1920s Rare Battery Charger [Restoration]

Тәжірибелік нұсқаулар және стиль

In this tool restoration I focus on a 900-Sterling Rectifier made by The Sterling MFG. Co. of Cleveland, Ohio. The rectifier was most likely used as a battery charger for radios and cars in the 1920s. From my research, I do no think this exact model is a common tool as the pricing suggests it was around 5% the cost of a Model T in 1922. I believe this is a vibratory reed half-wave rectifier, but I am not 100% sure. This technology was used before vacuum tube diodes became popular.
The actually restoration was much more involved than I thought it would be and I was concerned that I would not be able to get this to work once back together. Electrical wiring is not my area of expertise, but a bunch of research helped. I was not able to find an exact patent, but this one was close: patents.google.com/patent/US1...
I chose to replacing the nickel-plating on some of the brass parts, but not all. I had to remake some bakelite pieces, but was able to revive others in plastic restorer cream. I also chose not to do a clear coat on this tool as the original paint seemed to not be that glossy originally. I would have also liked to rewire the main coil, but I just do not feel comfortable yet tackling that. I really do want to have a try at rewinding an electric motor, but I don't want to practice on something so uncommon.
I was VERY surprised that this worked after I wired it back together. It took me about 5 hours of wiring to make sure this was put back together in the exact right way.
Hopefully I can pass this along to someone that can exactly explain how it works!

    Based on only watching half the video, what I see is a simple electromagnet chops the 6v AC wave pulse coming from the transform down effectively creating crude DC current, the sense line to the meter probably comes right off the larger coil which creates the pulsing magnetic force used to generate the DC current. The buzzing and adjuster are probably there to allow you to control the pulse width of current being sent down the charge lines. Looks really similar to half of an old school Lucus "regulator" for old bikes. But I'm not an EE so I could be way wrong here.

    Shain Andrews quite many 20s-50s radios in the US had no transformer so if you plug it the wrong way you had a live chassis. Originally they came with polarized plug that can't be flipped but since those were breaking and sockets of that type became rare people were replacing them with common NEMA plugs. Plug it... ouch, I need to flip the plug, top mark on the plug and that's it. Here most radios had transformers since 30s because 220+ volts are more likely to kill you. But also... 19th-early 20th century industrial equipment had huge open moving parts and yet people didn't get hurt that often because it was a common sense that you shouldn't get your nose near a huge flywheel at 1200rpm. Just like washing machine manuals didn't have warning about washing animals because everyone understood that an animal will get drown in a washing machine.

    Those two round coils are there to provide a magnetic reference for the switching element. (The patent has a permanent magnet instead.) The small coil around the switching element causes the element to move according to the magnetic reference. The big coil is just a step-down transformer. The design is very ingenious. It uses the voltage from the battery to make sure the magnetic reference is biased the correct way. So you can hook up the battery either way and it will still charge it. (The advertisement says that you can connect it “without regard to which is positive or negative.”) The patent doesn't have that feature since it has a permanent magnet instead. This also means that you can't charge a fully dead battery without risk of charging it backwards. This is the reason the ammeter goes both directions. If you hook it up one way it swings to the right, the other way it swings to the left. Since you grounded the case, you may need to be wary of using it on a battery that is also connected to ground. Because it may be possible that one of the charge cables is connected to the case. The patent also has two half-wave rectifiers, but the one you have only has one. This was probably to make it easier to adjust, as you only have one adjustment instead of two. Also with two there is the possibility to short it out. Don't rewire the main core unless there is actual damage. It would be difficult to get as nice of a wind without a lot of effort.

    @@railgap It is a magnetic-mechanical design. Both of which are difficult to describe without visual aids. Also I was going for a short description that gives the gist of how it functions to nontechnical people. For technical people the patent, and advertisement should be enough to figure it out. Which means they should have figured it out before reading my comment. Someone who watches a channel named Hand Tool Rescue probably isn't going to understand a technical description. So I probably shouldn't say that the two small round coils combined with the coil around the switching element creates a magnetically selective half wave rectifier. Since the two magnetic reference coils are initially energized by the battery, the selection of which half of the waveform is determined by which way the battery was connected. This is different to the patent which has a permanent magnet, so it was not ambivalent to the direction of current. Oh by the way, I am entirely self taught in the areas of electronics, magnetism, mechanisms, and programming; I have had very little interactions with people knowledgeable enough in those areas to describe things in that manner. So instead I tend to describe things in a more newbie understandable fashion. Well there is one exception. I regularly interact with newbie and expert programmers, so I know just how big a divide there can be between the two groups. Trying to describe something for both audiences simultaneously is a frustrating experience.

