My inventioncon'sists in the novel yfeatures hereinafter described, referencegbeing had to the accompanying drawing which' illustrates one embodiment of the invention selectedby me for purposes of illustration, and the said invention is fullydiselosed in the followingdescription and claims.
The object` of my inventionis to provide V an inlet valve mechanism for flushing tanks adapted to be controlled by a floatand float lever, in which the maximum .eiiicieney combined with eXtremesimplicity and cheapness of manufactureis obtained, the porvtions, of the ,device subject to wear andreplacement being readily accessible. to. the ordinary householder, sothat all necessary repairsandreplacements maybe madeby an unskilled person without the delayA and eX- pense incident to the. employinentof skilled y labor, the said valve mechanism being so.
constructed that it may be read-ilyinstalled 'in any of t-he ordinaryfiush tanks now in use. where desired,
for the purposev offrei pairing or refitting the same.
Referringv to the drawing,

Y i Y Fig. 6 represents a-sectional view of Ethe lower portion of the valve body showing ythe manner of connecting an after-fill -pipe therewith, when desired.
Fig. 7 is a bottom plan view of a muflling collar with which the discharge pipe from the valve mechanism is provided, as shown in Fig. 2. Y i
ln the accompanying drawing, 1 represents a flush tank which may be ofany usual or preferred construction.'A These :provided withf` a Lremovable cover, v,as indicated at'2, butniy invention is applicable to'f'tanks generally, regardless Vof the material of whichY they ai'e made. rThe tank is 'shown provided with a, discharge or.
ilushing pipe, 3, controlled by any "usual or preferred type of. flushing valve mechamsm, 'which isnot ,herein shown or described, as' it formsno part of my present invention. I have, however, shown the tank provided `withthe usual overflow pipe indicated l at 4.' In the form ofmy invention herein shown, y represents'v a verticallydisposed'r inlet pipe within the tank which `screws into a fitting, 51, having a threaded sleeve portion, lafextendmg.through an aperturein the bottom of the tank, and secured toV thetank ,bottom by a nut, 511. The threaded sleeve, 51?, ,is lconnected with a `water supplypipe, 52, in any usual or de-' sired way. The upperend of the inlet pipe,
that this" part can be readily produced in quantity on van ordinary screwy machine. Vithin the sleeve, 53, is a separate valve seat member comprising a polygonalv body, l y preferably square, indicated at.58,ofA suoli diameter through 'the opposite corners thereof, thatitmay be forced byfpressure into the bore of the sleeve, `53, so that the sharpcorners of the block willV seat themselves in thev metalof the sleeve, and` retain the valve seat member permanently in the sleeve until' it is desired to drive it out. The block, 58, is internally threaded kto receive the upper end of the Water inlet pipe, 50, which is screwed therein, and the upper part ofthe block is turned downto provide an annular valve seat, 59, the' outer edges of` whichare preferably slightly beveled ory rounded, asindicated at 59a. This part may alsoV be economically produced in v quantity from. square or polygonal stock on a screw tanks are usually made of porcelainwand machine Itk will be noted that y when the block, 58, is forced into position within the sleeve, 53, as indicated for example 1n Fig. 2 and Fig. G, an annular space is provided withinthe sleeve, as indicated at 57, surrounding the valve seat, which communicates by means of the segmental shaped vertical passages, 57, with the lower portion of the sleeve into which thevertical discharge pipe, 56, surrounding the water inlet pipe, 50, is screwed. 4The discharge pipe, 5G, does not extend to the bottom ot the tank, and the annular passage is thus yformed, indicated at 60, between the inlet pipe, 50, and the outlet vthe klitting, 51, and leave an annular space,
82, 'for the discharge of the water into the tank.y This annular space, 82, will be oi much greater capacity than the annular space, 60, between the inlet and discharge pipes. In order to hold the lower edge of the muiiler sleeve sutliciently above the tank bottom to insure the free delivery of water thereunder, said sleeve is preferably pro# 'vided with inwardly extending brackets indicated at 83, see Figs. 2 and 7, whichrest upon the fitting, 51, and hold the lower edge of the mutller sleeve at the desired distance from the bottom of the tank. This construction is very simple, but is very etlicient, in permitting the water to discharge into the tank without pressure, thus causing it to run in silently, regardless ofthe pressure of the water supply.
