It could be a Bancroft (Basil or Louis) Bancroft Airplane Co, E Hartford CT.)
Extract from Aerofile Site
"1917-18 = 1pOB; 50-60hp Anzani (uncertain). Wood and fabric design described as being influenced by Caudron G.3. Employing a two-control (rudder and elevator) system adapted from 1910 Voisin system, it had a small podlike fuselage with twin booms, fabric covered for lateral stability, and two-bay wings that were fairly standard biplane style but minus ailerons. Reportedly underwent Army evaluation, likely as a trainer, but was rejected and stored away in a barn. Discovered c.1961 and was undergoing restoration when it was destroyed in a shop fire."

"So, what in the world was this Bancroft airplane? We
learned that it was designed and built by Louis Frederick
Bancroft, in 1917. Bancroft was born on October 12,
1874, in Windsor Locks; Connecticut, and educated in
the East Windsor school system. He had served in the
Spanish-American War and later opened a realty
company in Hartford. He was for a time a tobacco
farmer and did other odd jobs before he became
interested in airplanes and their design. As it turned out,
only that one airplane was ever built, which was to have
been powered by an Anzani radial, air-cooled engine.
The ship had a very unique design, but was basically a
biplane, with a wingspan of 28'4". The most noticeable
feature of the design was the conventional tail supported
by the patented and canted surface (fabric covered) tail
booms. They were to provide the lateral control, as
stated in his patent. Bancroft did not wish to infringe on
the Wright Brother's wing-warping patent."
Impossible to find one photo of that strange plane on the web !
