2 Claims.
This invention relates to combined silencing and anti-siphoning means for water closets or other water or liquid containers adapted to be supplied with 'water or liquid from a source of 5 supply under'pressure such as the customary water supply system commonly employed in connection with such tanks, and an object of the invention is to provide simple and highly effective means whereby water can be conducted to the tank in an almost silent manner and for automatically opening the hush or filling tube of the tank to the atmosphere as soon as the water in the tank. has reached the intended level. l5 Among other importantfeatures of the invention, the following are illustrative of those upon which particular stress is laid:
To provide means broadly which will function as above set forth and whicl will include a highly novel arrangement of parts enabling convenient adaptation of the invention to the customary ball cock without requiring any great alteration in the construction thereof;
To provide` anti-siphoning means for auto-` matically :establishing communication between the filling tube and the atmosphere, hence between the source of supply and the tank as soon as the tank is lled and for automatically preventing such communication during the interval that the tank is being filled, the arrangement being such that the pressure of the water in its movement to the tank will render automatic the action of the mechanism employed; i
To provide a valved automatic vent for the lling tube which can be wholly incorporated in the iilling tube;
To provide a valved automatic vent, the effective elevation of which is always above the intake port of the ball cock to thus insure proper venting of the supply line in time with the filling operation;
To provide an anti-siphoning means and silencer which, when embodied in the filling tube, will not add materially tothe manufacturing cost of the tube; 1
To provide an anti-Siphoning and silencing means which will be positive of operation under all customary conditions and fool-proof and not apt to be readily placed out of order; 50 To provide a valve in the filling tube, `the form of which will servey in the regular operation thereof to prevent formation of incrustationof the walls of the bore of the chamber in which the-valve works, thus eliminating a probw', able cause for rendering the valve inactive at critical periods in the operation of the mechanism.
With the above and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, il- 5 lustrated in the accompanying drawing, and set forth in the claims hereto appended, it being understood `that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit of the invention.
In the drawing,
Figure 1 is a view partly in irregular vertical section and partly in elevation showing the in- 15 vention applied;
Figure 2 is a vertical section through the filling tube and a portion of the ball cock;
Figure 3 is a view somewhat like Figure 1 showing the position of the filling tube valve to close the atmospheric vent of said tube as when water is flowing to the tank from a source of water supply under pressure;
Figure 4 is a horizontal section taken on line 4 6 of Figure 1; 25
Figure 5 is a section on line 5 5 of Figure 1; i
Figure 6 is a perspective view of the valve element of the filling tube valve.
In carrying the invention into practice,- T represents a water-closet supply tank; P the vertical pipe adapted to be connected as customary, with a source of water under pressure; B the ball cock atl the upper end of pipe P, the same Ahaving a valve seat S and a co-operable vertically movable ball-controlled plug Piconnected by the usual linkages L to the float rod R. When the rod Ris'fully raised,theplugPl closes the intake orifice O in the seat S and admission of water to the ball cock ceases. When, however, the rod lowers, the plug is raised and water will pass to the outlet OI of said ball cock. All of these features just above described are old and well known in the art and are merely referred to herein as a means of disclosing the intended relationship thereof tol each other and to the J features embodying our invention, as will unmistakeably enable any person trained in the art lto practice the invention.
The outlet OI includes a short lateral nipple or boss i i) into which is threadedly fitted one end of a short tubular extension I I of a vertical valve casing I2, the upper end of which is located above the outlet OI. The lower end of said casing has the upper end of a filling tube I 2 fitted thereto to pass water to tank T. The tubular extension Il traverses the bore oi the casing I2 as shown in Figures 1, 2 and 3 of the drawing and is formed with an upwardly directed outlet orifice I3, disposed axially of the casing bore and thereby adapted to direct a jet of water upwardly into the cupped underside of a verticallymovable valve element I4.
meanediy 'nti-,ed in the upper end ocrthe 'casing I2 is a valve seat I5 against which the ilat upper face of the valve I4 can seat by virtue of the -force of liquid directed into the cup of said element, thereby closing the atmospheric vent orice I6 so long as liquid is flowing through the casing. 'Ihe seat I5 is formed with a crown I1, spaced apart from the lower portion of the seat to thus provide'annular ducts I 8 by means of which air may enter the casing from above the level of liquid in the tank.
