associated there with and hereinbefore described the interrupted electrical signals received by the relay magnet 19 are converted or translated into continuous signals, that 1770is, continuous dots and dashes in the circuit of the relay 34. As each such continuous dot or dash is received the relay magnet 34 is energized a period of time corresponding to the whole length of such dot or dash, and 1775closes the main circuit of the second translating mechanism at the points, 35 and 37. Each time that an electrical signal is thus received the main analytic magnet 63 is energized and also the main synthetic magnet 1780106. If the signal received is a dot the selector 53 moves into engagement with the feed-screw 42 and the switch-arm 57 is moved a short distance on the insulation but does not engage any of the contacts 86, 87 1785and 88. The main synthetic magnet does, however, release the crow-wheel 107 from the locking finger 105 and permits the selector 118 to escape and strike the first dot pin, representing the letter “E”. When the 1790magnet 106 is energized its armature-lever 110 also closes at 265 and 266 one break in the circuit is open at the contacts 57 and 86, no current flows in the dash circuit. 1795When the circuit is broken at 35 and 37 the selectors of the analytic mechanism assume the positions shown in Fig. 14 but the switch-arm 58 does not travel far enough to engage any of the contacts 80, 90 or 91. 1800When the circuit is thus broken at 35 and 37 the escapement mechanism before described shifts the main selector 118 one step into the path of the second row of pins in the drum 143, and the contacts 265 and 266 1805are opened, as are also the contacts 115 and 116. The circuits of the main synthetic and main analytic magnets are through a source of energy, such as 273, and suitable switches such as the single-pole switch 274—which is 1810a ground-switch for cutting out all the electrically operated elements of the 1815second translating mechanism except the motor 26—and a double-pole switch 275 for cutting out the motor and all other elements of the second translating mechanism. The circuit through this double-pole switch preferably contains a pair of fuses, such as 276 and 277, and also a resistance 278. When a dash signal is received, the switch-arm 57 moves 1820to contact 86 and closes the main break to the dash magnet 162, the other break in said circuit having been closed at the moment of reception of the signal, as previously described, at 265 and 266, by the main 1825synthetic magnet 106. This circuit is as follows—from the switch-arm 57 to ground, to single-pole switch 274, conductor 279, double-pole switch 275, fuse 276, battery 278, fuse 277, resistance 278, conductor 280, to 1830the other contacts of the double-pole switch 275, conductor 281, main return conductor 282, conductor 283, contacts 265 and 266, conductor 284, dash magnet 162, conductor 285, contacts 185 and 186, conductor 286, and contact 86, the contacts both of the 1835single-pole and double-pole switches being closed, of course, when the machine is in operation, in order that the motor 26 may impart the necessary movements to the various parts of the second translating 1840mechanism. The motor 26, will be energized through conductors 287, 288 and 289, these conductors serving to connect the motor in a parallel branch of the circuit just described. When the magnet 162 is 1845energized it operates the lever 155, shifts the drum, as before described, in the direction of feed, and the lever 172 closes contact with the contact-arm 268 and thereby closes a shunt to ground instead of through conductor1850 286, thus maintaining the circuit of the dash magnet closed. At the same time that the lever 172 closes this shunt circuit at 268 the contacts 187 and 188 are opened by the lever 183, thus preventing the closure of the1855 circuit through the space magnet 164 during the reception of the code character after such dash occurs. If the signal element received is a longer dash than the ordinary one, to wit, the dash representing1860 the letter “L” in Morse code, the contact-arm 57 will travel as far as, and engage, the contact 87, and a circuit will be closed from the contact 87 and the contact-arm 57 through ground to single-pole switch 274,1865 and will follow the course hereinbefore described to the return conductor 282, from which the circuit will be by way of conductor 292, magnet 154 and conductor 298. This action results in the withdrawal of1870 the shiftable pin 1412 in the manner hereinbefore described. If the longest dash signal in the Morse code is received the contact-arm 57 moves as far as the contact 88 and closes a circuit through the ground and1875 through the connections before described to the conductor 282, from which the circuit is by way of conductor 290 to the magnet 153 and through conductor 291. When any dash signal is completed and the circuit broken1880 the magnet 106 is deënergized and contact is broken at 265 and 266, thus restoring the lever 155 and the parts coöperative therewith. the exception of the lever 183 and the contacts 187 and 188, to their normal1885 positions, and also restoring the drum 143. If an extra space is received, the arm 58 moves far enough to engage the first contact 89 of the other set of contacts, and thereby closes a circuit through 89 and 581890 and through ground to the devices herinbefore described in circuit with the battery 273, the circuit from the conductor 281 being through conductor 289 and conductor 294 to the contacts 255 below the 1895printing-
