' 13 Claims. (01. 4-215) This invention relates to improvements in ventilating toilets. 1

The general object of this invention is to provide a novel toilet embodying novel forced draft means for conveying obnoxious odors therefrom.

Another object of my invention is to provide a novel forced draft ventilating system for toilets.

Another object is to provide a novel toilet ventilating means which is entirely automatic in 1 operation.

A further object is ,to provide a novel toilet ventilating valve mechanism operated by applying weight to the seat.

Another object of the invention is to provide a novel toilet ventilating apparatus wherein the parts are all mounted within the-toilet bowl and wherein the parts can be economically made and installed.

An additional object of my invention is to provide novel forced draft ventilating means for a toilet bowl which is free from clogging and other troubles and which will operate satisfactorily, without need for servicing or attention, over long periods of time. p

Other objects and advantages of my invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:

Fig. l is a top plan view, with parts broken away, showing a ventilated toilet embodying the features of my invention;

Fig. 2 is a section taken approximately on line 2--2 Fig. l;

Fig. 3 is a section taken on line 3-3 Fig. l;

Fig. 4 is a section taken on line 4-4 1;

Fig. 5 is an enlarged fragmentary top plan view with parts broken away showing the seat mountin Fig. 6 is an enlarged vertical section through the valve .mechanism with parts broken away;

Fig. 7 is an enlarged fragmentary side elevation of the valve mechanism shown in another position with-parts broken away;

Fig. 8 is an enlarged vertical section of the The toilet bowl ll includes a base l4 and walls 55 I5 defining the usual internal chamber l8 having a lower water trap II which communicates with the usual waste pipe outlet I8.

The upper end of the bowl ii is provided with the usual rim l9 having an internal annular water chamber 20 from which water is discharged 5 through a plurality of apertures 2|. The internal chamber 20 communicates with the flush tank 12 through a conduit 22 and pipe 23.

Water is supplied to the flush tank by means of a conduit 24 which includes a valve 25, a T 10 member 26, and a suitable coupling 21 for securing the conduit to the flush tank l2.

The valve mechanism l3 comprises a cylindrical body portion 28 having a central bore 29 which is open at the lower end as at 30 and internally 15 threaded at the upper end as at 3| to receive a threaded closure member 32 which includes a packing ring 33.

Approximately midway between the upper and lower end of the central bore 29 an annular boss 20 34 provides a shoulder 35, the lower side of which is bevelled outwardly as at 36. A nozzle 3! threadedly engages the bore 29 as at 38 and secures a packing ring 39 against the shoulder 35. The nozzle 31 (see Fig. 8) includes a body portion 40 25 having a centrally arranged upright boss 4| in which a slot 42 is provided in which a screw driver may be inserted. The nozzle 31 includes apertures 43 in the lower end of the boss 4| which intersect an axial aperture 44 extending downwardly into a cylindrical chamber 45 in the body portion 40.

Directly below the nozzle 31 and shoulder 35 a plurality of apertures 46 are provided in the body 28. These apertures communicate with the exterior of the valve l3 and the ends are outwardly bevelled as at 41 thus providing a more evenly distributed flow of air.

The lower end of the cylindrical body portion 28 is provided with externally threaded portions 40 48 and 49 to receive clamping nuts 50 and 5| and gaskets 52 and 53. The upper end of the body portion 28 has an enlarged head portion 54 from which opposed bosses 55 and 56 project. A shoulder 51 is arranged above the bosses 55 and 45 5B. A bevelled portion 5'! is disposed below the bosses and is engaged by a gasket 51".

A bracket 58 having a central bore 59 engages the enlarged head portion 54 and is secured thereon and against the shoulder 51 by a nut 60 which 50 engages threads 6| on the enlarged head portion 54.

The boss 55 includes a central bore 62 having a reduced bore 63 at the inner end which is bevelled to provide a seat against which a 55 valve 64 is normally held closed by a spring 65. The spring 65 isheld compressed by a coupling 66 threadedly secured to the boss 55 as at 61. The coupling 86 includes a central bore 68 having an enlarged outer bore 69 in which a conduit I0 is secured in place by a packing nut II and packing l2 and has its outer end connected to a valve I3 which is in turn connected to the T member 26 by a conduit 14 thereby supplying water to the valve I3.

