IBENJ'AMIN 1l3. SHOLLENBERGER, OF MARSHIALLTOWN, IOWA,

Tooll whom it may concern:

Be. itqknown that I, BENJAMIN B. SHoL- L'ENBERGER, a citizen of the United States, and resident oi Marshalltown, in thecounty of Marshall and State of Iowa, have. invented a certain newand useful Sanitary Closet, of which the following is a specification. M y

My invention relates to sanitary closets of the type used where sewers and water are not readily availablefand which may be made in portable form.

The object of my invention is to provide such a sanitary closet of simple and inexpensive construction including a room havin therein a toilet, and a tank arranged be ow said room and said bowl and prefer ably subjected to contact with the outside air, with a vent pipe leading from the upper portion of said tank upwardly through the interior of said room to a point outside the room, and to provide a by-pass 01" special construction from the upper rear portion of the seat to the vent pipe. 1

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in which:

The figure shows a vertical, sectional view through a sanitary closet construction embodying my invention.

Insomuch the room forms an important part of my sanitary closet construction, I have shown in the accompanying drawings a room indicated generally by the reference numeral 10.

Suitably located within the room is a toilet bowl 12, on. the upper portion of which is a hinged seat 13, above which is a hinged cover 141. The lower portion of the bowl 12 discharges by way of a cylindrical vertical passage 15 to the upper part of the chemical tank 16, preferably arranged below and outside of the room 10.

The tank 16 has outside the room 10 an opening 17 above which is the tube 17 covered by a cap 18. The opening 17 serves as a clean out portion, and a means for the introduction of chemicals.

Communicating with the upper interior of the tank 16 is an airdischarge or vent pipe i p Speeification of Letters Patent.

Application filed July 5, 191a SANITARY CLOSET.

Patented May 9, 1922. Serial No. 243,358.

19 which extends upwardly through the 1 00011110 and has on its upper ends outside the room 10 a spaced cover cap 20.

Leading from the upper rear portion of the bowl 12 is a bypass pipe 21 which has atitsupper end a portion inclined upwardly to and communicating with the vent pipe 19.

The by-pass 21 is preferably smaller in diameter than the vent pipe 19.

My improved sanitary closet is designed to beused in localities where there is not an ample supply of water or where there is no water supply under pressure.

The tank 16 is designed to be partially filled with a suitable chemical 22, for reducing all solid matter deposited in the tank to liquid or semi-liquid condition, and for deodorizing the matter within the tank. It will be understood that the use of the chemical for the purposes herein mentioned causes a substantially continuous chemical reaction, resulting in the formation of gases and of some heat. There thus tends to be a continuous circulation of air through the upper portion of the tank 22, The parts are arranged so as to keep such circulation continuous, and to draw air from the room 10 into the tank and to pass it upwardly and outwardly through the pipe 19. Where the room is heated, such circulation is improved and increased, and such heating may occur, oi course, by artificial means as by furnace or the like, and of course it is supplied to some degree whenever a person is in the room.

I have found by long continued experiments that a device built as herein shown will result in air being drawn into the top of the bowl and thence downwardly into the upper portion of the tank 16, thence upwardly and outwardly through the pipe 19. A very small amount of air will sometimes pass through the lay-pass 21. The by-pass 21 conducts away a very small part of the air in the room and the odors in the tank, but I find that under some conditions the bypass is desirable.

By having the outer portion of the tank exposed to the outside air, and by having the pipe 19 running upwardly on the inside of the building, the pipe 19 secures the benefit of any heat within the room, and even when there is no artificial heat I find that the circulation desired is maintained, the heat from the formation of gases carrying the newly formed gases and odors upwardly out of the room.

In my various tests I have found it highly desirable to have the pipe 19 located withinthe room for the greater portion of its length, and tohave the tank 16 subjected to the temperature of the external air. If the pipe .19 is also subjected to the temperature of the outside air, the results obtained are not so satisfactory. v

The portion of the bypass pipe 21 which communicates with the pipe 19 isarranged at an angle of substantially forty-five degrees thereto.

Some changes may be made-in the details of the construction and arrangement of the various parts of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover by my present claim any modified forms of structure or use of meehanic'al equivalents which may be reasonably included within the scope of the patent to be issued upon this application.

I claim as my invention In a sanitary closet, the combination with a room, of a toilet bowl therein, having a seat and hinged cover, a tank below said bowl, a relatively large tubular conducting member between said bowl and said tank, a
