Someone came around and finally the mistery is solved.
Let me try and explain ...
Imagine a sort of chain, praying rosary style, with its beads. Then consider breaking the rosary, introducing it in a tube, where the beads fit precisely its interior diameter. After that, you introduce the tube in a water container and start rotating the rosary in the sense that the beads go up the tube. The result will be that the water is transported to the top, in quantities retained inside the beads interval.
That is the principle of water pumping in which this auger is used; for drilling a hole through a pine trunk where the beads (cork plugs) elevate the water, tractioned by some crank & handle resource.
No wonder this pumping system is called rosario (rosary) or de contas (beads).
