A. RoNNlNG VENTILATOR Oct. 18, 1932.

Filed March 50, 1929 INVENTR (Acglph (Rormgg ATTRN gli@ y Patented 18, 1932 UNITED STATES PATENT oFFlcE ADLPH RONNING, F HINNYOIS, IINNESOTA van'rm'ron 7 appuauon mannen so, 192s. smal No. 351.2214. y

This i invention relates to Ventilating devices for closet bowls and the primary object is to provide a simple, efficient, and practical mechanism for carrying ofi' offensive odors before they are permitted to escape into the ing and Ventilating, and thus render it un-.

necessary to provide`the bowl proper with other or additional equipment for connecting the Ventilating equipment. A further ob'ect is to rovide a ventilator tube with an e ectrical y operated fan or blower for creating the necessary Ventilating current therethrough, and to insulate the tube or flue from vibrations of the fan motor so as to eiectva 2o quiet operation thereof. A further object is to provide a circuit connection for the fan motor including a switch that is automatically o ened and closed by pressure on and oli ofv t e bowl seat whereby the fan will be operative to eiect a forced ventilation only when the cover is opened and the seat is in use, but which will be inoperative when the cover is down as when the bowl is not in use. A further obJe'ct is to provide an improved 3o and simple design of construction for the motor, fan, and fan housing, whereby the motor and fan may be readily removed for cleanin oiling, or repair purposes. These and stil other objects will be disclosed in the course of the following spx'aciiication,y ref- `erenee being had to the accompanying drawinz'm which s Y 1g. 1 is a side elevation of'a bowl, flush tank, and adjacent building parts, and show- 40 in my improved Ventilating system as applied thereto. v

Fig. 2 is a sectional detail elevation throu h a modified form of the device, showing t e app1 ication of a motor and fan to the ventilator flue.

Figi?, is a detail elevation, partly in section, showing a switch connection to the bowl cover for automatically starting and stopping the fan motor. l

Fig. 4 is a .diagram atie plan view of the 50 circult system employed with the fan motor.

Referring to the drawing more particularly and-.by reference characters, A designates any common and well known type of toilet bowl having a seat B and cover C, hingedly "secured as at D, said bowl being connected'to a water receptacle E by a flush pipe F, in the customary manner. I

To my knowled e ventilatlng and deodorant devices hereto ore applied to closet bowls oo.

have required the use of separate parts projecting into the bowl, or formed therein, which is objectionable chiefly because of the cost or because of the diiliculty of so securing` such parts that they will not be obstructive or in the way. To overcome these difficulties and at the same time to provide a simple and practical arrangement for ventilator communication with the bowl, I connect the lower endof the ventilator ilue 5 directly to the 70 flush pipe F, as at 6. Thus lthe lue 5 can in no way interfere with the function of the pipe F, and that pipe can in turn serve the double function above noted. The flue 5 has a damper 7, and extends with its upper end up through the ceiling of the building, where it may be provided, in its simplest form, with y a wind rotated metal hood or cowl8 to accelerate the updraft through the flue 5.

As'shown in Fig. 2 the flue 5 is provided with an enlarged, pear shaped housing 9, havin a cover 10 secured as by wing nuts 11. A small electric motor 12 is secured to the cover 10, and in turn carries a pair of propellers 13, which, when rotated, operate to create an updraft through the'lue 5. It will be noted that the housing 9 is secured tothe ends ofthe upper and lower flue sections 5 by hose connections 14 which are sufficiently flexible so that vibrations and noise of the through the switch 16, as by supply Wires 18.

In the modification shown in Fig. 3, the seat and cover ivot D anchors on a pair of vertically slida le posts 19 that are held in yieldably raised positions, as by springs 20,

- but when depressed will act as a switch memsion of the ving a seat ring 'and a v ber to close a circuit through the motor. The

cover C may be provided with a bracket rest 21, so that it will be impossible to close the switch 19 when' the cover C is closed, which 1s a desirable feature especially when it may come necessary to use the cover C as an ordinary seat or support for other purposes. Itis undel stood that suitable modifications may be made in the structure as disclosed,

provided such modifications come within thc spirit and scope of the appended claims.

aving now4 therefore fully illustrated and described my invention what I claim to be new and desire to protect by Letters Patent 1s:

1. The combination with a closet bowl having a seat ring and a cover therefor, of a depressible bearing member hingedly supporting the ring and cover, a ventilator for the bowl, means rendered operative by depression of the caring member when pressure is applied to the seat ring to actuate the ventilator, and means carried by the cover to lock the bearing member in its normally raised or inactive position when the cover is closed.

2. The combination Witha closet bowl having a seat ring and a cover therefor, of a depressible bearing member hingedly supporting the ring and cover, a ventilator for the means rendered operative by depresbearing member when pressure is applied to the seat ring to actuate the ventilator, and means rendered operative by closing the cover to lock the bearing member in its raised or inactve position.

8. The combination with a closet bowl havcover therefor, of a motor actuated ventilator for the bowl, a circuit for the motor, a. depressible member forming a hinge bearing for both the seat ring and the cover, a switch in the circuit arranged to be closed by depressing the bearing` member, and means rendered Adperat-ive by closing the cover to switch in its circuit opening position.

` 4. The combination with a closet bowl having a seat ring and a cover hinged with rerenderl the ventilator actuating means inactive.
