WATER CLOSET Filed April 8, 1937 2 Sheets-Sheet 2 Inventor a J Weqpver Patented Nov. 23, 1937 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates broadly to water closets and has for its primary object to provide a closetwhich embodies therein means for exhausting gases and odors therefrom during the operation of flushing; and the invention together with its objects and advantages will be best understood from a study of the following description taken .n connection with the accompanying drawings wherein:

Figure 1 is an enlarged sectional view through a toilet room illustrating the invention.

Figure 2 is a vertical sectional view through a hopper provided with a ventilating opening in accordance with the present invention.

Figure 3 is a fragmentary elevational view of the flush tank illustrating certain details hereinafter more fully referred to.

Figure 4 is a fragmentary top plan view of the hopper also illustrating certain details herein- 20 after more fully referred to.

Referring to the drawings by reference numerals it will be seen that 5 indicates generally a toilet room, while 6 indicates the hopper and 1 indicates the flush tank.

In accordance with the present invention the connection between the flush tank I and the hopper 6 embodies what is known as a Siamese water outlet which includes a valve casing 8 on the top of which seats the control valve 9. Con- 30 nected with opposite sides of the valve 8 are fittings In that serve to connect the water outlet pipes H with the valve 8. Pipes I! extend downwardly from the flush tank and are connected as at l2 with water inlets l3 provided in the 5 hopper 6 so that two streams of water are directed into the hopper for flushing the latter.

Further in accordance with the present invention the hopper 6 at the back thereof and as clearly shown in Figure 2 is provided with a ven- 40 tilating opening I4 in which is fitted a nipple i5 provided at one end with a flange 16 that engages the inner face or wall of the bowl 6. At its outer or free end the nipple I5 is threaded to receive a jam nut N that is threaded home against the bowl 6 as shown in Figure 2.

Connected with the threaded end of the nipple I5 is an elbow l3 that extends through the wall l9 of the toilet room 5 and within the hollow of said wall is connected with one end of a ventilating pipe 20 that extends upwardly through the wall and through'the roof 2| as shown in Figure 1. On its upper outer end the ventilating pipe 20 is provided with a suitable cap 22.

It will thus be seen that during the flushing of the bowl 6 the odors and gases will pass from the bowl 6 through the ventilating nipple l5, elbow l8 and ventilating pipe 20 to the atmosphere.

Having thus described the invention what is claimed as new is:-

1. In a water closet, a hopper provided with a ventilating opening, a nipple having an end fitting within said opening, a flange on the inner end of the nipple, a nut threaded on the outer end of the nipple for drawing the flange against the inner wall of the hopper, and a ventilating pipe connected at one end thereof with said nipple.

2. In combination, a hopper, a flush tank therefor, a Siamese water connection between the flush tank and the hopper for flushing the latter, said hopper being provided with a ventilating opening between the Siamese water connections, a nipple having its end secured within said opening, an elbow connected atone end with said nipple, and a ventilating pipe connected at one end with said elbow.
