Improved Apparatus for Indicating and Registering Particulars
connected with the Hire of Hackney Carriages.
I, RENÉ PICARD of the firm of R. Picard & Cie. of 41 Rue de l'Echiquier
Paris in the Republic of France, Engineer 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:-
The object of this invention is an improved apparatus to be provided upon cabs
and the like hackney carriages plying for hire to indicate particulars of the time
distance and charges connected with the hiring of such vehicles so that the fare
may ascertain the amount to be paid in respect of his hiring and the proprietor of
the vehicle may also have the means of ascertaining and checking the amount which
has been earned by the vehicle.
The apparatus for this purpose herein after described has but one lever near the
driver, to be moved to set the apparatus in action so that it does not require any
complicated action or series of actions to set it in appropriate action. The said
hand lever may be placed in any one of the following four positions, indicated by
names corresponding to state of hire of the vehicle. These are 1st "Empty"; the
hand lever should be placed in this notch so long as the vehicle is disengaged.
2nd "Arrest"; a notch to which the hand lever should be moved while the
passenger who has hired the vehicle is settling the question of payment on com-
pletion of his hiring. 3rd "Course"; the notch to which the lever is moved and
where it stays so long as the vehicle is under hire according to distance and
4th "Time"; the notch to which the lever is moved when the vehicle is hired
according to time and not to distance.
The nature of the mechanism is such that the following actions are performed
according to the position of the hand lever in the one or other of the four
notches.
Empty. With the hand lever in this notch ;-An indication of this fact is made
in the lamps of the carriage so that whether at night or by day intending hirers
may at once see if the vehicle is for hire and disengaged. The movement of the
vehicle has no action whatever on the part of the mechanism which indicates and/
registers the amount and total of the fare but has a recording action from which
the distance traversed by the vehicle, the time of such occurence, hence the speed
and duration also the fact of occupation of the vehicle (if such occurs) and the
position of the hand lever, can be seen or inferred.
"Course." Whenever the hand lever is moved into this notch which should
always be done at the moment the vehicle is hired according to distance, the
indication "Empty" disappears from the lamps, the indicator of distance which
shows the fare how far he travels and which had up to this time remained at zero,
now begins to show the actual distance traversed by the vehicle from the point
where the hiring commenced, in say divisions of one hundred yards or if preferred
fractions of a mile, and an indicator of the fare to be paid will be set in action
under control of the "distance" mechanism so that the fare equivalent to the
distance traversed may also be shewn automatically to the passenger. The recording
devices continue to make record as before, but the totals of the distance and of the
amounts paid for fares continue to increase by the amounts of the distance traversed
and fare shown to the respective passenger, which amounts are automatically added
thereto.
Time. When the hand lever is in this notch ;-The indication of "empty" will

