(Cl. 4-Z13) 9Claims.

This invention appertains to ventilated toilets, and is an improvement on my prior Patent No. 2,227,920, issued to me January 7, 1941.

One of the primary objects of my presentl invention is to generally simplify and reduce the cost of construction of ventilated toilets and to facilitate the installation and incorporation of my Ventilating system with toilets of the type now in common use.

Another salient object of my invention is to provide novel means for utilizing the protecting housing for 'the fan and motor as an entrance chamber for the foul odors from the toilet bowl, and to introduce the sucked-in air from the bowl into the housing insuch a way that the noise ofv the inrushing air will be reduced to a minimum, and the noise of the motor and fan will be muiiled.

Another important object of my invention is to provide positive means for preventing the drawing of ushing water into the `protecting housing with the sucked-in foul air from the bowl.

A further object of my invention is the provision of novel means for leading and forcing the foul odors or gases from the fan into a water seal ortrap chamber 'to prevent the escape of said gases in such a manner that the size of the water seal or trap chamber can be eectively reduced.

A still further object of my invention is to prol vide means for reducing noise and vibration in .f

the Ventilating system by the employance of a low speed electric motor, with means for rapidly driving the fan therefrom.

With theseVV and other .objects in view the invention consists inthe novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed,

Figure i4 is a detail, sectional view taken on the line Il-Il of Figure 12, illustrating the formation of the toilet to facilitate the insertion of the vent pipe of the Ventilating system therewith.

Referring to the drawings in detail, wherein similar` reference characters designate corresponding parts throughout the several views, the

letter T generally indicates my improved ventilated toilet, which comprises a toilet bowl l5 having communicating therewith throughv a water seal or trap I 6 a'drainpipe i1.

The upper end of the bowl il has formed therein a flush ring Il. Thisflush ring has communicating therewith a pluralityof outlet apertures Il,` and the flush ring' communicates with `chamber 21.

the main water loutlet20 .of the ush .tank 2|.

This 1outlet'20also communicates with an enthe level of the ushing waterrin the tank. In kaccordance with my invention, the overow pipe "isbent or has incorporated therein a U-shaped trap portion26 to `form a water seal, for a purpose which will be later set forth.

My device also yincludes a water seal or trap In one form of my invention, this waterseal or trap chamber 21 is made separate =from the bowl and tank, and with my present construction (as will be .later described), I am enabled to materially reduce the size of this chamber. Aszillustrated in Figures 1 and 2, the lwaterseal ortrap chamber 21 is arranged in back of thebowl and the outlet or drainpipe |1,and

is ,secured in ,placeby means of a bracket 28.

'Communicating with thechamber 21 is a combined water supply and foul odordelivery pipe 29.

The lower endof `this pipe 23 is bent to form a water trap 30,and the pipe is extended into the trap chamber supply `above the normal water level therein. The pipebelowthe water level has formed therein a small water inlet opening 3|,

whereby to insure the correct supplyof water to the trap 30 to .maintain'the seal. Likewise, extending into thetrapchamber 21 above the water level and above the upper end of the pipe29 is a foul odor drawoif `pipe 32. This pipe isextended into the. drainpipe'H in rear of the water seal I6 for the bowl. Anypre'ferred type of coupling 32' can be employed for connecting the pipe 32 with :the toilet. vThe drawoft pipe also has formed therein a small drain opening 33 adjacent the water levelin the trap chamber, and, hence, this opening 33'acts to prevent the water from rising Vabove a predetermined normal level in :said 4trap chamber. I

. Inthe flush tankV 2 l, I secure aprotectinghous- ,-ingvor casing 34 for the electric motor 35.and the yian 36. The rotor of the fan is drivenfrom the armature shaft ofthe motor, and ahousing l31 vis vemployed for surrounding ithe motor. The motor-and fan are suspended in the protecting housing or casing 34 by `means of cushioning springs 38, which vare placed at the desired advantageous points. The housing 31 for the motor is `formed fromicopper or other material which will `quickly `transmit .or .dissipate heat, so that :this housing v31will not become unduly heated from theelectric motor 35.

The'pipe 29 is connected to the outlet of the Ian'by theuse ofa suitable flexible coupling, and :the inlet of the fan is adapted to draw air in from the'housing or casing 34 and to force the air vthrough the pipe L29 into the trap chamber 21. This pipe 29 hascommunicating therewith adjacent the bottom .of lthe flush tank 29 the water seal rell tube 39. This tube extends into the water refill pipe 40 for the ilush tank. The tube 39 .is provided with .an air inlet opening 4| at a point above the normal Water level in the Yflush tank, and this opening is provided for Vbreaking any siphoning action which might take place in said tube. By. this arrangement of parts, the pipe 29, as heretofore stated, is ,utilized both for supplying water to the trap chamber 21 and for conducting the foul odors to said trap chamber. Communicating with the top of the .trap 26 in the overow pipe 25 of the flush tank is the foul odor suction pipe 42. .This suction pipe 42 extends into the bottom of a supplementary foul odor chamber 43, and the upper` end of the chamber communicates with the housing or casing 34 by means of a plurality of small openings 44.

