  • Patent number: 3946964
    Abstract: An apparatus for rolling a collapsed hose into a roll which includes a frame having a pair of spaced-apart side rails and a crank for rolling the hose between the side rails. One side rail includes a keyed opening which receives the shaft of the crank and an axially extending spaced-apart pin on the shaft when the shaft is in a keyed orientation relative to the opening. The shaft of the crank is borne by both side rails and the axially extending pin cooperates with the shaft to engage a collapsed hose, which is wound about the shaft and pin by cranking a handle portion on the shaft outside the side rails. When the hose is rolled, the shaft and pin are brought into keyed alignment with the opening in one of the side walls and the crank is removed, permitting the rolled hose to be lifted from the frame.
