Be it known that I HOMER MonRis, a citizen of the United States, residing at Hermosa Beach, in the county of Los Angeles, State of California,-have invented new and useful Improven'ients in Flushing Apparat-us, of which the following is a specification.

My invention relates primarily to apparatus for flushingwater closets and is illustrated and described herein as applied to that purpose, although the apparatus may be used for other purposes, and the object thereof is to provide a device of Simple construction and compact form in which the controlling valve is manually started to coinmence the operation and is held open automaticall-y until the flushing is completed when the controlling valve will return to-its I accomplish this object by the apparatus described herein and illustrated in the accompanying drawii'igs in which z- Figure l is a sectional front elevation ofthe flushing apparatus. Fig. 2 is a side elevation of the controlling valve partly in secgtionland showing it connected to the closet )ow In the drawings 5 is the supply pipe which is connected to a source of water supply under pressure of a suiiicient head for flushing purposes. sually this will be the city water This pipe is provided with a regulating cock 6 and is connected to and opens into an air chamber 7. I have shown a sup ply pipe connected to the air chamber at the bottom, but the connection may be made at the top, or at any intermediate point between the top. and bottom, providing the supply pipe passes a point on a level with or below the bottom of the air chamber. Leading from the bottom of the air chamber is a pipe 8 which is connected to the casing 9 of valve chamber 10. The top of valve chamber casing is preferably closed by a plug 11 which is provided with a down-.

wardly projecting flan e 12 which is exteriorly threaded. On tns flange is screwed a tubular regulator 13 which can be screwed up or down upon-the flange to regulatethe distance between the regulator and valve seat 14 which is formed on the casing 9 at the bottom of the valve chamber, whereby the volume of water flowing through the valve chamber can be regulated. Below the valve seat, casing 9 is reduced in size and is pro- Specificat'wn of Letters Patent. Pg icentefi Aug, Application filed March 22, 1907 Serial No. 363,978.

vided with a boss 15 through which projects the valve ope-rating shaft 16, the innercnd of which forms a crank or eccentric 17. On the outer end of shaft 16 is the operating handle or lever 18. \Vith-in the boss and connected thereto and surrounding shaft 16 is a stufiing box 19 to make the joint around the shaft water-tight. On valve seat 14 is valve 20 which is secured upon the top of valve stem 21 in any suitable manner. This valve when raised off its seat passes up into regulator 13,. This regulator forms a cupshaped receptacle in which the valve, when raised, is held by the flow of the water until the pressure inthe air chamber is relieved.

The lower end of the valve stem is bifurcated and the furcations 22 thereof straddle crank 17. To the lower end of the casing f, is secured flushing pipe 23 which leads to and is connected with the closet .bowl 2A. I prefer to place the air chamber-and the valve casing within the partition wall and to cover the opening necessary for the insertion at these parts by a removable plate 25 which can be taken oil when it is desired to remove the parts for repair. A slip coupling 26 as, rac

permits of the disconnection of the valve casing from the flush pipe, and a union '27 on pipe 8 permits the removal of the valve casing without interfering with the an chamber. By unscrewing plug llthe valve can be removed from the casing and replaced after being repaired. When installing this apparatus the air chamber would preferably be connected up when the plumbing of the building was roughed in, althouglri it could be installed afterward.

here there are closets on the same floor on the opposite sides of the partition the pipe 8 may be provided with a branch which would lead to another valve casing containing a valve and other connections similar to those described herein. It will be understood that the air chamber is of suitcient capacity to hold the desired quantity of water for flushing purposes, but that it does not require a capacity suilicient to hold all of the water required for a single flushing of, the closet, as a certain amount of supply will be' furnished through pipe 5 during the flushing operation.

With my flushing apparatus in. position and properly connected, when it is desired to flush the closet, the operating handle would be turned to throw the valve into the regulator, when the water would flow downwardly around the bottom of the regulater passing on through the using and "flush pipe into the bowl in the usual manner.

The fiow of the water under t lieved, when the suction of the water pass ing through the lower part of the valve casing and the weight ofth-c valve will cause the valve to automatically seat itself. The supply of water passing through cock t3 must be less than the amount of water which can be'discharged through the valve cham-. her, and the time that itwill take for the valve to reseatitselthwill be regulated, first by the quantity ofwater which accumulates in the air chamber, and secondly by the amount of water that 'is'permitted to flow into the air chamber during the process of 2C flushing. It will be observed that it the quantity of water entering the air chamber through pipe 5 was equal to the quantity of water discharged through the valve chamber when the. valve wasa'aised into the regulator it would remain in that position as long as the waterilowed, and it isnecessary there fore that the supply of water entering the air chamber shall be less than that discharged through thevalve chamber. It will also be observed that ,thevolume and velocityjot' flow of'water passing through the valve chamber, is controlled by the regulator 1 sothat my apparatus canjbe used upon any water systemwhether the pressure be high or lowg If the pressure is higln the distance between the bottom ofthe regulator and valvel seat would] be inuch'less than if the pressure were low, the distance being regulatedfin accordance with'the @prcsstu'e. It 40 will'also be observed that after the valve is ,seated the \vaterpressure of the main causes the wate rto accumulate in the air chamber until theairis compressed to a point equal to theljvater pressure, and that when the 15 valve unseated this air pressure is exerted onthe whole body of the water in the air chamber-and that during the fiushingprocess a fee n quantity.ofwater-fiows through the valve is reseate'd, iltwill also be ob-, served, that as, longa-the air pressure in the the supply;'pipegand a ds in. flushing until hamber ended by, the inflow; of water; from the service pipezvisi sufiicfient'to dis-1 2h egv a ter through itheflval ve chamber velqcitya utl'icieutj-to-zhold the, valve he: v regulatorqthea fiushin I ne regulator ,5 will hold the valve up in. the regulator until the air pressure in the air chamber is iei weight at the valve and the stem and the g proceeds;

but that as soon as the velocity of the water is not sufficient. to hold the valve in the regulator it will automatically return to its seat. it will also be observed that in causing the valve to reseat itself there willbe the suction of the water below. \Vithout the use of the regulator the valve would remain uuscated the same time whether t e pressure was high or low and would therefore be an misatislactory tl]')[):l1'tltllS as I have found from my practice] experiments;
