Improvements in and relating to Fare-indicators.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents
45 Southampton Buildings in the County of Middlesex do hereby declare the nature
of this invention to be as follows:-
This invention has for its object to effectually obviate the fraudulent interference
with fare-indicators of any construction used in public vehicles by connecting the
fare-indicator with suitable safety-devices which indicate in an easily recognizable
manner from the outside whether the fare-indicator is in or out of action or whether
the vehicle is free for service or let, and to what rate of fare the apparatus has in
each case been adjusted by the driver. These devices, like the fare-indicator, are
not accessible to the passenger.
On one side of the fare-indicator proper, which may for instance be actuated
from a wheel nave, is arranged a device for controlling the engagement of the
indicator, and on the other side of the latter a mechanism for adjusting the
apparatus to various fares, and also a device for registering the distance passed
over, which is likewise actuated by the wheel nave, these devices being provided
in a closed casing so arranged in the carriage that it will always be in the sight of
the passenger, for example at the rear of the driver's seat.
For rendering the mode of operation of the several mechanisms better under-
stood will describe one of the well-known apparatus for indicating the fare
according to time and distance which according to circumstances may be actuated
either by means of a clockwork or from a wheel nave or wheel axle.
The operation from the wheel nave is preferably effected by pneumatic means, in
the present example through the agency of an eccentric arranged on the nave,
which in every revolution of the wheel acts, through the medium of a stamp
adapted to be drawn back by a spring, upon an indiarubber ball or bag so as to
compress the same. The pressure exerted upon this ball or bag is transmitted
through a thin pipe to a second indiarubber ball or bag provided within the closed
casing, and is thence communicated to a lever arranged on the fare-indicator.
Proportionately to the greater or smaller angle of oscillation of this lever the
mechanisms of the fare-indicator proper are then actuated in various degrees in the
well-known manner so that this indicator, according as the movement of the said
lever is limited, will advance with more or less speed and will therefore indicate a
higher or lower fare.
This object may be realized by means of a lever secured upon the axis of the
above-mentioned lever and acted upon by the spring, which strikes with a pin
extending through a slot in the front plate against a stepped bar adapted to be dis-
placed over the slot and acted upon by a spring, this bar, conformably to the
position of a disc provided with pins being adjusted by a bell-crank lever in such a
manner that the oscillation of a ratchet lever will be more or less limited according
as the piu strikes against one or the other step of the bar hereinbefore referred to.
By this means the advance of a ratchet wheel actuating the fare-indicator
through the medium of the said ratchet lever and a pawl from the wheel nave will
be retarded or accelerated according as a lever rests upon the nave of the above-
mentioned disc or upon one or the other of the pins placed at unequal distances
from the centre of rotation. In conformity with this the position of the disc
requires to be changed, but the passenger must be precluded from effecting the

page_text: change, and the driver allowed to do this only in the sight of the passenger with
the aid of a key made of special shape. To obviate fraud the position of the disc
must also admit of being at any time inspected by the passenger, for which purpose
upon the axis of the disc is fixed a disc having various colours or bearing suitable
inscriptions, which, when the key is inserted turns with the disc behind the cover
plate of the closed casing, so that through an aperture in the cover plate the rate
according to which the fare-indicator is actuated may always be observed.
