Stubblefield coils (bifilar) and speculations

[Pardon]

Thanks Jeanna for the brochure information.

did anyone catch the part about the telegraph setup making the make/break connections.

I thought i would make a change to my coil and ended up with a short. so no more coil i tried to save it but it's now in pieces. my next coil i hope will be as good as this one was.

i need more than 1 coil for my next set of tests. i would like to have at least 3 coils. I wanted to test them in series. but i just cant think of the best way to wire the coils since they have 4 connections.
I was able to use 4 water cells in series connected to my coil and had the coil up to 1.46 vdc 2.4 vac and .24 ma

my coil tested at .58 vdc .6 vac and 6.75 ma before using the wet cells so i can't or don't know why the ma's went down to where they tested at in a series configuration.

You're welcome, and also thanks to RL for taking the time to scan and email it to me!

I think the reed switch mimics the telegraph thing, doesn't it?

I am so unschooled in this, I haven't ever seen a telegraph set up nor touched one, so I am not sure.

good question.

i would like to have at least 3 coils. I wanted to test them in series. but i just cant think of the best way to wire the coils since they have 4 connections.

Good plan.

They do work in series. They lose a little bit, which is probably really interesting but I don't know what.

With 3 in series like so: 

meter-cu | fe-next cell-cu |  fe-next cell-cu | fe-meter

They add up; but, there is a loss of about 0.1volt.  So .54 +.35 + .25 = 1.04v instead of 1.14v...

I suppose since the cu and fe wires aren't actually connected except by magnetic field, this is very productive....

How curious!

Meters do odd things to our coils, but then the coils do odd things on their own.

How did you connect the coil?  I mean which wires did you choose?

Good work, Pardon

thank you for telling us all this. It really helps,

[Pardon]

here was my set up for series

house ground to stubb coil bolt to water cell minus rod also to the meter. plus rod to next water cell minus. plus side to minus of next water cell. next cell plus rod to either the 5 or 6 of the stubb coil plus the meter connection.

i believe that was the setup i used to get the voltage i measured.

also i looked at patent no. 887357 again but this time i copied the battery circuit to my own drawing, it dawned on me at that time the stubbs circuit looks like a APM circuit only stubbs used no caps. but he used very long lenghts of antenna wire. the wire being very long would charge the battery maybe up several thousand volts i think. and if so the secondary would have to be made to adjust the voltage level you would want to use.

this is just my opinion

@ storre:

DO NOT ADD SALT!!!!  This has been tested by me and.....it did nothing but almost destroy my first cell.  I added just a pinch to the water in my sink and everything went to 0 and stayed there for many days.  Some folks gave me helpful suggestions like putting the cell in hot water to dissolve the salt, which I did.  It took many baths in very hot water and several days for it to come back.  It never fully recovered but, it works pretty decent now.

I have added a little distilled white vinegar as suggested by someone else and the mA's went through the roof.  At least for me anyway.  I was able to get it up from 20 mA to about 80 with a little vinegar.  This result is short lived however, it goes away after about 3 days outside in the ground.

Just wanted to pass this on.  Hope it helps.

Hi Bill!

Any good electrolyte should increase the mA. I have some ionic water that I'm anxious to try once I get a couple of parts I'm waiting on. Lemon juice should work also. The fact that your batter died after 3 days is exactly what I would expect to happen. This bifilar battery without the make/break circuit is just a normal battery so will gradually discharge. The fast opening and closing of the circuit seems to charge and discharge the battery 100s of times per second or at whatever frequency the switching is happening. That I think depends on the length of wire used in the primary. Longer wire might (my guess) cause the magnet field to build more slowly so the bouncing back and forth of the ions (due to the opening and closing of the reed switch) and this would determine the Hz of the primary. The secondary is just a convenient way to tap this oscillating power without interfering with the operation of the primary.

So we need to concentrate on making a strong primary but have to incorporate the reed switch so that it pulses on and off. The magnetic field needs to turn on and off. Maybe the frequency is important for the action not to decay but I'm guessing there. He doesn't mention anything about that in the patent and conversely he says the primary can be of any size. Bigger battery = higher mA so we have to reach a threshold to be able to open the NC reed switch and start the oscillating.

I did this last night with a home made reed switch and was able to get the action going. It resulted in very quick sparking action but I didn't put on a secondary to measure the Hz. Reed switches will be much easier to deal with though.

Storre,

Would you be willing to give instructions for making this homemade reed switch.

I have some tiny NO switches that I bought.

So, as YOU pointed out I cannot use them for this battery, but I tested them all for magfield change. All were unaffected by the mag field of my coils.

They were all effected by a store bought ferrous magnet.

They all showed no circuit resistance (no ohms, as in infinite) while open but whan the magnet came close the resistance went to show the ohms showing that the switch had closed.

But not with my NS coil orimary. even touching the base didn't close the switch. I know it is magnetic, but not enough for these tiny switches.

I will try with another cpil, but I would like to know how you went about making your home made one. What metal and what you used to hold it and a pic as in photograph of the homemade switch  , if possible.

Thank you,

jeanna
