Marcus, a motor carriage that was manufactured by Liechtenstein machine works in Adamov, Austria-Hungary in 1875-1888.
Siegfried Marcus was born in 1831 in Malchein in Mecklenburg. He worked as a mechanic at Siemens I Halske firm in Berlin. In 1852 he moved to Vienna, where he worked for some time at Vienna University. Since 1860 he got an opportunity to dedicate all his work to his primary interests – first of all electromechanics.
He solved many engineering problems and took out several patents. He got 38 patents in Austria-Hungary and even more in other countries. The magneto-electric ignition Marcus invented in 1864 won popularity and later on it was used for internal-combustion engines. Marcus carburetor patented in 1865 was first used for air-cooled engine produced by Langen I Wolf firm, later for the one he constructed.
At that time the air-cooled engines were considered obsolete, so Marcus took a great interest in the new invention of Nikolaus Otto. For designing an improved internal-combustion engine Marcus found a manufacturer in Vienna, a Polish aircraft designer plus an aviator, and a firm titled Marky, Bromovsky I Schulz in Prague.
Marcus adjusted the one-cylinder four-stroke engine for a motor carriage. This way one of the very first petrol automobiles appeared, capable of moving independently.
Its body was constructed of a wooden frame with two crossbeams. The front axle made of steel turned around the steering prop. Its cushioning was provided by two semi-elliptical springs. The rear axle was hard installed on two bearings, cushioned only by rubber silentblocks. The brake block worked against the steel bands of the rear wheels.
Its one-cylinder engine of 1570 cubic centimeters volume made up to 0.73 kW (1 horsepower) at 300 rpm. The revolutions were regulated with a valve. The cooling was provided by the natural circulation of water coming from a reservoir located under the back-seat.
In 1898 this self-propelled carriage was purchased by the Austrian club of motor-car enthusiasts. This vehicle is still in working order and is exhibited at the automobile museum of Vienna.
