'VENTILATING GLOBET.

Application led December 15, 1923. Serial- No. 880,978.

To all whom it may concern Be it known that I, CHARLES E. J AcKeoN, a citizen of the United States, residing at Minneapolis, in the county of Ottawa and State of Kansas, have invented new and useful Improvements in Ventilating Closets, of which the following is aspecification.

It is the purpose of this invention to provide a ventilator designed for use in combination with stools of ordinary construction in bath room fixtures, and wherein use is made of a suction pipe 'for conveying the fumes to a4 stack or discharge pipe with which the suction pipe communicates.

In carrying -out the invention I employ a small electric motor for creating a suction in said suction pipe, the motor being 1ncluded in a normally open circuit which is automatically closed when the seat of the stool is lowered, thereby operating` the motor and continuing the latter in operation as long as the seat is occupied.

Another object of the invention resides in the provision of a normally closed valve for controlling communication between the stool and said suction pipe, the valve being automatically opened by lowering the seat of the stool and maintained while the seat is occupied.

The nature andadvantagcs of the inven-4 tion will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as Y claimed.

In the drawings forming part of this application, like numerals of reference indicate similar Aparts in the several views, and wherein:

Figure 1 is a view showing the Ventilating device associated with a stool of the character above mentioned, the seat of the latter being in a closed position.

Figure 2 is a fragmentary view of a stool showing the seat in its normally elevated position and the position of the valve with relation to the suction pipe.

Figure 3 is a view of the modified construction.

Referring to the dicates a stool of theordinary well known construction in bath room iixtures, while 11 represents the seat for said stool. In connection with the seat 11, I make use of an in an open position drawings in detail, 10 in-` with re auxiliary seat 12 which is arranged beneath the seat 11 and attached thereto for opening and closing movement therewith. The upper side of this auxiliary seat'is provided with an annular channel or passage through which the fumes pass through the exit opening 14 formed at the rear ofthe auxiliary seat, and which opening, when the seat is, closed coin` cides with the receiving end of a suctibn pipe 15. This annular passage or channel come' muni'cates with the stool 10 by'l a plurality of openings 16 arranged at spaced points about vthe inner edge of the auxiliary seat as shown.

The suction pipe 15 conveys the fumes received from the channel or passage into a discharge ipe or stack represented at 17, from whici the fumes pass to the atmosphere.

For the purpose of creating a suction in the pipe 15 I employ a small electric fan 18, the atter being included in a normally open circuit, which also includes a switch adapted to be actuated by the closing of the seats 11 and 12. An electric core or wire19 extends from the switch just referred to to the electric fan. This switch includes a stationary` plate 20 which is provided with spaced contact points 21, the plate 2O being secured to the seat support 22 immediately at the rear of the seat. The switch further includes a movable plate 23 which carries an elongated contact element 24, the plate 23 being secured to the rear edge of the seat 11, and normally spaced 'troni the contact points 21 of the plate 20, as the seat is normali supported in a raised or elevated position. iowever, when the seat is lowered or use, the contact 242 is brought into engagement with the Contact points 21 thereby closing the circuit to the fan 18, putting the latter into operation, and continuing the latter iii operation as long as the seat is occupied.

For the purpose of controlling communication between the stool 10 and the suction pipe 15 I employ a normally closed valve 25 having a stem 26 arranged in the path of movement of the seat 11. This valve revents the returnof fumes into the stoo 10 and into the room from either the suction pipe 15 or of the osition of the stem 26 of this valve ation to the seat 11 it is obvious that when the seat is lowered for use, the valve is moved to an opened position, which position is maintained as long as the seat is in `its sis the discharge pipe 17. By reason :the Seatis elevated. v

In Figure 3, I have shown a modified form `of the inventiomwhereinthe stool 10 is cast with a bore or opening 15 which takesthe place of the suction pipe 15 shownin 'Figure 1, thereby eliminating the arrangement or use of the pipe exteriorly of the stool. However the invention shown in Figure 3 is used in the same manner as described in connecr-tion with the Apreferred embodiment of the p invention.

desire to have it While it is believed that `from the. foregoing description, the nature and advantages of the invention will be readily ap arent, I

understood that l do not .limit myself to what is herein shown and described, and that such changes may be re- Ammm sorted to when desired scfpeof what is claimed.

aving' thus described the invention,I claim: c

The combination with a toilet bowl provided with a compartment in one side which has colnmunication bowl, a Ventilating pipe leading from one end of the compartment, a spider arran d as mi rwithin the with the interior of theV in the compartment provided with a va ve seat, a valve adapt-ed to normally engage the seat, a knob on and adapted to upon lowering the valve to open position,

be engaged by the bowl seat and a spring engaging the 'spider and knob for normally 35i holding the valve seated.`

In testimony whereof I afix my si ature.
