Patented Feb. 29, 1944 UNITED- STATES PAT ENT OFFICE V'ENTILATED CLOSE-T BOWL n Herbert' Wheeler, Springfield, Mo. i Application April 8, 1942, Serial No. 438,184 1 claim. (ci. 4 216) the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings Figure 1 is a perspective view of a portion of a toilet bowl equipped with the present improvement.

Figure 2 is a side elevation thereof.

Figure 3 is a section on line 3-3, Figure 2.

Figure 4 is a section on line 1 -4, Figure 3, but showing the exhaust pipe extended in a different direction.

Figure 5 is a front elevation of a modified form l of ventilated bowl.

Figure 6 is a section on line 6--6, Figure 5.

Figure l is a section similar to that shown in Figure 5 but illustrating a further modification.

Referring to the figures by characters of reference, I designates a closet bowl which, generally, can be of the usual configuration. The back portion of the top of the bowl has a flat rearward extension 2 carrying an integral shelf 3 on which the flush tank, not shown, can be mounted. A seat has been shown at 5 and is adapted to be connected in the usual way to the extension 2 by means of hinges 6 which, as ordinarily, hold the bottom surface of the seat spaced from the top surface of the bowl. It is into thisI space that the Ventilating means ccnstituting the present invention is adapted to open. In -order that the Ventilating means may be properly accommodated, the extension 2 is formed with a recess in its top surface as shown at 1, the shape of this recess corresponding with the shape of the intake head of the ventilator. In the form shown in Figures 1, 2 and 3, this l intake head is substantially T-shaped and includes a flat tube 8 of metal, or other suitable material the free end of which is open and ush with the corresponding inner surface of the bowl while the other end of this portion 8 opens into a rear laterally extended portion 9 the sides of which are provided with bottom outlets. Either of these outlets can be in the form of a pipe I0 leading to the point where the objectionable fumes are to be discharged or, if desired, leading to a small suction fan. If only one of these outlet lpipes I0 is used, the other outlet in the extension 9 can be in the form of a nipple II closed by a cap I2. With this arrangement the pipe I0 can be placed at either side of the bowl as might be found most convenient while the capped nipple can be placed at the other side.

The top surface of the Ventilating head is flat and the overall thickness o-f this head is such that when the head is seated in the recess "I, all portions of the top surface thereof will be below the level of the bottom surface of the seat 5 when in open or closed position. If preferred, and as shown in Figure 4, the outlet pipe I3 can be extended backwardly from one of the outlets of the Ventilating head so as to be inserted directly into a wall back of the bowl.

Under some conditions it might be advisable to eliminate the separate Ventilating head and, instead, to cast or otherwise form the head in one piece with the bowl. Such a modified form has been illustrated in Figures 5 and 6 wherein that portion of the bowl directly in front of the shelf I4 and corresponding with the extension 2, is formed of increased thickness as indicated at I5 so that its top surfacewill be of substantially the same level as would be the separate head 8 9, if used. In other words the top surface of this extension I5 will be close to but under the bottom surface of the seat when the seat is closed.

Formed in this Ventilating head formed by the extension 5 is the intake portion I6 opening towards the hopper and having its end fiush with the adjacent inner surface of said hopper.

This intake portion is much broader than its height, as will be `noted by referring te Figure 5 and it has a lateral extension I1 provided with an outlet I8 opening downwardly therefrom. A Ventilating pipe I 9 is adapted to be joined to this outlet as shown in Figure 6. If preferred, however, and as shown in Figure 7, the laterally extended portion 2U of the ventilator head can be located to open through one side of the extension 2 so that the fiattened end of a Ventilating pipe 2| can be fitted snugly thereinto. In this figure the intake portion has been indicated at 22, it being understood that the same is of substantially the same proportions as the intake portion I6 of the integral head shown in Figures 5 and 6.

It is to be understood that a closet bowl having an integral Ventilating head or an applied Ventilating head such as herein described Will carry off all objectionable odors after the ventilating pipe has been joined thereto and extended to a point of discharge. As before indicated this pipe can open into an exhaust ange should that be found desirable.

It will be noted that because of the peculiar construction and location of the intake portion of the Ventilating head, the usual mounting of the seat will not be interfered with nor will the appearance of the bowl be marred.

What is claimed is:

The combination with a closet bowl, said bowl having an extension at the back thereof with a recess in the top of the extension, and a seat hingedly mounted on the extension, said seat being spaced from the top surface of the bowl when the seat is open or closed, of a flat hollow Ventilating head mounted seated in the recess in the extension and positioned between the seat and the extension, said head including a flat broad intake portion seated mainly in the recess and having an inlet above and substantially ush with one of the inner surfaces of the bowl and having an outlet, and spaced tubular means for anchoring the head on the top surface of the extension, one of said means comprising a Ventilating pipe extended through a portion of the bowl and joined to and opening into the outlet and a closure for the other one of said means.
