DEFINITION

Classification: 400/161.5

Via multiple cam surfaces:

(under subclass 161.1) Subject matter wherein said mechanism for selecting or choosing the particular type-face* is driven by a plurality of cam surfaces that are connected by way of cam surface followers to the type-head* that supports type-face elements, one of which elements is to be selected or chosen for impression.

(1) Note. A "cam surface" is defined as the edge periphery of a disc that rotates about an axis, the radial distance from the axis to the periphery varying around the periphery. As the disc rotates, the distance of a follower that is in contact with the periphery will increase and decrease relative to the axis of the disc, thus the rotation of the disc will effect substantially radial movement of the follower. The cam surfaces may be on separate disc elements or may be on a single member having separate cam surfaces.
