This is the Quadraplane built and flown by Matthew B. Sellers in somewhat different versions during 1908 and 1913. The machine can be pinned down by its quadraplane construction and typical connection between the wings (single rods). Also typical was the three wheel undercarriage (two in the front and one in the back) and the tractor propeller. The pilot (Sellers) sat low in the machine, probably on the floor of the 'cage'.
You will not believe it but the machine flew quite a lot and I remember having seen a picture of the machine in flight.
Engines used were very low in horse power. Used was a Kemp G-2 two-cylinder engine of 16 hp and an even lower 8hp Dutheil-Chalmers (!).
There is a replica built of this machine, which can be seen in the Aviation Museum of Kentucky. Looks like this
