Are you looking for Database.executeBatch method returns Type
1) https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_batch_interface.htm
The Database.executeBatch method returns the ID of the AsyncApexJob object, which you can use to track the progress of the job. For example: 
ID batchprocessid = Database.executeBatch(reassign);

AsyncApexJob aaj = [SELECT Id, Status, JobItemsProcessed, TotalJobItems, NumberOfErrors 
                    FROM AsyncApexJob WHERE ID =: batchprocessid ];

If you are looking for Batchable Interface Method return type
2) https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_interface_database_batchable.htm
Public System.Iterable start(Database.BatchabelContext bcon)
Public Database.QueryLocator start(Database.BatchabelContext bcon)
Public void execute(Database.BatchableContext bc,List<Sobject> scope)
Public void finish(Database.BatchableContext bc)

Let us know if this will help you

Thanks

How is the Start method able to return two different return types? Iterable or QueryLocator. 

As far as Function Overloading is concerned, methods can be overloaded based on different input parameters. But its not possible to overload a method based on different Return Types.
