The 1910 Jacobs Multiplane [also identified as the Jacobs-Emerson multiplane] was the creation of Henry William Jacobs of Atchison, Kansas. It had quadruplane wings and tail and two engines, each driving a propeller.
Jacobs used two improved air-cooled 35hp engines he invented, to replace the two original underpowered engines [Emersons?], with which the plane flew in 1910.
It was displayed on the New York Aero Exhibition 1912. Jacobs had formed with others the firm “Multiplane Limited” in Kansas to build the machine and eventually sell it to the market and a brochure of 16 pages was produced.
