' 5 Thesubject matter disclosed and claimed herein constitutes a division of an application for fountain cuspidors,led Nov. 30, 1926, Ser. No. 151,735. j

' In the application above identified there was disoloseda fountain cuspidor of novel construction and possessed of numerous adprior art. plied and preferred form the cuspidor comdrainage and distributing Waste of the cuspidor passed. A. bowl= was mounted on the upper'end of the head,while the lower portion of the head engaged wit asupport housing drainage and water supply passages or conduits, while a branch eX- tended laterally and upwardly from the head carrying a tumbler bowl and its associated supply and drainage passages.

Among the objects of the invention are; to provide a cuspidor of efficiency and compactness; to provide a cuspidor which issilent as a drainage; to provide in a cuspidor a supply or distributing head ofy a single unitary casting; to provide in a cuspidor al unitary element through which all of the supply and drainage fluid passes; formerly necessary in constructing cuspidors; to provide a cuspidor of decreased weight without adversely alfectingits strength and with an enhancementof `its attractiveness; to provide 'an improved and simplified coupling joining twoparts' of the leaks; and tov provide a lcoupling enabling the quickand easy joining of a distributing head and a pedestal or like support regardless of slight misalignmentsfthat may exist in the elements; l

`and many'other objectsV and-'advantagesas will be more apparentas the descriptionl proceeds.` j Y y 1n the accompanying drawing the ,figure represents a vertical In its Asim- Y h head.

cUsII'DOR Divided and. uns application filed serial no. 390,459. 4 Y Y unitary drainage and distributing head and that a branch'D diverges from the head B. The assemblyis arranged for mounting .upona pedestal or support A, in which are 'the water supply and drainage conduits to' be described.

The headl B, preferably a casting, comprises a hollow sleeve-like body, terminating at the lower end in a threaded coupling memd ber 16, `and at the upper vend ina `bowl couf pling member 17. Both .coupling members are preferably concentric withthe axis of the The major portion of the main body cylindrical and is concentric with its Vaxis and with the coupling members, but at one side is provided with a branch coupling face 18, having 19 to receive coupling screws of the branch, andy on another side, preferably diametrically opposite thereto, the head is provided with a radial projection 20. The wall 21 from which the projection 20 eX- tends is formed of appreciable thickness, having a Vsuba'stantially plane inner face 22, and the wall 23, contiguous tothe branch couling face, and opposite to wall 21, has'a'l'so a substantially plane inner face 24,' parallel 21 and 23 are connected .by .curved relatively thin walls. The inner faces 22 and 24, with the thin. walls form the main drainage 29 through the head. yThe drainage passage 2.9

thus formed Vis of substantially uniform d1- ameter-from the upper end ofthe head to well toward the bottom, .wherean oblong slot 30 pierces the wall 23 f rom inner face 211 to the branch coupling j face, 18, to permit the ypassage of vdrainage water from the branch. Beneaththe'slot 3,0, the area of the drainage passage 29 Vis decreased by a web 31 projecting inwardly from the several innerfaces of the walls .to form kthe common circular .outlet 32, vconcentric with Itvwill be lnoted however, thatV although branch and support, disclosing the disposil' carrying at its upper end a cuspidorjbowl C, v

l The thickened walls Y The common drainage outlet 32 is VWasher 97, which `101, arranged for simultaneously en concentric with the axis, the major area of the main drainage passage 29 is located laterally of the axis of the head as located by the outlet 32 and coupling members 16 and 17, due to the differing thicknesses of the walls of the head.

The main water supply pipe 13 in the pedestal has a threaded end 13', arranged for insertion in the threaded bore 7 7 in the bottom face of the distributing head B.

