Abstract

As shown in Fig. 1, a plurality of type bearing elements 10 are slidably positioned in openings 12 near the periphery of a multicam rotatable carrier plate or wheel 14. The type bearing elements 10 are disposed to be struck by a print hammer 16, shown in dotted outline, for impacting a ribbon and document, not shown, for printing thereon.

Type Wheel Assembly

As shown in Fig. 1, a plurality of type bearing elements 10 are slidably positioned in openings 12 near the periphery of a multicam rotatable carrier plate or wheel 14. The type bearing elements 10 are disposed to be struck by a print hammer 16, shown in dotted outline, for impacting a ribbon and document, not shown, for printing thereon.

A plurality of spring fingers 18 having enlarged head portions spanning two adjacent type bearing elements 10 as shown in Fig. 2, restore the elements after they have printed so that the shoulder 20 butts the multicam plate 14. The cam surface 22 locates the element 10 accurately in its rest position as shown in Fig. 3, and permits a slight peripheral motion of the type element in its forward position.

The disc 24 provides a forward stop for the element 10 and the back stop plate 26 provides a back stop. Spacer 28 serves to stiffen the spring action of fingers 18.
