Application filed August 10, 1995, Serial No. 273.509.

To all whom it may concern:

Be it known that I, J OHN H. DAv1s,,a citizen of the United States, residing at Hamilton, Butler county, Ohio, -(post-ofiice address No. 229 North Ninth street, Hamilton, Ohio,) have invented certain new and useful Improvements in BalLCocks, of which the following is a specification. 1

This invention, relating to that class 0 float-controlled supply valves employed in connection with tanks and generally known as ball cocksaims to improve such cocks by better adapting them for use with water of a kind liable to clog metal valve-parts working in contact, and to secure ready rcmovability of the working parts. The cock is of that type employing a Compound lover system between the float and the valve proper. Y

The improvements will be readily under stood from the following description taken in connection with the accompanying drawing in which V Figure 1 is a side elevation of my improved ball cock: Fig. 2' a vertical section of the same: Fig. 3 a vertical section through the valve chamber in a plane at right angles to the plane of the section shown in Fig. 2: and Fig. 4 a front elevation of one of the leverjoints.

In the drawing :-1, indicates the valve body, being a casting adapted to seat upon the floor of a tank, as usual: 2 the inlet nose thereto, adapted, as usual, to go through a hole in the floor of the tank and have the supply pipe coupled to it below the tank: 3, the usual gasket to be clam ed between the valvebody and the floor of t e tank: 54, the valvechamber, within the valve body 1: 5, the roof of the valve-chamber, the same being provided with' an upwardly projecting central boss havin a circular aperture: 6, the valve proper, ein markedly smaller diameter than said circular aperture, through which it extends without contact and having its lower end faced with rubber or analogous material, the u per end" of the valve proper being bifurcated 7, the inlet to the valve-chamber, the same being formed by a central aperture extending through a boss extendin upwardly from the floor of the valve-chain er, the annular top of this boss forming the valve-seat against 'which the lower end of'the valve proper seats: 8, an umbrella flange surrounding the a cylindrical plug of valve proper above the roof boss through which it projects, this flange coming as closely down to the top of the boss as is consistent with the proper seating of the valve in its original condition and in such condition as is liable to result from continued use: 9, a bifurcated arm projecting rigidly up from the valve-body, parallel with the axis of the valve proper, and to a point some distance above the latter: '10,, the float lever, pivoted in the upper end of arm 9, the long arm of this float lever projecting over but at all times free from the valve proper, and being adapted to carry the usual float, the short arm of this float lever projectingoutwardly from arm 9: 11, the pivot connecting the float lever with arm 9: 12, a bifurcated arm projecting rigidly upward from the valve body at a point diametrically opposite arm 9: 13, a secondary lever having one end pivoted to the arm 12, and an intermediate point pivoted to the bifurcated upper end of the valve proper, the longer arm of this secondary lever projecting through the bifurcation of" arm 9, below the pivot 11in the latter, and to a point outwardly beyond arm 9 so that .its outer end is below the outwardly projecting short arm of the float lever: 14, the pivot connecting secondary lever 13 with arm 12: 15, a link connecting the end of the long arm of the secondary lever, with the end of the short arm of the float lever and having such length that the secondary lever will be substantially horizontal when the .valve is, closed: 16, the pivot uniting the upper end :of link 15 with the float lever: 17, the pivot uniting the lower end of the link with the secondary lever: 18, the pivot uniting the secondary lever with the valve pro er:-19, outlet ports in the base of the wal of the valve-chamber: 20, deflecting shields projecting outwardly from the valve-body over these ports: and 21, a small pipe leading out-- wardly from the valve chamber.

In the drawing the valve is seen in closed position, in which action of the float t ough the medium of the compound leverage. The pressure is directly downward axially upon the valve proper, its body being entirelyfiee from contact with and having considerable clearance on all sides from the wall' of the aperture in the roof of thevalve chamber, the secondary lever centering and reventing its displacement.

account and because of other features of con struction the valve 1s nolseless in operation.

- The upper end of the valve pro er,when

thevalve is either 0 en or close is supported by the secon ary' lever- 13 bridging the spacebetween'thefarms 9 and 12 and guided sidewise in the'bifurcations of those arms. The valve proper .is'thus supported in all directions at. its upper end through the medium of the secondary lever.

In Fig. 4 the form of pivot-14 is'shown, .the

1privot being removable by being unscrewed om arm 12, the bend in the outer end ofthe pivot forming a convenient handle for turnmg it. The

pivots

11 and 14 are to be of the removable type indicated in. Fig. 4 a'nd"it is pgreferable that pivot18 "also of this type.

y removing pivots

11 and 14, all of the movmg parts may be removed upwardly for inspection or repair, it not being necessary to remove the valve body from the tank.

Pipe 21, serves, in the usual'manner, in connection with the reseal if the ball cock is usedin connection with a closetreq u-iringsuch feature. This pipe ma serve in the usual way to discharge resea 'ng water into the flush ipe while the flush valve is open. When t e valve is open and the supply water is discharging into the tank through ports 19 the low-down location of those ports insures a complete'washing out of the valve chamber, thus preventing the accumulation of foreign matters at the face ofthevalve seat.-

- When the valve is open the valve plug lia'ngs as' a freely suspended structure, hangmg by pivot 18.

he engagement of the upper end of the plug with-lever 13 is such that the upper end of the valve can shift in neither direction, being revented from shift-mg endwise of the lever y the fitting of lproper rises and falls. The result is.

pivot. 18 in both the lever and the valve plug, while it is prevented from shifting in the otherdirection by the straddling of the lever by the upper end of the valve plug. While the valve is thus open water entering the valve chamber has two outlets, the main one being through ports 19 disposed below the level of the roo of the valve chamberw-hile the secondary outlet is upward through the roof of thevalve chamber around the valve plug. While the water is .flowin past the. open valve there is thus a low,was in effect at the valve-seat and also a-high leve wash ing efiect where the plug passes through the chamber roof. The valve is in practice found capable of perfect practical results, as to performance and maintenance, under peculiarly bad water conditions where other valves have given very serious trouble. The upward rush of water through the roof of the valve chamber around the valve plug is prevented from spouting upward 'by reason of the presence'of the um rella flange. This flange is disposed some distance above the top of the roof hole through which the valveplu works so as to give at all times a free out et sidewise to the water passing upwardly around the plug.

I-claim-as my invention In a ball cock, a valve'chamber having a supply inlet and valve seat in its base and an having a discharge outletsidewise in its base, a valve-plug with its foot resting upon and opemng concentric therewith in its roof and closing said valve-seat and having its body I rojecting through the opening in the roof es of contact therewith, an' umbrella flange carried by the valve plug above the annular discharge opening within the roof opening around the valve-plug so as to permit free sidewise discharge of the water passing up wardly through said annular opening, a lever mounted-on a fixed pivot and crossing the valve plug at its upper end and having sidewise engagement therewith'so that the valve plug may not shift sidewise relative to the lever, and a pivot en aging and fitting the lever and upper end 0 the valve plug in such manner as to prevent the shifting of the upper end of the valve plu endwise ofthe lever,"combined substantia y as set forth, whereby when the valve plug is raised it is freely suspended by its upper end and whereby the flowing water is given a low side outlet at the valve-seat and an upward and sidewise outlet above the valve chamber.
