This is a vintage patent drawing from September 1, 1885, for a one-wheeled vehicle designed by J. O. Lose of Paterson, N.J. The drawing is sepia-toned and features a detailed illustration of the vehicle and a man operating it. The vehicle is circular, with a large wheel forming its base. A man is positioned within the wheel, appearing to be riding or controlling the device. He is wearing a hat, a vest, and trousers, and is holding an umbrella above his head. The mechanical components of the vehicle are intricately drawn, with various gears, levers, and supports visible. Labels with letters (A, B, C, etc.) are placed throughout the drawing, indicating different parts of the invention. The overall style of the drawing is typical of 19th-century patent illustrations, with precise lines and a focus on technical detail. The background is a pale yellow, and the text at the bottom provides information about the inventor, the patent number, and the date of the patent.
