' 3Claims. (Cl. 177-353) The present invention relates to improvements every element of a signal according to the Morse in an automatic telegraph receiving system code, and also to rotate the rollers 4 at a certain claimed in my United States patent application selecting line to a predetermined side according Serial No. 2,156, ?led January 17, 1935, and refers to the kind of each element.

Referring to Figs. 1 to 3 a rotatable controller formed by mounting a group of slidable contact making rollers 4 upon studs 3 arranged between opposite side plates 2 with equal space between each stud and an adjacent one to form a squirrel 55 cage, is adapted to rotate one'section forward for of a row of the studs 3. s and m are the levers partially ?tted to the ends of the rods 11.1 and uz connected to the armatures h' and g’ of magnets h and g respectively, so as to remove the roller 4 to correspond with a "letter space” and “dash” marks according to Morse code. They are pro vided at their ends- with pawls s’ and m’ con sisting of springs. k and l are push rods having the end pawls mesh with theteeth of the ratchets w and w’ ?xed to the shaft 8 of the rotatable body 2, while their other ends 01 and v2 are?tted to levers or rods Ill and Ill’ pivoted at their ends is and f4 respectively, said rods l0 and I0’ being ?tted to the ends of the rods us and 144 connected with the armatures i' and 1' of the electric mag nets i and 7'. Since it is undesirable to have the two select-‘ ing levers operate upon a roller of the same sec 2. 2,126,846 tion, these levers are provided with side aper tures and are guided‘to move horizontally, as described more clearly in my co-pending patent 36, 26, and 21, the battery C1 and the lines 22, magnets; K1 is a switch to change an aerial line N in a radio for a wire telegraph line T; K: is a 23, and 36; the magnet B closes the contact 0:.

