This invention relates to improvements in toilet bowls, an object being to provide means for carrying off offensiveodors at the time of or after the use of the bowl, means being be hereinafter more fully described, illus-Y trated in the accompanying drawings and 75 pointed out in the appended claims.

In the drawings.: I

Figure 1 is a fragmentary sectional view.

illustrating the invention, the bowl and ventilator being closed. Figure 2 is a plan View of the bowl with the .cover and cover connection in section.

Figure 3 is an similar view showing the seat closed with the arms of the cover shown in section. 1 Figure 4 is. a fragmentary view similar to Figure 1 with the cover raised and the venti- I the length of the valve seat and sleeve valve,

lator open.

Figure 5 is a like view showing the seat raised and the scat ventilator closed.

Figure 6 is an enlarged fragmentary section on the line 66 of Figure, 2, with the bowl ventilator open.

Figure 7 is a similar view showing the bowl ventilator closed.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a portion of a toilet bowl which is provided around the opposite sides of its upper edge with a ventilating passage 11 having openings 12 providing communication between the passage and bowl. The passage extends rearwardly as indicated at 13 and communicates with an outlet passage 14 which may in turn communicate with a suitable outlet or vent pipe. As shown in Figure 2, the vent passage is interrupted at the front of the bowl, but it is obvious that the assage may be continuous if desired. In

addition, the bowl is provided with a water passage 15 which is located below the passage lland which is provided with outlet open-v ingsr16." Q The passage 15 communicates, with asuit ablesource of water supply. l The bowl is provided with a seat 17 and this seat is provided with a ventilating passage 18 having inlet openings 19. The passage 18 extends rearwardly' as at 20 and is provided with an outlet port 21w'vhichicorn municates with, a transversely arranged sleeve-22. v p LOcated within the sleeve '22 is avalve seat 23, and extending through this seat a sleeve va1ve 24. The valve 24"ezitends be yond the opposite sides of the bowl 10 and has secured thereto spaced arms 25 which extend from cover 26. f

The member 23 which Icoinprises the valve seatis stationary, while theslecve22 of the seat 17 rotates about this member,and the valve 24 of thecover 26 rotates within-this member. The valve seat 23 is provided with a port 27 and the valve 24 is provided'with a port 28. I The ports 27 and 28 locatedcentrally of while located within, the sleeve valve 24 upon opposite sidesof the center are 'dia metrically spaced ports also provided with diametrically spaced ports 30 which are adapted to communicate with the spacedports 29.

When the parts are arranged as shown in Figure 1 of the drawings, the outlet passage 14, which is open to the atmosphere, is in communication with the bowl through the openings 27, the passage 11 and the ports 29 and 30 which are arranged as shown in Figure6 of the drawings.

By raising the cover 26, the ports 21, 27 and 28 are brought into register, so that the bowl is in communication with the outlet passage 14 through openings 19. The valve seat 23 is provided with av finger piece 31, by means of which the position of its ports may be changed so as to provide communication with the outlet passage 14 when the cover 29. The valve 24 is the passage 18 and the 26 is closedipg and to cut ofl. communication when the cover is 0 en.

I desired a suitable tion may unit for forced draft or su c be provided with a single power a battery of bowls, and the valve may be adjusted so as to open the ventilating means only when the bowls are in use or vice-versa.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herea in reserved to make such erly fall within the scope claims.

Having described the claimed is i p 1. A ventilating device including a bowl having a ventilating passage and an outlet Vent, a valve sleeve having ports intercepting the ventilating passage and the outlet vent, a seat having a ventilating passage journaled to said sleeve and when in one position adapted to register the passage thereof with one of the ports of the sleeve, a valve journaled in said sleeve and having. ports, armssecured to the valve, a cover carried changes as propinvention what is by said arms and when in one position adapted to register the port of said valve with theports of the. sleeves and when moved into a second position adaptedyto move said last named ports out of registration. i

2. A ventilating device including a bowl having a ventilating passage and an outlet vent, a valve sleeve having ports intercepting the ventilating passage and the outlet vent, a seat having a ventilating passage journaled to said sleeve and when in one position adapted to register the passage thereof with one of the ports of the sleeve a valve journaled in said sleeve and having ports, arms secured to the valve,-a cover car ried by said arms and when linone position adapted to register the ports of said valve with the ports of the sleeve and when moved into the second position adapted to'move said last named ports out of registration, and a finger piece carried by the valve to permit the changing of the positions of the ports of said valve relative to the ports of the sleeve.

In testimony whereof I affix my signature.

WILLIAM l/V. MILLS.