page_text: still be absent from the lamps. The passengers indication of the distance traversed
during his hiring will still be shown but this mechanism will have no action on the
indication of the fare. The latter indication is brought under the control and opera-
tion of a clock movement by which therefore the actual fare to be paid is governed
by the duration of time of the hiring instead of by the distance traversed. The
recording devices continue to make record as before, the distance being added to
the total distance record and the fare to the total fare record.
It is presumed that a definite maximum speed of travelling has been fixed for
hiring by time, that is to say when the vehicle is hired by time the distances
traversed should not exceed, say, 8 miles per hour. If therefore for any cause this
speed is exceeded while the vehicle is hired by time the mechanism is so arranged
that the passengers indication of fare is automatically brought under the control of
the distance mechanism so that so long as the excessive speed continues the fare to
be paid is governed by the distance traversed.
Rest (or "Arrest "). When the land lever is placed in this notch-All the
indications remain fixed and unchanging, nevertheless the recording devices will
continue to make a record from which the duration of time during which the lever
is at "rest can be inferred. This position is in order that the indications may
remain visible while the passenger is settling for the hiring with the driver, previous
to the latter returning the lever to the notch "Empty" signifying that the hiring
is ended, the vehicle disengaged and all the passengers indicators returned to their
zero position:
An auxiliary apparatus is added whereby any extra charges there may be
incurred, such as for extra passengers, for luggage, for distance beyond boundaries,
for travelling at night or any others that may be required under the regulations in
'force relating to hackney carriages, may be indicated and added to the totals and
recorded.
It is further advisable to so arrange the apparatus that when hired by distance,
or "Course," the indication of the fare should be removed from the control of the
distance mechanism whenever the vehicle is brought to a standstill or for any reason
only moves at a very slow pace, say one mile an hour and that then the time
mechanism should control the indication of fare, otherwise stoppages would remain
unpaid for and the fare indicated during very slow movement of the vehicle would
be too little looking to the time occupied.
The machine which performs the above indications and records and the con-
struction of which is hereinafter described and illustrated in the annexed drawings
contains in a box facing the passenger certain "Indicators" visible to the passenger
certain "Totalisers" and "Graphic Record" not visible to the passenger but only
visible and accessible to the owner or superintendent who is provided with the key
which opens the case.
وو
The Indicators are as follows;-An indicator of distance traversed, an
indicator of the fare to be paid according to the tariff, an indicator of the extra
charges, if any, an indicator of the position of the hand lever that is to say
whether the vehicle is "Empty," at "Arrest," engaged by "Course," or by
Time," and lastly an indicator of the correct time of day, in other words a
"clock."
The "Totalisers" are as follows;-Totaliser or register of total distance
traversed, totaliser or register of total amount received in fares, totaliser or register
of total amount received in extra charges.
The "Graphic Record" is a revolving disk of paper or equivalent material on
which are pens which trace lines the color and position, length or curve of which
indicate various particulars of hiring as hereinafter more particularly described.

Sheet VIII shows in side elevation a victoria hackney carriage fitted with this
invention.
The distance mechanism by which the record of total distance traversed is shown
on the distance totaliser is as follows; Referring to Sheet III. S is a rod the lower
end of which projects below the case of the indicator and recorder. This rod is
pressed downward by a spring S12 but receives periodical impulsions in an upward
direction from the arm a (Figs. 5 and 6 Sheet VII and Sheet VIII) of a lever
moved through mechanism on the rear axle as hereinafter described so that the
impulsions correspond to definite distances traversed.
When the rod S is lifted the collar S thercon rises with it and suffers the
lever T (Sheet III) to rise under influence of its spring T. The lever T" is
pivoted at T and in rising it meets an adjustable stop To which limits its upward
movement. At the free end of the lever T is a pivoted spring pawl T which
engages with the teeth of the ratchet wheel A' and when the lever T" rises this
pawl moves back over the teeth of the wheel and when the lever T" is again pressed
down by the rod S and spring S" the pawl T revolves the ratchet wheel through.
a distance equivalent to one tooths breadth.
The movement of the ratchet wheel A¹ is carried through a train of wheels B'C'..
to a square shaft Z which passing through to the mechanism in front of the front
frame plate carries there (Sheet II) a ratchet wheel C which revolves by means
of nose on lever P the pin wheel C³ of the unit dial S of the distance
totaliser, and on which shaft Z another ratchet or cam wheel c but having only one
recess at revolves by means of nose Q on lever Q the "tens" dial through
its pin wheel. These two dials R and Sindicate the total distance
traversed.
Indication of the distance traversed by the passenger :-On the rod S (Sheet III)
is an arm S and on a shaft X is an arm S4 having a pin V on which the arm S
presses. The spring S" tends to lift the arm S" and when the rod S is momentarily
raised the arm S is thus lifted. The spring pawl S¹³ rides over the teeth of the
ratchet wheel X fixed on the shaft X and when the rod S again falls under impulse
of the spring S the pawl S¹³ revolves the ratchet wheel X and with it the shaft X¹º.

