FLUSH-VALVE.
Specification of Letters Patent.
Application filed November 17, 1916. Serial No. 131,902.
To all whom it may concern:
Be it known that we, LEONIDAS D. Wns'r and ABBA I. CARNINE,-citizen's of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and usefullmprovements in Flush-Valves; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable supplying air to the interior ignated by the line 3-3 of others skilled in the art to which tains to make and use the same.
' Our invention has for its object to provide an improved type of flush valve which may be easily and inexpensively manufactured, yet one which will be highly eflicient and durable and will operate to advantage without the use of floats for holding the flush valve open.
A further object is to provide novel means for supplying the water to the flush tank and for permitting the entrance of the necessary amount of air when'the tank is being flushed. j With the foregoing general objects in view, the invention resides in certain novel features of construction and inunique' combinations of parts to be hereinafter fully described andclaimed, the descriptive matter being supplemented by the accompanying drawings which constitute apart of this application, and in which:
Figure l is a side elevation'of the improved valve showing the application thereetween a closet bowl and a flush tank, the latter being shown in vertical section 1;
Fig. 2 is an enlarged vertical section on the plane of the line 22 of Fig. 1;
Fig. 3 is a similar view on the plane des- Fig. 2;
Figs. 4 and 5 are horizontal sections on the planes of the lines H and 55 of Fig. 2;
Fig. 6 is a detail perspective view of the two crank arms which are mounted on the rock shaft used for opening the valve;
Fig. 7 is a side'elevation of a closet hopper, a flush tank, and one of the improved flush valves showing adifferent manner of it apper- Fig. 8 is an enlarged parts shown in Fig. 7 disclosing more par ticularly the'construction of the air injector; and 1 other suitable through an opening 'oted to a crank arm laterally from a rock of the tank; sectional view of Fig. 9 is a horizontal section offthe line 9-9 of Fig. 7
In the drawings above briefly described, the numeral-l has reference to a water-tight flush tank preferably having at its lower end a pocket 2, 3 designates a closet bowl, 4 the flush pipe rising therefrom, and 5 the casing of the improved flush valve.
The casing 5 is disposed vertically and is of, cylindrical formation, being provided near its upper end with an outstanding stop flange 6 and with external screw threads 7 above said flange for engagement with a threaded opening in the lower end of the pocket 2. The upper end of the casing 5 terminates in the form of a contracted neck 8 having a valve seat 9 at its upper end, the lower end of a valve cage or hood 10 being threaded on said neck as shown clearly in Figs. 1, 2, and 3. The cage 10 is formed with two or more suitable openings 11 for permitting the passage of water from the tank into the casing 5 when the flush valve 12 is raised from the seat 9.
The valve 12 is preferably formed of rubber and is secured byrmeans of nuts 13 or means on a vertical stem 14: which both rises and depends from said valve. The upper end of the stem 14 slides 15 in the top of the hood 10, while the lower end thereof is pivor arms .16 projecting shaft 17 which extends transversely across the casing, the latter having an external stufling box 18 through which said shaft 17 passes, and-having an internal bearing sleeve 19 which rotatably receives said shaft. The inner end of shaft 17 is received in a socket 20 formed in the inner end of a plug 21 threaded into one side of the casing 5 to give access to the interior thereof when assembling or repairing parts.
The outer end of the shaft 17 is equipped with an inclined crank arm 22 having on its lower end a heavy handle 23, the weight of this handle normally holding the shaft 17 in such position as to retain the valve 12 seated to prevent the leakage of waterfrom the tank. When,however, the handle 23 is raised the valve 12 will be lifted from its seat and will be partially confined in the upper endof the hood 10 so that the rush on the plane of water from the tank beneath the valve will serve to some extent to hold the latter in its elevated position. Other means to be described, however, is employed for positively holding the valve open until the tank has flushed.