The fare-indicator proper may be put in and out of action, that is to say con-
nected with the mechanism actuated by a clockwork or by a carriage wheel, in the
well-known manner by raising or lowering a slide. But to effectually prevent this
slide and consequently the hand being tampered with the device for imparting suit-
able movement to the slide is constructed as follows:-
Beside the fare-indicator upon a plate in the interior of the casing is arranged an
arm adapted to turn upon a fulcrum in such a manner that its fre end comes within
reach of the slide and that under the action of a spring applied to the said slide it
will continually bear against an eccentric adapted to turn with the axis. The
throw of the eccentric corresponds to the movement of the slide necessary for
putting the fare-indicator in and out of action. Upon the axis is moreover placed
a ratchet wheel which through the medium of the pawl permits the eccentric to
turn only in one definite direction. By reason of this arrangement the slide can
never return to the original position before it has completed the movement once
commenced, it being allowed to return only when the mechanism for actuating the
fare-indicator has first been put either in or out of action so as to be seen from
the outside. Now if, as in most cases, the fare-indicator is so arranged that in
the lifting of the said slide the hand moves to the position of zero, but that each
double movement of the slide causes the advance of a counter to an extent corre-
sponding to the minimum fare, a guarantee is obtained that the passenger must
actually be conveyed a distance or a time corresponding to this minimum fare
before the band is capable of advancing. The frauds which have hitherto been
practised on the passenger during the stoppage by the driver moving the actuating
slide are obviated in this arrangement, the more so because the apparatus is set in
action by means of a special key in the sight of the passenger.
The eccentric is turned through the medium of the double key having an
extremity which may be made of various shapes and connected with the key tube,
the said extremity being made to fit the journal of the aforesaid axis. Now, to
prevent the said eccentric being turned too far so that the slide after its arrival in
one or the other extreme position would commence its return movement too soon,
at one extremity of the key is provided a bit, and around the journal of the said
axis a bridge-piece forming the key plate which has suitable apertures at
diametrically opposite points, and below this bridge-piece upon a plate a stop.
By reason of this arrangement a turning movement of the eccentric can take
place only when the bit is inserted into one of the apertures in the bridge-piece.
Exactly after half a revolution of the eccentric and key the bit strikes against the
aforesaid stop and is then opposite the other aperture. In this position a turning
movement of the key in one or the other direction is not possible at all, unless the
key is first drawn from the key hole and inserted again so that the bit enters one
of the apertures. Therefore the slide can be moved from one to the other terminal
position only when the fare-indicator is put in and out of action, and it is rendered
impossible to place the slide during the journey in an intermediate position for
causing an incorrect operation of the fare-indicator. This would at once be
recognized by the passenger or the superintendent as the key would stick in its
place.
For further increasing the safety and control, upon the axis carrying the above-
mentioned eccentric and ratchet wheel is secured a second larger eccentric which
can effect the displacement of a bar, placed at a right angle to the axis, only in
one direction, and which is provided at its front surface with a projection serving
as a stop. This stop is so arranged that in one position of the first eccentric and

page_text: a disengaging lever it bears upon a nose on a second bar placed parallel with the
slide which has the effect that the eccentric, the disengaging lever and the slide of
the fare-indicator cannot be moved further, unless the second bar has been slid
inwards by a signalling device accessible from the outside, to such an extent that
its nose is moved out of the path of the above-mentioned projection. The two
bars are connected with each other by a spring in such a manner that one of them
is continually forced against the eccentric whilst the other in the position of rest is
drawn back so far that its nose must meet with the projection in the turning
movement of the eccentrics.
The displacement of the nose on the second bar from the path of the projection
takes place in a suitable manner by means of a cam placed in the interior of the
casing, which is arranged upon the rotary axis of a signalling device which under
certain conditions can be turned from the outside. The signalling device may
consist of an arm carrying a plate or a flag with a suitable inscription, which when
turned through the medium of the said rotary axis and cam causes the second bar
to be moved forward until a lateral pawl under the action of a spring drops into a
suitable notch in the second bar in order to keep the same against the tendency of
a spring in such a position that the projection on the above-mentioned eccentric
cannot come within the reach of the nose on the second bar. It is only then that
the eccentric can be turned with the right key introduced through the key plate,
and that by raising the slide the fare-indicator can be put out of action. In this
turning movement of the shaft effected by the key the eccentric, which has a lead
of an angle of 90 degrees relatively to the other eccentric, forces the first bar back,
causing it to act by means of the pin, carrying a spring and extending through the
guide slot in the second bar against the rising edge of a plate connected with the
lateral pawl, thereby disengaging this pawl at the proper moment from the second
bar (acted upon by the spring which has meanwhile been put under tension).
this position of the eccentric the rear end of the first bar is in the path of the cam
hereinbefore mentioned so that the latter, or the signalling device is prevented from
turning further.
