SPECIFICATION forming part of Letters Patent No. 349,347, dated September 21I 1886.

Application filed October 19, 1885. Serial No. IBOJEFS.4 (No model.)

To all whom it may concern:

Be it known that I, Pnrnron HARVEY, a citizen of theUnited States, residing at Ghicago, in the county of Cook and State'of Illinois, have invented certain new and useful Improvements in \Vater-G1osets,which are fully set forth in the following specification. 'Ihe invention relates to siphon waterfclosets, and has for its purposes, first, to provide a new means of exhausting the siphon by the flow of a current of water past the air-pipe leading from the siphon such that the flow of water for that purpose can be regulated according to the height and resulting pressure of the water, so that no more water shall be used for that purpose than is necessary; second, to prevent the air which ,is drawn from the siphon being discharged into the bowl and thence into the room, and to cause itinstead to be discharged into the soil-pipe or sewer-pi pe, whence it will pass through the usual ventilating-pipe to a Ventilating-flue orto the outer air; third, to prevent any air which may at any ltime be driven from the siphon by the iiow of water into itfroin the bowl being admitted into the bowl or by any course into the room, and to cause it instead to be forced into the soilpipe and thence to escapeinto the Ventilating shaft. I

In the drawings, Figure l is a vertical section of my improved water-closet and the tank and connections therewith. Fig. 2 is a horizontal section through w a: on Fig. I. Fig. 3 is a detail vertical section showing the adjustable mouth-piece of the air-pipe leading from the Siphon.

A is the bowl.

A is the evacuatingsiphon.

A2 is the lower trap.

A3 is the soil-pipe. L

A4 is the iinshingrinn;

B is the tank.

B is the service-box.

C is the service-pipe which supplies the tank.

C is the ordinary ball-cock which controls the supply of water to the tank.

b is the valve which controls the flow of water from the tank to the service-box. 4

b is the valve which controls the flow of water from the service-box to the closet. Both said valves are connected to the lever B2, pivoted above the tank-one on one side the iulerum and the other on the other side, so that one is opened when the other is closed. The chain bi, attached to the end of the lever B2, is designed to be connected in any convenient and familiar manner with the closet seat, so as to be pulled down when the seat is depressed.

Thus far the construction is of a Well-known form, and I will not describe it further in detail. The service-box B has the portion B, which may be a pipe communicating with the tank at the high-water niark and open at the top, affording a convenient channel through which to extend thel connecting-rod b, by which the lever b2 actuates the valve b', and also constituting an air-ventfor the serviceboX. rIhe flushing-pipe E is inserted through the bottom of the service-box, and stands up within the latter a short distance, E. At the interior bottom of the Servicebox the pipe E has the apertures e e e, which will allow a limited iiow of water from the Servicebox into-the service-pipe. At the-top of the lsiphon A', I secure the box D, having at oneend the nipple D, which' makes a water-tight junction with the iiushing-rim A at the aperture a", and having at the bottom thenipple D2, which makes an airtight junction with the Siphon at the aperture a. At the back side boX D has the nipple D, to which the flushing-pipeE is conneeted. On the lower side near theend farthest from the bowl the box D has the nipple Dt, to which is connected the pipe F, which leads thence down behind the siphonand lower trap and discharges into the soil-pipe A3 at f beyond the lower trap, A2.

Communication from the siphon A to the pipe F is made through theduct d, made up as follows: A short vertical pipe or duct, D2", extends from said nipple up through the box D and opens .on the upper sid e, the aperture D200 being closed by the plug or cap (i200. Communicating with this duct D20 at the side within the box D is the horizontal duct or pipe D21, which.

