An annular Shoulder 35 is formed on said 10 valve stem 25 and'acts in conjunction; with an annular stop 36 forming part of thelimit the movement of plug or head 29 to relatively to the conthe valve stem 26 troller 19.

.At its lower end the valve stem-26 is. rece'ssed' or provided with a loop as indicated at 37 to receive the end of an operating or lifting arm 38. This arm is connectedwith or forms part of a hub 39 located in a lateral chamber 40 forming partof the discharge lchamber 14. in vwhich retaining guards 41 are also located in close 'roximity to said v hub. The hub 39 is provi ed with a central axially extending angular opening mto which extends-the angularl shaft 42 forming secured to the bearing portion 44 of th operating handle-45. The end of the" 'shaft 42oppositeto that at which the handie is located is pro'videdwith a screw- -threaded extension 43 arranged to ex g6 aqbearing sleeve 46 which together witfihe bearing portion 44 of the handle, is journalecl in suitable externally screw-threaded collars 47 forming part/6f the chamber 40;

water will be exerted-to lift the main valve,

'valve 0 eu'until the main valve is at the limit 0 its upward, stroke. The'discharge chamber is bythis-means brought into communication with the source' of water supply it being only ncces sary to keep the relief which fiushes the closet bowl. In the pre-n ;ferred form of construction, the'space above thevalve seat 20, whichunaybe termed-a dimensions to permit the main valve and controller, 1n operation, to be'ra-lsed entirely sure, so.

ressure of the said water on-t-he septum instantly closes the relief valve, main valve moves toward its seat.

the valve is filled with water under pres-' thatdf the handle is released, the

while the speed with which said main valve closes is i retarded by the water, which passes through valvechamber is at all times of s'ufiicient out of the discharge chamber and above the I said outlet when the valve the-by-pass2l.and isgoverned by the posi-' tion of the-time screwf22. Assoon as; the

By this means'any waterwhich'owing to the loose fit of the septum has assed beneath the same will thus be quick ywvithdrawn therefrom so that said septum. is readily and the septum is greatly increased by applying the pressure directly upon the same. Tl11S 1S accomplished by locating the septum within the controller, with pressure ports above it so that'when the main valve is closing and the controller enters the discharge chamber as before stated, the pressure entering the pressure chamber through the openings 19 acts directly on said septum to hold the re lief valve of less area firmly and securely u on its seat until the main valve is closed;

is improved construction does away with the necessity for weights or springs and permits of the use of a very short handle, a wheel or even a cross handle. In my structure I rely on the septum to close the valve under? ressure var in from three )ounds I static to over. one hundred pounds, thedevice operating with equal regularityand reliability under allconditions. Furthermore by means of the eje'oto'r' feature in this form of my invention the septum can be made to fit looselywithin the controller so as to allow a ireepa'ssage between the septum and controller for the water. the water is thus heavily charged with sediment, this sediment will be washed through saidspace and will not settle on the septum and clog the va ve.

Referring now more particularly to Fig. 2-, the construction of the valve piston, main valve, controller and connected parts is identicahwith that'shown in Fig- 1. The difference in this form of my device lies entirely' in the construction of the casing which, in this case ismade integral with the discharge chamber. 14* I instead of separate therefrom as in Fig. 1. in this last form of construction the valve seat 20, which come spondsto'the seat 20 thus also forms an integral part of the valve body or casing. The

= valve body 5' in this latterinstance is jormedivith acounter bored chamber 5* surround ng the main valve seat -20.

zutilityofthis counter bored chamber is the sameas my prior Patent Not fi s? ,183 *hereinbefore referred to. That is as the piston 'and'val-ve gradually move downward toward the valve seat the controller 19 will enter the discharge chamber lit and tl'n'ottle the flow of water which thus enters faster than it can leave and. collects in said counter boredchamber and forms a water cushion peneath'the valve 17 and valve disk 18. The

handle 4-5 and its connected parts which'may The pressure of this water cushion is exerted against the closing of the valve. and is maintained' to the instant of closing owing to the fact that it is impossible for the water. 1n

said counter bored chamber to leak out '7 through the small annular space between the walls of the discharge. chamber and the controller as fast as it enters through the annular space between the drain valve and the wall of the said counter bored chamber. The result is that the water cushion formed in this manner permits the valve to settle gradually and noiselessly to its seat and assists to prevent water hammering thereof. The life of the valve is thus greatly in- 30 creased and the necessity for continuousjrepairs is obviated.

If it is desired forany reason to discon nect the valve operating parts that is the be the same in all of my structures herein shown and described, the cap48 is first removed to expose thejsleeve 46, which may then be removed from the screw-threaded end 4.3 of the shaft 42; On loosening the cap 50 the bearing portion 44' with the handle, l5 and shaft 42 may be withdrawn from hub 39; and the collar 47. After this has been accomplished the hub.39 of the arm 88 will dropyi'nto and be held by the retaining 5 guards {t1 against dropping into the closet. Thec'ap 50 maysometinies be screwed up so-tightlyasto cause the packing to engage the bearing portion 44 with such pressure that the friction would ordinarily be sufiicient to maintain the handle, particularly a short light handle, in its upper position with the valve 'open or if not sufliciently' greafi to accomplish this would. delay the closing of said valve. In my improved structure this friction is easily overcome t-by the direct heavy pressure of the water on the septum in either of the forms of my device and the valve is readily and-quickly closed as in tended. 11o Itwill be seen that the loop 37 is, or rather the'walls forming said loop "are relatively. broad so as to enga' e the operating arm 38 throughout a considerable portion of the length. This construction overcomes any tendency of the stem 26- ito rotate due to the action 01 the rushing water while the valve is in operation. In other words, the flat walls of the loop 37 will engage and be held against rotation by contact with the arm 38. a My invention thus provides a simple and easily operated flush valve structure which is effective and noiseless in operation and does not readily get out order.-

Various changes inthe specific construc-, 125.,
