LS:
had to re-think what I was trying to say, but in the patent NBS says the connect 5 & 6 however do note(or correct me if I am wrong)that he is referring to Figure 4 which has the secondary(outside) coil.

"It will therefore be seen that the construction of the battery illustrated in Fig. 4 is practically a self-generating induction-coil, and it can be used for every purpose that a coil of this character is used, for as long as the coil-body 4 is wet or damp with moisture electric currents will be produced in the manner described. It will also be obvious that by reason of the magnetic inductive properties of the coil-body 4 the core-piece 1 will necessarily be magnetized while a current is going through the body 4, so that the battery may be used as a self-generating electromagnet, if so desired, it being observed that to secure this result is simply required connecting the extended terminals of the wires 5 and 6 together after wetting or dampening the coil-body."

So, from the way it sounds to me, you would need to try this experiment on 5&6 after you construct your core with the secondary coil around it.

Hello LaserSaber!

Very nice demonstration in video http://www.youtube.com/watch?v=lcjxA7bYUp0.


What happens if you

connect outer copper to inner iron (the copper wire and the iron wire in series in the same turning sense)

and then messure (voltage, amperage and magnetic effect) on outer iron and inner copper ?


For completeness sake one could

connect outer copper to outer iron (the copper wire and the iron wire in series in counter turning sense)

and then messure (voltage, amperage and magnetic effect) on inner iron and inner copper ?


You propably thought of this yourself and it did not cause anything interesting to happen?

Greetings,

Conrad

To Wintermuteai1 and LaserSaber!

Having read hundreds of old patents and also newer patents about "wonderful things" I observed that many inventors do not describe crucial elements, materials and even important electrical connections in their patents. This is of course misguided, because exactly these important features will not be protected by the patent. It is the old "I want to become rich and therefore I keep the real secrets to myself" that leads people to do this little tricks, and specially laymen and lone inventors are prone to it.

Therefore it is best to replicate the "wonderful thing" as LaserSaber is doing so nicely and to experiment in order to find out additional or not disclosed effects.

It is of course clear that one needs an even number of winding layers in order to come out with the wire ends at the same side where the beginning ends start. But this might be the sloppy drawing in patent US600457 and not an intentional omission.

I like the idea of LaserSaber to use reed switches and a little rotor (with permanent magnets) to switch the coil (or the copper and the iron coil) which might in the end induce a higher voltage and current in a secondary coil (made out of enamelled copper magnet winding wire).

One could also do the switching with a transistor in a joule thief style circuit, but the rotor and the reed switch will work with very low voltages and very low currents (much lower voltage than with a transistor). Although it will be difficult to get a stable switching frequency with the rotor and the switching frequency might have to be increased by using more magnets on a bigger rotor. But the massive inductance of this big and heavy coil might just ask for a rather low frequency (in the hundreds of Hertz), which has implications for the secondary.

So, LaserSaber is on the right track and it is good to find out much more about the magnetic properties of the coil before going to a secondary which might have to be optimised in a certain direction (e.g. low frequency).

I have since some time planed to go on a trip over Easter, therefore my Stubblefield coil replication has to wait a few weeks. I am also just building an orbo replication which is in the final stages. Orbo (toroids as magnet shields) is an interesting motor concept, but not over unity as far as I can see.

The work of LaserSaber has definitely hooked me on Stubblefield coils.

Greetings, Conrad

Reed switch and rotor with magnets on a Stubblefield coil:

I just looked into reed switches  http://www.farnell.com/datasheets/317181.pdf 

Typical operate time incl. bounce is 0.5 ms, release time 0.1 ms.

With a typical reed switch and a rotor with magnets, the Stubblefield coil can be switched with a frequency of up to about 1000 Hertz ( 1KHz ).

Let's hope that this is a good range for driving a secondary.

Soft iron core of a Stubblefield coil:

The iron wire used for winding the coil could also be used to build a core by packing e.g. 15 or 20 rods (wire cut according to the intended height of the coil) together to form a thick rod with about 10 mm diameter.

Or one could stack flat cable ferrites  http://www.farnell.com/datasheets/81244.pdf  to form a rod like structure (by gluing the flat ferrites together, overlapping).

Conrad