' In Figure 6. A, B, D, E, h, 17,71, 7' show electric 10 an auxiliary contact 0 which opens when the switch is closed and which closes when the switch opens; R, a receiving relay; M, an ampli?er and amplitude regulator; C1 and C2 are’ electric 16 the line 34, the coil of the magnet B, the lines sources; F1 to F5 illustrate diagrammatically the arrangement of several series of multiple con tacts on the ?xed frame I; m to qt- are relays which are provided with normally open and in Consequently, upon receipt of the ‘dash’ mark by 10 this system, the magnets A, a’, B and g are actu ated to move the controller 2 forward by one step and at the same time to shift the roller 4 to the left from the middle position and thus transfer it to the ‘dash’ track. ' 15 Next,'in case of the letter space or the termi nation of an incoming signal, the contact 2| of the relay R is kept open for a longer time than stantly closed contacts 114 to m, normally closed and instantly open contacts 151 to is and holding the ‘space’ time and, accordingly, the contact ca .20 contacts e1 to es; L1 to L5 are signalling lamps; ' of the magnet A too is kept in a contacting con 20 Z and Z1 are buzzers. The relay A is provided with an electric con dition for a similar time. Therefore, on this oc casion D is energized by a circuit consisting of tact 01, which is a normally open and instantly closed contact, a normally open time delay clos 25 ing contact oz, and a normally closed and instant-‘ the closed contact 06, the lines 31 and 38, the coil of the magnet D, theJlines 39, 26 and 21, the battery C1 and the lines 22 and 22’. The magnet 25 ly opening contact ce.' The electro-magnets B, D D closes thevcontact c4, whereupon the magnet E is energized by a circuit consisting of the con and E are provided with normally open and in stantly closed contacts 03, c4, and as, respectively, , tact 04, the line 4|, the coil of the magnet E, the while the electro-magnets i and a‘ have push rods 80 k and Z, which in cooperation with theratchets w and w’ ?xed to the shaft of the rotatable body 2 move the rotatable body 2 forward by one step each time the magnets i and 7‘ are energized. As stated above, the electro-magnets h and 9‘ have 35 selective levers s and g, respectively, which shift the contact-making rollers 4 selectively when each magnet is operated, the lever 3 being pro vided with electric contacts a and b, which are closed when it operates. 40 ' In the arrangement shown in Figure 6, if the switch K1 is closed on the side of the antenna II or the wire telegraph line | 2 and the switch k: is kept closed and an electric signal correspond ing to the ‘dot’ mark is received, the relay R is energized so that it attracts its armature 20 and closes the contact 2|. Then the circuit of the lines 42, 26 and 21, the battery 01, the lines 22 and 22', the contact cc and the lines 31 and 31’. 30 The magnet E closes the contact 05, and then the magnet 11. is actuated by a circuit consisting of said closed’ contact 05, [the line 43, the coil of the ‘magnet h, the lines 46, 26 and 21, the batteries C1 and C2 and the lines 28, 29 and 45, thus remov 35 ing the roller'4 to the space track or the right track and at the same time closing the contacts a and b. Then, the magnet i is actuated by a circuit con sisting of the closed contact a, the line 46, the coil of the magnet i, the lines 46’, 29 and 28, the 40 batteries C2 and C1 and the lines 21, 26 and 41, and moves the controller 2 forward by one step through the ratchet W. ' - , In short, according to this arrangement, if the ‘dot’ mark is received, the controller 2 is moved 45 forward and the roller is caused to enter the electromagnet A is completed, said circuit com middle track. Also, in case of the ‘dash’ mark prising Cl, the lines 22, 23, and 23', the coil of the controller 2 is moved forward by one step, and the electro-magnet A, the line 24, the closed after that the roller 4 is caused to enter the left 60 contact 2|, and the lines 26, 26, and 21; then the track or ‘dash track’, while when it is a letter 50 electro-magnet A is operated. space, theroller is removed with regard to the If, however, the incoming signal is a ‘clotI mark, right track or the ‘space’ track, after which the the current flows through the coil of the magnet - controller is moved a step forward.~ The multiple contact groups F1—F5 shown. in A for a very short .time only, and, therefore, 60 merely closes and opens the contacts 01 and 0e, re Figure 6 have their respective contacts I4’, |5’,and 55 spectively, without closing the time delay con tact ca.‘ Then the circuit of the electro-magnet :i is completed, said circuit including the battery l6’ (see Fig. 3) arranged on the fixed frame-so as to be able to receive the signals “SOS”, the ordi nary call signal, “ABC”, the weather signal, C1, the line 22, the battery C2, the lines 28, 29, “MM”, the general search signal, “QC”, and the and‘ 36, the closed contact oi, the line 3|, the coil of the electro-magnet 1, and the lines 32, 26, and 21. Thus the electro-magnet 7' moves the controller 2 forward by one step through the alarm to sailing vessels, “TI‘T”, as indicated in 60 Figure 5. Consequently, with a single apparatus it is possible to receive several kinds of prede termined signals. Each of these contacts con sists of a stationary contact member I6 and a movable contact member having an arm l5 adapt ed to receive pressure from the roller 5; the con tact terminals l3 connected with these contact ratchet w’ by means of a push rod 1. However, upon receiving an electric signal cor responding to the ‘dash’ mark, the relay R at tracts its armature 20 to close the contact 2| for a comparatively long time, and consequently the electro-magnet A ?rst closes the contact 01 70 by the completion of an electric circuit similar to the one described and actuates the electro magnet 5!, whereby the controller 2 is moved for-' ward by one step, and then the time delay con tact ca is closed, so that the magnet B is ener 75 sized by a circuit consisting of 'the contact c2, members ‘ are connected in series in a certain order to correspond to the predetermined signals “SOS” and “ABC”, so that upon the entry of the 70 roller 4 into the ‘dash’ track, each ‘dash’ contact | I’ in said track is closed successively, while when it enters the ‘dot’ track, each contact H5’ is closed. Also, when the roller has been selected to the ‘space’ track, each contact I6’ is closed. 75 2,126,848 To explain this system, taking as an example the case where the distress signal "508” is re ceived, the time before the arrival of. the signal being equivalent to’the long letter space, the elec CI tromagnets h and z‘ are actuated to remove the roller No. 1 to the right track, as explained above with reference to Figure 6, and at the same time to move the controller 2 a step forward. Now, upon arrival of the signal "508”, viz. 10 u n 1 - 3 the switch K1, the line 4, the relay R, the line 58, the contact ts, the line 61, the contact t4, the line 68, the contact ta, the line 69, the contact t2, the line 10, the contact t1, the lines 1| and 12, the switch K1, and the line 13 to earth. Accordingly, 5 upon receipt of a desired predetermined signal any of the relays q1——qs operate to energize the corre sponding lamp and buzzer and at the same time the coil circuit of the relay R is broken by oneof the contacts t1—,te of any of. the operated relays a (Ii-(15, so that none but the ?rst arrived prede the controller moves forward three times for the ?rst three ‘dots’ and delivers the rollers Nos. 2, 3 and 4 to the middle track, and for the next letter " space transfers the roller No. 5 to the space track. With regard to the next three ‘dash’ marks repre termined signal is received. In the above example,although the alarm circuit completed up‘oh' receiving, for instance, the signal “SOS” is cut oil by opening the switch &, the 15 series contact in F1 regains its original condition corresponding to "808” when the switch K2 is at the same time transfers the rollers Nos. 6, 7 closed again, thus completing the alarm circuit. and 8 to the ‘dash’ track, while for the letter space To obviate this inconvenience, the switch K3 is 20 it removes the roller No. 9 to the space track. provided with the auxiliary contact 0, which is 20 Next, the rollers Nos. 10, 11 and 12 are sent to the temporarily closed when the switch K3 is opened, middle track successively for the three ‘dot’ marks and the magnet A is temporarily energized by a representing “S”, followed by the long letter space, circuit consisting of a contact 0, the lines 15 and when the electro-magnets h and i operate.‘ 24, the coil of the magnet A, the lines 23 and 22, Therefore, the controlled roller arrangement the battery C1, and the lines 21, 26, 25 and 16 to 25 takes the form shown in Figure 4. Accordingly, close the contact c1, whereby the magnet :i is actu the contacts of the contact group F1 are con- . ated to move the controller 2 forward by one step, nected in series and also since the electro-magnet thus breaking the connection of the series contact h is actuated to close the contact b in Fig. 6, the of F1, so‘that the alarm circuit is not completed alarm relay Qi is operated by a complete circuit again even if the switch K3 is closed again, and 30 the whole system is reset so that it is able to re consisting of the contact I), the line 48, the con ' tacts connected in series in the group F1, the line ceive the next signal.

That on this occasion the relay qi operates alone is evident from the dif ference of the arrangement of the contacts of. the groups F2—-F5 from that of the controlled rollers 40 Nos. 1-12 corresponding to “SOS”. Thus, as explained above, when “SOS” is re ceived and the relay m is operated, its holding cir cuit is completed by aKcircuit consisting cf the auxiliary contact e1, the lines 54 and 49, the relay m, the lines 5|’ and 5|, the switch K3, the lines 23 and 22, the battery C1, and the lines 21, 25, 55 and 56.