In
The signalling arm placed in the upright position and the flag or plate of which
serves to show outside that the vehicle is free for use or on its home journey, or
although unoccupied is otherwise let, can therefore be moved to the lower position,
which indicates that the carriage is occupied only after the two eccentrics have
been turned through 180 degrees and the fare-indicator has again been properly
put . action. In this turning movement of the shaft with the two eccentrics the
projection on one of the latter strikes once more against the nose on the second bar
released as described by the said pin so that it is not possible to turn the eccentric
further or disengage the fare-indicator until by the movement of the signalling
arm and flag to the position corresponding to "unoccupied "the second bar is
caused by a part on the cam to advance so as to bring the nose on this second
bar out of the path of the projection on one of the eccentrics and stop it by the
pawl.
The operation of this safety device for putting the fare-indicator in and out of
action is as follows:
Suppose the vehicle to be unoccupied, the fare-indicator out of action and the
signalling arm in the corresponding upright position. In this position the arm is
blocked on the one hand by the rear end of the first bar and on the other hand by
a bent piece arranged outside and serving as a stop, whereas the aforesaid pawl is
disengaged from the second bar by a pin and the nose on the second bar is in the
path of the projection on one of the eccentrics. This however is still in such a
position that the two eccentrics can be turned through 180 degrees before the
projection on one of the eccentrics meets the nose on the second bar.
Now if on a passenger entering the vehicle the fare-indicator is to be put in
action and the signalling arm is to be lowered the key carried about by the driver
must in the sight of the passenger be inserted with the bit into one of the apertures
in the key plate and turned through 180 degrees, as only then the said cam is

page_text: released by the first bar and the lowering of the signalling arm becomes possible.
In the lowering of the signalling arm the cam causes the second bar to advance,
whereby the projection on one of the eccentrics is released again from the nose on
the second bar, so that this nose after the completion of the journey enables the two
eccentrics to be turned further, but not the first bar which in this turning move-
ment is forced against the lateral surface of the cam and thus checks the movement.
Accordingly the signalling arm must in any case first be put upright or in the
position in which it indicates that the vehicle is not used, before the disengagement
of the fare-indicator by the continued turning of the eccentrics becomes possible.
In this movement the first bar as already stated, is so displaced that it blocks the
signalling arm in the position occupied, whilst the second bar is released, so that
the operation of the signalling arm depends upon the fare-indicator being previously
put in action and vice versa, and the disengagement of the latter again on the
previous upward movement of the signalling arm to the position corresponding to
unoccupied," thus effectually obviating the fraudulent operation of the fare-
indicator, because this would be possible only in the sight of the passenger or the
superintendent.
Accordingly the more or less imperfect safety devices heretofore provided in
connection with the well-known fare-indicators themselves and used for a similar
purpose are render superfluous.
From the foregoing description it will be seen that a to-and-fro movement of
the first bar causes the fare-indicator to be put once in and out of action, and
thus corresponds to a complete journey, therefore the movement of the said bar
may advantageously be transmitted to a counter which serves for controlling the
number of the several journeys. For this purpose it is expedient to make the
pin connected with the first bar and carrying a spring in the form of a pawl
which in the displacement of the said bar engages with a ratchet wheel arrested
by a pawl, and thus causes this wheel to turn by steps. Upon the axis of this
ratchet wheel may then for instance be placed a disc which, provided with a
suitable succession of figures, indicates through an aperture in the cover plate of
the casing the number of journeys made by the vehicle.
