Thanks!

David, do you have pictures of your "Spotless" engines? I sure would love to add them to the Jacobson registry.
Thank you!

Jacobson sold engines they built under their own name and Montgomery Ward also sold many Jacobson engines under the name "Ward" and "Bull's Eye".

Also, if you have an engine sold by Charles William Store of New York (Maynard) or sold by the Spotless Co. Inc., of Richmond Va., these could be in some cases, be Jacobson built engines. These I also want to add to the Jacobson registry.

Thanks!

Hi Maurice, I think I have pictures of your Unito engine. I did not know it was built by Jacobson. Is there a serial number on the engine?
Thanks!

Dennis,

Here is a photo of a 14 HP Jacobson I own, serial #2546. I have not seen many like this.

We do not realize that many makers of gasoline engines made lots of other things. They did foundry work and machining for others. Sometimes the building of gasoline engines became no more than a sideline.

The attached 1917 article is about the manufacture of Doble-Detroit steam cars where Jacobson Machine Mfg. was to build the car's engines and boilers.

I don't know if Doble-Detroit stem cars were eventually built and if Jacobson built the engine and boiler.

Denis, Wikipedia has an article that seems well-researched on Doble cars, one model of which was the "Doble-Detroit" : http://en.wikipedia.org/wiki/Doble_steam_car

[Denis Rouleau]

I was sent this picture of a page from a Charles William Stores catalog showing the 1-1/2hp Maynard in color. If anyone has that catalog and could scan that page to make it clearer and larger I would like that.

PS: these ads also appeared in either April or May 2004 but I'm missing that issue of the "Gas Engine magazine"

Thanks!

Denis,
Scans on their way.

Does anyone have a rod for a 4 1/2 bullseye?

I've always thought those Jakes were the neatest of the engines they built. I haven't seen many of them and kick myself every time I think of the one selling at auction a few years ago and not bidding on it.

I hope here are two pages from the United Factories catalog showing the Unito Jacobson engine. I endorse anyone to send Dennis pictures and serial numbers of your Jacobson engines. I do not have the computer savvy to set up a registration site.

[Denis Rouleau]

Hi Don, I do not see the two pages from the United Factory catalog here. If you email them directly to me at: buzzcoil2@videotron.ca
I will make sure everyone sees them.
Thanks!

Wayne, this used to belong to dad. It came out of the University of Nebraska where it spent its life as a test engine. It should have had a water cooled pulley and the prony brake shoe and stand on it minus the scale. We never got the scale with it. It was painted gray when we got it. It was originally set up as a natural gas engine. We got this engine along with an 18hp Metz and Weiss from a gentleman named Don from SD. I remember going with dad and bringing them home. Both engines appeared to have been used very little. Both were at Rollag in the mid 70's for several years. Jeff

Jeff,

You are correct in every detail and I did know that it had belonged to your father. I do have the pulley and pony brake shoe that came with the engine and yes they are painted gray. I also have the piece that was cut off where the plate is welded on for the mixer. This piece was given to Jim Johnson by your brother Kevin to give to me a few years back. Thank you Kevin and Jim! Was it your father that cut and welded the plate on for the mixer?

Yes, we did that. Back then we didn't understand running engines on propane and didn't know anybody that did so it was changed to a gasoline setup to get it to run. I'm pretty sure a few years later we would have done things differently. When we had it, it had that gray paint on it but I think it was black underneath. All of the machined surfaces were unpainted. I really liked this engine. I recently referenced it in another thread because of the way it governs. It governs like our 50hp Otto by changing the length of stroke on the intake valve using the valve like a butterfly in a carb. The temperature gauge on the cooling system is all original as it came from the university.
