FLUSH TANK SUPPLY MECHANISM Filed Aug. 4, 1931 Patented Sept. 17, 1935 UN H'E'ED STATES aortas PATENT orgies 4 Claims.
This invention relates to flush tanks and more especially to an improved water supply control for such tanks.
One object of the invention is to provide a float operated valve mechanism' which will operate quietly, be eflicient in operation, and cheap in manufacture.
A further object is to provide a water supply control of the type secured to the tank bottom which will secure aeration of the water supply.
In the accompanying drawing, forming a part of this specification, there is shown, by way of illustration, a construction embodying the invention, which will now be described in detail and the features forming the invention then pointed out in the claims.
In the drawing:
Figure l is a transverse section through a flush tank showing my water supply control in side elevation;
Figure 2 is an enlarged side elevation of the water supply control with parts broken away to show its construction;
Figure 3 is an enlarged section with the valve partly open or partly closed as the case may be;
Figure 4 is a view similar to Figure 3 with the valve in full open position; and
Figure 5 is a section on line 5--5 of Figure 1.
Referring to the drawing, l designates an ordinary flush tank within which operates my water supply control, denoted generally as l I, the valve of which is operated through suitable mechanism by the usual float l2.
The body member I3 of my water supply control is flanged at E4 and provided with a downwardly extending screw threaded shank which passes through a hole in the bottom of tank I0 and is secured thereon by a nut l6 cooperating with flange M to clamp the body member l3 inposition on the tank ill, the usual water main connection (not shown) being secured on threaded shank i5 below the nut I8. Within the body I3 is formed a flange H which may be shapedto form the valve seat, but preferably I provide a valve seat I separate therefrom and cushioned thereon by a fibroid or other washer 2 as shown. This construction is desirable as the valve seat is readily accessible for repair or substitution and the closing movement of the valve well cushioned.
Above the internal valve seat flange ii the body member i3 is internally threaded to receive the externally threaded lower end of a tube or valve casing I8 provided with an annular row of ports 3 for supply of water to the tank l. V The upper end of the casing i8 is externally threaded to repin 2| on which is pivoted a lever 22 to the outer end of which is secured a ball arm 23 for the float or ball I 2. To the inner end of lever 22 is secured 5 a valve stem 24, preferably by pivot 25, which carries at its lower end a valve member denoted generally as 2'6, secured thereon by a pivot pin 217.
The lower end of the valve member 26 is formed to provide a supply valve 4 cooperating with valve 10 seat I, this valve being smaller in radius than the tube or valve casing l8 so that the water may flow upward thereabout when the supply valve 4 has been raised from its seat by the dropping of the float i2. Above the supply valve 4 and separated therefrom by a reduced neck 5 is a plunger 6 of such size as to neatly fit the tube or valve chamber is, the lower end of this plunger being so spaced above the supply valve 4 as to secure closure of the annular row of ports 3 by its lower edge in the closed position of the supply valve 4.
Usually the supply water would pass directly to the tank Ill through the annular row of ports 3, but I provide means for its aeration in its passage to' the tank l0. For this purpose the upper end of the body member I3 is internally recessed to provide a space outside the valve chamber it. Within this recess is secured, as by threading i, an aeration tube 8 which extends upwardly about the valve chamber i8. and forms therewith a passage 9 for delivery of the supply water to the top of the tank I 0. At its upper end the aeration tube 8 is provided with a fitting 28 suitably secured thereto, as by brazing, provided with a plurality of inwardly extending lugs 29, contacting with the valve chamber tube 8 to maintain the aeration tube 8 in properly spaced relation thereto. Bracket i9 is preferably provided with a downwardly extending flange 3t, spaced from and extending well below the upper end of the aeration tube 8 to provide a suitable spray head operating to break up the water flow for aeration thereof and direct the supply water downwardly into the tank Ill.
In general, the lowering and rising of the float operate the valve member 26 to fill the tank l0 and, when properly filled, shut oif the further supply of water thereto. In order to prevent chattering or whistling of the supply valve in its closing movement, as the supply valve l approaches its seat to shut off the supply water, the guide plunger and auxiliary valve 6 is simultaneously decreasing the eilective area of the annular row of ports 3.
What I claim is:--
1. In a float operated supply secured to a tank bottom, the combination with the supply control valve of a pipe receiving the supply water from said valve and extending above the maximum water level in the tank, and a spray head above the maximum water level in the tank receiving the supply water from said pipe for spraying the supply Water into said tank above the maximum water level in the tank, whereby the supply water always passes intosaid tank above the water level therein and aeration of the supply water secure-d.
2. In a float operated supply secured to a tank bottom, the combination of a valve casing extend ing upwardly above the maximum water level in the tank and having lateral discharge ports, a pipe enclosing said valve casing and having its open upper end located above the maximum water level in the tank, and a spray head carried by the upper end of the valve chamber above the maximum water level in the tank receiving the supply water from the open upper end of said pipe for spraying the supply water into said tank, whereby the supply water always passes into said tank above the water level therein and aeration of the supply water secured.
3. In a float operated supply secured to a tank bottom, the combination with a valve casing having lateral discharge ports near the bottom of the tank, and a float valve controlling said ports, of
a pipe enclosing the valve casing and extending 5 above the maximum water level in the tank, and
a spray head above the maximum water level in the tank receiving the supply water from said pipe for spraying the supply water into said tank, whereby the supply water always passes into said 10 tank above the water level therein and aeration of the supply water secured.
4. In a float operated supply secured to a tank bottom, the combination of a valve casing extending upwardly above the maximum water level in 15 the tank and having lateral discharge ports near the bottom of the tank, a float valve controlling said ports and closing the valve casing above the ports, a pipe enclosing the valve casing and extending above the maximum water level in the 20 tank, and a spray head above the maximum water level in the tank receiving the supply water from said pipe for spraying the supply water into said tank, whereby the supply water always passes into said tank above the water level therein and g5 aeration of the supply water secured.
