mounted on legs or brackets 11 which raise the base from
table level. Referring to FIG. 1, an annular plate 12 is
mounted in ‘the lower left hand corner of the base 10
and a second annular plate 13 is mounted in the lower
right hand corner of the base 10, the plates 12 and 13
being adjacent each other. The plate 12 is bolted at 14
at a four to one ratio to the rotation of the large bevelled
gear 32. However, as can be seen in FIG. 3, one quarter
of the teeth of the bevelled gear 32 are removed at 36.
This reduces the ratio to a three to one ratio with a hesita
tion equivalent to one quarter of the rotation of the gear
32. During this hesitation the pick up of the stones takes
