I VALVE FOR WELL PUMP .RODS

Filed Feb. l, 1938 Pulled .lu- 13, 1939 UNITED STATES PATENT OFFICE VALVE FOR WELL PUli RODS William John Wranosky, Freer, Tex. .Annlieation February 1,` 1938,` Serial No. 188,161

1 claim. (c1. 10s-zes) The present invention relates to valves for the pump rods of oil wells and the like and has for its primary object to provide an automatic pressure actuated valve carried by the pump rod above the piston or plunger and arranged for opening movement upon the upstroke of the plunger and embodying means for automatically closing the valve upon the down stroke of the plunger to relieve the plunger of the -weight of the fluid in the tube above the valve during said downstroke.

An object of the present invention is to provide a valve structure of this character of simple and practical construction, which is eillcient and reliable in performance, relativelyinexpensive to manufacture and install in operative position within the well casing and otherwise -well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference beinghad to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout and in which Figure 1 is a fragmentary vertical sectional view through a pump tubing showing the valve in position therein, a

Figure 2 is a transverse sectional view taken substantially on the line 2 2. of vFigure l and' Figure 3 is a side elevational view of the valve and sleeve mounted upon the pump rod.

Referring now to the drawing in detail. the numeral 5 designates a well tubing within which the pump rod i' is mounted for operation in the of which fluid is adapted to'pass upwardlythrough the cage to the upper portion of the To the lower end of the .cage 8 threadedly Vsecuredavalvebodyllhavingaborellextending therethrou8li, the upper end of said bore being of increased diameter to provide a shoulder I3 upon-which a valve seat'll is iositioned. A substantially conical valve Ii is invertedly arranged and threadedlysecured to the lower end lofthesleevelfor cooperationwlththevalve usual manner, the lower end of the pump rodV seat Il to close passage through the bore I2, said' valve being provided with a central opening I6 through which the rod i is slidably inserted. The upper portion of the valve is provided with an annular channel il which is seated the lower end of a coil spring i8, the upper end of said spring bearing against the top of the cage to yieldably urge the valve downwardly into engagement with the seat Il.

The upper edge of the sleeve 'i is bevelled as at l! to provide a knife like edge 2U which bears against the rod 6 to scrape sand from the rod during the reciprocating movement thereof. The lower portion of the valve body Il is provided with annular grooves 2l for receiving packing rings 22 in order to anchor the'cage in the tubing.

In the operation of the device upon the upstroke of the plunger attached to the lower end of the rod 6 the valve i5 will be forced open to f allow the fluid to pass upwardly through the cage to the upper portion of the tubing 5 and upon the downstroke of the piston and rod 6 the spring Il will serve to close the valve, and the iluid accordingly will be retained above the plunger in the upper portion of the tubing.

It is believed the details of construction' and manner oi' operation of the device will be readily understood from the foregoing without further detailed explanation.

What is claimed is: y

A vvalve for the pump rod of an oil well comprising a sleeve having a working t upon said Y rod, a valve cage having an opening in its upper portionA slidably receiving said sleeve, said cage being spaced from the sleeve and having openings for the passage of iluid through the cager,a valve body threadedly secured to the lower end of said cage, packing means surrounding the valve body and engaging the tubing of the well, a' valve seat carried by said body, a valve threadedly secured to the lower end of said sleeve and arranged in cooperating engagement with said valve seat, said valve having an opening for the passage ofthe rod, said valve being responsive to pressure below the valvefor opening movement, a spring surrolmding the sleeve and having one end engaging une valve and its other end engaging the top of the cage for holding the valve upon the l seatandtheupperendofthesleevebeingbeveled for scraping foreignmatterfrom thatpartofthe rod'whichit wurm JOHN wamosxr.
