Zusatz zum Patent 248332 vom 7. März 1911.Addendum to patent 248332 of March 7, 1911.

Patentiert im Deutschen Reiche vom 22. April 1911 ab. Längste Dauer: 6. März 1926.Patented in the German Empire on April 22, 1911. Longest duration: March 6, 1926.

Der Apparat nach dem Hauptpatent 248332 läßt nicht plötzlich und ganz die aufeinander folgenden Farben erkennen, sondern diese erscheinen allmählich und nur teilweise im Fenster z. Es ergibt sich daraus eine gewisse Schwierigkeit im Erkennen der Farben in der Entfernung. Diesem Mangel abzuhelfen, ist dem Apparat ein bewegliches Fenster beigefügt, damit nur eine Farbe sichtbar wird undThe device according to the main patent 248332 does not suddenly and completely recognize the successive colors, but these appear gradually and only partially in the window z. This results in a certain difficulty in recognizing the colors at a distance. To remedy this deficiency, a movable window is attached to the device so that only one color is visible and

die Farben bei Übergang in eine andere Geschwindigkeitsstufe sofort aufeinander folgen. Das bewegliche Fenster ist mit dem bereits beschriebenen Apparate folgendermaßen verbunden : .the colors when changing to another speed level immediately follow one another. The movable window is with that already described apparatus connected as follows:.

Jedem farbigen Felde I, II, III . . . der Scheibe q entspricht eine diametral gegenüber am inneren Umfange der Scheibe und in deren Ebene liegender Stift Γ, ΙΓ, ΙΙΓ. . . . Diese Stifte haben die gleiche Länge, weil die Farben gleich bereit sind. Das Fenster ζ besteht aus zwei Teilen, einem festen, in die Wand des Kastens eingeschnittenen und einem beweglichen Teile. Der feste Teil ist ebenso hoch wie ein farbiges Feld der Scheibe, jedoch dreimal breiter als ein solches. Der bewegliche Teil besteht wieder aus zwei Teilen, einer Scheibe s, die um eine an der vorderen Wand des Kastens angebrachte Achse O₂ in beiden Richtungen mit Hilfe zweier fest auf einer Achse O₄ sitzender Räder ^₄ und P₄' gedreht werden kann.Each colored field I, II, III. . . the disk q corresponds to a pin Γ, ΙΓ, ΙΙΓ diametrically opposite on the inner circumference of the disk and in its plane. . . . These pens are the same length because the colors are ready in the same way. The window ζ consists of two parts, a fixed part cut into the wall of the box and a moving part. The solid part is as high as a colored field of the disk, but three times wider than such a field. The moving part again consists of two parts, a disk s, which can be rotated _{in both directions about an axis O 2} attached to the front wall of the box with the aid of two wheels ^ ₄ and P ₄ _{'fixed on an axis O 4.}

Der erste Teil der Scheibe s besitzt ein am inneren Umfange teilweise gezahntes Rad r.₂'; das in das Rad r_i eingreifen kann. Der zweite Teil ist der Abschnitt eines Radkranzes von etwas größerer Höhe als Scheibe q. Der Mittelwinkel dieses Abschnittes ist fünfmal so groß als der eines farbigen Feldes. Dieser zweite Teil hat in der Mitte ein Fenster z₂ von der Größe eines farbigen Feldes, also sind die links und rechts des Fensters Z₂ liegenden Teile der Scheibe doppelt so groß wie das Fenster. Auf diesem zweiten Teil befindet sich ferner ein Stift S₃, der so angebracht ist, daß er sich immer zwischen den beiden Federn f₃ und /"₄ befindet. Diese Federn f_s und f₄ sind in ein und demselben Punkte der vorderen Kastenwand befestigt. Dieser Punkt kann in der Verlängerung von. O₂ liegen, jedenfalls auf einem Punkte der Symmetrieachse NS. The first part of the disk s has a wheel r which is partially toothed on the inner circumference. ₂ '; that can intervene in the wheel r _i. The second part is the section of a wheel rim slightly greater in height than disk q. The central angle of this section is five times that of a colored field. This second part has a window z ₂ in the middle the size of a colored field, so the parts of the pane lying to _{the left and right of window Z 2 are twice as large as the window.} On this second part there is also a pin S ₃ which is attached in such a way that it is always located between the two springs f ₃ and / " _4. These springs f _s and f ₄ are fastened at one and the same point on the front box wall This point can lie in the extension of .O ₂ , at least on a point on the axis of symmetry NS.