leads to the short vertical duct orl pipe D22, which is located at the end of theboXD farthest from the bowl and opens at the top, the aperture D220 being closed by the plug or cap (122. Said pipe D22 terminates open a short distance above the month d* of the pipe F, with which itisconcentric. Itisinteriorlyscrew-threaded and has screwed within it the collar d22, which may be made to protrude below its lower end and constitutes therefore an adjustable extension of said pipe D. From the bottom ortioor of the box D anywhere between the apertures a' 5 and d* are erected two partitions, IY and D, extending nearly to the top of said box and making water-tight junctions with both bottom and sides, and from the top of said box between the said partitions is suspended a Io similar partition, Di, reaching nearly to the bottom. These three partial partitions make a trap which prevents thcpassagc of gas from the sewer or soil pipe back to the bowl or to the tank.

rlhe operation of this entire device is as follows: then the chain b2 is pulled down bythe depression ot the seat of the closet, or in any other manner, the valve b is opened and the valve b is closed and the service-box fills. 2o NVhen the chain Z is released, the valves are reversed, b being closed and b opened, and the water from the service-box flows freely through the flushing-pipe E into the box D, and thence into the bowl, flushing the same, and also out through the pipe F, which is entered through the annular aperture between the end of the collar dit and the aperture d. The portion of water which takes this latter course induces a suction of air from the `siphon 3c A, drawingit through the duct d made up of the pipes l)`-",l')l D', thus exhausting or rarefy` ing the air in the siphon and causingitto evacuate the bowl. The water passing through F carries with it the air or gases drawn from the Siphon and discharges into the soil-pipe. The air or gas mixed with the water while it is passing through the pipe F has an opportunity when it reaches the larger soilpipc to separate, and then escapes through the 4o Ventilating-pipe connected tothe nipple a?. \Vhen the water in the service-box falls below the top of the pipe E, it ceases to flood the bowl, the escape being limited to the apertures e c at the bottom ofthe service-box, and the quantity thus furnished being less than the capacity of the aperture a, leading` to the bowl. None is furnished to the pipe F, and not enough to the bowl to keep the siphon full. lhe water in the bowl falls to the line u n, and air being then admitted to the siphou,

it ceases to act as such, and, as the water continues to iiow from the service-box through the apertures c e and into the bowl, it constitutes an after-wash, filling up the bowl and shorter limb of the siphon to the line g/ y, and the remainder flows off freely to the sewer, leaving both traps of the closet filled. XVhile the short limb oi' the Siphon is filling up, and at any other time when water is ilowing nor 6o mally through the siphon and so displacing air therefrom, the air has a free avenue of escape through the duct d, pipe F, and ventilating-pipe connected to the nipple as. If the closet is to be operated bya hand-pull, instead of by the scat, the valve b may be omitted, the excess of the size of the aperture from the tank to the service over the size of the flushing-pipeEeausing theservicebox to fill while the water is flowing from it to flush the bowl. It will be observed also that in either case the duct B serves as an overflow from the tank to the service-box, and thence through the apertures c c to thefiushing-pipeand the bowl, so that in ease of any derangemcnt in the ballcock C preventing it from closing, the water will allpass through the closet into the sewer. For this purpose the total area of the apertures c e should be sufficient to allow the escape of as much water as the cock C can admit to the tank. It will be observed also that the pipe E should have a cross-section equal to that ofthe pipe F added to the area of the aperture u, in order that it may furnish enough water to both flush the bowl, (furnishing for that purpose as much water as the aperture a" will adxnit,) and also supply the pipe F, for the purpose of exhausting the air from the Siphon. The amount of water required for the latter purpose will depend to some extent upon the speed of the currentinto the pipe F around the mouth of the duct d, and that speed will depend upon the height of the service-box above the closet or any other circumstance affecting the presslllC. be adjusted to the circumstances and the mini* mum quantity only of water used, 'll provide the collar d, adustable up and down from and toward the aperture d, to increase or diminish the area of access to the pipe F from the box D. To reach this collar and adjust il, the plug Imis removed by a wrench and a screwdriver used to engage the collar r'" and screw it up or down.

