Brass what's it......... Maybe electrical?

Almost 3" long with the wire. End has letters and numbers on end ...... LM CO A-N 50
I was thinking 50 might be year?

Could be part of a fuse "50A" for 50 amps

Re: Brass what's it......... Maybe electrical?

Looking at the pic with the letters on it leads me to think it says "L.M. CO." on the top side and "50 A-N" at the bottom portion.

Back in the 19 teens a company called Langson Manufacturing Co. started up and made all sort of stuff it seems. They also refer to themselves as LMCO...

Nothing yet on the item you have, but it could be something of theirs. They also had some military applications too from what I can see.

unsure of age, it looks like a fuse assembly from a older high voltage power supply...possibly lockheed martin

This is what I was looking at. The center part is usually cardboard.

Time Delay Fuse, Style HVAC, Type Current Limiting, HAC-R, 50 Amp Rating, Volts 250 VAC, Dia 13/16 In, Length 3 In, Blade Design Ferrule -this was the description, the dimensions might help, but they come in many sizes.

I dont think thats it. Thats commonly called a cartridge fuse.

Second thought it does look like it on the bottom. I never busted one open.

Ask and ye shall receive!

Since there are a LOT of items found that folks label as a fuse (me included at times) I thought this dissection would be a good thing to do.

I asked one of my techs to get a a 50 amp slow blow about the length of what was in the picture. He brought back several examples of fuses so we could make a comparison of them all to the object originally found. Below are what we came up with.

Sorry for the crappy pics (I usually do MUCH better), but an Iphone was all I had to work with.

Crap, I hit send instead of preview... :P

I talked with 2 of our electricians (one is an EE the other is our on site master) out here and they both think that the original find it not a fuse for a couple of reasons:

1. The hole in the bottom could assist in an arcing event prior to the fuse blowing. They have seen landing dimples before, but never a hole.

2. The long run of brass going up to the wire is something they have never seen and the stranded wire would not be used for a fuse due to variables in resistance over time. They stated that solid metal would need to be used for an application such as that.

BUT, they both concurred that ANYTHING is possible with old stuff so the final conclusion here, it could be, but not likely.

I'm curious - can you move the wire by pulling on the end of it? (I'm thinking like pulling on a choke cable).

Nope it is solid!

I agree but I cant believe there are no hits on this combination.
I doubt it but could it be 750 A-N?

A partial part of a plane or some other kind of military hardware/weapon perhaps?

Where did you find it?

 

[Bigcypresshunter]

Re: Brass what's it......... Maybe electrical?

Nice research BTW. Could it be this center part of a larger fuse?

Good point! I'll look on Monday whn I get back to work and let you know.

Re: Brass what's it......... Maybe electrical?

maybe brushes with the spring eroded away from an

old electric motor or generator?

Re: Brass what's it......... Maybe electrical?

It is an electrical distribution fuse. It is a "blown fuse". They fit in a barrel made of fiberglass, and the fuse is spring loaded, so that when the fuse blows the tube will open and then hang down, showing that the circuit is open. The 50 an is a size/time reference number.
I put a lot of these in during storms when I worked for the power company.


The picture is of "A" phase fuse blown and open. See it hanging down? They sound like a shot gun when the fuse blows.

Here is a picture of a new one.
