Definitions

  • the invention is directed to plumbing fixtures such as water closets having a direct connected flush valve for flushing the water closet and a control valve connected to the flush valve for controlling the inlet water supply.
  • the flush valve is connected to the control valve by a fitting or nipple which is threaded into the inlet side of the flush valve and connected to the control valve by a ground joint connection and a coupling nut.
  • a further object is to provide a new and improved fitting which can be readily adjusted to provide for varia tions in center-line dimensions between a flush valve and 3,273,919 Patented Sept. 20, 1966 control valve up to at least inch from the standard 4% inch dimension.
  • Another object is to provide a novel fitting between a flush valve and its control valve which will be leakproof regardless of how often an adjustment may be made.
  • Another object is to provide an adjustable coupling between a fitting and valve in which the connection can be repeatedly made without leakage occurring and which will not come apart under high pressures or when subjected to inadvertent twisting action between them.
  • FIGURE 1 is an elevation of a typical flush valve installation with the invention incorporated therein;
  • FIGURE 2 is an enlarged cross-section of a portion of the novel fitting; while FIGURE 3 is an enlarged cross-sectional view of a modified form of the invention.
  • FIGURE 1 there is illustrated a well-known Sloan Royal flush valve 5 provided with the usual operating handle 6 and the threaded inlet connection 7.
  • the outlet flush tube 8 extending downward from the flush valve 5 is connected thereto by coupling nut 9 and leads into a plumbing fixture such as a water closet or urinal (not shown), to which it is connected by the usual slip-joint connection.
  • the inlet water supply pipe 10 projects through the wall surface and is threaded into the rear of the control or throttle valve 11.
  • the adjusting screw 12 in the control valve 11 enables the water supply to the flush valve 5 to be either shut off, or to throttle the flow to the proper rate to suit the plumbing fixture.
  • a fitting or nipple 15 connects the flush valve 5 with the control valve 11.
  • the flush valve 5 is always shipped with the fitting 15 threaded at 14 and already screwed tightly into the valve body inlet "7.
  • the fitting is provided with ribs such as 16 formed on the inside, as seen in FIGURE 2, for the purpose of accommodating a tool or key which is inserted into the fitting to enable the same to be tightly screwed at 14 into the inlet connection 7.
  • the coupling nut 17 is merely tightened up to the control valve 11 to complete the installation.
  • the present invention makes it possible to compensate for variations in the standard pipe roughing-in up to at least inch, of which /2 inch would be to the right of the center-line 18 of the control valve 111, and 4 inch to the left of the center-line 18. This variation is considered ample since most errors are made in the direction to' the right side of center-line 18.
  • the compensating adjustment is automatically accomplished in a simple manner by the present invention, the fitting 15 being merely inserted in the outlet 20 of the control stop 11 and the coupling nut 17 tightened up on the same to complete the connection.
  • the end of the fitting 15, opposite its threaded end 14, has a flanged recess 21, with flanges 21a, formed around it to accommodate an O-ring 22.
  • the O-ring 22 is slidable and compressed within the outlet 20 of the control valve 11 and provides a positive leakproof seal between the fitting 15 and the control valve 11.
  • a stop 23 is formed in the control valve body 11 to prevent the fitting 15 from being pushed too far into the body and interfering with the valve action.
  • a locking or gripping ring 25 Surrounding the fitting 15 and frictionally engaging the same is a locking or gripping ring 25 which is split at 30 to provide a spring action so it can be initially slid along the outside of fitting 15.
  • the gripping ring 25 is square-shaped in cross-section and preferably made of corrosion resistant steel, while the fitting 15 and valves and 11 are usually made of brass.
  • the gripping ring 25 and coupling nut 17 are both placed on the fitting 15 at the time the fitting is screwed into the inlet 7 of the flush valve body 5, so that the connection to the control valve 11 can be quickly made and the parts are not likely to be misplaced during shipment.
  • the locking ring 25 and coupling nut 17 are prevented from being removed and from the fitting 15 by the flange 21a forming the recess for the O-ring 22.
  • the gripping ring 25 is arranged so that one of its sharp edges 26 is normally in slidable and frictional contact with the outer surface of the fitting 15 as shown. Initially this sharp edge 26 does not bite or cut into the surface of the fitting but grips the surface only slightly so that it can be easily slid along the outside of the fitting due to the inward spring action of the gripping ring.
  • the end of the valve outlet bore 20 is formed with an inclined annular surface 27 which is of the same angle as one of the sides of the gripping ring 25 so that the two surfaces are in slidable mating relationship.
  • a similar inclined annular surface 28 is formed on the inside of the coupling nut 17 and abuts the gripping ring on the other side from the inclined surface 27 so that the gripping ring 25 in the final assembly, as shown in FIGURE 2, is clamped between the two inclined surfaces 27 and 28 and locked in place.
