Application mea November 8,1910. seal No. 591,362.

To all whom t may concern.' Be it known that I, WILLIAM L. PARKIN- soN, a 4citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new land useful Improvements in Valves; and I over the end of the inlet pipe to s top the tlow of water therefrom.`

A further object isto provide means for lowering the valve in position over the end of the inlet pipe and at the same time direct apressure thereon. v A further object is to provide a bushing to reduce the pressure of the water when entering the tank. A further object is to so arrange the valve that the pressure of the water will be directed against the seat thereof, and, a further `object is to provide`a connection between the inlet valve and theutlush valve of the tank. Other objects and advantages will be hereinafter set forth and pointed out in the specification.

ln the accompanying drawings, which form a part of this application, Figure 1 is ari-elevation partly in section of my improved valve. vF ig. 2 is a plan view of the inlet pipe, and, Fig. 3 is a bottom plan view 4ci" the valve.

Referring to the drawings, in which simi lar reference numerals designate correspending parts throughout the several views, 1 indicates the wall of the tank, which in this instance is 'used for closet purposes, and 2 indicates a connection which projects. through the bottom of the tank and terminates in a head 3 at its upper end. while the lower end thereof is at 1 tached to the usual form of water supply pipe (not shown). l

The upper end of connection terminates in a nozzle 4, which is preferably tapered and in order toreduce the pressure of the water passing through 'the connection, a tapered bushing 5, having its discharging end reduced in the passage through the size, is'introduced into the nozzle and preterably projects beyond the end ot thenozzle, although it may he tlush theregwith `itso desired. rlhe object in projecting the end of the bushing beyond the nozzle is that the vbushing may be reamed out or made larger in cases of low pressure andin some cases the bushing may be entirely dispensed with.

Extending upwardly from the head 3 is a standard G, to which is pivot'ed the arm Tof a vah'e 8, said valve being adapted to swing over the end of the nozzle. The lower tace4 of the valve is provided with a cavity or seat 9, in which is preferably placed suitable packing 10, preferably of leather, so

that when the valve is seated over the end 1of' the bushing or nozzle a complete seal will be formed.

1n order to control the movement of the valve in accordance with the amount of water in the tank, a lever 11 is pivotally connected to the upper end of the standard 6 and the terminal 12 thereof projected over the valve and is connected to the valve by a link 13 sothat when the lever is swung upwardly or downwardly the valve will be accordingly lowered or raised.

The various pivotal connections between the several parts are formed by means of Cotter pins or split keys 14, which are preferably formed of brass to prevent corroding or rusting of the same and by using the cotter pins instead of bolts or rivets, the various parts of the valve construct-ion can, be quickly taken down or assembled.'

ln order to prevent' leakage around the connection 2 a gasket or similar device 15 is placed between the head and the bottom of the tank and the head is drawn securely against the gasket by threading the exterior of' the connection and introducing a nut 1G thereon, which nut jams against the bottom of the tank.

When the valve 8 is lifted from its seat the cavity rests at an angle to the path of the flowing water and in view of the force of the water when entering the tank, any sand, sediment or other obstruction adhering to the packing or wall of the cavity will be removed. It will likewise be seen that in view of the cup shape of the cavity the water will'be thrown downwardly toward the head after engaging the cavity. In order to permit a certain amount of water to escape from the tank while the tank is being refilled, the head 3 is provided with a ylikewise be seen that thewater will be directed into the open arm of the port under pressure in view of the angle of the valve proper when raised, as the water on leaving,- the cavity in the valve will be directed toward the port. lit will likewise be seen that this device can be very cheaply con- Sl'rneted and the parts thereof readily assembled and applied to use, and, it will likewise be seen that the valve will beV thoroughly cleaned of any sediment by the force of the. water when entering the tank and that-all of the wearing parte may be easily laken apart and renewed when necessary.

What l claim ie:

ln a tank valve construction the combination with a, connection having an opening' therethrough, a head at the upper end of Jthe connection and a standard at one Side and integral with said head, said head hav ing -a siilbstantially U-shaped port formed therein in the side thereof opposite the Stande rd, an overflow pipe leading from one stein of said port While the other end of said port is open, said pipe being opposite to and parallel with the standard, a valve pivoted to the lower end of said standard and liavinfby ay cavity adapted to lit over the upper end of said connection, a lever pivoted to the upper end of said standard, a link connecting the inner end of 'said lever to he top of said valve, said link being positioncd and working between the standard and overflow pipe, and a conical bushing in said connection to reduce the pressure of the water pas-sing therethrou h.

l'n testimony whereof have signed my naine lo this specification in the presence olf two subscribing witnesses.
