Abstract: An automated cylinder connector is disclosed, which substantially reduces the time required to connect and disconnect a gas line from a gas cylinder. In one embodiment, a threaded connector, defining a conduit for gas flow, is designed to be attached to the valve outlet of a gas cylinder. The connector includes a threaded collar having a bevel gear which engages a similarly shaped bevel gear on an independent, motorized drive member. When the drive member is held against the threaded connector, so that the bevel gears are engaged, and when power is applied to the drive member, the collar on the connector rotates, and is threadedly engaged with the gas cylinder. In another embodiment, the threaded connector takes the form of a turbine which is rotated by a stream of compressed air. Rotation of the turbine screws the connector into the gas cylinder. In both embodiments, a plurality of threaded connectors can be grouped together, and suspended above a plurality of cylinders, by a set of springs.

Abstract: A palletized cylinder distribution system facilitates the transportation and distribution of gas cylinders. The system includes a network of members and cross members, this network being mounted on the rear of a truck. A walkway is disposed on the network, the walkway dividing the network into at least two regions. The surface of the walkway is raised from the level of the network. Pallets of gas cylinders are placed on the network, forming rows on either side of the walkway. The pallets have base portions which include laterally extending tabs. The tabs hold the pallets in place by engagement with a flange defined by the walkway, and with another flange disposed on side rails attached to the network, on the other side of the pallet. The truck has no flatbed of its own; the bases of the pallets, together with the surface of the walkway, define the bed of the truck. Access to the cylinders is obtained through the walkway.
