VALVE Filed May 5, 1952 Eggi Patented July 3, 1934 UNITED STATES VALVE Harry S. Steen, Chicago, Ill., assignor to Chicago Faucet Company, Chicago, Ill., a corporation of Illinois Application May 5, 1932, Serial No. 609,527

5 Claims.

This invention relates to improvements in valves and, more especially, a water valve adapted for use in controlling the supply to a Water closet tank, such valves being commonly known as ball cocks.

Among the features of my invention is the provision of such a valve adapted to be pontrolled by a float, which will close relatively rapidly as the water reaches the required height. By this construction, the tank is .filled rapidly after fiushr ing and again ready for use.

Anotherfeature of my invention is the prevision of valve mechanism that is efficient and rapid in operation and so made that the direction of operation of the valve can be easily reversed. My improved valve mechanism is also removable as a unit to permit inspection, repair and replacement.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features 'of my invention shown in the accompany ng drawing Figure 1 is a vertical sectional view taken through a tank showing my improved valve installed therein; Fig. 2 is a vertical sectional view of the valve; Fig. 3 is a view similar to Fig. 2

showing the valve closed; Fig. 4 is a similar View showing the valve open; and Fig. 5 isa view in perspective and partly in section of the sleeve and :valve stem.

As shown in the drawing, indicates a tank, for example, a water closet supply or flush tank; 11, the water therein; 12, the ball cock controlled by the float 13; 14, the usual overflow; 15, the refill pipe; and 16, the outlet or flush pipe con- .trolled by the rubber ball 17.

My invention relates to the construction of the valve 12 and the same will now be described in detail. Numeral 18 indicates a substantially spherical casing with the inlet opening 19 and outlet 20 leading to the inlet and outlet chambers '19 and 20 respectively, separated by the partition or diaphragm 21 with the opening 22 therein. At one side, opposite the hole 22, the casing 18 is provided with an exteriorly threaded cylindrical extension 18 adapted to receive the valve mechanism to be hereinafter described.

The valve mechanism includes a cylindrical sleeve 23 with a removable valve seat 24 at the inner end. 25, 25 indicate holes for the passage of Water, as indicated by the arrows.

Numeral 26 indicates a cap adapted to be screwed onto the extension 18 to cover the same and hold the sleeve and cap therefor in place. 27

Longitudinal movement of the stem 27 outwardly causes the valve disc 28 to rest on the seat 24 to close the valve and longitudinal movement in the opposite direction opens the valve. Co.-operating cam surfaces are provided on the sleeve 23 and the stem 27.whereby rotation of the ,stem in one direction will close the valve. There is also provided a cam surface on the cap oo-operating with a cam surface on the stem whereby rotation of the stem in the reverse direction will open the valve. There is also provided a cap 31 for the sleeve 23. Rotational adjustment of this cap grill reverse the valve action, as will be deseribed. As here shown, the cam surfaces on the stern and sieeve'ne so arranged that rotation of the stern in either direction with the cap removed will close the'valvi. The cam surface on the gap when the same is in place cooperates with a cam surface on the stem to prevent closing of the Valve by rotation of the stem in one direction. The desired direction of rotation may be obtained by adjusting the p0;- sition of the cap. The cam' surfaces on the sleeve 23, stem 27 and cap 31 above referred to are double. That is, each carries twosuch cam surfaces diametrically arranged. It Will be necessary to describe but one in order to show the action in the valve. The cam surfaces on the sleeve 23 are indicated by 32. These comprise two V-shaped members. The stem 27 carries a cylindrical enlargement 33 provided with V-shaped notches defined by the cam surfaces 34. The V-shaped members formed by the surfaces 32 are indicated by 32 The cap 31 is provided with cam surfaces on V- shaped members similar to the cam surfaces 32 on the sleeve. And the member 33 on the stem carries v shaped notches with the cam surfaces 36 adapted to co-operate with the cam surfaces 35 on the cap. With the cap removed, it will be seen that the surfaces 34 on the stem will ride on the surface 32 on the sleeve so that rotation of the stem in either direction will close the valve. The cap may be adjusted, however, so that the cam surfaces 35 will engage the surfaces 36 so that rotation of the sleeve in one direction will operate to open the valve. When so adjusted, the cam surfaces 35 on the cap will also co-operate with the cam surfaces 36 on the stem to permit rotation of the stem in one direction to close the valve and prevent rotation of the stem in the opposite direction to close the valve.

One of the V-shaped members 37 on the cap is provided with a pin 38 adapted to be engaged in either one of the two slots 39 or 39 n the edge of the sleeve 23. When the pin 38 is in the slot 39, as shown in the drawing, rotation of the stem 27 in a clockwise direction to close the valve is permitted; whereas rotation of the stem in a counterclockwise direction to close the valve is prevented. When in this position, rotation of the stem in a counterclockwise direction operates to open the valve. When the pin 38 is placed in the slot 39 the action of the valve is reversed. That is, counterclockwise rotation of the stem will close the valve and clockwise rotation will open it.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in View of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

1. Valve mechanism of the character described, including; a sleeve with a valve seat at one end; a cap for the sleeve at the other end; a valve stem rotatably mounted in the sleeve and extending through the cap; a valve disc on the stem co-operating with the seat by longitudinal movement of the stem to open or close the valve; co-operating cam surfaces on the sleeve and stem whereby rotation of the stem in one direction will close the valve; a cam surface on the cap co-operating with a cam surface on the stem, whereby rotation of the stem in the reverse direction will open the valve; and means by which rotational adjustment of the cap will reverse the valve action.

2. Valve mechanism of the character described, including; a sleeve with a valve seat at one end; a cap for the sleeve at the other end; a valve stem rotatably mounted in the sleeve and extending through the cap; a valve disc on the stem co-operating with the seat by longitudinal movement of the stem to open or close the valve; 00- operating cam surfaces on the sleeve and stem whereby rotation of the stem in either direction will tend to close the valve; a cam surface on the cap co-operating with a cam surface on the stem to prevent closing of the valve by rotation of the stem in one direction; and means by which rotational adjustment of the cap will reverse the valve action.
