Application filed July 1, 1915. Serial No. 37, 525v To all whom it may concern:

Be it known that I, WILLIAM 'F. Ynnenns,

a citizen of the United States, residing at,

Huntington, in the county of Huntington and State of Indiana, have invented certain new and useful Improvements in Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in valves and more particularly to what are known as quick acting balance valves.

The object of the invention is to provide a valve of this character so constructed as to be perfectly balanced for preventing any possibility of pressure on either side from opening the valve and which is operated by a lever, thereby dispensing with the usual screw gear.

With the above and other objects in view, the invention consists of certain novel features of construction and in combination and arrangement of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 represents a side elevation of a valve constructed in accordance with this invention; Fig. 2 is a vertical section thereof; Fig. .3 is a horizontal section taken on the line 3-3 of F ig. 2; Fig. 4: is a similar view taken on the line 44 of Fig. 2' with the valve shown open; Fig. 5 is a similar view with the valve closed; Fig. 6 is a plan view with the valve removed; Fig. 7 is a detail perspective view of the lower end of the valve stem; Fig. 8 is a similar view with the valve in position thereon; and Fig- 9 is a detail perspective view of the valve detached showing the lower end thereof.

In the embodiment illustrated, a hollow cylindrical valve casing 1 is shown having alined coupling members 2 and 3 arranged to communicate with the casing and prefer ably cast integrally therewith and opening,

into said casing at oblique angles, the passages or conduits 4 and 5 which connect the openings in the couplings with the valve casing being arranged in planes substantially at right angles to each other, the opening 4 being in the form of a compound curve, and the opening 5 being obliquely disposed in relation to the coupling 2 with which it communicates. A socket 6 is arranged centrally in the bottom 7 of the valve casing and a concentric arcuate seat 8 is formed in said bottom for a purpose to be described.

A substantially cylindrical valve 9 fits within the cylindrical body portion of the casing land has anangular bore or channel 10 extending longitudinally therethrough and which is designed to receive a correspondingly shaped valve stem 15, said stem having its lower end rounded as shown at 16 to fit within the socket 6 of the casing which forms a bearing for said stem. The opening 10 which extends longitudinally through the valve 9 opens through one'side wall thereof as shown at 11 and said side wall through which this opening extends, is recessed as shown at 12, thereby providing two pairs 'of upper and lowerlugs 13 and 14 at the upper and lower ends of the valve, said recess forming a space for permitting the fluid controlled by the valve to pass when the valve is properly turned to bring said recess into communication with the openings it and 5 of the casing. This valve is provided on its lower face with an arcuate rib 9 which is adapted to project into the segmental groove 8 in the casing bottom and which is designed to abut against opposite ends of said groove for limiting the opening and closing movement of the valve to provide for said valve being opened and closed to its full extent only and to prevent its passing beyond these points. The outer face of the valve 9 adjacent one side of the recess 12 is cut away to form a pressure chamber 9 which is of a length equal to the distance between the inner faces of the upper and lower lugs 13 and 1.4.- adjacent which said chamber is formed. This chamber 9 tapers in a direction extending away from the recess 12, thus forming when the valve is in operative position within the casing a chamber for relieving the pressure. on thevalve and permitting.it to be distributed around the valve except that portion which covers the opening when the valve is closed.

The angular portion of the valve stem 15 which fitswithin the bore or channel 10 in the valve is designed to connect the valve with the stem and adapt it to be turned therewith when the stem is rotated. This stem 15 is also provided on its outer face of its upper and lower ends with laterally extending shoulders '17 and 18, the inner faces of which register with the inner faces of the lugs 13 and 14. The stem above the angular portion 15 is made round to adapt it to turn within a closure 19 which is shown in the form of a nut, the lower end of which is exteriorly threaded and screwed into an opening 1 in the top of the casing, said closure being provided with an annular flange 20 which abuts the casing around the opening 1. As shown, this nut has the usual angular portion arranged above the flange 20 designed to receive a wrench for removing and inserting the nut when desired. A cap' 21 surmounts the nut 19 and has a packin 21 arranged between it and the nut around the valve stem 15 to insure a fluid tight connection. The upper end of the valve stem is made angular as shown at to receive an operating handle 24: which may be held thereon in any suitable or desired manner, said handle operating as a lever for turning the valve stem to open and close the valve.

From the above description, it will be obvious that when the valve is inserted within the casing with the stem 15 arranged in operative position therein, it will be equally balanced so that pressure on either side thereof cannot open it, the operation of the valve being obtained by revolving it around its own center by means of its stem 15,,there being no screw or screw gear necessary to accomplish this purpose.

It is of course to be understood that this valve may be of any suitable or desired size and constructed of any suitable or desired material and that it may be used for any kind of fluid, gas, steam or air and will operate equally well when used in connection with any of them.

I claim as my invention:

1. In a valve, the combination .of a hollow cylindrical valve casing having alined coupling members with passages communieating with the casing at oblique angles and arranged substantially at right angles to each other, said casing having a socket arranged centrally in the bottom thereof and said bottom provided with a concentric arcuate groove, a cylindrical valve mounted to turn in said casing and having an angular channel extending longitudinally therethrough, a correspondingly shaped valve stem having its lower end rounded to fit in said socket, said valve channel opening through one wall of the valve, said wall being recessed on both sides of the opening and forming two pairs of longitudinally spaced lugs, an arcuate rib on the lower face of said valve positioned to enter the groove in the bottom of the casing, and being of less length than said groove, the ends thereof being designed to abut the ends of the groove to limit the turning movement of the valve in opposite directions, and means for relieving the pressure on the valve.

2. In a valve, the combination of a hollow cylindrical valve casing having alined coupling members with passages communicating with the casing at oblique angles and arranged substantially at right angles to each other, said casing having a socket arranged centrally in the bottom thereof and said bottom provided with a concentric a rcuate groove, a cylindrical valve mounted to turn in said casing and having an angular channel extending longitudinally there through, a correspondingly shaped valve stem having its lower end rounded to fit in said socket, said valve channel opening through one wall of the valve, said wall being recessed on both sides of the opening and forming two pairs of longitudinally spaced lugs, an arcuate rib on the lower face of said valve positioned to enter the groove in the bottom of the casing and being of less length than said groove, the ends thereof being designed to abut the ends of the groove to limit the turning movement of the valve in opposite directions, the outer face of said valve adjacent one side of the recess therein being cut away to form a pressure chamber tapering away from the recess, thereby forming in connection with the casing when the parts are assembled a chamber for relieving the pressure on the valve, permitting it to be distributed around the valve except at that portion which covers the opening when the valve is closed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witne'sses.

WILLIAM F. YERGENS.
