Ordinarily, during the passageof the dial ing a synchronous vmovement with the' actuators, thus allo-wing lthe actuatorto :nove an extra carrying space. Serious difficulties are. always encountered ini devices for this purpose, for two reasons; First, during the rapid rotation of the dials, especially if there be Va'lslightest 'lost "motion, no matter meansmay be, the slightest 'over'rotation-M12o of 'said dials produces a blowupon the tripping mechanism, which is vsutiicientin rapid curaci Second: The second ditticulty is in "fthe" tact that it takes considerable power to trip the "partsjivhen in position shown in 'spring- 20, ivhatever the saine may begicaus- `,in gfc'onsiderable"friction between parts coi'- i'espoiiding to 27 and 12., and this requires :,111 iiiiieli'stroiiger spring tli'an-zwould be otherise, necessary.'
