Addendum to patent 210207 of December 4, 1907.

Patented in the German Empire on March 12, 1909. Longest duration: December 3, 1922.

Patent 210207 of Cl. 74 d deals with a device for emitting optical signals, which consists of a clock provided with a chronometer hand, and which is characterized in that the disc (or the dial) carrying the time division itself or an annular disc concentrically surrounding it can be rotated is arranged around the pointer shaft.
A special embodiment of the subject matter of patent 210207 relates to the device that, in conjunction with a continuously rotating chronometer hand, a manually adjustable pointer is arranged, whereby the repeated stopping and restarting of the chronometer hand, which is a source of error, is avoided.

The subject of the present invention are some to increase the usability Directed improvements, through which the legibility of the characters as well as the adjustment of the pointer described in the last mentioned particular embodiment facilitated and the number of characters is doubled each time this pointer is readjusted can be read.

As can be seen from the accompanying drawing, the device has the known chronometer device, in which a chronometer hand h can be stopped one after the other by moving a pusher m , returned to the graduation mark XII and set in motion again from this position.

This chronometer pointer h is designed with two arms in the present device and extends over the dial α surrounding the actual dial 0 , which can be given any rotation about the pointer axis by turning a button p.

For the purpose of making it easier to read, the rotatable drawing disk α is not turned on as before. their entire surface, but only on one half with the characters, so that the reading end only has to follow the moving pointer h on one half of a circle, which enables increased attention and prevents the observer from becoming tired.

The marked half of the disk a is divided into two concentric fields and these are again divided into ring sector-shaped fields by radial lines; Two letters are drawn in two diagonally opposite corners of each ring sector.

In addition to the constantly revolving pointer h , a pointer cross t is arranged, which is connected to the chronometer movement in a known manner in such a way that when the pusher m is moved it begins to rotate simultaneously with the chronometer pointer h, stops when the pusher η is moved and

If you move the same pusher again, it jumps after pointer h and continues with pointer h .

The method of use of the device is as follows:

According to the arrangement taking place in accordance with displacement of the movable disc mark a of the pointer from that of the clock corresponding ίο rest position at both stations set the graduation mark XII in motion simultaneously h together with the pointer Cross t; the pointer h remains in motion during the entire time of the character transmission.

When one of the arms of the pointer h comes to the borderline of the field which contains one or more characters to be telegraphed, the pusher η is moved so that the pointer cross t separates from the pointer h and remains at the point where it is at the time the movement of the pusher η .

Four characters fields by the two characters on the disc lying a cross arms of the pointer t thus marked, and if, for each character field. B. if there are two characters, the position assumed by the pointer cross indicates eight characters.

Those of these eight signs that are to be signaled are usually triggered by movement or position of one or two signal flags; should be the ones from the pointer cross covered fields have two or more consecutive letters, so these are signaled in the order corresponding to their letter position in the word.

After signaling the letter or letters in question, the pusher η is moved, as a result of which the pointer cross t jumps after the pointer h and continues to rotate with it.

The improvement described achieves the following advantages:

The fact that the character disk a is only covered on one half with characters makes it easier to observe the movement of the pointer and to read the characters, and as a result, the observer's eye is less tiring.

By means of the fact that the stationary pointer cross t can be brought into line with the constantly rotating pointer h by moving a pusher η and does not have to be readjusted by hand, the delivery of the telegram is accelerated and the observer's attention is distracted from the signaling station avoided.

Finally, by using the cross-shaped jump pointer t, twice the number of fields is covered each time the pointer is jumped, thereby increasing the probability that two or more characters can be signaled every time the cursor jumps.

Claims (2)

65 patent claims: 1. Device for emitting optical signals, consisting of one with a chronometer pointer equipped clock, on whose disc (or dial) bearing the time division, apart from the hour division, signal signs are applied in concentric circles according to patent 210207, characterized in that that the adjustable disc carrying the characters to be signaled is provided with characters only on one of its halves is. 2. In connection with the device according to claim 1, the arrangement of a jump pointer, characterized in that it has the shape of a pointer cross ft) , for the purpose of falling in each position two arms of the pointer cross on the half of the disc covered with characters permit. 1 sheet of drawings.
