Improvements in and relating to Registering and Indicating
Machines or Apparatus for Hackney Carriages.
I, OVIDE DOMON, of Morteau, Department Doubs, in the Republic of France,
Watchmaker, 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 to provide a registering and indicating machine
to be attached to vehicles plying for hire or hired vehicles and more especially
to those in respect of which the driver is under the necessity of accounting to
the owner or principal for the cash takings, the said machine being adapted to
show the occupant of the vehicle the distance traversed or time during which
the vehicle has been occupied by or engaged by such person and the fare or
tariff for such distance or period and extra charge if any such as for night hire,
luggage, extra passenger if extra charges are made for these or any of them and
being adapted also to show the total cash takings which the driver has received
or should have received and having a clock giving the time of day.
A further object of the invention is to provide means for indicating whether the
vehicle is engaged or not.
In the accompanying drawings Sheet I is a front elevation of the exterior of the
machine.
The machine is preferably arranged on or near the seat of the driver and within
his reach. The side nearest the driver carries the handles etc. for setting the
machine in operation and its interior surface facing the occupant of the vehicle
indicates the mileage and time and the fare, also the correct time, the sum of the
cash in hand as well as of the number of miles covered since the exit of the vehicle
from the stables.
The movement of the handle operates the appearance or the disappearance of
small transparent shutters having the indication engaged" on the upper part of
the outer glasses of the two carriage lamps. These shutters are easily scen from
near or afar and indicate in the day time as well as at night whether the vehicle is
for hire or not.
I is a large principal dial for time and distance having two visible hands working
separately to indicate the miles covered during normal progress or the indication of
time giving for the time, the equivalent in miles at the rate of say 6 miles per hour
and this also when by wish of the passenger the driver stops or proceeds at a slower
speed than the normal one.
In this case the coachman pushes the bolt on the hour or time indication; this
motion stops the mileage system and sets the time work in motion.
At the side of this time and mileage dial is the tariff window 2 which shows
automatically to the traveller in one number and at any moment during the drive
the amount which he has to pay to the coachman.
The lower of these windows indicates the payment to be made for extra charges.
3 is a special dial indicating the correct time: it serves also to show the time when
the additional night fare begins.
On the right hand side above, are the two windows 4 for the sum of the cash in
hand received by the coachman that is the addition of the successive amounts shown
by the indicating windows, the one of these controlling windows indicates the cash
in hand according to the tariff the other one the cash in hand according to the
extra tariff.
Above to the left of the apparatus is a special dial 5 indicating the amount of
miles covered by the vehicle since it left the stables.

page_text: On the right hand side of the apparatus is a lever door, which upon opening
shows a recess for winding up the mechanism and another for putting back the
time and the alteration of the dials of the speed control and for operating the
putting back to starting point of the controlling apparatus.
This operation is done in the stables by the controlling clerk in presence of the
coachman; they will both see immediately and without any calculation the
amounts which are to be paid over by the coachman and the total of miles covered.
The special arrangement of the mechanism prevents undue or untimely inter-
ference which might interfere with the indications of the apparatus or spoil it.
The time indicator of the apparatus is operated by a spring and may be made to
work for about 40 hours.
The distance indicator is worked by electricity by a battery of small size but
sufficiently powerful placed underneath the coachman's seat. Its current operates
the apparatus at cach revolution of one of the wheels by means of a contact box
fastened underneath the axle.
The battery supplies besides instantly and at will current for a light for reading
the apparatus during darkness.
The electric contact apparatus is arranged in such a manner that whatever may
be the position-of-the-motive-wheel,-a-continuous.contact is impossible.
Under these conditions, the maximum duration of the contacts, that is of the
discharge of the battery, does not exceed 12 to 15 minutes for a distance of
100 miles which ensures the battery working for a duration of at least 7 to
8 months.
The construction and disposition of the electric apparatus are such that the latter
is perfectly proof against any sudden shocks, the largest oscillations or jolts, the
effects of rain, dirt or frost; it resists hurtfully intended acts of the coachman or
other person-and-it-is protected-from-accidental.or.intentional wrong contacts.
