This device includes a case use, causing a continual draft through the closet 3E which is provided with a passageway 3l extend and consequent loss of heat. The present inven tion overcomes this difñculty by providing a water 55 ing through the same from end to end. One end of the passageway 3l is threaded as designated closet in which the air outlet to the stack is closed at 38, to receive an end of a large nipple .39, the when the water closet is not in use. 2,409,048 3 4 other end 4| of which is screwed into the stack to open position.

A valve head 45, said case. It will readily become comprehended mounted on a valve stem 46, is slidable within that when the valve 58 is opened to cause the the passageway 31 to engage said seat 44 and obstruct the flow of gases through the passage 15 flow of water into the Ventilating device 35, that part of the water flows through the passageway way 31 or to move away from said seat suffi 82 and into the space 88 and forces the diaphragm ciently to uncover the holes 42 and allow the 1I into the depression 18.

At the same time, water Extending across the passageway 31 and adja is forced through the nozzle 49 and flow of air is cent the end of the case 36 in which the threads induced in the nipple 39 which draws the gases 38 are formed is a bridge or divider 41 which is from the bowl II and discharges the same into best shown in detail in Fig. 5. This bridge has stack I1. When the valve 58 is closed, the pres issuing outwardly from it a boss 48 which is sure of water in the space 88 is cut off and the threaded to receive a nozzle 49. Nozzle 49 is pro spring 19 gradually moves the valve 45 toward vided with a discharge opening 5| which is di the seat 44.

A tube The hinge structure I6, previously referred to, connection 54 is screwed into the case 35 and has includes two brackets 83 which are attached to the bowl II at the rearward portion of the rim- I3 attached to it a tube 55 which communicates with the passageway 53. The tube 55, as shown in 35 thereof. A pintle 84 extends through these brack Fig. l, is connected to another tube connection ets. Mounted on the pintle 84 are pairs of arms 56, which, in turn, is connected to an elbow 51. 85 and 86 which are attached to the seat I4 and Elbow `51 is connected toI a valve 58, which, in the cover I5, respectively. By means of these turn, is connected through a nipple 59 with a arms, the seat and cover may swing from open T 6I connected in water pipe 34.

This with a hub 81 through which the pintle 84 ex induces a flow of air through the passageway 31 tends. This hub is held immovable relative to the when the valve 45 is in open position and draws 45 pintle 84 by means of a set screw 88, illustrated in air from the interior of the bowl II through the detail in Fig. 2.

The valve stem 46 of valve 45 is guided for axial move 55 which the pintle 84 extends. This hub is rotat able on the pintle 84 and is held in position on the ment in a guide 68 which is screwed into the cen end of the pintle by means of a collar 94 which is ter of the block 65. A stufñng box 69, associated secured to the end of said pintle by means of a set with the guide 68, prevents leakage past said screw 95. `The arm 92 is connected by means of guide. The end of the valve stem 46 extends beyond the guide 68 and passes through a dia 60 a link 96 with an arm 91 which operates the valve 58.

The valve 58 is maintained in clos end of the stem 46. In this manner, the dia - 66 which pass through a flange 61 formed on said phragm 1I is rigidly attached to the stem 46. The outer edge of the diaphragm 1| is clamped in position between the outer marginal portion ing position by means of a tension coil spring 98 which is attached to an arm 99 movable with the valve member of said valve and which spring is of the block 65 and a cap 16 which overlies said 70 also attached to the water pipe 34. This spring, in addition to urging the valve 58 into closing po block and which is secured thereto by means of sition, also serves to hold the seat I 4 above its screws 11. Screws 11 extend through the cap 16 lower position, as shown in Fig. l, by a construc and are threaded into the block 65. The cap 16 tion now to be described. has a conical'depression 18 in it in which the dia phragm 1I is received when the valve 45 is moved 75 Formed on the collar 89 of arm 85 is a lug I8I n 2,409,048 6 having a shoulder Iû2.
