Well I would not qualify the machine as 'monstrous', this is possibly looking at this 1911-1912 machine with the eyes and knowledge of 2011.
The Jacobs Multiplane [also identified as the Jacobs-Emerson multiplane] was published in quite a lot of USA aviation magazines of the time (and the New York Times] as it was exposited on the New York Aero Exhibition 1912.
H.W.Jacobs had formed with others the firm Multiplane Limited in Kansas to build the machine and eventually sell it to the market.
The evidence for this market approach is in a brochure of 16 pages which has miraculously survived. It is sold for $750 at
The MULTIPLANE (Trade Mark).
Remarkable in the machine design is that each of the two propellers were driven by a separate engine.
You may also take information on the construction by the elaborate US Patent 1,245,724 Aeroplane filed on June 27, 1911 and patented on November 6, 1917 (!).
If you are in the market for more research on Jacobs and his Multiplane Corp, do have a look in the Airplane directory of the NASM
SIRIS - Smithsonian Institution Research Information System
The NASM references three separate objects:
- Jacobs brothers Multiplane (1911)
Jacobs brothers Multiplane (1910)
