Specification 'of Letters Patent.

Application filed April 19, 1909.

lvlatented Feb. 24C, 1914. Serial No. 496,806.

To all whom t may concern ,l

Be it known that I, VILLIAM SYDNEY] (limitait, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Closet- Flushing .ilrpparatus of which the following is a description. reference being had to the accompanying drawing, which forms a part of my specification.

This invention relates to a novel construction in a closet flushing apparatus, the object bein to provide a device of this character which is simple in construction, that may be easily operated, and that will be l etticient, and noiseless in operation; and conl siste in features of construction and combil nations of parts hereafter' set forth. f

ln the drawing Figure l is a fragmentary central vertical section of a closet flushing apparatus constructed in accordance with my invention, showing the valve closed or in the position the apparatus occupies before the same is operated. Fig. 2 is a similar view showing the valve in its open position.

In all closet flushing apparatus in which the water iiows by gravity from a tank, a minimum water level is maintained in the tank, that is the tank is never entirely drained because the flow of water therefrom is interrupted by the closing of the outlet valve or breaking of the siphon before complete drainage. '.iherefore, in construction of that class, in order to provide a four gallon flush, for example, a tank of considerably greater capacity must be provided.

(verhead tanks are usually operated by means of a depending chain or its equivalent which is easily broken and is also undesirable; and furthermore, overhead gravity tanks are usually more or less noisy.

lily invention has for its object to provide flushing apparatus including an overhead tank which will be noiseless in its operation because of the fact that there will be no siphons to break, nor` will there be any pounding of valves; that will cause complete i drainage of the tank; that is easily and conveniently operated by means of a push button, and is less expensive than the valve l mechanism ordinarily provided for over head gravity flush tanks; and will enable a smaller tank to be used than is true with a sartene-J. y

My invention consists in interposing a valve in the outlet pipe leading from the Hush-tank or other source of supply to the closet bowl, to control the flow through the pipe: the valve being normally closed and so constructed that when raised from its seat it will be maintained in the raised position bythe pressure of the 'atei' flowing through the pipe, and close automatically when the liow of water ceases.

In the drawing, A indicates a flush tank and ll the pipe connecting' the tank with a closet bowl. ,interposed between the ends of the pipe l5 a *nivo-casing which is bulged between its ends and consists preferably of an upper portion (l and lower portion D secured together at the point of greatest dij ameter.

Mounted within the valve-casing is an inverted cup or hood E having a cylindrical mouth portion and provided in its conical upper wall with a central opening F. The open or mouth-end of the cup is secured to a ring r by means of radial arms H, said ring being confined between the opposed edges of the two parts C and D of said casing thus supporting said cup centrally within the casing. The member E is also preferably provided with an opening E located at the point indicated, so that when the valve J' is lifted, as shown in Fig. 2, the flange of the valve closes off this opening.

ln the bottom of the member D of the case ing and extending preferably slightly above the lower' most portion of the casing, as clearly shown in the drawing, is a valve-seat I on which the valve J seats; the latter being provided with a stem K projecting through the central opening .F in the upper member or cup E and being also provided with an annular peripheral iiange L, thus practically forming a cup-shaped member which is adapted to lit loosely within the cylindrical mouth portion of the member or inverted cup E. On the lower face of said valve J is a central projection M through which a central opening N is bored, the latter communicating through the lateral open- :ings O in the stem K with the interior of member or cup-shaped valve J. Secured within the flange P, preferably shown integral with member D of the valve-casing, is a spider Q having a central projection` or stud which is adapted to enter the central opening N in the projection M for obvious purposes.

In'the upper membei` C of the valve-casing is a lateral opening surrounded by a threaded flange S in which a cup T is received, which is provided with a central opening. Through the latter opening the plunger U, equipped at its outer end with a push-button or knob V, passes; a fluid tight joint being effected in a well known man ner. -Said plunger is maintained normally at the outer limit of its movement by means of a spring WV. The inner end of plunger U engages one arm of a bell-crank lever X, which is preferably pivotally secured at its elbow portion to an upwardly extending arm on the cup E. The other arm of lever X takes into a longitudinal slot on valve-stem K and serves to raise the valve J from its seat when plunger U is pressed inwardly and lever X rocked. The upper end of the valve-stem K is preferably7 reduced and threaded, to receive the lower loop of a link Y which is connected at its other end with the arm of a float Z in tank A; the float serves to open valve J when the water in the tank rises above the usual high level. The connections between link Y and said valve-stem K and lioat arm are preferably such as to permit float Zito drop without depressing valve J g this is effected in any well-known manner.

The operation of my device is as follows: Upon applying pressure to the button or knob V the lever X will be swung thereby raising the valve J from its seat. rlhe water rushes through the opening thus afforded and during its passage through the valvecasing is deflected so as to converge from all sides about the valve-seat I, which is preferably slightly raised, and with the shape of the casing, causes the water to become more or less jammed and compel an upward pressure on the under side of valve J, thereby serving to support the latter in its raised position. The valve maintains this position until the tank A and the upper portion of the pipe B are drained and as the force of the flow of water decreases the valve slowly closes by gravity. In order to insure the proper seating of the valve, which is preferably of light material, the opening E is provided in the upper member as described, so that a small quantity of water will enter, after the valve begins to lower and the open ing is uncovered, and flow onto valve J, thereby over-coming any possible tendency that member J might have to remain in its raised position. The water that enters onto the valve, either while the valve is on its seater through opening E after the valve begins to descend toward its seat, will drain through openings O and N while the member or valve J is olf its seat andvbefore projection R enters opening N. The projection or stud R, taking into the opening N, as shown in Fig. l, prevents leakage through the openings while the valve is on its seat.

l have shown and described a preferred construction embodying my invention, but this construction may be varied in some minor details without departing from the Spirit of my invention, and I do not wish to be understood as limiting myself to the exact construction shown and described, but