The apparatus is lighted up by a small movable electric lamp which will light
up automatically when it is placed in front of the apparatus and the light of which
-will-last-every-time-long enough to enable the indications to be read.
Pneumatic-action-operates automatically the indication of hire in the lamps of
the carriage.
In Sheet II, is the electro magnet having two bobbins operated by the passage
of the current of the battery, cach revolution of the wheel operating the contact
switch.
At-each contact, the electro magnet draws the armature 3 which moves the
motor wheel 7 of the mileage mechanism by one tooth. 2 is the base of the electro-
magnet. The armature 3 pivots at 31 and operates by its motion the toothed
wheel 7 by means of the pawl 4 and its spring 5. It has at 3 a notch which
receives the pressure of the spring 6 which throws back the armature 3 after the
passage of the current in the electro magnets.
A wheel train 7, 8, 9 carries the motion of the wheel 7 to the mileage dial 5
(Sheet I).
The relative sizes and number of teeth are calculated in the known manner.
The intermediate wheel 11 transmits the motion of the mileage mechanism to the
wheel 13 and from there to the mileage hand of the dial 1 (Sheet I). This
wheel 13 is located on an upper plane, that is it passes above the motor barrel 16
_and_the_clectro_magnet 1, it has also at its inner part a drawback 14 for its return
to zero.
The wheel 13 transmits its movement by the pinion 25 to the transmitting
levers 27 and 32. The wheel 12 is on a lower plane namely underneath the motor
barrel 16 and the electro magnet 1; it carries firmly on its shaft immediately
underneath the drawback 14 a drawback 14' for its replacement to zero.
The two
large time and distance wheels 12 and 13 each carrying conjointly with it its
drawback 14 and 14' are taken back simultaneously to zero by the pressure of the
return lever (14 and 15 Sheet III).
In order that the return to zero may be better understood the wheels operate

page_text: loosely the mileage wheel on its shaft and the time wheel on its cylinder
adjusted on the shaft and shaft and cylinder are carried along by the motion caused
by the forked springs fastened upon these wheels and grasping the shaft and the
cylinder with sufficient power to prevent the needles becoming displaced by the
shaking of the carriage.
This arrangement is not shown on the drawing for the superpositions of
the spring arrangement would have prevented clear illustration of the other
mechanism.
16 is the motor barrel within which is the motor spring having a traction power
of 14 lbs. or thereabouts upon the teeth; a train of wheels 18, 19 20 and 21
transmits the motion to the escape wheel 22. This barrel motor makes one revolu-
tion in 8 hours.
18 is a large wheel of 75 teeth on a pinion of 12 teeth which communicates to it
the motion of the barrel 16 which also it transmits to the wheel train by the pinion
of the wheel 19. This wheel makes one revolution per hour and its pinion being
perforated moves by friction a pin carrying outside of the dial the minute hand.
24 is a loose pinion with 15 teeth gearing with the large time wheel 12 carrying
at its inner part a clutch of less diameter provided with cuts intended to transmit
its motion to the drum 26 when the latter is raised by the tension spring 45.
25 is the mileage loose pinion of the same dimensions working as with the
previous one 24 but gearing with the mileage wheel 13 from which it transmits
the motion to the drum 26 when the latter rests against it by the pressure
exercised by the lever 13 (Sheet III) upon the tenon 45 of the tension spring 45.
The drum 26 has on its smallest and lower diameter an orifice in which gears the
horns of the tension spring 45 which raises it to gear it for time and which lowers it
to gear it for distance for it has at each of its two sides a clutch which according to
the action exercised upon the tension spring 45 causes it to gear with the one or
the other of the two loose pinions 24 and 25.
This drum or cylinder has on its large diameter at the half of the lower height
12 ratchet grooves equivalent to the half quarters of an hour for the drum makes
8 revolutions in 12 hours by the time impulse that is for one revolution of the time
wheel 12. This drum also carries on its larger diameter 12 grooves or teeth formed
of an inclined plane on one side and of a radial plane on the other one.
