I think I have it.

In 1895 a Mexican national temporarily residing in New York named Estanislao Caballero de los Olivos, in addressing torque and stability problems, designed a tandem rotor helicopter with wings.

I haven't found the patent, but it's for an elliptical heavier-than-air vertical takeoff flying machine granted to De los Olivos in New York.

The Challenge machine is obviously a somewhat re-designed, improved working model based on his 1895 patent...

The De los Olivos flying machine of 1904.
