Application filed. February 6, 1921.7.` Serial No. 146,915..

To all whom, 'it ,may concern:

Be itknown that I, GEoRGEJoHNLAxIos, a citizen'of the United Statesresiding at Houston, in the county offI-Iarris and'Stat/e of Texas, have invented a newanduseful Float-Valve, ofV which the-V following is,l a speciiication.

This invention relates to new andjus'eful Improvements in a float valve. 1

The object of theI invention is to provide a valve of the` character described 'which may be used in tanks of :all kinds tocontrol the inflow of fluid intothe. tank after the tank has been emptied.

Another objectof theinvention resides in the provision of a device of the character describedr which is simple in construction and which may be easily and cheaply mann-y factured.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings wherein:-

Figure 1 is a vertical sectional view of the float valve.

Fig. 2 shows a plan view of a disk-likev guard employed in one form of the valve.

Fig. 3 is a side elevation partially in section of another form of valve, and l Fig. 4 is a side View of the valve showing the float lever removed.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral l refers to an inlet pipe whose lower end is threaded at 2 so as to screw into a corresponding socket in the bottom of the tank (not shown). The upper Vend of this pipe has an externally threaded head 3 to receive the valve casing 4 which is threaded thereon. Integral with,

and upstanding from, this casing is the standard 5 having the extended arm 6 which is formed into the ring 7. The standard 5 is extended upwardly forming two

extensions

8, 8, spaced apart and between which the floatlever 9 is pivoted and opposite these extensions and integral with, and upstanding from, the ring 7 are the guide lingers 10, l0, which are spaced apart and provided for the purpose hereinafter set forth. The

ring 7 forms a bearing for the, valvestem 11 whose lupper end carries the headf12 having the` Hat upper face Extendingoutfrom the stern is theguide l4whichrplaysbe.-

tween the ngerslOto prevent, `theastem fromturning and extending from the-,- head in the opposite; direction 4is.a.,catch\15;L The inner end ofthe float leveris formeddnto two oppositely disposed i ingespland-117',

thel `former of which fiszV curved` downwardly and its freeend restsagainstrtheflat face 13 lofy-thehead 12 and ltheilother .ofrwhich-, is upwardly curved andgalinedundenthe catch elevated, the' finger- .16 1 will fforce the Avalve downwardly and when the outer end of said lever y9 isl-lowered, the finger 17 Ywillengage Linder the catch l5 and lift said stem. The valve casing 4 is provided with an enlarged internal cavity '18 and the upper side of said casing has a restricted outlet 19 surrounding which is the valve seat 20. The lower end of the stem 1l is reduced to receive the concaved washer 21 and locked against the under side of said washer by means of the lock nut 22 is the rubber disklike valve 23.

In the form of valve used for toilet tanks and the like, the lower end of the stem is extended, as shown in Fig. l, `said extension being exteriorly threaded as at 24 and receiving a baffle 25 which is threaded on to the lower end thereof and alinedv above the baffle and the force ofthe current broken and the water will pass on out through the outlet 19 and will be deflected downwardly by the conoaved washer 21, thus preventing the water from splashing over the tank as is often the case when valves now in comA mon use are employed. In case the valve is used for outside tanks, such as are commonly used for watering stock, railroad purposes and the like, the stern is not extended below the lock nut 22, this form of valve being shown in Fig. 3, as for such use it isimmaterial that the water inflowing through the valve should splash over the tank.

It will be observed in the form shown in Fig. 3 that the washer 2l is made flat as in that form it serves only the purpose of backing and strengthening th@ Valve 23. In the form shown in Fig, 1, the outer end oi the Heat lever 9 is threaded to receive a suitable float (not shown) which will be lifted when the tank fills with water and will cause the valve to close. ln the form shown in Fig. 3, the valve lever is extended and its free end is shown formed to receive a float (not shown) Isuch as is commonly used in.

large tanks for watering stock, for filling railroad locomotives and for other similar purposes.

What I claim is:

1. A device of the character described including YVahollow casing provided with a valve seat, a standard upstanding from the casing provided with an arm which lis formed into a ring, guide ingers upstandingi :from the ring, a oat lever pivoted to the standard, a valve stem whose upper end is in operative connection with the float lever, saidV stemv operating through said ring as a bearing, a guide carried by the stem and playing between theV ingers, a valve secured to the lower end of the stem,

a deflector carried Vby the stem above the valve, and a baliie which projects through opea ef this patent may 'ne obtained for the seat and is carried by the lower end of the stem. Y v

2. A device of the charactert described including a hollow casingl provided with i catch extending from said head, the. iree end of one of the fingers of the'float lever resting against therlat face of said head and the otheringer of said float lever being alined under said catch, a concave washer carried by the lower end Vof said stem and a disk like valve securedv` against" the' under side of said washer.
