A special thanks to David Bates and his lawyer friend, David V. Carlson, in getting this information on the patents of Joseph Corbett and Dee Forest Bates for giving me the information and the suggestion to post it on the internet for all to enjoy. I remember Thora telling me about Joseph Corbett and his envelope making machine. Now we can actually see what Joseph Corbett's patents were in drawing form. Also, from "One Line of Bates Men" and written by Irene Corbett Nielson, you can read "The Story of Joseph Corbett and Sarah Frost".

Please note that the following is just the first page of the specifications and drawings for each patent. In order to view the following documents, you will need to have the Adobe Acrobat Reader.
