6 Claims.

This invention, a toilet ventilator, is particularly designed to obliterate objectionable odors from and about toilet bowls by removal of odoriferous gases, and their discharge either into a vent pipe, or through a deodorant or fumigant.

The objects of the invention are as follows:

First; to provide means for automatically removing odoriferous gases from a toilet bowl while the seat is occupied, and discharge said gases to or through means nullifying their objectionable eflzects.

Second; to provide means as outlined which can be incorporated in new toilet bowls and seats.

Third; to provide detachable means as outlined, which can be applied to existing toilets.

Fourth; to provide means as outlined which is automatic in action, operating when the seat is depressed and made inoperative by release or raising of the seat.

Fifth; to provide means as outlined which is economically constructed, compact, and which, when applied to a toilet, may be located entirely out of the way back of the toilet bowl, and which does not interfere with normal functioning of the toilet.

Other objects and advantages of the invention will become apparent, as the following description is read on the drawing forming a part of this specification and in which similar reference characters are used to designate similar parts throughout the several views, of which:

Fig. 1 is a vertical sectional elevation through a toilet showing the invention applied thereto.

Fig. 2 is a section taken on line 2--2 of Fig. 1. 3 The usual toilet bowl has a trap l I which maintains a body of water l2 in the bowl, substantially to a level with the top i3 of the trap overflow,

' this trap discharging through the outlet H, the

base l5 of the bowl l6 resting on a floor H.

The upper end of the bowl is provided with a water distribution conduit l8, which communicates with the flushing conduit intake 19 at the back of the bowl, this intake I9 being in communication with a flushing valve or tank, (not 45 shown).

Mounted on the toilet bowl, as by hinges 20 is a seat 2| and a seat cover 22, the parts so far described not forming a part of the invention, per se.

The invention consists of a blower or fan having an impeller 23 mounted on the shaft 24 of an electric motor 25, this fan being enclosed in a housing 26 having an intake passage 21 and a discharge conduit 28, which discharge conduit may discharge to the outside of the room, to the usual vent pipe, (not shown), or through a deodorizer or fumigator 29.

A switch 39 having a plunger 48, cooperates with the seat hinge-plate 4|, closing a circuit through

wires

42 and 43 to the motor 25, when plug 44 is suitably connected to a source of current, a spring 45 normally maintaining the seat in partly raised position to maintain a broken circuit.

Sealing means 46, such as sponge rubber seals the space between the seat 2| and top 34 of bowl I6, permitting passage of gases only through the hole 41 in the seat about the person seated thereon.

The hinge connection consists of a pintle sleeve 84 operating on the hollow pintle 85, this pintle sleeve 84 being secured to the seat 2|. The lower leg 86 of the pintle sleeve has a central portion cut out to a point 81, and a diagonal passage 88 is formed through the rear portion of the seat 21 and opens into the toilet bowl within the seal ring 48, and communicates with the interior of the pintle, as shown.

The hollow pintles are formed integrally with the hinge standards or posts 80, which are also hollow, the flange 8i seating on the top 34 of the toilet bowl at its rear end and being secured by means of nuts 93. The intake conduits to the fan are threadedly secured to the lower ends of the posts or standards, as shown at 94.

The air or gas is drawn through the duct 88, thence through the

passages

96 and 95, pintles 85, standards 90 and conduit 94.

It will be understood that variations in construction and arrangement ofv parts, which variations are consistent with the appended claims, may be resorted to, without detracting from the spirit or scope of the invention, or sacrificing any of the advantages thereof.

I claim:

1. A toilet ventilator comprising a toilet seat, a hinge having a standard with integral pintle and a passage formed axially through said standard and said pintle, a pintle sleeve rotatable on said pintle and in communication therewith through radial passages formed in the pintle, said pintle sleeve communicating with the interior of a toilet and being attached to said seat, and exhaust means having a communicating connection with the terminal end of said standard and exhausting the toilet through said pintle sleeve, pintle and standard.

2. Exhaust means for a toilet having a seat comprising an exhaust fan having an intake, and a driving motor for said fan, and a seat hinge having hollow hinge standards with integral hollow pintle, and a pintle sleeve secured to said seat and forming a communicating connection between said standards and said toilet through said seat, and conduits connecting the terminal ends of said standards and the intake of said exhaust fan.

3. A communicating connection between exhaust means and a toilet for ventilating said toilet comprising a seat hinge having hollow standards with integral hollow, intercommunicating pintles, means for securing said standards to a toilet bowl, conduit-connection means formed on the terminal end of each standard, radial es formed in said pintles, a pintle sleeve having a passage in communication with said radial passages and secured to said toilet seat and having passages communicating between said pintle sleeve and the interior 01' said toilet bowl.

4. A hinge having a pintle and a standard supporting said pintle, a passage formed axially in said pintle and a passage formed axially in said standard, said passages terminating in communication one with the other and forming a communicating connection between exhaust means and means to be exhausted.

5. An exhaust connection between an exhaust fan having an intake and a toilet having a seat comprising a hinge having hollow standards and hollow pintles in intercommunication, a pintle sleeve having a passage in communication between said pintles' and said toilet through said seat, and communicating means connecting said intake with said standards.

6. A communicating passage between the. intake of an exhaust fan and a toilet having a seat, and a hinge for said seat having standards, pintles and pintle sleeve, comprising a passage formed axially through said standards and pintles, and a passage formed in said pintle sleeve and communicating with the passage in said pintles and with a passage formed in said seat and communicating with the interior of the toilet.