These inclined planes carry a subdivision of 10 notches within any one of which
the nose of the transmitting lever 27 will stop and against which the drum slides
without recoiling which would cause a loss of time at the time of change of the
vertical position to proceed from the time motion to the distance motion and
vice versa.
The transmitting lever 27 falls successively into the grooves on its passage over
the 12 grooves. The nose of the large transmitting lever 27 is raised gradually
by the inclined shape of the grooves of the distributing drum 26 then falls quickly
into the following groove.
This slow disengaging motion is transmitted, amplified in the ratio of 3 to 1
to the other end of the lever which disengages itself from the teeth of the star 28
without moving it to any extent in view of the flexibility of the small spring
fastened to the end of this lever.
Falling back into a groove, the lever 27 under the impulse of the spring 30
takes up quickly its first position, pushing the ray of the star 28 which it meets
to the extent of of the space between the teeth the other quarter of the
motion is determined by the cross spring 281 which keeps the star 28 stationary
until a further impulse. The star 28 has rays equivalent to the pence of the
tariff carrying the indicating disc for payment according to the tariff. It receives
tooth by tooth the impulse of the transmitting lever 27 which it transmits to
the indicator disc of the shillings of the day (29 Sheet III) at each change of
unity the cross spring 28¹ keeps it stationary after having accellerated the end
of the impulse motion, which it has received from the transmitting lever 27.
29 is the secondary transmitting lever with the transmitting lever 27 against

page_text: which it is constantly supported by the spring 30 this secondary lever transmits to
the star of the control 31 but in the contrary sense the same motions of the lever 27
agitating upon the star 28.
The star 31 carries the controlling pence disc 32 (Sheet III) and transmits at
each change of unity to the controlling shilling disc 33 (Sheet III) the motion
which it receives from the lever 29.
The shaft of this star carries in the lower plane (Sheet IV, 11 and 14) a ratchet
wheel-for-the-compensation _for_the addition of control, and a drawback heart for
replacing to zero.
31 is the spring holding the star 31.
32 is the transmitting lever for the supplementary fares operated by the small
handle 3 on Sheet V.
The star 33 carrying the indicator disc of the pence to be paid shows the supple-
mentary charges (30 Sheet III) like the star 28; at each change of unity it
transmits its motion to the shilling disc (31 Sheet III).
33 is the spring holding the star 33.
34 is the secondary transmitting spring transmitting to star 36 (the controlling star
of the pence of the supplementary charges) the motion which it receives from the
lever 32.
35-is-the-spring-operating-the-lovers.32_and_34.
The star 36 working simultaneously with star 33 carries the controlling disc of
the pence of the supplementary charges and on a lower plane on its axis
(Sheet IV 16) a drawback heart for replacing to zero.
361 is the spring holding the star 36.
The coupling spring 45 normally holds the drum 26 geared with the loose
hour pinion 24. Under the pressure exercised lever 13" (Sheet III) upon the
part 45, the spring disengages the drum 26 of the hour pinion 24 without how-
ever engaging-it-with the-distance-pinion 25 which does not take place until
the nose 13 completely engaged upon the tenon 451 by the position of the
bolt 9 (Sheet III) into the position of the working for mileage, causes it to.
-gear-with-the-pinion 25...
46 is the shaft transmitting through the devices on Sheet II-the-motion-for-the-
placing on the zero point from the mechanism of the inferior plane (Sheet IV) to
the mechanism underneath the dial 38 38' 38" (Sheet III).
47 is the pivoting shaft of the handle traversing entirely the apparatus on its
3 planes II, III and IV.
48 and-481 are passages for the disengaging pins of the transmitting levers 27
and 29 or 32 and 34 according to the change from the working of the day tariff
to that of the night.or supplementary tariff.
49 is the handle operated by the coachman the position of which determines the
putting into operation or the stopping of the mechanism as well as the indication of
hire in the lamps.
