ENGAGEMENT DELAY FOR A PUSH BUTTON CONTROLLED VOLTAGE GENERATOR FOR A DUAL BAND ELECTRONICALLY TUNED RECEIVER

摘要

A ratchet engagement delay for a tuning voltage generator having a first turret for supplying a voltage for tuning a radio receiver in the AM frequency band and a second turret for supplying a voltage for tuning the radio receiver in the FM frequency band. A first ratchet mechanism has a driven member secured to the first turret for rotation therewith and a drive member which is rotated by a first push button actuator. A second ratchet mechanism has a driven member secured to the second turret for rotation therewith and a drive member which is rotated by a second push button actuator. A ratchet engagement mechanism is responsive to the actuation of the first push button actuator to engage the drive and driven members of the first ratchet mechanism after initial rotation of the driven member and responsive to the actuation of the second push button actuator to engage the drive and driven members of the second ratchet mechanism after initial rotation of the drive member to provide a ratchet engagement delay upon the first actuation of the first or second push button actuator after the other of said actuators has been actuated.
