Improvements in or connected with Fare Indicators.
I, WILHELM JULIUS GRUBER, of 12, Alvenslebenstrasse, Berlin, in the Empire
of Germany, Chronometer Maker, do hereby declare the nature of this invention
to be as follows:-
In fare indicators, the indicating mechanism is operated by means of a ratchet
mechanism or escapement which is set in motion at each revolution of the carriage
wheel which measures the distance covered. If for each journey a given basis
fare be fixed for a given course or distance, the indicating mechanism for longer
journeys must be thrown out of action until such time as the vehicle has covered a
distance corresponding to the initial basis fare.
In the present invention, the escapement lever operating the indicating
mechanism is for this object brought out of engagement with its ratchet or stroke
wheel by means of a toothed sector until said stroke wheel has completed a rota-
tion corresponding to the basis fare, the toothed sector being also so far revolved
that it releases the escapement lever which then again engages with the stroke
wheel and conveys the movement of the latter to the indicating mechanism.
The operating of the indicating mechanism takes place by means of a ratchet
or stroke wheel which is constantly rotated during the journey and operates an
escapement lever which in turn acts on a vertical lever.
A
The temporary throwing out of gear of the escapement lever is operated by
means of a toothed sector which is revolubly mounted on a pivoted arm.
spring acts on the arm in such a way that in its normal position it bears on a
stop pin, so that the toothed sector is out of engagement with a corresponding
toothed segment on the stroke wheel. The rear end of the sector is formed as a
curved segment which is pressed against a contact pin on the rear arm of the
escapement lever by means of a spring arranged on the pivoted arm.
If the device be in the normal position, the escapement lever is oscillated by
means of the stroke wheel in such a manner that the position of the pivoted arm
and of the toothed sector is thus not altered.
If the device after the completion of the journey is thrown out of action, the
vertical lever is turned so as to act on the spring of the escapement lever, in such
a way that the said lever is pushed backward until its contact pin aforesaid
releases the toothed sector. The latter is consequently turned round by means
of a spring until it encounters a contact pin on the pivoted arm.
In this position
the contact pin of the escapement lever rests on the curved part of the sector and
the escapement lever is out of reach of the stroke wheel.
In setting the machine into a condition for working, the vertical lever on the
contrary is moved in the opposite direction so that by means of the contact pin
of the escapement lever the toothed sector is pushed forward so far against the
action of the spring that it engages with the toothed segment of the stroke wheel.
The escapement lever is in this position, however, still out of reach of the stroke
wheel until, when a distance has been covered corresponding to one of the basis
fares, the stroke wheel has become turned so far back that the curved segment

against the stop pin, whilst the toothed sector is brought out of engagement with
the toothed segment of the stroke wheel, and the escapement lever is brought again
within reach of the stroke wheel so that the indicating mechanism is operated
in the normal manner.

I, WILHELM JULIUS GRUBER, of 12, Alvenslebenstrasse, Berlin, in the Empire
of Germany, Chronometer Maker, 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:-
In fare indicators, the indicating mechanism is operated by means of a ratchet
mechanism or escapement which is set in motion at each revolution of the carriage
wheel which measures the distance covered. If for each journey a given basis
fare be fixed for a given course or distance, the indicating mechanism for longer
journeys must be thrown out of action until such time as the vehicle has covered
a distance corresponding to the initial basis fare.
In the present invention the escapement lever operating the indicating
mechanism is for this object brought out of engagement with its ratchet or stroke
wheel by means of a toothed sector until said stroke wheel has completed a rota-
tion corresponding to the basis fare, the toothed sector being also so far revolved
that it releases the escapement lever which then again engages with the stroke
wheel and conveys the movement of the latter to the indicating mechanism.
Such an arrangement is shown in the accompanying drawings,
Figure 1 being the position in which the indicating mechanism is thrown out of
action at the commencement of a journey;
Figure 2 shows the arrangement of the apparatus on a long journey when the
basis fare has already been exceeded;
Figure 3 shows an end view of the apparatus.
The operating of the indicating mechanism takes place by means of a ratchet
or stroke wheel H which is constantly rotated during the journey and operates
an escapement lever V which in turn acts on a vertical lever Ü.
The temporary throwing out of gear of the escapement lever V is operated by
means of a toothed sector Z which is revolubly mounted on an arm R pivoted on
a pin by means of a pin z. A spring 2 acts on the arm R in such a way that
in its normal position it bears on a stop pin ³, Figure 2, so that the toothed sector Z
is out of engagement with a corresponding toothed segment h on the stroke
wheel H. The rear end of the sector Z is formed as a curved segment z² which is
pressed against a contact pin on the rear arm of the escapement lever V by
means of a spring arranged on the pivoted arm R.
If the device be in the normal position shown in Figure 2, the escapement
lever Vis oscillated by means of the stroke wheel H whilst the pin is pushed
forward to the position shown in dotted lines. The position of the pivoted
arm R and of the toothed sector Z is thus not altered.
If the device after the completion of the journey is thrown out of action, the
vertical lever is turned in the direction indicated by the arrow in Figure 3 so
as to act on the spring of the escapement lever V pivoted on a pin
in such a

page_text: way that the said lever is pushed backward until its contact pin releases the
toothed sector Z. The latter is consequently turned round by means of the
spring in the direction indicated by the arrow in Figure 2 until it encounters a
contact pin on the pivoted arm R. In this position the contact pin v of the
escapement lever V rests on the curved part of the sector and the escapement
lever is out of reach of the stroke wheel H.
In setting the machine into a condition for working, the vertical lever U on the
contrary is moved in the opposite direction so that by means of the contact pin v
of the escapement lever the toothed sector Z is pushed forward so far against the
action of the spring 2 that it engages with the toothed segment h of the stroke
wheel H. The escapement lever V is in this position however still out of reach
of the stroke wheel H, until, when a distance has been covered corresponding to
one of the basis fares, the stroke wheel H has become turned so far that the curved

segment of the toothed sector Z releases the contact pin vs.
then again rests against the stop pin 3, whilst the toothed sector Z is brought
out of engagement with the toothed segment h of the stroke wheel, and the escape-
ment lever V is brought again within reach of the stroke wheel H so that the
indicating mechanism is operated in the normal manner.
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:―
In fare indicators, a device for adjusting the basis fare, which consists of a
toothed sector (Z) mounted on an arm (R), which sector is adapted on the apparatus
being thrown into gear, to bring an escapement lever (V) out of engagement with
a stroke wheel (H) and to be itself brought into engagement with a toothed
segment (h) on said stroke wheel, in such a way that, after a rotation of the stroke
wheel which corresponds to the distance on which the basis fare is arranged or is
based, said sector releases the escapement lever so that the latter engages with the
stroke wheel, whilst the toothed sector itself is brought out of engagement with
the toothed segment (h) of the stroke wheel, substantially as herein before
described.