50 the disc shaft 35 (Sheet III) carrying on the other plane (Sheet IV) a draw-
back heart for replacing to zero.
51 the disc shaft 33 (Sheet III) carrying on the other plane (Sheet IV) a
drawback heart for replacing to zero.
On Sheet II the handle 1 is shown in the drawing in position of engagement
with mileage working pivoted at 1'. 11 is the position of the handle when dis-
engaged. 2 is the lever arm fastened to the shaft of the handle and in one piece
with the latter, by its engaging notch the pin 4 operates the-slide-of the change
of working 4 and by its pin 8 acting alternately against the noses 7" and it
determines the motion of the slide 7 for the putting into motion the working of the
mileage or hour mechanism. 21 is a lever arm of arched shape fastened by two
screws upon the lever 2 and at the end of which the nose 211 encounters the nose
of the lever 14 the motion of which determines the replacing on zero of the two
hour and distance hands. 3 are three steel blocks superposed on inclined planes
atsuccessively which determine in succession the motion of the lever 18

page_text: agitating upon the vertical slides 20 21 and 22 respectively for the placing on zero
of indicating dials. 5 5 are guides for the slides 4 and 7. The horizontal lower
slide 7 carries the pin 9' and moves the lever 9 by one half of its run, the toothed
arc 9 gearing with the toothed wheel 12 carries back the nose of the lever 13"
notched at its lower part which whilst allowing the head of the pin to rise a certain
distance disengages the impulse of the mileage hand.
The lever 9 for changing the working rendered stationary by the slide 7 when
the handle is disengaged but when the handle is engaged the lever for the change
of the working being pushed to the right determines the putting into motion of the
whole mileage system whilst when pushed to the left it puts into motion the time
measuring, this change of operation is effected by the position of the lever 11 on
the guide 45 (Sheet II) which controls the horizontal motion of the drum
(26 Sheet II) leaving it free for the time indication or pressed downwards for the
mileage indication or kept in the intermediate position when the apparatus is free
or at rest.
The prolongation 15 of the lever 14 is folded down square so that it passes
underneath the large hour wheel (12 Sheet 11) for the roller 15' to move hori-
zontally in the same plane as the drawback hearts (14 and 14' Sheet II) against
which it operates. 16 is a passage in the plate for the nose of the lever 15. The
spring 17 tends to push back the lever 14 against the stop screw 14".
The three levers 18 of the shape shown being superposed and pivoted at 1811
transmit the motion occasioned by the successive passages of the slopes 31 311
and 3 against the noses 18' successively and respectively to the vertical slides 20
21 and 22.
Three superposed springs 19 tend to push the levers 18 back to the zero resting
point. The vertical slide 20 is operated by the fork of the lower lever 18 and
raises in its upward motion by the pins 20 and 20" the four transmitting levers
(27, 29, 32 and 34 Sheet II).
The slide 21 operated by the fork of the intermediate lever 18 carrying at 21
the rollers 21 and 211 which by their upward motion place at zero, the discs 28
and 30 by the action exercised against the hearts 26 and 27.
The third vertical slide 22 operated by the upper lever 18 which gives it an
upward motion, raises the rollers 22 and 22111 against the drawback hearts 24
and 25 to operate the replacing on zero of the discs 29 and 31.
23 and 23 are guides for the slides 20, 21 and 22. 24, 25, 26 and 27 are the
drawback hearts of the discs 29, 31, 30, and 28 respectively. 28 is the indication
disc of the pence, according to the tariff, operating the disc 29 by the thrust of the
teeth upon (indicating the carrying over) encountering the teeth of the star
which is placed underneath the disc 29. 29 is the disc showing the shillings to
pay according to the tariff. 30 is the disc of the pence to pay for extra charges
operating the disc of the shillings 31 also for the extra supplementary charges.
32 is the disc of the pence of the control according to the tariff in one with the
star (31 Sheet II) by which it communicates the motion to the disc 33 at each
change of unity.
The disc 33 of the shillings operated by the disc 32, the shaft of which (51
Sheet II) carries on a lower plane (in Sheet IV) a drawback heart, this disc controls
in shillings the cash in hand according to the tariff.
