FLUSH VALVE MECHANI SM Original Filed Jan. 28, 1952 John L. 07m #26 Patented Nov. 27, 1934 PATENT OFFICE j 1,982,550 FLUSH VALVE MECHANISM John L Shuttle, Mason City, Iowa Application January 28, 1932, Serial No. 589,498
Renewed April 19, 1934 1 2 Claims.
This invention relates to certain new and useful improvements in flush valve mechanisms.
The" primary object of the invention is to provide a flush valve mechanism associated with the flush tank of a water closet wherein the valve mechanism embodies a valve device controlled in its operation by a float and it is to be understood that the valve mechanism may be used wherever desired for controlling the supply of water to a receptacle, tank or similar means.
Another object of the invention is to provide valve mechanism especially designed for the flush tanks of water closets wherein a floating valve within a valve casing is closable upon a seat in the valve casing by means of a float arm engageable with a part of the valve casing in the manner of a fulcrum with the floating valve and float arm removable as a unit from the valve casing for repair or the like. With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.
In the drawing:-
Figure 1 is a side elevational view, partly broken away and shown in section of a flush tank for water closets having the flush valve mechanism embodied therein;
Figure 2 is a top plan view of the flush valve mechanism removed from the tank;
Figure 3 is an enlarged side elevational view of the flush valve mechanism with the float arm broken away; Figure 4 is another side elevational view of the flush valve mechanism with the float arm illustrated in section and extending through a side slot in the valve casing;
Figure 5 is a vertical cross-sectional view taken on line 5-5 of Figure 4, showing the dome upon the valve casing for directing the water issuing therefrom in a downward direction and with the float arm for operating the valve having fulcrum engagement with a part of the valve casing; and
Figure 6 is a horizontal sectional View taken on line 66 of Figure 5.
Te valve mechanism is illustrated in Figure 1 as associated with a flush tank 10 for a water closet that has a water supply pipe 11 entering the bottom wall thereof with a water-tight connection between the supply pipe and tank afforded by the nut and washer devices 12.
The valve casing of the valve mechanism com- 55 prisesa polygonal body portion 13 to facilitate mounting thereof upon the upper end of the water: supply pipe 11, the valve casing 13 being open at its lower end and internally threaded as at 14 for threaded engagement with the upper end of the water supply pipe while the upper end of the valve casing is of cylindrical formation and externally threaded as at 15. An annular valve seat 16 is carried by the inner face of the valve casing 13 with the operative face thereof spaced from the inner walls of the valve casing illus- 65,; trated in Figure'5 while outlets for the valve casing include radial ports 17 disposed annularly in the horizontal plane of the valve seat 16 as shown.
The valve mechanism further includes a plug valve 18, preferably of polygonal formation in 1 cross-section as shown in Figure 6 that is freely mounted within the upper cylindrical end of the valve casing 13 with a socket in its lower end for the reception of a renewable valve face 19. The upper end of the valve 18 isforked or bifurcated j for the reception of one end of a float arm 20 pivotally mounted therein as at 21, the float arm 20 extending through a longitudinally extending slot 22 provided in the upper cylindrical externally threaded portion 15 of the valve casing. A cap nut 23 is threaded upon the upper end of the valve casing 13 and is preferably of polygonal formation defining side facets 24 with a notch 25 provided in the lower edge of each facet as illustrated, the cap nut being mounted upon the valve casing in a manner to cause one of the notches 25 to register with the valve casing slot 22 so that the arm 20 may move into a notch 25 for fulcrum engagement with a side facet 24 of the cap nut to eifect pivotal movement of the float ,1 arm 20 for closing the valve 18 upon its seat 16.
The outer end of the float arm 20 is provided with an internally threaded eyelet 26 for the reception of a perpendicular pin 27 for the support of a 1 float 28, retained in position on the pin by the thumb nut 29 as shown in Figure 1.
A domeorhood member 30 has a threaded opening 31 in the head thereof that has threaded engagement with the externally threaded portion 15 of the upper end of the valve casing 13 and 100, is moved downwardly over the valve casing to the positions illustrated in Figures 3 to 5 with the hood 30. overlying the outlet ports 17 for directing the water in a downward direction for eliminating undue splash of water discharged from the valve casing.
From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that the valve 18 is freely mounted within the valve casing and the float arm 20 pivotally connected to the upper end of the valve has fulcrum engagement with a side facet 24 of the cap nut 23 so that when the float rises to the position shown in Figure 1, with the side facet 24 of the cap nut acting as a pivot for the float arm, to cause the valve 28 to be lowered upon its seat. 16. The heightiof the-waterin the tank 10 may be regulated by adjusting the cap nut 23 upon the upper end of the valve casing 13 to vary the throw of the float arm 20 and further adjustment of the valve 18 may be accomplished by the pin and thumb nut attachmentfor the float 28 upon the outer end of the float arm 20.
While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed I claim: -1. Valve" mechanism. comprising av casing having a. valve seat therein, a valve freely movable in the casing for. engagement with :the seat, said. casing being longitudinally" slotted, a cap nut.
threaded on the casing overlying a portion of the slot and a float arm extending through the casing slot and attached to the valve and having fulcrum engagement with an edge of the cap nut for closing the valve on its seat, said cap nut being of polygonal form defining side facets with a notch in the lower edge of each facet to receive the float arm.
2. Valve mechanism comprising a casing having a valve seat therein, a valve freely movable in the casing for engagement with the seat, said casing being longitudinally slotted, a cap nut threaded on thecasing overlying a portion of the slot and a fio'atarmextending through the casing slot and attached to. the valve and having fulcrum engagement with an edge of the cap nut for closing the valveon its seat, said casing having lateral outlets therein and a hood carried by the casing and surrounding the outlets, said cap nut being of polygonal form defining side facets with anotch in the: lower edge of'each facet to receive
