Improvements in Railway Station Indicators.
I, TILLMANN WELFONDER, Workmastor of Bielofold in the Province of Westphalia
aud Kingdom of Prussia do hereby declare tho naturo of this invention to bo
as follows:-
The present invention relates to an apparatus which is to be fitted up in the
various compartments of railway travelling carriages and is intended to indicate to
the traveller the names of Hifforont stations as well as other notico roferring to them
before the train runs into tho station.
In the annexed drawing Fig. 1 ropresents the apparatus in a front view, Fig. 2
in a longitudinal view to x--x of Fig. 1, while Fig. 3 is a view of the mechanism
that actuates the apparatus.
The apparatus is fitted up in a case A attached to a suitablo part of the
compartment. a is a disc which is attached to a ratchet wheel c and on the surface
of which the namos of the consecutive stations of the liuo in question as well as
any notices referring to these stations e.g. change for ...; 5 minutes stop, etc.
aro arrauged in such a nauner in a circle that on the ratchet-wheel turning one
tooth a name of a station appears each time in a gap in the cover B of the case
(Fig. 1).
Close to the ratchot-wheel c is the pawl d, the teeth of which g12 alternately
engage with the gaps of the wheel and move it on each time the length of ono
tooth.
The motion of tho pawl is caused by a pull-mechanisin which is worked by the
guard. A spring f at the other end of the pawl after the train has stopped draws
back the tooth g1 of the pawl at whereupon the tooth g2 catches into the gap
of the ratchet-wheel in front of it and provents it from turning any further.
As will be seen from Fig. 1 the opening o in the cover of the case can be closed
by two slides 8, 8, of which 8, is hero pushed back while 8, covers the lower half of o.
This arrangemecut makes it possible also to indicate the stations on the return
journey on the same section. For this purpose a second ring is marked with the
names of the stations written in reversed order on the disk below the first ring.
After slide 8, has been closed and 8, opened and on the disc a being turned, these
names appear behind the lower part of the opening o. Since tho disc a is only
fastened with two screws b₁ be to the ratchet-wheel it can easily be replaced by
others. The apparatus can therefore be easily employed for different lines.
Inving now particularly described and ascertained the naturo of my said
invention, and in what manner the same is to be performed, I declare that whint
I claim is:
A Station-announcer for railway trains distinguished by the disc a enclosod in a
case with the names of the stations arranged in the shape of a ring on the upper

page_text: side together with notices referring to them, the disk boing connected in such a
manner with a click and ratchet-wheel that by the motion of the lever of the click
the disk is moved forward one tooth, the names of the stations being thus brought
one after the other behind an opening in the cover of the case.

I, TILMANN WELFONDEE, Workınaster of 69 Herforder Street, Bielefeld in the
Province of Westphalia and Kingdom of Prussia do hereby deolare 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 present invention relates to an apparatus which is to be fitted up in the
various compartments of railway travelling carriages and is intended to indicate to
the traveller the names of the different stations as well as other notices referring
to them before the train runs into the station.
In the drawing, filed with the Provisional Specification, Fig. 1 represents the
apparatus in a front view, Fig. 2 in a longitudinal view to - of Fig. 1, while
Fig. 3 is a view of the mechanism that actuates the apparatus.
The apparatus is fitted up in a case A attached to a suitable part of the
compartment. a is a disc which is attached to a ratchet-wheel c and on the surface
of which the names of the consecutive stations of the line in question as well as any
notices referring to these stations e.g. change for ; 5 minutes stop, and the
like are arranged in such a manner in a circle that on the ratchet-wheel turning one
tooth a name of a station appears each time in a gap in the cover B of the case
(Fig. 1).
Close to the ratchet-wheel o, is the pawl d the teeth of which g 1 g 2 alternately
engage with the gaps of the wheel and move it on each time the length of one
tooth.
The motion of the pawl is caused by a pull-mechanism t which is worked by the
guard. A spring fat the other end of the pawl after the train has stopped draws
back the tooth 1 of the pawl at t, whereupon the tooth g2 catches into the gap of
the ratchet wheel in front of it and prevents it from turning any further.
As will be seen from Fig. 1, the opening o in the cover of the case can be closed
by two slides 182, of which 8 1 is here pushed back while 8 2 covers the lower
half of o.
This arrangement makes it possible also to indicate the stations on the return
journey on the same section. For this purpose a second ring is marked with the
names of the stations in reversed order on the disk below the first ring. After
slide, 81 has been closed and 8 2 opened and on the disc a being turned, these names
appear behind the lower part of the opening o. Since the disc a is only fastened
with two screws b162 to the ratchet-wheel, it can easily be replaced by others.
The apparatus can therefore be easily employed for different lines.
Having now particularly described and ascertained the nature of my said 4
invention and in what manner the same is to be performed, I declare, that what
I claim, is:
A station-announcer for railway trains distinguished by the disc a enclosed
in a case with the names of the stations arranged in the shape of a ring

page_text: upper side together with notices referring to them, the disc being connected in
such a manner with a click and ratchet-wheel that by the motion of the lover of
the click the disk is moved forward one tooth, the names of the stations being thus
brought one after the other behind an opening in the cover of the case.
Dated this 20th day of August 1897.
