Abstract
An improved type element mounting for a high speed type element positioning mechanism of the type which has a type head member having therein a plurality of type elements and a type head shaft on which the type head is mounted. The type head member has a spherical surface on which the type elements are mounted with the faces thereof on the sperical surface and movable in the type head member for being projected beyond the spherical surface. The type elements lie along latitudinal circles on the surface the centers of which lie on the axis of the type head shaft, and the type elements in adjacent latitudinal circles are substantially aligned along longitudinal circles extending from the point of intersection of the type head shaft axis and the spherical surface. The type head shaft is pivotally mounted for pivotal movement around a point corresponding to the center of the sphere of which the spherical surface forms a part. A type hammer is positioned adjacent the type head for striking a type element for projecting it beyond the spherical surface for carrying out a printing action. Each type element has a cylindrical shape with projection extending along the length thereof so as to …
