It is particularly aimed to provide an improved structure using two inverted U-shape traps or chambers vented with two breather tubes. and one 15 upright U-shape trapl or chamber constructed and arranged without moving parts to act as a valve to control the flow of water from the flush tank to the toilet bowl. l It is further aimed to provide in connection with 20 the novel trigger arrangement and ball cock struc ture constituting the subject matter of said appli cation 112,806, novel adjustment screws on the ball cock and breather tubes on the flushing unit to synchronize the action of the ball cock and 25 flushing unit so as to properly control the flow of Water into the flush tank and out of the flush tional water closet -flush tank in the bottom wall of which a'water supply pipe I I is connected, ris- y 1 ing to a suitable height and mounting a bracket '350 I2 having a depending outlet or hush pipe i3, terminating above the bottom wall of the tank I0. The supply of Water through the pipe ll is normally cut-off at a conventional Valve It under control of a vertically slidable plunger l5, suit ably mounted in the bracket I2 and engaged by an adjustable screw I6 carried by a lever-il and pivoted as at I8 to an arm I9 of the said bracket I2. . . , Said bracket I2 also has another arm at 22 to A2l) which is pivoted at 2 I‘, a lever 22 from which an arm 23 extends and carries a float or ball 2li at its free end. The lever or trigger 22 carries an adjustable set screw 25 for co-action with the free end of the lever I'I. An operating ring 2S 25 is pivoted at 2'I to the trigger lever 22 and to such ring links 28 are pivoted at 29 and such links by means of a screw or the like 32, are pivotally and slidably connected to the lever I'l through an tank through the flushing unit to the toilet bowl, and to provide such a construction having the ad vantages set forth, which »may be incorporated . 30 30 within the flushing tank, and which may be elongated slot 3| of the lever Il.

The inlet to the trap device at 34 is above the bottom wall of the tank-and a tor tuous passageway is provided through the trap '« device providing a trap as at 35, an inverted trap as at 36, and an air chamber 3l'. kA refill tube 38 is connected to the trap device, extending upwardly therefrom, thence down wardly, and thence upwardly terminating within the lower end oi the pipe I3.4 Also connected to the trap device and communicating with the air chamber 31 is a breather pipe 39. Adjacent the breather pipe 39 is a second breather pipe et, í. extending above and thence downwardly and be- '3 ing connected to the trap device in communica tion with the inverted trap or chamber 3B. It will be noted that the inlet or lower end of the breather pipe 39 is slightly above the inlet or 55 2 2,120,856 lower end of the breather pipe 40 and the latter is slightly above the lowest water level. In the description oi the operation of the de vic‘e, three water levels will be referred to as have been indicated in Figure 1 of the drawings, name~ ly high water level, normal water level, and low est water level. The trigger ring 26 is actuated Y10 1. A device of the class described having a flush tank, a water supply pipe rising therein, said pipe having a downwardly extending discharge pipe, float control means, a valve controlled by the later to govern the supply of water through the ñrst mentioned pipe, a trap device within the tank having a flush pipe leading therefrom, said by a push button or lever arrangement or other~ trap device having an inlet below the water level wise from without the tank which raises the same, and a passageway therefrom to the flush pipe of breaking the lock between the ring 26 and links 28, which releases the pressure on the lever I‘I, connected portions of U-shape one above the other, a reñll pipe extending from adjacent the allowing the water to enter the tank IIJ through the pipe I3. This causes the water to rise in the tank I0 from the normal water level ,to the lower end of the discharge pipe to the upper por tion of the interior of the trap device, said reñll 15 high water level, at which point it displaces the air in chamber 36, which fills with water through pipe adjacent said lower end of the discharge pipe being upturned and engaging in the discharge 15 pipe, a breather pipe communicating with the in the inverted U-trap 31. The water then sets upY Y terior of the trap device at the upper portion, and siphonic action through the U-trap 35 over the a breather pipe communicating with the interior inverted U-trap 36, the water travelling thence of the trap device at the upper portion ofthe 20 down through the regular flush pipe 33 into the other U-shape passage therein. toilet bowl. As the water level lowers in tank iii, 2. A device of the class described having a ñush the ñoat ball 24 drops with the water level caus tank, a water supply pipe rising therein, said pipe ing the ring trigger plate 2 6 and connecting links having a downwardly extending discharge pipe, 28 to automatically fall into locking position. iloat control means, a valve controlled by the lat 25 When thewater level fallsy below the lower end ter to govern the supply of water through the iirst of breather pipe 39, the upper end of which opens into the chamber or trap 3l, air enters pipe 39 and ñlls chamber 36. A short interval later, the water falls below the open end of the breather 30 pipe 40 which extends above the high water level, and air enters chamber 39. An inverted U-trap is formed returning down and opening into the trap or chamber 3G which breaks the siphonage pull at this point and leaves U-trap 35 filled with 35 water which seals chamber` 36 and causes an air pressure to build up therein as the water level rises in the inlet 34 of the trap device and in the tank I 0 to a predetermined normal water level which is regulated by the adjustment screw I 6. 40 The adjustment screw 25 presses down on the lever Il and regulates the interval of time which float ball 24 remains at the lowest position, which allows chambers 2ï and 2S to become filled with air before the rising water level seals chamber 45 36 by rising aboveV the lower ends of breather pipes 39 and 40. Refill pipe 38 extends below the lowest water level and above the highest water level, forming a U-trap at the lowest point. Water entering the flushing unit through the re 50 ñll pipe 38 flows into U-trap 35, causing the water level therein to rise, overñowing through the sec ond inverted U-trap 3B and thence through the flush pipe 33 to reñll the toilet bowl. It will be noted that the ,adjusting screw I6 55 slows down the ball cock 24 at the lowest water level, such hesitation allowing the air chambers to reñll with air. The air tubes or vents 39 and 40 are breaker vents and also silencers as they do not make a hissing noise. The slotted connec 60 tion at Sli-3| and screw I6 co-act as they allow the feed of the incoming water to be slowed down, say for a few seconds, to allow the air cham bers to refill with air. Y It will be noted that the plunger I5 is loose and 65 not connected to the ball cock valve at I4. The water pressure opens the ball cock valve when the lever I'I with the screw I6 disengages it. Back siphonage will close it shut and tight. . Various changes maybe resorted to provided 70 they fall within the spirit and scope of the in vention. I claim as my invention: mentioned pipe, a trap device within the tank 2.5 having a ñush pipe leading therefrom, said trap device having an inlet below the water level and a passageway therefrom to the flush pipe oí con nected portions of U~shape one above the other, a reñll pipe extending from adjacent the lower end of the discharge pipe to the upper portion of the interior of the trap device, said reñll pipe adjacent said lower end of the discharge pipe being upturned and engaging in the discharge ' pipe, a breather pipe communicating with the interior of the trap device at the upper portion, and a breather pipe communicating with the interior of the trap device at the upper portion of the other U-shape passage therein, the second 40 mentioned breather pipe having its lower end be low the lower end of the other breather pipe, said second mentioned breather pipe being U-shaped and extending above the high water level. 3.
