the side wall of the car and extends into the same far enough to allow a bevel gear
wheel 8 to be firmly connected to it. The bevel gear wheel 9 which is placed
firmly on the shaft 10, engages with the bevel gear wheel 8. The shaft 10, is
journalled in the brackets 11 and 12 on the side wall of the car, and carries on its
other end the bevel gear wheel 13. The bevel gear wheel 14 which is secured to
the shaft 15 engages with the wheel 13. The shaft 15 is journalled in the
brackets 16 and 17 of the front wall of the car. On the other end of the shaft is
firmly secured the bevel gear 19 which engages with the bevel gear wheel 20.
The bevel gear wheel 20 is secured firmly on the shaft a of the advertising apparatus,
which shaft a is journalled in the brackets 21 and 22 of the wall 23, and carries
the worm b. This worm is in gear with the worm wheel d, which is firmly secured.
on the axle c. The axle & is journalled in the wall 23 and is firmly connected with
a toothed wheel e. Behind the toothed wheel and arranged so as to turn on the
axle c is located the collar 24 of a plate t, which is furnished with studs on pegs 25
and 26, on which the toothed wheels fg are journalled. The toothed wheels fy
stand alternately in connection with the toothed wheel h, which is journalled on the
axle upon the wall 23. With the toothed wheel a disc k is firmly fastened,
which near the periphery of the same is supplied with bored holes or dove-tailed.
grooves. In certain of the bored holes 7 movable pegs m are placed which
are held firmly in place by screws 27 set radially into the periphery of the disc.
Over the pegs m of the disc K a contact spring n extends which is fastened on the
bracket 28 of the wall 23. On the bracket 28 a second contact spring o is
fastened, whose free end lies over the free end of the contact n at a certain
distance from it. On the contact spring n is fastened a contact point 29 while on
the contact spring o is a contact point 30, and to these contact points 29 and 30
are joined the wires 31 and 32 which starting out from the battery 50 are led

arm 8. On the pin r the bevel wheel t is firmly placed with which the wheel 24
seoured on the shaft a, engages. Fastened to the bevel wheel t is the front
wheel which engages with the front wheel v. The latter is firmly connected to
the axle w which is placed so as to turn in the arms of the armature 9. The
arm has a slot in which the friction wheel which is fixed firmly on the
axle w is placed. The friction wheel v engages at a definite time with the friction
wheel which is fixed firmly on the rotary axle a', of the wall 23. With the friction
wheel z is firmly connected a bevel wheel 61, which engages with the bevel wheel c¹.
The bevel wheel e' is fixed firmly on a shaft d' which is journalled in brackets 351
and 36 of the wall 23. On the axle d' the mutually connected bevel wheels e¹ f¹,
are fastened so as to shift, so that either the bevel wheel el, may engage with the
bevel wheel g' or the bevel wheel f' with the bevel wheel /¹.
The bevel wheel ¹ has formed on its collar or hub with a groove 37, into which
pins 38 are inserted which project from both links or arms of the fork o'. The
fork o' pivots on the pin m² of the wall 23, and its free arm n¹ is fastened by a
joint with the rod q', which is fastened so as to turn on the angular or bell crank
lever pl.
This angular lever pl pivots on the pin o' of the wall 23 and is formed with a
slit 39, by means of which it moves on the pin 40 by which the lever pl is fastened
to the leading rod r'. The rod is placed so as to be movable longitudinally in
the brackets 21 and 22 of the wall 23 and is firmly fastened to the continuation 41
of the rods which is screwed into the collar or boss 24 of the disc . The rod s'
is fastened to the bracket 21 by means of a spiral spring.
12
The arm n' of the fork o' rests on an eccentric upon a pin 42, which is mounted
in a bracket 43 on the wall 23. To the pin 42 is connected a cranked handle g².
Under the collar of the bevel wheel 1 is arranged a spiral spring 44, which presses
against said wheel. The bevel wheels g¹¹ are fixed firmly on the shafts i¹ k¹,
which are journalled in the brackets. y on the wall 23.
About the shaft k' are rolled various advertisements, placards or the like united
into a band 45. The free end of the band 45 is carried over the roller a' which is
journalled in brackets 46, 47 on the wall 23 and over the roller which is
journalled in the brackets a¹y to the shaft and is there fastened. On the
bracket 48 upon the wall 23 is found a contact point . Over this is arranged,
upon the same bracket a contact spring d provided with a contact point c³ whose
free end reaches over the placard band edge and presses on the contact point 62
serving the purpose of closing the electric current. From the contact points
and care carried the wires 49 and 50s which connect as a conductor the battery 50
with an electric signal contrivance 51. On the placard band edge are buttons ³ at
certain distances according to the length of the various placards.
The advertising apparatus is enclosed by a case 52 the front wall of which is cut
away. The apparatus works as follows:-
:-
If on the route taken by the car, for example, eight store owners wish to have
their placards exhibited by the car, the disc k is first provided with the same number,
that is with 8 pegs m and distances left between the pegs proportional to the
distances of the eight stores from one another. Then the band formed of the
various placards is provided with 8 buttons which are fastened on the edge of
the band between every two placards. Then the band is so placed that the first
of the buttons e finds its place under the free end of the contact spring d³ which
is raised by the button and removed from the contact point 62; the current which
works the signal contrivance is then broken.
Now, when the car begins its journey, the revolution of its wheel 2 by means of
bevel gear wheels 8 and 9, shaft 10 bevel wheels 13, 14 shaft 15, bevel wheels 19, 20
communicated to shaft a, which latter partly conducts the motion in a highly
retarded degree by means of the worm b, worm wheel d, cog wheel e, cog wheel f
to cog wheel and disc k, and partly, however, in undiminished rapidity imparts it
by means of bevel wheels u, t, cog wheels u v to the friction wheely. Now if the

