Automatic starting device for automotive engines and the like

Claim 1

An automatic starting device for automotive internal combustion engines and the like which includes a battery and a battery charging means together with an ignition circuit, an electric starter, a starter solenoid circuit for energizing said electric starter, an accessory circuit for energizing electrical automobile accessories, and an engine intake manifold in combination with an electric motor operated clock timer having a revolving clock member and a plurality of circularly arranged setting pins incorporated in and dividing said clock member into equal time increments, normally open switch means selectively operable by any one of said setting pins to close said normally open switch means at a preset time and for a first predetermined time interval, said normally open switch means being connected on its one side to one side of said battery, and on its other side through a first circuit to the starting solenoid circuit, through a second circuit to the accessory circuit, and through a third circuit to the ignition circuit, a normally open relay switch in said first circuit, a first electronic timing means operable after said normally open switch means is closed for alternately closing said normally open relay switch for a second predetermined time interval and for opening said normally open relay switch means at the end of said second predetermined time interval for a third predetermined time interval in continuing sequence, said normally open relay switch means when closed operatively connecting the battery to the starter solenoid circuit for starting said engine, and a second electronic timing means for deenergizing said starter solenoid circuit after said normally open switch means has been closed for a fourth predetermined time interval, said fourth predetermined time interval being less than said first predetermined time interval, and greater than said second and third predetermined time intervals.
