An electronically operated lock has a latch mechanism which is operable by a rotatable spindle. The spindle can be rotated manually either by an inside turn lever or a key operated outside plug or rotated electronically. A pinion is secured to the spindle and a slider supported for vertical displacement has a vertical rack which cooperates with the pinion. The slider has vertically separated upper and lower control surfaces and a rotatable wheel gear has an eccentric axially extending finger located intermediate the upper and lower control surfaces. The wheel gear is driven by a single direction motor through gearing. The upper and lower control surfaces are selectively located so that when the finger is rotated in one direction from a 3:00 position to a 9:00 position, the displacement of the slider will displace the bolt to the retracted position and so that when the finger is rotated in that direction from the 9:00 position to the 3:00 position, the displacement of the slider will displace the bolt to the advanced position.

[ I claim:] [1.] An electronically operated lock comprisinga latch mechanism including a bolt and bolt actuation means having a rotatable actuator for displacing said bolt between advanced and retracted positions,rotatable spindle means for rotating said rotatable actuator,turn lever means for rotating said spindle means from the interior of a door to displace said bolt between said advanced and retracted positions,key operated plug means for rotating said spindle means from the exterior of the door to displace said bolt between said advanced and retracted positions,electronically operated means for rotating said spindle means to displace said bolt from said advanced position to said retracted position includinga pinion secured to said spindle means,a slider supported for vertical displacement and having a vertical rack cooperating with said pinion,said slider having vertically separated upper and lower horizontally extending control surfaces,a rotatable wheel gear having an eccentric, axially projecting finger located intermediate said upper and lower horizontally extending control surfaces,a motor,gear means for connecting the output of said motor to said wheel gear,said upper and lower control surfaces being selectively located so that when said finger is rotated in one direction from a 3:00 position to a 9:00 position, said finger will displace said slider to displace said bolt to said retracted position and so that when said finger is rotated in said one direction from the 9:00 position to the 3:00 position, said finger will displace said slider to displace said bolt to said advanced position.
