Abstract
An imprinting wheel which comprises a plurality of annular disc members coaxial with a shaft and axially spaced therealong to define radially outwardly facing spaces therebetween and connected for rotation in unison. Printing type elements of rubber-like material have a printing portion terminating in a printing face and a base portion provided with an inner circumferential surface and joining ears which extend laterally of the printing portion. Adjacent pairs of disc members have first coaxially aligned annular shoulders forming first annular steps in the disc member which respectively engage the ears of a type element with the base portion extending across the space and the printing portion extending radially outwardly in the space and beyond the peripheral edges of the disc members, the first shoulders preventing radial outward movement of the type element. Annular resilient members have inner and outer circumferential surfaces. Each pair of adjacent disc members has second coaxially aligned annular shoulders thereon respectively forming second annular steps for engaging the opposite edges of the resilient member which has its outer surface engaging the inner surface of a type element. The unstressed outsidediameter of the resilient member is greater than the inside diameter of the second shoulders so that the resilient member is preloaded resiliently to resist radial inward movement of the type element.
