12. Percussion drilling rig with locomobile (steam engine).

Percussion drilling rig with locomobile(steam engine).  In 1870 Albert Fauck, an engineer, introduced on the Bóbrka oilfield a new Pensylvanian method of drilling on cable. He used a locomobile to drive the rig. It was a drive system consisting of a steam boiler, steam engine and transmission system. The rotary movement of the machine,through a system of belts, cranks and pulling rods, was converted into reciprocating movement transmitted on a rocking beam, at the end of which a drilling set was suspended. The drilling rig cage had two drums with ropes wound on them to control the drilling set and remove the debris from the well by a bailer. The operations were carried out by a driller by means of levers. Such a device could drill boreholes to a depth of 500 m.
