Abstract: HAMMER ASSEMBLY A hammer assembly comprising a housing having opposing open ends and an internal passage extending between the open ends. A hammer element is positioned in the housing for reciprocal movement in the passage between first and second positions. The hammer element has an opening formed therein in which a biasing member is positioned. When enabled, the biasing member is capable of biasing the hammer element in a desired direction relative to the first and second positions. The housing is desirably fabricated of a self-lubricating material with the area of the opening at one of its ends being substantially larger than the cross-sectional area of the hammer element taken along a plane perpendicular to the axis of motion of the hammer element at such one end in order for air to be freely vented from the passage during reciprocal movement of the hammer assembly.

Abstract: EASY-LOAD RECORD MATERIAL FEED APPARATUS Apparatus for feeding marginally punched record material comprises a main support member, and a plurality of drive pins mounted to the main support member for movement along a predefined path past a first location at which record material is inserted into the apparatus. Means included on the main support member adjacent the first location facilitates the buckling of record material inserted into the apparatus in a direction away from the pins during movement of the pins along the predefined path when there is no initial engagement of a pin with a marginal opening of the record material. When a pin thereafter moves into substantial registration with a marginal opening of the record material, the natural bias of the buckled portion of the record material in the direction of the pins will return it to a substantially unbuckled state to thereby engage the pin with the opening.

Abstract: PRINT MEMBER CARRIAGE ASSEMBLY A carriage assembly for transporting a print member along a predetermined path adjacent a support member comprises a first carriage section adapted to be mounted adjacent the support member for movement along the predetermined path, apparatus for mounting a print member to the first carriage section for movement between first and second positions relative to the support member, and apparatus coupled to the mounting apparatus for retaining a print member mounted to the frame in each of its first and second positions. The retaining apparatus includes a biasing member for biasing the print member in a direction opposite its second position when at its first position and in a direction opposite its first position when at its second position. The biasing member preferably includes an over-center tensioned spring coupled between the first carriage section and the mounting apparatus.
