Hanon: Many thanks for your brilliant detective work.
I have a couple of questions.
In the UK copies of patents are held in Reference libraries up and down the country.
Is there a chance that there may be better copies in the Spanish reference library system?
In the UK there are also technical journals in the library system.
Is there a chance that there are old Spanish technical journals  dealing with Figuerea's inventions?

Hi,

You have to realize that we are talking about a time in the first years at the begining of the 20th century. As far as I know there are not more copies of this patents apart for the Official Historical Archive in the Patent Office.

In that time the patents were handwritten. For the first time I am publishing here the pictures taken from the patent 30378 (Figuera Generator) (year 1902). You can note the current state of the sheets.

Also I attach here the clipping from the Official Bulletin (Boletin Oficial de Propiedad Industrial, BOPI) with the formal  requirements that were not fulfilled by Figuera. Requirements: the objective of the patent is not clearly described, the scale in the drawing is missing, the ownership conditions and the novelty must be explicitly stated.

I hope you can enjoy this documents, at least at historical notes. I haven´t disclosed it till now because they are not technical documents.

For all the translations of the patents and other historical notes about Figuera please look into this site: http://www.alpoma.net/tecob/?page_id=8258

Has anyone built this exactly as drawn in the patent/s yet? No deviations.

Hallo Hanon,
thank you for the your dedication and for the help you are giving to the community.
I am working in the document, tying to make it understandable as much as I can.

BTW, I was expecting some more reaction to the artwork I uploaded, but...In order to give you something to think about it:

QuotePRINCIPIO DE LA INVENCIÓN
    Puesto que todos sabemos que los efectos que se manifiestan cuando un circuito cerrado se aproxima y se aleja de un centro magnético son los mismos que cuando, estando quieto e inmóvil este circuito, el campo magnético dentro del cual está colocado ganando y perdiendo en intensidad; y puesto que toda variación que por cualquiera causa, se produzca en el flujo que atraviese a un circuito es motivo de producción de corriente eléctrica
inducida, se pensó en la posibilidad de construir una máquina que funcionara,
no según el principio de movimiento, como lo hacen las actuales dinamos, sino según el principio de aumento y disminución, o sea de variación del poder del campo magnético, o de la corriente eléctrica que lo produce..

"...For the first time in the patent, he revealed the option used in his invention:
Creating induced current by changing the flux density using a variable excitation current.  as simple as that!, by doing that, you create or destroy the lines of flux making then to move closer or wider from each other's, this movement cut the coil winding!" => you need the best core materials to get the best electromagnet ...lamination with high permeability ...nothing new for us..

Then you have to find the CONVENIENT position for the collecting coil or the induced=> just look at PEAKS in the AC curve do you see how are the 2 B´s??

You will find more in the document, once is over.

Hi Doug1,
That is my intention (IMO, that should be the first step, and then playing with 3 coils). I am working on the commutator right now.

One thought I have been digesting is that the system , as difference with a transformer, has two magnetic fields. When both fields are equal (I1 = I2) both have the same intensity and they create a perfect link between them: all the lines of forces cross from one side to the other along the collecting coil. But when one field increases and the other decreases I think that this link is broken and the lines of force are not crossing the collecting coil anymore but they must go other site and thus they cut the winding. I posted an sketch in page 27 at the bottom. Maybe you want to go there to have a look.

It is just an idea trying to answer the question: Why did Figuera required two electromagnets, one at each side, with different magnetic fields instead of havinghat the same field?

I have found this video. Does someone know what it is explained? It seem a basic Figuera coil configuration

Welcome MNS!

Doug 1,

I am attempting to build the "old school" device with few changes. It is difficult to build a commutator
like a barrel like Mr Figuera, so I built one on a flat plane like the drawing shows. Since I was using
a 1800 RPM motor, I decided to increase the contacts to 32. Sounds simple enough but the amount of
connections and wires are confusing to say the least. I do not recommend this. If I don't get it sorted
out soon, I will build another with 16.
Anyway, I have four sets of transformers. I am having trouble right now getting the wiring for them and
the resistor to do what I wanted them to do. So far no good results. Also, I just found out that the
wiring diagram I had printed from the Internet wasn't correct and had the connections to the
transformers wrong.
I will keep everyone up to date it I have any success.

Thanks,

Shadow
