Abstract

An adjustable needle-craft implement comprises an elongated graspable barrel having a longitudinally extending bore communicating between opposed ends of the barrel. The barrel includes a longitudinally extending plurality of mutually spaced apart transverse slots communicating with said bore's interior and form a barrel indexing rack. An elongated hollow cylinder supports a hollow tubular needle at one end thereof. The cylinder has a resiliently mounted cylinder indexing rack with transversely extending processes thereof that are adapted to be engagable in selective axial register with corresponding ones of the transverse slots in the barrel indexing rack. The cylinder is adapted to be received internally of the bore, in releasably lockable, longitudinally slidable relation therewith. The cylinder indexing rack is normally biased into releasable, selectively adjustable, mutually interfering axial register with an adjacently aligned portion of the barrel rack to thereby secure the cylinder and the barrel in mutually interlocked relation. The cylinder indexing rack is selectively operable against the bias, to disengage the interengaged cylinder and barrel racks to thereby enable selective longitudinal sliding adjustment of the mutually relative positioning of the cylinder and the barrel. In this way, the implement is adapted to adjustably position ones of selected portions of the needle's length beyond an adjacent end of the barrel, corresponding to selected ones of a predetermined plurality of relative positions of the barrel and the cylinder.