page_text: On this shaft is a cam Y (Sheet 11) against which the nose of a lever N¹ bears.
The cam Y lifts the lever N' gradually and lets it fall back suddenly at each
revolution of the cam. This movement of the lever N¹ causes the pawi N³ thereon
to strike against one of the pins on a crown wheel O and so revolve this wheel.
On the shaft N3 of this crown wheel O is the "units" disk P₁ carrying the
indications either of yards or of fractions of a mile which are visible to the passenger.
On the shaft N³ is a similar cam Q' governing the bifurcated or compound lever R¹ S¹
which transfers the movement once in each revolution, the lever R' to the crown
wheel T and the lever S₁ to the crown wheel U. The wheel T' is on the same
sleeve as the outer "mile" disk X, the wheel U₁ is however only operated upon
once during each revolution of the dial X owing to the cam U revolving there-
with, this cam keeping the pawl of lever S' out of the path of the pins U₁ until its
recess U100 comes below the pawl. The wheel U₁ is on the same spindle as the
inner "ten mile" disk V, which indicates the distance traversed to the passenger.
This mechanism is placed out of action so long as the hand lever ' of the driver
is in the notch "Empty" by a pin S (Sheet III) on a rotary wheel S" (Sheet II)
which pin arrives under the tail of the pawl S¹³ (Sheet III) and disengages it from
the teeth of the wheel X which is therefore left without movement when the rod S
is lifted. The arm S will then move idly in both directions while the shaft X1° is
prevented from revolving also by a nose X" on the lever V Sheet II which
engages in a heart A which is placed on the shaft X for the purpose of returning
it to zero when all the indicating disks. are likewise returned to zero as herein
after described when the hand lever is put back into the notch "Empty." At all
other times directly a hiring is commenced the movement of the hand lever removes
the pin S as herein after described and also removes the lever V from the
heart A thus allowing the distance traversed during his hiring to be shown to the
passenger.
"

The passengers indication of the state of the vehicle as regards hiring; In the
left hand corner of the face of the case is a small window and behind this window
is a rotary drum U Sheet II which bears on its periphery the words "Empty
"Arrest" "Course" and "Time" or any other words having the meanings formerly
assigned to these words herein. On the end of this drum U is a spur wheel U
taking into a rack V. This rack is connected by a cord V to the lever 'which
is fixed on the shaft on which the hand lever (Sheets I & V) is fixed. The
mechanism in Fig. 1 Sheet 11 is shown in the position occupied when the hand
lever is in the " Empty" notch. When the hand lever is moved from left to
right into any of the other notches the rack V revolves the drum U accordingly
and an indication is given at the aforesaid window equivalent to the position of the
hand lever.
The wheel S is also revolved by the rack V and consequently the pin S
thereon is also brought in and out of action to arrest the operation of the distance
indicator, according also to the position of the hand lever. The spring S" draws
on the wheel S¹ and consequently on the rack V holding the cord V taut.
The "Time" movement ;-A, Sheet III is a spring barrel geared through
train B, C, D with the escapement E. The arbor 10 of the wheel B carries the
minute hand of the clock Sheet I and also the pinion M Sheet II. The pinion M
gears with M and so drives M100 which governs the hour hand in the same manner
as in all clocks. This device therefore constitutes a clock. On the same arbor as the
barrel A is a spur wheel F which may be clutched thereto to revolve therewith or
may be unclutched therefrom. The details of the barrel A and wheel Fare shown
in Figs. 4 to 7 Sheet VI but any method of clutching may be employed. The
clutching or unclutching is operated by the lever G shown broken away in Sheet III
and in full on Sheet III. The lever G is pivoted at G and at Gio it encircles
the moveable part of the clutch. The spring presses on the lever G so as to
always tend to move this lever towards the spring barrel in order to clutch the
wheel F with the barrel and cause it to be revolved thereby.

page_text: The wheel F meshes with the wheel H which is fixed to the side of the wheel I
which drives the pinion I on the same shaft as the star wheel K which operates
the fare indicators and recorders as hereinafter explained.
Indicator of fare;-The teeth of the star wheel K lift the nose of the lever Land
rock this lever so that the pawl L' thercon strikes against the pins on the crown
wheel c and revolves the latter. This crown wheel is on the same shaft as the
disk 10 Sheet II which indicates the units of the fare in suitable fractions. If the
first fraction indicated is to be more than the others in value this is done by simply
writing such value in the first space of the dial co. The star d revolves with the
and periodically lifts the levers e and f which transfer to the dials / through
the pin wheel g, and through pin wheel 10 thus giving an indication of the fare
to be paid on the disks hoc. The cam 90 only allows the pawl of lever f to
operate pin wheel 10 once during each revolution of dial h.
dial

