same time.
2. In a traction engine, the combination of road wheels, a winding drum, means for
driving the wheels and the drum each at two different speeds, four clutch levers
operating the gearing, a locking bar moved by the first lever and carrying a hook
engaging with the second lever, a second locking bar moved by the third lever and
carrying a projection coming between the first bar and a fixed abutment.
3. Locking gear for traction engines substantially as described and shown in the
drawings.
