Model of a Jeer, Model of a mine consisting of four blocks. The blocks are strung together in pairs so that the discs per pair are perpendicular to each other and the outer and inner blocks of the line run parallel. Of the upper pair, the outer block has five discs, the inner three, of the lower pair the inner block three and the outer four. The hoist runs through the upper block to the inner block of the lower pair, from there and back between the two inner blocks, further to the lower block and finally back and forth between the two outer blocks., J.