page_text: car approaches the first store, whose placard should then be visible in the car the
disc has turned itself, so that the first of the pegs m of the same touches
the contact spring n and raises the latter, while this peg m glides under the
contact spring n, in the further revolution of the disc k. The contact spring n
is raised until it touches the contact spring o.
As
The wires 31, 32 are thereby made to connect as conductors and an electric
circuit formed, which excites the electro-magnet p. The armature q of the last
mentioned is pulled and the swinging of the same which then takes place about
the pin r, brings the friction wheel y into contact with the friction wheel z in
consequence of which the latter is rotated and sets in motion by means of bevel
wheels & the shaft d' which by means of bevel wheels el gl moves the placard
barrel in such a manner that the placard band 45 unrolls itself on the same.
this unrolling begins the button 3 of the placard band glides away from the
isolated end of the contact spring d³, the latter falls down on the contact point b²,
the wires 49 and 50* are connected as conductors and excite the electro-magnet of
the signal apparatus 51 whose call warns the passengers of the change taking place
in the placard. Meanwhile the peg m of the disc has removed itself from the
contact spring n so that this can return to its position of rest and in doing so it
breaks the current which excited the electro-magnet p, the armature 9 falls from
the latter and the friction wheel y moves out of contact with the friction wheel z
in consequence. The latter remains accordingly at rest and stops in this way the
motion of the placard barrel i¹ on which during its revolution the first placard of
the placard band wound on the barrel has unrolled itself. During this unrolling
a second button e' of the placard band 45 has glided under the isolated end få of
the spring and the same breaks immediately the current which influences the
signal apparatus 51 and silences the latter. When the car approaches the second
store desiring advertisement, the disc k has gradually turned itself until the second
of the pegs m of the same comes under the contact spring n, thus again closing the
circuit and repeating the operation just described. When the car reaches its last
station, the placards are all unrolled from the barrel k' onto the barrel i'. At the
beginning of the journey back, now, the placards are to appear in the car in reversed
order corresponding to the reversed sequence of the places of business. This is
accomplished by a shifting of the parts by the cranked handles 92 and the
eccentric . By means of this handle the eccentric is caused to operate the bevel
gear wheels elf to cause the bevel gear e¹ to become disengaged from the bevel
gear gl and at the same time cause the bevel gear f¹ to engage the bevel gear A¹,
and also, through the rod 9' and bell crank lever drawing on the rod and arin s
moves the cog wheel h out of gear and thus reversing the direction of movement of
the connected parts.

