PROVISIONAL SPECIFICATION.
An Improved Apparatus for Controlling the Switches of
Tram Lines.
I, EDWARD PENNING DUPUIS, of 31, Merseburgerstrasse Halle a/Salle, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a device for operating the switches of tram rails which
is operated by the driver without stopping or descending from the car.
Immediately under the car is hinged a curved arm which is weighted and is
suspended by a suitable connection and a double eye from a hook or its equivalent
on the car, so that the said curved arm may be fixed in one of two positions with
respect to the rail. In its highest position it is clear of the rail, but in its lowest
position it is adapted as the car moves forward to come into contact with an arm.
fulcrated by a transverse pin to the rail and turn the said arm over when the, end
of the said arm comes into contact with one end of a lever fulcrated below the rail.
and as the wheel of the car moves forward its flange bears on the arm and son
depresses the lever. The other end of the lever is in contact with the arm of a
bell-crank lever, the other arin of which is connected to the switch by a suitable
link so that when the arm is depressed it forces down one end of the lever' and'.
raises its other end which lifts one arm of the bell-crank lever and causes the other'
end thereof to pull the switch over. Suitable springs are employed to restore-the
arm and levers to their normal positions, but to prevent this taking place until the
last wheel of the car has passed the point, suitable pièces are provided between
the wheels which will prevent the arm pivotted to the rail from rising and turning
back over into its normal position.

COMPLETE SPECIFICATION.
An Improved Apparatus for Controlling the Switches of
Tram Lines.
I, EDWARD PENNING DUPUIS of 31, Merseburgerstrasse Halle a/Salle, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention
aud 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 a device for controlling the switches of tram lines which
is operated by the driver without stopping or descending from the car.
In the accompanying drawing which illustrates this invention :-
Figure is a view in side elevation-partly in section,
Figure 2 is a view in plan of the gear, and
Figure 3 is a view in transverse section thereof.
Throughout the views similar parts are marked with like letters of reference.

page_text: Immediately under the body of the car is hinged to a suitable bracket a a curved
arın b which is weighted by a suitable bracket c and is suspended by a suitable
link e having a double eye e¹ from a hook e² or its equivalent on the body of the
car so that the said curved arm may be fixed in one of two positions with respect
to the rail. In its highest position it is clear of the rail, but in its lowest position
as shown by Figure 1 it is adapted as the car moves forward to come into contact
with an arm ffulcrated by a transverse pin in the slot in the rail X and turn the
said arm over so that its end comes into contact with one end g' of a lever 9 fulcrated
longitudinally with and below the rail. As the wheel P of the car moves forward
its flange bears on the arm fand so depresses the end g¹ of the lever g. The other
end of the lever g is in contact with the arm of a bell-crank lever, the other
arm h¹ of which is connected to the switch Z. Thus when the arm f is depressed it
forces down the end g¹ of the lever g and raises its other end g' which lifts the
arm h of the bell-crank lever and causes the end h¹ thereof to pull the switch Z
over. Suitable springs m and n are employed to restore the arm f and the levers g
and h to their normal positions, but to prevent this taking place until the last wheel
of the car has passed the switch, suitable pieces are provided between the wheels
which will prevent the arm f from rising and turning back over into its normal
position until the last wheel of the car is clear of the switch.
It will be seen that with this apparatus the switches can be controlled from the
platforms of the cars both without descending or without stopping.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved apparatus for controlling the switches of tram lines from the
platforms of the cars, substantially as hereinbefore described and illustrated by the
accompanying drawing.
