Definitions

  • the punching movement may be controlled by a member, preferably in the form of a frame, which is reciprocated by means of an auxiliary force.
  • the receiving magnets may control rail or lever-like intermediate members each of which is located, when the armature of the respective receiving magnet is in one end position between the control member and the associated punch and thus couple these two parts together, and which, when the armature is in the other end position, are not located between these two par-ts, so that they are not coupled and no hole is punched.
  • each receiving magnet armature has an extension which is resiliently movable at least in the direction of punching and the direction of armature attraction.
  • This extension, or the armature itself, may be constructed as a leaf spring and may be twisted between the magnet and its free end through 99.
  • FIGURE 1 is a plan view of parts of a punching arrangement according to the invention, in which the tape and the tape-guiding and -transporting means have been omitted,
  • FIGURE 2 is a perspective view of the components illustrated in FIGURE 1 with only one of the five receiving magnets in position,
  • FIGURE 3 is a perspective view of the receiving magnet illustrated in FIGURE 2, and
  • FIGURE 4 is a perspective view of the frame-like control member illustrated in FIGURE 2.
  • the fast punching arrangement includes a continuously rotating cam shaft 1, by which is driven a framelike control member 2. This member is guided at the points 3a and 3b by means of bolts 4a and 4b in such a way that its upper end, which is directed towards the tape 5, carries out an essentially reciprocating movement as the cam shaft 1 rotates.
  • Five punches 6 each of which is allocated to one of the individual combination elements of the telegraph characters and a thin perforation punch 7 are guided in an upper cross member 2a of the frame 2 and in a guide member 8 which lies above the frame. It is assumed that the device being described is intended for use with a five-unit code and accordingly five receiving magnets 9 to 13 are provided.
  • the armatures 1d of these electromagnetic devices carry extensions 15 to 19 which are formed by leaf springs. Each leaf spring is twisted through close to its free end which is located within the frame 2. The arm-atures are kept in their released positions by springs 20.
  • the lower internal edge of the frame 2 is formed as a stepped comb.
  • each of the five extensions 15 to 19 is freely movable between the associated punch member and the corresponding comb step.
  • an armature is in the released position, the free end of the extension attached thereto lies above the channel 20 formed between adjacent projections 2b.
  • the dashed lines in FIGURE 1 illustrate the positions of the extensions under these conditions.
  • the free end of the associated armature extension is located between the corresponding punch and the associated projection 2b on the lower internal surface of the frame.
  • the free end of the armature extension is also lifted and at the same time this extension is flexed in the region between the point at which it is fixed on the armature and the point at which it is twisted.
  • the free end of the armature extension lies between the top of the projection 2b and the corresponding punch, so that the latter is pressed through the paper tape as the frame 2 rises towards its uppermost position.
  • the armature extension is free to return to the released position under the influence of the spring 2d when the magnet is de-energised, since there is then no axial force gripping the armature extension between the punch member and the associated projection 212. Therefore, the armature 14 can return to its rest position at the same time and the extension of this armature can again be displaced from the line joining the punch member and the projection 2b of the stepped comb.
  • the projections of the comb may moreover be used also as stops for the armature movement. In particular, in the released position of the armature, it is advisable to utilise as the armature stop that lateral limit of the channel which is opposite to the projection with which the armature extension co-operates when the magnet is energised.
  • the guide member 8 is provided with bores 22 and 23 for guiding punches 6 and 7, a surface 24 over which the tape slides and cheeks 25 and 26 for aligning the tape 5.
  • a plate 28 is associated with the guide member 8 and this plate is also provided with bores 29 and 30 which correspond in number and shape to the punches 6 and 7.
  • the advance of the tape 5 is produced through a sprocket cylinder 31 which is driven by a motor (not shown).
  • the drive occurs through the shaft 1, a cam 32, an angle lever 33 and a pawl 34 engaging with a toothed wheel 35.
  • Springs 36 are connected between the pawl 34 and the angle lever 33. It will be appreciated that a friction wheel may be used to advance the tape 5 instead of the sprocket cylinder 31.
  • the embodiments illustrated may be modified in various Ways without departing from the scope of the invention.
  • the receiving magnets may all be arranged on one side of the row of punches.
  • the armatures or armature extensions may be made from round springs or from springs with other cross-sections. The arrangement is useable in a corresponding manner also with those signal storage instruments in which the signals are printed or magnetically recorded instead of being punched.
