AUTOMATIC VENTILATING DEVICE FOR WATER-CLOSETS.
To all whom it may concern Be it known that I, ALrHEUs J. GRrrToN,
a citizen'of the United States, and a resident of Worthington, in the county of Nobles and State of "Minnesota, have invented a new and useful Improvement in Automatic Ventilating Devices for Water- Closets, of which the following is a full, clear, and exact description.
My invention relates to improvements in automatic ventilating devices for water closets, and it consists in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide a device, by means of which the bowls of water closets may be ventilated, rendering the closet of a more sanitary nature.
A further object of my invention is to provide a system of the type described, by means of which a fan is automatically set into operation while the closet is being used.
A further object of my invention is to provide means for preventing a back flow of the gases or foul air into the bowl while this device is not in use.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a diagrammatic view showing one embodiment of my improved ventilat- I ing system,
Fig. 5,
Fig. 2 is a sectional view through a portion of a closet seat,
Fig. 3 is a sectiOn along the line 3-3 of Fig. 4 is adetail view, partly in section, of a portion of the device, and i Fig. 5 is a plan view of the seat.
In the drawings, 1 and 2 indicate bowls of water closets and 3 a tank for flushing the bowl. The construction of the bowl itself is ordinary, and may be of any suitable construction. Each bowl is provided with a seat,
such .as that shown at 4. As will be seen from Fig. 2, the seat is hinged at 5 to lugs or ears 6 carried by the bowl in the usual manner- Each seat is provided with a recess 7 in which are disposed spring contacts Sand 9 respectively, these contacts being connected by conductors 8 and 9 Specificationof Letters Patent.

Application filed April 26, 1920. Serial No. 376,701.
and 11 respectively. An insulating push button 12 is provided, which projects through the bottom of the seat and which is mounted to move in a ring-shaped guide 13.
The seat portion 4 has a tubular housing 14 which receives a tubular portion 15 secured to the bowl 1. Disposed within the members 14 and 15, which are telescopic as shown, 1s a spring 16 which normally keeps the seat in a raised position. In the drawing I have purposely exaggerated the distance which the seat is raised when not occupied in order that the operation of the device may be readily understood.
The seat, as stated, is held normally from the bowl by the spring 16, but when it is occupied the spring is compressed, and the push button 12"engages the bowl, thereby closing the contacts 8 and 9.
At 17 I have shown a pipe which is connected by means of branch pipes 18 with each of the bowls. The latter are provided with discharge openings, such as that shown at 19 in Fig. 3 and located at a point between the hinges 5. The pipe 17 communicates with a valve casing 20 in which is disposed a valve 21 adapted to rest normally on a valve seat 22 (see Fig. 4). A valve stem 23 extends upwardly through a guide portion 24 and bears at its top an armature 25 for the magnet 26.. The latter is on a secondary circuit of a transformer 29, being connected o the wires 10 and 11 bymeans former 29 is connected by conductors 30- and 31 with feed wires 42 and'41 respectively.
The lower part of the valve casing 20 has a ,pipe 34 which leads to a fan 35 driven by a motor 36. The motor is connected by a conductor 37 with a spring contact 38. A- companion spring contact 39 is connected 40 with the feed wire 41. The other feed wire 42 is connected by a conductor 43 to the opposite terminal of the motor.
Fromthe foregoing description of the various parts of the device, the operation thereof'may be readily understood. Normally the contacts 8 and 9 (see Fig. 4) are open, but when the seat is occupied, these contacts are closed and a circuit is established through the magnet 26 in the secondary circuit of the transformer 29 and by conductors 27, 10, 8, contacts 8 and 9, feed wire 11, and conductor 28 through the magnet. This energizes the magnet 26, whichpulls up on the armature and opens the check valve 21. The upward movement of the stem 23 causes a collar 14 to engage the contact 39 to bring it into engagement with the contact 38, thereby closing the circuit from the'feed wires 41 and 42 through the motor. The.- actuation of the motor drives the fan 35 which draws the foul odors and gases into the pipe 17 through the casing 20, and pipe 34, and forces them out of a discharge pipe 45. When the pressure on the seat 4 is released, the spring- 16 forces the seat upwardly, breaking the circuitat the contacts 8 and 9 and deenergizing the magnet, whereupon the valve 21 drops downwardly and the contacts 38 and 39 are broken, thus cutting 01? the circuit of the motor and restorin' the apparatus to its normal condition. t is obvious that the use of any seat in the system will cause a circuit through the magnets 26, as long as the transformer 29 is connected with the feed wires 41 and 4:2.
This system is especially desirable in large buildings, such as schoolhous'es, dormitories, apartment buildings, etc. The provision of the check valve 21 prevents any back flow of thefoul air into the bowls. The. device being' automatic in its nature, requires very little attention,
