Description

Patented June 13, 1944 VENTILATED CLOSET BOWL Alfred W. Thompson and James B. Armstrong,
' Ekalaka, Mont.
Application August 5, 1943, Serial No. 497,492
3 Claims.
Our invention relates to closet bowls, and has among its objects and advantages the provision of an improved ventilated bowl.
In the accompanying drawings:
Figure 1 is a side elevational view of a bowl illustrating ourv invention applied thereto;
Figure 2 is a detail View of a cover-actuated switch structure;
Figure 3 is a sectional view along the line 3--3 of Figure l;
Figure 4 is a detail view of a. trip; and
Figure 5 is a perspective view of a bolt.
In the embodiment selected for illustration, the bowl I0 is provided with a seat I2 having a seal I4 attached thereto for engagement with the bowl in the closed position of the seat. A cover I6 normally overlies the seat I2, this cover being xedly secured to a shaft |'8 rotatably jcurnaled in supports anchored to the bowl structure l0 in the usual manner. Seat I2 is pivotally connected with the shaft |8.
A Water inlet pipe 22 places the bowl I0 in communication with the Water tank 24, communication being controlled by the usual valve 26 having seating engagement at 28 with the upper end of the pipe 22. To the pipe 22 is connected an air exhausting pipe 30 leading to a fan housing 32 having an exhausting conduit 34 leading to the atmosphere.
In Figure 3, a fan 36 is located inside the fan housing 32, and this fan is connected with the shaft 38 of a motor 40 mounted inside a chamber 42 inside the Water tank 24, the chamber being watertight with respect to the tank. Bolts 44 secure the fan housing 32 and the motor to the wall 46 of the tank 24, the motor being clamped across rubber cushions 48 engaging the wall 46. Rubber sleeves 50 are provided for the portions of the bolts 44 extending through the Wall 46 to dampen vibration.
The bottom of the water tank 24 is formed with a chamber 52 Within which is mounted a housing 54 having a flange 56 bolted at 58 to the tank wall 60. The housing 54 is also bolted at 62 to the tank Wall 64. A crank arm 66 has one end secured to the shaft I8 and its other end pivotally connected at 68 with one end of a link 'I0 having its opposite end pivotally connected at 12 with a trip and switch slide I4.
Upon the wall 16 of the housing 54 are mount- To the slide 14 is xed a post 84 provided with a bridge element 86 arranged to have engagement with the contacts 'I8 to close the circuit through the motor. The crank 66 exerts a pull on the link 10 when the cover I6 is moved to an open position for bringing the bridge element 86 into bridging engagement with the contacts 'I8. When the cover I6 is moved to the closed position of Figure l, the slide I4 is advanced to the dotted line position of Figure 2, at which time the bridge element 86 is positioned clearof the two contacts 18 for breaking the circuit through the motor.
A bell crank 88 is pivotally mounted on a bolt 90 secured to the side walls 82 of the housing 54, the arm 94 of the bell crank being pivotally connected at 86 with the lower end of a link 98 having its upper end pivotally connected at |00 with a crank arm |02 at one end of a shaft |04 rotatably journaled in the side walls |06 of the tank 24. An arm |'08 is fixedly connected at one end with the shaft |04 and is provided With the usual link connection I I0 for actuating the valve 26.
The arm ||2 of the bell crank 88 is arranged in the path of a trip ||4 pivotally connected at ||6 to one end of the slide '|4, see Figures 2 and 4. In Figure 4 a spring ||8 is bolted at |20 to the slide 'I4 and engages the trip I |4 to yieldingly hold the trip in the positions of Figures 2 and 4. With the cover I6 in its open position, the trip ||4 lies close to the arm ||2 to engage the arm when the cover I6 is lowered for pivoting the bell crank 88 to its dotted line position of Figure 2. Such movement of the bell crank lifts the valve 26 off its seat 28.
'I'he bolt 90 is provided with a square end |22 fitting a similarly shaped opening in one of the side walls 92 so as to be restrained from rotation. A slot |24 is provided in the bolt 90 within which is secured one end of a spring |26, the other end of the spring engaging a lug |28 on the arm 94 to urge the bell crank to the full line position of Figure 2.
A rubber bumper |30 is mounted on a flange |32 on the end wall |34 of the housing 54, this wall and the wall 64 being provided with a common opening |36 to accommodate pivotal movement of the arm 94. The bumper |30 is arranged in the path of the arm 94 so as to strike thereagainst when returning to its full line position of Figure 2.
As the bell crank 88 is pivoted to its dotted line position of Figure 2 the trip I|4 slips underneath the bell crank to permit the spring |26 to return thebell crank to its full line position.
It will thus be seen that we have provided a Ventilating system wherein the circuit'of the motor is closed when the cover I6 is raised to an open position and in which manner closing of the cover breaks the circuit through the motor. Thecoyer I6 is maintained in slightly spaced relationship with the seat I2 by the usual pads |38.
The tank 24 is provided with the usual water inlet pipe |40.
Without further elaboration, the foregoing will so fully illustrate our invention, that others may,
by applying current knowledge, readily'adaptthe same for use under various conditions of service.
We claim: 1. In a closet bowl having a cover and a water tank and a valve vfor placing the Water tank in communication with the bowl, a motor driven fan, an air inlet communicating with the bowl" and the fan, an air exhaust conduit communicating with said fan, a switch'for opening and closing the circuit of the motor, a slide member operatively connected with said cover to close said switch when said cover is moved to an open position and to open the switch when the cover is .for movement to its closed position.
moved to a closed position, and a valve actuating means operatively connected with said slide member :for opening the valve when said cover is moved to a closed position.
l2. The invention described in claim 1 wherein said valve actuating means comprises a pivotally mounted bell crank having one-arm thereof arranged in the path of said slide member and its other end operatively connected with the valve, and a Spring means for returning the bell crank to its normal position to release said valve 3. The invention described in claim 1 wherein said slide member is provided with a trip and in which said valve actuating means comprises a pivoted bell crank' having one arm thereof arranged in the path of said trip and its other arm operatively connected with said valve, said trip engaging said first arm of the bell crank for pivoting the latter to a valve opening position when said cover is moved. to a closed position, and a spring means acting on said bell crank to return the latter to a normal position for releasing the valve.
