Abstract: A portable lubricating apparatus is illustrated which utilizes an upright removable and replaceable container of grease for delivery through a hose and nozzle carried on a wheeled chassis wherein a frame is carried adjacent one end of the wheeled chassis receiving the container of grease in such a way that a connection with the dispensing mechanism is effected by the act of replacing and installing a new container of grease.

Abstract: A portable self-contained lubricating apparatus having a closed filling and dispensing system includes a wheeled frame member, a vertical lubricant container having an inlet and a bottom discharge outlet, and a flexible bladder carried within the container for pressurizing the lubricant with compressed air. A gear pump dispenses the lubricant from the container through a dispensing outlet at an elevated pressure. A rechargeable power source and a power drive is carried on the frame member for energizing and de-energizing the pump in response to respective low and high pressures at the dispensing outlet. A valve coupling member is connected to the container inlet having a pressure coupling for receiving a tubular connector to connect the container to a closed source of lubricant and a valve member for opening and closing a passageway between the inlet and pressure coupling providing a closed automatic filling system avoiding contact with outside contaminants and minimizing any exterior residue of lubricant.