Fare reckoned by distance; On the shaft Z which revolves according to the
distance traversed is a spur wheel D' engaging with a spur wheel E', on the shaft
of wheel E' is a pinion gearing with wheel loose upon the shaft to which the
spur wheels H and I are keyed. On this shaft is also keyed the ratchet wheel G¹
and on the spur wheel F' is a pawl H' which engages with the teeth of the wheel G¹.
The movement of the shaft Z thus revolves the wheel F', the latter revolves the
ratchet wheel G and the wheel I revolves the pinion I¹ of the star wheel K which
brings the indication of fare under the control of the distance mechanism. While
this is in operation the wheel F must be unclutched from the wheel A and kept
unclutched. For this purpose the following mechanism is employed. The upper end
of the lever G is connected to the end of a rocking lever 110 and the latter is
connected by a bridge 1100 with a second rocking lever J, the latter is at its end
connected by a pin Jo with a lever K. On the end of the rod S is an inclined
plane H and at each impulsion of the rod S this plane deflects the lever I10 which
transfers the same action to the lever G and to the lever J, thus to K¹. This action
unclutches the lever G. The spring g (Sheet IIIB) would return the lever system
immediately to its place but it is prevented by the regulator M' which prevents a
quick return of the lever K. This regulator M' consists of a train of wheels ending
in a flying pinion or vane which acts as a governor. The first wheel of the train is a
ratchet wheel M2 and the pivotal point of the lever K¹ is in the axis of this wheel.
On the lever K' is a pawl engaging with the teeth of the ratchet wheel M².
During the movement of the lever Kimparted by the rod S the pawl M³ moves idly
over the teeth of the ratchet wheel M², but when the lever K seeks to return the pawl
engages and the force of the spring has to overcome the retarding governance
of the wheel train and flying pinion of the regulator M' which requires a certain
time. The return of the lever G to its clutching position is therefore slow. Now,.
if the thrusts of the rod S are repeated at sufficiently short intervals to prevent the
lever G ever arriving back at its position of clutching, the wheel F remains.
unclutched. But if the vehicle stops or proceeds at a pace less than one mile an
hour the thrusts on the rod S cease or become so rare that the lever G has time to
fall back and the governance of the fare indicator is taken up by the time move-
ment. This movement gives an accelerated speed to the wheel I through the wheel H
while the ratchet wheel G moves idly under the slower moving or possibly
stationary pawl H on the wheel F.
Fare reckoned by time; When the vehicle is hired by time and the hand lever /¹
is put into the "Time" notch which is the last in the series the vertical rod X
which is moved with rack V arrives high enough to lift the finger Y Sheet II
which projects laterally from the pivoted lever Z (Sheet III"). This lever Z
is thus rocked and arrives in the path of the inclined plane H" on the rod S. This
inclined plane is made upon an articulated part of the rod S and is by the lever Z
shifted backwards so that it no longer moves the lever 110 and consequently no
longer periodically shifts the lever G. The latter therefore remains pressed by the
spring so that the wheel F remains clutched to the barrel A and the fare indicator
is brought under control of the time movement.

