PROVISIONAL SPECIFICATION.
Improvements in or connected with Fare Indicators to enable various
Tariffs to be adopted.
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:-
This invention relates to a device applicable to fare indicators for public vehicles
of all kinds, by means of which the indicator may be easily and certainly adjusted
to different tariffs which then correspond to the actual fare circumstances. For
this object the lever operating the pawl of the indicating mechanism is so arranged
that its ratio of transfer may be altered so that the pawl accordingly describes a
longer or shorter course and the ratchet wheel is revolved faster or slower.
The device is operated in the ordinary manner by means of a cam lever which at
each revolution of the wheel which measures the distance, is caused to describe an
up and down movement. The cam of this lever acts on a two-armed lever which
carries at its other end a pawl, operating a ratchet wheel.
The pivot of the two-armed lever is mounted on one end of a pivoted lever so
that by turning the latter lever in the one or the other direction the said pivot may
be adjusted or shifted in a slot formed in the two armed lever so that the leverage
or rate of transfer of the two arms of this lever may be altered and the pawl be
caused to make a correspondingly longer or shorter stroke.
In order to prevent any longitudinal displacement of the two-armed lever it is
pivotally connected at its front end by means of a pin to a second two-armed
lever revoluble on a fixed pivot. The front end of the former lever is therefore
always guided in the same circular are by the latter lever. A pawl is also arranged
on the shorter arm of the latter lever to act on a ratchet wheel. This ratchet wheel
in turn operates a device which indicates the total length of distance traversed by
the vehicle in question.
The movement of the indicating ratchet wheel is transferred to the usual stroke
wheel by means of intermediate gearing, which stroke wheel by means of suitable
mechanism operates the indicator or the figure disc of the fare indicator.
It is thus possible by a simple movement of the adjusting lever to adjust the
apparatus to various tariffs without its being necessary to throw separate
mechanisms in and out of gear.

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:-
-
This invention relates to a device applicable to fare indicators for public vehicles
of all kinds, by means of which the indicator may be easily and certainly adjusted
to different tariffs which then correspond to the actual fare circumstances. For
this object the lever operating the pawl of the indicating mechanism is so arranged
that its ratio of transfer may be altered so that the pawl accordingly describes a
longer or shorter course and the ratchet wheel is revolved faster or slower.
Such an apparatus is shown in the accompanying drawings, Figure 1 being a
side view and Figure 2 a plan view.
The device is operated in the ordinary manner by means of a cam lever D which
at each revolution of the wheel which measures the distance, is caused to describe
an up and down movement. The cam d of this lever acts on a two-armed lever A
which carries at its other end a pawl a pivoted on a spindle a' and operating a
ratchet wheel G.
The pivot a² of the two-armed lever A is mounted on one end of a lever S pivoted
on a bolt s so that by turning the lever S in the one or the other direction the
said pivot a² may be adjusted or shifted in a slot a formed in the two armed
lever A so that the leverage or rate of transfer of the two arms of this lever may
be altered and the pawla be caused to make a correspondingly longer or shorter
stroke.
In order to prevent any longitudinal displacement of the two-armed lever A it
is pivotally connected at its front end by means of a pin a¹ to a second two armed
lever L revoluble on a fixed pivot . The front end of the lever A is therefore
always guided in the same circular arc by the lever L. A pawl is also arranged
on the shorter arm of the lever L to act on a ratchet wheel K. This ratchet wheel
in turn operates a device which indicates the total length of distance traversed by
the vehicle in question.
The movement of the indicating ratchet wheel G is transferred to the usual stroke
wheel H by means of intermediate gearing W, which stroke wheel by means of
suitable mechanism (not shown in the drawing) operates the indicator or the figure
disc of the fare indicator.
It is thus possible by a simple movement of the adjusting lever S to adjust the
apparatus to various tariffs without its being necessary to throw separate
mechanisms in and out of gear.
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. A device applicable for 'fare indicators for indicating different tariffs,
characterized by a lever (S), capable of being adjusted to various positions, being
arranged to carry the pivot (a2) of an intermediate lever (A) operating a pawl (a5)
in such a way that the pivot may be shifted by said lever to alter the ratio of
transfer or leverage of the intermediate lever, thus causing the pawl to describe a
longer or shorter course according to the amount of fare desired, substantially as
hereinbefore described.
2. In the device for fare indicators herein before described, the connection of the

page_text: front end of the intermediate lever (A) with a second lever (L) pivoted on a fixed
pin () in order to prevent the intermediate lever being displaced longitudinally,
substantially as herein before described.
