Improvements in Fare Registering Apparatus for Vehicles.
1, HENRY HARINGTON LEIGH, Assoc. M. Inst. C.E., Fel. Ch. Inst. P.A.,
F.I. Inst., practising as Phillips and Leigh, at No. 22 Southampton Buildings,
Chancery Lane, in the Administrative County of London, Engineer and Patent
Agent, do hereby declare the nature of this.invention to be as follows:-
This invention relates to improvements in fare registering apparatus for vehicles
and consists of a compensating or adjusting device to be interposed between the
measuring wheel of the vehicle and the fare registering apparatus.
The different diameters of the vehicle wheels necessitate each apparatus which
registers the fare or measures the distance covered by one of the vehicle wheels, to
be adjusted according to the size of such wheels in order to make the apparatus
fitting for such vehicle. For this reason up to the present time, the manufacture
of such apparatus in quantities has not been possible. The purpose of the present
invention is therefore to allow such manufacture.
In carrying this invention into practice I fit to the vehicle, and preferably on the
driver's seat, a rotating body (crank, wheel or the like) connected with the
measuring wheel of the vehicle by any suitable pneumatic, hydraulic, electric or
mechanical device. The speed of the said body corresponds with that of the
measuring wheel of the vehicle. The rotating body is brought into connection
with the fare registering apparatus by means of a coupling device which acts, for
instance, in such a way that placing the fare registering apparatus upon the said
rotating body, effects the coupling there and then, the said body being thereby
enabled to transmit motion to the apparatus.
The measuring wheel is fitted with some device enabling it when in motion, to
actuate such a mechanism as a pneumatic pump which reciprocates a column of air
by means of a suitable piping within a channel of the above mentioned adjusting
device, thereby moving to and fro. a suitable membrane arranged at the other end
of the said channel. Attached to the membrane is the end of one arm of a bell
crank or other suitably bent lever, the other arm of which carries a ratchet pawl
engaging with a ratchet wheel provided with a suitable rib or notch. The ratchet
wheel is rotated on its pivot, step by step, by the pneumatic impulses produced by
the measuring wheel of the vehicle and transmitted through the medium of the
said membrane, the bell crank lever and the ratchet pawl. A suitable check pawl
prevents the ratchet wheel from any return movement.
The speed of rotation of the ratchet wheel must correspond to the circumference
of the measuring wheel as already stated above. In the present construction, this
proper adjusting may be easily obtained by employing ratchet wheels of a
corresponding number of teeth or by adjusting the length of the arms of the bell
crank.
The rotary motion of the ratchet wheel may then be transmitted to the driving
orank of the registering apparatus by means of the above described rib or notch,
engaging with the said driving crank.
By means of the above described adjusting device interposed between the
measuring wheel and the fare registering apparatus and adapted to compensate the
difficulties produced by different diameters of the vehicle wheels, all fare registering
apparatus, can be made according to one-standard model.

F.I. Inst., practising as Phillips and Leigh, at No. 22 Southampton Buildings,
Chancery Lane in the Administrative County of London, Engineer and Patent
Agent, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in fare registering apparatus for vehicles
and consists of a compensating or adjusting device to be interposed between the
measuring wheel of the vehicles and the fare registering apparatus.
The different diameters of the vehicles wheels requires that each apparatus
which registers the fare or measures the distance covered by one of the vehicle
wheels, shall be adjusted according to the size of such vehicle. For this reason
up to the present time, the manufacture of such apparatus in quantities has not
been possible. The purpose of the present invention is therefore to allow of such
manufacture.
In carrying this invention into practice, Ifit to the vehicle, and preferably on
the driver's seat, a rotating body (crank, wheel, or the like) connected with the
measuring wheel of the vehicle, by any suitable pneumatic, hydraulic, electric or
mechanical device. The speed of the said body corresponds with that of the
measuring wheel of the vehicle; The rotating body is brought into connection
with the fare registering apparatus by means of a coupling device which acts, for
instance, in such a way that placing the fare registering apparatus upon the said
rotating body, effects the coupling there and then, the said body being. thereby
enabled to transmit motion to the apparatus.
:
In order that my invention may be more fully understood by one skilled in the
art to which it appertains, I will now proceed to describe it in detail; and for that
purpose shall refer to the accompanying sheet of drawings whereon similar letters
of reference indicate corresponding parts throughout the several views.
Figure 1 is a diagram showing a vehicle furnished or provided with my improved
apparatus; Figure 2 is a sectional elevation, and Figure 3 a plan of the apparatus
drawn to a larger scale.
The measuring wheel & is fitted with some idevice. as adapted to. enable it,
when in motion, to actuate such a mechanism as an air pump which reciprocates
a column of air by means of a suitable pipe g within a channel of the above
imentioned adjusting device, thereby moving to and fro a suitable membrane e
arranged at the other end of the said channel. Attached to the membrane is the
end of one arm of a bell crank or other suitable beut lever c, d, the other arm d of
which carries a ratchet pawl 6 engaging with a ratchet wheel a provided with a
suitable rib or notch i. The ratchet wheel is rotated on its pivot al, step by step,
by the pneumatic impulses produced by the measuring wheel of the vehicle and
transmitted through the medium of the said membrane, the bell crank lever and
the ratchet pawl. A suitable check pawlm prevents any return movement in the
ratchet wheel;
The speed of rotation of the ratchet wheel must correspond to the circumference
of the measuring wheel, as already stated above. In the present construction, this
.necessary adjustment may be easily obtained by employing ratchet wheels of a
corresponding number of teeth. or by adjusting the length of the arms of the bell
crank.
The rotary motion of the ratchet wheel may then be transmitted to the driving
crank of the registering apparatus A by means of the above described rib or
"
notch engaging with the said driving csonk 1

page_text: By means of the above described adjusting device interposed between the
measuring wheel and the fare registering apparatus and adapted to compensate the
difficulties produced by different diameters of the vehicle wheels, all fare registering
apparatus, can be made according to one standard model.
As many changes might be made in the construction and relative arrangement of
the different parts without involving a departure from the spirit of my invention,
I would have it understood that I do not limit myself to the exact construction
shown and described but consider myself at liberty to make such changes and
alterations as fall within the scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mauner the same is to be performed, I declare that what I
claim is :-
.
An adjusting device to be interposed between the fare registering apparatus and
the measuring wheel of the vehicle, consisting of a suitable rotating body (crank,
wheel, or the like) fitted to the vehicle and adapted to rotate with a speed corre-
sponding to the circumference of the measuring wheel of the vehicle, substantially
as and for the purpose set forth.
