This invention relates to a Ventilating apparatus and is designed primarily for use in connection with toilet bowls, but it is to be understood that a Ventilating apparatus in accordance with this invention may be employed in any connection for which it may be found applicable.
The invention has for its objects to provide, in a manner as hereinafter set forth a Ventilating apparatus for quickly and thoroughly removing unpleasant odors from a toilet bowl.
A further object of the invention is to provide, in a manner as hereinafter Vset forth, a ventilatingapparatus for association with a toilet bowl and including means to provide an up-draft to quickly and thoroughly remove unpleasant odors from the bowl.
A further object of the invention is to provide, in a manner as hereinafter set forth a Ventilating apparatus for attachment to a toilet bowl and including a means controlled by the user of the bowl for creating an up-draft for the purpose of thoroughly conveying off unpleasant odors from Within the bowl.
Further objects of the invention are to provide,
in a manner as hereinafter set forth, an apparatus for the purpose referred to which is comparatively simple in its construction and arrangement, strong, durable, compact, readily installed in respect to a toilet bowl, thoroughly enicient in its use, conveniently repaired when occasion requires and comparatively inexpensive to manu facture.
With the foregoing and other objects in View the invention consists of a novel construction 5 combination and arrangement of parts, as will be more fully described and as are illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood than changes, variations and modications may be resorted to which fall within the scope of the invention as claimed.
In the drawing:
Figure 1 is a side elevation of the apparatus,
partly in section showing the installation thereof with respect to a toilet bowl and the wall of a building,
Figure 2 is a sectional and Figure 3 is a section on line 3 3, Figure 1.
Referring to the drawing I indicates the wall of a building, 2 a toilet bowl, 3 a flushing water pipe and 4 the seat for the bowl 2. The seat 4 is hinged, as at 5 to a pair of spaced parallel vertical posts 6 extending upwardly from the rear plan of the apparatus,
of the top of the bowl 2. The seat 4 is elevated with respect to the top of the bowl 2.
The apparatus includes a resilient strip 'l bent to conform substantially to the shape of the top of the bowl 2. The ends 8 of the strip l are arranged in parallel spaced relation and positioned upon the rear end of the top of the bowl. The remaining part of the strip I is positioned upon the sides and front of the top of the bowl. The outer portion of the strip l, centrally thereof is formed with a vertical opening 9 for the reception of a coil spring I0. The strip l acts to main tain the seat 4 in spaced relation to the top of the bowl 2 and also constitutes a support for the seat when the bowl 2 is used. The seat 4 is hinged with the post 6 in a manner whereby en the' application of pressure thereto, it will move in The apparatus includes a vent flue I2 of zigzag form for the purpose of offsetting it relative to the flushing water pipe 3. The forward end I3 of the flue I2 is olfset with respect to the rear end I4 of the latter. The forward end of the Hue I 2 is of greater length than the end i4 and it is seated upon the rear part of the upper face of the bowl 2. The forward and rear ends I3, I4
the bowl by the strip 'l air is prevented from entering into the bowl between the seat and the bowl.
The apparatus includes a closed receptacle I5 which is secured to the wall I and forms an air heating chamber I I5. An insulating covering I1 is mounted upon the top and sides of receptacle I5. The front wall of the receptacle I5, near its upper end has a rectangular opening I8 for the passage into the chamber I5 of the end of the iiue I2. Arranged within the chamber I6 is an electrical heater I9 anchored to and extending inwardly from one of the side walls of the receptacle I5. Heating circuit connections 20, 2| and 22 are provided for the heater I9. The connection 2U leads from a push button switch 23 to a terminal 24. The connection 22 leads from a terminal 25 to a terminal 26 provided with a contact 21. The terminal 26 and contact 21 are carried by a plate 28. A resilient arm is indicated at 29, which opposes and is spaced from the plate 28. The arm 29 is of greater length and the branch pipe B.
2. projects from the outer end of the plate 28. The plate 28 and arm 29 are anchored by the holdfast means 30 to the bottom of the receptacle I5. The plate 28 is insulated from the receptacle l5. The arm 29 is insulated from the plate 28. The arm 29 carries a binding post 3l and a contact 32. The connection 2l leads from the post 3| to the switch 23. The contacts 2l and 32 are normally spaced from each other whereby the heating circuit is open. When the contacts 2l and 32 are brought into an engagement the heating circuit is closed. The arm 29 is shiftable relatively to the plate 28 for the purpose of bringing the contacts 2l, 32 into engagement for the purpose of closing the heating circuit to make the heater i9 active whereby the air in chamber I6 is heated and will provide for an up-draft to cause the unpleasant odors to be withdrawn from the bowl. The heating circuit is not closed unless the bowl 2 is used, and when the bowl is used a means is employed to shift the extended portion of the arm Z9 upwardly to bring contact 32 into engagement with contact 2l. The means for shifting arm 29 consists of a circuit closing'member 3i which is interposed between the strip l and the seat d at the rear of the latter. The member 3l is so curved that when the forward portion thereof is lowered the rear portion thereof will be elevated and move the arm 29 to circuit closing position. The extended portion of the arm 29 is arranged in the path of the rear end of the member 3l. A fulcrum 32 is provided fo-r the member Si, and which is extended laterally from one side of the end i3 of the flue l2.
The apparatus includes a vent pipe se having a reduced extension Sii projecting through the rear wall of the receptacle i5 into the chamber l whereby communication is established between chamber l@ and the vent pipe 33. The extension 36 aligns with the end iid of the flue l2. The extension 3 is of a width less than the width of pipe 33. The latter is mounted in the wall l and are extend-ed above the top thereof. Mounted upon the top of the wall i and encompassing the upper end of the pipe 33 is a pipe branch 35 forming a continuation of the pipe 33. The branch 35 is provided with superposed diametrically disposed combined anchoring and supporting elements 3E, 3l. rihe element 'all' seats upon the upper end of the pipe 33.
The apparatus includes a revoluble cowl 3S provided at its lower end with an apron 39 which encompasses in spaced relation the upper end of The cowl 38 is of cylindrical form and provided at one side with an outlet opening 39. The cowl 38 has extending radially therefrom a vane d acted upon by the wind for the purpose of revolving the cowl 38. Arranged within the cowl 38 and above the skirt 39, and below the opening 39 is a diametrically disposed rod il provided with a bearing member ft2. Secured against the inner face of the top i3 of the cowl 38, centrally thereof is a bearing block Q4. Mounted in the block extending through the bearing "i2 and anchored to the elements 35, 3l is a vertically disposed stationary shaft i5 about which the cowl 38 revolves. The shaft also constitutes a sustaining post for the cowl 3S.
Although the chamber I6 is shown, by way of example as being heated by an electrical heater element for the purpose of creating an up-draft, yet it is to be understood that Various types of heating means may be employed for such purpose.

l. In a Ventilating apparatus for toilet bowls, a horizontally disposed flue adapted to have one end communicate with the bowl, a horizontally disposed receptacle constituting an air heated chamber communicating at its front with the other end of said flue, an electric heating element arranged within said chamber, a vertically disposed outlet iiue opening at its lower end into the rear of said chamber, a heating circuit'having interposed therein a pair of superposed contacts normally in spaced relation for normally opening said circuit, said contacts being supported from said receptacle and one being resilient, and shiftable means for moving the resilient contact to engage the other contact for closing the heating circuit.
2. The invention as set forth in claim l having said flues opening into the upper portion of said chamber and said heating element arranged in the lower portion and extending transversely of said chamber.