Improvements in Advertising Apparatus.
I, KARL KÖHLER of Berlin, Bülowstrasse 44 in the Kingdom of Prussia and
German Empire, 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 :-
The advertising apparatus hereinafter described is designed to effect the
continuous and automatic display of business advertisements etc., in a car as it
approaches the places of business to which the advertisements refer.

partly broken away.
The advertising apparatus is arranged as follows:
-
The sprocket wheel 3 is firmly connected to the hub 1 of the wheel 2 of the car
or other vehicle. By means of the sprocket chain 4, the wheel 3 is connected with
the sprocket wheel 5, so that the motion of the sprocket wheel 3 is imparted to the

which is secured
wheel 8 to be firmly connected to it. The bevel gear wheel
firmly on the shaft 10, engages with the bevel gear wheel 8. The shaft 10, is
journalled in the brackets 11 and 12 on the side wall of the car, and carries on its
other end the bevel gear wheel 13. The bevel gear wheel 14 which is secured to
the shaft 15 engages with the wheel 13. The shaft 15 is journalled in the
brackets 16 and 17 on the front wall of the car. On the other end of the shaft is
firmly secured the bevel gear 19 which engages with the bevel gear wheel 20. The
bevel gear wheel 20 is secured frmly on the shaft a-of the advertising apparatus,
which shaft a is journalled in the brackets 21 and 22 on the wall 23, and carries
the worm b. This worm is in gear with the worm wheel d, which is firmly secured
on the axle c. The axle c is journalled in the wall 23 and is firmly connected with
a toothed wheel e. Behind the toothed wheel e and arranged so as to turn on the
axle c is located the collar 24 of a plate t, which is furnished with studs or pegs 25
and 26, on which the toothed wheels fg are journalled. The toothed wheels f g
stand alternately in connection with the toothed wheel h, which is journalled on
the axle upon the wall 23. To the toothed wheel a disc k is firmly fastened,
which near the periphery of the same is formed with bored holes or dove-tailed
grooves. In certain of the bored holes / movable pegs m are placed which are
held firmly in place by screws 27 set radially into the periphery of the disc. Over
the pegs m of the disc k. a contact spring n extends which is fastened on the
bracket 28,on the wall 23. On the bracket 28 a second contact spring o is fastened,
whose free end lies over the free end of the contact spring n at a certain distance
from it. On the contact spring n is fastened a contact point 29 while on the
contact springo is a contact point 30, and to these contact points 29 and 30 are
joined the wires 31 and 32 which, starting out from the battery 50, are led to the
electro-magnet p. The electro-magnet p is fastened to the wall 23 by means of
the brackets 33 and 34. The armature of the electro-magnet swings on a rotating

pin is firmly fixed the bevel wheel t with which the wheel u secured on the
shaft a engages. Fastened to the bevel wheel t is the front wheel u° which engages
with the front wheel v. The latter is firmly connected to the axle w which is
placed so as to turn in the arms of the armature q. The arms has a slot in
which the friction wheel which is fixed firmly on the axle w is placed. The
friction wheel engages at a definite time with the friction wheel which is fixed
firmly on the rotary axle a' of the wall 23. With the friction wheel is firmly
connected a bevel wheel ', which engages with the bevel wheel c. The bevel
wheel c is fixed firmly on a shaft d' which is journalled in brackets 35 and 36 of
the wall 23. On the axle d¹ the mutually connected bevel wheels el, are mounted
movably so that either the bevel wheel ¹ may engage with the bevel wheel g' o
the bevel wheel f¹ with the bevel wheel h'.

The bevel wheel f¹ has formed on its collar or hub a groove 37, into whiel
pins 38 are inserted which project from both links or arms of the fork o'. Th
fork of pivots on the pin m¹ on the wall 23, and its free arm n' is fastened by a join
with the rod which is fastened so as to turn on the angular or bell crank lever p