34 is the disc of the pence of the sum of the extra charges fastened to the star
(36 Sheet II) by which it communicates motion to the disc 35 at each change
of unity. 35 is the disc of the shillings of the sum of cash in hand on account of
extra charges, fastened to the shaft (50 Sheet II). It carries at its interior side
(Sheet IV) a drawback heart.
The parts 30, 32 and 34 operate respectively the discs 31, 33 and 35 in the same
manner as the part 28 operates 29.
36 is the wheel train operating the "10" hand of the mileage disc 3 (Sheet I).
37 and 37' are the drawback hearts for the mileage indicating hands the placing
to zero is operated by the action of the lever 38 under the impulse which the latter

page_text: receives in (Sheet IV) by the disengaging motion of the winding up and controlling
door. 38 is a forked coupling spring maintaining by its pressure the impulse of
the mileage dial train. The impulse of the sleeve operating the dial train 36 is
performed by the pressure of a toothed plate underneath this sleeve and pressed by
the forked coupling spring 38" against an impulse plate fastened firmly on the
mileage shaft for replacing upon zero; the lever arm 38 raises the forked coupler to
disengage the impulse discs before the double pulley 38" comes into contact with
the hearts 37 and 371 which it moves to zero position. The sleeve should run loose
on the shaft. Each of the two wheels of this dial train is secured-by-friction by
two small friction springs to allow of their forward or backward motion whatever
their position may be. 39 is the dial train of the minute work operating the hour
and minute hands of the dial giving the correct time of the place.
In Sheet IV 1 shows the handle by which the coachman operates the setting in
and out of action of the various parts.
This handle or lever is shown on this sheet so that the mechanism may be better
understood although it is usually arranged outside the apparatus on the side
nearest the coachman. 2 is the guiding segment on which the handle slides; it
carries two very accentuated notches into which a strong spring on the handle
throws the latter to when at the one or other end of its course. 3 is a lever
fastened-to-the-shaft 1 of the handle 1; it carries an inclined plane at 31, which
when the handle is in position of disengagement encounters at the end-of-its run-
the roller 4 of the fork lever 4 which pushes the compensation slide 6 to the left
on the guides 10, 10¹. The lever 3 carries a sector at 45 on an inclined plane
which operates the safety apparatus of the door for winding up. 5 is a spring
controlling the lever 4. On the movement of the slide 6 to the left the flexible
straight blade spring 6 encounters the teeth of the ratchet 11 and causes it to
advance for a distance equivalent to the breadth of two teeth, and with it the
-star (31-Sheet II) and the disc (32 Sheet III) completing thus the compensation by
the addition to the sum of the fares of an amount equal to the fare-for-the-first
occupation of the carriage.
25.and 26 are guides for the slide 27 the latter being-operated by the lever-17
and commanding at 28¹ the indication of the extra charges-by-means-of-the-arm_28_
fastened to the slide 27 and carrying a dog at 28 traversing the passage
(48 Sheet II) and gearing underneath the transmitting lever (32 Sheet II). 34 is
the lever for the door provided with a lock (at the outside Sheet V) and connected
to the disc 35 as seen in Sheet V. The disc 35 operated by the lever door 34 has
two projections which determine successively the motion of the zero placing
levers 36, 39 and 41 and it carries an arresting block against which abuts the
lever 44 if the latter has not been disengaged by the position of the handle on free.
This arrangement has for its object to prevent the opening of the-door lever and
motion of the putting back levers without the hearts, discs and stars having been
previously disengaged. The lever 36 transmits its movement at 36' to the lever 37
and thus places upon zero of the mileage indicators (38 Sheet 111). 38 is a
spring controlling the lever 37. 39 is a double acting lever acting against the
hearts 14 and 16 to replace them to zero. 40 is a spring controlling the lever 39.
41 is a double acting lever acting upon the hearts 13 and 15 for replacing them to
zero and 42 is a spring controlling the lever 41.
