Application led September 26, 1908. i Serial No. 454,871.

' resident of St. Louis, Missouri, have invented certain new and useful Improvements in Automatic Intermittent Flushing-Valves', of which the following is a specification. containing a full, clear, and exact description, reference being had to the accompanying drawings, forming `a part hereof.

My invention relates generally to a valve, and more particularly to an automatic intermittent lushlng valve, particularly intended' for use in connection with water supply pipes of closet bowls, and the object of my invention is to rovide a sim le inexpensive valve which wil automatically and intermittently open to allow water to discharge through the sup ly pi e, and said valve being provided wit simp e means whereby the intermittent action can be accurately regulated, and the eriod of flushing accurately timed., i

To the above purpose my invention consists in certain novel features of construction and arrangement of parts, which will hereinafter be more fully set forth, pointed out in the claims, and illustrated in the accompanyingvdrawings in which 1 igure 1 is a front elevation of a valve of my improved construction, the same being shown inposition for use. Fig. 2 is an enlarged vertical section taken from the center of my im roved valve.

section ta enon the line3-3 of Fig. 2. Fig. 4 1s aside elevation partly in section of a modified form of my lmproved valve.

The housing of my improved valve is constructed in two main portions, 1 designating the rear portion, cularchamber 2, and` formed integral with the front of this portion 1 is a narrow vertically disposed housing 3, in which is formed chamber 4, and iixed to the front wallof the portion 1, and separating. the

chambers

2 and 4, is a diaphragm 5. Formed integral wlth the upper end of the housing 3 is' a tubular extension 6, which is adapted v to be connected to the water su ply pipe 7, and formed in the wall of the ousing 3, immediately "beneath this extension is a conical opening 8 whichd is normally closed b a conical valve 9. .Detachahly positione inv the upper end of the tubular extension 6, is a perforated plate or spider 10 provided with a depending pin 11 whichy enters a corre.-

't e purpose of guiding said valve Fig. 3 is a verticalV .ranged on `end of a corresponding link 28, the up of which latter is pivotally connecte and formed herein' is a c1rare formed integra wit s onding aperture formed in the valve 9, for during its vertlcal movement and arranged on said pin between the valve and the perforated plate 10 is an expansive coil spring.12. A passage way 13- establishes communication between the chamber 2 and the chamber within the tubular extension 6; and seated in the wall of thei housing 3 is a regulating screw 14 which is adapted to close this assage way. Formed through the wall inwhich the valve seat 8 is formed and establishing communica- 'tion between said valve seat or opening 8 andthe passage way 13 isa assage way 15 and screw seated in the wa in which this passage way is formed is a regulating screw 16 the forward end of which is adapted to close said passage way 15.

Fixed to the center of the diaphragm 5 is a horizontally dis osed pin 17 on which is formed a pair of ugs 18 and 19, and the forward end of said pin is seated in an aperture formed in the rear end of a screw 20, which latter is seated in the front wall of the housing 3. Located upon the inner end of this screw '20 and bearing against a disk 21 carried b the pin 17 is an expansive coilspring vertically/disposed lever 23 is fulcrumed upon a in 24 which latter is iixed in the side walls o the housing 3 and the upper end of said lever is rovided with a air of lugs 25 and 26.. A ink 27 is ivota 1y arthe pin 24 which lin passes between the lugs 25 and 26 and the upper end of this link is pivotally connected to the lower er end to the bottom of the valve 9.

29 designates a pivot bottonrof the housing 3 direct vertical alinement with the pin 24, and the center of the valve i9; arrangedto rock on the said pivot point is the lower end of a tube 30, 41n

point formed on the theupper portion of which is arranged to,

slide a 'pin 31, the upper end of which pivotallyv engages the lower end of the lever 23. Arranged on said tube 30 and in 31 and bearing against shoulders forme thereon is an expansive coils rin 32. Lugs 33 and 34 one of the side walls of the housing 3 beneath the pin 17, which lugs form stops to limit the swin of the lever 23; yfo'rme'd integral with one of 51e side walls ofv the housing 3 is a lug 35 which forms a stop to limit-the movement in one direction ric' l way 13 into the chamber 2, it-being underis forced upward through the passage way 13,

stood that the regulating screw 14 is set so as to 'permit water to dischargethrough said passage way 13. The pressure of the water within chambe'r 2 acts upon diaphragm 5 and slowly moves the. same toward' the chamber 4 which action 'shifts the pin 17 toward the screw 20, thus compressing the s ring 22, and at the same time causing the liig 18 to bear against one side of the lever 23, .and as l this movement continues said lever with its lower end bearing on the pin 31 is gradually moved into a vertical position, and as soon as.

the pivot point between the lower end of the said lever and pin 31 passes the center, the power stored' in the coil spring 32 willv instantly act to swing the lower ortion of the lever 23 over against the sto ug 34, and as this movement takes place t e lug 26 on the upper end of said lever .will bear against the correspondin side of the link 27 thus movlng the said k and link 28 into approximately vertical alinement, which action elevates and unseats the valve 9. The pivot point between thetoggle links 27 and 28 during this action moves slightly past the center or until the link 28 rests against the-stop lu 35 and thus the valve 9 is held in an unseate position, and the water from the supply pi e is n ow fr e to pass downward through t e conical opening 8 mto the chamber 4, whence it dischar es through the outlet pipe 36. A's

soon as va ve 9 is unseated the pressure in the chamber 2 1s relieved and the water therein owing to t e return of the diaphragm 5 to its normal posltion, which action is brought about by the expansion of the spring 22, and as this movement takes place the lu 19,\car ried by pm 17, will engage against t e correspondmg side of the lever 23, and said lever will be gradually moved into a vertical positlon, and as the pivot point between said le'- .ver and pin31 passes the center, the power stored in the spring 32 will act to throwsaid lever mto the position shown in Fig. 2; and as this movement takes place the lug 25 will bear againstthe corresponding side of link 27, thus shifting the link, and in turn moving thepivot point between the

links

27 and 28 past the center and as a result the power stored in spring 12 will act to reseat and close valve 9.

During the time the valve is elevated the In a modiiied form of the device seen in I Fig. 4 the

toggle links

27 and 28 are dis` pensed with and a trigger37 is ivotally carried by the upper end of the ever 23; and which trigger is adapted to engage pin 38 carried by the valve 9.
