9 Claims.
My invention relates to improvements in a water control for closets, particularly of the low tank type.
More specifically, the invention pertains to improvements in a water control relating to that part of the closet tank which is known in the trade as a ball-cock.
Among the more important objects of the invention is to improve upon the float valve mechanism of the ball-cock whereby a more effective silenc ng of the flowing water is accomplished; to improve upon the mechanism of the ball-cock whereby a simpler and easier functioning antisyphoning means is provided; to improve upon the lift lever assembly whereby a wider range in water pressure systems is accommodated, thereby eliminating the use of water regulators; to provide as an article of manufacture an improved plunger adapted to be sold in the trade with sink faucets and the like for breaking up the water and acting as a silencer; and to provide in a ball-cock an improved one piece casting extending from the bottom of the tank to the bottom of the syphon breaker.
Still other objects, features, and advantages of invention will hereinafter appear.
Referring to the drawing wherein is shown a preferred embodiment of the invention as now reduced to practice.
Fig. 1 is a side elevation of the improved ballcock assembly shown positioned in a closet tank and associated with a conventional flush valve,
the tank being shown in section and containing a body of water, the rise and fall of which opens or closes the stop-cock of the assembly.
Fig. 2 is an enlarged vertical mid-section showing the device per se withthe parts in closed position like that in Fig, 1, a portion of the structure being broken away to shorten the view. Some elements of the device are shown in side elevation and a floor portion of the closet tank is included in the view.
Fig. 3 is a section-similar to that shown in Fig. 2, but with the movable parts in functioning position.
Fig. 4 is a section taken on line 4-4 of Fig, 1.
Referring in detail to the drawing and to the figures as a whole, the water control comprises in general a ball-cock assembly 4, including the float rod 5, the float B for actuating the float valve 1 of the ball-cock, and a re-fill tube 8 associated with the over-flow pipe 9 of the flush valve I 0.
The ball-cock 4 and the flush valve ID in Fig. 1 are shown mounted and operatively positioned in the closet tank I l. The ball-cock is connected to a source of water supply l2 through the medium of the shut-ofl valve l3, the supply pipe l4, and the combined conventional couplingnut and washer connection l5. There is also provided a cone washer l6 and lock nut II for joining the ball-cock in a leaf proof manner with the fioor portion I If of the tank.
The numeral 18 indicates the tubular body portion of the ball-cock which is shown as a one piece casting which extends from beneath the floor of the tank to the cap structure I9 wherein the breaking up of the water and the anti-syphoning mechanism is housed. The upper portion of the casting is externally threaded at 20 whereby to screw the cap structure I 9 thereon. The purpose of this detachability will be explained later on.
Adjacent the lower threaded end 2|, the casting is provided with an annular flange 22 which has a bottom flat face 23 against which the washer is wedged when the lock nut I1 is tightened, thus compressing the washer to make a leakproof joint with the floor of the tank.
At apoint 24 in a downwardly spaced relation to the mouth or upper end of the casting 18 there is provided an internal screw-threaded portion l8s whereinto is screwed one end of the valve seat 25. Said seat is provided with an internal bore 26 concentric with the axis of the casting. The body portion 21 of the valve seat adjacent the threads is reduced in size and constructed of a polygonal shape to provide for the application of a socket wrench thereover whereby to render the valve seat detachable.
Adjacent the portion 21 the valve seat is further reduced to a cylindrical shape 28 and the end rounded off to provide a valve seat 29 for the plunger or float valve 1 presently to be'described.
The upper end of the casting is internally machined to provide a working surface along which the plunger 1 travels when it is elevated from time to time. The plunger is of an inverted cup shape to provide within it a chamber 3|, and in said chamber is mounted a washer 32 which normally rests on the seat 29. and at such time a considerable portion of the valve seat extends into the chamber 3| as shown in Fig. 3.
The plunger is provided with a stem 33, and on the stem is slidably mounted the anti-syphon, anti-splash washer 34. The external peripheral wall of the plunger is spiral grooves 35 and. 35a through which the water passes from the casting to the tank.
The function of the grooves is to divide the provided with a pair ofequallyas well to break up the water and silence On the upper end of the casting I screw the cap structure l9. Said structure has a cylindrical portion 45 which is threaded at 4| to mate with the thread 20, and when the casting and cap are fully attached the end of the casting forms a seat 42 whereon the washer 34 rests when the ball-cock is not functioning.
The cylindrical part 40 is provided with a closure 43 which is provided with a hole 44 concentric with the axis of the casting through which the stem 33 operates.
The stem 33 abuts against the lower side of one of a pair of tandem contacting levers 45 and 45, the closure part 43 being provided with a bifurcation 41 wherebetween to pivot the lever 45 by means of the cotter pin 48.
Arranged circumferentially in the cylindrical part 4|) adjacent the closure 43 are a plurality of radially extending, anti-syphon holes 43.
