That will effect the rate at which the cap dumps through L2 the Primary (low inductance few turn) in the working circuit and then through L1(high inductance) the motor coils.  I strongly feel a second coil should be added between the exit of the motor coil and the rotary gap disk to vary the inductance of the motor. This is shown in pat 568,178 .
Yes I agree, if you follow teslas patents he is making improvements on 568177. I use a 12v/120v transformer with the sides cut off to form an inductor (choke), then the sides can be moved to and from the inductor with brass screws to vary inductance quite accurately. I also use an AC commutated motor for L1 from a shop vac, it is rated at 12amps @ 120v. We should remember these AC commutated motors amp rating is based on the motor coils resistance, more resistance equals lower amp draw, so I wanted a high amp/low resistance motor which has its power varied through impulse duration/frequency not resistance---- resistance is bad.

@AC
good web link here for folks http://www.tpub.com/neets/book9/34a.htm
Just some basic ee stuff page 2 has a section on resonance and the curves showing the intersecting points of the inductive reactance and the capacitive reactance... There opposites yet when balance is achieved so is resonance. 8)

I see two sets of motor contacts, b-b and H-H. which is for the motor and what is the other set for? Does anyone have estimated values for the capacitors and inductors? time to experiment...

and an extra set in the front for switching too ..

For simplicity, can I use a standard small dc motor with an extended insulated shaft and on this shaft put the necessary contacts on it and on the shaft.

@quantum1024

I just posted that as refrence for folks so they could see the progression from 568177-->588178-->568179  helps when there in order and you can see the additions to the circuit.

I think you may want to look at exactly what is happening with the disk(rotary attachment with segmetnd pie insulation)in patent 568177. This has to be EXACT!!!   EG 0 and 180, 270 and 90  conductive strips have to be split into equal quadrants,  to start two conductive strips and two insulating sections will make for 2 on off cycles per rotation of the disk.


Here are the two things i see happening


1) The brushes  G on the left and K on the right complete the "Working primary circuit" every time the two brushes hit a "Conductive Strip on the disk". 

 
--This dumps the cap through the primary (L2) while at the same time short circuiting the motor. This "break" for the motor while the cap is dumping is what allows the current of high electromotive force is devolped for charging the capicator.

 2) Now the disk at the top has brushes G and K on the "Insulating sections" not shorted and the current of high electromotive force waiting in the motor coils can be discharged and accepted by the capacitor in the Working circuit.

Collaspe of an energy field into a circuit of negligible impedence produces a shockwave or energy that may reach astronomical amplitudes

More later -got to run

You bring an excellent point. Grumpy

How about this analogy

I pluck a guitar string that is not tightened or in tune say just kinda loose on the neck. The string moves when i touch it and thats it.

Now i tune the string up just by tightening it and then i pluck it.  This wonderful note comes out that i have tuned my string to and it resonates for a while until it dies out . 

How to tighten our string in the circuit is the real question and to what measure?

I offer the following information

frequency of oscillation on a string = (1/2L)(T/u)^(1/2) 

Where L is length, T is the tension in newtons, and u is the linear mass. Therefore we can see that as the tension of the string increases, so does the frequency of oscillation.

Now, knowing that vibratory systems are essentially correlated, what variables can we change in order to increase the frequency of oscillation for an LC circuit? And how do we measure these variables?

@armagdn03

Thanks i knew someone would get it. 

Well lets take tension to start  In an lc circuit  Voltage is proportional to tension i would say. (could be wrong )

Ok this  would seem to apply then, thanks!
 So Raise the static dc voltage to tighten up the string . Then Pluck it with the cap  ;D  Also if that holds true the tension is divided by the mass of the wire
therefore Raise the tension and lower the mass to get a good result.. a 1 pound guitar string would be a bitch to tighten and pluck for that matter but one of a few grams should be much easier to tighten.

@all

OK I removed my post because I finally found out what was happening and I am ashamed to say it, but you know, when you are open with everyone you are bound to make mistakes.

The problem was my meter battery was so damn low that it started playing tricks on me. I just changed the battery and the system battery now reads a steady 11.8 volts, which is better then were it was yesterday morning at 8.4, but not the 16 vdc I was reading an hour ago.