The means above referred to includes a crank arm 24 extending from the shaft 17 in the opposite direction from 16, a vertical rod 25 pivoted to and depending from said arm 24, a pairof upper disks 26 and a lower disk 27. The three disks 2G and 27 are formed with central openings receiving the lower end of the rod 25 and the uppermost of said disks bears against a stop nut or the like 28 threaded on said rod, both of the disks 26 having perforations 29 for t'otal or partial registration to permit the discharge of water through the casing or passage 5 with more or less force. A sleeve 30 spacesthe disks 26 from the singledisk 27 which latter is also perforated, and a clamping nut 31 is threaded on the lower extremity of the rod 25 to clamp the several disks in operative position and to prevent relative movement of the disks 26 after they have once been adjusted. A port 32 extends along the upper portion ofone side of the casing 5 and opens at its lower end through a boss 33 tapped forthe attachment of a watersupply pipe 34 which may lead from any suitable source of supply A tank-filling nozzle 35 in the form of an elbow rises from the port 32 and at its upper end is concentric with and spaced a slight distance below the upper end of the neck 8, said nozzle thus serving to whirl the incoming water around said neck within the pocket 2 to silence the filling operation. 7 In operation, when the water supply is first turned on, the incoming water will compress the-air in the upper end thetank until the air pressure in said tank and the water pressure in the pipe 34 balance. henthis takes place be discharged from nozzle 35until the pressure within the tank 1 is reduced. The coinpressedair in the top of the tank 1 will condense to a large extent and will thus be absorbed by the water in the tank 1 with the result that when the tank is flushed it is necessary to permit the entrance of more air into the upper end of the tank to prevent the creation of a partial vacuum therein, it beingwell known that the existence of such a V vacuum materially decreases th e strength of. the flushing operation. The air eiiters' the tank through. the putt-lowing water in much the same manner as air enters abottle from which the contents are being poured.
hen the shaft 17 is rocked for opening the valve 12, it is obvious that the rod 25 will be soshifted as to slide the three disks 26 and 27 downwardly in. the casing 5, in which position they are held by the passage of water through said casing until the no more water will strength of flow. isdecreased to such an extent as to permit the force of gravity acting on .the handle 23 to overcome that of the downwardly fiowingwater. lVhen this takes place all parts are automatically returned to their initial positions by the weight of the handle, and the tank 1 again automatically fills in readiness for another fiushingoperation. During each of such operations, the disk 27 silences the same by checking the rush of water through the casing 5. The de vice gives a rapid and silent refilling of the flush tank; I
In Figs. 7 to 9 inclusive, the numeral 1 has reference to a flush tank, 3 to the closet bowl, 4 to the fiush pipe, and 5 to the flush valve casing. The construction of the latter is substantially the same as that of the easing 5, it being provided with a neck 8 similar to the neck 8, but the filling nipple 35 is omitted since the air is taken into the device through an injector 40 disposed in the pipe line 34' which is adapted to supply the tank 1 with water. The shaft 17, crank arm 22, and handle 23' are similar in all respects to the corresponding parts previously de- A tubular valve guide 47 is threadedinto the shank of the T 41 and is provided at its upper end with a valve seat 48 upon which a ball valve 49 rests, said valve having a depending stem 50 suitably guided in aspider or the like 51 and limited in its upward, movement by a stop nut 52. A perforated cap 53 is threaded on the lower end of the valve guide 47,-so that as the water passes through the Venturi tube 43 and suction is created in the'T 41, the valve 49 will open to permitthe entrance of air through the perforations of the cap 53,this air being supplied to the flush tank 1 to maintain the normal air pressure therein.
A tube 54 preferably leads from the lower end of the valve guide 47 and discharges into the lower end of the casing 5, said tube serving tojdirect any drippings from the a valve into said casing.
Fronr the, foregoing description taken in connection with the accompanying draw lngs, it will be obviousthat although the improve'clfiu'shvalve isofrather simple and inexpensive construction, it will be highly efficient and durable. For these reasons the arrangement of parts shown and described 40 includes a T coupling 41 i constitutes the preferred form of the device, but it is to be understood that within the scope of the invention as claimed numerous changes may be made without sacrificing the principal advantages.
We claim:
1. A flush mechanism comprising a passage having a normally closed valve at one end, means for opening said valve, a pair of contacting disks connected with said opening means and extending across the passage to permit the outflowing water to hold said means in position to retain the valve open, said disks having perforations for total or partial registration, and means for holding said disks against relative movement.
2. A flush mechanism comprising a passage having a normally closed valve at one end, means for opening said valve, a pair of contacting disks connected with said opening means and extending across the passage to permit the outflowing water to hold said means in position to retain the valve open, said disks having perforations for total or partial registration, means for locking said disks against relative movement, and a third perforated disk extending across the passage below the others for silencing the flushing operation.
3. A flush mechanism comprising a passage having a normally closed valve at one end, means for opening said valve including a rock shaft extending transversely of the passage, a crank arm extending from said shaft and moving toward the delivery end of the casing when said shaft is rocked to open the valve, a rod pivoted to and extending from said arm toward said delivery end of the casing, a stop near the free end of said rod, a pair of contacting disks extending across the passage and having central openings receiving said free end of the rod, said disks having perforations for total or partial registration, and a nut threaded on the rod for clamping said disks against the aforesaid stop.
4;.
