Improvements in and relating to Motor-cars.
I, ADAM ÚPEL, of Rüsselsheim on the Main, Germany, Manufacturer, do hereby
declare the nature of this invention and in what the manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
:-
The object of these improvements consists in a number of separate mechanisms
which in their totality guarantee a most simple and perfectly safe working of the
vehicle.
The present car has two ordinary strap pulleys 1 and 2 which are driven by
crossed straps and backward running pulleys 5 actuated by an uncrossed or open
strap. In order to obtain a most uniform distribution of the entire driving
mechanism the two cylinder motor actuating a common cranked axle is provided.
with one cylinder 6 and one 7 on each side of the interior of the car arranged in
such a manner that the chain wheel 8 of the rear axle 9 arranged thereunder can
be turned freely by the driving chain 10 arranged in the centre of the lower
frame.
The chain 10 drives the rear axle 9 Fig. 2 and when driven forward turns with
it the two rear wheels 11a and 11b whose naves 12ª and 12b are rotatable on the
central axle and are provided with coupling teeth. When driven backwards the
chain wheel 8 which is loose on the axle pushes the two sleeves 14ª and 14b aside,
they being so arranged that tliey can be moved laterally but cannot be turned
upon the axle. The coupling teeth of the chain wheel 8 and the sleeves 14ª and 14b
being higher than those of the naves 12ª and 12b the latter are coupled by friction
and are prevented from sliding, consequently the car will run backward.
The coupling box 14° (between the sleeves 14ª and 14b) is placed on the central
axle on which it is rotatable whilst the said sleeves 14ª and 14b are not rotatable
but can be displaced laterally on the axle. If the middle coupling box 14° is
rotated backwards for instance, by the chain 10 and toothed wheel 8 (Fig. 1) the
two sleeves 14ª and 14b will move sideways so that they are pressed against the
coupling members 13ª and 13b. Thus all the coupling boxes are joined by friction,
and form one whole with the central axle as the teeth of 14° and 14ª and 14b are
higher than those of 13 and 13b. Between the coupling members 13ª and 14ª,
and 13 and 14b are intermediate spaces less than the height of the coupling teeth
of the latter but greater than the height of the teeth between 13ª and 13b and
the naves.
If the middle coupling box 14° is driven forwards the teeth thereof slide
against those of 14 and 14b until they gear because the sleeves 14 and 14b are
pressed by the springs against 14°.
If the car is driven in a curve, the outside wheel can always be the foremost
as the springs allow the coupling members 13 and 13b to be pushed sideways
whereby the teeth firmly fixed to the wheel nave can slide over the teeth of 13
and 136 until the car again runs straight forward and the revolutions of the car
wheels are regular.
This construction avoids a differential gear, allows the use of an undivided axle

page_text: and the latter is equally loaded throughout when driven whilst with differential
gears only certain teeth have to bear the whole pressure.
The means of throwing into gear and out of gear of the two straps for the
forward movement is represented in Fig. 4. The levers 15 and 15 have on the
front ends strap forks 16 and 16. At their rear ends the said levers 15ª and 15b
are pivoted on a bolt 17 and are actuated by a double lever 18 which has at its
end pins 19 and 19 engaging in slots 20 and 20 in said levers so that only
one of the levers 15 or 15 is moved whilst the other remains stationary which
is obtained by the peculiar shape or curvature of the slots. The lever 15 can
be guided from loose pulley to fixed pulley 2b. The double lever 18 is
actuated from near the carriage seat by turning the vertical rod 21 (Fig. 3)
in the one or other direction.
The pulleys 1, 2 and 5 receive their movement from the crank shaft and transfer
their power by means of the chain 10 to the rear axle.
The explosive mixture in the double motor is ignited in the following manner:
In order that the induced current, that is to say the igniting spark may not
prematurely pass between the flat springs, 22, 23, 24, a turning contact 25 is
arranged which is put into operation by the crank shaft by each revolution of
the same, but spring 22 must be put into circuit with spring 23, or spring 23
with spring 24 before the contact 25 is closed. By a revolution of the contact
springs 26, 27 round the crank disc 25, consisting of hard rubber with metal
inlays for closing of the circuit, the moment of ignition can be changed as desired
from inside the carriage by means of a suitable draw rod. The positive pole 28
of the accumulator 29 is connected with the contact spring 26. From the other
contact spring 27 the connection goes to the binding clamp 30 of the inductor 31
and from binding clamp 32 to the negative pole 33 of the accumulator 29.
The induced current passes from the binding clamp 34 of the bobbin 35 to the
middle contact spring 23 of the board 36. The second binding clamp 37 of the
bobbin 35 is connected with the metal mass of the machine, in this case with
the frame 38 by the binding clamp 39. From the spring 22 connection is made
to the igniter 40 and from the spring 24 to the igniter 41.
By each rotation of. the crank shaft in consequence of the reciprocal putting
into circuit of the rocking arm 42 (which receives its movement from the toothed
wheel 43 and which carries with it the spring 23) the latter is guided alternately
to contact 22 and to contact 24. The larger toothed wheel 43 has twice as many
teeth as that on the crank shaft.
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:-
In a motor car the following improvements separately or in combination.
1. A driving device for motor vehicles consisting of two explosion motors 6
and 7, aranged one on each longitudinal side of the car interior, both working
simultaneously in the same direction on a common crank shaft, and a chain 10
arranged between the driving pulleys on the lower frame of the car, driving the
rear axle 9 for the purpose of procuring the most favorable distribution of the
weight of all parts and an equal loading of the crank shaft bearings.
2. A device for the backward movement of motor cars wherein the driving
wheels 11 and 11 are each connected by a separate toothed coupling 13ª 13
allowing the rotary advance of either wheel before the other with the driving
axle 9; the gear wheel 8 driven by the motor and loosely mounted on the
driving shaft 9 being provided on both sides with coupling teeth which gear with
similar teeth of sleeves 14 and 14b arranged movably on the driving axle each
side of the wheel 8, and which are of such height that with the backward
turning of wheel 8 although the sleeves 14" and 14 are displaced any sliding
of the coupling teeth of one part over those of the other part is prevented in
order to make the backward rotation of the driving axle possible.

page_text: 3. A strap engaging and disengaging device for motor vehicles cha
by two rocking arms 15 and 15 fastened on the bolt 17 and provided with
curved slots 20 and 20 serving as guides for pins 19 and 19b on a double lever 18
for the purpose of a reciprocal displacement of the strap forks 16 and 16b by
means of the vertical turning rod 21 and the resulting displacement of the
arms 15 and 15b by means of the slots 20ª and 20b.
4. An electric igniting device for two cylinder explosion motors with alternate
opening and closing of the induced circuit by means of a rocking arm 42
influenced by eccentric or like motion and three contact springs 22, 23, 24
insulated on the board one from another, whereof the middle spring 23 is brought
into electrical connection by the arm 42 alternately with the one and other con-
tact 22 or 24 for the purpose of reciprocal delivery of ignition current to the one
or other igniter in connection with the respective spring.
