Definitions

  • 'lhis'invention relates to flush valves and has for itsfprincipal' object the provision of a simple .and Aeconomical devicefror automatic-ally delivering 'a predetermined volume of fluid toda reservoir such as the basin' of Water closet .or the like.
  • rOne particular feature of the invention resides in the provision of yan adjustable hydraulic governor, or dashpot, adapted to retard the clos'ingmovement of an outletV valve-so that a 'measured 'quamV tity of fluid will" pass lthrough the outlet after the mechanism for opening the valve Vis released.
  • Fig. .1 is a central vertical Vsection of the improved valve
  • Fig. 2 is a section on the line 2-2-Yof F i951;
  • Fig. 3 is a transverse*section ou the line 3 3 of Fig. 1; y
  • Fig.. L is a central vertical section of the device taken at right anglesto that of Fig. .l g
  • Fig.k 5 is an inside end view of the dashf pot adjuster.
  • Fig. 6 is a transverse section on line 6 6 of Fig. l.
  • The'structure includes a substantially c vlindrical casing 9 havingan outlet port 13 in its bottom, a removable cover 11 having an inlet port 10 in one side, and a poppet valve 14 seating in the port 13.
  • a carriage or frame for the valve comprising top and bottom cross-heads v15 and 16, respectively, vand diametrically disposed spacerro-ds 17, is mounted for sliding movement longitudinally ofthe casing in a guide plate 18 fixed Within thebore of the casing.
  • the valve 14 is provided on its upper face with a groove loosely to receive the cross head 16 Which is attached by a pin 19 hav,- ing a loose fit with an opening in the crosshead and a tight fit with aligned openings FLUSH VALVEy Y f f 19.29. ⁇ serial No. 356,947. 'n
  • valig'e is .thus Msecurely butfloosely4 mounted uponv the lifting ⁇ car-V riagefsothat a ,tight 'seating ofthe valve is insured.
  • hydraulicy governor is-provided to retard theseatlngpmovementof the valve, once thelatterfhasfbeen opened'.
  • This governor preferably comprises a dash-pot disposedin pistonto prevent binding and to permit the Y slow escape lof Wateras lthe piston moves downwardly.
  • the ⁇ preferred construction lof theadjfust'ing means comprises a sleeve 20 having ribs 21 punched inwardlyto slidel Vin corresponding grooves in thestem 28 so that rotation-of the sleeve from outside the casing lcauses kthe stem to thread upwardly ordovvnvvardly in the cross-head 15.

  • They mechanism 4.for lifting the valve carriage ⁇ to opent-.heball valve preferably comj prises a handle '33 and ⁇ a rotatable shaft '34 mounted in a nipple 35 screwed' into the side Wall-of 'the casing, the shaft having a ⁇ cam 36 at .-itsinner end bearingl againstv the under side of a member carried by the carriage, such as the flange 37 of the cross-head 15.
  • a stuffing box 38 may be threaded upon the inwardly projecting end of the nipple 35 to prevent leakage of water around the shaft.
  • the handle is connectedl to the shaft by a pin 39 extending through slots 40 in the tubuar part 4l of nipple 35 which permit limited rotation of the handle to open and close the valve.
  • the handle is automatically restored to normal position by coil spring y42.
  • the nut 43 which closes the end of tube All may be provided'with a rubber buinpei' all for a 'toilet' seat cover.
  • the operation of the device is "extremely simple.
  • the valve is normally closed by pressure of the Water and the handle is held in the inoperative position shown in the figures by the spring 42. Movement of the handle then rotates the shaft 34: and Vthe cam 36 lifts ⁇ the lcarriage and opens the valve until the cross-head 16engages ⁇ the 'lined platel. As the valve lifts water flows into the cylinder past check valve 27, as Well as ⁇ between the piston and cylinder, thereby permitting the valve to be opened quickly. As soon as the handle isI released the valve automatically closes.
  • a valve constructed in accordance with the ⁇ foregoing description is economical to manufacture, easy to assemble and disassem ble, and simple to'operate'ythe structure is compact and may be so fashioned as to be attractive in appearance without sacrilice of operative ellicieiicy y rand the movable elements aresoconstructed and arrangedthat the Operation of thevalve is extremelygquiet and that Vthe possibility of Afaulty operation isy remote. It will be understood, however7V that details of construction may be varied for particular purposes without departing from the essence oi' this invention as delined in the following claims.
  • a lusli valve comprising a casing having'a valve seat at one end, a' 'guide in the 'casing:intermediate its ends, a'cylinder on the guide having an open end facing away from the valvef'seat, a carriage having rods sliding in the guide, ⁇ and cross-heads interconnecting the rods on opposite sidesfotthe guide,"a piston mounted on one cross-head to cooperate withJsaid cylinder and a valve on the other cross-headto cooperate Withsaid seat, a threaded stem for adjusting theipiston longitudinally of the cylinder, and a sleeve journaledin the Otheiiend of' the casing-for rotating the threaded stein from outside the casing, said sleeve Shaving sliding but other cross-head to cooperate with said seat, Aand means. interconnecting the valve with trie other cross-head to permit universal movement of the valve relatively to its seat,
  • said means comprising a pin in aligned openings in the valve and cross-head, the openings in one part being larger than the pin and one part having an elongate recess extending transversely of the'pin loosely to receive the other part.
