The structure is such that, upon thevtnrn-V@ ing of the disc 15, in the direction indicated by the arrows in Fig. Land in Fig. 1, the p a te 9 will be shifted longitudinally in the direction indicated by the arrow'vl9, so as to be moved directly rearwardly ofthe plate 8 andthe plate f8 buckligsuiciently topermit-its movement.
