This invention relates to siphon flush organizations and has for an object to provide new and improved means for flushing any desired type of apparatus by the maintain- 5 ing of an a'irseal within the apparatus, which airseal is broken for the purpose of initiating the flushing operation.
A further object of the [invention is to provide a device, immersed in the water employed for flushing purposes, which said apparatus shall maintain columns of water at various'heights dependent upon the pressure of the water in the tank and separated by the airlocks or seals, which columns of water commingle when the airseal is broken to initiate a siphon flush.
-.A further object of the invention is to provide a valve organization in association with said siphon organization, which said valve shall prevent breaking of the airseal until the level of the water in the tank has attained the proper height for initiating and main taining a flushing action. A further object of the invention is to provide, in combination with a siphon organization, a valve automatically opening when the water in the tank has reached a proper level, making it possible to break the airseal through the actuation of a manual valve but maintaining integrity of the airseal until such water level has been attained.
' A further object of the invention is to provide in combination with a siphon organization an improved type of overflow for taking care of excess water level. V
A furtherobject of the invention is to provide, in proper combined relation, a vsiphon-V.
ing flush apparatus, an overflow device for taking care of excess water, an automatic valve form maintaining the airseal within the siphoning apparatus, and a manual valve for breaking the airseal when the automatic valve is opened.
This invention is directed to other objects'and possesses other features of novelty and advantage, some or" which, together with the foregoing, will be hereinafter more fully set forth. y
- In the drawings p Figure 1 is a View of the device in elevation, mounted in a tank, showing the proper relation of the device to the tank and to the inlet control, and v i Figure 2 is a view of the device in vertical section showing not only the siphoning organization in section, but alsothe automatic valve; k I
Like characters of reference indicate corresponding parts throughout the several views. The improvedfiush, which forms the subject matter of this application, while designed primarily for use in water closets and the like, is obviously usable in other connections and is in no way limited to such utility. It will likewise operate successfully in what is ordinarily known as high, tank or low tank flush. The'tank 10 shown in the drawings, is intended merely to conventionally show a tank and no attempt has been made to make this showing correspond to any actual size, shape or construction.
From the tank 10, the flush pipe 11 leads in the usual manner with the inlet pipe12 controlled by the buoyant b-all 13 in substantially the usual and ordinary manner. The inlet control forms no part of the present invention and any type of inlet control may be substituteohit only being necessary that the water level in the tank to be controlled within reasonably accurate measurements.
Communicating with theoutflow pipe 11', is the siphoning organization. This comprises a housing 14. as shown at Figure 1, but it is to be understood that the shape and contour as therein-shown, is not essential to the invention and thatit maybe otherwise shaped within the scope. 1
Within thehousing. 14 is a continuous sinuous passage made up of the sections 15, 16, 17 ,and 18, these reference characters being employed not only to designate the passages themselves, but designate also thecolumns of water maintained in such passages. As shown in the drawings, these passages are all connected by curves at top and bottom. Such curved construction reduces skin friction of fiowingwater but is not otherwise essential to the invention. A
Assuming that by the operation of the float valve 13, the water level-in the tank is maintained at 19, then the water will rise in the passage 15 and the air compressed will cause the water in the passage 16 to recede raising the column of water in the passage 17. It will be obvious that the height of the water in the tank will be equal to the height of the column of water in the passage 15 plus the difference in the heightof the water in the passages 16 and 17. In other words, if the column of water in the passage 17 above the column of water maintained in the pas sage 16 is added to the column of water in the passage 15, it will exactly reach the water level 19. The parts are so proportioned that before the passage 15 is quite filled, the water in the passage 16 willbe depressed but not below the partition and raise the column of 'water in the passage 17 but not to overflowing point. In case of excessive rise the water in the passage 15 will overflow into the passage 16, but this overflow will not be suflicient to break the airseal and start the siphoning action as the water willmerely trickle down into the column passage 16, raising the column in the passage 17 to overflow and then trickle down the passage 18. The maintenance of the several levels is dependent upon the maintaining of the airlock in the chamber above the passages 15 and 16. While this airlock is maintained the structure will con-- tinue to operate as outlined. When the flushing has taken place and the water has been lowered below the lower end of the passage 15, there will still remain water to fill both the passages 16 and 17.
As the water in the tank fills up toward the level 19, the water will rise in the p'assage 15 and by reason of the air compression will force down the water in the passage 16 raising the water in the passage 17 to overflow, which overflowing will continue only until the normal water level has been attained and the rise of water discontinued. The levels will then be maintained as above outlined. Also in case of excessive rise of the water, the water in the pipe 20 will flow over the bend 20 and down through the passage 18 to exit, this being an auxiliary means to take care of excessive flow in case the-ball valve 13 fails to operate properly.
For breaking theairseal and initiating the siphoning, a manual valve 21 is provided. This valve shown is merely conventional and the lever 22 for operating is intended to'be extended to form a handle or a chain connection or any such other manner as the convenience of operation shall make desirable. If the manual valve 21 communicates direct- 1y with the pipe 23, the airsealmight be broken at any time. In case the airseal should be broken before the proper water level has been attained. the efficiency of the flush would be diminished and possibly operation temporarily interrupted. To prevent suchan occurrence, the pipe 23 leads to a housing 24:
which communicates with a housing 25 through the valved passage 26 and thence to the pipe 27 with the manual valve 21.
In case, therefore, the valve 28 is seated closing the passage 26, air cannot move through the pipes 23 and 27. In the housing 25 therefore, a cup 29 is carried rigidly upon the stem 30 of the valve 28 and at its lower edge dips into a body of mercury indicated at 31. A tube 32 extends downwardly to such position that the rise of the water will enter into this tube and the compression within the tube communicating through the passage 33 with'the interior of the cup 29 will raise such cup and therewith the valve 28. The level of the water in the tank is equal to the level of the water in the tube plus the weight of the cup and its associated parts. This is indicated by the line 3%, the difference in height of the lines 34 and 19 representing the weight of the cup 29, the stem 30 and the valve 28.
hen therefore, this Water level has been ra .d to the line indicated, the valve 28 will open. This permits the flow of air through the pipe 23 and 27 when the manual valve 21 is opened. When therefore, a sufficient amount of water has been introduced into the tank to form a suillcient flush, the valve 28 automatically opens so that at some later time and as desired, the manual valve 21 may be opened allowing the air in the passages 1 5 and16 to escape and the water in the pasage 15 to rise and fill the passage 16'and by eason of the height of water above these -I arts to continue the flow through the passages 17 and 18 thereby setting up and establishing a siphoning action.
The pipe 20, being immersed in the water and the lower end of said pipe extending to the lower end of the passages 15, the siphoning wi l not be broken until the water has receded to the level of the end of the pipe 20 and the lower end of the passage 15.
Within the passage 16, an equalizing pipe 35 is positioned extending outwardly above the water line and communicating preferably through a bend 36 with the pipe 23. In the cduction of air from the passages 15 and 16 by the opening of the manual valve 21, the rise of the water in the passage 16 will first close the lower end of the equalizing pipe 35 and thus overcome the surging of the water within the passages and insure a steady'flow and siphoning action.
It is believed that the operation of the device has been thoroughly explained as-the description has progressed and that further description of operation would merely be surplusage.
Of course, the siphon flush may be modified in various ways without departing from the invention herein set forth and hereinafter claimed.
