Shaft Rotary

Shaft Rotary
Shaft Rotary
What is the patent number, for the rotary, three-phase, mechanical, power inverter, issued in 1962 ?

I am calling this device a rotary inverter, because it is a mechanical switch, comprised of three slip rings, and a commutator, mounted on a common shaft. It is not an integrated, or discreet, motor-generator. The output is square-wave.

I know the patent exists. I once examined, a paper copy of the patent. However, I can't seem to find it online.

Here are the two i found, hope this helps.