47 is the clockwork (24 hours) working the recording of the information on
_ paper. 48 is the ratchet for winding up the same. 49 the stopping pawl of the
ratchet 38 and 50 the spring thereof 51 is the-bridge for holding the minute
wheel and preventing the barrel from becoming displaced. 52 is the plate fastened
to the barrel and on which the disc 53 may be adjusted by hand. 53 is a large disc
which presses against the disc 52 a paper disc upon which is automatically
impressed the indications of the hiring and extra charges. This large disc is
worked to rotate one revolution in 24 hours in firm connection with the base disc 52
by a pin 53 traversing the two. 56 is a stylus which when free, that is when by
the motion of the handle 1 upon “engaged” the fork of the lever 4 is thrown

page_text: back will by its natural tension press with its point against the control dial. On
the other hand with the position of the handle 1 on "free" the fork pushed to the
left passing a projection on the spring of the stylus lowers its point and leaves the
dial to turn without indication. 57 is a powerful spring raising the slide 27 and with
it the small lever of the extra charges (3 Sheet 5). 58 is a spring lever with
stylus of the same shape and working similarly to 56 but marking in dots and not
in lines on a special zone of the dial to make each extra charge to be paid by the
hirer. 59 is a lever connected with the slide 27 so that at each lowering of said
slide, the said lever raises the end of the spring stylus 58 and thus determines the
impulsion of a coloured point on the central dial indicating thus the number of
fares collected and the time at which they were collected.
Sheet V is a view of the back of the case. 1 is the large lever (in the position of
engaged). The putting into this position determines the starting of the apparatus,
the indication of engaged in the lamps, as well as the augmentation on the control
discs in compensation of the extra cost of the first mile of hire (where a less
charge is made for each succeeding mile than for the first one).
By moving the large handle 1 to the position of "free" 11 the hour and
mileage mechanism is stopped, the indicating dials for the amounts to be paid to
the coachman are put back for the next hiring of the carriage. The control dials
remain stationary showing the amount of cash in hand after the last payment for
hire and ready for the registration of the subsequent additions. 2 is the bolt for
the change of working in position for the mileage measure. 2 shows the position
of the bolt for the "time" indication. 3 is a small handle for the extra charges
the lowering of which by the coachman determines the indication of a fare to be
paid the apparition of which is modified to the occupant by the sound of a bell. 4 is
the piece connecting the door with the toothed segment 41 which is in firm
connection with the disc 35 (Sheet IV) and 4" is the lock which cannot be tampered
with and of which the owner or his authorized collector alone has the key.
The opening of the door communicates motion to segment 5'; the lever 5 will
swing and expose the openings 6 and 7 allowing the putting back to the hour and
the change of the paper dial by the opening 8 as well as the winding up. The
part when closed engages by means of its semicircular notch into the lower part of
the button 8 and thus keeps it stationary and locked against the plate.
8 is a closing disc which may be moved to the right on its pivot 8" when the
gear lever 5 is lowered to allow the setting of the clock and the changing of the
paper disc.
Sheet VI shows horizontal sections on lines A. B, C D respectively of the
views on Sheets II III IV and V.
Sheet VII shows a perspective view of the registering and indicating machine
and its application to indicating "engaged" in the lamps.
9 is a lever in connection with the coachman's handle having at its lower end a
rod which operates an air pump 10.
The air pump operates, by a tube 11, bellows made of rubber or other material
which is enclosed in a cylinder 12.
These bellows move the shutter "engaged" by means of a small horizontal rod
and a small vertical one penetrating into the lamp. When the handle is free the
pressure is cancelled and by means of a spiral spring in the interior of the lamp
the shutter "engaged" is folded out of sight.
