This invention relates to fountain cuspis dors, with particular reference to cuspidors used in the professions, such asdentistry and medicine. I t 5 a The subject matter disclosed andclaimed herein constitutes a division of an application for fountain cuspidors, filed Now-30, 1926, SrpNo. 151,736, patented April 15, 1930, No. 1,754,757.

In the application above identified there was disclosed afountai'n cuspidor of novel construction and possessed ofnumerous advantages over the prior art. .In its simplified and preferred formthe cuspidor-comprised a unitary drainage and-distributing head through which :all of the waterand waste of the cuspidor passed. LA bowl was mounted on the upper end of the head, while the lower portion of thehead engaged with a support housing drainage and water supply assages or conduits,- while a branch ex ten edlaterally and. upwardly fromthe head carrying atumblerbowl and its .asso ciated supply and drainage passages.-

Among the objects of theinvent-ion are: to provi e improvements in'valveconstructions for cuspidors; toprov'ide-in a one idor a supply ordistributing. head of ,a single unitary casting; to reduce the labor formerly necessary in constructing cuspidors; to provide an improved method of forming and assembling valves in cuspidors; to provide the control valves of cuspidors as preformed inserted units; and manyother ob jects and advantages as will bemore ap-. parent as the description proceeds. 1

Before describing the invention in detail it should be noted that among othenitems of expense in former constructionsiof ,cuspidors, was the labor cost in the formation of the ducts, conduits andsimilar water pas sages to and-from the valves controlling the several water supply passages. The former constructions required accurate. machining and drilling, to allow fonwhich castings used were heavy, with thick walls, accounting for appreciable expensefor the material alone, and the laborv cost added to the cost of material formed an. expensive element in the total cost. .In largemeasure both of disposition 'ofthevalves, r

In constructing the cuspidor compactness and economy were among the desiderata, and the cuspidor affords both. In the preferred form of-head, through which all of ceptible to formation by a casting operation.

As soformed, the valves controlling the water supply are pre-formed and mounted in the head in a novel manner, and water supply conduits'fromthe valves to the several outlets are formed by pre-formed tubes cast in the metal of the head. Drainage from the tumbler bowl and from the saliva ejector is into the drainage passage of the head, beneath the cuspidor bowl and its as sociated trap.

The head B, preferably a casting, comprises a hollow sleeve-like bod terminating at the lower end in a threa ed coupling member 16, and at the upper end in a bowl coupling member 17. Both couplingv mem-. bers are preferably concentric with the axis of the head. The major portion of the main:

body of the head is generally annular or cylindrical and is concentric with its axis and with'the coupling members, but at one side is provided with a branch coupling face 18, having threaded openings 19 to receive coupling screws of thebranch, and on another side, preferably. diametrically opposite thereto, the head is provided with a'radial projection 20. The wall 21 from which the projection 20 extends is formed of appreciable thickness, having a substantially plane inner face 22, and the wall 23, contiguous to the branch coupling face, and opposite to wall 21, has also a substantially plane inner face 24, parallel with the inner face'22. The thickened Walls21 and 23' are connected by the curved relatively thin walls 25' and 26, having the irregularly curvedinnersurfaces 27 and 28' respectively. The inner faces 22 and 24', and 27 and 28, form the main drainage passage 29 through the head, and which is generally trapezoidal in outline. The drainage passage 29 thus formed is of substantially uniform diameter from the upper end of the head to well toward the bottom, where an oblong slot 30 pierces the wall 23 frominner face 24 to the surface of the branchcoupling face 18, to permit the passage of drainage waterfrom the branch. Beneath the'slot 30, the area of the drainage passage 29 is decreased by a web 31 projecting inwardly from the severalinner faces of the walls to form the common circularoutlet 32, concentric with the axis ofthe head. It willb'e noted however, that although the common outlet 32 is" concentric with the axis, the major area of the main drainage passage 29 is located laterally of the axis ofthe' head as located by the outlet 32 and coupling members 16 and 17, due to the differing thicknesses of the walls of the head I l For supplying water to the conduits in the branch, tobe described later, conduits 33 and 34 are provided in the head, extendingfrom the thickened wall 21, through walls 25 and 26 respectively, and terminating in wall 23. The conduits 33 and 34 I comprise tubes, pre-formed and curved'so that in position the ends located in wall 21 are arranged in parallel spacedhorizont elati n, nd i Wall. 2 are in s aced relation out of vertical alignment, to permit coupling with conduits in the branch, to be described.

