I would agree.
I re-read the text and it still makes littles sense as someone who works with HV. I understand Tesla claims the "slotted hood" which I mistook for wires is supposedly to reduce breakout however obviously that's not true. Anyone who knows anything about HV knows the slots in "H" as shown are a likely point it would break out. We can also see the upper tube "B" connected to the top load seems to be connected to "H" and a wire from the top of the secondary "B" connected near "H". Yes, B' is connected to both the top of coil B and hood H. Anyone who knows anything about HV knows that a shape can be defined by smaller sections of a given shape. Take a look at the top load, as also discussed in the patent, the top load is a made of many smaller curved sections that define a toroidal shape. Also, one of those small sections on the top load is of a smaller radius than the rest to limit top load voltage and define the arc breakout location. The point I would make is that Tesla is obviously not telling the whole truth and most inventors don't to protect their intellectual property. The fact remains that anyone could build this patent as shown and to my knowledge the chances of it working as described are zero. I mean look at the ground connection "E", in the real magnifying transmitter it extended down some 120 feet into the ground then formed four separate conductors each near 320 feet in length. Yet here Tesla shows a convenient little box a few feet under the ground. Many have successfully replicated this three coil design. The third coil significantly improves efficiency. The patent drawing accurately portrays what is described and what is claimed, which is all that is necessary for a patent drawing. I see more than a few contradictions here and if someone told any credible Tesla coiler that part of the secondary/top load should be segmented or slotted to prevent eddy currents they would probably do a facepalm. It's just completely absurd because the current is generally always low and any surface not curved with sharp edges will always break out.
I see no contradictions. The top load being made of segmented sections is pretty standard and used daily in many fields, as using segments to define a shape is suitable for most HV applications. Same goes for the hood H, its segments define its shape, which is meant to have a radius larger than the B/B' connection point to prevent arc breakout at that connection. Regarding eddy current reduction, I do not know why you feel that is absurd. Eddy currents at the B/B' connection would present a parasitic load. I have studied Tesla for many years, he was indeed a genius, but too many people always try to read more into his work than what is actually there and refuse to accept the literal reading of his patents and notes. Sometimes a cigar is just a cigar... PW
