16 Claims.

My present invention relates to defecators particularly of the lateral outlet type.

The invention is applicable to defecators inclusive of water closet bowls, urinals, and hospital and other sinks, dental, medical and other sanitary bowls, and other receptacles, a-dvantageously having an outlet at a lateral side, and provided with suitable means for the supply of water or equivalent effluent, affording under sanitary conditions a mass of fluid for the well portion of the defecator, serving to receive solid and/or semisolid and/ or fluid matter to be evacuated, 'and for the further purpose of flushing the defecator to discharge such flowable mass into a soil pipe or equivalent, the stated parts being coordinated to effect the respective operations under the condition of substantial absence of sound.

Embodiments of my invention may be generically classed as of the type frequently referred to as the wall-hung type, but such nomenclature as may be applie-d to my invention is indicative merely of the adaptability of embodiments of my invention to be positioned at or approximate a wall, since, as appears more fully hereinafter, defecators embodying my invention may be positioned at any location independently of the location of a wall and may be suitably supported othe than by or in proximity to a wall.

Marked advantages are possessed by embodiments of my invention by reason of the operation of the discharge by water and air pressures and water and air momentums effective conjointly during the discharge stage. By reason of such coordination of water and air pressures and of water and 'air momentums the amount of water require-d to effectuate the discharge is reduced to a minimum. Furthermore, defecators embodying my invention `may be operated at minimum pressure of water or other supplied eiiluent.

Such coordination of pressures and momentums respectively exercised by the air'and the effluent bestows upon embodiments of my invention the optimum quality of silence in operation. Essential characteristics of preferred forms of my invention reside in imparting by the supplied eliluent to the after-lill a vortex movement and conjointly therewith an upfiow movement through the trapway to elfect the discharge of the contents of the bowl. Such vortex movement creates a momentum of the fluid mass within the well of the bowl, a component of the force of such momentum assisting the force of the upiiow movement through the trapway, attended by the lowering of the central area of the fluid mass within the well and resulting force exercised by the downwardly directed current of air, such central lowering of the fluid mass effecting positive force upon matter contained in and including all floating matter toward and through the intake and upwardly of the trapway.

Further features and objects of the invention will be more fullyV understood from the following detail description and the accompanying drawings, in which Fig. 1 is a top plan view of a preferred form of my invention.

Fig. 2 is a vertical central section-a1 elevation of Fig. 1.

Fig. 3 is a vertical elevation of Fig. 1 as viewed at its rear side.

Fig. 4 is a detail elevation on the arcuate section line 4 4 of Fig. 2.

Fig. 5 is a detail sectional view on line 5-5 of Fig. 2.

Referring to the drawings, the bowl I0 and the coordinated parts are representative of any suitable form of defecator adapted to my invention.

The bowl IIl is shown comprising generically an upper portion II and a lower or well portion I2. The normal level of. the mass of water I3 or other matter-receiving and effluent iiuid, known as the after-fill, is indicated at I4. Such mass of fluid serves as the trap sealing fluid.

Suitable provision of means are incorporated in the bowl aifording an initial mass of water or other eflluent serving as the after-fill for receiving any solid and/or semi-solid and/oriiuid matter, and further providing upon the supply of the eilluent to effect the discharge of such flowable mass, such provision of means being embodied in the appurtenant parts of the bowl to be wholly operative at minimum pressure and minimum quantity .of the supplied effluent, and utilizing the momentum of the eifluent conjointly with engendered currents of air to impart silence during the period of discharge.

Such provision of means includes a trapway or upflow leg indicated at I5 and a dam or weir 1 I6 effective to seal a portion of the mass of the eiiiuent in the trapway I5.

Such up-flow' leg I5 is afforded by the inwardly disposed ledge I8 extending downwardly toward the well portion I2 of the bowl, its terminal portion I8a being disposed in predetermined relation vertically and horizontally with respect to the central area of the well portion I2, as appears more fully hereinafter. The upper rearward portion of the up-leg I 5 is defined by the septum I9 terminating in the wall formation of the discharge opening 20, for the reception and securement therein of a suitable evacuator 2l. Any suitable type of. connection between the receiving end 2Ia of the evacuator 2l and the wall formation 20 of the discharge opening of the up-ow leg I5, may be employed.

