It is also clear that a safety arrangement exists which prevents the simultaneous excitation of the relays, the excitation of one of these relays R2 for example, interrupting by the blade R2D the circuit through which R1 could 'be excited in the event that the contact 18a would also be earthed, an arrangement lsymmetrical with respect to the foregoing being provided for preventing the excitation of R2 when R1 is excited.

  • Apparatus as claimed in claim 5, further comprising an excessive-speed warning device comprising a series of contact elements electrically insulated from each other and corresponding to increasing increments of speed of the vehicle, a contact member mounted on the speeds head to move therewith and contact each of the contact elements in succession as the speeds head travels over the first recordings, which correspond to warnings of increasing speeds of the vehicle, the contact member having a signal output similar to the signal outputs of the second devices, a further warning recording on said cylinder in said second zone for indicating that the speed of the vehicle is excessive, a selecting element for electrically interconnecting a selected number of adjacent contact elements of said series of contact elements and connecting the selected interconnected contact elements to said second contact means, the interconnected contact elements corresponding to a range of speeds considered excessive, whereby when the vehicle reaches an excessive speed and said contact member contacts said selected interconnected contact elements said second control means cause the defects head to cooperate with and reproduce said further warning recording.
  • an excessive-speed warning device comprising a series of contact elements electrically insulated from each other and corresponding
  • an apparatus for giving sound indications of the speed of the vehicle and sound warnings of any defective operation of said working parts comprising a Iirst device operatively connected to the speedometer to be driven thereby and having a variable signal output varying in accordance with the speed of the vehicle, second detecting devices respectively responsive to defective operation of said working parts and having signal outputs, a sound emitting device comprising a rotatable cylinder, drive means for driving the cylinder in rotation, a series of first recordings of spoken announcements concerning increasing increments of said speed in a first zone of the cylinder, a series of second recordings of spoken warnings each relating to the appearance of one of said operational defects in a second zone of the cylinder, a speeds reproducing head cooperative with the iirst recordings, a defects reproducing head cooperative with the second recordings, irst control means including a speeds motor and a transmission connecting the speeds