To the part 40 I attach as an integral part the spout 50, provided with the passage 5|. The outlet end portion of said passages is internally screw-threaded and therein is screwed the tank fill pipe 52. n the spout 55 I provide an upward extension 53 which is bifurcated at 54 and in the bifurcation I mount the lever 45 by means of the cotter pin 55. A stop 55 1s provided on said extension whereagainst the lever 45 rests when the tank H is empty. The lever 45 is threaded at 51, and the float rod has one end screwed thereinto, while to the opposite end is affixed the float 5.
The washer 34 is provided with a sleeve portion 34s, and this sleeve is slidable on the stem 33, together with its downwardly fiaredportion 34].
Said washer is cupped in order that the water egressing from the groove 35, 35a will travel first along its cupped face thereby exerting a lifting action avoiding any tending of the washer to tilt, which would promote friction between the sleeve and stem.
An annular stop ledge 55 is provided in the inner wall of the cylinder 40 to limit the upward thrust of the washer by the inflowing water at a point adjacent where the opening 5| enters the discharge chamber 59 as shown in Fig. 2. Thus, no air entering the holes 49 is entrapped within the pipe 52, and when the tank has filled. the washer gravitates to seating position, thereby permitting air to enter holes 48 and eliminate any tendency of the water in the tank to be syphoned back into the main supply line.
In order to compensate for variations in water pressures extending over a. wide range, I pro- .vide the compound leverage system as shown,
whereby suflicient force is attained by the action vof the water against the float to at all times actuate the plunger to a seating position upon the valves mouth 29.
The lever 45 has its pivoted end extended at 50 so as to detachably engage with the free end 5| of the lever 45. The lever 45 has a lower cam face 520. which engages the upper end of the stem 33 to exert a powerful downward pressure thereagainst under the urgeof the nose portion of the lever 45.
As the float 5 is elevated, the nose end 55 depresses the free end portion 5| of the lever 45 to force the plunger downwardly with added force to the position shown in Fig. 2.
The pipe 52 has its terminal end 52 somewhat flattened and beveled in order to direct the flattened stream which issues therefrom against the casting, or valve casing, l8 in a flatwise manner, to produce an additional initial silencing effect. This flattened pipe end also causes the water pressure to build up in the pipe so as to assure a slight overflow feed into the refill pipe 8 to provide for water in the bowl trap in case it has all been sucked out when the bowl is flushed. Y
A description of the operation will now be set forth.
In Fig. 3 the parts are shown in the relation they assume when the tank II has been emptied by operating the flush valve l0 in the usual manner.
In Figs. 1 and 2, the parts are shown in the relation they assume when the tank has been filled.
When the flush valve is operated, the float 5 follows the fall of the water until the lever 45 comes to rest against the stop 55. As the float gradually falls the lever 45 moves about its pivotal joint 55 in a clock-wise direction thereby elevating its nose end. Due to the freedom of pressure of the nose against the free end 5| of the lever 45, the pressure of the water in the casting, or valve casing l8 acts against the plunger I and in turn causes the stem 33 to move upwardly, thereby maintaining the contacting association of numbered parts 55 and 5|.
As soon as the washer 32 is elevated from its seat 29, water flows through'the grooves 35 and 35a and is broken up and silenced by them. On egressing under the washer 34 the water elevates the washer from the position shown in Fig. 2 to that shown in Fig. 3, said washer being guided in its upward movement by the sleeve 348 until its peripheral edge contacts with the annular stop flange 58, thereby permitting the water to flow through the spout openingv 5| and through the tank fill tube 52 into the tank. While the tank is filling, water is backed up in the pipe 52 due to its flattened mouth and a sub-flow is created through the 'reflll'tube 8 into the overflow pipe 9 for the purpose hereinbefore stated. The washer 34 also prevents the water from being splashed through the anti-syphon holes 49 and further aids in directing the water into the spout opening.
As the float gradually rises due to the rise of the water in the tank, the nose end of the lever 45 acts on the free end of the lever 45 to depress it, thereby gradually forcing the stem of the plunger downwardly until the washer 32 is fully seated and stops the flow of water. As soon I as the latter operation takes place, the washer 34 due to its weight and free working fit gravi-.
tates to rest against its seat 42, permitting air to enter the holes 49 and thereby preventing. any tendency. of the water to be syphoned from the tank into the main line whereby it mightbecome polluted.
By the peculiar construction of the lever mechanism I am able to control a much wider range of water pressure than is at present accomplishable without the use of auxiliary water pressure controls.
When it is necessary to make repairs, such as 'an-ti-syphon holes in the cotter pin 55 is removed preparatory to detaching the lever 46, and the cap alone is unscrewed, the other parts remaining in place. After the cap has been removed the plunger and washer may be lifted out and if necessary a socket wrench applied to the valve seatfor its removal. Thus, no lateral stress is placed on the joint connection of the ball-cock with the bottom of the tank whereby its leak-proof condition might become impaired.
It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.
