Watthour Meter Collectors?

Re: Watthour meter collectors?

I've got a few cool old ones, but not enough to be considered a collector. Not sure what to do with them other than make lamps out of them.

I have a couple. I use them to measure how much power certain things take, like a refrigerator or whatnot...

I like those big style meters. Found one of the big reed type meters at a flea market for $5, and later sold it to a friend who admired it - I have been a bit regretful since.

Re: Watthour meter collectors?

After a prolonged period of inactivity, I decided to dust off my collection and when looking for a good parts meter, I instead found a new addition to my collection.

A late 1941 GE I-30-S (probably made between December 8 and 31 - note the GRAY paint used instead of the normal aluminum paint)

A bit more searching turned up a GE I-16 socket conversion, another model I'd tried to find in the past.

My current specialty (and going forward) will be these early socket types with metal baseplates. I currently have almost all the models (and major variants thereof) from this era, but have a few I'm still looking for:

Duncan MF-S, 50 amperes 240V
Duncan MF-S, S/N in the 3,3xx,xxx range and gray steel inner frame
Duncan MG-S (if such a critter exists)
GE I-20-S, S/N below 17,194,000
Sangamo HC, socket conversion
Roller-Smith S3

I have seen quite a few of that vintage or before still installed and working around here. Some of them did not get replaced in the smart meter project, I assume because the sockets and/or jaws did not fit.

Interesting: I see these at the "FLEA" markets from time to time, and they stay on the tables. Recently I found some larger volt meters, but always leave the watthour meters(who collects them anyway :crazy: ). Hmmm :idea: just might have to start a new "small" collection :shrug: .

Ron: Interesting set of meters you have there. Certainly would have liked to own one of those massive General Electric CS switchboard meters at one time, but the size and weight have always deterred me.

That clock is a "contact-making clock". There are a set of contacts inside that close for a few seconds every 15, 30, or 60 minutes to reset a recording demand meter.

Seeing that Sangamo D-5 meter positioned like that makes me nervous - unless the mercury in it has already been drained?
 
Re: Watthour meter collectors?

ND I don't see any mercury rolling around inside. I didn't know they had mercury in them. What did the mercury do in the meter? Ron

Ron: The mercury is contained in the chamber just beneath the brake disk that you see. All Sangamo DC meters operate on the mercury-motor principle (so that chamber contains at least a couple ounces' worth of mercury).

My suggestion would be just not to try and take it apart and maybe build some kind of stand to keep it upright as much as possible, although the disk shaft has baffles arranged at the point where it enters the mercury chamber to keep it from dribbling out if inverted.

Re: Watthour meter collectors?

Here's a gem of an unmolested meter that I found today at River Market Antiques in downtown Kansas City, Missouri. I have no idea what it is, but the seller named it as a 1913 Vintage Westinghouse Watt-hour Meter. He had a price of $65.00 on it, but I bid $50.00 and got it. Neat thing about this antique shop, they will take your offer and call the dealer to see if it is ok. Normally, an antique shop will cut 10%, but beyond that, you are out of luck.

Anyway, it looked good to me. Westinghouse Time Element Overload Relay, Type CO. What's that?

Re: Watthour meter collectors?

As I understand it, it was used with breakers to allow a circuit to run above its rated capacity for a certain amount of time before throwing the breaker - likely used on certain circuits to handle start-up surges from large motors while still tripping out on sustained overloads.

Nice meters - especially that Ft. Wayne. Those are almost as rare as hen's teeth these days.

Re: Watthour meter collectors?

My latest acquisition - and which looks like it may be a project in itself.

It's a GE I-20-S, but a second generation unit. It's a bit on the pitiful side (looks like it had water in it!), but hopefully a good cleaning and a new cover will improve the appearance some.

Still looking for one with the full steel baseplate. I've got an old catalog cut of that version somewhere, and will post when I find it.

The same meter as the previous picture, after a quick cleanup and a new cover. It definitely had some water buildup in it, likely after power was cut (no sign of arcing anywhere inside).
Still needs some more cleaning - but at least the worst crud is cleaned out.

Definitely not a long-term addition to my collection due to condition, but I couldn't pass it up at the price, and if it went anywhere else, I'm sure the buyer would have instant remorse, then a refund, and off to the landfill.

At least now it's safe and possible future trading stock.
