Improvements in Electricamy rope
A communication to me from EDMOND MARIE DOUMET DE SIBLAS, of 52, Rue
Richer, Paris, in the Republic of France, Engineer.
I, JULES PIERRE JUVENET, of 142, Palmerston Buildings, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to carriages, or vehicles such as cabs, propelled upon
ordinary roads by means of electricity. It has for its object novel methods of
constructing and operating such vehicles so that the electrically propelled part is
arranged on the front, or fore carriage, and is quite distinct from and independent
of the body or back part of the vehicle, which can be very quickly and easily
removed from the fore part, and replaced or changed.
Supposing that the invention is to be applied to such a vehicle as, for instance,
a fourwheeled cab, I connect the fore carriage, which carries the electrical driving
apparatus, to the body of the carriage by means of easily fixed and removed screws
or bolts which connect the upper part of the springs fixed above the fore carriage
to the frame below the driver's seat in front of and forming part of the main
body. By this arrangement any inconvenience from the vibration of the motor
is entirely prevented.
A vertical spindle surmounted by a steering wheel or handle is arranged in
front of and to the right of the driver, in a position where he can easily use it.
The lower end of the spindle is fitted with a toothed pinion gearing (preferably
with the intervention of a second pinion turning freely on a fixed stud) with a
toothed wheel upon the upper part of the fore carriage and concentric with the
pin upon which the latter turns, a disc or ring upon the fore carriage supporting
(preferably with the intervention of balls or rollers) a corresponding disc or ring
below the upper frame which rests upon it.
In this way the guiding or steering to the right or left is effected with perfect
ease and accuracy by the driver.
The starting and stopping of the motor is effected by a handle conveniently
placed under or close to the driver's seat, and by means of which he can instantly
cut off the current of electricity from the accumulators, or complete the circuit
through the motor, as required.
The electro-motor itself, which I make preferably of about four horse-power,
is firmly fixed upon the moveable frame of the fore carriage, above the axle of
the wheels. Its shaft is provided with a small toothed pinion, gearing with a
corresponding toothed wheel fixed upon a separate shaft upon which is also fixed
a small chain wheel which drives by means of a suitable chain the central chain
wheel of a differential bevelled wheel gear, of the ordinary well-known kind,
fixed upon the axle which carries at its ends the driving wheels under the fore
carriage of the vehicle. This axle is made in two parts, each part revolving in
separate bearings (preferably ball bearings) fixed under the fore carriage, so that

page_text: the wheels allow the vehicle to turn round corners, but are both driven by the
motor.
Instead of toothed wheels and chain, other suitable gear may be used, such as
belts pierced with holes, fitting upon pins on the circumference of the wheels.
Or, the axle of the driving wheels may be made in one piece instead of two, an
outer tubular axle surrounding it freely at one end, and having one of the wheels
fixed to it, the other wheel being fixed to the other end of the main inner axle.
The bevelled toothed wheels of the differential gear are fixed upon the main
axle and the tubular axle respectively, and a frame carrying the studs upon
which the bevelled pinions turn is also fitted upon the axles, and carries a spur
wheel, gearing with a small toothed pinion upon the spindle of the motor, with or
without intermediate toothed wheels between them to reduce the speed of the
axles and driving wheels. In this method of arrangement two bearings only for
the driving axle are necessary.
The accumulators in which the electricity is stored are placed in a box or
receptacle under the seat of the driver. Others may also be stored under the
seat of the main body of the carriage.
A voltmeter, and ammeter, are arranged in full view of the driver, so that
he is kept aware of the condition of the supply.
Brakes operating upon the back wheels are worked by the driver by means
of a foot lever.
By the novel method of construction described the driving and steering are
very certainly and easily accomplished, and by isolating the main body of the
vehicle from the fore carriage, except at the points where the former is bolted to
the springs upon the latter, and by making the front wheels the driving wheels
of the vehicle considerable advantage is obtained.
I do not confine myself to the precise details of construction and arrangement
of the several parts, which may be modified more or less as may be found
advisable.
A communication to me from EDMOND MARIE DOUMET DE SIBLAS, of 52, Rue
Richer, Paris, in the Republic of France, Engineer.
I, JULES PIERRE JUVENET, of 142, Palmerston Buildings, in the City of London,
Merchant, 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, and accompanying drawing, that is to say:
This invention relates to carriages, or vehicles such as cabs, propelled upon
ordinary roads by means of electricity. It has for its object novel methods of
constructing and operating such vehicles so that the electrically propelled part is
on the front, or fore carriage, and is quite distinct from and independent of the
body or back part of the vehicle, which can be very quickly and easily removed
from the fore part, and replaced or changed.
The accompanying drawing is in illustration of the invention, Figure 1 being

