COMPLETE SPECIFICATION.
Signal for Railway Guards to Open the Carriage Doors.
We, WILHELM VOGELER, Gentleman, of Cologne in the Province of Rhineland,
and JULIUS SEITZ, Cooper-master, of Bockenheim near Frankfurt-on-the-Maine,.
in the Province of Hessen-Nassau, Kingdom of Prussia, 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 apparatus hereafter described, and represented in the annexed drawing, is.
intended for the use of railway travellers so that when the train runs into the
station, where they intend to get out, they may give the guard a signal to open the
carriage doors.
2.
The apparatus, which in the accompanying drawing is represented in a vertical
section in Fig. 1, in a horizontal section in Fig. 2 and in a front view in Fig. 3, the
plate which covers the inner mechanism being omitted, is fitted up in twice each
compartment, being sunk into corresponding recesses in the sides of the carriage
close to the doors.
The apparatus consists of two parts, viz. the signal plate A with a suitable
inscription and the mechanism necessary for working it.
The signal plate A has a T-shaped section and consists of two plates t₁ and t
which are at right angles to each other, the former of which bears the inscription.
When not in use this plate remains in a corresponding slit S in the side of the
carriage, the slit S being completely covered over by plate t, in order to prevent
dust, rain, etc. from penetrating.
The signal plate A is provided at its lower end with a movable axis s... This
axis is fastened in the sides of a little box a, the cover of which contains a slit for
the reception of the signal plate when not in use.
The axis is surrounded by two spiral springs ff, of which one is fastened to
the right and the other to the left of the plate. These springs press with the one
end against the cover of the box a, the other ends are either attached to the signal
plate at its lower end, or rest against small pins which are riveted to the plate, 80
that on the plate moving downwards the springs are bent, but on its moving
upwards they expand again.
The motion of the plate is effected by a pull-mechanism which enters through
the side of the carriage into the interior of the compartment and there terminates.
in a handle, knob or the like, which the passenger must pull in order to be able to
give the signal.
°
The pull-mechanism consists of the draw-rod b which is provided with a handle as
mentioned before and is guided in a socket c let into the side of the compartment
and having at its other end a second rod or little chain connected to it by a hook.
This rod or chain is firmly fastened to the lower end of the signal-plate T.
If a passenger who wishes to leave the compartment wants to call the attention
of the guard, it is only necessary for him to pull the knob. This causes the plate
to be moved out of the slit and to assume the position shown by dotted lines in
Fig. 1. This motion of the plate at the same time causes the spiral springs ffi to
be bent.
As soon as the guard has opened the carriage door, the passenger lets go the
handle, the bent springs immediately expand again and bring back the plate T
automatically into its original nosition in the slit

page_text: The apparatus may also be so arranged that on drawing the handle the plate
falls down, but does not of itself return to its position when the handle is let loose,
but must be put back personally by the guard when he opens the door.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim, is:
Signal apparatus for railway carriages consisting of a signal plate A provided
with an inscription and so arranged that it can fall outwards from a slit S in the
side of the carriage, and is made to fall outwards by a draw-lever mechanism and
to return of itself to its original position in the slit, on the lever being let go, by
the force of a spring, for the purpose of causing the guard to open the door.
Dated this First day of September 1894.