In cases where it is desired to obtain an indication of the distance passed over
by the vehicle either during a single journey or altogether it is expedient to
provide within the closed casing a suitable registering device, which consists of
a counter constructed in the well-known ranner, and to actuate the same by a
lever. The latter then imparts its movement obtained from the wheel of the
vehicle directly to an arm of the counter which indicates the corresponding
distance through a suitable aperture in the cover plate of the casing.

COMPLETE SPECIFICATION.
Improvements in and relating to Fare-indicators.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 has for its object to effectually obviate the fraudulent interference
with fare-indicators of any construction used in public vehicles, by connecting the
fare-indicator with suitable safety-devices which indicate in an easily recognizable
manner from the outside, whether the fare-indicator is in or out of action, whether
the vehicle is on hire or not and to what rate of fare the apparatus has in each

page_text: case been adjusted by the driver. These devices like the fare indicator, are not
accessible to the passenger.
These objects are attained by the mechanism illustrated in the accompanying
drawings in which,―
Figure 1 is a side view of a cab provided with this invention.
Figure 2 a cross section of the driver's seat at the rear of which the casing of
the fare-indicator and the safety devices are received;
Figure 3 a front view of said casing respectively, a rear view of the
driver's seat.
Figures 4 to 7 represent detail mechanism for transmitting the work of a cab-
wheel upon the fare indicator, and
Figures 8 to 15 show the safety devices combined, with a fare indicator of known
construction in different positions of the mechanisms.
Similar letters refer to similar parts throughout the drawings.
As represented in the drawings, on one side of the fare indicator proper A, which
may for instance be actuated from a wheel nave, is arranged a device B for con-
trolling the engagement and disengagement of the indicator, and on the other side
of the latter a mechanism C, for adjusting the apparatus to various fares, and also
a device D for registering the distance passed over, which is likewise actuated by
the wheel nave, these devices being provided in a closed casing E so arranged in
the carriage that it will always be within sight of the passenger, for example
at the rear of the driver's seat (Figures 1 to 3).
For rendering the mode of operation of the several mechanisms better under-
stood, one of the well known apparatus for indicating the fare according to time
and distance which, according to circumstances, may be actuated either by means
of a clockwork or from a wheel-nave or wheel-axle, is represented in the accom-
panying drawing.
The operation from the wheel nave is preferably effected by pneumatic means
as in the present example through the agency of an eccentric or cam arranged on
the nave which in every revolution of the wheel, acts through the medium of a
stamp adapted to be drawn back by a spring, upon an india rubber ball or bag c
or any equivalent device, so as to compress the air contained in the same (Figures 4
to 7). The pressure thus exerted upon the enclosed air is transmitted through a
small pipe b to a second india-rubber ball or bag a (Figure 13) or like device pro-
vided within the closed casing E, and is thence communicated to a lever g arranged
on the fare indicator.
!!
In proportion to the greater or smaller angle of oscillation of this lever the
gearing of the fare-indicator proper is then actuated in various degrees in the
well known manner so that the pointer of the said indicator, according as the move-
ment of the lever g is graduated will advance with more or less speed and will
therefore indicate a higher or lower fare.
In the fare indicator represented this object is attained by means of a lever g¹
(Figure 9) secured upon the axis of the lever and acted upon by the spring g³,
which strikes with a pin g' extending through a slot 9 in the front plate a* against
a stepped bar 3 adapted to pass over the slot and acted upon by the spring,
this bar, in accordance with the position of a disc i provided with pins, being
adjusted by a bell-crank lever in such a manner, that the oscillation of the
lever will be more or less limited according as the pin g² strikes against one or
the other step of the bar g³.
