' The valve "22 is adapted to engage the seat- 16,- and'may be secured. "upon the stem in any desirable manner. In the present 'illus-j tration,rit is shownv'as'being threaded on to said stem,.and being held in adjusted position by meansof nhts 22 on the stem above and below said valve respectively. In practice, iwe have generally used the form of valve herein'shown, though it .will.

be obvious that a fiat faced valve, with a {valve seat to correspond, may be employed without in anywise departing from the spirit or" scope of the invention. By ad- "justably securing the valve upon itsstem,

the'same may beregulated so as to provide .for any desired throw of such valve. Carried 'bythe body 21 so as to seat upon the upper end of the casing 5 when the valve is open, is a washer 36 which prevents any.

water that leaks along the stem squirting upwardly over the tank, any such leakage being projected laterally within the'tank. Byfthis means weareenabled to dispense with stufling boXes-orother packing for the valve stem, which is usually a source of worry in connection with flush tank valves The casing section 5 is secured to the stand Section 6 by tap screws 37 which the flush valve (not shown) of the tank is opened," allowing the water in" the tank to 'escapathe fioat 3 5 descends under the action .of gravity, rocking the lever arm.'28 an leverarm 30 on pivot 27, and through the 1 connections of lever arm-26, with the lever 23'? tending to force thevalve stem downwardly. so as to unseat the valve 22 against- ,the pressure of the water-supply, allowing water to flow into the tank, until such time as the float is' again carried-upwardly by the rising water to a-pos'ition where the valve 22's'eats, and where it is firmly held against itsseat by the pressure in the water supply. V The arm 26 is preferably provided with a plurality of openings so thatadju'stment may be made between lever 23 and lever arm 28; adjustment 1112!) also be made of the valve 22, and also of the float by means in; for'any desired adjustmen Ye desire to callparticular attention to the construction of the valves'eatlfi and the valve 22. The valve seatis preferably of-the set screw 32 and 1ink 31, thus providmade tapering asshown for thereason that we have found in practice that if the valve 22' goes against-a blunt seat, the valve has a tendency torattle, whereas "by providing the tapering'-seat, and a correspondinglyshapedvalve, the seat forms a socket so that the valve pushes or pulls into the seat, gradually shutting off thepressure, and thus obviating any hammering of the valve.

[Having fully described our invention, what we'claim as. new and-desire to secure by Letters Patent is;

- 1. In a ball cock valve in which the valve I member opens against pressure and seats under pressure, a valve body-embodying a casing-section having a lateraladischarge port and a'downwardly projecting extension and a stand section receiving the extension of the casingsection, said extension having a valve seat on-itslower end, a stem working in and extending through the casing section and projecting into the stand section, a valve adjustably connected to-said stem for engagement with said; valve seat, a pair of standards carried by the. casing'section at one side of its upper end, a pair of lugs at the opposite side of said upper end of the casing section, a lever pivoted at. one end to said lugs and extending-through said stem an L-lever pivoted between the upper ends of said standards, a link connecting the shorter arm of said L-lever with the free end 1,047,:saa

pivotally connected at its upper end to the upper end of the long arm of said L-leve-r and adjustably connected at its lower end to said, long arm intermediate the ends of the latter, and a float connected to the upper end of said lever-arm.

2. In a ball cock valve, a valve body coniprising a casing section having a lateral dis charge port and provided with an extension having a valve seat, a stand section receiving the extension of the casing section and to which the casing section is secured, a valve stem extending through the casing section and having an opening theretnrough above the casing section, a valve on the stem withadjustably connected at its lower end to said longer arm intermediate the ends of the.

latter, and a float carried by said lewramn. 3. In a ball cock valve, a body comprising a casing section having a lateral discharge port and provided with an extension having a tapering valve seat on its lower end, a stand section receiving said extension and to which the casing section is secured, a valve stem extending through the casing section and provided with an opening above said section. a tapering valve on the stem within the stand section to engage said valve seat, a washer carried by the stem. to seat upon the upper end of the casing section around the valve stem when the stem is in its lowest position, a lever pivotally-mounted at one end on the upper end of the casing section at one side of the valve stem and extending through the opening in said stem, an L-lever pivotally-mounted on the casing section at the other side of said valve stem, adjustable connections between the other end of said lever and the shorter arm of the L-lever, a iever-arm pivotally connected at one end to the longer arm of said blower and at its other end adjustably connected to said longer arm, and a float carried by said leverarmi In testimony whereof We aflix our signatures in the presence of two witnesses.
