INCORPORATED; OF WATECRBURY, CONNECTICUT, A CIYRCPORATION` y WASTE-AND ovERFLoW FITTING Application filed I|3`ebruary 29, 1932. Serial No. 595,705.

This invention relates to an improved waste-and-overiiow fitting, and particularly to fittings of the type referred to for use in connection withbathtubs, though not so limlted; j

One of the main objects of my present invention is to provide a waste-and-overflow fitting of superior neatness, f combined with ease and convenience of operation.

A further object of my invention is to provide a fitting of the character referred to, in Vwhich the' operating-mechanism for the waste-control valve maybe readily and conveniently adjusted.

With the above and other objects in view,

as'will appear from the following, my .in-`

vention consists in a waste-and-overflowV fitting of the type Vreferred to, having certain features of construction and combinations and arrangements of parts as will be hereinafter described and particularly :recited in the claims. i. 1

In the accompanying drawings: l Fig. 1 is a broken face View of the overflow-portion ofmy improved fitting, shown as applied to a bathtub, which latteris broken away; f l Fig. 2 is a broken view fin vertical central section, showing the complete fitting applied to a bathtub, which latter is broken away;

"Fig V3 is a broken, detail, sectional (view taken on the line '3--3 of Fig. 2; Fig. 4 is a transverse sectional view taken on theline 4 4 of Fig; 2; Fig. 5 is a face view of detached; and

Fig. 6 is a perspective view of the'unit comprising' the face-plate, operating-member, and associatedparts, detached. f

Thel particular waste-and-overflowv fitting herein chosen for the illustration of my invention comprises a cast-metal overflowhead 10 having the general form of an elbow, and provided in its lower end with a socket 11, into which the upper end of an overflowtube 12 is adapted to be solderedor-otherwise secured. The forward face of the head 10 is recessed `to provide an annular gasket-seat 13, into which is seated a ring-like gasket 14, adaptedto be compressed between the said clamped, so to speak, between the overflow-` opposite sides of thecenter thereof, and into the overflow-head,

seat and the outer surface of the `wall 15 `of a bathtub. v i y The head- 10 is provided adjacent the gasket-seat 13 with a pair of inwardly-extending lugs 16-16, respectively'projecting into the L-shaped hollow interior 17 ofthe said head, and each formed with'a threaded. perforation 18 for the reception of bindingscrews as will hereinafter appear.

Located against the inner face of the wall 15 of the bathtub, axially `in line Ywith the open `forward face of the overflow-head'llO, is a domical face-plate 19 provided on its rear face, adjacent its edge, with ythree (more or less) spacing-lugs'QO whichserve tofhold the said face-plate in spaced relationship forwardly'. of thefinner face of the bathtub-wall 15, so as to create a substantially-annular overflowpassage 21 therearound, whichcommunicates with the L-shaped interior 17 of the said'head` 10,-through a circular opening22 vin the bathtub-wall 15 and acorresponding' opening 23 in the gasket 14.

The bathtub-wall 15 and the gasket 141are head 10 andthe face-plate y19 so as to provide a watertight joint, by means of a pair kof clamping-screws 24-24 passing rearwardly through ythe face-plate 19 on the 'respective so the threaded perforations `18 in the lugs 16--16l of the head 10. The perforations 1n the face-plate 19 through which the clamping screws E24- 24 pass are the'only perforations or breaks insmoothness of the exposed surface of the face-plate. The heads of the clamping-screws 24--24Y and the perforationsare complementarily lformed so that when the screws are in position the exposedsurfaces of their heads and the exposed surface of the face-plate form one substantiallysmooth and unbroken surface easy to clean and neat in appearance; l

The rear face of thel face-plate 19 is provided with an axially-located rearwardly-extending boss 25 havinga rearwardly-opening threaded socket ,26 receiving the. threaded stem 27 of a screw-stud '28'upon whichis mounted, with capacity for lateral` oscillation, a wastevalve-operating membengener'- ally designated by the numeral 29. The said operating-member 29 is provided at its forward end with a relatively-slender lever-arm 30 extending radially outward through the upper portion of the overflow-passage 21, and adapted to swing laterally between .the two uppermost of the spacing-lugs 20, which( latter also acts as stops for the said lever-arm. The lever-arm just referred to is provided at its outer"V end with a forwardly-extending finger-piece 31 toafford a convenient grip for the manipulation of a waste-valve, as will hereinafter appear.