page_text: The lever a (Sheet III) carries the indications to the pin wheel b' and thus to
the unit dial d of the totaliser and to the cam wheel c, thence to lever e¹ pin
wheel and "shilling" dial g' in the same manner as before described.
AUTOMATIC ADDITION TO THE REGISTER OF A CERTAIN VALUE FOR THE
TAKING OF THE CARRIAGE AT EACH RETURN OF THE HAND LEVER TO
"EMPTY."
This compensatory addition is required since the first indication to appear at the
fare indicator is greater than the succeeding additions but is only transferred to the
totaliser as equal to one of the later additions. Supposing this excess to be Gd.
this sum must also be added to the totaliser and it is convenient to do this on return
of the hand lever to "Empty." This is operated by the movement of the lever b
(Sheet IV) fixed on the shaft of the hand lever, which when raised meets the
pine of the lever d" which passing in front of the 8 toothed wheel e" moves the
latter two teeth's breadth. This wheel el is on the shaft of the register disk which
indicates the pence in sums of 3d. 6d. 9d. thus twice 3d. (or 6d.) is added at each 4
return of the lever to "Empty."
The graphic register. Certain pens as hereinafter described cause marks to be
made upon a disk divided by 24 radii indicating the hours of the day and night
with subdividing radii of hours from which marks may be seen or inferred first;
the distances traversed by the carriage while empty or engaged, the time and speed 5
of each mile traversed, second; the presence of occupants of the vehicle, the time

page_text: of day and length of time of such occupation, third; the different positions of the
hand lever at Empty" "Arrest" "Course" and "Time" also the time when the
change of position of lever occurs and the duration of period in each position.
The disc is revolved by the clockwork once in 24 hours.
11
The lever a³ (Sheet IV) carries a "Richard" pen at " and receives movement
from the cam wheel gl moved by the distance movement more particularly the
shaft Z (Sheet III). The cam wheel g" thus turns once in a certain distance
causing the pen f" to trace a curve on the paper disk. At the end of each curve
the nose a falls which lifts the pen and causes the latter to commence a new curve
for each certain distance, say ten miles traversed. The position with regard to the
radii and the length and shape of these curves will allow the time and speed of
the vehicle to be ascertained. The rod with counter-spring lifted by the
lever (Sheet VII) which is connected with the lever the latter by cord 1
with the lever under the seat of the carriage, lifts the lever (Sheet IV)
of which the inclined nose engaging under the spring lever causes a pen
thereon to approach the record disc and so trace a line while the vehicle is occupied.
The position and length of these lines will indicate the time and duration of the
occupation of the vehicle. The position of the lever (Sheet IV) determined by
the pressure of the nose m¹ on one of the notches n" of the disc K" the position
of which is equivalent to that of the driver's hand lever determines the position of
the third pen o and holds it in such position until the next change of position
of the hand lever.
CONNECTION WITH THE CARRIAGE WHEEL.
Sheet VII. The side of the axle box of the right rear wheel of the carriage
carries an attachment 1 (Fig. 3) the wheel of which at each turn of the
carriage wheel moves the lever and gives it and its shaft an oscillation against
the spring (Fig. 9) in the box s (Fig. 1) which spring returns it afterwards to
place. On the movement of the lever the jointed pawl on the arm t
(Fig. 1) meeting the dog u of the sector el carries back the sector, which again,
after passage of the pawl returns to its first position under influence of the
spring after having moved the chain y of which the extremity is fixed to the
lever in the drivers seat and thus caused the arm all to strike the end of
the rod S which is thus pushed into the apparatus, say, once for every 60th part
of 220 yards.
The pulleys de guide the chain and the latter is attached by a spring
to the lever to allow for movements of the fore carriage. The tube o which
guards the chain is connected by a ball and socket joint to the box and slides in
the intermediate box (Fig. 4 Sheet VII) so as to allow for movement of the
wheels on their springs.
INDICATION OF "EMPTY
66
AND ENGAGED."
This indication is made in the lamps by a torsional movement given to a spring
lodged in a metallic tube. One of the extremities of this spring moves by a
quarter turn a shutter which gives the required indication (see Sheet VIII) the
other end of the spring is moved by the levers (Sheet V) the prolongation of
which forms the driver's hand lever, the spring being fixed to this lever so that the
movement of the lever twists the spring with it in a manner which will be readily
understood without illustration.

