Abstract
A manual crimping apparatus for attaching a ferrule to the end of a hose includes a pair of facing die carriers each having a pair of roller dies. The two die carriers may be moved toward and away from each other to establish the inter-die spacing between the die carriers in accordance with the outer diameter of the ferrule. Precise calibration of the inter-die spacing is provided by a plurality of selectively sized gauge blocks in one embodiment or the combination of a gauge stop pin and a plurality of apertures adapted to receive the pin which are spaced in accordance with a range of ferrule sizes. The four roller dies are free to rotate within their respective die carriers, with a first pair of die rollers having parallel axes of rotation and a second pair of die rollers also having parallel axes of rotation. The axes of rotation of the two pairs of roller dies are not aligned with the longitudinal axis of the ferrule such that when the crimping apparatus with its four roller dies tightly engaging the outer surface of the ferrule is rotationally displaced about the ferrule in a plane generally perpendicular to its longitudinal axis, the crimping apparatus moves along the length …
