Definitions

  • This invention provides for the automatic startlng and stopping of a radio receiver, whereby a set otherwise tuned may be brought into action at a predetermined time to re ceive a desired program, or may be cut off at a given time when further reception is not required. Thus, a certain program may be received and further reception cut off after the elapse of a certain period of time.
  • an ordinary alarm clock of any make is employed, and the hammer is included in the filament circuit of the radio receiver to nia-ke or break the filament circuit as required.
  • a controlling switch is included in the time circuit and may be set to start or stop the receiver, or adjusted to a neutral point as the occasion may demand.
  • Figure 1 ⁇ is a top planview of a mechanism embodying the invention.
  • Figure 2 is a schematic view, illustrating the circuits.
  • the numeral 1 denotes an ordinary alarm clock and 2 the usual hammer thereof.
  • spring contact 3 is mounted upon the frame of the clock adjacent the hammer 2, and is connected to a binding post 4, which is attached to the clock frame but electrically insulated therefrom.
  • a clip 5 is attached to the binding post 4.
  • An arm 6 is attached to the frame of the clock adjacent the hammer 2, and is formed with a hook 7 which is adapted to engage a stop 8 carried by the hammer 2.
  • the arm 6 is connected to the binding post 9.attached to and electrically insulated. from the frame of the clock.
  • a clip 10 is attached to the binding post 9.
  • the hammer 2 is disposed between the contact 3 and arm 6 and is normally in engagement with the Contact 3.
  • a binding post 11 is mounted upon the frame of the clock and electrically insulated therefrom.
  • -A pig tail 12 or other fiexiblo conductor connects the binding post 11 and hammer 2.
  • the numeral 13 designates a suitable base upon which the alarm clock 1 is mounted. Binding posts 14 and 15 are mounted upon the base 13. A switch is likewise mounted upon the base 13 and comprises taps 16, 17 and 18 and a pivoted arm 19. A wire 2O conneet-s the tap 18 with the clip 10. A wire 21 connects the tap 16 with the clip 5. A .wire 22 connects the binding post 15 with the pivoted arm 19.
  • the numeral 23 designates a radio receiver which may be of any make.
  • the receiver is of the type including tubes.
  • the terminals of the filament circuit are designated 'by the numerals 24 and 25.
  • the usual A-battery is designated by the numeral 26.
  • a wire 27 connects one pole of the A-battery with the filament terminal 24, and a wire 28 connects the other pole of the battery with the bind- 75 ing post 15.
  • the wire 29 connects the binding post 14 with the other terminal 25 of the filament circuit.
  • the mechanism appears substantially as shown in Figure. l of the drawings, and may be used in connection with any radio receiver including a filament circuit. It is only necessary to connect the binding posts 14 and 15 with the A-battery and filament circuit substantially in the manner herein indicated and shown in Figure 2 of the drawings.
  • the switch arm 19 When the switch arm 19 is moved to connect with the tap 17 the switch is neutral and the timingmechanism inactive. As hereinbefore .stated the hammer 2 is normally in engagement with the contact 3, and when the switch arm 19 is adjusted to make contact with the tap 16 the filament circuit is closed, and the radio receiver 23 in condition for reception.
  • the circuit is as follows: Starting at the tap 16 the current 95 Hows through the wire 21, contact 3, hammer 2, wire 12, wire 30 between the binding posts 11 and 14, wire 29, filament circuit of the radio receiver in the manner well understood, thence'through wire 27, battery 26, wires 28 100 and 22, and switch arm 19 to the contact or tap 16.
  • an alarm clock a inding post on the frame of the clock, a flexible conductor connecting the binding post with the hammer of the clock, contacts at opposite sides of the hammer and forming termlnals ofthe circuit to be closed or broken by the hammer, one of the contacts being normally in engagement with the hammer, and interengaging means between the other contact and the hammer ⁇ to hold the latter when moved from a normal position.
  • the radio receiver may be set to start at a given time or when started to stop at a predetermined time, without requiring any particular attention, other than' setting the controlling switch.
  • a timing mechanism for making and breaking a filament circuit including ⁇ an alarm clock having its hammer ⁇ element forming a part of the circuit, contact elements at opposite sides of the hammer element and forming parts of the circuit, a switch for setting the circuit to start or stop the mechanism controlled thereby, andv Stop means to engage the hammer element when moved from one of the said contact elements to the other and holding it in the engaged position.
  • An electric timing mechanism including an alarm clock adapted to have its hammer
