A bell-shaped portion 48al of the housing of the valve 30 is secured to dinally disposed partitions I 8 is located in tube I I and a continuous partition I9 centrally arranged the outer face of the ñange 35 as by a plurality of screws 35a and a short horizontally disposed within and extending lengthwise through the upper portion of the inlet portion members I3, the full length Iof the intermediate portion I4, cylinder 4I is carried by the bell-shaped portion 48a. A flexible diaphragm 42 is clamped around and nearly the full length of the outlet portion its outer peripheral edge between the iiange 35 and the base of the bell-shaped member 49aV and In order to accelerate the boosting effect pro this diaphragm which is preferably composed of duced by the gooseneck during flushing opera 10 rubber, leather, rubberized fabric, or the like, nor tions, particularly where low pressure water sup mally rests on both valve seats 38 and 39, thus ply conditions exist, the gooseneck is provided normally closing the annular space 3S. A disc 43 adjacent the lower end of its intermediate por of relatively thin resilient material bears against tion I4, with a lateral tubular extension 20 (see the outer face of the diaphragm 42 against which Figures l and 4) having an opening 2| normally . it is retained by, a centrally arranged tubular closed by a weighted gravity valve 22 which is rivet 44. That end of the tubular rivet 44 which I5, serves the same purpose in the gooseneck I2. l connected as by a link or chain 23 to an arm -24 is disposed withinthe bore of the tubular mem (see Fig. 1) that is carried by a manuallynactu ated shaft 6I) of the flush valve, to be hereinafter more fully described (see Fig. 4). Where ‘the tank is formed of porcelain, plastic or composition, the tank bottom below the open ber 32 serves as a ‘seat for a small disc valve 45 whichis carried by a valve stem 46, one end of 20 which is rigidly secured to a piston 48 reciprocally mounted within the cylinder 4I and the other` end of which extends loosely through the bore of the lower end of the gooseneck member I2 is in tubular rivet 44 so as to receive the disc valve creased in thickness to form a rib IIlb which ex 45 thereon in position to engage and elïectually tends upwardly along the inner surface of the 25 close the associated end ofthe tubular rivet 44 tank I0. Formed in the outer portion of this rib when the piston 48 moves to the right, as viewed adjacent the end wall, is a vertically disposed on Figure 3. This same stem 46 also carries an duct 25, and connected to the lower end is a water other disc valve 45a in position to engage the op supply pipe 26. If desired, this pipe 26 may be posite end of the tubular rivet 44 andeftectually provided with external flanges 26a and cemented 30 close it when the piston 48 returns to that posi in a recess in the bottom of the tankgas seen in tion in which it is «illustrated in Figure 3. As is Fig. 10. ’ ' best shown in Figure 11, a bleed opening 45h ' VAlso formed in the rib Iûb are parallel ducts is formed in each of the Valve discs 45 and 45a, ’ 21 and 29 the upper ends of which both open into thus providing for a ~ limited amount of flow a small chamber IIld adjacentv the upper end of 35 through the tubular rivet 44 regardless of which the'rib Iûb. rThe lower end of the duct 2'I com of the valve discs 45 or 45a is in engagement Iwith municates through an opening 28 with the inte the rivet 44. Consequently, the bore of the tubu rior' of the discharge tube II; and the lower end lar member 32 is always in communication with vof the .duct 29 communicates with a tube 30 which the interior of the bell-shaped housing member inclines upwardly into the inlet portion I3 of the 40 43a to the extent that equalization of pressures gooseneck I2.. ` ’ ' in both these chambers is assured. When the piston valve 48 moves tothe right from the position in which it is illustrated in Fig ' The length of the tube 39„i. e., the point at `Which its upper end is located, is determined by the pressure of the water supply in the main, a ure 3, it draws with it the stem 46, with the result lrelatively long tube 38 being employed when the that the valve disc 45 engagesv the associated end ‘of the tubular rivet 44~`and, upon Vcontinued-move ment to the right, withdraws the diaphragm 42 off both valve seats 38 and 39, and when the pis ton returns to theV Figure 3 position the' disc 45 available water supply is at low pressure and a shorter one for high pressures. ' Just below the upper‘edge of the tank' I0, the rib IIlb terminates in a suitably enlarged portion, orboss, IIJc upon which is mounted a float-actu ated ?lushing valve which is indicated at its en so engages the rivet 44 that the diaphragm 42 tirety at 48. This valve 4I) is mounted upon the kboss Iûc by’means of a tubular