The apparatus is an automatic changeover system for a vehicle exhaust ventilating pipe. The exhaust pipe on a vehicle is fed into a valve which changes its output to either the conventional vehicle mounted exhaust outlet pipe or a bypass pipe low on the chassis to which a ventilating hose can easily be attached. The activating arm of an electrical switch is located at the end of the bypass pipe where it is held down by the ventilating hose when the hose is installed. Thus, when the vehicle is moved and the ventilating hose pulled off, the switch arm is released, and the switch activates a powered activator which moves the valve to close the bypass and open the output to the exhaust outlet pipe for normal operation.

[ What is claimed as new and for which Letters Patent of the United States are desired to be secured is:] [1.] A vehicle exhaust changeover apparatus to switch a vehicle exhaust from a normal exhaust outlet pipe to a bypass pipe to which is attached a ventilating hose, comprising:a junction between an exhaust inlet pipe, an exhaust outlet pipe, and a bypass pipe;valve means operating to direct gas from the exhaust inlet pipe into one of either the exhaust outlet pipe or the bypass pipe;a sensing means to determine when a ventilating hose is attached to the bypass pipe; andcontrol means interconnected with the sensing means and the valve means and controlling the valve means to direct gas from the exhaust inlet pipe into the bypass pipe when the ventilating hose is attached to the bypass pipe.
