Abstract

Disclosed is a drive magnet armature assembly. This device is mounted near a spring clutch such that the shoe 10 may engage the spring of the spring clutch. Drive magnet 12, when energized, will attract armature 14. As armature 14 is attracted about pivot point 16 extending spring 18, the shoe is moved downward into engagement with clutch spring 20 wrapped around shaft 22. This radial engagement by shoe 10 toward shaft 22 will cause the clutch to wrap onto shaft 22, thus activating the clutch. Prior drive magnet armatures provided either cumbersome or only very coarse adjustment of the position of shoe 10 with respect to the clutch spring 20.