page_text: a side view, and Figure 2 a front view, showing the important parts of the
invention.
Supposing that the invention is to be applied to such a vehicle as, for instance,
a fourwheeled cab, as shewn in the drawing the body of the cab a, Figure 1,
being shown broken off, and the hind wheels and springs, which are of the
ordinary kind, being omitted, I connect the fore carriage, which carries the
electrical driving apparatus, to the body a of the carriage by means of easily fixed
and removed screws or bolts b, 61, which connect the upper part of the springs c
fixed above the fore carriage to the frame d below the driver's seat e in front of
and forming part of the main body a. By this arrangement any inconvenience
from the vibration of the electro-motor at f is entirely prevented.
A vertical spindle y surmounted by a steering wheel or handle his arranged
in front of and to the right of the driver, in a position where he can easily use
it. The lower end of the spindle is fitted with a toothed pinion i gearing (prefer-
ably with the intervention of a second pinion j (Figure 2) turning freely on a
fixed stud) with a toothed wheel k (Figure 2) upon the upper part of the fore
carriage and connected with the vertical pin upon which the latter turns, a disc
or ring upon the fore carriage supporting in the ordinary well-known way, pre-
ferably with the intervention of balls or rollers, a corresponding disc or ring
below the upper frame which rests upon it.
In this way the guiding or steering to the right or left is effected with perfect
ease and accuracy by the driver, and this steering is greatly facilitated when
anti-friction balls or rollers, as described, between the two discs or rings, are
used
This method of construction is more clearly shown in Figures 3 and 4, in
side view and in plan respectively.
The front part of the vehicle d is provided with fastenings screwed or bolted
to it at b, b, to which the ends of the springs c are connected, the centre of the
springs being bolted or screwed to the transverse beam D to the bottom of
which is firmly attached the upper disc or ring E. In the beam D) are also
arranged sockets or bearings for the toothed wheels i and j, of which is firmly
fixed to the lower end of the vertical steering rod g, whilst j is an intermediate
wheel turning freely on its axis between the wheels i and k with which it gears.
The lower disc or ring G is fixed upon a strong frame H, to which are con-
nected the supports connecting it with the fore carriage which carries the
electrical driving apparatus, (as shown in Figure 1).
The lower side of the upper ring E, and the corresponding upper side of the
lower ring G, have angular circular grooves in which run anti-friction balls as
shown, and the two discs or rings are held together with the proper force by
the pin or pivot having a nut at its lower end. The toothed wheel k is firmly
fixed to the lower disc G, so that when it is turned the fore carriage is also
turned with great ease, friction being reduced or prevented by the balls.
The starting and stopping of the motor is effected by a handle m conveniently
placed under or close to the driver's seat, and acting upon a switch or switches
by means of which he can instantly cut off the current of electricity from the
accumulators, or complete the circuit through the motor, as required.
The electromotor itself n, which I make preferably of about four horse-power,
is firmly fixed upon the moveable frame o of the fore carriage, above the axle
of the wheels, p,p. Its shaft is provided with a small toothed pinion r, gearing
with a corresponding toothed wheels fixed upon a separate shaft t upon which is
also fixed a small chain wheel which drives by means of a suitable chain the
central chain wheel w of a differential bevelled wheel gear a, of the ordinary
well-known kind, fixed upon the axle y which carries fixed upon its ends the
driving wheels 2, p under the fore carriage of the vehicle. This axle is made in
two parts y and y¹, each part revolving in separate bearings z (preferably ball
bearings) fixed under the fore carriage, so that the wheels allow the vehicle to
turn round corners, but are both driven by the motor n.

page_text: Instead of toothed wheels and chain, as above described and shown, other suit-
able gear for the same purpose may be used, such as belts pierced with holes,
fitting upon pins on the circumference of the wheels. Or, the axle of the
driving wheels may be made of one inner axle having one of the wheels fixed
upon it, an outer tubular axle surrounding it freely at one end, and having the
other of the wheels fixed to it.
The bevelled toothed wheels of the differential gear are fixed upon the main
axle and the tubular axle respectively, and a frame carrying the studs upon which
the bevelled pinions turn is also fitted upon the axles, and carries a spur wheel
gearing with a small toothed pinion upon the spindle of the motor, with or with-
out intermediate toothed wheels between them to reduce the speed of the axles
and driving wheels (as shown in Figure 2). In this method of arrangement two
bearings only for the driving axle are necessary.
The accumulators in which the electricity is stored are placed in a box or
receptacle under the seat e of the driver. Others may also be stored under the
seat of the main body a of the carriage.
An ammeter 1, and voltmeter 2, are arranged in full view of the driver, so
that he is kept aware of the condition of the supply.
Brakes operating upon the back wheels are worked by the driver by means
of a foot lever, at 3.
By the novel method of construction described the driving and steering are
very certainly and easily accomplished, and by isolating the main body a of
the vehicle from the fore carriage, except at the points b, b' where the former is
bolted to the springs upon the latter, and by making the front wheels
the driving
wheels of the vehicle considerable advantage is obtained.
P
I do not confine myself to the precise details of construction and arrangement
of the several parts, which may be modified more or less as may be found
advisable.
For instance, devices of any of the ordinary well-known kinds may be used
for varying the speed of the driving wheels as desired.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In electrically propelled road vehicles, the combination of an electro-motor
carried upon the fore carriage of the vehicle, and driving the two front wheels
which serve as driving wheels, by means of toothed gear and chain wheels, the
fore carriage and electro-motor being entirely distinct from the body of the
vehicle except at the points where the springs of the fore carriage are screwed
to the front of the vehicle, substantially as described and illustrated.
2. In the electrically propelled vehicle, described in Claim 1, the method of
connecting the lower part of the fore carriage which carries the electro-motor and
the bearings for the axles of the fore wheels, to the upper part, which carries the
springs to which the front of the body of the vehicle is screwed, by means of
parallel discs or rings, having between them antifriction balls or rollers, the
steering being effected by a wheel or handle upon a spindle turning in bearings
carried by the upper part of the fore carriage, and having upon its lower end a
pinion by which a toothed wheel upon the lower part of the forecarriage is caused
to turn in one or other direction, substantially as described.
