This is the original model that was submitted by George Campbell to the US Patent Office in 1865 to show the details of his invention.

The models were required by the Patent Officer in order to establish the merits of a patent request.

This washing machine was patented #52,265 on 30 January 1866. The model bears the original signed patent tag as well as the inventor's tags. It matches the machine in the original paperwork.

Copies of the original documentation is available at Google Patent Search online:

I purchased this particular example from Cliff Petersen. At one point Cliff Petersen owned the largest collection of patent models in the US. His purchase of a huge crated group of models saved thousands of models from obscurity and possible destruction.

    Wow!! What a fantastic collection you have. Patent models intrigue me. This is the neatest washing machine model I've seen.

    Thanks gatekeeper. I love yours as well.

    Most of what is in private hands today came through the Cliff Petersen collection-- probably where yours came from!

    I have a wonderful steam valve patent model from the 1860s. It never reall occurred to me to wonder how it came to be on the market, thanks for the info! Yours is awesome!

    Thanks Stef-- post yours, I'd like to see it.

    Originally all of the patent models were auctioned and set to be scrapped. Luckily Petersen bought them all with the hopes of opening a museum someday, but that never happened.

    I bought mine through him in the early 1980s! I wish that I had bought more!

    I've found similar patent models on proxibid. I'm not saying anyone should go there and buy them. I'm just saying that I've seen some there before.

    Patent models are a popular collecting field-- they usually bring very good money when offered for sale.
