Improvements in or relating to Motor Vehicles.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Bucking-
ham Street, Strand, W.C., London, Patent Agent, do hereby declare the nature
of this invention (a communication to me from abroad by the Firm of Heinle
and Wegelin, of Augsburg, in the Empire of Germany, Merchants), to be as
follows:-

These
This invention relates to improvements in or relating to motor vehicles.
improvements may be explained as applied for example to a tricycle, with motor
working, having essentially the same construction, as already protected under
Patent No. 7566 of 1896, only with the difference, that instead of the tandem
motor there is employed a one cylinder motor. This vehicle or tricycle com-
prises also the following essential parts and arrangements.
The benzene receiver, and the one cylinder motor, both form essential parts
of the frame construction as under Patent No. 7566 of 1896. The two bars
which connect the benzene receiver and the motor, are simultaneously the car-
riers for the magnetic inductor (lighting apparatus) the carriers which are con-
nected with the motor and the back axle, carry the driving gear consisting of
toothed wheels, comprising leather covered wheels and metal wheel gearing with
each other, the small wheel being always a leather covered wheel and the large
wheel the metal wheel, in order to obtain secure and quiet working. The driv-
ing gear is constructed in such a manner that 3 different speeds, that is, from
about 3 to 40 kilometers an hour can be obtained.
The machine is operated by means of friction coupling by means of levers run-
ning along the benzene receiver on each of which levers there is arranged a tooth
whereby they can be respectively secured in the sockets or recesses of sectors,
when adjusted.
In order to cause the motor to run quickly or slowly, there is arranged on the
top of the dome of the benzene receiver a regulating device, by means of which
the motor can be supplied with a small or large quantity of gas.
This construction consists of the arrangement in the gas tube of a throttle
valve, which is moved by an indicating lever moving over a scale in such a
manner, that the throttle valve opens or closes more or less, whereby the gas
mixture admission to the motor is regulated, and consequently there occurs
powerful or weak explosions.
For starting the motor easily there is arranged a releasing device, wherein the
out thrust crank pin is not displaced directly but indirectly by means of two
spiral springs, so that when the vehicle is stationary and at any position of the
motor the releasing device can be engaged or disengaged so that it is not neces-
sary for this purpose to turn the motor until one has found the place for the
engagement of the releasing device.
This motor tricycle can be used advantageously either by one or by two persons
with or without luggage etc.

I, REGINALD HADDAN, of 18, Buckingham Street, Strand, W.C., London, Patent
Agent (a communication to me from abroad by the Firm of Messrs. Heinle &
Wegelin, of Augsburg, in the Empire of Germany, Manufacturers), do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to motor vehicles and has for its object to provide simple
and effective means for controlling the speed of the motor and of starting from
rest.
The invention is more particularly applicable to motor vehicles or cycles of
the type described in the Specification to Patent No. 7566/ granted to Ludwig
Rub.
The invention consists of a variable speed gear, of means for starting the
vehicle from rest and avoiding the necessity of initially pushing the vehicle,
and of a regulating device for the supply of vapour to the motor..
The accompanying drawings illustrate the invention as applied to a motor
tricycle driven by a benzine motor similar in construction to that described in
the Specification to the Letters Patent before referred to except that in the pre-
sent illustrated construction the motor has a single cylinder and not tandem
cylinders, while the arrangement of cylinder, valves, reservoir, and the construc-
tion of the frame is similar.
Figure is an elevation of a complete motor cycle having the invention
embodied in its construction.
Figures 2 and 3 are partial plan and end elevation respectively corresponding
to Figure 1.
Figure 4 is a sectional elevation of the vapour regulating device.
As illustrated in the accompanying drawings the frame may be constructed
having a benzine reservoir a and motor cylinder provided to replace the upper
horizontal and the lower oblique members of the frame, and struts c are provided
upon either side of the benzine reservoir a with their upper extremities secured
thereto and having mounted between them a magneto electric inductor by means
of which a spark is periodically generated for the ignition of the explosive mix-
ture employed for driving the motor. Back stays el connect the extremity of
the benzine reservoir with the lower horizontal supporting members e of the
frame upon which the rear wheels are mounted as also the speed varying gear
which is to be hereinafter referred to. The steering wheel is mounted within a
head socket in the fashion of an ordinary tricycle.
The motor operates similarly to that described in the Specification to the
Letters Patent before referred to and the ignition is similarly effected by means
of an electro magnetic inductor whose armature spindle d is oscillated by means
of a tappet g mounted upon a gear wheel of deriving motion through gear from
the crank shaft k, the tappet engaging with an arm of a bell crank lever h
mounted upon the armature spindle and compressing or extending a spring
which on being released causes the rapid retraction of the armature and the
generation of the current, causing a spark in the combustion chamber of the
motor at the proper time.
The extremity of the crank shaft is formed to receive a key provided with
a cranked handle by means of which the crank shaft when the driving gear
is disconnected may be rotated thereby effecting the induction of a charge of

page_text: gas and air within the cylinder and its ignition by the means before described.
When the motor has thus commenced operation the handle is rapidly withdrawn
and on the connection of the driving gear the motor is propelled. It will thus
be understood that by such means the necessity of initially pushing the cycle
is obviated.
The driving gear is so provided as to enable the rider to regulate the speed
of the vehicle according to three different speeds varying, for example, from
four to thirty miles per hour.
The motor crank shaft k transmits motion to a secondary shaft k¹ by means
of spur wheels. The shaft carries loosely thereon three spur
wheels which form integral parts of clutches m¹ m² m³ respectively, the
sliding cones or complementary parts of which slide on feathers on the shaft k.
The spur wheels 11 12 13 gear respectively with wheels n n³ ³ on the driving
axle o of the cycle and the ratio of the different pairs of wheels is designed to
give three different speeds, for example, four, eighteen, and thirty miles per
hour, according to which pair is put in gear by its respective clutch cone. In
the drawing the pairs n³, 12 n2, 13 n³, give respectively the three speeds which
may be denominated slow, medium and fast. The clutches are operated by means
of levers sliding over racks q fixed to the benzine reservoir a. The lever p
actuates the slow speed clutch m₁ through a link g and bell crank rl, and the
lever 3 actuates both the medium and fast speed clutches m² m³ through a
link and bell crank 12. The slow speed clutch is put in or out of gear by
moving the lever pl to its extreme down or up position respectively, and the
fast and medium speed clutches are thrown in or out by similarly moving the
lever 3. When the lever p2 is in its central position the clutches m² m³ are out
of gear.
The supply of benzine to the motor is controlled by a throttle valve s in the
supply pipe t the said valve being operated by a handle u which passes over an
index dial upon a mixing valve mounted in a casing by arranging the
valves in such position the rider is enabled to conveniently set or regulate the
supply as required.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A motor cycle or vehicle having means for initially starting the motor,
means for varying the speed thereof, and means for regulating the supply of
vapour thereto substantially as hereinbefore described and illustrated.
2. In motor cycles or vehicles means for effecting change of speed consisting
of levers, links, clutches and gear disposed and operating substantially as herein-
before described.
3. In motor cycles or vehicles of the kind referred to in Claim 1 means for
initially starting the motor substantially as hereinbefore described and illus-
trated.
4. In motor cycles or vehicles means substantially as described and illustrated
for varying the supply of vapour to the motor.
