EDW M. BEEBE, OF CUSHING, OKL "x SLUSH-LPUMP MANIFOLD.
Application filed April 14, 1928. Serial No. 270,080.
My invention relates to improvement in slush pump manifolds, particularly applicable for use in drilling oil and gas wells with what is known as rotary drills.
5 The objects of my invention are to produce a device of the class described which will be new, simple, novel, inexpensive, practical,
efiicient and of utility; which will automatically permit the shifting of one pump to another in. the job in drilling with a rotary drillingoutfit; which will prevent the necessity of the use of two .or more expensive valves in connection with the drilling of such drilling outfit; which will be stron durable and which will not easily get cgnt 0 order; which tached and changed; which will eliminate the use of gates now required in such drilling; which will include a double valve having both ends the same edge of which is adapted to fit into the valve seat another valve is introduced into the end adjacent the respective seat therefor; which eliminates a large number of parts required in former slush pump manifolds; which eliminates the valve seat shown in a separate piece at Figure 3 of the drawing in my former application for patent for improvement in slush manifolds, filed December 14, 1927 under Serial Number 239,- 851; which eliminates the several separate parts of the double valve shown in Fig. 4 of said application just described making in stead of them the double valve of one piece of metal each end of which is adapted to receive there surrounding a packing substance 'for contacting the respective valve seats; which rovide standard ipe threading for the en s of the flanges or connection for other parts of the mechanism.
My invention consists of the novel features, construction and combination of parts hereinafter more, fully described, illustrated in the accompanying onessheet drawing, and pointed out in the appended claims; it being understood, however, that various changes [may be made in the form, proportion, size, shape, weight and minor details of construcvtion, within the scope of my invention with-v out departing from the spirit and principle vantages thereof. 1

used, one of the essentials is a continuous and interrupted flow of water under pressure. TlllS water is forced through the pipe and In the drilling of a well by a rotary drillmg outfit where two alternating pumps are hose down the well throu' 'h a rotating-shaft a to the rotating drill an out at the drill point into the casing whence it and the loose material produced by the drillin is carried to the surface and emptied into 51c basin or pond. The sediment settles, the water clears and is again ready for use in another cycle .of operation. If an interruption in this process occurs the well or hole is exposed to much danger from caving in, closing up, and the like. All of these. and other disadvantages are obviated by my invention. .011 December 14, 1927, under Serial Number 239,- 851, I filed an application for patent under an improvement in slush pump manifolds. I desire this application to be considered as an improvement over and in connection with said application. I claim an improvement over said former application in that the valve seats contain a less number of parts and will cost lessin manufacture and installation and take less time in installing and removing and the machined seat being in one piece Wlll be stronger and less liable to get out of order.
I also claim the double valve in this applithat the hydraulic packing is better posi- 'tioned, more substantial, more lasting and much less liable to become loose and removed and get out of order.
I desire to have the drawing and these specifications to be considered as illustrative I provide a longitudinal cylindrical body and not restrictive only. One embodiment of my invention may be described as follows 1 having a central upstanding flange 2 being L-shaped, having a central bore 3 and having an L-shaped flanged member 4 thereabove for forming with said first flange 2 a union. Both of said members having conjugate perforations 5 and 6 and being adapted to be securely held together by bolts and nuts 7 and 8; said upper flange member 4 having a central bore 9 with its upper portion having standard threads 10 for seating a stand-pipe 11 thereabove. On each end of body member 1 is provided an L-shaped union 12, 13, being adapted to fit L-shaped flanged valve seat members 14 and 15, said flanged member 12 and said valve seat member 14 having conjugate perforations 16 and 17 therein for securely holding together by bolts and nuts 18 and 19 and said flanged member 13 and said valve seat member 15 having conjugate perforations 20 and 21' therein for securely holding them together by bolts and nuts 22 and 23. I prefer to have between said flanged portions 12 and 14, and said portions 13 and 15 cylindrical shoulders 24 and 25 for more securely holding saidmembers together.
I also prefer to have similar shoulders 24" and 25? between flanged members 2 and 4.
Said flanged valve seats 14 and 15 are preferably machined on their inside surfaces and taper from points 26 adjacent said shoulders 24 and 25 diminishing outwardlyrespectively therefrom to points 27, from said points 27 outwardly to their respective ends 28 and 29 they are standardly threaded 30 and 31. To these threaded end portions. are connected pipes 32 and 33 connecting with slush pumps .34 and 35.
I also provide a double plug valve 36 sub- I I stantially barrel-shaped, being formed of one 40 piece of metal, preferably of steel The end portions 37 and 38 from points 39 and 40 from approximately the distance of one third of thelength of said member from each end to points 42 and 43 are tapered 44 and 45 diminishing from said points 39 and 40 respectively to points 42 and 43. Intermediate said points 39 and 42 and 40 and 43 I provide channels 46 and 47 encircling said barrelshaped member the inner portions of said channels 46 and 47 being hollowed out internallyon each side'from their respective peripheries as indicated by dotted-1n portions 48, 49 and 50, 51 for receiving and securely holding hydraulic packings 52 and 53. I also provide frustum-shaped hydraulic packings 52 and 53 for insertion within said channels 46 and 47 the wider dimension 54 thereof being adapted tobe inserted against the inner surfaces of said channels, and are intended to entirely fill said channels including their wider dimensions as shown by said dotted-in portions 48, 49 and 50, 51. Said hydraulic packing members 52 and 53 are intended to extend slightly beyond the tapered surfaces 44 and 45 but not as far as points 39 and 40 thrown into operation.
on said surfaces. Any suitable hydraulic packing may be used. But I prefer to use a good grade of packing for such purpose.
In operation when my device is attached to the pipe in working position, and to the stand pipe, the pump is started. This has approximately a pressure of 500 pounds, or more. The water entering the body 1 of the device will immediately drive the valve 36 to the opposite end of the body 1 from that in which the water enters and the valve 36 will immediately close such opposite end; the hydraulic packing 52 and 53 around such end will be forced against the machined inside surface of the valve seat thereby closing the port adjacent thereto against egress of water, and the like, through opening 3 in L-shaped flange 2 into stand-pipe 11, and thence into the hose, well, rotating shaft, etc, and out again. If the pump being used becomes disabled, or other interruption occurs, the other pump is then I The plug valve will then be driven to the opposite end ofgthe device where it will be lodged in the tapered portion of the opposite valve seat. The flow of the water outwardly therethrough will be stopped and the liquid will then be forced through the same opening 3 thence into the stand pi pe, hose, well, rotating shaft, etc. and
ing thereof will be automatic. Also in case of the wearing of the hydraulic packing or of and the water will be forced the valve seats by loosening the bolts and nuts I and removing the valve seats new valve seats.
can be supplied and installed easily and new hydraulic packing can be easily and quickly installed on the double plug valve, bothof which processes will be cheaply and quickly done without interferring'with the operation of the drilling for any considerable length of time.
