I, RUDOLF HAGEN, of 32, Hohenstaufenring, of Cologne on the Rhine, Province
of the Rhine, German Empire, Merchant, do hereby declare the nature of this
invention to be as follows:-
The present invention relates to improvements in motor vehicles and comprises
specially the means for changing the speed of the vehicle, the arrangement
of the fly-wheel and the construction of the vapourizer. The means for changing
the speed of the vehicle act independently of the motor and by exclusive employ-
ment of a lever-mechanism in such a manner, that the force is used in the most
profitable manner and that the vehicle runs with a constant velocity. The fly-
wheel is horizontally arranged, in order to gain a greater quantity of effective
space. The vapourizer is so constructed that an occasional access of fire to the
outside does not effect an explosion and that the gas is always kept under a constant
pressure.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the several views, and
in which:
Fig. 1 is a side view of the motor vehicle.
Figs. 2 and 3 show detached parts.
Fig. 4 is a plan of the motor vehicle.
Fig. 5 is a detached part.
Fig. 6 is a rear view of the motor vehicle.
Figs. 7, 8, 9, 10 & 11 show detached parts of the motor vehicle.
Fig. 12 is a modification of the device for changing the speed of the motor
vehicle.
In the construction shown in Figs. 1, 4 & 6 is used a twin cylinder engine,
the cylinders a a' of which are placed to an angle to each other. The connecting-
rods are attached to the common crank-shaft c, which runs in vertical bear-
ings of the frame d. A toothed wheel f, which is fastened on the crank-shaft c
engages with the toothed wheel g, transmitting its power to the horizontally
turning fly-wheel h. The movement of the toothed wheel f is transmitted to the
vertically oscillating slotted arm a by means of the connecting rod i, the cross-
head and the connecting rod m.
In the slot of the slotted arm n slides a block p that is pivotally connected
with the slide block . The latter slides in the slotted arm of a double armed
lever g', the ends of which are pivotally connected with the rods r r¹, so that
when the arm n oscillates the lever qq, which turns around 8, oscillates also
and the rods rr¹ alternately move the driving levers tt. The latter are movably

page_text: arranged on the hind-axle-tree of the vehicle and act in the well known manner only
in one direction. It is clear that by means of the described parts fmnq q'r r¹t t₁ a
continual turning of the hind-wheels i.e. the driving wheels of the motor vehicle
takes place.
A lever v, movably arranged on the joint-lever, is movably connected with the
common pivot of the two slide-blocks p. The arm w of this lever may be held
in different positions by means of the ratchet and pawl (not shown in the
drawing).
By dislocating of the slide block within the slotted arm n the effective length of
the latter is diminished or increased. As the slide-block p is connected with the
slide-block p¹, the latter is also removed and the effective length of the same is
correspondingly changed. The displacement of the slide-blocks is effected by
means of the hand-lever w. If the blocks are pushed up, the effective length of
the lever P is diminished while that of the lever q is increased, whereby a double
diminution of the stroke of the driving-lever and a decrease of the velocity of the
vehicle is attained.
The slide-block being pushed down, the effect is diametrically an opposite one.
So the velocity of the vehicle may be controlled and the latter may even be stopped.
For this purpose the slot of the lever n is extended beyond its pivot o, so as to
permit to bring the slide-block in a position in which its pivot lies conaxially with
the pivot o of the lever n (Figs. 1, 9 & 11). In this position of the slide-block P
the oscillation of the lever n is no more transmitted to the lever g, so that the hind-
axle-tree is stopped independently of the working of the motor.
Instead of extending the slot of the lever n beyond its fulcrum, the slide-block
may be provided with a flange (Fig. 10) with which the end of the lever vis
movably connected. Said flange is brought for the purpose of stopping the vehicle
in such a position that its pivot lies conaxially to pivot o.
In Fig. 12 is shown à modification of the lever-mechanism. In this modification
the motor has only one cylinder and a vertical fly-wheel but it will be clear from
the following description, that its lever mechanism may also be employed in
connection with the above described motor.
In Fig. 12 represents the slotted-arm operated by the crank-shaft, which arm
may oscillate on the fixed bolt g. 12 is a slotted arm, that may oscillate on the
fixed bolt m2.and that moves by means of its cross-arm the rods a³ and 63. The
latter act alternately on the driving lever in the same manner as before described
with reference to Fig. 1, 4 and 6.
The slotted arms f2 and 12 are provided with slide-blocks i and h³ respectively,
that are connected with each other by means of a traverse 2 pivotally fastened to
the said slide-blocks. The traverse may be vertically raised and lowered by means
of the lever p².
When the traverse is raised, the stroke of the driving lever is increased but
when it is lowered, the stroke is reduced, so that the velocity of the vehicle is
accordingly increased or reduced without dependence of the motor.
Figs. and S show a detached view of the cross-head-guides for the rods m and i.
As the rod i oscillates in the horizontal and the rod m in the vertical direction, the
cross-head is constructed in a peculiar manner, in order to place the working-point
into the centre. For this purpose the forked end of the rod i oscillates on a vertical
bolt, that connects the two sliding surfaces of the cross-head. Between the two
legs of the fork the rod m is pivotally connected with said bolt, so that it may
oscillate in a plane being perpendicular to the plane in which the rod i oscillates.
Much effective space is gained in consequence of the above described horizontal
arrangement of the fly-wheel and this effective space is still increased because, by
means of the gearing fg, the fly-wheel is allowed to run with high speed and may
therefore have a small diameter.
Fig. 2 shows the ball-bearing of the axle of the toothed wheel f.
The construction of the vapourizer is shown in Fig. 5 and Figs. 1, 4 and 6.
The benzine is vapourized in the container A by means of the serpentine-nine B.

heating the benzine by means of a burner. The vapourized benzine passes through
a pipe H and a regulating valve G to the reservoir D. Here it is kept under a
constant pressure by means of the piston F, that when the pressure of the gas
contained in the reservoir should rise, is raised and closes the valve G by means of
the lever K K'. When the gas of the reservoir D) has reached again the normal
pressure, the piston F is lowered again by means of a spring or weight and the
valve G is opened again so that new gas may pass through the pipe H into the
reservoir D.

