Improvements in Fare Registering Apparatus for Public Vehicles.
I, FRIEDRICH WILHELM GUSTAV BRUHN, of 104 Friedrichstrasse, Berlin, in the
Empire of Germany, Director, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in devices connected with apparatus for
automatically indicating the fare due on a cab or other public conveyance; said fare-
indicating or registering apparatus being of any construction irrespective of whether
the registration of the fare takes place solely in proportion to the time occupied on
the journey or according to both time and distance. Apparatus of this kind is
particularly described in the Specifications of former British Patents No. 4390 dated
March 23rd 1887, No. 9328 dated June 26th 1888, No. 9461 dated June 18th 1890;
No. 4130 dated March 7th 1891 and No. 3860 dated February 27th 1892.
In the use of such fare-registering apparatus it often happens that it becomes
necessary to stop the action of the same for a certain time, for example, when the
horse falls, in which case the fare indicator should be thrown out of action until
the horse has been got up again; the apparatus should also be stopped during the
time expiring while the passenger is settling the payment of his fare with the driver.
The object of my invention is to meet this requirement and to provide means
whereby the driving mechanism of the fare indicating apparatus can be thrown out
of gear for a certain time during which time the position of the fare indicating
hand or figure remains unchanged. After such lapse of time the driving
mechanism becomes automatically re-engaged and the fare indicator then advances,
as before in the prescribed manner.
is
The characteristic feature of my improved device consists of a segment of a
circle which by a certain movement of a movable mechanism, to which the driver
has access (for example the shaft of the tariff-changing mechanism or the shaft to
which the signalling device, indicating to the public whether the carriage
engaged or disengaged, is connected) is interposed between the fare indicating
shaft and the main actuating part of the fare registering apparatus and must be
moved back by the latter to the initial position before the fare-indicating shaft
can be further acted upon by the driving mechanism. The connection of the
segment with the intermediate mechanism may be effected in different ways.
According to one constructional form of this invention a lever designed to
intermittently actuate through a pawl a wheel connected to the spindle or axis
carrying the hand or hands which indicate on the dial of the fare-registering
apparatus the fare to be paid. The said lever forming a main part in the apparatus
hereinbefore particularly referred to is, in time apparatus caused to oscillate about
its pivot by a clockwork, while in combined time and distance apparatus the said
lever is caused to oscillate by clockwork as well as by a measuring wheel (a wheel
of the cab from which motion is derived for actuating the fare registering
apparatus) through the medium of suitable intermediate mechanism.
When the advancing motion of the hand or hands is required to be stopped for
a certain time the driver turns a shaft which forms the accessible part of the
tariff-changing mechanism or of the signalling device as the case may be, until
an arm or cam thereon disengages a stop lever or pawl-from the teeth of a toothed

page_text: segment which is then moved by a controlling spring against a stop. In this
position of the said segment a branch of the actuating pawl of the oscillating lever
is supported by the segment and cannot be caused by the oscillating lever to engage
with the indicator wheel. The oscillating lever on its next downward oscillation is
therefore unable to actuate the indicator. The downward movement of the oscillating
lever however by means of an adjunct or branch of the pawl which adjunct itself
acts as a pawl causes the said. toothed segment to return towards its former
position to the extent of one tooth. The aforesaid stop lever or pawl which after
having been released by its actuating arm or cam can re-engage the teeth of the
toothed segment arrests the latter in the lowered position, so that each downward
movement of the oscillating lever causes the segment to return by steps towards its
initial position. When the adjunct of the pawl has displaced the last tooth of the
segment the lever is again enabled to produce a downward oscillation to such an
extent that the pawl again engages the indicator wheel, whereby the spindle and
the hand thereon are again actuated.

