FLOAT-VALVE.

Specification of Letters Patent.

' Patented Merch 3o, 1909.

Application led June'l, 1907. Serial No. 377,682.

.l 'To all whom it may concern:

Be it known that I, GOTTLOB E. LOEBLE, a citizeny of the United States, residin in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a .certain new and useful Imrovement in Float-Valves, of which the folowing is a specification.

, The invention relates toself-closing valves ofthe ball-cock class, and its object is to provide a simple, inexpensive valve` with a closing-float, which shall be positive in operation and not liable to derangement.

. the tank.

,through the valvecasing and iioat, on a f The invention consists in certain novel features and details of construction by which the above objects'are attained, to be hereinafter described.'

The accompanying drawings form a .part of this'specification and show the invention las applied to flushing-tanks.

Figure 1 is a vertical section through a tank,A showing the valve-casing and its conl nected parts in elevation. In this form the water supplgf enters through the bottom of `ig. 2 is a corresponding section larger scale. Fig. 3 is a lan view of the float.- Fig. 4 1s a section t rough a portion f of a fiushing-tank, on the same scale as Fig.

' any ordinary 1, showing the invention adapted forservice with ay suppl -pipe entering the side of the tank. The oat is shown in section, with the valve-casing in elevat on. ,-Fig.''5 is a vertical section, partly in e evation, showing on a larger scale the valve in the preceding' figure.

Similar letters'- of reference indicate like parts in all the figures.-

Referring to Figs. 1, 2 and 3, A is the tank adapted to receive water through a supplypi e Brat the bottom and deliver it ,through a ushi'ng-valve C and flushing-pi e C, operated by a lever D fulcrurned on a ar extending across the tank, all of which may be of or approved construction. The valve controlling the inlet comprises a casing E within the tank, screwed upon the end of the lpipe B and` having a horizontal diaphragm J on the lower face of which is a valve-seat F receiving a conical valve G on a verticallvmovable valve-stem H guided in s iders above and below the diaphragm El. 'lille upper or delivery end of the casing E is open to allow water to flow freely' therethrough when the valve is depressed, and is `flushing-valve reseated by gravity;

covered by a dome-shaped hood or dellector I attached by arms I1 to a screw-threaded ring I2 screwed on the upper end of the casing, serving to interce t the vertical jet therefrom and deflect t e water downward toward the bottom of the tank. The valvestem lII extends loosel throu h the deflector I and is continue vertieIly upward,

terminatin in a head or disk K immediately- A below the ong arm of the lever D and arranged to be struck and forced downward thereby to o en the valve by the act of raising the fius ing valve C. Onthe valvestem, above the deiector, inclosing the latter and a portion of the casing E, is secured the float L which is in the form of an inverted cu closed at the top, through which' the valve-stem extends axially, and open at the bottom. It is so located relatively to'the valve and tank as to yrise and lift the valve,

` and shut off the supply when the Water level has risen to the helght in the tank to which4 the float has been set.

Assuming the tank to' contain a supply of water, a downward ull on the long arm of the lever D lifts the ushing-valve C and'per-` mits the water to escape through the `Ilush1n9; pipe Cl until the lever is released and the downward movement of the lever-arm depresses the valve G in opposition to the pressure in the pipe B and permits water therefrom to flow past the valve into the no w empty tank. The valve is held in the open condition by its gravity and that of the float and valve-stern, and the flow continues until the water level rises sufficiently to im rison a volume of air in the open-mouthed) float and the displacement thus produced raises the float and lifts thevalve to its seat, the closing movement being aided by the current of water flowing )past 'the valve in the direction to close it. I closed it is held to its seat by the water pressure until the valve-stem is again forced downward The action is similar in the arrangement shown in Figs. 4 and 5. In these figures the supply-pipe B1 is at the side of the tank A1 and joins a valve-casing E having a downwardly projecting portion E3 having a diaphragm E4. 'The valve-seat'F1 is on the upper face of the diaphragm. In this form the pressure side, and the valve Gr1 o ens upwardly. Guides J receive the va ve-stem the Samet hen the valve is thus as at h to receive the end M1 of a lever M fulcrumed at m to a downwardly extendinglug E5 on the valve-casing E3. On the lever M is a iloat L1 similar to the float above described. The action is the sanfe as in the first form excepting the valve is lifted fro'm its seat by the gravity of the ioat L1 acting through the lever M instead of being acted upon by the ushing lever. Water flowing past the valve Grx gradually fills the tank until the loat L1 rises and draws the valve downward, in the direction of the flow, to its seat on which it is held as before by the service. ressure until overcome by the gravity of t e float LL as the latter descends.

In both forms the valve is seated in the direction of the current, and is held in the closed condition by the water pressure, thus avoiding danger of lleak and obviating the' use of stufling-boxes or like devices, and the cup-shaped iloat reduces the expense and f annoyance attending the employment of the usual -water-tight ball.

Especial im ortance is attachedV to the form shown in lgs.y 1, 2, and 3 on account of its simplicity. The direct attachment ofthe float concentrically to the valvestem reduces the number of parts, and lessens the vexpense of manufacture; this construction also effects a considerable `saving in space, thus permitting the valve to be installed and operated successfully in narrow quarters.

I claim l y 1. Ina float valve device, a tank, a casing therein mounted upon the supply pipe and having therein a horizontal diaphragm with a valve seat on its underside, a 'vertically v movable valve stem, guides therefor above and below the diaphragm, a conical valve on said stem, the up erxend of said casing being open, a dome-shaped hood supported from the upper end of said casing and having a central opening through which the valve stem passes, and a iioat sup orted on said stem, concentric with said Eood, with its lower end extended below the lower edge of the hood and forming an airv chamber around a valve seat on its under side, a vertically movable valvefstem, guides therefor above` and'below the diaphragm, a conical valve on l'said'steirL the upper end of said casing being open, a dome-shaped hood supported from the upper end ol" said casing and having a central opening through whichthevalve stem passes, and a ioat sup orted on said stem, concentric with said ood, with its lower end extended below the lower edge of the hood and forming an air chamber around the hood and between the same and the wall of the 'float both above vand below said hood, said casing being formed of detachable parts and the hood being vertically adjustable on the uppermost of said parts.

3. In a float valve' device, a tank, a casing therein mounted upon the supply pipe and having therein a horizontal diaphragm with on said stem, the upper end of said casing.

being open, a dome-shaped hood supported from the upper end of said casing and having v a central opening through which the valve stem passes, and a float sup orted on said stern,l concentric with said lifood, with its lower end extended below the lower edge of the hood and forming an air chamber around the hood and between the same and the wall of the float both above and below said hood, said hood being detachably secured upon the upper end of the casing and saidffloat being directlyl attached to the valve stem and concentric therewith.

In testimony that I claim the invention above set forth I affix my signature, in presence of two witnesses.
