Definitions

  • the object of the present invention is to produce a talking head which will allow such thickened wire produced by riveting or welding to pass through.
  • the inlet-end of the talking'head is funnelshaped and is closed by two movable jaws.
  • the latter yield, and by means of a small lever arrangement allow the small magnets of the talking head to return quickly into their position.
  • Movable jaws are also arranged at the outlet end of the wire, which movable jaws release a locking device, thereby eifecting a rapid return of the small electro-magnets intotheir normal position.
  • Figure 1 illustrates a horizontal section of the talking head when the wire passes through it, Figure 2 showing the same in elevation, when a thickened portion of the wire passes through.
  • Figure 3 is an end view of the talking head corresponding to the position shown in Figure 1, whilst Figure 4 illustrates an end view corresponding to the position shown in Figure 2.
  • the wire 2 with the thickened points 1 passes through a two-partcasing formed by two plates, 3 and 4, and containing the magnets 5 and 6 for the magnetization of the wire.
  • the guiding of the wire is efi'ected along corresponding grooved guiding members 7 and 8, which are constituted by discs provided with recesses 9 "and 10, the journals 7, 7", 8, 8" of the discs being formed with screw threads running in opposite directions.
  • the said screw threaded journals engage in corresponding screw threaded counterparts formed in the plates 3 and 4. Vhen the discs 7 and 8 are rotated in opposite directions, the plates 3 and 4 must either approach or recede from one another.
  • discs 7 and 8 are coupled together to rotate in opposite directions, this being effected by means of toothed segments 11 and 12 which are mounted on the screw threaded journals 7 and 8 respectively. If a thickened part 1 of the wire runs towards the left over the disc 7 it strikes against the edge of the recess 9 and consequently turns the disc 7 in such a direction that the plates 3 and 4 of the talking head are moved away from one another. This causes the disc 8 to be rotated in a symmetrical position (see Figure 4), by the cou ling through the segments 11 and 12.
  • a reproducing magnet or talking head for telegraphones capable of allowing the passage of riveted or welded thickened parts of wire, comprising movable jaws carrying the magnets of the telegraphone and having a funnel-shaped inlet end, in combination withmeans provided at the inlet and outlet end of the talking head for respectively positively opening and closing the said aws under the control of the said thickened parts of wire.

  • movable jaws carrying the magnets of the telegraphone and having a funnel-shaped inlet end
  • means for respectively positively opening and closing the said jaws under the control of the said thickened parts of wire the said means comprising grooved guiding discs having recesses, screw-threaded journals mounted with the screw-threads running in opposite directions in the movable jaws on which the said guiding discs are mounted, and toothed segments secured to the screw-threaded journals and in toothed engagement with one another, as set forth.