The rear end of the operating-member 2,9 above referred tois provided with a radiallyoffsetting arm 32 mounting, in its outer end,

Va*rearwardly-extending stud 33 over which the perforatedupper end of a coupling-head 34is slipped and retained in place on the said stud by means of suitable means; n The coupling-head 34 just above referred to is formed withfan axially-arranged downwardly opening-threaded bore 36 receiving the ,threaded upper end of a' screw-eye 37, the eye`38 ofwhi'ch is connected, by means of a pair of links39 and `40, to a bridge-plate 41 formed integral with andextending diamet`` rically;V across the upper end ofV a tubular waste-valve 42,0pen at its lower end as shown andopen at its upperend save for theY spiace.

f occupied by the slender bridge-plate 41 y The waste-valve 42 and its housing 43 may thereat. Y Y Y .The said-waste-valve 42 is adapted toreciprocate within a waste-valve-housing 43 and is rovided on its 4lower outer edge with a conicaily-shaped seat 44, vadapted to coact with a similarly-shaped seat 45 formed within thesaid housing 43 adjacent the lower end thereof. Y Y v be of any approved type, but ashereinshown` thefsaid housing'is of T-shaped form, having an 'upwardly-extending arm 46 `receiving theV lower end of the waste-tube 12, and having a lateral arm 47 connected vto a horizontal tube 48 leading to the drainage-opening (not Y shown) of the-bathtub. The lower arm 49 of the housing 43 is internally threaded as l at 50 for being coupled-to a. drainpipe.

From "the foregoing, it will be seen that the waste-valve 42 maybe raised and lowered with referenceV to theseat 45 inVits-housing 43by swinging the lever-arm 30 from side to side between the two upper spacing-lugs 20, and should the water-level in the bathtub riseunduly high, it. may` drain outwardly through the overflow-passage 21 andinto the overflow-tube 12, and VYthence throughthe tubular waste-.valve 42 for ultimate drainage through asuitable waste-pipe.

` Inthefaccompanying drawings, the wastevalve`42 is'shown in itselevated position so as-to lpermit the bathtub vto drain outwardly through thewaste-tube 48, and'it will be a Cotter-pin' 35 or other V130 toyswingjtouone side or theother of a vertical position, to thus insure definite off and, on ,-positions; for the wastevalve 42, the under face of the operating-member 29 is formed with a'cylindrical recess 51 housing a helical spring 52, 'against which is seated a? detentplunger 53 projecting downwardly for yielding engagement with the upper surface of a cam-plate 54 extending rearwardly from the rear face of the faceplate y19 withwhich it maybe formed'integral if desired, 'o1-'secured thereto byy solder,

brazing or otherwise, as shown.

#By sfo arranging the partsthat theY leverarm 30 `or its equivalent operating-member extends' radially outwardffrom behindl the facelplatel'19,-not only is a neat and attractive appearance obtained, but'the absence of pivots, etc.,"on vthe front face of the said faceplate facilitates the maintaining o'f the exposedportionjfof the overflow-fitting in a clean andv attractive condition.

Furthermore, by mounting .the operatingmember 29 on the removable face-plate 19,

the 4screw--eye137 may be readily. adjusted to in turn adjust the position of the valvey 42, removing the clamping-screwsg24 and drawing the Vface-plate 19 outward so as to bring .the screweeye 37 and the coupling-head 34 within reach Vfor screwing 'the former upward or downward in the said coupling-head as may be required; ,v

` It will beV understood by those skilled in the ',art'that my invention may assume varied physical forms without departing frommy- Y inventive concept and I, therefore, do not limit inyselfto the specific.embodimentherein chosen for illustration, lrbut only asindicated-in the appended claims. l