PRELIMINARY DISENGAGEMENT OF ALL THE LEVERS.
After the hiring is completed hand lever is moved towards the notch "Empty
and is placed first in the notch "Arrest." Remaining there, it causes its shaft i to
move the notched disk K" (Sheet IV) the slope of which lifts in passing the
lever & fixed on the same shaft as the lever L (Sheet III) and disengages the latter

page_text: from the cam wheel K and from the pin disk c. It moves also the lever to
(Sheet III) which is connected by link m' to the sliding plate the first
movement of which actuates by a dog n¹ thercon (Sheet II) the lever o' which lifts
and disengages the lever x. It also moves the lever (Sheet II) having the
tappet which moves the lever p¹ and so disengages the levers R¹ S1. At the
Eame time also the movement of the shaft i¹ (from right to left as seen in Sheet III)
frees the springs which draws back the sliding fork t¹ and permits the spring
fork to disengage a clutch which connects the cam wheel.K with its pinion I at
the same time that the pin v¹ on the sliding fork t' passing through the hole ¹
(Sheet II) presses down and so disengages the lever N' from the distance cam
wheel Y and pin disk O¹. The distance indicator and the cash indicators and
totalisers are thus disengaged.
THE RETURN OF THE PASSENGERS INDICATION TO ZERO BY POSITION
OF THE HAND LEVER ON "EMPTY."
Further movement of the hand lever to its position for "Empty" where it is
held by a spring catch and mortise gives a further movement from right to left to
the lever (Sheet II) which causes it to move the sliding frame V₁ and so press
the point double point " and point Z" of the latter against the respective
heart cams A, B and C, D as to carry them and the dials they govern back
to zero.
The lever elevates further the slide
.
(Sheet IIIB) so that the four points of
which E meet the heart cams J J J J (Sheet III) and carry the four dials of
fare indicator and extras indicator back to zero. The slide also lifts the nose F
(Sheet II) against the heart cam J and carries back the tens of shillings disk of
the fare indicator to zero.
COMMENCEMENT OF ACTION OF THE MECHANISM BY THE PLACING OF
THE HAND LEVER AT " COURSE OR "TIME."
"
All the movements of disengagement and return to zero operate or move in the
reverse direction to those above stated, the hearts being first released and afterwards
the levers which then recommence their proper several functions.
ACCESS TO THE TOTALISERS.
>>
The door by which access is obtained to the fare totalisers is held closed by a
lever B of which it forms a part and this lever can only be moved when the hand
lever stands at "Empty." This movement of the band lever into " Empty
allows the stud on the end of the spring tail of the lever y" to fall on the inclined
planey of the disk.K" (Sheet IV) so that this lever y is disengaged from the
notch J in the disk A on the shaft of closing lever B, the opening of the
lever B can then be effected (Sheet V) so that this device can only be opened
when the hand lever is at "Empty."
DISENGAGEMENT OF THE REGISTERING LEVERS BY THE COMMENCEMENT
OF THE OPENING OF THE CLOSING LEVER B" (SHEET V).
During the commencement of the opening of this lever Bu the closing buttons of
the shutters on the windows in the case in front of the fare and extras totalisers are
carried away with. the arms fixed to the lever B" to which they are attached, the
shutters open under the influence of springs so that the numbers on these two
totalisers appear. By continuing the movement of the lever B" the levers which
operate the totalisers are disengaged as follows:
The plate Q(Sheet IV) which is usually kept pressed to the right by the
spring Qrocks on the shaft Q when the nose P on the disk A" meets the