Geez, just junk it.

Now back to the EC.

Good observation, tension and voltage are analogous, however you will find that increasing voltage has no effect on the frequency at which an LC oscillates. keep up the good work!

Yes yes i know that raising the voltage wont affect the freq of the lc in the working circuit. Directly...  :)

But

Some motors run much faster at 50 volts than say 12.

Now  in pat 568177  if you raise your initial dc voltage not only are are we tightening the string in both the timing and working primary circuits but we are also making the motor spin faster. This Will effect the freq of the working circuit directly because the motor is spinning the disk which preforms the make and breaks faster, hence increase in freq/plucking of the string(process of cap discharging into circuit of low self induction/primary coil) .Also raising the freq of the working circuit could be acomplished by makings more cuts in the pie so to say the disk and the insulating sections.

Without the motor spinning the rotary gap -the relay way some are doing here can only be adjusted by the value of the cap and the inductance of the primary coil

                                                                                               Thanks for your input

I sat staring at this circuit for a few hours, it?s a brilliant circuit. Thank you for sharing!

If I am correct.
The choke and capacitor charges up and is disruptively discharged, (via the relay) into the primary coil of the transformer, (large current/voltage short duration into coil). The voltage is from what it was (the battery voltage) to a higher potential. On the secondary, down convert it, charge a capacitor/filter to higher then the impedance of the battery voltage. Battery now charges.  As long as the battery is charging at a higher voltage then what it was, it should maintain it?s self for a long long time. It?s basically like a self healing battery. It?s recycling while sitting at higher potentials. Nice!  ;D

Any time a battery sits at higher potentials (above the impedance of the battery) it is considered charging.

Motors spin faster at higher voltage, because current is induced by the electromotive force (voltage) hence raising the voltage raises the current flow through the motor, according to our power equation, Power = Current x voltage, an increase yields more wattage through the windings. an increase in either electromotive force or current will do this. (an increase in current without an increase in voltage is possible through a lowering of the resistance of the wire used)

Your analogy is good, but you applied the logic to the wrong part of the circuit. your string is your LC primary and cap, it is being plucked by the high inductance via circuit controller, if you spin the motor faster, you are essentially plucking your string with your finger faster, you are not tightening the string.

I see what you  saying now "your string is your LC primary and cap" I was considering my string just L2 or the primary coil. 

Also-
 "it is being plucked by the high inductance via circuit controller, if you spin the motor faster, you are essentially plucking your string with your finger faster, you are not tightening the string."

The reason i said to raise the voltage was because it would increase the speed of the motor as well as tighten the strings on the circuit its attached to already.  I figured hey two birds one stone.

Id say there are two discharge paths for current in this circuit that flip floped back and forth.

I see the way your saying now thats the charge cycle and the current goes through the motor coils into L2   and charges the cap.

Yet when the cap discharges, the current goes from the cap - back down L2 .   I don't know if this is right or wrong but it was the best sense i could make of it.

@localjoe
We should also remember that if you use an AC motor for L1 with a commutator disk that this device is self-regulating. As speed increases duty cycle or on time is lowered(speed decreases)---- as speed decreases the on time per segment is increased(speed increases). So L1 will always find its own optimum speed(frequency) depending on the current flow through it, the current flow depends on the load.We could say this circuit will vary its own frequency to match any load attached to it thus always operates at maximum efficiency.If we examine current AC systems we see loading or phase lead/lag will always load the generator which is fighting to correct this phase imbalance because it always operates at a fixed frequency. As well current AC variable frequency drives (VFD's) do not phase match which is just plain silly. I think it is just as important to understand how terribly inefficient our conventional electrical systems are in order to understand what needs to be done to correct them. How exactly does an AC motor load an AC generator? If you can answer this question then you can understand how tesla rectified this situation of loading the "generator" or the source and have the source add energy intermitently to a system which is in resonant oscillation with a load.

I think this might work... any suggestions?
I'm still stuck in the timing of this thing, i'm not sure at what the degree settings everything is supposed to be at.

the problem with what you have, is that your duty cycle is going to be a bit off, if you have an un-even ammount of copper space to non copper space, than the on cycle will be shorter than the off cycle, you want them to be rougly equal.
