VALVE. APPLICATION FILED JAN. 9, I917.

3 woe/Mm UNITED STATES OWEN MARSHALL JONES, OF NEW YORK, N. Y.

VALVE.

Application filed January 9, 1917.

To all whom it may concern:

Be it known that I, OWEN MARSHALL JoNns, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Valves, of which the following is a specification accompanied by drawings.

The invention relates to improvements in valves, but in particular to improvements in valves commonly known as stop valves which are used for stopping or retarding the flow of fluids through ducts in which the valves are placed or to which the valves are connected, although the invention may be used in any connection in which it is found applicable.

The objects of the invention are to improve upon and simplify the construction of such valves and to increase their efficiency.

Other objects of the invention are to in sure tight seating valves.

Further objects of the invention are to supply valves which will become tighter the longer they are in use by having the valves self-grinding against the seats, thereby reducing to a minimum the possibility of leaks through the valves; and to these ends the invention consists of apparatus and devices for carrying out the above objects embodied in a valve having the features of construction, combinations of elements, and arrangement of parts, substantially as hereinafter fully described and claimed in this specification, and shown in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of one form of the apparatus embodying the invention.

Fig. 2 is a transverse section of the valve body through line A-B of Fig. 1.

Fig. 3 is a plan view ofa valve seat protecting plate.

Referring to the drawings, in Fig. 1, I have shown an illustrative embodiment of the invention. This view shows the valve open. 2 and 2 represent the body which may be of any suitable metal and which is in two sections properly held together, thus forming the body. 3 is the valve seat against which the valve disk 4: seats. 6 and 6 are ports through the valve disk which register respectively with the apertures 5 and 5 in the seat to allow flow of fluid through the valve. 7 is the inlet to the body. 8 is the outlet of the valve body. 9 is a Specification of Letters Patent.

Patented Dec. 28, 1920.

Serial No. 141,416.

stem extending from the valve disk with a transverse slot in the outer end. 2 1 is a barrel extending into the chamber of the valve body section 2. This barrel may be an integral part of the valve body section 2as shown or a separate barrel inserted through the wall of the body. This barrel protects the stems 10 and 9 from corroding or pitting elements. One end of the barrel 24E enters at the center portion of the valve seat 8 and this seat 3 is held in place by the overlapping of the flange on the larger end of the valve body section 2. 10 is a stem extending through the barrel 24: with a fiat reduced section at the inner end to be engaged by the slot in the stem 9. The stems 10 and 9 comprise the operating stem. 26 is an enlarged portion of the stem 10 and it is beveled on one side to fit in a corresponding bevel in the bottom of the barrel 21, thereby making a seat joint to prevent leakage around the stem 10 where it passes through the valve body. The enlarged portion 26 is for emergency only in case there might be slight leakage between the seat and the disk of the valve and into the barrel around the stem 9. 16 is a spring placed around the stem 10, one end bearing on the body 2* and the other end bearing against the collar 14, the collar being held in place on the stem 10 by the set screw 15, the collar being placed so that the spring is compressed, thus holding the beveled portion 26 against its seat. 13 is a handle acting as a r lever for revolving the valve disk.

The operation of the valve is as follows: The valve as shown is open and allows the fluid to pass through. To stop the flow of the fluid the lever 13 is revolved, which in turn revolves the stems 10 and 9 forming the operating stem, which revolves the disk 4 which moves the ports 6 and 6 out of register with the apertures 5 and 5*, thereby stopping the flow of the fluid. Naturally the reverse action of the lever again places the ports in register with the apertures. The fluid from the inlet side exerts a pressure on the back of the disk 4, thereby holding it tight against the seat 3 so that the fluid will not leak through the apertures in the seat 3. When the valve is in use, pressure is maintained on the back of the disk 4, so when the disk 4 is revolved to open the valve, it bears on the seat 3 and each time the valve is shut or opened the disk grinds on the seat, thus keeping a smooth seating surface at all times. The stems as shown are so arranged that there is a space for play between the bottom of the slot in the end of the stem 9 and the end of the flattened section of the stem 10 so that as the disk grinds or wears into the seat, the stem does not retard the disk 4 from always being seated against the seat 3.

I have also shown means for protecting that portion of the valve seat which is exposed through the port or ports of the valve disk when the valve is closed. 37 is a disk which forms the means for protecting that portion of the face of the valve seat which is exposed through the port or ports of the valve'disk'when the valve is closed. four lugs 38 on thedisk- 37 slide into the four slots 39 in the face of the flanged end of the valve body section 2 to hold the'disk 37 in place so that it will not revolve with the valve disk 36. The face of the valve disk 4 bears on the face of the seat disk 5. The side of the disk 37 which faces the valve disk 4 is faced off and bears on the back of the valve disk, 4, this back side of the valve disk also being'faced off. The Valve disk revolves and bears on the valve seat and the disk 37 bears on the back of the valve disk'4 by'pressure entering at the inlet end of the valve body. The lugs 38 loosely fit into the slots 39 so that the disk 37 will follow the valve .disk 4 when it wears either on its face or its back or wears into the valve seat, thereby scale, grit or other matter cannot enter the port of the valve disk when the valve is closed and attack or affect the faced surface of the valve seat.

The protecting plate 37 may also perform the functions of a valve seat in case of any ba'ck'pressure entering the valve through the discharge chamber. Under such circum'stances the back pressure will move the disk 4 together with the protecting plate 37 to the leftin- Fig. 1, and the plate 37 will then bear against shoulder 42 shown clearly in Fig. 2. Thereby'the protecting plate 37 will act as a valve seat, the disk being revolved against it. The lugs 38 engaging grooves 39 prevent the plate 37 from rotatingand' the jointed valve stem will permit'the disk 4 to move backward against plate 37. A

Obviously some features, parts, or con struction may be used without others and in combination with others and my invention may be embodied in widely varying forms.

Therefore, without limiting myself to the construction and arrangement and combinations of parts as shown'and described and Without enumerating equivalents; I claim and desire to obtain by Letters Patent the following:
