'5 generally improve upon and simplify the construction of the existing forms. of toilet tank flushing valves, to provide a valve of the character referred to that may be inexpensively manufactured and installed, to pro-- vide. a flush valvethat is practically silent in operation during flushing action and during the refilling of the tank, further to provide a device of the character referred to that is economical in the use of water and which is non-leaking when properly installed.
Further objects of my invention: are, to provide a flush Valve wherein-the pressure of the water from the source of supply, for instance the city water mains, is utilized for efi'ecting a forcible discharge of the water contained within the tank in which: the valve is located, thereby materially increasing the eifectiveness of the valve in accomplishing the flushing operation, and, further, to provide a flush valve wherein the pressure of the water from the source of supply is utilized for compressing air and which latter is eifective, whenthe valve is opened, in adding force to the flushing water as it discharges through the valve.
Further objects of my invention are, to provide a flush valve that will operate eifectivel y under comparatively low pressures as well as high pressures, toprovide a flush valve that is strong and substantial in construction and which has comparatively few operating parts, thereby minimizing'the liability of this valve becoming inoperative and inefiective due to failure of the partsto function properly, and further to provide a flush valve that may be located within the standard forms of water tanks that are now generally used in connection with toilet bowls, or in connection with tanks that are located in a building wall.
on the pressure flushing device disclosed in U. S. Letters Patent No. 1,566,769',-issued to me December 22nd, 1925, and also-my copending patent applications filed July 16.th, 1'926,
Serial. No. 122,815 and Serial No, 273,120, filed April 26th, 1928.
W'ith the foregoing and other objects in view, my inventionconsists in certain novel features of construction and arrangement of parts that will hereinafter be more fully de-. scribed and claimed and illustrated in the accompanying drawings, in which:
Fig. 1 is a vertical section taken through the center of a tank such as is ordinarily used in connection with toilet bowls and showing my 1improved flush valve associated with said tan V Fig. 2 is a vertical cross section taken the line 22 of Fig. 1.
Fig. 3 is a horizontal section taken on the line 33 of Fig. 1. 1 j
Fig; 4 is a vertical section showing my im1-- proved flush valve associated with a tank that is located within a building wall. 4'
Fig. 5 is a horizontal section taken on the line 5-5 of Fig. 4L. 7
Referring by numerals to the accompanying drawings which illustrate a practical einbo'diinent of my invention, 10 designates a tank of the type that is usually employed in connection with toilet bowlsand arranged within this tank, which: forms a. housing for my improved flush valve, is a pair of tanks 11,: preferably formed of sheet metah-and which tanks are made air and water. tight so asto contain water and air under'pressure.
' Located in the lower portion of tank 10 is'a vertically disposed cylindrical valve body 12 and leading from opposite sides thereof to the lower portions of the tanks; 11 are short tubular members 13.
Screw-seated in the lower end of the valve body 12 and leading downwardly'through an openingin the bottom of tank 110' is a" wa ter outlet or discharge pipe 1 1 that leads downwardly to the'bowl with which the fi-ushvalve is associated. i v
Leading through an opening in thebottom OIl 'oftank 10 and into one of the tanks 11 is My present invention is an improvement a water supply" pipe: 15 that isconnected to asuitabl'e source of supply, for instancethe' city mains, and the upper end of this pipe" which terminates in the upper-end? of the tank in which it is located, is connected by a T to a horizontally disposed pipe 16, the
' tions of the tanks 11.
Located in pipe 15 and within the lower portion of the tank 11 in which said pipe 15 is located, is a housing 18 containing an adjustable check valve 19 that is arranged so that it opens to permit water to flow upwardly through pipe 15 and which is also efiective in enabling the flush valve to operate with relatively low pressures.
Associated with this check valve is a spring 20 that normally retains the valve upon its seat and the tension of which spring may be adjusted so as to regulate the opening move: ment of said valve.
Screw-seated on the upper end of'the valve body 12 is a cap 21, and formed integral with the center thereof is an upwardly projecting housing 22. i
Extending through this housing and through an air tight bearing 23 on the side thereof, is a shaft 24, and mounted thereon, within the bearing 23, is a torsional spring 25 that yieldingly resists rotary motion of the shaft in one direction. Secured on the outer end of this shaft 24 is an arm 26, to the outer end of which is connected a vertically disposed link 27 and the upper end of the latter is connected to the inner end of a hand lever 28 that projects through an opening in the upper portion of tank 10, and said lever being fulcrumed at 29 to the wall of said tank 10.
The parts justdescribed provide means for manually actuating the flush valve through a partial rotation of shaft 24 and after said shaft has been partially rotated it will be returned to its normal position by spring 25.
Arranged within the upper portion of the valve body 12 and retained therein by the cap 21, is a diaphragm 30in the form of a disc of resilient metal that is covered with rubber or rubber composition, and extending upwardly through the center of this diaphragm is a short tubular member 31 that is externally threaded and screw-seated on the threaded upper portion of said member is the lower portion of a yoke 32 that occupies the chamber within the housing 22.
Secured on shaft 24 and disposed within the yoke 33 is a substantially triangular cam 33, one ofthe flat faces of which normally rests against the fiat under face of the upper portion of yoke 32.
The edge of diaphragm 3O rests upon a ring 34 that is positioned in the upper portion of.
Extending downwardly through the center of the diaphragm 35 is a short tubular member 36 and normally resting on a seat that is formed at the upper end of the opening through this member is a small valve 37 that is carried by a stem 38 and the upper portion of this stem is arranged for sliding movement within the tubular member 31, there being a pin and slot connection 39 between the upper portion of the valve-stem 38 and said tubular member 31.
The edge of diaphragm 35 rests upon a flan'ge40 that is formed integral with and projects outwardly from the upper end of a cylinder 41, which latter extends downwardly from the upper portion of the valve body 12 into the chamber within said body between the inner endsof tubular members 13.
This cylinder 41 is preferably composed of non-corrodible metal or it may be formed glass or vitrified earthen material having a glazed surface.
Formed througa the upper portion of the valve body 12 throughthe flange 40 and the ring 34 is a small duct 42, the upper end of which communicates with the chamber between the diaphragm 30 and 35 and seated in the upper portion of the wall of valve body 12 is an adjusting screw 43, the inner end of which is adapted to enter the duct 42 and control the flow of watertherethrough.
The lower end of duct 42 is enlarged to form a baflie chamber 44 and terminating within said baffle cha-mber is the upturn-ed inner end of tube 45, the outer end of which is connected to valve housing 18 at a point below the check valve 19 therein.
Arranged for sliding movement within cylinder 41 is a short cylindrical block 46 of non-corrodible metal, glass, or porcelain having a glazed surface. Formed in the underside of this block is a recess 47, the upper end of which is in communication with the opening through tubular member 36, the lower ,of the block 60.
Carried by the under face of valve 49 is a gasket 53 that is adapted to engage on a concentric rib 54 that projects upwardly from a ring 55 and the latter being screw-seated in the lower portion of valve body 12 just above the outlet pipe 14.
Formed through the valve 49, inside the rib 51 are ports 56 and which ports are inclined inwardly so that their lower ends communi Gate with the opening through ring 55 inside the rib 54. 3
Arranged in the chamber 47 in cylindrical member 46, is an expansive coil spring 57 that normally exerts downward pressure on valve 49.
Under normal conditions or while my im-' proved valve is at rest the various parts of the device occupy the positions as illustrated in Fig. 1. The water Within the tanks 11 under the same pressure as the water within the city mains or source of supply and the air that is trapped in the upper portions of the tanks'll above the water therein is under the same degree of pressure as the water.
Water under pressure occupies the chamber between the diaphragms and 35, thereby forcing said diaphragmsapart and holding cylinder 46 and valve 49 at their downward limits of movement so that gasket 53 rests on ring 54 and gasket 52 rests on rib 51, thereby cutting off the flow of water clownwardly through outlet pipe 14.
To actuate the valve, lever 28 is manually operated and through connections 27' and 26, shaft 24 is partially rotated and following the movement of triangular cam 33, yoke 32 will be slightly elevated and through pin and slot connection 39 stem 38 will be raised a short distance so as to withdraw valve 37 from its seat at the upper end of tubular member 36. V I
Following the unseating of this valve 37, which functions as a pilot valve, water under pressure will discharge from the chamber between the diaphragms 30 and 35 downwardly through tubular member 36, thence through chamber 47 and thence through opening 50,
into outlet pipe 14. As the Water pressure within the chamber between the diaphragms 30 and 35 is thus initially reduced, the diaphragm 35 will return to its normal straight or flat condition, thereby elevating cylindrical body 36 and valve 49 carried thereby, so
. that when said valve 49 is elevated as shown in Fig. 2, the outlet through ring will be open so as to permit the outward flow of water;
downwardly to form a depending nozzle 12 under pressure from the tanks 11 and this water discharging through pipe 14 will etiect the desired flushing action through the bowl with which the valve is connected. This discharge'of water from the tanks 11 will lower the pressure of the water, thereby permitting the adjustable check valve 19 toopenso it that water at the maximum pressure may flow upwardly through pipe 15, thence through pipe 16 and whichwater will discharge down wardly from the end portions 17 of the pipes 16 and thus the flow of the water from the tanks 11 will be accelerated during the flushnormal position so that cam 33, acting upon yoke 32, will move the same'and the dia,-:
Thus the main outlet opening is closed slightly before the body 46. reaches its downward limit of movement for valve 49. carry ing gasket 52 is forced downward under the influence of expansive spring 57 and following the seating of the valve 49,, as just described, any water that remains in the lower portion of the tanks may discharge through ports 56, which remain open until gasket 52 on the under side of valve body 46 engages the seat formed by the rib 51 and which action occurs when the body 46. is forced to. its downward limit of movement by the pressure that is built up within the chamber between the diaphragms 30 and 35.
- Thus after the valve is closed and suilicient water has entered the tanks 11 to compress air in the upper portions of said tanks to v a pressure equal to that of the pressure of the Water supply the various parts of the valve will be in proper position for a subsequent operation.
In Figs. 4 and 5 I have illustrated my improved flush valve-associated with a tank that is located in a building wall, preferably to the rear and above the bowl withwhich the valve is associated. In this construction the water supply pipe 15 leads upwardly through the tank 11 that is located in the wall and the upper end of said pipe is bent In this form of valve it may be found desirable to dispense with the adjustable check valve 19 and form in the housing 18 that is located in pipe 15 an inclined deflector 58 that is arranged to deflect a part of the water upwardly through the supply pipe into and through the pipe .45. that leads to the port that communicates with the chamber between the diaphragm.
'In this form of valve a spring held plunger 59 is arranged for operation'in the housing that projects upwardly from the cap 21 and formed in said plunger is a slot having an inclined portion 60. Passing through this slot is pin 61 that is seated in a member 62 that bears on top of the upper diaphragm and which corresponds to yoke 32. Carried by the outer end of plunger 59 is a disc 63 and bearing against this disc is the beaded edge of a'hemispherical body 6d that is arranged for operation in a socket blade 65 and said body being'carried'by the inner end of a handle 66.
To operatethis form of flush valve handle 66 is engaged and moved vertically orlaterally and the head 64 onthe inner end of said handle operating in its socket will bear against disc 63 and move the latter and the plunger 59 inwardly so that pin 61 rides up the inclined portion 60 of the slot in said plunger, thereby elevating member 62 that is connected r' to the upper one of the diaphragms and fol lowing this action the flush valve will operate as hereinbefore described.
Thus it will be seen that I have provided a flush valve that is relatively simple in construction, inexpensive of manufacture and which is very effective in performing the functions for which it is intended.
Among the especially desirable features of my invention are, the provision of means whereby the force of jets of water under pressure are utilized for accelerating the dis charge of water through the valve during flushing operations, the means whereby the pressure of water within the tank is utilized for closing the valves that control the out let of water from the tank and the various partsthat are combined to bring about the proper sequence the movements of the various operating parts of the valve when same is opened and closed.
In some parts of the country the character of water supplied for-domestic purposes is such that metal exposed to the water will corrode in a comparatively short time and where such conditions exist the cylinder t1, the
It will be understood that minor changes in the size, formand construction of the various parts of my improved flush valve may be made and substituted for those herein shown and describedwithout departing from the spirit of my invention, the scope of which is set forth in the appended claims.