Die an der vorderen Wand des Kastens angebrachte Achse O₄ kann in beiden Richtungen angetrieben werden, einmal durch die Scheibe s mittels der Räder r₂' und r₄, andererseits durch die Stifte I', II', III' ... des Kranzes q mittels des Rades f₄'. Das Rad r₄ ist an seinem Umfange so gezahnt, daß es immer in den, gezahnten Teil r₂' der Scheibe s eingreift. Der Radius dieses Rades /₄ muß so gewählt werden, daß, wenn der Radius von r₂' der Scheibe s einen Rotationswinkel U)₃ macht, die Achse O₄ den _{The axle O 4} attached to the front wall of the box can be driven in both directions, on the one hand by the disc s by means of the wheels r ₂ ' and r ₄ , on the other hand by the pins I', II ', III' ... of the rim q by means of the wheel f ₄ '. The circumference of the wheel r ₄ is toothed in such a way that it always _{engages in the 'toothed part r 2} ' of the disk s. The radius of this wheel / ₄ must be chosen so that when the radius of r ₂ 'of the disk s makes an angle of rotation U) ₃ , the axis O ₄ den

Claims

Rotation angle ω ₂ makes. This is expressed by a formula:

Ui ₂ will be determined below, w ₃ is equal to the central angle of a colored field. The wheel r ₄ 'is not toothed, but has two

ίο pins S ₁ and S ₂ . These are _{equidistant from o 4} , so that when the axis o ₄ rotates, the two pins pass through _{the circle C 1} C _1. The pins S ₁ and s ₂ are so far apart that their corresponding central angle _{is equal to α · 2} , and their position on the circle C ₁ C ₁ must be such that when the pin S ₃ lies on the geometric axis NS , they are symmetrical about the axes. The geometric construction

ao of the angle ω. ₂ , whereby this angle u ' _{2 is} determined, is the following:

A line a O ₂ η is drawn through the center point o ₂ , which with the axis NS denotes

Angle - of half a colored field

2 ^b 2 ^b

corresponds, makes. This line intersects the circle C ₁ C ₁ 'at point n. Now we describe the circle c c' _{in o 2} with radius O ₂ η. This circle is then the geometric location for the free end points of the pins P, II ', IIP. ... the disk q, and the same circle intersects the circle C ₁ C ₁ 'at points m and n, the arc distance of which corresponds to the angle w _2.

This is how the angle is

and the length of the pins of the disk q is determined.

As already said in the description, this arrangement of the window has the purpose that only one color is visible at a time. The process is as follows: Assume that the motor vehicle is currently at the lowest speed of level III, and the corresponding color III lies in the angle «ο ₂ δ. In this position of the disk, pin III 'is in the extension of diameter α o ₂ n, namely the end of this pin at point n, while pin ΙΙΓ touches pin S ₂ , which is also at the same point at this point in time and pin s ₃ is at the same time on the axis NS . It follows that the window z. ₂ comes to lie in front of field III and makes it visible. If the speed now increases, then the disk q is rotated in direction 2, and the pin III 'will take the pin S ₂ with it and thus _{rotate the axis O 4} and the wheel r ₄ and the disk s in the same direction. The disks s and q are rotated by almost the same angle of rotation. At the same time, the pin s ₃ bends the spring f ₄ , but remains in contact with it. So the color III remains visible as long as the increase in speed still falls within the range shown by the visible color. But if the speed increases further, at the moment when speed III changes to IV, color IV will be at angle α o ₂ b and thus pen ΙΙΓ will move to m and lose contact with S _2; this contact has existed in the area of the dashed segment η m. At this moment the spring / " _{4 can} quickly bring the pin s ₃ back onto the axis NS , so that the window z ₂ comes in front of the color IV and this becomes visible The process takes place in the opposite sense when the speed decreases, only that in this case the pin S ₁ and the spring f _{3 become} effective.