The tubes 33 and 34 terminate in metal valve seat inserts 35- and 36 respectively, with which they are held in proper association during the casting operation, and which form integral parts of the metal walls after such operation. Each valve seat in sert comprises a disc of metal knurled at its periphery as at 37, to facilitate the grip of thec'ast metal thereon, and each has an axial bore 38 andaconcentric valve seat 40 formed on one face. The disc insert is associated with the pre-formed tube prior to the casting operation, and it is preferred to drill a hole 41 part way through the dish insert from the rear face, .close to, the axial bore 38, of such diameter as to receive an end of the benttube to be associatedivith it. The end of the tube is inserted in the hole 41 and held against movement therein as by. means of silver-solder, for instance. This leaves a thin web of disc metal 39 between the open end of the tube and the valve side of the insert, which precludes entrance of cast metal into the tube during the casting operation. This constructioni's preferrediasit enables the use of a valve of restricted size compared with the diameter of the tube throughwhich the; water is to pass. It will be clearrhowever, that it is not necessary to leave the thin web of metal 39 over the end of the tube, but-that the tube may be inserted into a hole drilled all the waythrough-the disc, and a removable element associated with the end thereof during: the casting, andi which isawithdrawn' with thecore, ('notzshowLn). However associated', the tubes- 33 and 3:4'are1held in position with th-e disc inserts of valve seats and3.6, during: the casting, in which metal flows about and embraces the rear face, the periphery and the outer portion of the va-lve seat face of the inserts, as well as the entire tube, but: leaving a cylindrical threaded'bore or chamber 42 adjacent the valve seat-face. Y

The thickened wall 2'1 to'allow for the firm anchoring: and embedding of the valve seat inserts and tubes, with sufficient metalbeyond the valve to permit the firnrsu-pport of an inserted valve stem is of" such 'size as 43, the threads- 44 being formed in the valve chamberor bore 42 to receive: the valve stem. In the form of valve assemblyshown, to form a complete conduit from the. valve chambers to the water supply tubes it is but necessary to drill passages 45 through the thin websof' disc metal over the; ends of the respective tubes, preferably at an angle to thebore of each disc. It will be clear that water brought by passages to be describedto' the rear face of the disc seat of either valve, will pass through the-axi l bore, and if the valve is unseated will flow into the valve chamber, through passage 45 into the tube. It will be understood that as far as the valve construction is concerned it is identical for either tube 33 or 34,'and the tubes are practically the same, except that they are bent in opposite directions, so that tube 33 is embedded in wall 25, while tube 34 is embedded in wall 26. In casting the tubes in position, the ends remote from the valves may be prolonged in wall 23 until practically flush with face 18, and by a subsequent drilling operation they are terminated in tapering threaded openings 33 and 34 in the face 18.

Each valve chamber 42 is closed by a threaded nipple 46 extending thereinto, in engagementwith the threads 44, through which nipple the valve stem 43 extends, the inner end of which carries at 47 a freely rotatable cup 48, in which a resilient valve disc 50 is mounted, arranged for axial engagement with the seat 40. A handle or knob 51 is connected at the outer end of the valve stem. 43 in any desired manner, and the whole valve assembly is rendered watertight by a packing gland. 52, as is well known. The valve assembly applies equally well to either valve controlling the passage of water through the conduits 33 and 34. The control devices, the knobs or handles 51 and a part of the valve stem 43 extend beyond the outer periphery of the head above the radial projection and normal to a plane surface 49 formed by shoulders 49' extending from the wall 21, and preferably in'a horizontal plane. It will be noted that the tubes or conduits 33 and 34 are located and embedded in the walls of the body and do not affect and are not affected by, the clearance of the drainage passage 29.