member 32 having Athreads 32a formed on its outer surface, these threads serving as'the means for rigidly mount ing the valve 40 in position. An aperture 33 in the> tubular member 32 registers with the upper `end of the water supply duct 25. A cylindrical ñange 34 of materially greater diameterV than the -tubularrmember 32 is supported thereon in axial 60 ‘alignment therewith by means of a radially ex tending ñange 34a; and upon the outer end of this cylindrical ñange 34, an annular flange 35 is supported, the inner face of this flange 35 being seated against the outer face of the boss I0c while the outer face of the annular ñange 35 is spaced outwardly froma valve seat 38 which is formed on the inner end of the tubular member 32, with the result that another annular valve seat 39 formed on the inner peripheral edge of the an nular flange 35 is in substantially planar align -`ment with the valve seat 38, thus providing an is returned into sealing engagement with both >annular valve seats 38 and 39. A packing 48a is provided inthe inner end‘of the piston 48 in position to eiîectually engage a valve seat 49 encircling the opening 4‘I through which the stem 46 extends into'thel cylinder 4I, thus providing positive. assurance against leak age into the cylinder 4I when the piston 48 isin its Figure 3 position. Preferably a pair of parallel arms 4Ia extend ing beyond the inner end of the cylinder 4I sup port a pintle pin 50 upon which a head 5I ispiv otally mounted. The axis 0f the pintle pin 50 is horizontal and preferably it is disposed slightly below the axis of the cylinder 4I and its _piston 48. Aligned conical recesses 52 and 53‘are formed in the inner face of the rocking head 5I and the outer face of the piston _4I respectively. The rounded ends of a pin 54 are seated »within lthe 70 two conical recesses 52 and 53, this pin preferably being Yretained in position, thus interconnecting the rocking head 5I and the piston 48-by’pivot annular opening Siìbetween the valve seats 38 pins 55. A . ~ ï ¿and 39, which opening leadsl into a substantially A rod 56 rigid with-the head 5I» extends'out annular chamber 3‘I encircling the inner end of 76 vvardly therefrom and carries a suitable ñ'oat`51 ‘2,412,691 5 at its _outer end, andprojecting upward from the rocking head 5| is a ñnger 58, the upper end of which is curvedtoward the valve 49 as indi cated at 59. ‘ i ' 6 with which water is expelled through the tube 39’upwardly into the inlet end; I3 of the goose~ neck I2. ‘ l » j HThe float 51 should be so positioned, by bending the rod 56, so that the maximum water levelwithin the tank Iû is approximately as indicated by the dotted lineas-#œ of Figure 2. When> the water level within the tank is at this position, the float 51, floating upon the surface of the water, maintains the valve 49 closed Iby forcing the piston d8 to its Figure 3 position, and, as hereinabove described, \ ‘ A shaftöû is journaled in suitably aligned bear ings 69a which are preferably formed upon the upper side of the cylinder III and a short arm EI rigidwith the shaft 50 extends radially there from. 4A notch or recess 52 is formed in the outer end of the arm 5I within which the rounded end 59 of the ñnger 58 is adapted to seat when the shaft i60 is rotated in counter-clockwise direction as viewed upon Figure 3 through a distance great enoughV to bring the recess 62 into registry with causing the diaphragm 42 to seat upon the valve ‘ seats 38 and`39, thereby preventing flow of water from the supply pipe 25 beyond that end of the 15 central tubularmember 32 of the valve 49 upon the rounded end 59. . Awhich the valve seat 38 is formed. Owing to the The shaft 69 extends through a bearing 39h in presence of the bleeder holes 451i in the disc valve aiwall of the tank I9 and the outer end of the 45a, su?lcient water under pressureis permitted shaft 6I carries a manually operable handle 53. to flow past the diaphragm so as to equalize The shaft 6| also carries a preferably adjustably mounted arm B4 carrying a counterweight 65a 20 pressures on both sides of the diaphragm and thereby avoid the‘tendency for the water under on its outer end, the parts being so proportioned pressure within the supply pipe 29 to unseat the and arranged that the counterweight 55a, urged diaphragm, However, since the diaphragm also by gravity, yieldably retains the shaft 9i] in that `seats upon the valve seat 39, which describes a circle of less diameter than the reinforcing disc position wherein the arm 6I is disposed with its _notch 62 out of registry with and below the en larged end 59 of the ñnger 53, i. e„ in its Figure flâ,'distortion of the diaphragm d2 by such fluid pressure acting on the opposite side of the dia phragm from that which bears against the valve 3 position. An opening 55 is provided in the lower