MANIFOLD VALVE Filed April 15, 1931 tions and to. provide suclrmeansin a particularly durable, easily controlled and. at .thesameltime;

Patented Apr. 23, 1935 NrrEo STA S- or-rice,

The objects of, the present invention are to provide simple and eifective meansv for valving.

and'manifolding' the pumps, stand-pipes and other apparatus. used in: rotary drillinggoperae relatively inexpensive form, suited'to all therequirements of the oil fields.

The attainment of such objects is effected by embodiment of the invention disclosed therein is a practical and commercial form, the structure may be modified in various ways, all within the true spirit and broad scope of, the invention- The single figure in the drawing is alongitudinal sectional View of the complete manifold, the

pipe connections thereto being broken away.

The body of the device consists of an intermediate trunk portion I, usually horizontally disposed and

valve chambers

2, 3, usually vertically disposed and secured to opposite ends of the trunk portion.

In the illustration, the main body or trunk portion is equipped with end flanges 4 and the two valve casings are constructed with lateral extensions 5, intermediate the ends of the same and provided with endflanges 6, detachably secured in the desired relations tothe end flanges of the trunk by the bolts 1.

The central manifold portion has a lateral extension 8, intermediate the ends of the-same,

arranged in downwardly extended relation in the illustration and flanged at 9 for couplingof piping Ill therewith.

The generally

cylindrical valve casings

2, 3, are shown as capped at the ends, the upper ends in the case illustrated, by covers ll, removably held by bolts [2 and as carrying adjustable glands l3, for packing the valve rods l4, extending through the same. The opposite or lower ends of these valvecasings are shown as formed with conical valve seats Hi to take the'lower conical ends of the valve plugs IS on the lower ends of the valve rods. The valve plugs may be made of hard rubber or fiber to slide freely in the valve casings and to make tight self-seating engagement with the valve seats and they are shown as removably secured on the lower reduced end portions ll of the valve rods by nuts l8, which clamp the plugs between washers I9, 20, against of thevalve plugs are indicated as cupped some what at 22, to seat the upper-washers To insure j smooth: travelcof. the valve plugs overthe? lateral. passesin'the sides of the valve:

" the shoulders 2t on: the rods. The upper ends; Y

casings,- said passes are-indicated as'bridged, by:

. or key, passed through an opening 25 in the valve rod and resting on top of the glandor valve 7 cap, as shown at the left in the drawing.

down to its seat by a set screw 25, having a pointed end engaging in a conical seat 2 in the enlarged end head portion 23 of the valve rod, said screw being carried at the end of a swinging yoke '29, hinging on pivot studs 39, projecting from opposite sides of the valve casings. These pivots for the swinging yokes are shown as arranged at right angles to the axis of the intermediate section of the manifold, so that when not in use, the yokes may swing inwardly down over and rest upon theintermediate portion of the manifold, as at the left in the figure, out of the way of other objects.

To lubricate the valve plugs and insure their free movement in the casings, grease or oil con nections may be provided at 3|, positioned adjacent the lower ends of the valve casings to discharge into the lubricating grooves 32, about the lower portions of the valve plugs.

The lower ends of the valve casings are illustrated as flanged at 33 for fastening of the pipe connections 34.

The pipe connections I0 and 34 with the intermediate trunk portion'and the end or valve casing portions of the manifold depend upon and will vary according to the uses to which the invention is put. For example, when used as a. manifold valve cetween pumps, the pipes 34 will lead from the two pumps and the pipe 5 I] will be connected with the stand-pipe.

When the device is used for manifolding standpipes, the end connections 34 will lead to the stand-pipes and the intermediate connection it] will come from the pump or pumps.

In the various uses of the invention, the two valves are separately controllable and either one or both may be opened or closed and'be secured in either relation. These valves furthermore are quickly shiftable from one position to the other liable to be injured or to get out of order. Either valve may be quickly seated after drawing out the pin which holds it from its seat, the valve stem may be rotated to clear the valve seat and firm sealing of the valve is readily effected by throwing the yoke up into position and then turning down the valve closing screw. The valve plugs are easily lubricated whenever required and such lubrication, in addition to assuring easy valve action, saves the valve plugs from undue wear. In addition to being of rugged design, the device is particularly compact for the service that it performs. It will be noted in particular, that the three lines of piping 34, I0, 34 are parallel and can be placed quite close together. The arrangement of the valve rods in substantial parallelism and both at the same side of the manifold body is a distinct advantage under circumstances which require prompt or immediate operation of both valves, as they are ends of the same and laterally opening side passages secured over the open ends of the manifold trunk, valves in the valve casings-for cooperation with the valve seats, valve rods operating through the ends of the valve casings for shifting the valves toward and away from the seats aforesaid, yokes mounted in swinging relation on the valve casings and screws carried by said yokes for engagement with the valve rods.

2. A manifold valve of the character disclosed, comprising a manifolding trunk open at opposite ends and having an intermediate flow passage, valve casings having ported side passages and secured with said passages in communication with the open ends of the trunk, said valve casings having cylindrical interiors into which A said side ports open and each having at one end 'of the same a tapered valve seat of approximately the full internal dimensions of the cylindrical interior, the opposite ends of said valve casings having upstanding yokes mounted thereon, cylindrical valve plugs shiftable in the cylindrical interiors of the valve casings and having tapered ends cooperable with the tapered valve seats, said cylindrical valve plugs being shiftable from said valve seats past said sideports in the valve casings, valve stems projecting from said valve plugs and screw connecting means between said upstanding yokes and the projecting portions of said valve stems.
