Description

May 8, 1962 J. P. MAGOS ET AL ACTUATING MECHANISM FOR PLUMBING FIXTURE 2 Sheets-$heet 1 Filed Feb. 6, 1959 y 8, 1962 J. P. MAGOS ET AL 3,032,778
ACTUATING MECHANISM FOR PLUMBING FIXTURE Filed Feb. 6, 1959 2 Sheets-Sheet 2 JZxP @W 1 United States This invention relates to a combined water closet or bowl and mechanism therefor. More specifically, it is concerned with the type of closet construction in which preferably the water supply tank therefor is located behind the wall of the bathroom and is actuated by means of a handle and lever arrangement mounted either upon the closet bowl proper or adjacent thereto. In most cases, the water closet is the kind termed by the trade as the wall.- hung type and therefore makes it desirable to provide for the flushing tank being behind the wall and positioned at such predetermined height to provide the desired flushing'of the closed bowl or urinal.
To accomplish the benefits of this type of operating mechanism, a more positive and direct operating mechanism than heretofore used is employed.
Therefore, one of the principal objects of the invention is to provide a closet flushing construction in which a substantial part of the actuating mechanism is capable of being located behind the wall between studding and is of a sturdy and durable character. It is one in which its installation is comparatively easy to make and is virtually trouble-free thereafter because of the positive. linkage employed relative to the tank. H
Another object is to provide for a closet bowl flushing mechanism in which theflush actuating mechanism employed returns to its normal position without requiring special resetting. v
A further object is to provide for an actuating mechanism in which the mounting thereof relative to the flushing tank is resilient, is free from objectionable noise and vibration and is easily maintained in a desirable operating condition throughout substantially its life.
Other objects and advantages will become more readily apparent upon proceeding with the specification read in light of the accompanying drawings, in which:
FIG. 1 is a reduced fragmentary sectional view of a wall mounting showing one preferred application of our invention;
FIG. 2 is a magnified view of the lever mechanism employed;
FIG. 3 is a front reduced view of a wall-mounted bowl assembly embodying our invention; and
FIG. 4 is a magnified fragmentary sectional view of a portion of the actuating mechanism in relation to the closet bowl.
Similar reference numerals refer to similar parts throughout the several views.
Referring now to FIG. 1, a wall-mounted water closet or bowl generally designated 1 is shown mounted upon the wall W of a bathroom or the like by the usual means, such as bolts (not shown), applied to the holes 2 and 3. The closet tank, generally designated 4, is preferably elongated and of substantial depth to provide suflicient capacity for proper flushing of the bowl and is suitably mounted between the usual studs or up-rights (not shown) supporting the wall from the rear. The closet tank has the usual discharge outlet including a flapper valve 5 for effecting predetermined water discharge therefrom, having a construction for example of the type shown in Crane Co. flapper flush valve Patent No. 2,756,437, granted July 31, 1956. As indicated, the flapper valve 5 is actuated by a chain or suitable linkage 6 attached thereto. The chain is attached at its upper limit to a transverse arm 7 atet 3,032,778 Patented May 8, 1962 forming an angular portion of the substantially vertically extending actuating link rod generally designated 8. The latter rod at its lower end portion may be suitably offset as indicated at 9 to permit adjustability in lever mounting relative to the studding and also allowance for desired leverage with respect to the pivotally mounted lever 11. The rod 8 is fixedly attached to the said pivotally mounted lever 11 by means of the clamp 12 and the set screw 13 threadably bearing against the rod 8 to connect the offset portion 9 of the rod 8 with the horizontally disposed lever 11. The latter lever, as more clearly shown in the plan section of FIG. 4, is journalled on an angular portion 14 thereof within the bowl housing 10 and is received within the threaded shouldered bushing 15 bearing against the interposed washer 16 mounted over the bowl aperture 17. A threaded retaining nut 18 within thebowl housing 10 holds the bushing 15 firmly in position within the bowl aperture 17. At its outer end, the angular lever portion 14 of the rod lever 11 is provided with a knurled end portion 19 over which the actuatmg handle 21 is frictionally held in place. The said handle has the elongated lever portion 22 for such actuation. Mounting the flushing handle 21 on the side of the bowl eliminates the need for a special wall opening.
It will be clear that upon depressing the lever portion 22 of the handle 21, the pivotally movable lever 11 will be actuated and the rod 8 will thereupon be moved axially upwardly and thus causing the chain 6 to be moved similarly, thereby lifting or peeling ofi the flexible flapper valve 5 from its tank seat 23. This activation or me flapper valve permits the water contained within the tank 4 (supplied thereto by inlet means not shown) to discharge into the downwardly extending pipe 24, thence into the elbow portion 25, and into the inlet bowl passage 26 more clearly shown in FIG. 4 for the bowl flushing function. v
In providing for the quiet return of the lever to its original position without objectionable noise and vibration impact, a spring 27 is employed, being clamped between the fixed washer or shoulder 28 at its upper limit and being supported at its lower end portion upon the tank angularly formed apertured bracket 29 to receive the upper portion of the rod 8. The said spring also maintains the pivotally movable lever 11 in the normally horizontally disposed position illustrated. The bracket member 29 is attached to the upper wall portion of the tank 4 by means of a bolt and nut assembly 31.
Under most conditions of installation, it is desirable to provide the wall W with a suitably large apertured portion 32 within which the lever 11 is moved pivotally from its bearing portion 14 in the threaded bushing 15 under the actuation of the handle 21 as previously described.
While a wall-mounted bowl installation is illustrated and described, it will of course be appreciated that a floor-mounted closet bowl may be used if desired, without adversely affecting the advantages flowing from the use of the operating mechanism and its comparatively widespread adaptation. It will thus be apparent that the actuating mechanism and the novel manner of its installation is capable of being employed with a wide variety and number of flushing devices wherein the operation of a flushing tank concealed behind a wall may be conveniently accomplished.
Therefore, it is the desire to be limited insofar as the broadness of the invention is concerned to the claims as hereinafter appended interpreted in light of the art.
We claim:
