Carlos Benitez patent No.17811 circuit drawing self runner

[Paul-R]

When I do a search for Patent 17811 it says No Such Patent.

                                                                                                                                                                              .

It seems tobe an old numbering system.

As a.king21 says in post 5, here it is:

You harness them both at the same time.

Without a tap in the middle part of the coil, secondary with diodes like that, behaves like a plain metal acting as a capacitor plate for dielectric induction only. No current flows inside there.

ps. By the way. The numbers as those are indicated in my drawing, are the exact numbers as those are being described in the patent. Just for making it simpler in understanding .

Hi guys.  I am making a commutator, like the one in Benitez first patent, and it has been fun, it have been a very rewarding project until now when i am close to being done with it.
I have finished about 90% of it, but i can't figure out how I should attach the copper sheet metal that i have cut out.
First i was thinking about fastening them with screws, but i don't think that's a good idea.
I am using screws for brushes, so I'm afraid that they will get hooked on the copper if it doesn't lay flush with the wooden rod.

Do anyone have any thoughts they would like to share?

Nice project
Engraving wood perhaps? Sticking it with epoxy? I would use a mechanical rpm multiplier if it is to be used by hand. With little effort you can build a great experimental rotary switch. Keep it up

Hi Jeg,
"Without a tap in the middle part of the coil,"
I don't see a center tap in your drawing. I have not tried this but ,this is similar to what my circuit is doing (I think).

Antimony, Instead of screws for brushes try using old guitar strings that's what I use.
