Laminated sieve with crank mechanism - has bell-crank lever and adjusting rod attached to operating rod parts

摘要

The laminated sieve comprises two sets of laminations mounted parallel to each other in a frame and on a crank wire with crankpin. A two-part actuating rod fits round the crankpins and slides in the lengthwise direction, there being adjusting mechanisms between it and two setting levers. On one part of the rod is a bell-crank lever, attached eccentrically to the first setting lever. To the other part is attached an adjusting rod, eccentrically attached to the second setting lever, which pivots on the bell-crank lever.PS.