The stated ledge I8 extends upwardly as indicated at I8b to serve as a septum to define one side of the main water channel 22, the inflow port 23 of which may have any suitable wall formation adapted for a connection with any suitable supply of water or oth-er eiiluent, such as a gravity water tank or a nipple provided with a flush valve, for supplying water from a domestic or local pressure water line, pressure tank, etc.

Such main water channel 22 is defined at its lower portion by the stated septum I9. The upper or top wall 24 of the main water channel may be afforded by the rearward horizontal ledge or shelf of. the bowl.

The effective contour of the up-ow leg I5 may be of substantially uniform circular cross-section, as shown; such cross-section may vary in relative cross-section from its intake to its outflow, as is set forth in my co-pending application, Serial No. 749,069, led Oct. 19, 1934, entitled Defecators.

The bowl proper may be supported in the indicated substantially horizontal position in any suitable manner. Advantageously, the bowl is supported by attachment to a wall indicated by the line 25, the material of the bowl proper being extended for such form of support, viz., by a rearward vertical web 2S extending to a vertical back plate 2l, which extends substantially parallel to the face of the wall 25 and substantially normal to the web 26.

The upper bowl portion Il is preferably of multi-conical formation, as shown; however, certain essentials of my invention are not limited to the illustrated form.

Preferably, the uppermost portion IIa inclusive of the web I8?) is inwardly concave, receding from the vertical plane with respect to the effective area of discharge of the rim openings 28 provided for in the rim formation 29, the effectiveness of such relationship being set forth hereinafter. The rim formation 29 includes the rim channel 3U which extends about the top of the bowl and has an intake port 3| communicating with the main water channel 22.

An essential feature of each rimopening 28, in its preferred formation, includes the outwardly divergent effective discharge in a direction toward the outer face of the bowl with respect to the vertical, whereby any matter possibly deposited on the inner face of the wall, particularly the back wall I8b of the upper wall portion IIa of the bowl, is subjected to a quasi-chiselling action by the jet of water discharged through the rim opening. Such preferred form of rim jet discharge may be employed for the forwardly disposed rim openings 28, and/or at the sides of the bowl.

The rim openings, particularly the sets thereof disposed about the sides of the bowl, further, are directed to cooperate with the vortex jet of the main discharge flow means of the bowl, later described, to initiate and/or enhance such vortex movement of the flowable mass I3.

The vstated provision of means for positively eliminating noise during the stage of discharge of the bowl comprises channel means, shown in the form of two oppositely disposed channels 32 respectively having intakes 32a communicating with the main water channel 22 and outflow ports 32h, the latter communicating with the upow trap leg I5. Advantageously, such channels or ports 32 are formed in the septum I9 and side walls of the up-flow leg I 5, thus locating the outow ports 32h to be directed upwardly relative to the eiiluent I3 disposed initially dormantly within the up-flow leg i5.

Such channel means 32 serve also for the flow of the efiiuent to and through the vortex jet 33, which may terminate in a nozzle formation, the same being directed, as appears in Figs. l and 2, to maintain a vortical movement of the mass of the fluid I3 within the bowl, say, in a counterclockwise direction.

It will be observed that the out-now port or ports 32h and the vortex opening 33 are located within the mass I3 of the eiliuent, that is to say, below the normal level I4 of the same; the extent of submersion and the area and arrangement of opening of the channel out-ow port or ports are determined by the desired degree of up-flow effect to be imparted to the portion of the owable mass I3 within the trapway I5. The extent of submersion and the area and arrangement of opening of the vortex jet 33 are determined by the desired degree of vortical movement to be imparted to the portion of the mass I3 within the lower portion of the bowl I0.

Preferably, as shown in the drawings, each outflow port 32h extends at opposing side walls I5a, I5a, see Fig. 5, of the upflow leg I5 and opens out over an elongated area, its mean direction of opening being substantially in alignment with the mean upward direction of the upflow leg I5.

