I was talking with someone about a Chicago plug. It is not used often, but some VSMs have them. This is the socket for the plug on a Montgomery Ward Streamliner.[ATTACH=CONFIG]570445[/ATTACH]

So, what does it do? Or, why is it there?

bkay, that's where the power goes in from the foot control.

Where can I get a power cord that is a female end with holes. You slip it into a socket that has the pins. The wire from it goes to the wall socket. Help please?

What machine is it for? http://shop.sew-classic.com/ is a good place to find new cords for old machines.

​It is a 1920 Graybar sewing machine. Has everything but the power cord. Wheel turns and needle goes up and down. Everything else looks good for a beginner in this field. Oh the model number is B438500.

Mary, Can you send a pic of the socket? Do you wan t a foot or knee control?

I don't think that is what is called a chicago plug. Singer used that type, a nd it's got a seperate plug for each nob.

This is just what National put on most of their machines. And if you open up the motor, you can rewire it to take a conventional type cord end like japanese machines use.

BTw - the one I showed has a pig tail hanging down from the underside that the foot pedal plugs into. I've got others in cases that have a female end in along side the male end under the motor, and the foot pedal has a longer cord that plugs into along side the power cord. that is why there are two round areas, but only one is cut open for this machine.

I'm pretty sure Chicago plug refers to this type of connection. I have several older Singer machines that use this style, and they are much older than the National machines I have using the two round prong connection. My older Nationals are wired differently.

I have been known to be wrong before. I too have Singers with the plugs like your last picture. Singer plugs remind me of RCA plugs for a/v use. but with more power going through them.
