Welcome to DATAMP!

The DATAMP project is a cooperative effort of the OldWWMachines and OldTools mailing lists. It is intended to be a clearinghouse for information on antique tool and woodworking machine patents, allowing collectors of these tools to easily find information about the history of tools and trades.

DATAMP Frequently Asked Questions

New! We've changed the navigation when displaying patents. Before the patentees names were links to exact matches (matching first/middle/last/suffix). Now we display two links after the patentees names, (exact or similar names). The first link behaves as before, displaying exact name matches. The new "similar " link will pre-populate the person search screen and will display similar, but not necessarily exact, name matches when you press submit. Try the two links out here to see the difference.

The information in DATAMP is gathered from the United States Patent and Trademark Office (USPTO) online database by a group of volunteer "Data Stewards" from the OldTools and OldWWMachine lists. Each steward is responsible for finding and documenting patents related to a particular type of tool or machine, as well as maintaining the DATAMP records in his area of expertise.

Our database is only as good as our volunteers. There are currently 81,713 patents in our database, but there are thousands more patents of interest that await a volunteer to enter the patent information. If you would like to volunteer to help, please contact us! All you need is an interest in old tools or machinery. Previous experience in researching patents is useful but not necessary. All information can be entered via simple web forms. All U.S. patents are already available online, and you need merely transcribe the information into our web form, add manufacturer information and comments (if any), and upload suitable photographs and patent images.
