FRIEDRICH HERMANN FELIX ENGEL Civil Engineer and Patent Agent of
Hamburg Gerinany "IMPROVED APPARATUS FOR EXHIBITING ADVERTISEMENTS
AND PLACARDS ON TRAM-CARS OMNIBUSES AND OTHER WHEELED VEIIICLES
A communication by Gustav Richter Engineer of Altona in the German Empire.
"
This invention relates to improved apparatus for exhibiting advertisements and
placards on tram cars omnibuses and other wheeled vehicles and has for its object
to construct revolving discs or rings on top of tram cars, omnibuses or other
wheeled vehicles said disc or rings being operated by transmission from the axles
or wheels of such vehicles which rings or discs may be used for attaching or for
moving advertisements and placards of any kind.
The construction of this apparatus is as follows: on top of the vehicle is
fastened a piu or stud supporting a tube which carries by means of studs a
metal ring. To the foot of the above tube a horizontal disc is fastened which is
by transmission of a rope or cord in connection with another horizontal disc
fulcrumed on top of the vehicle and fastened to the end of a shaft carried through
the vehicle and enclosed in a stationary tube. This shaft is by means of conical
wheels and a pulley or disc in gear with one of the axles or a boss of a wheel of
the carriage and is operated by such axle or wheel while the vehicle is in motion.
The ring or disc on top of the vehicle is consequently brought in revolving
motion whilst the vehicle is running and can be used for attaching placards or
advertisements to it which will revolve with it while the vehicle is in motion. Or
a second ring likewise support by means of a tube on another stationary pin or
stud fastened to the other end or other part of the top of the vehicle may by
means of an endless band or belt be connected with the ring driven by the motion
of the vehicle and advertisements or placards may be attached to such band or
belt in which case the advertisements or placards will revolve with the endless
band or belt along the top of the vehicle.

FRIEDRICH HERMANN FELIX ENGEL Civil Engineer and Patent Agent in the
City of Hamburg Germany "IMPROVED APPARATUS FOR EXHIBITING ADVERTIZE-
MENTS AND PLACARDS ON TRAM CARS OMNIBUSES AND OTHER WHEELED VEHICLES
A communication by Gustav Richter Engineer of Altona in the German Empire.

This Invention relates to improved apparatus for exhibiting advertizements and
placards on Tramcars, omnibuses and other wheeled vehicles and has for its object
to construct revolving discs or rings on top of Tramcars omnibuses or other
wheeled vehicles said discs or rings being operated by transmission from the
axles or wheels of such vehicles which rings or discs may be used for attaching
or for moving advertisements and placards of any kind.
The construction of tliis apparatus-is-as-follows-on_top_of the vehicle is
fastened a pin or stud supporting a tubo which carries by means of struts a metal
ring To the foot of the above tube a horizontal disc is fastened which is by
transmission of a rope or cord in connection with another horizontal disc fulcrumed
on top of the vehicle and fastened to the end of a shaft carried through the vehicle
-and enclosed in a stationary tube-This shaft is by means of conical wheels and a
pulley or disc in gear with one of the axles or a boss of a wheel of the carriage.
and is operated by such axle or wheel which the vehicle is in motion.
The ring or disc on top of the vehicle is consequently brought in revolving
motion whilst the vehicle-is-running-and-can-be used_for_attaching placards or
advertisements to it which will revolve with it while the vehicle is in motion-
Or a second ring likewise supported by means of a tube on another stationary pin
or stud fastened to the other end or other part of the top of the vehicle may by
means of an endless band or belt be connected with the ring driven by the
motion of the vehicle and advertisements or placards may be attached to such
band or belt in which case the advertisements or placards will revolve with the
endless band or belt along the top of the vehicle.
In order that the said Invention may be well understood reference is made by
figures and letters in the following particular description to the accompanying
sheet of drawings wherein Fig: 1 is a side elevation and Fig: 2 a cross section
of an Omnibus furnished with the apparatus
a, is a pin or stud fastened to the top of the carriage supporting a tube 6 that
carries a ring R to the outer circumference whereof the advertizements are
attached. By means of pullies m n, rope d vertical shaft p and conical gear o h,
the Ring R is rotated during the motion of the carriage, the shaft e carrying the
conical wheel h is driven by a rope, i and pullies 8, 8¹.
By placing a second ring, similar in size and construction to the former one on
top of the carriage, an endless band, can be put around both rings which revolves
as soon as ring R rotates by the motion of the vehicle-Such band may be used
for advertizing purposes in same manner as the single ring before described.
Having now described the nature and particulars of the said Invention
I claim:-
=
Firstly The combination of Ring supported by pin a on top of a vehicle and
driven by gearing and pullies from one of the wheels of the carriage during the
motion of the vehicle as and for the purpose herein described and

page_text: Secondly The combination of two rings R on top of a vehicle connected by
an endless band driven by gearing and pullies as and for the purpose herein
described.
In Witness whereof I the said Friedrich Hermann Felix Engel have hereunto
set my hand and seal this sixteenth day of October in the year of our Lord
One thousand eight hundred and eighty-two.
