DEFINITION

Classification: 400/372

And rotatable cam (e.g., single-lobe cam):

(under subclass 370) Subject matter wherein said continuously rotated cylindrical member intermittently drives a component, which component has a cam surface and turns around an axis to move a lever on which the component is mounted.

(1) Note. A "cam surface" is defined as the edge periphery of a disc that oscillates or rotates about an axis, the radial distance from the axis to the periphery varying around the periphery. The cam is mounted on a lever that is pivotally mounted and is connected to the type-bar* action linkage. When the cam is temporarily connected to the cylindrical member, the cam rotates about its axis, thereby pushing the lever through the pivot axis of the cam. The resulting oscillation of the lever actuates the type-bar linkage.
