    I've found the best search tool for patents is usually the USPTO's own engine.

    http://patft.uspto.gov/netahtml/PTO/search-bool.html

    you can search by issue date there as well.

    There are some tricks you can use with Google's patent search to narrow the scope: http://www.google.com/googlepatents/about.html

    OT, leading to small, small tool gloat...

    Has anyone used a particular search tool trying to track down patents?

    Tried the Google beta version and had some success but not exactly the "tool gloat" I will post once I can verify via photos

    Small as it was cheap and not very important but still fascinated me and it has a clear patent Apr date of 7.1925 but files appear to be by date filed as opposed to date approved (makes sense but it opens up a potentially much larger time span).

    Found one very similar and in fact issued a month earlier but with a few very different details that were improvements on a patent issued about a year earlier by the same "inventor". And a patent of a similar type has been issued as late as 2002.