By this means the advance of the ratchet wheel 98 (Figure 9) actuating the fare-
indicator through the medium of the lever g' and pawl g' from the wheel nave will
be retarded or accelerated according as the lever h rests upon the nave of the disci
or upon one or the other of the pins, placed at unequal distances from the
centre of rotation. Accordingly the position of the d se i requires at certain times
to be changed but the passenger must be precluded from effecting the change
himself and the driver allowed to do this only in the sight of the said passenger
and by the aid of a key 7° of special shape (Figure 15). In order to obviate fraud

page_text: the position of the disc i must admit of being at any time inspected by the
passenger, for which purpose upon the axis of the disc i, a disc 3 is fixed having
various colours or bearing suitable inscriptions, which, when the key is inserted
turns with the disc i behind the cover-plate of the closed casing E so that through
an aperture G in the cover-plate the rate according to which the fare-indicator is
actuated may always be observed.
In the apparatus represented the fare-indicator proper is put in and out of
action, that is to say, connected with the mechanism actuated by a clockwork or
by a carriage wheel in the well known manner by raising or lowering the slide 1,
as for instance, that described in the Specification of British Letters Patent
No. 9461 dated 18th June 1890 but to effectually prevent this slide and consequently
the hand, being tampered with, the device for imparting suitable movement to the
slide is constructed as follows.
Beside the fare indicator upon a plate m (Figure 13) in the interior of the
casing E is arranged an arm nadapted to turn upon the fulcrum n¹ (Figures 8
and 11) in such a manner that its free end comes within reach of the slide 1, and
that under the action of a spring applied to the said slide it will continually bear
against an eccentric p adapted to turn with the axis p'. The throw of the eccentric
corresponds to the movement of the slide necessary for putting the fare-indicator
in and out of action. Upon the axis is moreover placed a ratchet wheel o
which through the medium of the pawl o permits the eccentric to turn only
in one definite direction. By reason of this arrangement the slide can never
return to the original position before it has completed the movement once com-
menced, it being allowed to return only when the mechanism for actuating the
fare-indicator has first been put either in or out of action so as to be seen from
the outside.
The eccentric p is turned through the medium of the double key (Figure 15)
having an extremity which may be made of various shapes and connected with
the key tube, the extremity being made to fit the journal of the axis p'. Now
to prevent the eccentric p being turned too far so that the slide 1 after its arrival
in one or the other extreine position would commence its return movement too soon
at the extremity of the key a bit ³ is provided and around the journal of the axis pl
a bridge-piece is placed forming the key plate which has suitable apertures
at diametrically opposite points and below this bridge piece upon the plate ma
stop . According to this arrangement a turning movement of the eccentric p (in
the direction of the arrow Figures 8 and 11) can take place only when the bit
is inserted into the aperture in the bridge-piece 4. Exactly after half a revolu-
tion of the eccentric and key the bit strikes against the stop and is then
opposite the aperture 6. In this position a turning movement of the key in one
or the other direction is not possible at all, unless the key is first drawn from the
key hole and inserted again so that the bit enters the aperture. Therefore
the slide can be moved from one to the other terminal position only when the
fare indicator is put in or out of action, and it is therefore impossible to place the
slide during the journey in an intermediate position for causing an incorrect
operation of the fare indicator, as this would at once be recognized by the passenger
or the cab superintendent as the key would stick in its place.
For further increasing the safety, certainty of action and control over the
apparatus upon the axis carrying the eccentric p and ratchet wheel o is secured a
laiger eccentric q which effects the displacement of a bar & placed at a right angle
to the axis p', only in one direction, and which is provided on its face with a pro-
jection serving as a stop. This stop is so arranged that when the eccentric p
and disengaging lever n have assumed the position shown in Figure 11 it would
bear upon the nose t¹ forming part of a second bar t (Figure 13) placed in front of
and parallel with the slide s, which acts in such a manner that the eccentric p, the
lever n and the slide of the fare indicator cannot be moved further, unless the
bart has been slid inwards by a signalling device accessible from the outside to
such an extent that its nose t' is moved out of the path of the projection '

page_text: 9
(Figures 11 and 13). The two bars and t are guided horizontally and connected
with each other by a spring in such a manner that one of them, ri. :-that
denoted by s is forced to the left, the other one to the right hand, and as the
bars bears upon the eccentric the second bar in the position of rest of the
eccentric is just drawn back to the right so far that its nose t¹ must meet with
the projection q¹ in the turning movement of the eccentrics p and q.
