TOILET BOWL VENTILATOR Filed March 2l, 1954 E j E nl: l IIIVEILUI Patented Dec. 3, 1935 UNITED STATES PATENT OFFICE Application March 21,
4 Claims.
My invention relates to improvements in toilet bowls and the object of my improvement is to provide a flue for conducting away the objectionable gases from a toilet bowl, and to provide a blower or suction unit for setting up a circulation in the ue. Among further objects is to provide means for making an electric circuit which shall automatically set the power unit in operation as soon as the toilet seat is occupied, and means for breaking the circuit when the seat is vacated.
In the drawing:
Figure I is a vertical section of the system,
Figure II is a sectional View showing the disengaged position of the rod which actuates the electric switch, and
Figure III is the same in a position of actuation.
The toilet is of the usual type, having a bowl I, an outlet conduit 2 leading through the oor 3, a pool of water A, and a ushing pipe 5. To these there is added ue 6 leading from the bowl I to the blower 'I, thence to vent 8 in the wall 9, floor 3, or ceiling.
The toilet seat II) is attached to the seat I by the hinge I 2 in the usual manner. An electric switch I3 located in the block II is actuated by the rod I4 situated in a chamber hollowed from the seat IIJ. A lever I5 with fulcrum I6 is joined to rod I4 through link II, and there is a coiled spring I8 encircling rod I4 and abutting at one end upon a pin I9 in the rod I4, and at the other upon the wall of the chamber in the seat III. The u'sual cover 20 is provided above the seat III.
The spring I8 normally expands longitudinally and forces the rod I4 forward. 'This disengages it from the electric button ZI of switch I3 and so breaks the circuit through wire 22 to the motor-blower l. The expansion of spring I8 also normally acts through rod I and link I'I to force the lever I5 into a vertical position so that the seat I is pried up somwhat from the rim of bowl I, as shown in Figure II.
The weight of an occupant upon seat I0 causes the lower end of the angular lever I to glide forword upon the rim of bowl I, and cause the upper end through link I'I to force back the rod I4, compressing spring I8, and causing rod I4 to impinge upon button 2| of switch I3.
1934, Serial No. 716,640
AAs long as the seat I0 is occupied, the electric Contact is maintained and the blower 1 produces a current of air from bowl I through the flue 6 and out through vent 8, thus preventing any befouling of air within the building, 5
I claim:
l. A toilet bowl having in combination a conduit leading from the bottom of said bowl, a pool of liquid in the bottom of said bowl, a flushing pipe entering near the tcp of. said bowl, a ue leading 10 from the top of said bowl, motor means for producing a draft in said ilue, a block above said bowl, a seat also above said bowl, a hinge joining said block and said seat, an electric switch in said block, a rod in a chamber of said seat, a spring encircling said rod and tending to separate said rod and said switch, a link attached to the end of said rod, a lever attached to the end of said link, and an electric connection between said switch and said motor means.
2. Electric operating means for a toilet comprising a block attached to the top of a toilet bowl, a seat hinged to said bowl, an electric switch in said block, a rod in a chamber of said seat, a spring encircling said rod and tending to separate said rod and said switch, a link attached to the end of said rod, a lever attached to the end of said link, and a flattened portion upon the rim of the toilet bowl for making contact with said lever.
3. A toilet having a bowl, a block attached to the rim of said bowl, a seat hinged tosaid block, an electric switch in said block, a rod in said seat for operating said switch, a spring encircling said rod, and lever means for converting the downward movement of said seat into the longitudinal movement of said rod.
4. A toilet bowl having in combination, an inlet for ilushing liquid; an outlet tor gases, said outlet consisting of a tube rising vertically from the bowl, thence passing horizontally over the mouth of said inlet and over the rim of the bowl, thence downwardly, and finally horizontally to a vent; and an electric fan within said outlet tube near the vent.
