What kind of engine is this?

[Nickademusss]

Found this little gem at a antique store today marked as telegraph equipment, it does run off of a 9v battery, I plan on restoring it. The only markings are on the connecting rod, it says Pat D May 17 1910, its 5" long 2.5" wide with a 2 3/4" fly wheel. With a forward and reverse lever....

Anyone ever seen one of these?

I have seen a lot of solenoid engines, but that may be the oldest one I have ever seen.

Nice find! Thm:

Thanks Chuck, Now I know!

Great little 15$ find!

That is about enough to get me in-to building an "engine".
I wonder what sort of contacts and how the speed control works.
The rest is no problem.
To the OP can you determine the mechanism involved?

I sold a motor of that exact type on eBay a few months back. My example had the same patent date. It was a bit cleaner with nice paint and perfect wiring. It'll run on just about any voltage greater than 2.5V. A couple of D-cells will have it ticking over nicely.

Mine sold for something like $250... Your $15 find is probably worth $200 in its current condition.

The only reason I sold mine was because I am personally not interested in solenoid engines.

I built one of these from the patent documentation. You are lucky to find an original one.

WOW thanks for the info, I will carefully restore it, and it will live on. I am just glad the coils dont need to be rewound.

their are some numbers on the bottom I noticed today, 1012 is what it says, could that be the cast date of the base, october 1912?

I also think it needs a nice wood base with a battery compartment.

Great looking engines!

 

[Nickademusss]

got it cleaned up and running smoothy!

Looks like something from a high school physics lab.

It does! I am just stoked to have a 100 year old electric motor, after cleaning and oiling, it will run very slowly on a set of AA batteries or fast if you want...

I have some contact lubricant that made it run better as well, I think the little brushes will last longer with it on them.
