Daimler patent: engine with vertical cylinder

Gottlieb Daimler submits a patent application for an engine with vertical cylinder. Daimler developed the unit jointly with Wilhelm Maybach on the basis of his 1883 horizontal test engine. The single-cylinder engine, registered as patent no. DRP 34 926 on 1 April 1886, is no longer powered by gas but petrol. This first high-speed petrol engine is dubbed the "grandfather clock" on account of its shape.
