Belvallette Frères

They also invented several innovations that made the vehicles lighter and more practical, including a friction nail attached directly to the car body and a folding door handle.

[5] Other inventions belonged more to the category of curiosities, such as the Cynophore by Alfred Norbert Jacques Belvallette, a three-wheeled vehicle powered by dogs running inside the wheels.

A Break from around 1880 by Belvallette Frères is displayed in the Musée des Equipages in the Château de Vaux-le-Vicomte.

[7] They also built bodies for automobiles from a number of other brands, such as Charron, Delage, Delahaye, De Dion-Bouton, Gobron-Brillié, Hispano-Suiza, Hotchkiss, Lorraine-Dietrich, Minerva, Peugeot, Renault, Rolls-Royce, Voisin, and more.

[8] The Bibliothèque nationale de France has an album with 110 images of Belvallette Frères vehicles from the Georges Sirot collection, mostly albumen prints.