page_text: lug P on the said plate which occurs when the lever B is drawn down far
enough to bring the said pin into contact with the lug. The first stages of this
movement of the plate Qmove the lever ("connected to the plate Q by the
link Q. The lever C is on the same shaft Q as the lever D" (Sheet II) to
which the rods E" and F" are attached. These rods slide in or between guide
pins and their inclined ends lift the levers o and e¹ and so disengage them from the
wheels of the fare and extras totalisers. Previous to this movement the nose [11
will fall into the recess J" (before passing into the face J) and the lever of which
the nose is a part will allow the arm L" to be moved to the left by the
spring K thus throwing back the lever arm M" (Sheet II) which is on the same
shaft Ms as the arm L" causing the window shutter of the distance totaliser in the
front of the case to be released and open as before described with reference to the
fare totalisers. About the same time as the fare totaliser dials are returned to zero
the lever I will be lifted out of the recess Jonto the clevated part J as shown
on Sheet IV, the lever L" is rocked against its spring and the lever M is thrown
inwards (Sheet II) causing the rod N to disengage the lever Q and the rod Q"
to disengage the lever P at the same time that an inclined plane on the rod Nu
bears laterally against and deflects the spring fork N³ which divides the two parts
of a clutch by which the movement of the wheel C' (Sheet III) is transferred to
the ratchet or cam wheels C4 C5 thus disengaging the two dials and operating
ratchets of the distance totaliser.
RETURN OF THE TOTALISERS TO ZERO BY THE COMPLETION OF THE
OPENING OF THE LEVER B".
The
Further movement of the lever B" therefore of the disk A" carries the plate Qu
further to the left that is to say into the position shown on Sheet IV.
noses Q press on the hearts T and return the dials of the fare totaliser and
extras totaliser to zero and the arm C" being drawn further presses further forward
the lever (Sheet II) against the heart k³ and returns the "ten" shilling dial to
zero.
The nose of the lever I" arriving in the highest curve J of the disk A" as shown
in Fig. IV presses the arm L" yet further to the right and causes the lever M"
(Sheet II) to press the noses I against the respective hearts L M N and so
return the distance totaliser dials to zero.
CHANGING OF THE DISKS ON THE GRAPHIC RECORDER.
When the coachman's lever is at empty it is as aforesaid possible to move the
lever B which however will be provided with a lock of any suitable system the key
of which would remain in possession of the superintendant or owner. Only by
unlocking this lock may the lever closing device B" be opened this lever oscillates
the lever n so as to remove it from the stud n' and suffer the door ml of the
box n to be swung open on its pivot m allowing the paper disk to be changed, the
clock to be rewound on uncovery of the opening and the hands on the clock dial
to be adjusted by uncovery of the opening p
SIGNAL
SIGNAL
A bell signal y is actuated by movement of a sliding bar 11 whenever the hand
45 lever is moved in either direction, the levers having noses which vibrate the
lever which moves the bar al aforesaid.

3.) A single hand lever to operate the record and indicating apparatus and also
a lamp indication of "Empty" or Engaged."
4.) The construction for connecting the registering and indicating apparatus with
the carriage wheel, seat and lamps so that the registering and indicating mechanism
in its case may be removed and fitted to any carriage provided with the aforesaid
connections.
5.) The mechanism described for moving the indicating tablets in the lamps.
6.) The mechanism for connecting the wheel with the apparatus for record or
indication substantially as described.
7.) Mechanism by which the speed at which the carriage moves governs the
indication and record of sums payable according to the time or the speed (distance)
scale as herein described.
8.) The mechanism herein described for indication of the sum payable and record
thereof according to "time" or "distance."
9.) Mechanism by which the placing of the handlever at "Arrest
stopping of all indications without stopping the
movements.
"time

causes the
or "distance
"
10.) The mechanism by which the return of the handlever to "Empty" adds a
determined additional amount to the record.
11.) The mechanism for recording graphically the various indications herein
described.
12.) The mechanism consisting of a cam disk with concentric notches which
carries a pen to an elevation corresponding to the relative position of the hand
lever.
13.) A cam wheel for the "distance" movement, which causes the return of the
pen to zero at the same time that the distance totaliser is returned to zero.
14.) The mechanism for retaining the paper record disk and obtaining access
thereto as described.
15.) The mechanism herein described by which the distance indicator is moved
by the "distance" operating movement, but may be returned to zero independently
of said operating movement.
16.) The mechanism by which the distance operative movement and the time
operative movement govern the same apparatus whereby the time movement may
move faster than the distance movement or the distance may cause the record when
it exceeds the definite maximum provided for by the time movement as herein
described.
17.) The mechanism by which the apparatus can be opened only while the hand
lever is at "Empty" for the purpose set forth.
