Abstract
A normally engaged toothed cone clutch mechanism to allow disengagement of the platen of a typwriter from a line indexing ratchet wheel to enable rotation of the platen independently of the ratchet wheel includes a clutch member and a connection between the clutch member and the ratchet wheel. The connection takes the form of a spring washer secured to the clutch member and pins extending axially from the ratchet wheel toward the clutch member. The spring washer is formed to embrace and grip the pins to transmit rotary motion of the ratchet wheel to the clutch member without play yet allow axial sliding movement of the clutch member to disengaged position while maintaining its connection to the ratchet wheel.
