Type "google patents" in a search bar, and the first hit you get will take you to Google Patent Search. Google and the U.S. Patent and Trademark Office have struck an agreement, and you can now have access to more than 7 million patents, including drawings.
When searching for something and you only want current information, click on the 'search tools' on the left. It opens a list of other features, such as 'Past 24 hours', past week, etc. Try one, then click the search button again and it refines your search to whatever time you chose.
