2 Claims.

My. invention relates to pump manifolds and their valves; and more particularly to those adapted for use in the rotary drilling of oil and gas wells.

This is a substitute application for the one made by applicant in the United States Patent Oflice filed on October 27, 1928, under Serial Number 315,376, for patent for Improvement in pump manifold ball valve.

Except for the integral downturned ends of the manifold body, the subject matterof the present application will be found in the application made by applicant in the United States Patent Ofdce filed on December 14, 1927, under Serial Number 239,851, for patent for Improvement in slush pump manifold under which application as of date of April 30, 1928, by ofiicial communication a division was required as between claims 1 and 3 thereof for a plug valve, and claims 2 and 4 thereof for a-ball valve. V

The objects of my invention are to produce a device of the class described which will be new, novel, inexpensive, practical, efficient and of utility; which will automaticaly permit of its shifting from the use of one pump to another in oil and gas well drilling with a rotary drilling out-fit and in well and other pumping operations and in boiler feed pumps and the like; which will prevent the necessity of the use of two or more expensive valves in connection with the drilling out-flts above described; which will be strong, durable and will not easily get out of order; which will prevent the frequent caving in of oil and gas wells by providing for the possibility of a continuous flow of the drilling fluid into the well at all times for drilling use; which into either valve seat; which eliminates the large number of parts required in normal slush pump manifolds; which can be seated easily, quickly and automatically in a firm position to close either source of fluid desired to be guided in a given direction; which can be used on any alternating or intermittently acting double pump such as boiler feed pumps and oil and gas well pumps and mud pumps where one discharge line is used; which will be cheap in construction and in manufacture.

With these and other objects in view as will more fully appear my invention consists in the construction, novel features, and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in the accompanying one-sheet drawing, of which,

Figure 1 is an elevational view of the device in connection with two pumping lines; 1

Fig. 2 is a vertical sectional view of the device showing the ball valve; and

Fig. 31s a perspective view of one of the removable valve seats.

Like characters of reference designate parts in all the figures.

It is understood that various changes inthe form, proportion, size, shape, weight and other details of construction, within the scope of myinvention may be resorted to Without departing from the spirit or broad principle of my invenlike tages thereof; and it is understood that the drawings are to beinterpreted as being illustrative and not restrictive.

In drilling with a rotary rig it is necessary to provide two pumps in order to provide a continuous and uninterrupted flow of fluid under pressure, The drillinglluid is forced'through pipes and hose into the hole through a rotating shaft, to the rotating drill at the bottom of the ing whence it and the loose material formed thereby is carried to the surface and emptied into a basin or pond. The extraneous matter settles from the fluid, and it is again ready for another cycle of operation. If an interruption occurs in this process and the pressure of the drilling fluid is not maintained, the well or hole is exposed to the danger of caving in and closing up the hole. All of these possibilities and other disadvantages are obviated by my invention.

I bring about these advantages by providing: a longitudinal cylindrical body 1 having an upstanding portion 2 forming a union 3 with a stand-pipe outlet 4 having a bore 5 therein; on body 1 are provided integral turned down ends 6 and '7 having flanged unions 8 and 9. These are adapted for connecting with pipes 10 and 11 and lines from

pumps

12 and 13. I also provide

v valve seats

14 and 15 each having rim shoulders 16 with a plurality of perforations 17. Said shoulders 16 are adapted for seating between flanges 8 and 9 and similar flanges l8 and 19 on said pipes 10 and 11. I alined with similar perforations in said

flanges

8 and 9 and 18 and 19 and are held securely together by suitable bolts and nuts or other suitable holding means (not shown). Said

valve seats

14 and 15 are bevelled from their tops 20 towards llo tion and without sacrificing any of the advan-.

8 well and thence out at the drill point into the cas- Said perforations 1'7 are ,195

their bottoms 21 of suitable size for seating the ball valve 22.

In operation when my device is attached to the pipes 10 and 11 in working position and to the stand-pipe4, one of the pumps is started. For use in oil and gas well drilling this usually has a pressure of approximately 500 pounds.

The drilling fluid coming into the body 1 will immediately by such force be driven to the opposite end of the body and the ball valve 22 will be carried to the valve seat opposite from the end from which the fluid enters and there will be seated. This will close the port thereunder. The fluid will then be forced out at the stand-pipe outlet 4. If the pump then in use becomes disabled, or is shut off for any reason, the other pump is then turned on. This will force the ball valve 22 away from its seat and will carry it to the opposite side of the body 1 and into the lower end thereof where it will be seated and lodged in the valve seat. The drilling fluid will then be forced out the stand-pipe outlet 4 and thence into the well, rotary shaft, etc., and out again as above described. The ball valve 22 is of such size that it will not in any event be forced out of the bore 5 and into the stand-pipe outlet 4. However, this is not necessary as the fluid forced from the pump put in operation will drive the ball valve 22 to the other and lower end of the body 1 since there is no force being exerted from the other pump and pipe.

It will'be observed by those familiar with the art to which my invention pertains that after the installation of my device the turning on of one of the pumps makes the working of the device automatic. Also that in case the valve seats becomeworn, byloosening the fastenings for

flanges

8 and 9 and 18 and 19 and separating the flanges, the valve seats 14 can easily be taken out and easily replaced by others, without interference with the drilling operation except for a. very limited period of time. It will also be understood said ball valve may be made of a suitably hard substance such as steel, fibre, rubber, and the like.

Having thus described my invention what is claimed and desired to be secured by Letters Patent is:

1. A pump manifold ball valve of the character disclosed and comprising a horizontally extending cylindrical manifold body having downturned ends with horizontal flanges for the fastening of lines leading from two pumps and having an upper intermediate flanged outlet for the connection of a stand pipe, removable valve seats having horizontal flanges engaged with the horizontal end flanges of the manifold body and having vertically extending bevelled bores entered in the downturned end portions of the manifold body with the larger ends uppermost and opening into the body and the smaller ends at the bottom and opening into the pump lines and a ball valve of a size to interchangeably fit in the bevelled bores of the two valve seats and to freely roll along the horizontal portion of the manifold body to automatically clear itself before dropping into one or the other of such valve seats.

2. A pump manifold ball valve of the character disclosed and comprising a manifold body having an intermediate portion with an upwardly extending flanged outlet and having downwardly extending end portions with flanges for the fastening of flanged lines leading from two pumps, downwardly tapered conical valve seats, removably seated in said downwardly extending end portions of the manifold body and detachable from the manifold body independently of the flange connections between the pump lines and the manifold and a ball valve automatically shiftable by pressure fluid from one end to the other end of the manifold and from the valve seat at one end across the intermediate portion to the valve seat at the opposite end and removably retained in such relation by said detachable valve seats.
