Patented Feb. 12, 1924. 194839392 UNRTED STATES PATENT OFFICE. ,TO3E[N C. SPEARING, OF CLEVELAITD, OHIO. AUTONATIC 3?RESSURE VALVE FOR FLUSHING TAN3KS. AppHeation filed May 15,1922. Serial No. 561,028. To allwhom it may concern.- Be it known that I, JOHN C. SPEARING, a subject of the Governme-nt of Oanada residing at Cleveland, in the county of Cuyahoga alid St,,tte of Ohio, have invented certain new and useftil Improven-ients. in Automatic P essure Valves for Flushing Tanks, of which the followiiia is a s-pecifi cation. . This invention relates to refilling mechanisms for flush tanks such as are used with toilets. It has for its principal object to provide a v,,ilve which is simple of construction and which is positive i-n action, the pressure of the water holding the - @alve in either the open or closed position. Anothet object is to provide a device of this character which has ,t shut off valve connected therewith so that in case it is desired to work upon the 20 tank or the vtlve the water ca-n be shut O:ff at the tank. Another object is to provide an improved float for op@rating said valve. Still another object is to provide means for adjustina the water level to wliieh the tank tt6 will filr to any desired height. A -still further object is to rovide means for refilling the bo-wl afte-r it has been flushed. In the drawinas Fig. 1 is a fragmentary. sectional view of -a flush -tank showing my ZO device in side elevation; I ig. 2 is a view similar to Fig. I t-,iken at right a'ncvles thereto showing the flush pipe ancl ball valve, also the overflow and refill pipes;; Fig.' 3 is a secti- nal iew tlii6ugh in- 'd evice,sh6wing 0 v y 35 the valve in closed position and also the water level at this adjustraent of the float; Fig. 4 is a view @ siinilar to, Fig),. 3 showing the valve in open @osition and the tank refilling. 40 In the drawings- I indicates a flush tank, 2 the 6utlet thereof '- which connects to'the bowl and 3 the flush ball valv'e. The oviarflow pipe is indi6ated at 4 a-nd the water supply pipe at 5. 46 Mounted on the upper end of the water supply pipe 5 is a valve casing 6 which has tho outlet pipe 7 tothetankeonnectedthereto and extencling dowi@f to near the bott6ni of the tank 1. The valve meelianism within the 59 valve 6@sing 6 to be hereinafter de cribed is operatea by the raisiiig or lowering of a pivoted - arih 8 said I @m 8 b6ing raised 6r Iti lowered by a rod 9 which has a float 10 adiustabl.y secured thereto. The rod 9 extends 12. The lower end of the rod 9 has a piston 13 thereon which works in a dash pot 14 -which is support . ed on one end of a rod 15, the other end of said rod 15 being connected 60 to the pipe 7. The float 10 is constructed of sheet metal - having its upper and'lower ends closed and having openings 16 cut through the sides toward s the upper end thereof. When the 65 tank is filled we@ter will flow through said openi ngs'16 into the flo-@t 10 and will remain therei n up to this level irrespective of the level of the water in the tank. When the taiik fills the water will rise around the 70 float 10 and will trap the air in the:float above the openings 16. M7hen the water reach es a certain height the float will rise it becom ing ligliter than water due to tlle air trappe d ,tbove , the opening 16. This is 75 clearly sh6wn in Fig. 3. It will bp seen by this construction I provide a weighted float which will always open the valve mechanism when the watet falls below a certain level. The valve mecha;nism -will now be de- 80 scribe d: The upper end of the supply pipe 5 is inserted in an opening), 20 in the valve casing 6. A reduded bore 21 communicates from the oponino, 20 to @ a, hemispherical valve s6at 22, and charribor 3@. The cham- 85 ber or bore 32 is closed by an externally thread ed plug 23 having an internally thread ed bore 24: Which plug is screwed into the opeii end of the bore 32. A screw 25 having a hemispherical head 26 on@ the, go lower end thereof is inserted in the threaded bore 24 and a lock cap 27 will lock the screw 25 and cop_sequently the'hee@d 26 in any desired position. It will be seen by this that the - water entering tl-ie valve can be reou@- 95 lated or it can be entirely cut off if desired. The o@p6site side of the valve casing is bored out as indicated at 28 to a certain depth and from there @,on has a reduced bore 29 making a shoulder 30 between the bores 100 28 and 29. A passage 31 connects @L'he bore 32 above the italve seat 22 witli the bores 28 and 29. A pistoii 33, 6pen at its upper end is adapted to -work up'and down in the bore 28 and has connected to thp, closed end 105 thereo f the' downwardly projecting pluo, 34 which is bored as indicated at 35 and has an upwardly presented, shoulder 36 midway tbereo f. A washer 37 is held in the recessed lower end 38 thereof@ by a screw 39 extend- 110 through a tube 11 within the float 10 and:is -ing upwardly from a rectangular guide rod @tdjustably connected thereto b a set screw 40 which works in the bore 41 of a coupling y