The upper part ot' the valve casing comprises a casing member, 61, which is otcylindrical form, and is provided at its lower end with an annular flange, 61a, adapted to receive a follower, G2, provided with interiorly threaded portions to engage the exteriorly threaded portions, 58, ofthe casing member. 53. The valve itselt is formed by a simple disc, G4, of rubber or leather, or other suitable material, having its edges clamped rigidly between the meeting faces of the casing members, G1 and 53, above the valve seat, 59, the said disc being adapted to be forced down into engagement with the seat by a mushroom plug or pin, 65, located in a recess, 61h, in the upper casing member, and having a stem, `6 6,.extending through a hole inthe upper casing member into a transverse recess,l 67, with which said member, 61, is provided. It will Abe noted that the clamping of the marginal. portions'ot the valve disc, 64, between the members ot the casing makesit unnecessary to-provide any stufling box for the projecting stem, 66, as no water eanpass above the valve. ot the mushroom plug, 65, is provided with a 'circular recess, 65a, slightly larger than the valve seat, 59, so that when the mushroom plug is depressed as hereinafter described, the central portion of the disc valve will be clamped between the inner face of this recess and the valve seat, and'delected slightly out of the plane of the other portions ot the disc, thus insuring the positive seating of the valve on the valve seat, and the closingot the water inlet aperture in the seat. The upper portion ot' the Acasing member, 61.is ,provided on opposite sidesof the slot or recess, 67, with two pairs of aligned apertures, 68 and v(38, located at different distances from the mushroom plug, and designed to receive a pivot pin, 69, on which the valve actuating lever or float lever, 70, is pivoted. The object of havingtwo ksets of apertures is to permit of changing thev leverage ot the float lever with respect to the mushroom plug, when this is necessary or desirable. In this instance I have shown the lever, 70, threaded. at its inner end and provided with an internallythreaded sleeve, 71, into which it screws, the said sleeve being drilled transversely to receive the pivot pin, 69, and after the parts are assembled with the pin in the proper pair of register.
ing holes, the float lever, 70, isscrewed up against the pin, as indicated in Fig.' 2, and serves to lock the pin against accidental longitudinal movement. I also prefer to provide the threaded portion of the lever, 70, adjacent to the sleeve, 71, with a lock nut, 72,r preferably in the form of a wing nut, which can be screwed up against the end of the sleeve, 71, so as to lock the parts. into position, and prevent the lever from' unscrewing and releasing the pivot pin, 69.
I also prefer to provide the iioat lever, 70, with an adjustable stop Vto limit its down- .wardmoveine1`1t, so that when the water level falls during va flushing action, the float indicated in this instance at 75', cannot interfere with the operation of the flushing valve, (not shown). For this purpose I conveniently employ an adjustable stop plate indicated at 73, and shown in detail in Fig. 5. This plate is preferably rectangular or polygonal in shape` and is provided with an aperture indicated at74f, surrounding the lever, 7(1), and so located that each of the edges. 78, 73h, 73C and 78d are situated at a 'different distance from the center of thev hole, 74, as indicated by dotted straight lines in `]Fig. ,5. The length of the sleeve, 71, from the vpivot pin, 69, is so calculated that by inserting this stop plate, 73, Y
between the end of the sleeve and the set nut, 72, its lowest edge will: engage a part The lower taceY llt) of' the inlet valve structure, asefor example in this instance the upper face of the follower, 62, and serve as ajstop'tolimit the downward movement-of the'float and float lever. By loosening-the set nut, 72, the stop plate., 73, may be rotated'to 'bring any one of its edges into the bottom position, there.
by forming' an adjustable stop-for limiting .water in the inlet pipe, 50, willraise-'the valve, 64, permitting the water to flow over the valve seat and down through the segmental passages, 57, between the Aseat block, 58. and the walls of [the lower casing member, 53, and discharge through the annular passage, 60, between'the inlet pipe, 50,'and.