When the fan is in operation, foul odors will be drawn through the flush ring I8, through the opening 20, the overiiow passageway 24, pipe 25, suction tube 42, supplementary chamber A"43, into the housing 34, and into the fan. As the suction'tube is above the .trap chamber, little or no vwater will be drawn into the supplementary chamber. 43 with the air, and'this chamber functions to collect such ywater and to allow the water to drain back into the overiiowpipe. The plurality of openings 44 distributes theA inrushing air and materially reduces vthe noise incident to the Ilow of air passing through the fan 36. The housing 34 and the chamber 43 also serve as a mufller for reducing noise produced rbythe fan and motor. If desired, the inner face of the housing or casing 34 can be `provided with a r.lining or skin of -soundprooiing material 45, as

shown in Figure 5 of the drawings. The pipe 29 Vat a desired point in the housing can be provided with a water drain opening 29' to prevent the collection of any water which might be present in the housing 34.

In use of my toilet, the circuit through the motor 35 is closed by the use ofa suitable switch mechanism, which is operated preferably by the weight of a person using-the toilet. Asstated, upon the operation of the motor, the fan will suck in air and Vfoul odors from the bowl, 'and this air is forced through the pipe 29, into the ktrap chamber 21, and the water inthe trap 3U `provided for resealing the trap 30 with water without the necessity of ilushing thebowl l5, as water will enter the trap through the opening 3| .from the water supply in the `reservoir `21.

If preferred, water can be supplied to the pipe 29 by means of aninverted U-shaped tube 46 (see "Figures 7, 8, and 9) in lieu of the tube 39. This tube 46 terminates adjacent the bottom of the ush tank, and any siphoning action inisaid tube 46 will be broken by an `air inlet tube 41, which communicateswith the upper bend in said tube, and which extends above the normal wa- 50 is placed over the inlet of the tube 46 in spaced relation to the partition 48. During the intake of water from the tube 45 by the pipe 29, the screen will prevent the entrance of sand and the like into saiciV tube, and when the bowl is flushed, the rushing of the water from the flushing tank and the 'drawing of any water inthe tube will clean and wash the screen l0..

While I preferto utilize a high speed electric motor and to reduce noise and vibration by employing cushioning springs, as shown in Figures land 2, noise can be reduced to a limited extent by employing a low speed electric motor, and con-` necting the motor with the fan through a speed increasing mechanism.

In Figures and ll, I have shown a protecting housing 5I for a. motor 52 and a fan 53, and this housing is adapted to be disposed in the flush tankin the same manner as the protecting housing 34. The motor 52 is of the low speed type and is secured directly to the housing 5| The fan 53 is'held in spacedrelation to the motor by brackets 54. The armature shaft of the motor has connected therewith a drive pulley 55 of a relatively large diameter, andfthis pulley has trained about the same a drive belt 56. The drive beit is, in tum, trained over a relatively small pulley wheel 5l` secured to the drive shaft oi' the 'y rotor o! the tan.y

In,Figures l2 to l4, inclusive, I have-illustrated` a means for forming the trap or'water seal chamber for the foul odors directly with the toilet. The rear of the toilet bowl has connected therewith a chamber 58, and this chamber communicates with the drainpipe I1 through the medium of an opening 59 in the lower end thereof. A water receiving compartment 60`open at its top is arranged in the chamber 58. The conduit pipe 29ffrom the fan is led into the compartment 65, and this conduit pipe, at 'its lower end, in this form of the invention, is provided witha U-belt 62. The upper end of the U-belt extends above the water compartment 50 and is provided with a small opening 63 below the normal water level in said compartment for insuring the maintenance of the water seal in said U-belt. The water compartment Alill acts as a reservoir for supplying water through the opening ,63l to the water seal in the U-shaped portion 62 of the pipe 29; I-t can be seen that the foul odors andv air will be forced through the pipe 29 directly into the compartment Bland then in the drainpipe I1 through the opening 59. The opening '54 (see Figure 14) for the trap 52 can be of an elongatedcharacter, so as to fa'- cilitate the introduction of the trap into the water reservoir 50, and` this opening 83 can be closed by the use of gaskets and the like.
