Weird Antique device Restoration from 1920s :: It Growls 

I guess no one out there knows what a Growler is for. It makes a certain kind of noise if armatures are shorted internally. I am sure better ways of checking are used now! Works good and great job by the way, for the restoration......

Super jest to odrestaurowany do sprawdzania wirników Pozdrawiam serdecznie. 👍👍👍👍

Interesting refurbishing project. When you did the ohm test of the actual coil, I was surprised you didn't test the coil to the case/core to see if it was isolated from them. But I guess it wasn't because it worked. Always a good idea to test for that since it could still read through the coil and be shorted to the core and/or case. Thumbs Up!

Used to use these to test starters and generators working on older cars.

Muito bom Brasil❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

It looks great and you did a wonderful job restoring it as well!!!! I enjoyed your video so I gave it a Thumbs Up

the hammered paint was perfect

No matter if this thing has any purpose but please before using it the next time get a three wire cable and connect the housing to the PE.

An interesting device, however, its construction and design is much younger than the year 1920. And that braid bolted to the cabinet had a purpose. It was used to ground the metal packaging and thus to protect the operator from electric shock.

I seen one of these in use back in the 1970s.

Possibly the device is to demagnetize the armature. If rotated slowly and removed slowly all the magnetization would be erased. - The DC resistance of any coil looks very low for something that will be plugged into the mains. Impedance is the term used for AC resistance. Most impedance testers are for audio or RF frequencies. I think that, if plugged into 120 volts, it drew a current of 2 amps, you could say the impedance is 60 ohms at 60 Hz

It was used to check A generator armature for short

Nice😊

Haven’t seen one of those in a while. It’s a small one though.

If it’s from the 1920’s Philips head screws wheren’t around so those screws where added much later. I thought they where an eyesore from the get go and was surprised to see you restore them. I think they should gave bern tossed and replaced with more appropriate ones. Apart from that, good job

for testing Armature

😀👆 nao sei que estrumento e esse ,e pra que serve 🤔👆 mas seja la o que for esta novo denovo 😀👍

restaurado dispositivo 😉

👏🥃😋👏🥃👍👏🥃👍👏🥃👍👏🥃👍👏🥃

ممكن شرح أكتر .كيف صنع وشكرن

Painting could be better...

Well, that was a waste of time.

What the hell is that thing?
