Abstract
Abstract A linkage for supporting the hoses extending between a fixed portion of a machine and a shiftable carriage mounted on the fixed portion. A pair of links are pivotally interconnected with one of the links pivotally connected to the carriage and the other pivotally connected to the fixed portion. A clamp means is carried by the pivotal interconnection of the links and secures the hoses to the linkage to control the flexure thereof as the carriage is shifted.
