Les Posted October 16, 2007 Report Posted October 16, 2007 House is 1932, brick veneer, 2 1/2 storey, 30amp service entrance. There are one of these outlets in every room, except baths and kitchen. All are stand alone, except the one over the fireplace. No power in any of them. Most have the plug inserted with no cord attached. Just when I was beginning to think I knew everything!

Richard Moore Posted October 16, 2007 Report Posted October 16, 2007 Les...was there metal or continuity between the prongs in the plug? The only thing I can think of is that they "switch" on the adjoining receptacles (or used to). In that case, you wouldn't measure any current between the two holes unless there was actually something plugged in, and turned on, at the receptacle. Very odd! Ok...just looked closer at the 3rd photo and saw the hole in the plug. Scratch all the above! [:-dunce] I'd now guess for lamp cords but no idea why the weird pattern.
Les Posted October 16, 2007 Author Report Posted October 16, 2007 No, no continuity. Plug cap would accomodate an 18ga lampcord, one steel blade and one brass, both same size, folded stock. I did not remove any wall covers, as the real estate agent was a @#*@$%^ and "don't touch anything, I will ask my inspector. Does he know you?, maybe he will call and let you know what it is." I did good and managed to stop the bleeding from biting my tongue, but I do have a headache! I just have never seen anything like it.
Richard Moore Posted October 16, 2007 Report Posted October 16, 2007 Perhaps they were "shaped" that way to designate a switched circuit for plug in lamps. Just another WAG!
msteger Posted October 16, 2007 Report Posted October 16, 2007 You didn't say if there was any voltage at this odd-shaped receptacle (photos 1 and 2)? I've never seen the sort of receptacle in your photo, but it is a little curious..
Les Posted October 16, 2007 Author Report Posted October 16, 2007 Matthew, no voltage. Just spend the better part of an hour tracking down a Baker Lite electric plug on-line. RESULT: The author really meant bakelite - I just love the world wide web! Where is Katen, Kurt M and Bill K when I need them!
John Dirks Jr Posted October 16, 2007 Report Posted October 16, 2007 Could they be european or other put in place to accommodate travelers who would have brought along smaller personal appliances? Maybe this was a bed and breakfast in the past? Just wild guess....
Richard Moore Posted October 16, 2007 Report Posted October 16, 2007 Les... I found this... http://www.mosaicshades.com/antique2005 ... /index.htm . It's mostly about the history of lamp sockets but if you scroll down to the last photo, the middle plug looks similar. Tough to tell which way the prongs are oriented, but I suspect they went a few different ways until everyone settled on a standard. Interesting article for you lamp socket history buffs.
fqp25 Posted October 16, 2007 Report Posted October 16, 2007 Les, Since there is one in every room, except Bath & Kit. Could it be a receptacle for electric heaters of some kind? Is the primary heat source original? Although, why would there be one over the fireplace? The lamp socket makes more sense.
Chad Fabry Posted October 16, 2007 Report Posted October 16, 2007 When I lived down under in the outback the homes were wired w/ 220 and 24 volt. They had two distinct sets of receptacles for when the generator was running and for running off batteries. It's a guess.
Richard Moore Posted October 16, 2007 Report Posted October 16, 2007 "Plug cap would accomodate an 18ga lampcord, one steel blade and one brass, both same size..." One last guess: The different materials are interesting, and kind of "modern". Perhaps someone worked out the dangers of reversed polarity (power to shell, not switch, etc) and what we have here is America's very first polarized plug? I would imagine the receptacles and "DIY" plugs were sold as sets. Obviously, I had the day off and I'm bored!
Bill Kibbel Posted October 16, 2007 Report Posted October 16, 2007 I've never seen it and the single oblique slot configuration isn't on my chart.
Terence McCann Posted October 16, 2007 Report Posted October 16, 2007 Originally posted by inspecthistoric I've never seen it and the single oblique slot configuration isn't on my chart. Holy cow, if Bill hasn't seen it before must be one of a kind.
hausdok Posted October 16, 2007 Report Posted October 16, 2007 I think it's an old modular telephone plug. The pattern doesn't match anything in any of my charts but I don't have any old charts for telephone equipment. I have a very fuzzy memory of something similar in the abandoned Spingarn mansion where I used to play as a kid. They had those old telephones with the receiver cradle in just about every room. You held the receiver to your ear with one hand, picked up the phone and it's base and held the mouthpiece in front of your mouth with the other and they plugged into wall plugs that looked like weird electrical plugs. OT - OF!!! M.

