Water is caused to enter the said bowl by means of a hollow fixed stopper which is provided with an air tight valve. AA lien the said valve is closed the water remains in the tank, and when the valve is opened the water flows into the bowl through openings in the lower part of the reservoir or tank. The said reservoir 10 must also be provided with an ordinary or pneumatic tap which is used when water is required for washing purposes, that is to say when the outlet at the bottom of the bowl lias been closed and the latter is to be used as a wash bowl or the like. This construction has the special advantage as compared with ordinary spitoons 15 more particularly for dental purposes, that the necessity of providing a separate wash-bowl is obviated. Further by closing the outlet opening of the bowl and opening the valve stopper the cleansing of the bowl is facilitated. To the tap a cup may be attached so that a separate support for the latter is rendered unnecessary. To facilitate the emptying of the waste receiver the latter is 20 supported by a plate resting upon rollers, the said plate being connected with the door of the pedestal in such a manner that when the said door is opened the said receiver is moved forward. The bowl or spitoon is supported at the upper part of the pedestal and the upper walls of said bowl are formed by a tank or reservoir which may be made 2h in one piece with the bowl or may be removable. The said reservoir is provided with one or more small openings through which water introduced into the reservoir through a suitable opening can pass into the bowl or spitoon when the hollow air-tight valve stopper of the said opening is open. A short india- rubber tube preferably leads downwards from the outlet opening at the bottom 30 of the bowl. Inside the pedestal a waste receiving vessel stands upon a plate which is connected with the door of the pedestal and provided with a roller or rollers or the like so that on opening the said door the vessel is moved out of the pedestal and vice versa. In details the construction of the spitoon may vary, the whole of the lower 35 part of the bowl may form the waste receiver and be provided with a tap. To the inner side of the door of the pedestal a towel rail or the like may be fastened and the pedestal may be provided with drawers or other convenient devices.
