ABSTRACT:
A pneumatic liquid injector de-icing system designed for use on air brake lines of a train includes an alcohol storage tank provided with fittings for engagement between the train air supply lines and the train brake lines. The storage tank may be provided with a pressure gauge for monitoring pressure in the system. In use, when operating in cold conditions where brake line freezing is encountered, alcohol is introduced into the brake lines. The alcohol absorbs moisture and thaws ice in the brake lines so as to prevent ice-up. In an alternative embodiment, one line of the storage tank is terminated by a plunger so it may be used to unclog toilets. In yet another alternative embodiment, one line of the storage tank is adapted to be connected to an RV so the latter may be winterized.
