PROVISIONAL SPECIFICATION.
Improvements in Signalling with Colored Lights.
I, CARL FRANZ EMANUEL BERG, Engineer in Chief of the Firm of Keiser & Schmidt
of 20 Tohannesstr: Berlin, Germany, do hereby declare the nature of this invention to
be as follows:
My invention relates to improvements in signalling with colored lights generated
by lanterns, the essential parts of which are represented by Fig. 1 in elevation by
Fig. 2 partially in plan. Two colored glass cylinders S G and S R are fastened
respectively to the racks Z and Z, which are coupled by the wheel R. The double
rack Z is in depth with the wheel R,, this carries the pinion T which works in R₁.
R₁ is one arm of a bend lever, having its fulcrum at H of which the other arm
terminates in the armature A.
After
When a current flows through one of the bobbins R, G or W the armature A is
attracted and hereby sets the wheels in motion, which causes the glass cylinders S G
or S R to ascend or descend or to place themselves in equal bight above the light L.
Three of such positions of the cylinders are represented in Fig. 4 by a, b, c.
attaining one of these positions the armature A. Fig. 1. is arrested either by V or V₁
or V and V, together and only the magnetisation of the bobbin, which sets the
required cylinder into the zone of the light L when a new signal is given, releases
the armature. The electric action of the bobbin on the armature is regulated by the
springs F and F..
With three lanterns as above described suspended one above the other 27 signals
may be given, as shewn in Fig. 7 and which may be conveniently employed for
indicating 16 points of the mariners compass Fig. 8.
Fig. shows the electric connection of the bobbins W, R, G of the three lanterns
suspended one above the other, and the signal switched is the 27th of Fig. 7 or South
of Fig. 8. The positions of their cylinders with respect to the light L are represented
in Fig. 4 by a, b, c.

I CARL FRANZ EMANUEL BERG, Engineer of Berlin W. Germany Schöneberger
Ufer 17 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:-
My invention relates to an Improvement in signalling with colored lights generated
by three constantly shining lanterns, suspended one above the other; lightened either
by electric or oil-lamps or candles, the light of which may be changed into white,
green or red according to the signal to be given. As in this system three lights
always compose one signal, no wrong reading can take place, if one of the lights is
shaded or extinguished by accident.
The lantern constructed for this purpose consists of a skeleton of three circular
plates P, P₁ P, each carrying three position rollers and P₁ in addition to C's a
pinion R.
To glass cylinders one green C G the other red CR glide with their bars B freely
along the position rollers C but are prevented from doing so by the pinion R and the
racks Z and Z.-The wheel R, carries a pinion P which is in depth with R₁. R₁ is one

page_text: end of a lever having its fulcrum at H terminating at its other end in the armature A.
Two clutches V and V₁ keep the lever arrested in three positions.
If the lantern has to shine with a red light the electric current, generated in I
Fig. 4, flows through the bobbin R. Before the armature A is allowed to move
towards R the bobbin has first to attract the clutch V, thus frees the direction towards R.
The armature A after reaching R becomes arrested by V. This movement is trans-
nitted by R₁, R, Z, to R, which is made to rotate such that the cylinder CR is
lowered into the zone of the light. Fig. 4, a,-Has the same lantern to shine with a
green light the current is switched to the bobbin G. G attracts first V and hereafter
the armature A which moves now in the direction A-G and causes the rack Z₁ with
the green cylinder CG to descend, but Z with the red cylinder to ascend Fig. 4. c.
If the lantern has to shine with white light the current flows through the bobbin W.
The clutches V and V₁ as well as the armature A are attracted, which places itself
in the position shewn in Fig. 1 and Fig. 4, b and sets the two cylinders in equal
height above the light.
As the armature A would move with an increasing rate towards the pole of the
bobbin R or G respectively when under the action of the pole only, springs S are
riveted on to the lever such, as to resist the increasing attraction of the pole by being
pressed against its stud. The mechanical force thus stored up in the spring rotates
after liberation the armature A towards that bobbin by which the armature is to
be attracted. If three such lanterns are suspended one above the other 27 signals
may be given by the system, Fig. 2. Fig. 3 shows 16 signals indicating 16 points of
the compass for the purpose of signalling the ships course by night, of which all the
easterly courses shine with a combination of red and white and all the westerly of
green and white lights, again all the northerly signals have one colored and two
white and all the southerly have one white and two colored lights. For each lantern
there is a switch U, U₁, U, on the top of the case of the small hand driven dynamo I
and according to the signal to be given the switch is brought into contact with the
white, red or green field of the switch. The signal switched in Fig. 4 is the 27 of
Fig. 2 or in Fig. 3 represents the course South, namely red, white, green.
At the moment the armature A becomes arrested, contact is made for a branch
circuit which indicates at U or U₁ or U₂ the appearence of the new signal above.
Having now particulary 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 :-
:―
In the interior of a signal-lantern the application of two colored glass cylinders CR,
CG fastened to two racks Z and Z, respectively, in connection with an electro
mechanical arrangement, having for its principal parts three electromagnets R, U, G,
the clutches V and V, and the armature A, which is one end of a lever having its
fulcrum at H, and of which the other end is a part of a wheel R₁, this gears in the
pinion of the wheel R, such that each movement of the armature A caused by
the attraction of one of the electromagnets is transmitted upon the glass cylinders,
which are thus made to ascend or descend for the purpose as described before,
and that this attraction of the electromagnets becomes first assisted and then
resisted by the action of springs S.
