Abstract

The engagement of the pawl is determined by a pin 61, the position of which is controlled by projections 57, 58 on intergeared pinions 59, 60. The projections 57, 58 are in different planes and are engaged alternately by abutments on a U-shaped member 67 on a control spindle 68. Specifications 374,908, 407,952, and 419,205, [all in Group XXXVIII], are referred to.
