Abstract: A mobile liquid-dispensing apparatus usable for refueling airplanes and the like is provided which includes a reel-mounted, extensiblle and retractable, fluid delivery conduit connected to an adjacent liquid supply. Releasable one-way brake mechanism is also employed which allows extension of the conduit to a desired use position, but locks the conduit reel against spring-biased retractive rotation when the conduit has been extended. Selectively operable release structure associated with the brake allows spring-biased retraction of the conduit when the dispensing operation is completed. The conduit reel is preferably mounted for rotation about an upright axis and includes a guide for positive winding of the conduit in a helical manner about the reel during the retraction sequence.