    Thank you again it is always a pleasure to watch you work. Im 60 years old and have personaly watched the rapid evolution of tools and technology. The craftsmanship and design and skill and beauty of so many products of the past were discarded with little thought of their value to history. And in some cases their superior quality of materials and design. In my own case I found it impossible to buy a simple toaster that had a life expectancy of more than a few months. I began to look for the old American made stuff and found that yard sales and estate sales have a few. And many other things that are so much better made than the new stuff. We need to revive the manufactor of these older bullet proof products. Buy 10, twenty dollars toasters or 1, 100 or so toaster with nearly 100 times the life expectency. Not only that the beauty of a much better quality product. Polished stainless or cast aluminum with real wood acsents. Many young people have never even seen or used the quality products of the past. Every thing today is disposable and its pileing up in the form of plastic waste. We can and need to get away from our dependence on chinese made junk. Combining the best technologys of old and new we can improve on what our Grandfathers lovingly crafted. And create manufactureing jobs and small foundrys. Sure everything can be cnc machined out of a block of whatever or 3d printed but its just not the same.

    I wondered exactly the same thing! As soon as I saw the carbon block, that's when I realized, that this uses a synchronous vibrating contact as a "mechanical rectifier". Noisy, but effective. I like the idea of the thumb screw, to be able to adjust it. It might even serve as a Silicon Controlled Rectifier, allowing you to adjust the charge current, although, most would set for maximum amperage. It's a very clever way to convert AC into DC to charge a battery, without any kind of thermionic or solid state rectification.

    Oh, some memories! My mother's older brother described how something like this charger was used to charge the batteries used in the radio sometime in mid 1920's. Somebody in the same village had the charger, so the batteries were carried there every few days for charging. The vibrator based inverters were used still in late 1940's and indeed even early 1950's in the early car radios to convert the 6 V car battery up to somewhere between 100 and 250 V needed by the tube amplifiers anodes. Transistors came a bit later, along with the car batteries changing to 12 V. But the big memory is from the high voltage laboratory of the university. One of the lab demonstrations (yes, we students were not trusted to run that by ourselves) was how a synchronized mechanical rectifier worked. There was a 3 or 4 ft diameter wheel with some wires between copper contacts at the rim. A synchronous motor was rotating the disk -- once we it started. That start required several attempts of jerking it and immediately engaging the motor power switch. If the jerk was not good enough, the motor did not "catch in". Once the motor was spinning, the high voltage AC was turned on and the copper contacts started sparking and obviously generating lots of ozone. But the mechanical rectification did produce growing DC charge to the big metal spheres, until at some 30 to 40 kilovolts there was the great flash and bang from the spheres. I do recall that we measured the gap and used some graph to report the achieved spark voltage. As a side note, at another lab soon after I saw how really high voltage resistors were constructed of long plastic (acrylic) pipes filled with with distilled water. They worked as current limiters at 200 to 500 kilovolts.

    That's some awesome vintage equipment! Love it! I would recommend rewinding both coil as it looks like one of the coil insulation was damage. This should be simple to do. Count the number of turn on each coil and redo the exact same with new wire of same gauge. Awesome restoration! Cheers!

    I agree that it would be interesting. It would seem that it would be necessary, to make sure the resonance of the vibrator is right at line frequency, so the contact is made right at the crest of the AC wave form. With a new carbon block, it would be heavier, and would tend to lag in phase just a little. As it lightens up from normal consumption, the resonant frequency would rise, which would tend to make contact before the crest. a dual trace oscilloscope would tell the tale!

    Its 120v the risk of serious injuries in the event of malfunction is pretty low other then you get a hell of a shock especially if it's the hot wire not the neutral wire. Small appliances today (usually) have at least two layers of insulation between the conductive components of the device and any part of the device you can touch. To achieve this cheaply, often the outer casing of these devices are made entirely of plastic or some other non-conductive material back, in the days when law suits were rare they didn't worry about this at all. The grounded plug outlet wasn't even common until the 1960s and today it's only seen on items that are either used in damp areas or some times have relatively High amperage requirements.
