Abstract:
A linkage attachment device is used in cold weather in combination with f and water dispensing nozzles having triggers for opening and closing valves for dispensing liquids and for stopping the flow of liquid, without manual contact by the user with such nozzles. Means are provided for preventing the unintended opening of the valves and for limiting the degree to which the valves can be opened by actuating the linkage attachment device.
