Thomas Brothers Nacelle Pusher

The 1913 Thomas Bros. three-seat nacelle pusher biplane was powered by a 90 hp Austro-Daimler engine. Distinctive are the equal span wings, the nacelle mounted on the wing, the sturdy four-wheel inclusive skids undercarriage and the double rudder. This machine must not be confused with a quite similar single seater nacelle pusher also built by Thomas in 1913. This single seater differed in having unequal span wings and the nacelle that was fitted between the wings.

Span: 37′
Length: 27′

Thomas Brothers TA / TA Hydro

Thomas TA Tractor

The Thomas TA was the second Thomas product. Fitted with four trailing-edge ailerons, and nacelle fuselage, early seaplane models had tubular wing floats.

At least two TA model were built, plus perhaps others built with varied motors of 65-90hp. The first was the 1910 model with exposed cockpit and interplane ailerons, which set an endurance record of four hours in 1912, piloted by Walter Johnson. One was tested as a single-float tractor version in 1912, but results were inconclusive.

The sole TA Tractor of 1912 had a partially-covered fuselage. It was probably a single-float conversion from a TA, but proved lacking in performance compared to the pusher.

The 1913 TA Hydro was the first all-metal hull in the USA.

Thomas Brothers B-3 / B-4

Thomas B-4

Built in 1912, the 2-3 seat B-3 and B-4 had a wooden hull covered with galvanized iron sheeting. A 1914 version incorporated streamlining, and 1915 model was a three place “luxury cruiser” with a mahogany hull.

In 1914, the Thomas Company advertised aviation for sport, war and business. Their earlier models, the B-4 and B-5 were used as trainers for civilian pilots seeking thrills, speed and fortune.

Three or four were built.
