I think you can narrow it down to a Schwinn, as the badge in front matches Schwinn. Those emblems are for sale on ebay. If you look at Schwinn bikes sold (worthpoint.com, dont need an account to see pics), seems to match up with 60s bikes generally. You could probably narrow it down further comparing pictures of your bike with ones sold at worthpoint. I dont know enough about bikes to comment on the sprocket.
