Selective programming control system for tuning and recording

Claim 1

In combination with a control device associated with one of a plurality of electrically powered devices and a source of electrical energy, a programming mechanism comprising a timer motor, a plurality of stationary interval segments, current conducting means driven by the timer motor for sequentially connecting the source to said interval segments, a plurality of voltage supply lines respectively connected to the interval segments, a plurality of position selecting conductors, position selecting switch means for connecting each of the voltage supply lines to each of the position selecting conductors, a positioning motor connected to the control device, a plurality of normally closed control switches respectively connected to the position selecting conductors, switch actuating means driven by the positioning motor for sequentially opening the control switches, motor controlling relay means connected to the control switches for energizing the positioning motor from said source until one of the control switches is opened by the switch actuating means, first power controlling relay means for energizing another of the electrically powered devices from said source, interval selector switches connecting the voltage supply lines to the first power controlling relay means for continuously connecting said other of the powered devices to the source to energize the same only during a selected timing interval, second power controlling relay means connected to said position selecting conductors for energizing said one of the electrically powered devices during the selected timing interval, and capacitive delay means connected to said second power controlling relay means for prolonging energization of said one of the powered devices for a fixed delay period upon termination of the selected timing interval.
