The ancient mechanisms that were used several centuries ago are of great interest to us, especially if they are preserved in the working form. We will get acquainted with one of these mechanisms further.
In front of you is an industrial museum in Bad Közen, Germany. The museum is a small factory of the XVIII century, engaged in the extraction of mineralized water from wells for the subsequent production of salt from it. The water was pumped out with pumps, the energy for the work of which was produced by a water wheel. The device operates to this day, transferring mechanical energy from the wheel to the pumps by 175 meters. And this energy is transmitted through the reciprocating movements of wooden bars on the swinging supports.
In the background there is a cooling tower, on the front – rocking supports of a wooden power transmission line.
In the video, the pedestals swing from 1:10. The transmission lines of mechanical energy have their history since the 16th century. They were used for pumping water from mines, as well as for lifting and grinding ore, lifting-descending people, ventilation. They could change direction (to go around the obstacle or go first up the hill, and then down), and in extremely extreme cases reached 4 kilometers. Germany, 1765:
Part of a system of 140 dams, 600 kilometers of canals and 200 water wheels to service mines in the Harz Mountains, Germany:
An advanced mechanism of the XIX century one of the largest water wheels on the British Isle of Man:
Here, the bars are fixed on rollers that roll on rails and transmit power of about 150 horsepower for a distance of 200 meters
Special devices allowed to distribute the work of one engine to several pumps.
This is in Canada (apparently, the system is working and used for its intended purpose):
American system Jerker line, widely used in the oil industry. Here everything is on ropes:
In action it looks like this: In the second half of the 20th century, the described mechanisms almost disappeared from widespread use, but in places they were preserved in the museum and even in practical applications.