Sheet VIII shows a brougham fitted with the herein described apparatus. The
contact box 1 of cast iron completely protected against effect of shock, mud,
frost etc. is fastened to the shaft between the springs and the nave of the right
hand hind wheel. The flexible electrical conductors 2 may be constructed as
follows:
Extra flexible conductors of 30 strands of 100m insulated in a sheet of pure
rubber (Para) non softening, surrounded by a thin "Chaterton" ribbon with a
layer of jute and a twisted covering layer of galvanized steel wire of about
guage and very pliable in order not to give way by pressure or Hexure. The

page_text: poles of the cables are provided with rings of copper enamelled outside so that
short circuits may not be established by evil intention, mud, water, or ice. The
rings are bolted to the interior of the contact box (Sheet X).
3 is the battery operating the electro magnets of the apparatus by means of the
contact box and giving the light for reading the apparatus during the night by a
small reflecting lamp. 4 is the registering and indicating machine placed to the
right behind-the-seat of the coachman, sufficiently high for the opening of the
winding up to be above the seat, the face being well in view of the passenger. 5 are
the lamps with movable shutters the latter having either a horizontal pivoting
motion or a lowering or raising one.
These shutters are operated automatically by pneumatic pressure as aforesaid.
Sheet IX shows the contact box in two views. is the contact box fastened by
the plate 5 and the bolts 6 underneath the axle between the springs and the nave
of the right hand wheel behind.
The lever 3 fastened to the square end of the shaft 2 of the contact switch of the
box is pushed by the finger 8 at each revolution of the wheel which gives it a
lateral deflection of about 30 degrees or of a revolution. The period of deflection
will exist during a length of of the turn of the wheel. The first position
of the lever is restored after the said deflection by the action of the spring
(5 Sheet X).
4 is the-iron rim of the nave of the wheel to which is screwed the piece 7 which
carries the finger 8.
Sheet X shows the interior of the contact box in two views. A. is the cast iron
box containing the mechanism of the contacts.
I is a drum, having at 4 a square which carries the finger 3 (Sheet X).
The feather 2 which traverses the drum 1 slides backwards when it encounters
the inclined plane 10-behind-which_it.engages; this feather is always under the
action of the spring 3 which pushes it forward.
5-is-a-strong spiral spring carrying the drum 1 back into place when the lever 8
has left the finger-3-(Sheet X).
The slide 6 is pushed to the right under the action of-the-feather-2-against the
part 10; its motion is regulated in the slide guides 7 and 8 and its movement of
which is cushioned by the bellows 11.
The spring 9 takes back the slide 6 when the feather 2 has left the detent 10.
12 is a spring lever abutting against the block 13 keeping open the bellows 11
during the recoil of the-slide-6. 14 is an ebonite plate carrying the plate 15 and
the contact block 16, and 18 are terminal screws carrying the wire from the battery
and indicating machine. 20 is a flexible contact spring encountering the insulating
surface of the contact block 16 when the slide 6 moves to the right.and establishing
the contact by the conductor surface of the block 16 when the slide 6 released by
the feather 2 returns backwards under. the impulse of the opposition spring 9 at
a speed moderated by the bellows 11 allowing an interval of sufficient duration for

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-registering and indicating machine constructed to show the duration in time
or distance of the hire of a vehicle with an indication at-all times of the fare due
with extra charges if any.
2. A registering and indicating machine constructed to show in one sum the total
amount of cash received by the coachman of the vehicle substantially as herein
-described.
"
3. In a registering and indicating machine the mechanism for setting the
indication for the "time or the "distance" by means of a hand lever and the
indication of the fare or fares to be paid in respect thereof substantially as
herein described

page_text: 4. In a registering and indicating machine a hand lever adapted to set indicating
and registering mechanism in action and by its movement to this end automatically
add or show an initial charge to the fare to be paid by the hirer for the purpose set
forth.
5. In a registering and indicating apparatus the contact box constructed so that
the action for electrical contact is set in position for action and is released, but is
otherwise independent of the parts thus operating it, whereby fixity of contact in
any position of the operating parts is avoided and a contact of uniform duration
obtained.
6. In a registering and indicating machine the combination with the starting
hand lever of shutters in the lamps of a vehicle and pneumatic connections sub-
stantially as described whereby the fact of engagement of the vehicle is indicated
by an appropriate word or device in or by the lamps.