The bowl and the stated component parts may be of vitreous material suitably molded and 'i otherwise treated, or of cast metal or other proper material, enamelled or otherwise appropriately surfaced and/or suitably treated. The defecator illustrated in the drawings, and to scaled dimensions, has been designed for manufacture of porcelain, suitable provision being made for the proper coring of the channel parts, allowance for shrinkage of the material ensuing during the baking stage, etc. The stated preferred form of the rim openings is conveniently had by drilling through the uppermost wall of the rim 29 during an intermediate baking stage, the thus formed drill openings in the upper Wall of the rim 29 being later plugged with the porcelain-forming material to eradicate the same in the final status of the bowl.

Coordinated with such up-ow discharge means 32 I provide an evacuator 2I, set forth more particularly and claimed per se in my copending application Serial No. 4,620, filed Feb. 2, 1935, entitled Evacuators, now U. S. Patent #2,055,490, granted September 29th, 1936.

For the purposes of the present invention, such evacuator 2| in construction and function possesses the following essentials: an upper section 2lb, conveniently also forming the upper elbow section of the evacuator, a relatively cross-sectionally restricted downwardly extending section 2Ic, and a lowerly eflluent curtain forming section 2| d. The outtake section 2Ie is adapted to be connected in any suitable manner to a Y-fitting or other laterally opening fitting leading to a soil pipe, waste pipe, etc.

The evacuator, as above described and as shown in Figs. 1 and 2 of the drawings, has a resulting general Z-formation. The lower elbow formation 2Id and therewith its outflow chamber 2Ie may be angularly related to the stated upper sections of the evacuator as desiredl viz., at a 45 angle as appears from Fig. 1, or lat a 90 angle, or at a Zero or any intermediate angle, depending upon the relative location of the Y- or other pipe with pressureand with minimum volume of the efflu` ent. 'I'he vortical movement effected bythe jet discharged through the vortex opening 33 is conjoint in its action with the jets directedthrough the ports 32h, in effectingv an up-ow movement of the ilowable mass through the trapway I5, thus utilizing the co-timed forces of the pressure and volume of water supplied as the effluent and those engendered by the currents of air, coupled with the momentum of the owable mass created by the stated vortex movement andthe stated upflow movement.

In the operation of the practical embodiments of my invention, such conjoint action takes place without substantial rise of the mean level of the flowable mass within the well portion of the bowl; the displacement of the flowable mass by the upflow jets emerging through the ports 32h` co-acting with the vortex movement effects in actual operation definite lowering of the level of the cen tral portion of the flowable mass within the bowl, and consequent current of air directed over the fiowable mass within the bowl downwardly toward the intake of the up-ow leg.

Such displacement upwardly through the upflow leg I5 causes the flowable mass to pass over the dam I6 and weir 2Ifrof the. evacuator. The preferred formation of the Yevacuator as is set forth in my aforesaid co-pending application, embodies a Weir portion at 2 If which is substanv tially iiat, thus providing a curtain of the flow-v able mass from and downwardly of the Weir, the

ilowable mass then entering the relatively re--yV duced section 2 I c of the evaouator. Such restriction of the area of the flow brings about the relative rise of the flowable mass above the dam and above the Weir 2 if, thus creating a quantity of the flowable mass within the upper or elbow section 2lbl for i effectually sustaining 4siphonic 'action through the evacuator. Such rise of the flowable mass also causes entrainment of air originally in the bulged or elbow formation of the upper section 2 IU, a portion of the air remaining `therein during the transit of the siphonic discharge. Access of air through the discharge opening 2Ie of the evacuator during the siphonic action is positively precluded by the curtain of the flowable mass arising from the'ow of the flowable mass through the downwardly extending intermediate section 2Ic toward the lower elbow or pool section 2Id, the level of the pool serving to co-act by restricting the effective extent of opening through :A the lower elbow, and further by splashings of the able mass within the well reaches or is below the edge Isa of the ledge I8, that is to say, when air enters the up-leg I5 and passes to and withinthe upper orY elbow section 2Ib of the evacuator, and thereupon breaking the siphonic action. The inflow of such breaking air is enhanced by the air under sub-atmospheric pressure within the upper elbow section durn the stage of siphonic passage.

