Welcome to the United Gasoline Engine Registry. This site will be used to document everything that the United Engine Company sold. This site is constantly under construction and will be updated as engines are submitted. This website will include all names that United sold hit and miss or throttle governed engines under and will also include other equipment such as cream separators, washing machines, buzz saws, and even radios. Please use the tabs above to navigate this new site. With this redesign I hope that the site is more useful and hope to continue promoting the history of the United Engine Company like the registry keepers before me. If you have any problems using the website or would like to contact me, please use the Contact page.

Latest Updates!

A 2-1/2hp Type A throttle governed engine surfaced in Thailand recently with an unusual mixer and factory Wico EK ignition. Interestingly, the engine 2 numbers below it is a regular hit and miss engine in USA with none of the oddball features. It can be seen on the registry. The serial is 205691.

Major Update!

I have partnered with Keith Smigle and will be hosting the Associated registry and information as well. Please continue to submit your Uniteds as you have previously and in the near future start to register your Associateds! It will take a bit of time to get everything uploaded and replicated but in the end I plan to have a mirrored site for United and Associated engines. Please excuse any blank pages or issues in the meantime with the site. I will be updating the sections live as to not interfere with anyones viewing. I'm happy to help keep the Associated history alive.

Number 800!

We now have 800 United Engines registered. Thanks to everyone who submitted their engine and thanks to the former caretakers for all their hard work in getting us here. This is the 800th submission, also the latest engine on record with the 'Makers' tag.

A Type B engine was found in a collection on Long Island, NY which prompted another being discovered in Michigan! We now have 4 of these rare Type B United engines on the list. Only one of them has a tag and still no positive ID on the builder, although I heavily suspect Field & Brundage. They can be seen on the serial number list.

Happy New Year! Thanks to a donation from a fellow collector we now have a United Parts Bag mailer that appears to be a leftover, never mailed. We've also listed a beautiful original paint "Johnny Boy" model United and that can be seen on the registry, serial 251890. There are also photos of a new United fold out advertisement in the literature section. If you own this piece (it was recently sold at auction) I would love to chat with you. As always, I'm looking to expand every section of United so if you have anything to share (photos, copies, stories) feel free to send me a message.

I've been able to add a real Diabolo No. 2 Cream Separator to the Other United Equipment. This was shared on Facebook. This is the first United Engine Co. Cream Separator I have on the list and interested in seeing more! This No. 2 separator was rated for 550-600 lbs per hour and cost $31.50 in 1915. That would equate to $788.36 in 2019. More details on the separators are available in the Advertising section.

Thank you to Michael Sands of Iowa for graciously providing high resolution copies of two United letters, a fold-able brochure, and a saw blade flyer.

I've added a few new advertisements as well as reorganizing the Serial Number List. I've added approximate dates to the engines. There are still no factory records available but I was able to put a guess towards dating based off research. If you have anything that could help date even a single engine it would be greatly useful and appreciated.

Happy New Year!

Minor formatting edits on Timeline and Other Equipment Lists

October 2, 2018

We have new information regarding the end of the United Engine Company. The following was provided by Tim Tackett.

"Researching Farm Implement News Buyers Guides, the last year that United Engine Co. was listed as supplying gas engines was 1931. In 1932 they were no longer listed as supplying engines, AND Associated Mfg. Was listed first time as supplying repair services for United Engines.

United continued to be listed as providing repair services for manure spreaders, washing machines, cream separators, etc all the way up to 1947 but from 1942 to 1947 there listings dwindled dramatically with only two listings in '47. That is last year of buyers guide I have found from source I was researching. "

Thank you Tim for the research! The United Timeline has been updated to reflect this information.
