Help with Marx engine1666

[Sarah110]

I took the engine apart to see if it needed lubrication. A copper piece shaped like an 'l' bracket fell out as I was taking the motor out. I don't see an obvious place for it. Can anyone help me?

Here's a picture of the motor and copper piece:

Some Marx locomotives were equipped with a very crude "chuffer" that consisted of a metal spring that was placed crosswise in front of the motor. The end of it rubbed against one of the connecting rod ends to make the chuffing noise. Look to see if it will fit in the body somewhere around the cylinders when you put the motor back in place. That is the only use that I can think of for that metal part... hopefully some of the more knowledgeable members can chime in with some ideas. - James

By the way, if it is the metal "chuffer", the engine will run fine without it.

Thanks! I was able to attach the piece as you suggested.

Good! Always glad to help another Marx fan. - James

Nice find.  The 1666 with the "choo choo" sound is one of the few actual "rare" Marx locomotives.  The shell should have a plastic panel inside  the steam chest.  The side rod activates the spring (copper piece) which taps the panel and produces the rhythmic sound of a steam locomotive.  Some say crude, others clever, in terms of the design.  Whatever, it works pretty well.  It was most commonly used on the little Marx 490 engine.  It is a wonderful example of the simple, creative thinking that added so much play value to Marx trains.
