Definitions

  • the invention obviates the necessity of switch over devices by the provision of an electro-magnet, directly or indirectly energized by the sign impulses, with a number of separate armatures corresponding to the number of the combination elements (for example 5) and controlled one after the other.
  • the adjustment of the armatures takes place by means of controlling devices which are moved in turn by the shaft of the receiver, rotating once for each sign. According to the condition of excitation of the electrdmagnet there is a position of the controlling devices which corresponds to therespective combination element and which is in known manner transmitted to. selector bars in combination with type levers for the purpose of printing the sign.
  • the apparatus can be so made that the armatures are brought in turn into their attracted position and so held by the eleotro-magnets if these are simultaneously 7 energized. Very small current strengths are sufiicient for this purpose.
  • Figure 1 shows the apparatus for releasing the shaft and adjusting a selector bar, in elevation
  • Figure 2 shows a plan of the signal magnet common for all bars.
  • the horse shoe shaped magnet 1 has a winding 2, which may be connected directly or indirectly to the trunk line.
  • armatures I, II, III, IV, V
  • each of which is drawn away from the magnet by a spring 1.
  • a selector lever 5 In front of each armature there is a selector lever 5, which is rotatably carried on the shaft 6.
  • Each selector lever has a nose piece 7 which engages with a cam 8 which with the shaft 9 makes a retation witheach transmitted sign.
  • a powerful return spring 10 draws the selector lever 5 into its normal position against the stop 11 when it is not held by the projecting piece 12 of the lock 13 which is situated in front of all the levers.
  • the selector lever On a third arm 28 the selector lever carries a blade spring 14, which, accordingto the position of the selector lever, effects a displacement of the selector bar 15 to the right or to the left.
  • the movement of the bar is limited by a stop 16.
  • intermediate pieces 17 can drop in known manner, which,
  • the sign acting on the winding 2 consists, for example, of current marking impulses for one, and current pauses for the other adjustment of the selector bars.
  • the cams 8 are so distributed on the circumference that on the rotation of the shaft 9 the selector levers corresponding to the armatures I-V are in turn actuated at the same intervals of time in which the separate current marking impulses follow each other.
  • Figure 1 the adjustment of the armature I and the parts appertaining thereto is shown.
  • the stoppage of the shaft 9, which is connected by a friction. coupling with a continuously rotating motor shaft, is effected by means of .the stop 21, which rests against the projecting arm 22 of the pawl 23.
  • the stop 21 is on an arm 2 1 which is connected with the shaft 9.
  • the pawl 23 is rotatable about the axis 25 and is so formed at its lower end that it bears with five projections26 against all five armatures. As long as the stop 21 rests on the arm 22 the projections 26 rest against the armatures, and these are held by the magnet which receives anorinalcurrent during the pause between two signs.
  • a polarized magnet system can, however, be used just as well, which retainslts armatures even with the line current switched ofi.
  • the sign transmission can then be providedaccording to the character of the magnet system for working current or also for double current.
  • a line relay can also be used, controlled by the line currents and which transmits the sign impulses to the magnet winding.
