Abstract: A pivoting means for pivoting back and forth a mechanical load (24) such as a print hammer about a given axis and within a low amplitude angle includes two elongated leaf springs (14, 16). The leaf springs are located in planes at a given angle with respect to each other but both planes being perpendicular to the plane of pivotation of the mechanical load. A frame (22) fixed relative to the pivotable mechanical load is used for attaching the extremities (21a, 21, 21c, 21d) of both elongated leaf springs. The mechanical load is attached to both leaf springs equidistant from their attached extremities. A power source (30) pivots the mechanical load from its rest position to its work or print position causing the two leaf springs to be flexed in torsion. The torsion flexing generates a return torque for self restoring the mechanical load back to its original position.

Abstract: A serial impact printer 11 includes a frame 15 mounted drive motor 47 coupled to a print wheel 31 to effect rotation thereof. The print wheel 31 is mounted on a movable print carrier 29 which serially moves from print position to print position along the print line. The motor 47 is coupled to the wheel pulley 51 of the print wheel 31 through a belt 49 which is wrapped about two idler pulleys 57 and 59 located on a sub-carrier 61. The sub-carrier 61 moves one half the distance of the print carrier 29 so that during escapement motion of the print carrier 29, the belt 49 imparts no rotary motion to the wheel pulley 51 and hence to the print wheel 31. The print carrier 29 may be clamped by clamp 77 to the belt 49 to effect the return motion thereof. The motor 47 is also coupled through a clutch 127 to the line feed apparatus of the platen 23.

Abstract: Two coaxially mounted spoked print wheels form a single printing element of a serial printer. Each wheel contains plural spokes having print characters thereon and a selected spoke is driven by a hammer to impact paper on a platen thereby effecting printing. Each wheel has a gap or window between two spokes of sufficient size to allow hammer or spoke entry. In operation, the window of one wheel and the selected spoke of the other wheel are rotated to the print position. The hammer is actuated to effect printing. The distance between the hammer and the selected spoke is maintained constant when shifting from wheel to wheel by shifting the wheel combination axially along its axis of rotation. The printing element is advanced relative to the platen and the platen is indexed to effect serial line printing. The two print wheels can readily be removed as a unit from the printer and replaced for type style interchangeability.

Abstract: The printwheel (20) includes a hub portion and a plurality of radially extending, deflectable petals (21) projecting therefrom. The petals include a pad or tip 24 thereon with print forming indicia (52) on one side (24a) thereof and a striking surface on the opposite side (24b) thereof adapted to be struck by a print hammer (30) to move the indicia (52) against a print receiving medium. The striking surface on side (24b) comprises first and second, oppositely inclined, radially spaced apart surfaces (25), (26), which are in superimposed overlapping relation in plan. Surfaces (25) and (26) are disposed to be engaged by complementary inclined surfaces (32), (33) on the print hammer (30) whereby angular misalignment between the hammer (30) and the petal (21) may be compensated for by lateral deflection of the petal (21) to effect a detenting between the complementary inclined surfaces (25), (26) of the petal (21) and the print hammer (30).