page_text: This angular lever p¹ pivots on the pin o² of the wall 23 and is formed with a
slit 39, by means of which it moves on the pin 40 by which the lever p' is fastened
to the leading rod 7. The rod r is placed so as to be movable longitudinally in
the brackets 21 and 22 of the wall 23 and is firmly fastened to the continuation 41
of the rods which is screwed into the collar or boss 24 of the disc t'. The rod ³¹
is fastened to the bracket 21 by means of a spiral spring.
The arm n of the fork o¹ rests on an eccentric upon a pin 42, which is mounted
in a bracket 43 on the wall 23. To the pin 42 is connected a cranked handle g²..
Under the collar of the bevel wheel is arranged a spiral spring 44 which
presses against said wheel. The bevel wheels g'h' are fixed firmly on the shafts i¹³,
which are journalled in the brackets ¹y on the wall 23.
.8
About the shaft are rolled various advertisements, placards or the like united
into a band 45. The free end of the band 45 is carried over the roller a which is
journalled in brackets 46, 47 on the wall 23 and over the roller which is journalled
in the brackets a¹y to the shaft and is there fastened. On the bracket 48 upon
the wall 23 is formed a contact point 2. Over this is arranged, upon the same
bracket a contact spring d provided with a contact point of whose free end
reaches over the placard band edge and presses on the contact point serving the
purpose of closing the electric current. From the contact points 3 and ² are
carried the wires 49 and 50 which connect as a conductor the battery 50 with an
electric signal contrivance 51. On the placard band edge are buttons 2 at certain
distances according to the length of the various placards.
The advertising apparatus is enclosed by a case 52 the front wall of which is cut
away. The apparatus works as follows:-
If on the route taken by the car, for example, eight store owners wish to have
their placards exhibited in the car, the disc k is provided with the same number of
pegs m that is with 8, and distances are left between the pegs proportional to the
distances of the eight stores from one another. The band formed of the various
placards is provided with 8 buttons e² which are fastened on the edge of the band
between every
two placards. Then the band is so placed that the first of the
buttons e is situated under the free end f' of the contact spring which is raised
by the button e² and removed from the contact point 62; the current which works
the signal contrivance is then broken.
• Now, when the car begins its journey, the revolution of its wheel 2 is
communicated by means of bevel gear wheels 8 and 9, shaft 10 bevel wheels 13, 14,
shaft 15, bevel wheels 19, 20 to the shaft a, which latter partly transmits the
motion in a highly retarded degree by means of the worm b, worm wheel d, cog
wheel e, cog wheel to cog wheel 4 and disc k, and partly at the same speed, by
means of bevel wheels u, t, cog wheels to the friction wheel y. Now, if the
car approaches the first store whose placard should then be visible in the car,
the disc will have turned itself, so that the first of the pegs m of the same touches
the contact spring n and raises the latter, while this peg m glides under the contact
spring n,
in the further revolution of the disc k, the contact spring n is raised until
it touches the contact spring o.
The wires 31, 32 are thereby connected and an electric circuit formed, which
excites the electro-magnet p. The armature 9 of the last mentioned is raised and
the swinging of the same which then takes place about the pin ", brings the
friction wheel y into contact with the friction wheel z in consequence of which the
latter is rotated and sets in motion, by means of bevel wheels 'c¹ the shaft d',
which by means of bevel wheels el g' moves the placard barrel i¹ in such a manner
that the placard band 45 unrolls itself on the same. As this unrolling begins the
button e² of the placard band glides away from the isolated end of the contact
spring d, the latter falls down on the contact point 6, the wires 49 and 50° are
connected as conductors and the electro-magnet of the signal apparatus 51 is excited
whose call warns the passengers of the change taking place in the placard.
Meanwhile the peg m of the disc k has removed itself from the contact spring n so
that this can return to its position of rest and in doing so it breaks the current

page_text: which excited the electro-magnet p, the armature falls from the latter and the
friction wheel y moves out of contact with the friction wheel in consequence.
The latter remains accordingly at rest and stops in this way the motion of the
placard barrel onto which, during its revolution, the first placard of the placard
band wound on the barrel has unrolled itself. During this unrolling the second
button of the placard band 45 has glided under the isolated end of the
spring and the same breaks immediately the current which influences the signal
apparatus 51 and thus silences the latter. When the car approaches the store to
which the next advertisement refers, the disc has gradually turned itself
until the second of the pegs m of the same comes under the contact spring n, thus
again closing the circuit and repeating the operation just described. When the car
reaches its last station, the placards are all unrolled from the barrel onto the
barrel. At the beginning of the return journey, the placards have to appear in
the car in the reverse order corresponding to the reversed sequence of the places of
business. This is accomplished by a shifting of the parts by the cranked handle y
and the eccentric 1. By means of this handle the eccentric is caused to operate
the bevel gear wheels e¹¹ to cause the bevel gear el to become disengaged from the
bevel gear and at the same time cause the bevel gear to engage the bevel
gear ', and also, through the rod q' and bell crank lever p' drawing on the rod
and arm s moves the cog wheel h out of gear and thus reversing the direction of
movement of the connected parts.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