It will be understood that the valve element Il is proportioned with respect to the distance between the seat I5 and the tubular extension II so that it is entirely free to move vertically a distance limited only by said extension and said seat and that it is thereby adapted to freely rest upon the extension when the ow `of water through the casing ceases. Thus, the cup in the underside of element I4 directly confronts or faces the orifice I3. It will be further noted, particularly on reference to Figures 5 and 6 that the element Il is provided with substantially hexagonal ends 1 I9 and 20 and an intermediate reduced cylindrical body portion 2i, the diameter of the latter being less than that of the diameterof the bore of the casing I2. This provides sharp edges at the intersection of the 'at faces of the ends I9 and 20 adapted to have scraping contact with the walls ofthe bore of the casing` such as will hold samein a smooth clean state and free from foreign matter and incrustation or scale.
The operation of the invention is as follows:
In Figure 3 of the drawing, let it be assumed that water is flowing under ordinary city pressure through the ball cock and into the casing I2 of the filling tube. 'I'he valve element Il which normally rests upon the tubular extension I I andhas its cavity or cup disposed directly over the orice I3, will be raised by the pressure of the water to thereby take the position shown in said gure, during which time the vent orifice I6 is closed to prevent air from. entering the casing I2. By reason of the fact that no air is permitted to enter the system during the tank filling operation, it follows that the water is silently delivered to the tank. As soon, however, as the plug PI falls to its closed position following full raised position `of the oat rod R, the valve element I4 falls by4 gravity to the position shown in Figure 1. In so doing, the atmospheric vent orifice I8 is uncovered and air will enter the valve casing I2 and thereby break a vacuum induced in pipe P. In Figure 1, W indicates the approximate level of water in the tank when the rod I4 is fully raised, and it thus follows that the casing I2 is. devoid of water when said tank is lled. It is for this reason that suction induced in the ball cock or pipe P will be promptly broken, such as will vprevent water in thetank from' returning to the pipe P by slphonic action.
While' we have shown a specific form of valve element Il, the function of which is to open and close communication between the tank T above the normal level of` water therein and the pipe P, it is to be clearly understood that we are primarily concerned with the provision of any equivalent of said valve which will function timely withthe familiar operations of the ball of the rod I4.
What is claimed is:
1. A device of the class described comprising a valve casing having a chamber provided with an upper` atmospheric vent and a lower outlet adapted for connection to a illling tube; the casing having a tubular inlet portion vadapted for connection to the outlet of a ball cock and extending across said chamber with an upwardly opening port n such portion through which water from the ball cock can discharge upwardly into the chamber; and a valve element working in the chamber between the atmospheric vent and said tubular portion t'o rest upon the latter and open said vent so as to place the chamber in communi-` cation with atmosphere when no water is flowing from the ball cock, and ,to be elevated to close said vent by water from the ball cock discharging -into the chamber through said port.
2. A device of the class described comprising a valve casing having a chamber provided with an upper atmospheric vent and a lower outlet adapted for connection to a illing tube; the casing having a tubular inlet portion adapted for connection to the outlet of a bali cock and extending across said chamber with an upwardly opening port in such portion through which water from the ballcock can discharge upwardly into the chamber; and an inverted cup-shaped valve element working in the chamber directly` abo-ve the port of said tubular portion to normally restt upon the latter under the action of `gravity and open said port so as to place the outlet ofthe ball cock in communication with the atmosphere through said vent, chamber, interior of valve element, and ported tubular extension, and to be elevated to close said vent by water from the yball cock discharging into the chamber through said port.
