Definitions

  • the present invention is characterized by the fact that the sets of the groups of contact switching elements arranged to correspond with the arrangement of said controlled rollers are provided in a large number for several different signals, so that if there is any one among these sets which corresponds to an arriving signal, it is selected to complete its own alarming circuit; and also that directly after the operation of one set another signal is received and the corresponding set is operated in turn.
  • the object of this invention is to enable a single system to serve as several different receiving systems and to receive messages independently of one other.
  • the mechanical structure of the selector used in the present invention is described more clearly in my British Patent No. 436,343, or my French Patent No. 791,554, which correspond to the application previously mentioned.

  • Groups of switches to complete the contacts by being operated by the rollers are arranged to correspond with the expected signal and are connected to an alarming electric circuit, so that upon coincidence with an arriving signal they may be operated.
  • sets of several contact switching elements are pro- 'vided for many different signals and are connected to their respective alarming circuits equipped with electric magnets for operating electric lamps and other alarming devices said magnets having auxiliary contacts for self-holding in order that when-a set of contact point arrangement is operated by the arrival ofthe corresponding signal the alarming may be continued, unless said magnets are opened, and when another signal follows the above one, substantially the similar operation is caused.
  • I is a fixed frame of drum type secured to the base of the machine at either side of the rotatable body 2 and forms a bearing I for the shaft 8 of the rotatable body.
  • I holes 9 for attaching the contact switching elements are provided at the position corresponding to that of each stud 3 of the rotatable body 2.
  • 5 are several arcshaped partitions starting from a section next to the selecting line of the contact making rollers. They are combined with suitable holding plates 6 to partition the positions of the forward movement of the rollers into three tracks; 1. e., right, middle and left tracks, along the outer periphery of a row of the studs 3.
  • s and m are the levers pivoted to the base at pivots f1 and f2 and also partially fitted 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 provided at their endswith pawls s and m consisting of springs.
  • k and l are push rods having the end pawls mesh with theteeth of the ratchets w and w fixed to the shaft 8 of the rotatable body 2, while their other ends 01 and v2 arefitted to levers or rods Ill and Ill pivoted at their ends is and f4 respectively, said rods l0 and I0 being fitted to the ends of the rods us and 144 connected with the armatures i' and 1' of the electric magnets i and 7'.
  • A, B, D, E, h, 17,71, 7' show electric magnets;
  • K1 is a switch to change an aerial line N in a radio for a wire telegraph line T;

  • the electro-magnets B, D and E are provided with normally open and instantly closed contacts 03, c4, and as, respectively, while the electro-magnets i and a have push rods k and Z, which in cooperation with theratchets w and w fixed 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.
  • the electro-magnets h and 9 have selective levers s and g, respectively, which shift the contact-making rollers 4 selectively when each magnet is operated, the lever 3 being provided with electric contacts a and b, which are closed when it operates.
  • the current flows through the coil of the magnet A for a very short .time only, and, therefore, merely closes and opens the contacts 01 and 0e, respectively, without closing the time delay contact ca.
  • the circuit of the electro-magnet :i is completed, said circuit including the battery C1, the line 22, the battery C2, the lines 28, 29, and 36, the closed contact oi, the line 3
  • the electro-magnet 7' moves the controller 2 forward by one step through the ratchet w by means of a push rod 1.
  • the relay R attracts its armature 20 to close the contact 2
  • the magnet B closes the contact 0:.
  • the magnet Q is energized by a circuit consisting of the closed contact 03, the line 33, the magnet g, the lines 33', 26, and 21, the batteries C1 and C2, and the lines 28, 29, and 40, and moves the roller4 along the stud 3 by a selective lever m so as to transfer it to the dash mark track. Consequently, upon receipt of the dash mark by this system, the magnets A, a, B and g are actuated 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.
  • of the relay R is kept open for a longer time than the space time and, accordingly, the contact ca of the magnet A too is kept in a contacting condition for a similar time. Therefore, on this occasion D is energized by a circuit consisting of 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 controller 2 if the dot mark is received, the controller 2 is moved forward and the roller is caused to enter the middle track.
  • the controller 2 is moved forward by one step, and after that the roller 4 is caused to enter the left track or dash track, while when it is a letter space, theroller is removed with regard to the right track or the space track, after which the controller is moved a step forward.
  • the multiple contact groups F1F5 shown. in Figure 6 have their respective contacts I4,
  • Each of these contacts consists of a stationary contact member I6 and a movable contact member having an arm l5 adapted to receive pressure from the roller 5; the contact terminals l3 connected with these contact 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 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.
  • the controller moves forward three times for the first 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.
