TOILET rLUsHEa 't Y Application filed September 3, 1918; Serial No.` 256,335. l

To all whom t may concern.' f

Be it known that I, MICHAEL J. Snoirrz, acitizenlof the Unitedv States, residing at Cleveland', in the'county otCuyahoga and State of Ohio, have invented certain new and useful Improvements-,in Toilet F lushers, ofwhich thev followingisa speciiication.

This

andl the object of the same is to produce a hand-operated valve for flushing a toilet bowl.k 'v v The invention comprises details in the structure of the casing, the same being` made in two separable parts which whendisconnected-give acces'sto all the interior mecha.` nism :tor cleaning and repair. Specifically, the invention lies in the shape of the valve orplug and the seatk with which .it co-acts,` as well as the shape of the casing andA in the means for guiding the valve tol its seat accurately. Details are set'forth in the following specification andL claim, and attention is drawn to the drawings, wherein Figure 1 is a vertical'section through the Figure 2 is a plan View of the valve seat removed. t t .f v 1` Thelower member of this device comprises a cup-shaped body 1, having a lateral inlet nipple 2 externally threaded and formed with a nut at 3, the open upperA end of' the body'beingsurrounded by atlange 4t, and its lower closed vend carrying ade-- pending barrel 5 whose boreopens into the interior of the body at theupper end of the barrel andis closed at the lower end by al pet cock 6 so that sediment ywithin the barrel may be drawn ofi from` time to time.

Sediment is likely to pass into the barrelk 5 between the stem 31 and the inner wall of the barrel 5 and it no way is provided to remove this sediment, the opening koi the valve 30 will be retarded and in fact become very difficult.

The upper member includes a dome 11 whose larger' lower end conforms to the size ot' the upper end of the lower member and is flanged as at 14n, and whose smaller upper end is internally threaded as at 15, an arm 16 rising from the top of the dome and externally threaded and provided with a lined nut as at 13. The two membersv are assembled by placing the flange 14 upon the ange 1 and connect-y invention relates to baths and closets, and more especially to flush valves ;lv

ingv them `by screws or bolts kas kindicatedv at rer-ENT .YOFFl-CE-f 17,? and it'is obvious that-when these arey all mechanismy contained Upward into thethreadsl -is'- screwed' anl annulus 20`constit1`1ting a y*valve seat, its

lower-end being internally beveledfas'at 25 and its 'upper portion'p'rovided with'a pair otlugs'21'preterablyfopposite each other as shownv in 'Figure 2. Therefore,"when the lower member is removed from' they upper lmember and the @valve (described below)v withdrawn, a suitable tool can be passed upward into the 'valveseat' and engaged with the two lugs and turned so asltounscrew.

the seat from thevtlireads 15'r and withdraw it entirely. VThe valvefor plug 30 is in the shape of a double `cone and made entirely of rubber. It is mounted onv an upright stem 31 between anupper nut 32 and alower nut 33, and when these are tightened up. it is obvious that the rubber plug-valve will be somewhat expanded; Its upper coni-1 cal Vportionconta'cts with the beveled porticnf25 ott lthe valve seat whenrthe valve l is closed asshown in Figure 1. The lower end of the 'stem is by preference slightly reduced as indicated at 35, and plays freely in the bore Lofthe barrel 5 which therefore serves asa guidefor the same. Theupper portionof the stem is not threaded. llt

passes throughout tlicvlength of' the -arm 16 in the casing, and out vthrough the upper knob 'whichfis removable in an easy man-1 ner. It may be screwed onto the `stem or may beheld bya setscrew as shownv atl 87. j

A light/.expansive spring 38 iscoiled around end of rthe latter vwhere it is surrounded by".v

the lower portion'fof the stembetween the f lowernut 33 and the upper end of the barrel 5. I haveA described this valve as an entirety as standing kupright and such is the illustration in Figure 1, but I wish it to be understood that-it might stand hori- Zontal. g y

The action isas tollowsz Tater lowing in as indicated by the arrows enters the body 1 and assists the spring 38 in `holding the valve plug 3() upward against its seat, while the interior of the `arm 16 and nipple 12 are open to the outlet which in the present case would be the bowl of atoilet. When now the operator ioo desires to iush the bowl, he has `but to press on vthe knob 3,6. This moves the stem 31 downward and compresses the spring 38,

position until thespring 38 gradually forces the :valve upwardly to a closed position as' isgshown in i'ull lines. The-passage of the Water over the valve will also assist in causing the valve 30 -to move to a closed position at a slow :rate of travel. It will therefore be seen thatthe valve will remain in an open ory partly open position for some little time,

thereby eliminating the necessity of main-- `taining pressure upon the knob 36 in order guidedin the barrel and its `upper portion is guided :through the packing 18 and gland 19, and therefore the valve is always centered through the annulus and its upper conical portion .will always it accurately within the beveled lower endy 25 which constitutes the valve seat. Nevertheless, when it is desired to grind `or `clean this seat, the entire annulus can vbe removed in a manner above set` forth, Infact, whenever access to the interior. of this iiushfmechanism is desired for any purpose the two members can vbe readily separated by withdrawing the talreny out of place in a manner obvious to any plumber.`

The foregoing description and the drawings Vhave*reference,to what may be considered the preferred or approved form of my invention. lt is to be understood that may malte such changes in construction and arrangement and combination of parts, materials, dimensions, etc., asfinay prove expedient and fall within the scope of the appended claim..l y,

.Having thus described my invention, what I claim as new and desire to secure by Letters Patent is f ln combination, a casing constituting a valve .body and having an open top, a dash pot forming part of saidcasing at the bot,-

`toni thereof, a combined valve anddrain coclr at the lower end oi' said dash pot, an

inlet nipple communicating. laterally vwith the casing, a dome on the top of the casing removably secured thereto and closing said top, an outlet nipple extending laterally from thev dome, the lower portion of said dome being frusto conical in form, the dome immediately above the rusto conical form being cylindrically formed and internally threaded, a valve seat screwed into the internally threaded portion and havingr an opening therethrough truste-'conical at its lower end, a stem extending downward through said dome into said dash pot, the metal portion of said stein being threaded for a considerable yportion of its length, a

`valve mountedlon said threaded portion and ha ing a rusto conical upper end an inverted truste conical lower end, nuts on said stein above and below said if'alve'or adjusting thevalve longitudinally or" thestem, a coil spring surroui'iding the stem and having its lower end resting on top of the dash pot andy its upper end engaging the lower side or the nut below the valve, and a handle on the upper endo said stem.