portion seats is prevented. of the annular ilange 36 of the valve dii, this open To operate the hereinabove described appa ing 65 establishing communication between the 30 ratus, the handle 53 should be depressed, rotat annuluar chamber 31 and the chamberY I9d with ing the shaft 50 in a counter-clockwise direction which the upper ends of both ducts 21 and 29 as viewed in Figure 3. The relationship between communicate. An air inlet opening t1 is pro the arm 9|` on the shaft 69 and the ñnger 58 vided in the rib Iüb just below the boss Iíic, this with its curved end 59, carried by the rocking opening establishing communication between the interior of the tank I9 and the upper ends oi both ducts 21 and 29. The function of this open ing 31 is tobreak any vacuum that might developwithin the ducts 21 and 23 should the valve 4|) be opened at any time when the supply of water 40 under pressure` through `the _supply pipe 25 is interrupted. This avoids `all possibility of the development of syphonic conditions which other wise might tend to draw contaminated water from the flush tank I9 through the duct 29 or head 5|, is such that as the shaft is so rotated the arm 5I causes the finger 58 and head 5I to rotate in a clockwise direction as viewed upon Figure 3, throughout a distance sufficient to move the piston 43 to the right far enough to unseat the diaphragm ¿i2 from the seats 38 and 39. This movement of the head 5| also causes the float 51 to move downwards, submerging the float 51 within the water in the tank l0. Unseating the diaphragm 42 from the seat 38 permits water to flow from the supply pipe 29 through the tubular from the toilet iixture through the duet 21 back member 32 around the seat 33 and thence through through the valve ¿e and into the water supply the opening 3G to discharge through the cham system with which the supply pipe 26 communi~ ber Iild into both ducts 21 and 29. It should be cates, if; the supply of water in the pipe 2S is interrupted and a partial vacuum developed 50 explained that the relationship of the lupper ends of the ducts 21 and 29 to the chamber Iiid is therein. . l such that most of the water will «be carried from Preferably a bleeder duct 98 leads from the the chamber I9d through the duct 29 and only `inner end of the cylinder' ¿il downwardly to Aestablish communication with the chamber IIld so as to provide for disposing of any water that might otherwise collect within the cylinder 4I. Depending from the lower side of the rocking i head 5I is a lug 39 through which an adjusting a relatively small portion delivered by the duct i 21 directly to the discharge, or outlet tube II. The major portion of the water thus delivered through the valve 40 is forced upwards through the tube 39 and discharges from the upper end y thereof as well as through a series of jet open screw 1D is threaded. Another lug 1| formed on the under side of the cylinder 4| in alignment 60 ings 3| formed in the side of the tube 230 within the inlet member I3 of the gooseneck |2. The with the lug 59 has an opening 12 therethrough ‘ water delivered to the gooseneck I2 is ejected through which an extension 13 of the screw 19 `extends with a suliicient degree of looseness to - permit free sliding movement of the portion 13 with respect to the lug 1I. However, the extent of such movement is limitedby a coil spring 15 which is under compression between the lug 12 and a shoulder 1li formed on the screw 19. By adjustment of the screw 19 the degree of com pression of the spring 15 can be regulated, thereby making possible variation oi the distance through which the rocking head 5I can rotate in response to downward movement of the iioat 51. In this manner, the degree of opening of the valve 40 can be Vregulated so as to determine the velocity from the tube 30 at considerable velocity, flow ï ing upwards within the member I3 preferably on both sides of the partition I9 in such a manner 65 as to carry a considerable quantity of the water ñlling the member I3 to the level of the line :v4-œ over the bend of the gooseneck I2, defining the' juncture of the portions I3 and I4. The amount 70 of water constituting this quantity will be de termined by the adjustment of the screw 10 which limits the extent of opening of the Valve 4I), as hereinabove described, and should be so regulated as to cause development of the 75 syphonic conditions within the gooseneck I2` 2,412,691 i 8 7 Vwhich lwill cause the remainder of the `water ywithin the tank> I0 to be drawn through the opening I3a in the lower end of the inlet por tube having a plurality of jet-forming openings tion I3, through the gooseneck I2, and thence into posed partition within said gooseneck extending therein at diiîerent elevations _within said inlet end of said gooseneck, and a longitudinally dis the outlet tube I I.
