This invention relates to a ventilating apparatus for toilet bowls and particularly to a mechanism for controlling the operation of said apparatus.

The object of the invention is to provide a toilet bowl with a ventilating apparatus so associated therewith that if said bowl becomesclogged and the water therein rises above its usual level when the bowl is flushed 10 that said water will not interfere with'or submerge said apparatus.

Another object of the invention is to provide a novel mechanism for operating a switch' that controls-the operation of the electric motor which drives the suction pump, said mechanism operating automatically to close the electric circuit to said motor when the seat is depressed, and also to open said circuit when pressure upon said The invention consists in a ventilating a paratus for toilet bowls asset forth in t e following specification and partichlarly as pointed out in the claims thereof.

Referring tothe drawings':--

Figure 1 is a side elevation of a toilet bowl, a ventilating apparatus embodying my invfintion beingillustrated-associated therewit 30 Fig. 2 is a. plan view of a portion of the apparatus illustrated in Fig. 1, a portion of the cover for the toilet bowl being broken away to more clearly illustrate partslocated .therebeneath. 4 7 Fig. 8 is a detail vertical section taken on the line 33 of Fig. 2, the cover for the bowlbeing raised and the seat being illus. t'rated in its depressed position.

Like numerals. refer to like parts throughout the several view's'ofjthe drawings. In thedrawin'gs, 5 represents a'toilet bowl of well-known form, 6 a seat, and 7 a cover located above said seat. The seat 6has a cushion 8 attached to the undersurface therea of and so positioned relatively to the top edge of said bowl that when said seat is depressed said'cushion will tightly close any space that there may be between said seat and said bowl.

0 Rigidly fastened to the top surface of the bowl 5. adjacent to the rear'thereof, are a pairof similar brackets 9 in which. a rod 10 is mounted, and the latter constitutes a pivot for the cover 7-which is. connected. to said v 5 rod by a pair of arms 11. p The cover 7 has which are 7 15. The r0d15, therefore, constitutes a pivot 'nozzle is connected b V its.undersurface at the front thereof, and said cushion rests upon the front portion of the seat '6.- Pivotally mounted upon the rod 10vbetween the arms- 11 of the cover 7 is a rocker member 13, and the latter has a-pair of forwardly projecting arms 14 formed integral therewith in which the rod 15 is mounted. 1

A plate 16 is secured to the undersurface of the seat 6 adjacent tothe rear thereof, and said plate has a pair of rearwardly projecting arms 17 formed integral therewith. pivotally mounted upon the rod a cushion 12 secured to for the seat 6 and in its normal position said seatat the rear-thereof is raised, so that its cushion 8 is outof engagement, with the top edge of the bowl 5, except at the very front of said bowl. ,A-forked member 18 is connected to the opposite extremity of the rocker 13 from that to which the seat 6 is pivoted, and said forkedmember is connected by a weighted connecting rod 19 to a switch 20 hereinafter to be more fully described. The connecting rod 19 constitutes a weight and is sufliciently heavy to normally hold the seat 6 in the raised position illustrated in Fig. 1.

Resting upon the upper surface of the toilet bowl 5 at the rear thereof, with its" entrance positioned adjacent to the rear'of the seat 6, is a suction a vent pipe 22 with a suction pump 23 drlven by an electric motor 24. A discharge. pipe 25 leads from the nozzle 21, and said suction pump 23 to. any suitable location,

but preferably said pipe discharges into the open air.

The switch mechanism 20, previously mentioned, embodies therein a pair of electric contact m'embers'26 and 27',- both of which are mounted upon-an insulating block 28 mounted within a casing 29. The contact member 26 is connected by a wire 30 with the electric motor 24. The contact member 27 is connected by a wire 31 with a suitable source of electric supply 32 and the latter is i connected by a wire 33 with the motor 24. The weighted connecting rod. 19 is operatively connected with a lever 34 pivotal'ly mounted at 35- within 'the casing 29,,and

said lever has a push member 36 constructed i of insulating materialfas't thereto and adapted to engage the contact member;26 when said lever is rocked, thereby forc ng .10, thereby operating normal position said contact member into engagement with the contact member 27,. and completing the electric circuit through said members- Whenever the seat 6 is depressed, which happens whenever a person is seated thereon, the member 13 is rocked upon its pivot the lever 34 to complete the electric circuit at the switch 20 to the motor 24, and the immediate operation of the suction pump 23 causes the suction created to discharge the fumes from the toilet bowl. I

As soon as the pressure upon the seat 6 is removed, the weighted member 19 will immediately cause the seat 6 to return to its as illustrated in Fig. 1, at which time the electric circuit at the switch I 20 will be broken.

. rigidly connecting said seat The cover 7 is so mounted'upon the pivot 10 and rests in such a manner upon the front of the seat 6 that any pressure downwardly thereon, as by a person sitting upon said cover, will not the seat 6 other than to slightly compress the cushion 8 at the front of said seat.

It is evident that all of the mechanism hereinbefore described is so arranged with relation to the toilet bowl that if the latter in any way becomes clogged, so that in flushing the toilet the water therein rises above its accustomed level, that none of the parts of this mechanism will be submerged.

It is furthermore evident that'as there is no switch or electric wires either upon the seat or adjacent to the top of the toilet bowl that there will be no danger in the device of this invention of water splashing within the bowl causing short circuits in the electric switch or wires connecting thereto.

I claim 2- 1. In combination a toilet bowl, a vent pipe communicating therewith, a suction pump connected to said pipe, an electric motor for said pump, a switch for said motor, a seat for said bowl, and a weight and said switch, whereby the latter is operated by said seat to control the operation of said motor.

have any effect upon 2. In combination a toilet bowl, a vent pipe communicating therewith, a suction p connected to said pipe, an electric motor for said pum a switch for said motor, a seat for sai bowl, and means operatively connecting said seat with said switch, whereby the latter is operated in unison with said seat to control the operation of said motor, said means embodying therein a weight comprising a rigid connecting member and adapted to hold said seat in its normal position.

3. In combination, a toilet bowl, a vent pipe communicating therewith, a suction pump connected to said pipe, an electric motor for said pump, a switch for said motor, a rocker pivotally mounted upon said bowl, a seat for said bowl pivotally attached to said rocker, and a weight connected to said rocker and adapted to hold said seat in a raised position, said weight also being operatively connected to said switch, and comprising; a rigid connection between said rocker and switch, whereby the latter is operated in unison with said seat to control the operation of said motor.

4. In combination, a toilet bowl, a vent pipe communicating therewith, a su'etion pump connected to said pipe, an electric motor for said pump, a switch for said motor, a pair of brackets mounted upon said bowl, a pivot member in said brackets, a

rocker mounted upon said pivot members, a seat for said bowl pivotally attached to said rocker, a weight connected to said rocker and adapted to hold said seat in a raised position, said weight also being 'operatively connected to said switch and comprising a rigid connection between said rockerand switch, whereby the latter is operated in unison with said seat to control the operation of said motor, and a cover for said bowl also pivotally mounted upon said pivot members.

In testimony whereof I have hereunto set my hand.
