Stone slab inverting mechanism - has stirrup with plates on spindle and worm drive shaft in arms gripping stone

摘要

The mechanism is particularly for inverting gravestones and other stone slabs, having stirrup with a lifting eye and a device gripping the stone. The stirrup is of rigid U-section, and a spindle (3) passes at right angles through one of its arms (1a), this spindle being equipped with a handwheel (3a) on the outside end. The shaft (6), coaxial to the spindle, of a worm drive (6a) on the outside, passes through the other arm (1b), and on the inside both shaft and spindle end in a plate (4, 4a), covered with discs (5, 5a) of elastic material and of dia. greater than that of the plates.
