Here is the Wilford Heli-Gyro, described as "a streamlined version of the Focke Helicopter" (Fw 61)... to which Wilford answered that “[w]e are not trying to copy Mr. Focke’s word in any way, but I am just interested in seeing that rigid feathering blades are used in the helicopter field as well in the gyro field.”

Please remember that all the Wilford designs were done on behalf of the Pennsylvania Aircraft Syndicate (there never was a Wilford company).

Here is another of his "convertiplane" designs based on an aircraft evocative of the Bell Airacobra (this was in the famous "German" helicopter files...):

Hi Skyblazer,


maybe the same concept but with a little different in configuration.

and if someone can make them clearer ?.

There's only so much that can be *easily* done with these since there is so much contrast in them due to being folded like that. Especially when you work with the low-rez preview images rather than the full-rez versions (the "airliner" blueprint, for example, is 13,014X 10,000 pixels and 10.96 megabytes, *far* larger than the dinky 730X560 pixel version you posted). The best thing for them is likely to re-draft them. A tiny crop from the airliner:

This looks a LOT like the CW-19/23 series.

Yes, this concept was based on the Curtiss-Wright 19-R. However, this was not, strictly-speaking, an E. Burke Wilford design.

As the original caption makes clear, another engineer - one Elliot Doland Elliott Daland - was studying the placement of an 11.60 m diameter Wilford 'wing' on the 19-R airframe.

Umm, yeah. As noted directly above, that was an Elliot Doland Elliott Daland concept incorporating E. Burke Wilford's rotor design onto the Curtiss-Wright 19-R airframe.

That would be Elliott Daland, who was a prominent engineer going way back with early rotary-wing firms such as: Kellett, Platt-LePage, and Piasecki Helicopter.

Well that certainly explains why I couldn't track down any further details about 'Elliot Doland' :D Cheers!
 
Also these patents.
