About Tesla's mechanical oscillator, I think Tesla made this device to evaluate the universality that exists between the different mediums. It was more of a "toy" to do experiment I believe. The only other mechanical device I am aware that Tesla worked on was his blade-less pump which he declared has being the most important one he ever did. I think the following readings are giving a hint on why ;)  (for those that don't have a freepatentsonline account and don't want one..
