Abstract: Disclosed is a gas cylinder ratchet driver tool that is specifically suited for opening and closing valve posts of gas cylinders. The tool comprises an outer handle body for one-handed use and an external ratchet switching actuator. Within the handle body is an internal housing that supports a rotatable socket therein. The socket comprises an elongated length with a lower working end adapted to engage a gas cylinder valve post and a ratchet gear upper end. A first and second wedge plate supported by the housing and acted upon by the actuator controls the ratchet direction by bearing against the ratchet gear, determining ratchet direction or ratchet lock. A flat spring beneath the actuator manipulates the wedge plates against the ratchet gear to control the ratchet direction. The socket working end comprises two flat portions to facilitate placement of the socket onto a gas cylinder valve post in emergency situations.
