to the rear is a lever 3d with a right angle ex' tension 35 which is positioned to swing into engagement with switch trip-arm 43a when weight is applied to the seat 2, the front end of which rests on buffers 33 while the rear is normally held up a predetermined distance as controlled by the mating stop offsets or lugs 31, 4i, projecting on the opposed surfaces of the arms and plates and by springs 39, the latter yielding under weight until the bui-Ier d!! contacts the rim of the bowl. In such movement, the trip-lever 34 operates the switch arm l8a and starts the motor. When the weight pressure is released from the seat, the spring 39 raises the rear thereof and the lever 34 comes to position to release the switch arm ld and the switch stops the motor. Preferably a time-delay type of switch is employed, in order to insure removal of all waste air before the fan stops. Over the seat is a lid 42 which has attached to its rear an arm 43 hinged to shaft 3|. As the lid buffers 45 are aligned over the seat buffers 36, and not to the rear thereof, it is seen that weight pressure applied to the lid is prevented from causing operation of the switchcontrol lever 34 4such as to start the motor.
Where the flushing water is supplied directly by an appropriate supply valve instead of from a flush tank, the operation of the present construction is of course the same.
In the form of the fan valve shown in Fig. 4, the fan Y[2a is generally of cylindrical cupped form closed below and having radial blades |3a. The Xed sealing'tube |5a again extends as a passage-way connecting from duct l0, and is slightly spaced up from the depressed bottom of the cupped fan body, whereby water therein may seal the lower end of the tube 15a. The fan body is provided with small openings s which coincide with openings in the fan blades and allow passage of water, the openings being so designed as to open away from the direction of the fan rotation. When the motor I1 is energized, the centrifugal action in the fan throws the liquid out through the openings s and also especially through the open top of the cupped fan into the space or reservoir surrounding the fan, and the lower end of the tube la being freely exposed allows passage of air from the duct l0 through the fan to the discharge duct 2i. As the fan is stopped water will begin to flow back through openings s into the fan cup, and its depression below the tube i511 is filled and re-seals the lower end of the tube l5a to prevent upward passage of air. Due to the circular shape of the fan body without externally projecting blades, it turns with very small resistance in the liquid.
In the modification shown in Fig. 5 the construction again includes the motor l'l and the fan with blades I3b, and the i-lXed central tube lh therewithin to seal by its lower end in water. The centrifugal force of the fan in rotation causes the liquid in the chamber 50 to swirl outwardly thereby exposing the lower end of the tube E51) and allowing free passage of air as drawn by the fan down through the tube and into the vent duct 2|. Upon the stopping of the fan, the water ows back to the center and re-seals the 4 lower end of the tube, and passage of air is prs vented.
Instead of using water as the sealing liquid, other liquids of non-evaporating character can be used, as for example mercury, and since there is normally no occasion for loss of liquid in its series of movements to the periphery and back, a charge of liquid can last indenitely, and such a valve is of especially Wide usefulness.
In the form shown in Fig. 6, the motor l1 is again arranged to drive the fan having the fan blades |30. The fixed sealing tube l5c is positioned such that its lower end dips into the depression or well Mc for but a slight distance, and the water in the reservoir adjacent thereto eX- tends but slightly above well ldc; consequently only a slight pressure is required to force air down through said tube by the fan; however, considerable pressure is required to force air up through said tube as the entire amount of liquid in the reservoir above the lower end of the tube must be forced up through the tube before any air can pass through. This differential of pressure required is thus of particular advantage.
In all forms of the invention, as seen, vwhen weight is applied to the lid 42 the fan is prevented from operating, but when weight is applied to the seat 21 the fan is operated and its water seal is simultaneously opened for free draw-off of air from the bowl to the vent pipe. But when the fan stops after removal of weight from theseat, the water again flows back center-wise and closes the fan seal as a valve, and passage of air back from the sewer side is prevented.
By the provision of a supply opening and closure plug 53 over the opening 23 (see Fig. 1) antifreeze material may be supplied through the opening 23 and duct l0 to the fan valve compartment for protection thereof in the event of any occasion requiring such.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims or the equivalent of such be employed.
