Definitions

  • FIG. 1 32 /2 ll In! I4 I ll ⁇ J 22 PORT CLOSED POSITION 26 FIG. 1
  • FIG. j 1 26 5 INVENTOR l6 JOHN J. BARNUM J. J. BARNUM 3,529,773
  • a transfer valve for a washing machine including a tubular valve body 12 with a tubular valve member 34 telescopically slidable therein between a port closed position (FIG. 1) in which water flows through the valve member 34 to a conduit system of a dolly supported above the transfer valve.
  • a port closed position FIG. 1
  • water is diverted to a sprayhead 24 rotatably mounted on the valve body 12.
  • My invention is an improved transfer valve inculding means responsive to a portion of a slide-in dolly, permitting selective use of the rotatable sprayhead 24 or valve member 34 without the necessity of interchanging them.
  • This invention contemplates alternate selectivity which is automatically responsive to the dolly being received internally of the washing machine in its proper position.
  • FIG. 1 is a partial cross sectional view of one embodiment of my invention, with parts broken away;
  • FIG. 2 is the same as FIG.1 with the exception that the parts are shown in a second relative position and more of the parts removed.
  • a water fluid inlet 10 only the top portion of which is illustrated. It will be understood that this is rigidly mounted in the bottom of a washing machine and communicates with a source of water.
  • Inlet 10 terminates at its upper end in a smaller outside diameter, vertically extending tubular inlet conduit or valve body 12, forming a shoulder with the lower portion of the inlet 10.
  • I provide an annular collar 14 resting on the shoulder of inlet 10 pinned to the upper tubular valve body 12.
  • the pin 16 passes through two coaxial bores in the sidewall of the valve body 12.
  • I provide a flanged belt or stop member 18, rigidly threaded at 20 through the pin 16.
  • a pair of relatively large coaxial outlet ports 22 in the sidewall of the tubular valve body 12 which provides communication between the valve body 12 and a sprayhead 24 rotatably embracing the outside circumference of the tubular valve body 12, as for example, by a pair of annular seals 26 seated in internal annular shoulders formed in the upper and lower ends of a tubular shank portion 28 of the sprayhead 24.
  • a pair of horizontally extending sprayhead branch conduits 30 having a plurality of perforations 32 in the upper surface thereof, which perforations are preferably provided at such an angle to the vertical axis that the water being expelled therefrom causes the sprayhead 24 to rotate.
  • valve member 34 Internally of the tubular valve body 12, I provide a tubular valve or valve member 34 telescopically slidable therein. Sealing means are provided between the external sidewall of the valve member 34 and the internal sidewall of the valve body 12 by a plurality of O-ring seals 36, seated in angular grooves in the external sidewall of the valve member 34. Valve member 34 terminates at its lower end in an internally disposed annular flange 38 defining a port 40 larger in diameter than the shank of the flanged bolt 18 and smaller in diameter than the head 42 of the bolt 18. In this manner, the head 42 of the bolt 18 serves as a closure for the valve member port 40 when in the uppermost postion illustrated in FIG.
  • valve member 34 when there is no water pressure internally of the inlet 10 and tubular valve body 12, the valve member 34 drops by gravity to its lowermost position (not shown) in which the internal flange 38 of the valve member 34 engages the pin 16 which is the inactive lowermost position of the valve member 34.
  • FIG. 1 illustrate only a fragmentary portion of a lower surface or bottom 46 of a dolly or other slidable frame carrying accessories (not shown in detail) corresponding to the dolly of the Francis S. Faust application Ser. No. 608,702.
  • the seal 48 has an inlet port 52 which receives water or fluid pressure as indicated by the arrows 44 which is then delivered through a conduit system in the dolly (not shown) to spindles carried by the dolly (not shown).
  • the spindles support glassware or other items to be washed in the washing machine in a manner well-known in the art and described in detail in the heretofore mentioned Faust application.
  • Water passing through the valve body 12 applies sufi icient force to the lower surface of the valve member internal flange 38 thereby to elevate the valve member 34 to the FIG. 1 position in which the outlet port defined by the open end at the upper end of the valve member 34 is brought into sealing relationship with the resilient seal 48. In this position, the fluid circuit is completed to the outlet orifices of the dolly spindles (not shown).
  • said selective means includes, a port in said valve body communicating with said sprayhead, a port in said valve member communicating internally of said valve member with said outlet port and stop means for selectively limiting movement of said valve member between a port closed position in which said valve member closes said valve body port and opens said valve member port and a port open position in which said valve member opens said valve body port.
  • valve body and valve member are tubular and telescope with each other.
  • a claim in accordance with claim 2 including;
  • a claim in accordance with claim 2 including means for closing said valve member port when said valve member is in said port open position.
  • valve member is slidably mounted inside said valve body and the valve member has an inlet port at that end of the valve member which is adapted to close said valve body port.
  • valve member outlet port is at an end thereof opposite an end thereof which closes said valve body port.
  • valve member also has an inlet port at that end of the valve member which is adapted to close said valve body port.
  • a claim in accordance with claim 9 including a stop means movably mounted with said valve body and valve member for stopping said valve member in the port closed position, said stop means having a port therein communicating with said valve member outlet port.
  • a claim in accordance with claim 10 including an other stop means for stopping said member in said port open position when said first mentioned stop means is removed from its valve member stopping position.
  • the apparatus according to claim 13 including means for rotatably mounting said sprayhead on said valve body and means causing said sprayhead to rotate when water is expelled from said sprayhead.
  • valve body includes an outlet port in fluid communication with said sprayhead and wherein said coactive means includes means for opening said valve member outlet port and closing said valve body outlet port and for alternative- 1y closing said valve member outlet port and opening said valve body outlet port.
