This is a Todd Engine mfd. in Warren Pa. -only one known. You can tell that it is a Jacobson. 1 1/2 hp. There is a different mixer on this engine. The serial number is a Jacobson number.

[Don Worley]

Denis; This may be what you are looking for. The Southern Planter July 1,1923.
Jacobson Owners please post your serial numbers!

Don heres some pictures of another jacobson that i know of.
unfortunately its not available [yet]. it has all of its orginal paint covered with thick grease. how rare was this model, its the only one like it ive run across.

[Don Worley]

One with the mag bracket is more uncommon. It does look original down to the starting crank and skids. Should take the square gas tank and can muffler. Too bad you didn't clean off the serial number.

Bob, any chance you obtain the serial number off of the name tag? It would be interesting to know when it was built.

Don, was Todd an engine builder or a selling agent?

I will have this post and some following to help people with the restoration of their Engines, In that I will show the pin stripping found on the Jacobson my father and I own.

I hope this is helpful to those that are curious about this.

The first 3 photos show the water hopper, and the last shows the crank guard.

Front View, Muffler side view, Side Shaft Side view (with tags)

The base, flywheels, crank guard, everything except the Water Hopper and the Wood Skids have NO pin striping and are just a dark Red / Brown Color.

My next post includes pictures of the Wood Skids.

[Chris J]

Here are some pictures of the Original Skids.

I hope this helps someone!

And Lastly,

A view of the Entire Engine, and a video of it running after many hours of work, still a few more bugs to work out, but I left for work and then college again.

I really like these Jacobson Engines, even though we haven't been a Jacobson Engine owner for too long.

Enjoy!

As far as I can tell, Jacobson sold 1 1/2 hp engines to local people to sell on their own. The Todd engine is an example. Whether the tag was stamped at the plant is unknown.

[Denis Rouleau]

Here is an email sent to Don, with information on some Jacobson engines sent to Australia in 1912-1913.

Also, I received indication from New Zealand that Jacobson's No. 12906 and No. 16752 had made it there in about 1917-18.
The 2 engines have Jacobson name tags and pictures are included in the registry here:

Looking at the registry list, it appears like the engines were manufactured in batches of a given size. Even with large gaps in the number sequences, long series of individual engine sizes are evident.

Yes toward the end of the production.

Jacobson had several plants and associated companies- see list. The plant in Chester Pa. made the larger engines. See the plate from Carpenter and Diederichs Internal Combustion Engines. The setup on this style of throttling Jacobson is very similar to the "Warren" engine by Struthers Wells and the Fairchild and Betts engine which were both designed by Charles.

One concern I have is that 100% of Jacobson built engines from 1912 to 1915 inclusively were tagged as "Ward" and "Bull's Eye" and sold by Montgomery Ward. You would have thought that Jacobson would have sold some engines under their own name in all these years.

You must remember that Jacobson Warren was a small operation. If you look at the 1917 pictures there aren't that many employees. A good number of the workers were in the gear portion of the operation. If a small company like Jacobson got all the Wards engine business they probably didn't have enough engines left over to put their own tags on them.

As a side note: My website has been up for several years and has in that time received 14400 visits. This thread which is 2 months old has now surpassed my site in visits. I think that this thread and the registry has greatly increased knowledge of my hometown industry- Jacobson Machine. Thanks Denis

Don, a big thank you goes to you for sharing your knowledge of Jacobson engines. Because of it we have all learned a thing or two about Jacobson engines.

There are several more engines that need to be included in the Jacobson registry and there is a lot more Jacobson literature out there. Many here have been great by registering their engines and providing us with old ads and other relevant literature. We have an ongoing project and I encourage people to keep it going.

The big question remains: "When was my Jacobson built"? We never will be able to say when with 100% certainty but in the coming weeks I will try to fill in the blanks in the registry of the column "estimated year built".

Keep the ball rolling and register your Jacobson engines!!!

Phoenix Iron Works in Meadville PA. was licensed by Jacobson to produce heavy duty engines. If you look at the picture you can see that the Meadville on the side of the engine has been removed for sales purposes. You may also notice that this is another view of the twin tandem engine.

[Don Worley]

Don't know if I have posted this one. I believe it is a 7 hp on factory cart about 1912.

[Don Worley]

Another example of a Jacobson Sturdy Jack sold by another Warren company. I know of none of these to exist.

[Don Worley]

I am showing the 3 types of Sturdy Jack 1 1/2 hp engines.
First in line is the battery and coil engine. The governor is on the timing gear. The exhaust comes out the top of the head. These are set up like the Maynard engines. The spark is run off a contact on the timing gear.
Second is the Webster magneto engine. It takes an MM mag, bracket no. M 22 The exhaust comes out the bottom. The governor weights are in the flywheel.
Third is the Webster mag engine that has a spark plug adapter and contact points run off the pushrod. This was run with battery and coil.
I believe that the mag type engine was mostly later in production. They could have both mag and battery and coil off the same design.
