Improvements in and connected with Station-indicators.
FERDINAND ZIPPERLING 18 Katzlerstrasse, Berlin, Kingdom of Prussia
Empire of Germany, Cooper 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 present invention relates to an apparatus which enables to show in travelling
railway trains the names of the stations in either direction; without the mechanism
having to be interfered with from outside.
In the accompanying drawing
Fig. 1 is the front-view of the mechanism the head-wall of it being removed.
Fig. 2 is the longitudinal view, with the side-wall taken off.
Fig. 3 shows the click-mechanism in its state of repose;
Fig. 5 is a section II of the click-mechanism in Fig. 3, and Fig. 4 shows it
when worked.
For
Two equally running rollers A. A₁ are carrying a strip B of paper, linen, raw
silk or the like, which passes from one roller to the other and has printel on it the
names of the stations, advertisements, or other indications. These rollers A A₁
which, in order to work uniformly, are connected with each other by toothed or
chain-wheels with chain (rr, k), are moved by electro-magnets E E₁, one for each
direction of turning. The electro-magnets E E, are attracting the armatures a a₁
which latter (a a₁) are each turning forward a click-wheel ss1₁ each by one tooth
and each by ineans of a double-lever H H, on the other end of each of which a
click-hook, is attached. Now as the click-wheels must have teeth suitable for
forward and backward motion the two detents h₁ must check each other.
this purpose both parts are so connected by rods, that the active lever every time
disengages the detent of the inactive lever. In Fig. 1 the electro-magnet E₁ is
active. At the lever H, is the rod u, which is guided in a slit n of the double
lever m, turning loosely on the shaft of the click-wheel s. When the electro-
magnet E attracts the armature a,, the rod u goes upwards and glides ineffective
into the slit of the lever-end. The detent h lies with its pin in a hollow of the
lever-end m and is thus free from the click-wheels; this enables the click-wheel S
to turn backward. The apparatus thus works through the electro-maguet E₁.
If the train is returning on the same line the electro-magnet E is excited; the
same attracts the armature a and draws the rod o upwards; as the latter now stands
at the upper end of the slit n₁ of the lever m₁, it draws this lever-end from m₁
upwards, the other lever-end goes down and glides along the pin x₁ of the detent /₁
thereby pressing the latter off from click-wheel until places itself into the
groove of the lever and this fixes itself; in releasing the arinature a and lowering
the rod o its lower end again glides ineffective into the slit n₁ downward and thus
the detent h, is disengaged. By lifting the lever-end H the upper detent is also.
lifted and with it lever m moves upward, until the detenth leans against the wheel s
and the pin ceases to hold the lever m by the weight of the detent, then the
heavier side of the lever m acts which lies by the slit n and lever m takes a straight
position, similar for example as lever m₁ lies in Fig. 1, where the pivot cannot
touch the lever m and place itself into the groove. Figs. 3, 4 and 5 show a brake
as it must be engaged in the sudden effect taken by the electro-magnet in order to
stop the living power of the rotated bodies. For this purpose the click-wheel (1) is
10

page_text: provided with pins c, according to the number of teeth. At the oscillating lever H,
is a plate b₁ bent in the circumference round d₁ with a notch b, through which the
pins c₁ can pass. When in moving the click-wheel s, by the click-lever h₁ a pin b₁
has passed through the notch b₂, the full part of plate b, enters into the circle of С1
and the next pin can only get as far as the plate. Thus the wheel s₁ can never be
turned more than by one tooth. A second safety against unintentional turning
which may be caused by the shocks of the carriage, is effected by the tooth z₁
provided at the detent, which places itself before one of the pius c₁ and thus
secures the click-wheel in connection with the detent h₁ against moving. The
levers HH, are always kept by a spring ffi so that the armatures a a₁ are
suspended over the electro-magnet E E₁.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. In a station- and business-indicator the exclusive jumping action, forward and
backward, of two drums (A A₁) carrying a ribbon (B) with the names &c. rolled
off or on by two electro-magnets independent of each other, each driving the click-
wheel belonging to it one tooth forward by its armature (a) in connection with a
lever and click, fixing and securing it, and at the same time disengaging the other
magnet in order to permit the forward-turning of the apparatus substantially as
described.
2. In the lever and click-apparatus indicated in the previous claim the
modification of the peculiarly shaped double levers (m m₁) provided with grooves
for receiving the pins (1) at the detents (h₁), and a longitudinal slit (nn) in
the other end for receiving the rods (o u) worked by the said levers (H H₁) for
moving the levers (m m₁) and thus effecting disengagement and fixing each one of
the detents, substantially as described.
3. In the lever and click-arrangement indicated in Claim 1 the modification of
a nose (2) arranged at the detent (h h₁), and a plate fixed at the lever (H H₁)
provided with a notch for letting pass the pins (c) arranged at the click-wheel (s s₁),
which, lifted up by the lever (HH,), holds fast the following pin after the previous
one has passed, substantially as described.