=
The displacement of the nose t¹ on the bart from the path of the projection /
take place in a suitable manner by means of a cam w¹ placed in the interior of
the casing E which is arranged upon the rotary axis of a signalling device which
under certain conditions can be turned from the outside. This signalling device
may consist of an arm r carrying a plate or a flag (Figures 1 and 3) with a suitable
inscription which when turned by the driver through the medium of the axis v
and cam causes the bait to be moved to the left until a pawl pivoted to the
stationary guide of the bar t under the action of a spring y' drops into a suitable
notch in the bar in order to hold the same against the action of the spring u in
such a position (Figure 11) that the projection q₁ on the eccentric cannot come
within the reach of the nose t'. It is only then that the eccentric p can be turned
with the right key introduced through the key plate, and that by raising the
slide the fare-indicator can be put out of action (Figure 8). In this turning
movement of the shaft p' effected by the key the eccentric 7, which has a lead of
an angle of 90 degrees relatively to the eccentric p, forces the bars back, causing
it to act by means of the pins, carrying the spring u and extending through the
guide slot in the bar t against the rising edge of a plate laterally connected with
the pawly, thereby disengaging the pawl at the proper moment from the bar t
(acted upon by the spring u which has meanwhile been put under tension). In
this position of the eccentric (Figure 8) the rear end of the bar is in the path
of the cam (Figures 8 and 10) so that the latter, or the signalling device, is
prevented from turning further. The signalling arm placed in the upright
position the flag or plate of which serves to show outside that the vehicle is for
hire or on its home journey or although unoccupied, is otherwise let, can there-
fore be moved to the lower position (Figures 11 to 13) which indicates that the
carriage is occupied, only after the eccentrics p and have been turned through
180 degrees and the fare-indicator has again been properly put in action.
turning movement of the shaft p¹ with the eccentrics and the projection 7 on
the latter strikes once more against the nose t' of the bar t released as described
by the pins, so that it is not possible to turn the eccentric further or disengage
the fare-indicator until by the movement of the arm and flag to the position
corresponding to "unoccupied "the bar is caused by the part w¹ on the cam wo to
advance so as to bring the nose t' out of the path of the projection and stop it
by the pawly. The operation of this safety device for putting the fare-indicator
in and out of action is as follows.
In this
Suppose the vehicle to be unoccupied, the fare-indicator out of action (Figure 8)
and the signalling arm in the corresponding upright position. In this position
the arm is blocked on the one hand by the rear end of the bar s and on the
other hand by the bent piece e' arranged outside and serving as a stop (Figures 8
and 10) the pawl y is disengaged from the bart by the pin s' and the nose ¹ on
the bar is in the path of the projection g' on the eccentric This however is
still in such a position (Figure 8) that the eccentrics p and q can be turned
through 180 degrees before the projection g' meets the nose t'.
Now if on a passenger entering the vehicle the fare-indicator is to be put in
action and the signalling arm to be lowered (Figures 11 and 13) the key (Figure 15)
carried by the driver must be inserted with the bit into the aperture in the
key plate under the observation of the passenger and turned through 180 degrees,
as then only the cam w is released by the bars and the lowering of the signalling
arm x becomes possible. In the lowering of the signalling arm the cam w
causes the bar to advance, whereby the projection g' is released again from the
nose so that the latter after the completion of the journey would enable the

page_text: eccentrics P and
to be turned further, but not the bars which in this turning
movement is forced against the lateral surface of the cam w and thus checks the
movement of the eccentrics. Accordingly the signalling arm a must in any case
first be put upright or in the position in which it indicates that the vehicle is not
used, before the disengagement of the fare-indicator by the continued turning of
the eccentrics becomes possible. In this movement the bars as already stated
is moved in such a manner that it blocks the signalling arm in the position occupied,
whilst the bar t is released, so that the operation of the signalling arm depends
upon the fare-indicator being previously put in action and vice versa and the
disengagement of the latter again on the previous upward movement of the signalling
arm to the position corresponding to "unoccupied effectually obviating the
fraudulent operation of the fare-indicator because this would be possible only in the
sight of the passenger or the superintendent.
