Abstract: A cam and groove coupling joint has a male coupling having a substantially tubular body that includes a pair of grooves in the body and a female coupling having a substantially tubular body that includes two pairs of lugs on the body and further includes pins that are supported by each pair of lugs. A pair of cam arms are pivotally mounted to the pins between the lugs. The cam arms are movable between an open position in which the male coupling is free to move relative to the female coupling and a closed position in which a cam of each cam arm engages the groove to lock the male coupling inside the female coupling.

Abstract: A fuel can adapter is designed to be used with a fuel can having a neck that is internally and externally threaded. The fuel can adapter includes a plate having external threads for engaging internal threads of the neck, the plate including a hole. The adapter includes a sliding tube mounted to slide within the hole in the plate. The adapter includes an elbow mounted at an upper end of the tube, the elbow including an outlet. The adapter further includes a protrusion extending from the plate beside the hole. The elbow bears against the protrusion to exert a torque on the plate that threads or unthreads the plate from the neck of the fuel can.

A rotatable wire clip secures the cam arms in the closed position, the wire clip being rotatably connected to each lug between a secured position in which the wire clip secures the cam arm to prevent opening of the cam arm and an unsecured position in which the cam arm is free to be opened.