At the lower end of the head B, the web forming the common outlet 32, may if desired, ,be prolonged to form a tap-ering discharge tube 91, although this is not essential to the proper functioning of the assembly. arranged for connection with the drainage conduit 14 in the support in a novel and useful manner. The upper end of the drainage conduit may be anged direct-ly, or through the attachment of a nipple as shown, in which a tapering barrel or tube 92 is spun into a flange 93 at its larger end,and at the smaller end has an internal shoulder 94, and a lower restricted hollow shank 95. The hollow shank is arranged for soldered connection in the end of the drainage conduit 14 so that the nipple forms a substantially integral prolongation of the conduit. The flange 93, is of such diameter as to seat uponthe lower face of the coupling member 16, and has one or more openings 96, through which the water supply pipe 13 is arrangedY to extend, and

which openings are spaced far enough from the inner surface of the barrel to afford a circular seating surface on the flange, arranged for abutting engagement with a shoulder 89 formed on the lower portion of the headin the plane of the lower face of the coupling member 16. This may be formed onV the discharge tube 91 if that is provided. A may be resilient, is seated upon the shoulder 90, and is engaged by the seat portion of the flange adjacent the barrel when the head is placed upon a support, at

which time the outer periphery of the flange is engaged between the coupling members of the head of the support, and which engagement effects axial distortion of the flange so that a funnel shape is assumed by the nipple, with consequent vertical pressure on the washer 97, to insure a water-tight joint between the common drainage outlet 32 and the discharge conduit 14. A firm engagement of the head B upon support A is had by the application of a nut coupling element 98, having oppositely threaded portions 10() and @aging the oppositely threaded coupling members 16 and 12, and rotated by a wrench, (not shown) engaging suitable Spanner openings (not shown). The assembly will be clear, and it will be noted that considerabley flexibility is had about the discharge or drainage outlet without effecting its water-tightconnection,

.outlet means and initially engageable with the washer but not with the coupling member, said flange adapted for engagement with the coupling member and for resilient distortion by such engagement to impose pressure on said washer. y

2. ln a. cuspidor, a drainage head including a coupling member and an axial outlet extension, a nipple having a flange, the head havlng a shoulder in proximity to the extension,

a resilient washer engaged by the shoulder and compressed by the inner portion of the flange of the nipple when the periphery thereof is forced into Contact with the coupling member.

3. ln a cuspidor, a unitary drainage and distributing head having a substantially Vvertical drainage passage terminating in a delivery outlet, a coupling member formed on the head, a support upon which the head is mounted, a drain -pipe housed in the support in registry withthe outlet, a shoulder being formed on the head adjacent the outlet, a flanged tubular nipple connected at one end to the drain pipe, the outer periphery of the flange engaged between the support and the coupling member, a washer interposed between the inner portion of the flange and said shoulder to space the outer periphery from the flange away from the coupling member and compressed by the engagement of the periphery of the flange with the support and coupling member, and forming a resilient connection permitting restricted movement of the pipe.

4. ln a cuspidor, the combination with a support, of a drain pipe extending through the support, a flexible connection having a tapering barrel connected to the drain pipe and having a flange, a drainage element terminating in an axial projection and having a shoulder, bearing surfaces being formed on the element and the support and spaced from said shoulder in their assembled position, and gasket means interposed between the pipe flange and the shoulder and constricted therebetween by pressure on the flange from the cooperating bearing surfaces, the axial projection arranged for insertion in the'tapering barrel of the connection and to discharge into the drain pipe despite slight displacement of the vpipe from its position in alignment with the extension. v

In a cuspidor, the combination with a unitar f drainage and distributing head, having a pedestal coupling member, and a drain-v age outlet projecting below the member, water conducting means disposed in the head, a support, drainage and water supply pipes housed in the support, of a tubular flanged gasket having an opening in the flange and engageable with the drain pipe, a head coupling member carried by the support arranged to engage the flange of the gasket, a tensione element engaged between the fiange and the head and spaced from the opening in the flange subjected to pressure when the head is mounted on the support due to distortionV of the i'iange, said water supply pipe passing through the opening in said flange.

6. In a cuspidor, the combination with a drainage head having a drainage discharge opening and a coupling member, a support engaging the coupling member, kof a drain pipe in the support in registry with the opening and having a flange, a washer engaged between the ange and said head and forming a tight joint about said opening by pressure transmitted through the flange when the element and support are assembled.

7. In a cuspidor, an element having two bearing surfaces in a plane, a support engaging one surface, a drain pipe having a flange engageable between the Vsupport and the said surface, and means compressed between and making a water tight connection with the flange and said other surface when the element is assembled with the support.

8. ln combination, a head having inner and outer spaced concentric bearing surfaces, a ccmpressible washer mounted on one surface, a flange engaging spaced from the other of said bearing surfaces, and toward said last mentioned bearing surface and thereby to distort the flange' so as to impose sealing pressure on said compressible washer.