the discharge pipe, 56, Iinto the muffler sleeve, and thence silently into the tank. As soon as theflushing valve is closed, Ythe tank is refilled, and as the water level rifsesit lifts the fioat fand float lever, depressing the mushroom plug andforcingthe disc valve upon its seat, so as" to stop further ingress of water. fIn pressing thel disc -valve upon its seat, the lbeveled edges, 59'1, of the seat, and the recess, a, in theplugco-op'erate in `seating the valve 'at the outer edge of the seatrst, thus 'closing off the'supply of v-water silently, and preventing theV prolonged hissing which isfrequently noticed in the closing of inlet valves,
In Fig. 2 of the drawing vthe float lever is 'shown pivoted in the aperture, 68, located at the greater distance from the axisk of the mushroom plug. In a case wherevery high water pressure is encountered and itis desired to aifoid the` fioat and float leverxincreased leverage in closing Vthe inletv valve, the upper member, 61, of the valve casing may be rotated into the vdiametrically opposite posit-ion by loosening the follower, 62, and the float lever rmay be pivote'd in the other p'air of apertures, 68a.
It will be seen that my improved inlet valve mechanism is of very simpleconstruction, and that the parts may be readily manufactured and assembled. As the valve casing is located above the waterrlevel, it is readily accessible to elfect'a repair or replacement by simply removing the top or cover, 2, of the tank, when the follower'can be unscrewed bytheingers, (or an ordinary `without the aidof skilled labor.` vjustment of the stop plate, 73,7will ordinabersv of the valve casing, The part of an yinlet'i'valve mechanism which is most sub- `ject to injury? and wear, is the .valve itself, i `and as-this is a merev disc of rubber: or "ilcatlier,-it. can be 'readily removed and replaced by Vanother similar valve or disc, and y if the householderV does not happen/to have 'suc-h a 'disc furnished by the manufacturer,
adisc can be improvised by cutting it from any suitable piece of Y rubbery or leather, whichmay be conveniently at hand. Should the valve seat become injured 'by the'action of grit in the water or-corrosion from chemical constituents of the water, the lower cas- .ingr member can be unscrewed, and the seat plug, 58, .driven out Yfrom thev bottomnpwardly by means of'a nail or hammer or otherwise, and a new valve seatjblock furnished by the manufacturer canbe inserted,
`sothat my improvedvalve mechanism can be repaired byv any ordinary householder,
The adrilybemade when the device isinstalled and will probably vnot require further adj ust- Y-ment,-but if' such adjustment should be necessary-u it can be readilyy effected by simpl-y -looseningthe' said nut, 72, and turning the plate, 7 3, tobring the proper edge into lowest position.
Where it is desired to provide for an.
after-fill, the lower member, 53, ofthe valve casing is preferablyprovided with a lat-y eralthreaded aperture, as indicated at 53,
in Fig. 6, in which is screwed anipple, 75, providedwith a bore at its outer end large enough to receivea piece'of small-copper Itubing indica-tedV at76.V ,This t'ubing,76, is .providedzwith a rubberwasher or packing ring, 77, surrounding the same, and is engaged by a follower, 7 8, which screws on to the nipple, 75, so as to clampthe washer,
'77, between itV and the -end ofthe nipple and around the tube, 7 6, thus forming what is in effect a rslip joint,.,and obviating the necessity of threading the copper tube,
which necessarily weakens'such a tube and causes it to conveniently break in the threads; `The outer end of thc tube, 76, is
carried above' the overflow pipe, 4, as indicatedinfFig. for eXample,in a well knownk way,thus providingl a smalhstreamfof water which will be discharge through the overflow pipe. to the bowl after the closing of the flushing valve and until the inlet l'valve is closed, and providing for an after-v fill of the bowl.. Where the tank is provided with other means for effecting the afterfill, the lower member ofthe valve casing .may be made without the lateral aperture, 53C, as 'indicated for example in Fig. 2;