Accordingly the more or less imperfect safety devices heretofore provided in
connection with the well-known fare-indicators themselves, and used for a similar
purpose are rendered superfluous.
From the foregoing description it will be seen that a to-and-fro movement of
the bars causes the fare-indicator to be put once in and out of action, and thus
corresponds to a complete journey, therefore the movement of the said bar may be
advantageously transmitted to a counter which serves for controlling the number
of the several journeys made. For this purpose it is expedient to make the pin s'
connected with the bars and carrying the spring u (Figures 13 and 14) in the
form of a pawl or tooth which on the displacement of the said bars engages with
a ratchet wheelj arrested by the pawl 2' and thus causes this wheel to turn with a
step-by-step movement. Upon the axis of this ratchet wheel j, a disc j' may be
placed which, provided with a suitable succession of figures, indicates through an
aperture in the cover plate of the casing E the number of journeys made by the
vebicle.
In cases where it is desired to obtain an indication of the distance passed over by
the vehicle either during a single journey or altogether it is expedient to provide
within the closed casing E a suitable registering device D (Figure 8) which consists
of a counter constructed in the well-known manner and to actuate the same by the
lever 9. The latter then imparts its movement obtained from the wheel of the vehicle
directly to the arm k of the counter which indicates the corresponding distance
through a suitable aperture in the cover plate (Figure 3) of the casing E.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
First. The arrangement of automatic fare-indicators for public vehicles in a
closed casing in such a manner that before the fare-indicator is put in or out of
action a signalling device showing the operation of the latter must be actuated
(before its position can be changed) by means of a key, substantially as and for
the purpose set forth.
Second. In combination with an automatic fare-indicator a device by which the
fare-indicator is put in and out of action through the medium of a lever n and
eccentric and is rendered dependent on the position of a signalling device a
comprising the two bars s and t (having a nose t¹) connected with each other by a
draw spring, having the tendency to move said bars in opposite directions the
eccentric having a projection q' and adapted to be turned only in one direction
by the aid of a key, and the cam w w' fixed upon the axis of the signalling device,
the aforesaid bars and t (according as the fare-indicator is to be put in or out of
action) being placed in the path of the cam during the turning movement of the
eccentric so that the signalling device will be blocked in suitable positions,
substantially as and for the purpose set forth.
Third. In combination with the device, as described, for putting automatic fare-
indicators in and out of action, the mechanisms by which a definite rotary move-

page_text: ment of the eccentric q is ensured comprising the ratchet-wheel o fixed upon the
axis of the latter, and the pawl o' pivoted to the plate m, the projection q¹ on the
eccentric and the nose t¹ on the bar t, the key plate with the apertures
corresponding with the bit of the key and arranged diametrically opposite each
other, and the pin which limits the rotary movement of the key adapted
for the axis p¹ of the eccentric, substantially as and for the purpose set forth.
Fourth. In combination with the safety device, as herein described for putting
automatic fare-indicators in and out of action, a counter which renders the number
of the journeys visible through an aperture in the casing E comprising the
number disc upon the axis of which is fixed the ratchet wheel j held by a pawl j¹
and which in every double movement of the bar s is turned through the distance of
the breadth of one tooth by means of the tooth or pin s' arranged on the said bar
substantially as set forth.
Fifth. In combination with an automatic fare-indicator, the transmission of the
