Hello collective wisdom,

I've restored this Webster Chicago wire recorder. It has a odd shaped two prong outlet on the side that is intended for a foot switch/pedal. You'll see from the pics that it looks like a little two-prong power plug, but one of the prongs is at an angle, and it says "antenna" and "ground" on it. I know that it isn't for an antenna and ground! If I rig up a switch and stick it in there, I can start and stop the player just fine. If anyone can ID this plug, I'd be grateful. I'd like to rig up a footswitch for it, just for kicks.

For the real hardcore Webcor fans out there, I actually have a Webster Chicago "two-way" dictation pedal. It works with later models and has a three prong plug on it. Anyone know about this weird two-pronger? I'm just dying to dictate some memos!! Now I just need a typist....

--Brian

Hello, it may show up on the parts list. I vaguely remember seeing one marked eagle, somewhere, maybe that will help.

Found similar receptacles in this write up, scroll down to items 19 and 20. No images of the matching plugs.

And RadioTVNut had a plug at one point in time. Hopefully he didn't store it in his basemant.

Eureka! That's the one: #20 on the plug socket museum site.

"Radio outlet designed by Victor R. Despard. Patent application was filed in 1932 by Pass & Seymour Inc. in Syracuse, N.Y. Outlet has been made also by Bryant Electrical Corporation in Bridgeport, CT."

Now I don't suppose any is still manufacturing plugs for those things? :D

Thanks for the quick ID! You all are amazing.

The form factor looks like a Despard electrical device, maybe that will lead you in the right direction to finding one?

A lot of the receptacles/sockets have survived, many still installed in the walls of old houses since back in the day when they were more commonly used for radio antenna and ground.

That's a very unusual use for it, but it would serve the purpose of being able to disconnect the foot switch when it was not needed.

Unfortunately almost no plugs have survived. I'd try taking a standard 120 volt plug with a rubber body and flat prongs, and twisting one to mate with what you have.

Hard to tell the exact scale from the picture but it looks very similar to the standard (2 contact) AC mains plug with one contact oriented at 45°. If the size and contacts spacing are identical you may try converting an old AC mains plug by bending (twisting) one of the two contact blades at 45° with a plier.

Or buy a 120V 20A plug, which has one prong twisted 90 degrees.
