Abstract
An exhaust distribution system for a building to automatically attach/detach to a vertical exhaust stack of a vehicle located within the building. The system includes an elongate track for guiding movement of a trolley therealong from a first position adjacent the entrance of the building to a second remote position at which the vehicle is to be parked. The trolley supports one end, e.g., a mouth, of a flexible hose and includes a guiding device to orient the hose's mouth with respect to the exhaust stack to receive the exhaust fumes therefrom. An assembly automatically biases the trolley to the first position on the track. The system also includes a blower, a pressure responsive sensor, and a solenoid controlled damper to automatically vent the exhaust fumes out of the building whenever the pressure in the hose exceeds a predetermined level, e.g., a pressure level which would exist if the vehicle's motor was running.
