The backchecking of dog clutches requires space and parts which may be in conflict with space limitations in typewriters. This clutching arrangement and cam/follower combination eliminates the need for complex backchecking assemblies. Dog clutches may be backchecked without the addition of a backcheck pawl and ratchet. When keylever 10 is depressed, latch 12 is rotated by means of link 14 which releases clutch ring 16 by a means that will be described below in more detail.
