To all whom t may concern:

Be itfknownrthat I, CHARLES E. SHADALL,

a citizen of the UnitedStates, residing at Milwaukee, in the county of Milwaukee and State of, Visconsin, have 'invented certain newV anduseful Improvements ink Flushing'V and Ventilating Apparatus, .of which the following is a specica'tion, reference being had to the accompanying drawing, forming apart thereof.

',This 'invention relates A'tol apparatus forA flushing and Ventilating water closets, urif nals andthe like.

`The Ymain objects of the invention are t6 cornbine'v in a single fixture, flushing and.y v y l 1 pansloi Chamber 10finto adischarge Scham#v ventilating apparatus; to facilitate installa@ tion andwoperation of the apparatus and generally to simplify and improve the constructionV andbperation '0f-devices of this class;

ment and combination of parts as herein- Y after particularly described and jpointed out ing the invention as applied to awater closet v bowl; Fig.l 2 is a view partly inside eleva'-l tion and partly in vertical section, showing a modification of the apparatus; and Fig.'

3 is a crosssectionon the line 3-.-'3, Fig. l."

Referring to Figs. 1 and', the apparatusv comprises av casing 1, provided 'with a removable cover 2, and containing' a flush valve chamber 8 and an aspirator chamber" il. The chamber 3 is provided with a nor.

mally closedV flush valve 5, which controls` the supply of 'flushing water'to a closet bowl 'c 6, or other fixturewith which the apparatus` is connected, This valve, which'lmay'be constructed and operate in various ways,lis in stemv 7,' freely 'fitting' inf'a socket or guide# 8, depending 'from the cover-2, and y1s adapt- Ved wheureleased, to be elosed'and held the present case, as shown, provided with a' closed vby the 'water pressurev against a seat V9, which is preferablyremovable and' renew'- n able. Within the valve chamberbelow the. valve seat 9 and in alinement therewith, a* cylinder or expansion chamber 10 is formed,

andthis chamber' is provided with a piston ,i Specification of ALetters Patent.

A`spring29,.interposed betweensaid valv'e and the cover, assists the v vaterV piressurey to clo's'e land holdV said,l valve Vupon its seat." A l'self-'centering' spreader' 30,

pivotally l(':onnectedwith vthe'rvalvev 26', isv f i adapted vwhen f shifted; upwardly withy the 'f .opening of saidvalve, to reduce the area of the l jet lopening `24C and' produce vra symmetlect in thev "1 'ric'al "cone-shaped; spray orjet of water,=' 'Y whizh is most effective forentraining airI -with itfthrough the tube'or' conduit 21.. The spreader also serves to dislodge any dirt orforeign matter which may be caught' or col.V

'et'Yopen-ingf-and to keep said A lever 31, which may be operated byany suitable means, such as a handle 32, is pivot- `supply pipe 33, which'leads into the ush valve chamber 3 above the valve 5, a foul air Y d'scharge pipe 34, which leads out of the aspiratorl chamber 4 into which the tube or conduit 21 opens at its lower end above the water sealed discharge port or opening 23,

v andtwo pipe fittings or couplings and 36,

which connect the discharge chamber 19 and the lower end of the passage 22, with separate passages 37 and 38, which communicate .lwith the upper 'part of the closet bowl 6,

the passage 37 leading into the flush rim 39 ofthebowl The passages 22 and 38 and fz the pipe iitting or coupling 36, serve both to conduct foul air from the bowl into the aspirator chamber, and to discharge the wa-l ter'usedtooperate the aspirator into the bowl. f

1n the operation of the apparatus as thus far described., when the bowl 6 or other fixture is in use, the lever handle 32 is depressed, thereby opening the valve 26, while the valve13 remains closed. Water is thus admitted through the port 26, chamber25V and opening 24, into the upperpart of the aspirator chamber 4, lthe spreader 30 being drawn upwardly7 into the opening 24 and for-ming therewith a conical jet or spray of water in the tube or conduit 21. Foul air is thus drawn from the bowl 6 or other fixture through'the passage 38, pipe fitting 36 and passage 22, and entr-'ained with the jet or` spray throughL said tube or conduit into the 1 i lower part of the chamber 4, 'as indicatedby arrows in Fig. 1. In the lower'part of lthe chamber 4 the air separates from the water and is discharged through the pipej connection 34, while the w-ater is `discharged through water sealed port 23 into the llower part of the passage 22,v and {iows thence through the pipe tting36 and passage 38 into the bowl. v The bowl or other xture is thus effectively ventilated while it is in use. Afterward, the lever handle 32 is momenn vtarily lifted, thereby closing the valve 26 and l yopening the valve 13. Water is admitted from the supply connection 33 through thepassage 12 into the chainberlO below the piston 11, the piston is forced upwardly'andthe valve 'liited from its seat. Waterthen rushes from the upper part of the chamber 3 through lthe port uncovered by the valve,A

into the lower part of said chamber, thence through the passage 20, chamber 19, pipe ii'tting andy passage'l?, into theiiush riin 39, from which it is discharged in a spray or iihn and flushes the bowl. K

Nat-er escaping from lthe `chamber 10 through the restricted-passage 17 when the valve 13 is closed, allows the piston11 to descend and the valve 5 to close gradually according to the adjustment of the regulating valve-18, by which the duration vof 'the iushing operation is determined. V V

The operation of the modified form of the apparatus shown in Fig. 2 is substantially the same, except that water rom both the chambers?) and 4 is discharged into the bowll or other iixture, and airis'drawn therefromk through a single connection 35. r[his form or' they apparatus is applicable to a 4bowl or other fixture of the ordinary construction having a flushing connectionsuch as 37, as shown in*` Fig. 1, but when the discharge from the opening or 'openings from the :flush .i rim or other. connection is quite restr1cted,'a

bowl or other fixture of special design, having a separate passage or connection 381er the discharge of water from the aspirator and the withdrawal of foul air from the bowl or other fixture, is desirable, as shown in Fig.- 1. With a bowl or iixture of such construction, the passage 22 separated Y from the discharge passage or chamber of in Fig. 1. 1 Y

. Various changes in the details of construcvsa' the flush valve by a partition 40', as shown tion and arrangement of parts may be 'made v without materially affecting the operation of the apparatus and vwithout 'departure from the principle and scope of the invention as defined in the following claims.