  • an installing plumber first roughs-in the water supply pipe as close as possible to the standard 4% inch distance from the flush valve center line 19 and then screws the throttle valve 11 on the pipe 10. Since the fitting is already factory screwed in and attached to the flush valve inlet connection 7, and the coupling nut 17 and gripping ring 25 are loose upon the fitting 15, the plumber merely inserts the end of the fitting 15 into the valve body outlet of the control stop 11. The fitting 15 slides into the outlet 20 a distance depending upon how far the plumber was at variance with the correct roughing-in. This distance could be up to /2 inch to the right hand side and at least 4 inch in the left hand direction. The coupling nut 17 is then slid along the fitting 15 carrying along the gripping ring until the coupling nut engages the threads 29 of the outlet 20 whereupon the nut is tightened to lock up and complete the connection.
  • the gripping ring 25 is clamped between the inclined surface 27 on the end of the outlet 20, and 28 on the inner edge of the coupling nut.
  • the inclined surfaces impart a horizontal thrust against the opposite inclined surfaces of the gripping ring 25
  • an inward and circumferential force is imparted to the gripping ring 25 which is effective to bite or cut its hard sharp edge 26 into the outer circumference of the fitting 15 as shown in FIGURE 2. It is held locked in this position as long as the coupling nut 17 remains tightly threaded on the end of the outlet 20 of the control valve.
  • the gripping ring 25 gouges into the metal of the fitting 15 and is held there by the coupling nut 17, a solid connection is established which cannot be pulled apart or become disengaged on relatively high pressures. The connection can be repeatedly made and disconnected without losing its effectiveness. Moreover the O-ring 22 being under compression establishes a tight leakproof static seal between the fitting 15 and outlet 20 which is effective in any relative position in which these two parts may be coupled together.
  • the gripping ring 25 is also somewhat effective as a seal by itself because as the coupling nut 17 is tightened and bites the sharp edge 26 into the fitting 15, the ends of the gap 30 in the gripping ring 25 are brought closer together.
  • the /1 inch range of adjustment is limited at one end by the extent to which the end of the fitting 15 can be inserted into the outlet 20 where it engages the stop 23, and at the outer end when the O-ring 22 will be adjacent the gripping ring 25 and still hold the connection firm and leak-proof.
  • the connection when finally established, cannot be blown apart in case excessively high water pressures are encountered or the coupling nut 17 is not properly tightened. Should high pressures cause the fitting 15 to be forced outward against the biting action of locking ring 25, the flange 21a around the O-ring recess 21 will contact the locking ring 25 to stop further outward movement and effectively prevent rupture or severance of the connection.
  • the gripping ring 26 unlocks and springs out of the groove it had cut in the fitting 15, and then can be easily slid along the fitting to a new position if desired.
  • the groove which has been gouged in the fitting is of no further concern in the assembly when another connection is to be made.
  • FIG. 3 a section of the fitting 15 is shown inserted into the valve outlet 20 and the couping nut 17 is threaded at 29 onto the outlet.
  • the split locking or gripping ring 31 is oblong in cross-section and its lower sharp edge 32 is engaged by the coupling nut 17 while an upper side portion 33 is contacted by the outer edge of the outlet 20. Tightening the coupling nut 17 on threads 29 provides a twisting movement to the gripping ring 31 causing its upper edge 34 to bite into the outer surface of the fitting 15 as shown. This provides an effective lock or grip for holding the fitting 15 in place in the outlet 20 so that it cannot be pulled out or disturbed when once installed.
  • flush valve and control valve is therefore only for the purpose of illustration and not limitation.
  • an adjustable connection for use between a flush valve and a control valve to compen: sate for variations in the relative position of the valves, said connection comprising a tubular fitting threaded at one end into the flush valve and having its other end slidably and adjustably inserted in the outlet end of said control valve to a position depending upon the relat1ve distance between the valves, the adjacent walls of said tubular fitting and said control valve being slightly spaced apart, the end of said fitting having spaced apart flanges formed thereon extending outward from the side of said fitting into close proximity to the walls of said control valve, an O-ring recessed in said fitting between said flanges and in slidable leak-proof contact with the walls of said control valve, a locking ring around said fitting slidable thereon and closely embracing the same and bridging the space between said fitting and said control valve, said locking ring having a sharp edge in slidable contact with said fitting, a coupling nut threaded upon the outside of said control valve outlet
  • a plumbing fitting for connecting the combination of a flush valve inlet with a control valve outlet, one end of said fitting being threaded tightly into said flush valve inlet, the other end of said fitting having an annular recess bordered by oppositely disposed flanges extending outward beyond the outer surface of said fitting, an O-ring in said annular recess in slidable leak-proof engagement with the inner circumference of said control valve outlet, a coupling nut in threaded engagement with the outer circumference of said control valve outlet, said coupling nut having a clamping edge portion closely slidable along the outside of said fitting, a split locking ring having a square-shaped cross-section and having a sharp annular edge contacting the outer circumference of said fitting, said locking ring being arranged between said coupling nut and the end of said control valve outlet, said coupling nut adapted to slide and force said locking ring along the outside of said fitting into engagement with the end of said control valve outlet, said locking ring having opposite disposed angular surfaces engaged
