1 Claim. (o1. 4-213) This invention relates to toilet ventilators and the tank controls the flow of the water from the has for its principal object to provide a simple tank. The construction of the water closet so and eflicient ventilating system of inexpensive far described maybe any one of this type of construction for toilet bowls with which all odors closets now in use and my ventilating system is 5 from the toilet bowl are effectively evacuated esconstructed so as to be readily and easily ap- 5 pecially during its use in order to prevent the pllcable to all of them to prevent the escape of escape of such odors into the toilet room thereby unpleasant and harmful odors during the use eliminating the annoyance and unhealthfulness of the closet. incidental to the use of toilets in the house. This ventilating system is inexpensive to in- Another object of this invention is to provide a stall and comprises the air intake manifold Ill 10 ventilating. system thatis easy and inexpensive which is formed up of sheet metal in the form to install. of a substantially narrow flat tube which is closed A further object of this invention is to provide at one end and has its other end terminate into the intake of the ventilating system with a sima tubular extension ll of cylindrical cross secple and easy mode of attachment to the bowl of tion. One side of the manifold is provided with 15 the closet. the elongated inlet thru which the air is drawn This and other objects and attendant advanfrom the inside of the bowl as will hereinafter be tages of this invention will become more readily described. The other side of the intake maniapparent from the detailed description thereof fold In is provided with the mounting flange I3 whichfollows, reference being had to the acwhich is suitably fastened to the anchoring bar 20 companying drawing in which M. The latter is provided with a pair of verti- Figure 1 isa front elevation of a water closet cal holes 5A, 5A which are spaced'so as to correequipped with my novel ventilating system. spond with the spacing of the bolts 5, 5 on the Figure 2 is a side elevation thereof. top of the rear of the bowl. In this way the bolts Figure 3 is a detail sectional view of a modi- 5, 5 are adapted to pass thru the anchoring bar 25 fied form of ventilating fan and its connection to have the nuts l5 clamp the anchoring bar for use with the ventilating system. to the top of the back of the bowl below the Figure 4 is a partial top plan view of thewater hinge of the seat and the cover thereof. closet bowl with the ventilating system mounted With the anchoring bar I fastened in place thereon. in. the manner above described, the intake mani- 30 Figure 5 is an enlarged detail sectional view of fold is held supported'so as to project from the the rear portion of the water closet bowl and the outside of the bowl over the edge thereof and ventilating system attached thereto. extend over the inside along the rear of the bowl Figure '6 is a horizontal section of the intake between it and the rear of the seat 2. The inlet 7 manifold of the ventilating system including its I2 is thus located over the inside of the bowl sub- 35 means for attachment to the water closet bowl. stantially the full length of the ma? thereof to Figure 7 is an enlargedvertical sectional view provide a large intake opening for a quick and of a water closet bowl in which the intake manieffective evacuation of the air within the bowl.
fold for the ventilating system is embodied in The intake manifold is connected to a. suit- 40 the bowl proper. able exhaust fan which is operated by an electric 40 In the several figures of the drawing like refermotor that is controlled by a switch which is ence numerals indicate like parts. preferably operated by.the cover of the closet The ventilating system forming the subject bowl. For this purpose a pipe line I6 is conmatter of this invention isillustrated in the nected to the cylindrically tubular open end of 5 drawing as applied to a water closet having the the intake manifold Ill, which pipe line leads to bowl I, a seat 2 on top of the bowl and a cover 3 the exhaust fan l1 and from the exhaust fan to extending over the opening in the'seat. The seat, any point where the odor of the evacuated air and the cover are hingedly mounted at the back will not be objectionable. Such a pointmay be of the bowl on the horizontal pivot shaft l which the roof of the house or the soil pipe of the sewer is supported by the spaced bolts 5, 5 which are system etc. 50 suitably anchored in the top of the rearof the In the form of exhaust fan l'l illustrated in bowl I. At the back of the bowl is located the Figure 1 the air enters the center of its circular water tank 6, and the pipe] connects the botcasing and is forced out by the blades tangentially tom of this water tank with the bowlfor flushing to the circular outer wall thereof. In the form of purposes. A suitable handle 8 on the outside of exhaust fan I'IA illustrated in Figure 3, the fan 55 20 for connection with the pipe line ii. If
enough natural draft is present in the pipe line l6 for the evacuation of the air from the closet bowl,
an exhaust fan may be dispensed with and a suitable length of pipe line is then used to take the place of the fan casing.
The exhaust fanis electrically driven and to make the operation of the fan most effective it is controlled by a switch that is automatically operated by the cover 3 of the closet bowl. When this cover is raised to uncover the opening in the seat just prior to the use of the closet, the fan is started to exhaust the air from the bowl while the closet is being used and kept on operating until the cover is closed over the seat after the closet has been used. This makes certain that all of the foul air is withdrawn from the bowl before the exhaust fan is stopped. Of course some ventilation continually takes place even after the exhaust fan has stopped because of the natural {draft in the pipe line.
For the automatic operation of the fan a switch 2| is mounted on top of a bracket 22 which is supported from the anchoring bar I so as to lo- ,cate the switch in a position in which the projecting push rod 23 of the switch is contacted by the cover when the cover is swung open to rest against the tank 01' the closet. Thepush rod 23 is spring pressed and when the cover makes contact with it, it is forced into the switch housing tohave the contact member 24 close the electric motor circuit between the terminal contacts 25 and 26. with the cover open and leaning against the water tank, the electric circuit of the" fan motor is thus 'held closed-so as operate the fan.
As soon, however, as the cover is being closed over the closet seat and swung'away from the to continually tank, the push rod-23 is released by the cover and moves out of the switch casing tov cause the connecting member 24 to open the electric circuit between the terminal contacts 25 and 26 and thus stop the fan.
In Figure 7 I have illustrated the intake for the ventilating system embodied in the bowl construction proper. In this construction the manifold 21 is cast into the bowl as an integral part thereof so as to have its mouth 28 on the inside wall below the top of the bowl. An opening 29, which may be slightly tapered, leads into the intake manifold from the outside of the bowl and is adapted to have the end 30 of the pipe line 16 extend thereinto for connection therewith.
I claim:
A ventilating system for closets comprising in combination a bowl, a seat, a cover over the seat,
anchoring bolts projecting from the top of the back of the bowl, said bolts carrying a hinge element secured to the cover to cause said cover to swing on said bolts, an intake manifold supported on said bowl by said anchoring bolts, a pipe line connected to said intake manifold, an exhaust fan connected to said pipe line, an electric motor for,
operating said exhaust fan, a switch for controlling the operation of said electric motor, a bracket carried by said manifold for supporting said switch above and to the rear of the cover of said' closet in cooperative relationship with said hinge element so as to determine precise contact between the cover and said switch for the operation of the exhaust fan when said cover is swung into a substantially vertical position in preparing the closet for use and operate the switch to stop thevoperation of the exhaust fan when placing the cover over the seat of the bowl after the use of the closet.
