Abstract: A lockbox is disclosed, as for use in hotel closets, which includes an above-floor container fixed to define a space with a rectangular opening for closure by a locking cover. The cover incorporates a peripheral double ridge defining a peripheral channel to receive the upper edges of the container. Pairs of latching cam members are pivotally affixed at central, diametrically opposed locations in the cover, for actuation by a centrally located lock movement for engagement and disengagement with slots in the container. The movement is accomplished through a symmetrical linkage mechanism which simultaneously actuates each of the individual cam members and which incorporates a pair of parallel arms extending between pairs of the cam members and a pair of linking arms extending from the parallel arms to the lock movement. The pivotal support shafts for the cam members also serve as spacer mounts to support an internal cover for the locking mechanism.

Abstract: A system is disclosed for dispensing fuel, e.g. gasoline, from a reservoir tank into a consumption tank as in an automobile. The system incorporates two fluid flow channels, first a channel for liquid fuel and second a return line for fluid vapors. The channels include flexible hoses extending from a pump to a dispensing nozzle with rotatable or swiveled couplings. The couplings include two mating members affixed together to provide a fluid seal and relative rotation to accommodate swivel movement. One coupling member includes a fastening section which may be threaded to affix the coupling to a rigid structure, e.g. pump or nozzle. Also, the one member includes a somewhat cylindrical section defining an external, concentric groove for receiving a ring of nylon-like material. The cylindrical section of the one member is telescopically received within the other member which defines an internal groove for locking engagement with the nylon-like ring.
