Don, any idea as to what years the 2hp pump engines were built and were all 4 types available at the same time or if one style replaced the other?
Thanks!

Two factory photos used by sales agents. Pump engine.

[Don Worley]

I believe that they were sold between 1912-1916. The cogwheels seem to have been first and the pushrod later. I also believe that most all the castings were done in 1912, thus the5000s serial numbers. Once again this is supposition.

Here is a new page covering Jacobson's Sturdy Jack 2hp Pumper engine:

I want to thank Don Worley as the 4 engine pictures he took and the vintage photos are from his collection.

Here is a photo taken outside the factory for sales purposes. It was to show how easy it was to move. Yes, once you got it up that high.

Don: That looks like you

I know I'm old but not that old.

Newer style air compressor. They also had an older style previously posted on this thread and a compressor made out of the 1 1/2 hp engine as seen on another Jacobson thread.

I believe Charles Jacobson Moved to Jamestown in 1906.

Don Worley told me he only saw one screen cooled Jacobson. Anyone else have one or seen one?

I have been trying to buy this engine for the last 10 years, but the old guy will not sell it. This engine is in New Zealand. Enclosed is 4 photo's of the engine. The brass Serial Number plate is missing. I'm sure the old guy has the brass Serial Number plate. Is it a Jacobson Engine? What HP is it please? It has a guard rail next to the flywheel on one side only. The engine is 100% original, with the magneto ignition. The other brass plate on the states that engine is less than 5HP. The Underwriters Laboratories No is: 3552. Does the 3552 number date this engine please? Regards from Geoff McCarten.

This would be a Bullseye engine. Probably around 1914. Hp 4 1/2. The indentation on the cylinder water jacket wall is the hp indication. Has the Accurate mag option. A green engine should indicate it originally was on a cart, but the engine has been repainted somewhere along the way. The skids are original paint. This is one of the supposed 7 Jacobsons in New Zealand. Hope you are enjoying your New Years Day. Serial number should be on the end of the crank.

Record possibly of the Wahl engine. Would be nice to hope.

Its heavy! If you would like better pictures for your website, I can e-mail you full sized copies when I'm back at school where the fast internet is if you would like.

I hope these pictures help some!

Thanks Chris, your pictures will do just fine for yet another page on Jacobson stuff.

Thank you very much!

Everyone!!!
I am still looking to add your Jacobson engines to the Jacobson registry. I also want to add any ads or other related literature. Show me what you have!