I, FRIEDRICH WILHELM GUSTAV BRUHN, of 104 Friedrichstrasse, Berlin, in the
Empire of Germany, Director 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 :-
My invention relates to improvements in devices connected with apparatus for
automatically indicating the fare due on a cab or other public conveyance; said
fare-indicating or registering apparatus being of any construction indifferent whether
the registration of the fare takes place solely in proportion to the time occupied on
the journey or according to both time and distance. Apparatus of such kind being
particularly described in the Specifications of British Letters Patent No. 4390 dated
March 23rd 1887, No. 9328 dated June 26th 1888, No. 9461 dated June 18th 1890,
No. 4130 dated March 7th 1891 and No. 3860 dated February 27th 1892.
In the use of such fare-registering apparatus it often happens that it becomes
necessary to stop their action for a certain time, for example, when the horse falls,
in which case the fare indicator should be thrown out of action until the horse
has been got up again; the apparatus should also be stopped during the time expiring
while the passenger is settling the payment of his fare with the driver.
The object of my invention is to meet this requirement and to provide means
whereby the driving mechanism of the fare indicating apparatus can be thrown out
of gear for a certain time during which time the position of the fare indicating
hand or figure remains unchanged. After such lapse of time the driving mechanism
becomes automatically re-engaged and the fare indicator then advances, as before,
in the prescribed manner..
The characteristic feature of my improved device is a segment of a circle which
by a certain movement of a movable mechanism, to which the driver has access (for
example the shaft of the tariff-changing mechanism or the shaft to which the
signalling device, indicating to the public whether the carriage is engaged or
disengaged, is connected) is interposed between the fare indicating shaft and the main
actuating part of the fare registering apparatus and must be moved back by the
latter to the initial position before the fare-indicating shaft can be further acted

page_text: upon by the driving mechanism. The connection of the segment with the
intermediate mechanisms may be effected in different ways.
To make my said invention more clearly understood reference may be taken to.
the accompanying drawing in which, by way of example, my improved device is
diagrammatically shown by Figure 1, in the ordinary position in which the fare.
registering apparatus is in action, and by Figure 2, in the position in which the
driving mechanisms of the fare-registering apparatus are thrown out of gear.
Similar letters refer to similar parts throughout the several views.
In the present example a indicates a lever designed to operate through the
pawl d the intermittently rotating wheel & connected to the spindle or axis e carrying the
hand which indicates the fare to be paid on the dial of the fare registering apparatus. The
said lever a forming a main part in the apparatus hereintofore particularly referred to is,
in time apparatus caused to oscillate about its pivot by a clockwork, while in combined
time and distance apparatus the said lever is caused to oscillate by clockwork as well as by
a measuring wheel (a wheel of the cab from which motion is derived for actuating
the fare registering apparatus) through the medium of suitable intermediate inechanism..
When the advancing motion of the haud or hands is required to be stopped for
a certain time the driver turns the shaft k (forming the accessible part of the tariff-
changing mechanism or of the signalling device as the case may be), until an arm
or cam / thereon disengages the stop lever or pawl from the teeth of the segment f
which is then moved by a controlling spring against a stop i (Figure 2). In this
position of the said segment the branch e of the actuating pawl d of the oscillating
lever a is supported by the segment and therefore, the pawl d cannot he caused
by the lever a to engage with the indicator wheel b. The oscillating lever on its
next downward oscillation is therefore unable to actuate the indicator. The downward
movement of the oscillating lever a however by means of the adjunct or branch e
of the pawl d, which adjunct itself acts as a pawl, causes the toothed segment f to-
return towards its former position to the extent of one tooth. The aforesaid stop.
lever or pawl g which after having been released by its actuating arm or cam can
re-engage the teeth of the segment f arrests the latter in the lowered position, so
that each downward movement of the oscillating lever a causes the segment of to.
return by steps towards its initial position. When the adjunct e of the pawl d has
displaced the last tooth of the seguient the lever a is again enabled to produce a
downward oscillation to such an extent that the pawl d again engages the indicator-
wheel b, whereby the spindle e and the hand thereon is again actuated.
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:-
1. In a fare register, the combination with the indicator ratchet, and its actuating
lever and pawl, of a hand-operated stop adapted to move and hold said pawl out.
of engagement with its ratchet and means for automatically disengaging the stop
from the pawl, for the purpose set forth.
2. In a fare register, the combination with the indicator ratchet, its actuating
lever and pawl, of a band operated stop adapted to move and hold said pawl out.
of engagement with its ratchet without interfering with the oscillations of the lever,.
and means controlled by said oscillations for automatically disengaging the stop..
from the pawl, for the purpose set forth.
3. In a fare register, the combination with the indicator ratchet, its actuating
lever, and a two-armed pawl pivoted thereto, one of said arms normally engaging
said ratchet; of a spring-actuated ratchet stop adapted to be moved by its spring into.
engagement with the second arm of the aforesaid pawl, a spring-actuated locking
lever normally in cgagement with the ratchet stop, and means operated by hand
for moving said locking lever out of engagement with the stop, whereby the latter
is automatically returned into its engagement with its locking lever by the indicator-
ratchet pawl through the oscillations of its lever, for the purpose set forth.

page_text: 4. The combination with the ratchet c, the lever a, and the two-armed pawl d;
of the ratchet segment f, its locking lever g and the cam shaft k, said parts arranged
and operating substantially as and for the purpose set forth.
