It may be work, it may be play, it may be near, it may be away. So here is the challenge - to shoot and post one photograph a day on this site. These photographs are a kind of diary of things I find interesting. I am also thinking that there will be days when I am unable to shoot, so on those infrequent occasions, I will post a photograph done on another day, but one that still feels important to me. - Ken Spencer

The Thermostat
This is an amazing device. It is the old furnace thermostat which has been on the dining room wall since we bought the house back in 1971. I am assuming it was installed with the oil burner. My guess is that all happened in the 1950's or so. This was manufactured by the White-Rogers Company, which fortunately is still in business. Here is what is amazing - this is an entirely mechanical device that works by having a "bimetal coil" which coils or un-coils depending on the temperature, and that in turn opens or closes a single contact, which then tells the furnace to start or to stop. This is a mechanical device which has functioned with no problems, ever, for at least SIXTY years! This mechanical wonder was replaced with a modern digital one, when we had the new gas furnace installed last month. Somehow it seems a shame to replace something that has served us so faithfully for all these years.

ReplyDeleteNew is not necessarily better... Thanks for the explanation. bsk
Sounds like you're channeling my dad. Resist the urge to keep it.

Polly! You are SO funny! You also are reading my mind! I was telling myself today that if I had really good photographs of it, I wouldn't need to keep it!