OT - OF!!! It's way before my time, and admittedly I didn't grow up playing in any mansion, abandoned or otherwise, but I still suspect it's not for a telephone. I doubt that the concept of a phone in each room would have been considered in a relatively modest home such as this. My guess would be some sort of proprietary plug and jack system which never caught on. If you look at the age of the home and the round hole in the plug, I think it was for a power cord for some sort of light or appliance. After all, back in the day, cords were usually cloth-covered and round, right? Thread drift: Why are modern cover plates so boring? Can't we bring back some designs like this one where they have a little character? I'll happily abandon the vertical ribs which are a pain to keep clean, but why not a little filigree work or similar design around the perimeter? Anyone out there with a little spare cash to invest? I suggest we start up a company to manufacture cover plates with vintage design motifs. Craftsman, Mid-century, Art Deco, Nouveau...etc. Any takers?
Les Posted October 17, 2007 Author Report Posted October 17, 2007 I picked the lock on that repo house where the plug and socket is. Pulled cover and it is connected to cloth covered copper wire approx 16ga solid, tinned ends. They are not energized. House had a 30amp service entrance drop from pole and a 60amp main. House was custom built for a local merchant with two main entrances. Full maple floors everywhere, low fire brick exterior, rumsford stove, galley kitchen, popular trims, oak staircase, re-cycled steel I beam with steam pipe supports, no cistern, block foundation, all head room clearances were low with standard single panel doors. The roof is original 1932 slate asbestos shingle and functional. Typical modified four square floor plan. 1 and 1/2 bathrooms with razor blade receptacles. Crane tub and Briggs pedestal sink. I am running out of time with my reputation of knowing "everything". As most of you know, I have a pretty good library of old books and publications and have found nothing. I had the office staff go thru everything and still nothing. Will keep you posted and keep the ideas coming!
msteger Posted October 18, 2007 Report Posted October 18, 2007 Originally posted by Richard Moore Interesting article for you lamp socket history buffs. Are you saying there are actually "lamp socket history buffs"?!?
Les Posted October 18, 2007 Author Report Posted October 18, 2007 Matthew, I must confess that I collect and display everything that has to do with knob and tube "art" and actually sent a weird socket to Jim K last spring. I think Katen has it in his desk and waiting to trade it for some camera lens he has been looking for.
Les Posted October 19, 2007 Author Report Posted October 19, 2007 Douglas H has come to the rescue again!! The device is for radio antennae connection. While he has only seen those that have power, I am going back to house, legally this time, and going to track the wires. Also, if you look at this new larger photo you can see it embossed with "Aerial" on the top and "grounding" at the bottom of the socket. Will keep you posted.

hausdok Posted October 19, 2007 Report Posted October 19, 2007 That makes sense, When I was a kid radios all had some kind of antennae lead or connection point. I suppose at some point prior to television folks could have had their homes pre-wired with an antenna (aerial) system. It also makes sense that it would be a plug that couldn't possibly be confused with a conventional current-carrying type. Bet if you cruise some vintage radio websites you'll eventually find a picture of an old radio with a cord and plug attached. OT - OF!!! M.
MMustola Posted October 19, 2007 Report Posted October 19, 2007 Les, Doug beat to to to punch. Here's a page out of the 1956 Architectural Graphic Standards.
MMustola Posted October 20, 2007 Report Posted October 20, 2007 Mike, I'm working on it. For some reason I'm having touble up loading a PDF file of the page image. How can I re-size a pdf file?
msteger Posted October 20, 2007 Report Posted October 20, 2007 I don't think a PDF file can be reformatted.
Michael Brown Posted October 20, 2007 Report Posted October 20, 2007 Upload to the file manager and then link to that: File Manager Upload It still has to be under 5 MB, how big is it? Michael Brown DevWave Software Inc.