Depending rom one side of the radial projection 20 is a saliva ejector housing 53, one portion of which is vertical, terminating at the bottom in an ejector tube coupling 54, and axially drilledas at 55 toform a.

drainage passage intersecting at its upper edge as at 57 the upward bend of a saliva ejector passage or conduit 56. The saliva ejector passage is a tube 56 as shown, which is of an inverted and widened V shape, located wholly in the wall 21 and the integral radial projection 20, in which latter it is located laterally of the center, in alignment with thevertical drainage passage 55 in the housing. The outer end of the saliva conduit remote from the axis of the head or body terminates in an ejector housing or bore 59, and the conduit inclines upwardly from the bore until its apex is in substantial alignment with the outer periphery of the head, when it inclines downwardly through the wall 21, terminating in a drilled opening 58 in the drainage surface 22. In forming the ejector condu t, a preformed tube is groove 60 is? provided-in the :inner face 22 as a guide for a drill, and'the end of the tube 'and the' adj acent" metal, (not shown) may bereces'sed by ahorizontalzdrill passed horizontally through the lateral slot 30 in the h8aCl,"WhlGh slot isin-registry with the finished iendiof the saliva ejector conduit as shown. i

' Avalveforthe saliva ejector is formed in the substantial center'of'the radial projection 20 by embedding pre-formed'valve sea-t,-insert.61 inthe projection. This-insert is axially 'bored as at62, and has a concentric seat 63 formed thereon, and is held in. proper vertical position during the casting operation by suitable core means,

(not shown) extending into the bore 62, and preferably for a desired distance beyond the insert to form a passage 69 coincident with the bore through which waterpasses to the valve seat. The insert is held horizontally by some such device as a set-screw-64 ex: tended from 'athreaded opening.65 in the insert, the outer end of which is gripped by portions ofi-the die during the casting operation, and th'e projecting'portion is later removed "as-bysawing untilrthe end of the screw and the surface of the projection20 are substantially flush, infthe finished head.

A valve chamber 66 is formed in the metal cast about the insert, including a threaded bore 67, toreceive a valve68, similar in all respects to' those v: already described. The watersupply passage 69 formed as described or'by suitable drilling, extends through the radial projection and wall 21 but does not enter nor communicate with the drainage surface 22, but terminates. in substantial alignment-with the plane of the rear faces of the valve inserts 35 and 36, at such.point as tointersect the main water supplyduct to be described.

r The saliva ejector tube, and thesaliva ejector valve are thus separated laterally by a wall of cast metal 70, an d communication betweenthemis had by a transverse duct 1 '71-, drilled from the ejector housing 153 to the valve chamber 66. The ejector end of the duct 7lis1arrangedin registry with a lateral opening 72 of the ejector 73, the taperedaxial bore-74 of which terminates adjacent the intersection 57 of the saliva tube and salivadrainage passage 55. The ejector has a threaded rear end 75, for receiving an ejector screw 76, closing the ejector bore 59. With the arrangement described water passing around the valve through the axial bore 69,- enters the valve chamber 66, passes throughduct 71, and isprojected from the ejector tip past or bythe verticalisaliva' drainage conduit towardthe :apex of the tube, and then down topass into the'main drainage passage 29, where it merges with the other drainage material and passesout through the common outlet 32, and in passing exerts suction on the saliva drainage tube in the usual manner. H To supply water tof-the-seatdisc's-35 and 36, two ducts are drilled, as at 88gand 89, from the upper. portion-0f the head hehind each valve seat disc respectively, converging upon the end of the 'water'supply duct 77, at its intersection with the lateral bore 69. The outer ends of these ducts are plugged as desired;
