This is a vintage patent drawing of a velocipede, an early type of bicycle. The drawing is done in a detailed, technical style with fine lines. The velocipede has two large wheels (B) with numerous spokes. A smaller wheel (A) is positioned at the rear. The frame is constructed of metal bars and supports a seat for the rider. A complex gear and chain system (e, f, g) connects the pedals to the rear wheel, providing propulsion. Two men are depicted operating the vehicle. The front rider wears a hat and is positioned to pedal the machine. The rear rider is standing and appears to be steering or providing balance. Both men are dressed in period clothing, including hats and suits. Labels (A, B, C, D, E, F, G, H, I, J, K) are used to identify various parts of the velocipede. The drawing is accompanied by text indicating the inventor (S. Wortmann of New York), the patent number (No. 93,030), and the date of the patent (July 27, 1869).
