ABSTRACT:
The convertible bar-puller provides a convertible tool for automatic lathes. This tool has two main parts; a housing head and a shank. The housing head is attached to the shank using an adjustable connection means allowing the housing head to be positioned vertically with respect to the shank. The shank includes flat sides and radius corners to be received in either an internal tool housing or an external tool housing on the turret of the lathe. Positioning of the head on the shank in a first position fixed with the shank even with the upper end of the housing head adapts the tool for an external tool housing while fixing the head in the middle of the shank adapts the tool for an internal tool housing. Jaws for engaging the object to be machined extend forwardly from the head and have an adjustable jaw opening. The jaws each comprise a finger portion and an end portion, the end portion received in a circular groove on a jaw setting screw internal to the head. Adjustment of the jaw setting screw engages the end portions of the jaws causing the jaw opening to be varied as the jaw setting screw is turned. Gripping caps may be added to the tips of the fingers on the jaws for protection of the fingers and by providing dissimilar length of the caps. Hexagon, octagon, or square material bars may be rotated to a position in which the flats may be engaged by the gripping caps. Knurling wheels may be added to each jaw to convert the bar puller into a knurling tool.
