Any idea what this is???

BryanSayer | Posted in Photo Gallery on July 8, 2006 07:04am

So this round metal disk is in our wood floor in the dining room. It is close to be centered in the room, but not quite. The floor finishers said they never saw anything like it.

So, any ideas?

    It's a cleat,  to secure a pole in the middle of the floor.  It has a threaded hole in the middle,  right?  Maybe for indoor badmitton net or a GoGo dancing pole?

      OK, I think I like the Go-Go dancing pole idea best...

          Seems like flappers would have been more likely. Now I just have to find the bathtub gin stash. But I guess that explains the huge tub we have.

  2. gbwood | Jul 08, 2006 07:44am | #2

    what appears to be indentations in the surface would accept a spanner wrench, which may indicate it being a threaded plug. Maybe to accept one of those cool patio umbrellas? or a tetherball pole?

     

    dunno...

    Unscrew it and find out.

    You gotta use a pin wrench. Basically a metal bar with two pins through it in the right place to stick in two of those holes.

    It looks like an old screw on cover for a gas or steam valve.

      I've got an adjustable pin wrench. Bicycle bottom brackets used to require them. Not sure now with the huge technology changes in bicycles.I've got to check for the threading. Calling for the help makes sense, but I was kinda hoping it was THE button. You know the one people talk about? "The president has his hand on the button" or "she knows how to push his buttons".

      There was gas lighting here. I've kinda wondered about a gas candleabra thing for the table.Or a big lazy susan, like they have at chinese restaurants.

    It's what is left of a footswitch, usually hooked up to a ringer that alerts a maid or butler.

    1. Stuart | Jul 08, 2006 05:11pm | #9

      I think you're right, it's the remnants of an old footswitch used to call the maid or butler.  I have something similar in my house.

      BTW, do you own an MV Agusta bike as your screen name suggests?

      1. MVAgusta | Jul 09, 2006 01:34pm | #15

        Nope, I wish I did, the only bike I have now is a '77 R100RS that is sorta dead-in-the-water at the moment. I'm looking at my floor-switch right now and it looks like they didn't bother pulling the brass cover off before the last floor sanding. The antique store down the hill has one of the original bells from this house, it had a lableled ringer for each room. She wants $275 for it, I don't think I need it that much.

    2. BungalowJeff | Jul 10, 2006 06:22am | #25

      That's it. I have a brass one in the middle of my dining room floor....that's not a mistake, it's rustic

      Really? Interesting. Tell me more of what you know.

      1. MVAgusta | Jul 12, 2006 01:36am | #33

        That's about it, most of the houses around here pre-WWI had them, the town was more of a white-collar bedroom borough then. Other rooms had a wooden handle that hung from the ceiling or wall with a momentary pushbutton switch on the end. All of the wiring normally led down to a butler's pantry, to a box called an annunciator, which had latching relays inside.

          BillHartmann | Jul 19, 2006 12:39am | #38

          Most of them did not have latching relays, but probably some did.What they have is a "flag" that was lead in place with a latch. And one end of the latch was controlled by a solienod. When the solienod was powered it pulled alway one part of the latch allowing the flag to drop.Here are a couple of examples.http://mysite.verizon.net/dalderdi/phones/annunc.htmhttp://www.residentialarchitect.com/industry-news.asp?sectionID=152&articleID=313411&artnum=2http://www.rrmtf.org/cantigny/annunciator_in_butlers_pantry.htmand here is a call button that was on a cord.

          1. MVAgusta | Jul 19, 2006 12:43pm | #44

            I haven't seen the guts of one in awhile, but I'm pretty sure that you are correct about the solenoid vs. relay thing. If the store down the street is open today after work I'll get a picture of the one they have.

    Unscrew it, take another picture, post it, and we'll all know. Personally, I think it's an outlet for a light on the diningroom table, or a gas valve for the same before they had electric.

    1. BryanSayer | Jul 10, 2006 05:23am | #24

      Well, I'm out of town for a week, but I'll see if anything unscrews when I get back. The bottom side is covered up by air ducts, so I can't see it there. I've never thought about it unscrewing though.

          I've been out of town, but I'll try and check tonight if I can unscrew it. But I think the underside is hidden behind ductwork, so if it doesn't unscrew, I'll still know only what you know.

        2. BryanSayer | Jul 19, 2006 04:56am | #39

          Well, I tried to un-screw it with my adjustable pin wrench, and I couldn't budge it. Plus the under side is hidden by duct work.FWIW, the two outer most plus the one hole next to one of the outer most are just depressions, making me think they might be for alignment. The other holes go down to something.I want to re-do my air returns (line the joist bays) at some point, so I might have the ducts down. Then at least I'll be able to see the bottom, unless it doesn't go through the sub-floor.As for the phone jack, the location seems wrong. The middle of the dining room? But some sort of switch to call the butler or cook, that I can buy.

          1. DanH | Jul 19, 2006 05:00am | #40

            I don't think it unscrews with a pin wrench. I think you just remove the wood screws holding it down.

            Actually at dinner it is normally hidden and I don't even think about it. It's under the table then.Which gives me a new idea. Maybe in addition to the boarding house, the owner decided to pick up some extra $ doing seances. It was used for communicating with the dead.

    It looks like I can see a bit of wood through the center hole, making it unlikely that this is any sort of cap over a valve or some such. More likely it's a base or cleat for something to be attached.

    My first thought was a pole base of some sort, but more likely something like the butler call switch that was suggested. These would be secured to the dining room floor, under the dining table, where they could be reached by the toe of the master/mistress of the house.

    If it is indeed the base of an old switch there will likely be some old bell wire (or at least a hole where the wire used to be) coming up through the floor under the plate.