COMPLETE SPECIFICATION.
Improvements in Motor Road Vehicles.
I, RUDOLPH HAGEN, of 32, Hohenstaufenring, of Cologne on the Rhine, Province
of the Rhine, German Empire, Manufacturer, do hereby declare the nature of this
my 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 motor-driven vehicles and consists firstly of an improved
variable speed gearing for transmitting the power from the motor to the driving
wheels of the vehicle, and secondly of an improved arrangement of the fly-wheel.
According to the first part of my invention I provide a rocking beam operated
from the main-shaft by means of a rocking lever and rods connecting both ends
of such beam with a clutch mechanism being alternately moved by the connecting-
rods of the rocking beam in such a manner that a continual rotation is obtained
although only one clutch-mechanism and only one set of connecting-rods be
provided. The stroke of the rocking beam can be increased or diminished by
increasing or diminishing the effective length of the rocking-lever operating the
beam respectively so that the velocity of the vehicle may be changed independently
of the motor.
According to the second part of the invention I provide means for increasing
the rotating speed of the fly-wheel such, as toothed-wheels or friction-disks trans-
mitting in an increased degree the motion of the crank-shaft to the fly-wheel
which is secured to a separate shaft. Thus, the effect of a heavy fly-wheel attached
to the crank is obtained by means of a fly-wheel running with high speed and
having a less weight. The latter advantage is most important for motor-driven
vehicles.
In order that the said invention may be clearly understood and readily carried
into effect I will proceed to describe the same by aid of the accompanying drawings
in which:
Fig. 1 is a side-view showing the variable-speed gearing together with the clutch-
mechanism and the arrangement of the fly-wheel.
Fig. 2 shows in side-elevation the rocking-beam connected with the rocking-
lever.
Fig. 3 is a cross section thereof.
Fig. 4 is a side-view of the clutch-mechanism, and

page_text: Fig. 5 is a front-view of the same partly in section.
"The movement of the crank-shaft è is transmitted to the vertically oscillating
slotted lever n by means of the small connecting rod i. In the slot of the slotted
lever n slides a block p that is pivotally connected with the slide-block p¹. The
latter sides in the slotted arm of a rocking-beam qq', the ends of which are linked
to the rods rr so that when the lever n oscillates the beam qq which turns
around s oscillates also and the rods rr alternately move the levers tt which act
upon the driving disk a.
The latter is rigidly attached on the driving-axle of the vehicle. It is provided
with an annular projection b on either side along which the clutches d are adapted
to slide by means of their grooves f. The interior ends of the clutches d are seized
by the corresponding noses g of the levers tt' respectively when the latter are
moved in that direction in which the driving-axle is to be rotated. As soon as
the noses g push against the interior ends of the corresponding clutches & the latter
turn around that part of the annular projection 6 which lies within the grooves f,
in such a manner that a strong friction arises between the clutches and the annular
projection and, in consequence, the driving-disk a will be rotated. When the
levers are moved in the reverse direction the springs h fastened to pins k and
to the corresponding clutches respectively will withdraw the clutches which then
can freely slide along the annular projection as they are seized by the springs
near to the said projection. Of course, the said clutches, noses and springs are
provided on either side of disk a as well as the projections b. It is obvious that a
continual rotation of disk a will take place as the levers tt' act alternately upon
the clutches.
v
A lever viz. movably connected with the common pivot-bolt of the two slide-
blocks pp. By means of a set of levers, the lever is connected with the handle w
which may be held in different positions by the ratchet and pawl y. By move-
ment of the slide block p within the slotted lever n the effective length of the latter
may be diminished or increased. As the slide-block is connected with the slide-
block p, the latter is also removed and the effective length of the arm
is corre-
spondingly changed. The displacement of the slide-blocks is effected by means
of the hand-lever w above-mentioned. If the blocks are pushed up a decrease of
the velocity of the vehicle is attained, by pushing the slide-blocks down, the speed
is increased without dependence of the motor.
The toothed-wheel a is secured to the crank-shaft c and gears with the small
toothed-wheel u rigidly attached to the shaft of the fly-wheel m which, thus, runs
with high speed.
By this arrangement, the most important advantage is obtained that the weight
of the fly-wheel is essentially diminished without increasing the velocity of the
motor. Hitherto, in motor-driven vehicles the inconvenience of a heavy Hy-wheel
has been done away by providing a motor of high speed, although it is generally
known that such motors are not suitable to this purpose. At the same time, by
my arrangement the motor can be more easily set to work.
Friction-disks or the like may be employed instead of the toothed-wheels
and u.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
:-
1. In motor-vehicles the combination of a set of levers operated from the motor
with a clutch-mechanism operating the driving-axle of the vehicle, and two rods
connecting the said set of levers with the clutch-mechanism in such a manner
that the driving-disk of the clutch-mechanism being alternately operated by the
rods is caused continually to rotate, substantially as described.
2. In a motor-driven vehicle a variable speed gear having a clutch-mechanism
for continually acting upon the driving-axle of the kind referred to substantially
as described.

page_text: 3. In a motor-driven vehicle the arrangement of the fly-wheel in such a manner
that it rotates with a greater speed than that of the crank-shaft substantially as
and for the purpose described.
4. My improvements in motor-driven vehicles, substantially as herein before
described and as shown in the accompanying drawings.