The valve '64 includes a valve rod I5 having a reduced portion I6. The valve rod I5 extends across the bore 29 into a central bore 'I'I in the opposed boss 56 and outthrough a packing nut I8 which secures suitable packing I9 in an enlarged bore in the outer end of the bore TI.

The valve I3 is mounted within an aperture 8| in the rear and at one side of the toilet bowl H and is secured in position by the nuts 50 and 5I and is maintained against leakage by the gaskets 52, 53 and 5I-. A lateral opening 82 is provided whereby the nuts 50 and 5| may be easily reached. The nut 5| secures the lower end of the valve within a conduit83 which is in alignment with the aperture 8|. The conduit 83 extends down within the water held in a trap 84 by a dam 85 integral with the walls l5. The dam provides a channel 86 in front of the dam 85 and an aperture 81 at the lower end cannects the channel with the waste pipe outlet l8.

The bracket 58 has an enlarged head 88 with an aperture 89 therein which pivotally supports one end of a shaft 90. The other end of the shaft 90 is supported in an aperture on a bracket 9i secured to the toilet bowl II at the rear and at one side as at 92. The outer ends of the shaft are provided with square shanks 93 on which is mounted shackles 94 and 95 secured in place by nuts 96. The opposite end of the shackles 94 and 95 engage square shanks 91 on the end of a second shaft 98 which extend through the rear end of the seat 99 and are secured in place by nuts I00. Thesquare shanks' on the ends of the shafts are to eliminate any tendency for the seat to twist when. weight is applied. A seat cover I0! is pivotally mounted on the shaft 90 by means of brackets I02. The

shackle 95 includes a downwardly projecting cam 95' which is in alignment with the endof the valve rod '55,

The front of the seat cover i0! is provided I, with a rubber bumper I03 directly over a rubber bumper I04 on the seat99. The bumper I08 engages the top of the toilet bowl II. A second rubber bumper I05 on the rear of the 'seat 99 is a shorter than the bumper I00 and only contacts the toilet bowl II when weight is. applied to the seat. Y

When the valve i3 is securely held in place the apertures 46 in the cylindrical body 28 are in alignment with a chamber I06 which communicates with the chamber I6 by means of a .conduit I06 just above'the normal water level I06" of the bowl. A curvedboss 101 is provided on the toilet bowl directly in front of the lower end of the conduit I06 to provide a more gradually inclined inlet for the gas to enter the conduitl06'. An air bleed hole I08 is provided below the rim I9 of the toilet bowl H to prevent flushing water being drawn .into the valve device I3 when the toilet is flushed and the water level I06 rises and covers the entrance to chamber I06. A groove I09 is provided directly below the boss 56 and its component parts-to catch any water that may drip amasec mally open and the seat cover I0l may be raised 5 in the usual manner and upon applying weight to the seat 99, the cam 95 on the shackle 95' rocks about the shaft 90 and opens the valve 68 allowing water to pass through into the bore 29 thence downwardly to the nozzle 3'! and into 10 the apertures 43 wherein the water coming from both sides at high velocity meets in head on collision which causes a maximum of turbulence breaking up the fluid into fine globules. The

' water emerges from the nozzle in the form of 15 high velocity, uniform spray which is directed longitudinally and centrally through the bore 29. As the water emerges from the aperture 88 and passes the apertures 46 in the body 28 a partial vacuum is produced thereby causing a rush of air through the apertures 86 and causing obnoxious gases to be drawn from within the toilet bowl ll up through the chamber N6 and into the bore 29, thence down through the conduit 83, whence it bubbles up through the 25 water in the trap 84 and over the dam 85 and through the channel 86 and aperture 87 in the waste outlet pipe I8. Also the spray from the nozzle 31 condenses and supplies the water for the trap 84, the surplus escaping over the dam 30 35 Having thus described my invention I claim:
