FLfiSEING-VALVIE.

i hiallwlwm it mag concerns Be it known that I,,THoMAs: RLPAvN a citizen of the United States of America, re-

siding at Pittsburgh, in the county of Allegheny, State of Pennsylvania, have invented a certain newand useful'Improvement in Flushing-Valves, of whichthe following is afullgclear, and. exact description, reference bein'g had to the accompanyingdrawings, which form part of this specification;

This invention relatesto flushing devicesor valves fonflushing closet bowls,- lavatories, and other sanitary apparatus.

' The-device, taking the embodiment shown" in the accompanying drawings, o f my invention, relates more commonly 'to that type oi valve'in which the main valve which controls the source of supply is operated by the differential-pressure of the water, this' pres sure being'controlled by a secondary or relief "valve, and its primary object is to pro vide asimple, durable, inexpensive and improved const-ruction therefor, whereby thereis provided a valve that is capable of causing a sustaineduninterrupted flow of an abundant supply offlushing water, without such I impetus of delivery as occasions splattering .or splashing within the bowl eratively manipulated 'by the depression and elevation of the closet-seat incident to use. As such a valve, its object is to provide mechanism which may. be easily manipulated without jarring and injurious ramming of the valve mechanism and whereby the valve 7 may be returned without liability of canting or sticking; and valve mechanism which is otherwise improved in detail ,of construction as will be hereinafter more fully de-- scribed.

T. will now deseril'io my invention so that others skilled in the art to which it appertains gnay understand and construct the same and, while reference is had to the accompanying drawings in'connection with 'this description, it. is to he understood that I do not desire to limit m-If; to the uni bodiniont of my iin ontionAlla'istraledin tlie drawingsit being prciriis d that the invention is \piihle of embo iment in various v Spiification of Letters Patent. 1 Application filed my 28, 1911, Serial n0. s41,o 1a.

Patented Dec. 31, 1912.

The particular typeof valve shown is of the class known as automatically operating valves, that is, valves which are operated by the depression and returning elevation of the closet seat, the depression of the seat s'erving to place the valve mechanism, as stated above, in condition preparatory to flushing upon-removal of the prejsure from and con setiuent elevation of the seat, and in Figure show a side elevation of a water-closet having attached thereto a flushing valve of the type mentioned, that is, of the-automatically operating type, and embodying my invention; Fig. 2 is an enlarged vertical sectiona-lview of the-valve showingthe valve 1n the closed or normal position it occupies when the seat is inclined'or elevated; Fig. 3

is a similar view showing the position of the valve mechanismimmediately upon dc pressionof the closet seat; Fig. 4 is a similar view showing the valvemechanism in fiushing position immediatelyafter release of the pressure upon the closet seat; and.Fig. 5 is a similar, but fragmentary view showing modified form of valve of this-same automatically operating typeand to be herein after more fully referred to, in the body of this specification.-

The valve illustrated is the-type in which the fi ushing is effected directly fromthesou'rce'of supply, that is ,.i' t is shown as having no auxiliary storage or flushing tank as is sometimes employed with valves of this class and as such the source ofsupply is indicated bythenumeral 2, leading into the inlet 3 of the casing 4. This inlet3 is formed by the chamber 5 laterally commu nicating at- 6 with the chamber 'i' of the casing 4.. Below the chamber 7 is the chamber 8 and leading therefrom, is the pa sageway 9, or discharge port-which cominunirates with the discharge. pipe 10 leading to the closet bowl 11, or flushing rim 12 of the closet bowl or other apparatus to be flushed. The wall 12" which separates the clnunher 8 and passage' 9 from the chamber 7 c and chamber fx has the .Opening 13 in which is disposed the screw threaded removable bushing This bushing 14 carries .at' its top the valve seat 15 formed coim'ilementary with the valve- 16 carried at the base of the piston l7. barrel-like member 18 having a suitable.

leathers andfdisks being clamped in position by the cap-piece23 having screw-threaded engagement with the top' clearly brought out. v 4

The" vfalve'16 has the-central bore 24 within which snugly fits the p'lug-lik'e stem 25 of the valve 26.. Thisplug 25 has the central inlet passage 27 leading to -the valve seat 28 which cooperates with the valve 26 to nor-' mally close communication of the said passage 27 with the chamber 29 of the barrel '18. This passage-way 27 is form'ed to register with the passage-way. 27 of the valve 30, which is adapted to beelevated as shown. in Fig. 3 into socketed engagement withthe bushing 14. This communication-of the pas-'- of the barrel 18 as sage-way 27 with that "of the passage 27 is effected by mounting of the'l'owerfend of the 'stem'25 within the'upwardly extending cuplike' head 31 of the valve- 30, and is maintained thereby'rat whatever relative operative position the-valve-may occupy. .This

The" pas'sa e 27" leads valve head 31, and the said bore 34-coinmunieates with the-annular-f ooket 36 which carried by the stem37o .the'valveand. into which leads the passage-way 27f, no matter in what'position thesmall lateral or,' annular opening 38 of the passage27 may 'l-ie .3vith respect to the entrance34. f

The stem 37 of the valve=30' rojects from. the casing 4 at the 'lower'end tereof This part of the casing is preferab'ly'separately formed, being indicated by-the numeral 39, and screw-threaded to the depending nippleportion 40 of thecasing proper. The upper.

pressure against the cap 23, the seat '28 is "carried upwardly into closing engagement with the valve 26 by an upward movement of the piston 17 The upward movement of the. piston results in the upward travel or further opening of the valve 16,- in which position it remains preparatory to the flushing operation which takes place immediatelyupon the ,removal. of the pressure on the closet seat andconsequent return of the' valve stem 37'and its valve 30 to normal po-V mal position, of course, as shown in Fig. 4, uncovers the .opening'within the bushing 14, bringing the chamber 7 and inlet chamber or passage 5 into direct and wide open com; mnnication with the lower chamber .8 and discharge passage-way 9. This communication enables the water to pass from the inlet 2 to the chambers and passage-ways just mentioned to the discharge port 10 and thence to the apparatus to be flushed while the valve 16 remains open. During this-flow of water, the chamber 7 above the piston 17 is being. filled from the source of supply through the openings 45, 46 and 47, where it exerts its pressure upon the piston 17 of large area against the slight resistance offered by the open lower portion of the chamber 7. The valve 16 preferably carries the head 16 which serves tochoke off the water and proportionately increase the pressure exerted at the top of the piston as the valve, through such pressure, gradually goes The opening 27 is preferably of a size that will prevent a too free discharge of water from the top of the chamber 7.

In Fig. 5 I show a modified form of valve employing my invention, wherein the cap 23 just-ing scre\v 53 in lieu of the o ening '47 shown in the preceding views, and depending from the cap or top of the casing 4%, is the wiper-rod 54-" which lies within the orifice 55 and serves, through the reciprocation of the piston 17 to keep the passageway 55 free from dirt or deposits. which. would otherwise tend to clog it. The coiled spring, carriedwithin the barrel 18 of the piston 17. instead of bearing against the under side of the cap 23, is interposed between the flange or shoulder of the valve 26 and the up or annular shoulthzr of the barrel 18, he upper portion of the valve stem tern'linati ng within the cap 23 and having the central here 57 intb which the lower end of; the \YlptW-lfltl 5i passes when the piston 17 is elevated. The opcrationof this valve is the same as that described above with 1h:- ex- Qcplion that. \vatcl passes from the chamber of thearrel 18 of the pistoiifl'i'to the-top l of the chamber? through thcopcniug .Li of the screw instead of the opening 4? i in the cap 23, as'showi in Fig. i. i

Further modifications in the structure shown'in the'accompanying tion. The valves, while of a design whichconduces to lightness and symmetry,may be constructed in various diiferent ways wh le drawingsmaybe made without departing fromrmy lnventhe general shape of the casing properand the disposition of the ports therein may also be varled without sacrificing my invention.

The device is simple in constructionand the specific embodiment shown is such that n the operation of the vallve,-the valve 30 as above described, is returned 'to its seat through the pressure of the spring 44, althou h' it will be apparent that pressure is exerte upon the upperface of the valve 30 by the water in the chamber 7 However, the return of the valve 30 is, independent of the return of the valve 16 to'its seat. This enables the valve 30 to immediately drop from the passage 13 and thereby uncover a large mouth or entrance way to the passage 9. preparatory to the slow, gradual closing of the valve 16 and resultant flow from the source of supply from the chamber 7 into the chamber 8 and thence tothe passage 9. i 1
