Improvements in Fare Indicators for Adjustment to Different
Distance Tariffs:
I, HEINRICH SCHWABACHER of Dessauerstrasse 6; Berlin S.W. in the Empire
of Germany, Manufacturer 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 hitherto known fare indicators with different distance tariffs the measure of
the influence on the indicator and controlling work has been regulated according to
the desired tariff by giving to the driving organ (tappet worm shaft etc.) in
connection with the wheel axle a changeable limit to its movement by means of the
adjustment shaft. In the present arrangement however adjustment for the different
distance tariffs is obtained from a driving organ with always uniform limit of
movement by causing the indicating and controlling work to be operated by an
adjustable intermediate gear corresponding to the desired tariff.
In the annexed drawings this arrangement is shown in three modifications of
construction as fitted to a fare indicator, which is operated by a piston with uniform
stroke in the known manner.
In the arrangement shown in Figs. 1 to 3, the piston a the stroke of which
receives an always equal limit by means of the regulating screw b, operates upon a
double armed lever c, the effective length of which corresponds to the position of
its adjustable fulcrum or suspension point. The lever c is provided with a slot-d
which has several recesses for the pine of the lever the number of which corresponds
to that of the several distance tariffs. The pin e is seated on a carriage connected
with an eccentric rod g and can be brought into three different positions (Fig. 3)
by moving the eccentric by means of the commutating axlei whereby the effective
length of the lever c is correspondingly changed. In order to secure the position of
the lever cat the different positions of the pin e, above the slot d is hinged a bar k
which provided with semicircular holes is always pressed downwards by means of a
spring, but which can give way to the lateral movement of the pin e when
the latter is moved to the left or to the right by means of the turning of the
eccentric h.
In order that on this movement the whole lever system is not carried along, there
is provided a stopping pin m which lies in the slot n of the lever c and which
therefore does not hinder the up and down movement of the latter, but will prevent
a longitudinal movement. Whilst the one end of the lever c is lifted at certain
intervals by the stroke of the piston a, the other end is provided with a dog o
which transfers this temporary movement to the wheel p in connection with the
indicating or controlling work. It is evident that the measure of the influence on
the wheel p depends upon the position of the fulcrum of the lever c and must grow
with the distance of the pin e from the dog o, that is with the increase of the
effective length of the lever arm. Therefore the arrangement can be set so that
the dog o with the position of the pin e shown in the drawing turns the wheel p at
each stroke of the piston a for instance three teeth forwards, whilst in the two other
positions of the pin e the wheel p is turned at each piston stroke the multiple
corresponding to the second and the third tariff.
In the arrangement represented in Figs. 4 and 5 there are provided three
levers c c the fixed fulcra of which are so situated that the effective length of

sponding to the first, second and third tariff. The position a has also here always
an equal stroke and operates according to the situation of the axle i upon the
lever c1 c2 or c 3. The disengaging of the levers c2 and c3 for the first or for the
second tariff is operated by means of two arms r and s provided on the axle i. For
the first tariff the levers 2 and c3 are brought out of action by lifting them by
means of the arm r (Figs. 4 and 5), whilst for the second tariff the lever c3 only is
lifted by the arms and put out of operation. The different amount of operation
of the ratchet wheel p and thus of the indicating or controlling work corresponding
to the different tariffs, is here equally effected by indirectly changed transmission
since the impulsion organ a itself is always equally limited in its movement.
The arrangement shown in Figs. 6 and 7 differs from those before described,
since here the movement of the position a again working with uniform stroke is
always transferred in an unchanged manner to the ratchet wheel p by means of the
. doublearmed lever c. The variability of the influence on the indicating or controlling
work is here effected by means of a toothed wheel u which is arranged to move
endwise upon the ratchet wheel shaft t but turns with the latter. This toothed
wheel is provided on its periphery with three different divisions of teeth which
correspond to the separate tariffs.
According to the larger or smaller number of teeth of that part of the toothed
wheel u which gears with the wheel connected with the indicating and controlling
work, the latter wheel will turn quicker or slower and thus effect an indication
corresponding to the desired tariff. The latéral movement of the wheel u is effected
in the construction illustrated by means of a fork w surrounding this wheel and
pivoted on the pin x the other end y of this fork reaching into a worm a seated upon
the axle i so that by the revolution of the axle i the fork w and the wheel u can be
moved to the left or to the right.
The wheel on the axle i is revolved by successive movements of the setting
handle. At each movement of the latter in one direction the pin thereon
engaging in a recess of the said wheel moves the wheel, with the movement of
the handle.
The handle is then drawn away from the wheel to disengage the pin from the
wheel and it is then moved back to re-engage the pin with the next recess in
the wheel so that the latter may be again moved; a pawl prevents the backward
movement of the wheel.
It may also be mentioned that the means for obtaining changeable influence of
the indicators which means are inserted between the impulsion organ with uniform
stroke and the indicating and controlling work, can be replaced also by others
than the before described means without departing from the characteristic features
of this invention.
Also instead of the piston serving as stroke transmitter there can be of course
used other impulsion organs with equal limit of movement.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In fare indicators adjustable for different distance tariffs and having an
impulsion organ with uniformn stroke :-
i. An adjustable transmission for the impulsion of the indicating and controlling
work, which adjustable transmission is inserted between the latter and the impulsion
organ and regulated by the adjustment shaft.
2. A form of construction of the arrangement described in Claim 1, in which the
impulsion of the indicating and controlling work is operated by a lever c with
displaceable fulcrum e.
3. A form of construction of the arrangement described in Clain 1, in which the
impulsion of the indicating and controlling work is operated by several movable
levers c, c, c, with different fulcra.

page_text: 4. A form of construction of the arrangement described in Claim 1, in which
the impulsion of the indicating and controlling work is operated by means of a
toothed wheel u provided on its periphery with various divisions of teeth.
