ABSTRACT:
A device for simple attachment to a water closet and tube extending to a location outside the building and room in which the closet is located. The device comprises a relatively small hollow housing having an opening for receiving gases when attached to the lid or seat of the closet, and an exit port and extension for connecting to the tube. The housing receives gases from the closet and directs the same from the housing to the tube and thus from the room and building. The gases are conveyed form the housing either by a motor driven fan or by normal convection currents.
