Specification of Letters Patent.

Application filed July 8, 1912. Serial No. 708,283.

To all whom it may concem:

Be it known that I, ALIHONS RAPPE- NnoKnn, engineer, a subject of the German Emperor, residing at 102 Donanst-rasse, Bremen, Germany, have invented certain new and useful Improvements in Developing Apparatus for TWriting-Telegraphs and the Like; and I do hereby declare the following t-o'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an electrically driven developing apparatus for films,

chiefly for those writing-telegraphs which effect the transmission of communications by an clecho-photographic process. The apparatus, however, can be used also for any other development apparatus. The working of the receiving apparatus of the first mentioned writingtelcgraphs hitherto has not been con'lplctcly automatic, as the receivers always had to he attended by some one who cut oil, at a suitable point the posed portion of the film which was to be developed, from the remaining stock of film. This was a drawback, for the receiving ap paratus must be able to take text and pictures received and finish them photographically, even when nobody is present. To that end the device for cutting oil' the film is provided, according to this invmtion, with a gear which can be switched iii or out from the transmitting station; the gear in question being preferably conne ted to the feed device for the film and of he construction hereinafter described. Figure 1 shows diagrammatically the side elevation of the photographing and developing apparatus. Fig. 2 shows separately and on an enlarged scale. the automatic shears used for cutting the film. Fig. 3 shows the corresponding connection diagram.

The upper portion of the camera a is occupied by the drum Z) with the film 0, while in the bottom portion of the camera are arranged baths for developing and the like. The film 0 passes from the drum 1) first over the guide roller (1. thence bctwecn 'the guide rollers c and c. in order to pass-=1 er the guide roller 7 where it turns and passes around the dipping roller 9 0t theceveloping bath to the guide roller 71, dipping rollers of the fixing bath and between the guide rollers 7c, is out of the casing. On the rollers situated in the interior of the casing are mounted toothed wheels of about the same diameter arranged outside and marked with the same reference letters. The driving of the device is preferably efiected from the electric motor Z which, by means of the spindle m, rotates the Worm Wheel a connected by the toothed Wheel 9 to the toothed Wheels f andh. On the same spindle asthe toothed wheel 9, is mounted a smaller toothed wheel 0 for driving the spindle of the cam disk 9 on which is also mounted the toothed wheel 1;. The various rates of transmission and speed of rotation are calculated in such a manner that the cam disk 1 makes exactly one revolution during the complete operation of the device.

To the casing of the camera a is secured by means of bolts 1", the lever s which slides by me-ans of a block t, on the cam disk 1 and is pressed against the latter by springs. The free end of the lover s is connected, preferably through a spring, to a slide u on which is mounted. free to rotate on a pin, the coupling wheel '0 which, on the slide be ing raised, couples the wheels f and e. The slide 'u-is adjustable in a guide of the casing a which can be closed so that/no light can get in, and is controlled by a spring 10 which pulls it down (Fig. 2). The slide it engages by means of an eye m a pin of the blade 2 of the shears. this blade being pivoted about a pin 2. The other blade 3 of the said shears is arranged in a fixed manner above the film. A spring to engaging with the pivoted blade y, tends to close the shears.

.The working of the apparatus is as follows: As soon as the motor Z has received current from the telegraphic transmitter apparatus, it starts with the spindle m the worm wheel 72. the toothed wheel 0 and the cam disk q (first a little idle movement). The worm wheel 11. drives also the toothed Wheels f 7!- and also and 71;, it but at first without any action, as the film c and the rollers c, holding the same, remain unaffected. The coupling wheel 1) ot the slide a is, at the moment, still at such a distance from the wheels 7 and c that the teeth are not yet in engagement. Only when the lover s is slowly raised by the cam disk acting on the block 6 the slide a will also be raised and bring the coupling wheel o into engagement with the wheels 7' and 6. At that "moment the roller 9 will pull the 1 film and move it downward, so that as into an almost vertical means cotipe much film as required by the telegram taken,

will be carried under the fixed shearing.

blade 1 to the baths, in the meantime, the cam disk 3 has made almost a complete revolution, the lever s has been raised still further, and turned the pivoted blade ;1 oi the shears, which was previously horizontal, position. At the moment when the block 25 springs away from the cam at the cam disk 1 the slide a springs back into the initial position into which it is pulled by the spring to (Fig. 2), the loose blade y of the shears springing then into the closed-position of the shears and cutting the film On the cam disk q is mounted an electric contact device which, shortly before the end of the operative movement, breaks the circuit of the motor Z, so that the gear stands still. The small additional. movement of the motor (due to momentum) can be utilized for closing the contact again at the cam Wheel 9. At that moment, owing to special devices, the motor does not at once get current again, but remains standing still, until. it again receives current from the transmitter station, which takes place only when a new section of film is ready for developing and cutting oil. This is effected as follows: When at the transmitter station (Fig. 3), by a suitable operation of the writing pencil, orby any other means the contact 5 is closed within the line circuit 6 supplied with current by the source 7, the .relay 3 of the receiver station will attract the armatures 2 and thusclose the circuit of the source of current 4 of the receiver station, which will there upon drive the motor Z. The motor starts the gear of the lilm and its cut-tinged device, so that thecam disk Q rotates. The spring contact Z is normally closed and not atiected by the camdisk 9. Shortly before the end of its one revolution, the like of the cam disk strikes a spring projection of the contact Z, and opens it for a moment, so that the relay 3 releases the armaturcs 2 and breaks the motor circuit. The motor continues, however, to rotate a little, so that the cam disk completes its revolution, and the contact Z, being released by the stop pin, is again close l. The motor Z remains nevertheless without current. as the arnnitures 2 are lying free, and the line circuit is at rest. Obviously instead of the electric motor Z a clockwork driving device could be employed released from the trans mitter station. i