The jets discharged through the rim openings 28 serve the conjoint purposes of scouring the sides of the bowl above the level of the flcwable mass, and to enhance the vortical movement of the flowable mass within the bowl. Upon the cessation of the siphonic action, the water above the dam IS returns through the trapway I5 into the well, to ser-ve partly as the after-fill; the remainder of the after-fill and trap sealing fluid is furnished by Water through the channel means 32, which operation is noiseless as compared with the supply of the after-fill falling from the rim openings.

The above stated jet formations and consequent displacement and movements of the flowable mass, inclusive of those of the water or other eiiiuent, are thus positively provided for without attendant noise. Further, the flow of the owable mass inclusive of the continued supply of the Water or other eiiluent is had in the absence of noise. Toward the close of the stage of siphonic passage of the iiowable mass, by reason of the stated vortical movement and consequent lowering of its central area, air is entrained to` more or less extent with the eiiluent up-ow through the trapway I5,'thus gradually increasing the pressure of the sub-atmospheric pressure air above the dam I6, thus precluding the usual gurgling sound necessarily inherent in the construction and operation of devices of this character.

It will be noted that the rim openings 28 eX- tend downwardly, thus providing for complete self-draining of these openings. Such arrangement also positively avoids the entrapping of air in the rim channel and/or the rim openings, with resulting operation of the same devoid of noise or other-sound.

It is preferable, as is shown in Fig. 2, to locate the central area I2a of the well I2 of the bowl to be disposed substantially vertically below'the lower edge IatA of the ledge I8, which provision of means functions to locate solids and the heavier semi-solids within or substantially within the intake orifice of the up-flow leg I5 in advance of the flushing stage of the defecator.

As appears from the disclosure herein, the faces of the interior of the'bowl above the well proper of the bowl are substantially smooth and of general conical contour solely increasing in effective radius upwardly without increase of the prior art rate of increase of the radius, to thereby avoid the vortex jet 33 and aided by the rim jets 28,

such vortical movement effecting a lowering of the level of the central portion of the mass I3 within the bowl proper, whereby such fioating and lighter semi-solid matter are positively displaced in a radially inward, downward direction toward the intake orifice of the up-flow leg I5.

It will be observed that the port or ports 32a of the channel means leading to the vortex jet opening and to the trapway upow jetl communicate with the main chamber 22 at a location below that of the port 3| leading to the rim openings, thus insuring initiation of the vortical movement and of the upilow movement through the trapway at the beginning of the flushing period.

Preferably as shown in the illustrated embodiment the port or ports 32a are located at the lowermost level of the main chamber 22 to impart maximum force expressed in vortical and/or upflow movement in the use of any given quantity of water supplied to the main chamber, and further to insure positive drainage of the main chamber, the channel means 32, and the jet openings 33 and 32h to prevent breakage due to freezing.

Preferably, the evacuator or other discharge means of the bowl is connected to the out-take of the up-ilow leg or trapway, independently of the support of the bowl proper relative to a wall, supporting chair or the like, such as is set forth in my co-pending application, Serial No. 48,860, led November 8th, 1935, entitled Plumbing connection.

As is illustrated in deatil in the drawings, the ports 32h are located toward the entrance of the upflow leg I5, laterally opposite to one another and symmetrically positioned relative to the mean longitudinal axis of the upflow leg I5; further, as appears more prominently in Figs. 1 and 4, planes passing vertically through the axes of the respective ports 32h lie at an angle to one another and intersect one another at a location proximate the dam I6, whereby the effluent ejected through the ports B2b combine with one another effectively in the movement of discharge of the contents of the well portion of the bowl into and upwardly of the upflow leg I5 and over the dam I6.

commercially produced embodiments of my invention operate efficiently with a supply of water at the low head of six inches and at the low flow volume of four gallons, delivered, for example, from a regulation open flush tank; such embodiments of my invention operate also highly satisfactorily at three pounds pressure and correspondingly reduced rate of flow of water furnished by a suitable supply under control of a regulation pressure valve.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
