784. Is an adding machine patented by Charles Henry Webb of New York, NY.

Took me fecking ages to find it but if you go to the US Patent Office
website and type PN/414959 into the advanced search

http://patft.uspto.gov/netahtml/PTO/search-adv.htm

you'll see it. Select years '1790 to date' first.


Thanks for taking the time to find that, I appreciate everyone's help in
researching the tools that I post each week.
