April 3, 1885 – Grandfather clock engine is patented

Gottlieb Daimler and Wilhelm Maybach started developing what would become known as the Grandfather clock engine in the early 1880s in a garden shed behind Daimler’s home in Cannstatt, Germany. The upright 0.5 hp engine, which featured a single horizontal cylinder, air cooling, hot tube ignition and cam operated exhaust valves, weighed in at approximately 50 kg (110 lb) and had a height of 76 cm (30 in). The engine, patented on this day in 1885, was fitted to the Reitwagen the following November, thus becoming the first vehicle powered by an internal combustion engine, and the first modern motorcycle, although it had stabilizers similar to a child’s bike with training wheels. Maybach rode the vehicle for three kilometers (two miles) alongside the river Neckar, from Cannstatt to Untertürkheim, hitting a top speed of 12 kilometers per hour (7 mph). The 1885 Grandfather clock engine.