In order that free access maybe had tothe pipe F to clearout any obstructions which may lodge therein, the pipe DL, forming the last section of the duct (l, is made the full size of the pipe F. Il' necessary to give fuller access to the pipe F,thc eollardtimay be screwed out at the top of the pipe lhe trap formed by the partitions Df, D, and l)T in the box l) serves to prevent sewer-gas passing by way of the pipe F from the soil-pipeinto the service box, and thence into the room.

lt is obvious that the box D may be removed from thc closet and connected thereto by two pipesone from the nipple D' to the aperture a into the flushing-rim A, and another from the nipple D2 to the aperture a into the siphou, but by locating it, as illustrated, immediately above the siphon and against the bowl,the use of such pipes is made unnecessary. rlhe box D is convenienty secured in place and tight connection effected b v forming flanges H H on the top of the siphou, and flanges 011 the bottom of the box D, using rubber gasketsjj, slipped over the nipples D and D, countersinking the apertures a" and e to fit the nipples, respectively, and binding the box D to the closet by bolt-s through the flanges on both ,having first forced thebox laterallyto crowd thenipplc D tightly into the counter-sunk aperture a.

In order, therefore, that the device may I It is obvious that functionally the chamber of the boxD is a part of the water-duct from the service-box to the soil-pipe, and also a part of the water-duct from the service-box to the bowl, and that said ducts merely meet and unite in said box,being one duct from said box to the service-box, and I do not limit myself to the particular structure of said two ducts which is here illustrated as involving said box; but any structure involving the two ductsone leading to the bowl and the other to the soil-pipe beyond the closet-traps,the latter being connected with the air-duct from the siphon, so as to exhaust it-Awould involve the essence of my invention.

I claim- 1. In combination,substantially asset forth, the bowl, its siphonic evacuating-pipe and traps, and discharge-pipe to the sewer, the water-ducts, one leading to the bowl and the other to the discharge-pipe beyond the traps, and the air-duct leadingfrom the siphon into the latter water-duct, so as to be exhausted by the water-current through the same.

2. I n combination,substantially as set forth, the bowl, its siphonic Vevacuating and discharge pipe, a watenpipe, an air-pipe from the siphon opening within the water-pipe, and an adjustable mouth-piece Afor said air-pipe, whereby the water-aperture around said airpipe may be regulated at will.

3. In combination,substantially as set forth, the bowl, its siphonic evacuating and discharge pipe, the box D, communicating with the bowl and with the siphon, the water-pipe E, leading into said box, the water-pipe F, leading out of said box, the air-duct d, leading from the siphon and terminating near to and concentric with the opening into said pipe F.

4. In combination, substantially as set forth, the bowl, its siphonic evacuating and discharge pipe, the box D, communicating with the bowl and with the siphon, the water-pipe E, leading into said box, the water-pipe F, leading out of said box, the air-duct d, leading from the siphon and opening within the box D, having its terminal branch in line with the pipe F and its mouth near to the opening into said pipe, and provided with the aperture D?lo at the surface of the box D, and the interior collar, d, constituting an adjustable mouthpiece accessible through the opening D22.

5. In combination,substantially as set forth, the bowl and its traps and discharge-pipe, the water-pipe, and two water -ways supplied thereby, one ieading to the bowl and the other leading to the discharge-pipe beyond the traps of the bowl, and having a trap to prevent return of gas from the sewer into the bowl or service-box.

6. In combination, substantially asset forth, the bowl, its siphonic evacuating-pipe, traps and discharge pipe, the water-pipe and two water-ways supplied thereby, one leading to the b owl and the other leading to the discharge-pipe` beyond the traps of the bowl, and provided with a trap to prevent the return of gas from the sewer, and an air-pipe leading from the siphon and opening into the second water-way beyond the trap therein.

7. In combination with the ,bowl and siphon iliade integral and having the apertures a* and a', respectively, and the flanges H H, the box D, having the nipples D and D2, to fit said apertures, respectively,and the fianges H H', whereby it is secured to the bowl and siphon, substantially as set forth.

In testimony whereof I have hereunto set my hand, in the presence of two witnesses, at Chicago, Illinois, this 14th day of October, A. D. 1885.
