Polling and external web service every few hours

HI   our company is doing order fulfillment using a remote warehouse.  

I have created code to upload the orders to the  Warehous's remote web service via HTTP Callout but I need to know:

Q) How can we create a batchable like Class that just polls the web service for results via GET  every few hours?

I really don't need to use the database.querylocator start(Database.BatchableContext BC)   method to batch load objects for the execute(Database.BatchableContext BC, List<scope> scope). 

 Thanks
