A base-lock type font holder for imprinting apparatus of the impacting type, the holder comprising selectively spreadable aligned parallel rows of base lock segments which are clamped together within the outwardly opening cavity of a carrier body with the type font seated therein. An internally spring biased ratchet like arrangement facilitates both clamping and retention of the type font therein immovably during as many as several million impacts effected by the imprinting apparatus. The ratchet-like arrangement includes a pair of free-mounted miniature puck members seated at opposite ends of a coil spring, together seated in bearing relation to clamping screws employed to secure the segments within the cavity, and said screws being capable of manual manipulation against the spring bias selectively to spread or clamp said segments.
A base-lock type-font holder for use with an imprinting device comprising a body having an outwardly opening cavity of generally rectangular configuration and a peripheral rim surrounding said cavity, a plurality of base-lock segments each having at least a pair of transverse passages and arranged in parallel rows within said cavity with said passages thereof aligned coaxially, said rows of segments defining parallel type-font holding grooves, a pair of spaced passageways formed in each of a pair of opposite portions of said peripheral rim, screw means engaged through said passageways and passages of said segments, said screw means having a head portion at one end, said head portion being of a configuration defining opposite side surfaces, means carried by said screw means for clamping said segments tightly upon rotation of said screw means in one direction for securing the type-font within said holding grooves and in the opposite direction for releasing same, a connecting bore formed in one of said rim portions communicating between said adjacent passageways and resilient means within said connecting bore in bearing relationship with a facing side surface of said head portion of said screw means with force sufficient to bias said screw means against non-manipulated rotation particularly in said opposite direction.
A printing type carrier for imprinting devices formed as a body of generally rectangular configuration having an outwardly opening cavity of generally rectangular configuration and an upstanding rim adjacent said cavity, base-lock segments arranged parallel in adjacent rows within the cavity, each of said segments having passages formed therein for axial alignment when installed within said cavity, two pair of aligned passageways in the body opening to the interior of the outwardly opening cavity and positioned for alignment with the aligned passages of said segments when same are installed, at least one internal connecting bore formed in said body communicating between the adjacent passageways on one side of the body, a coil spring disposed within said connecting bore and puck members disposed at each end of said coil spring, a pair of elongate screws, each having an enlarged head and a threaded leading end, said screw adapted to be passed through said passageway and the aligned passages of the segments and threadably engaged within the opposite passageway, each head of said screw having a generally polygonal cross-section and each screw carrying a circumferential groove proximate the head and a retaining ring is seated within said groove, rotation of said screws causing said segments to be forced together in clamping relationship with type font seated therebetween.
A base-lock type-font holder for use with an imprinting device comprising a body having an outwardly opening cavity of generally rectangular configuration and a peripheral rim surrounding said cavity, a plurality of base-lock segments, in parallel rows within said cavity to define parallel type-font holding grooves, a pair of spaced passageways formed in each of a pair of opposite portions of said peripheral rim, screw means engaged through said passageways and segments, means carried by said screw means for clamping said segments tightly upon rotation of said screw means in one direction for securing the type-font within said holding grooves and in the opposite direction for releasing same, a connecting bore formed in one of said rim portions communicating between said adjacent passageways, resilient means within said connecting bore in bearing relationship with said screw means whereby to bias said screw means against non-manipulated rotation, and a communicating bore formed in said body communicating with said connecting bore, the axis thereof being normal to the axis of the connecting bore, said communicating bore adapted to receive a tool therein for urging said resilient means out of intersecting relationship with one of said passageways to enable said screw means to be introduced therein.
