Abstract

In single element typewriters where increased numbers of alphanumeric symbols are placed on the typing ball, it is mandatory that the clearance between the removable type ball and the lug upon which it is inserted on the carrier of the machine be reduced to a minimum to insure proper impact of the ball symbol at its desired place on the paper carried by the platen.

Type Element Mounting Configuration

In single element typewriters where increased numbers of alphanumeric symbols are placed on the typing ball, it is mandatory that the clearance between the removable type ball and the lug upon which it is inserted on the carrier of the machine be reduced to a minimum to insure proper impact of the ball symbol at its desired place on the paper carried by the platen.

To this end, the carrier may be provided with an insert for male member 10 having dissimilar projections, for example, in width or length, such as the projections 11 and 12 which are diametrically opposed, or of a different width or length from each other as well as different from the lugs 13 and 14 which are 90 Degrees displaced from the lugs 11 and 12. In a like manner, the element 15 may contain like notched or recessed portions 11A-14A which are sized for mating engagement with the lugs 11-14, respectively, to thereby inhibit free play or "slop" in the system. Additionally, the differential in sizes of the lugs, at least two, as well as the recesses in the typing element 15 aid in proper orientation of the element when it is being inserted in a machine.
