PUMPING JAR.

Application led July 18, 1922. Serial No.. 575,893. I s

To all whom it may concer/L.'

lle it known that l, VINCENT `Dn PAUL SPLANE, a citizen or' the United States, residing at ljaintsville, in the county ot Johnson and State of lentucky, have invented certain new and useful Improvements in Pumping' J ars, of which t-he following is a specilication.

My said invention hasfor its purpose to provide a coupling and jarring connection between the sliding or traveling' valve and the stationary valve ot' a pumpparticularly 'for oil wells, but adapted for any deep well., and it consists chiefly in improvements in the details of construction and arrai'igement of parts whereby many of the disadvantages in the use and operation of such Vpump heretofore experienced are overcome and a very convenient and efficient device for the purpose provided all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereot` and on which similar reference characters indicate similar parts,

Figure 1 is a sectional'view through an oil pump at the point of the location ot the working barrel,' showing the valves and pumping jar connection between them in elevation, and in the position they occupy when the upper or slidin valve is in the position of the limit o its up-stroke, and

Figure 2 a view on an enlarged scale showing the pumping jars separately, partly in section.

In said drawings the portion marked 10 presents the working barrel of a pump, 11

and 12 sections of the pump casing, 13 the stationary valve, 14 the sliding or traveling valve, 15 the lower jar or rein, and 16 the upper jar or working rein of the connection.

The working barrel 10, the case vsections 11 and 12, and the valves 13 and' 14 are in the main ot substantially a usual or any approved construction and arrangement. Packing rings or cups 20, usually of leather, are interposed between the lower edge of valve 14 and the upper edge of the socket 21 on the upper end of upper rein 16 and like cups 22 are interposed between the lower edge of the stationary valve 13 and the up-per edge ot a cage or crown 23. Socket 21 takes thc place and serves the purpose ot the crown or cage usually employed on the` lower end of the Sliding valve. By adjusting these crowns the packing is compressed more orless to secure the desired tit of thel valves."

The pumping jars comprise ytwo interlocked links made ot steel, or material that will stand any amountv of jarring service or strain without injury. The lower'jary 15 is formed with av screw-threaded boss or tang 17 on its lower end adapted to screw into' an internally screwthreaded collar on the upper end or' stationaryuvalve 13. The upper jar or working rein is Yformed with a tubular upper end on socket 21finternally screw-threaded and adapted toY screw on to a screw-threaded projecting boss' 24 on the lower end ot the sliding or. traveling valve 14. Said traveling valve 14 is attached to an operating rod 18 which is connected to the pumping jack in the usual manner. 'The links are formed with flat faces' atm25, 26, 27, 28 and 29 which contact at the limits of the movements of the links or jars. y, y

In assembling the parts for v operation the valves are properly connected by the pumping jarsl andgl as shown in Figure 1 and .hung to the operating rod 18 and lowered into the pump. The lower valve be.

cause of its tapered lower end readily enters the top of working barrel 10, the upper jar is loweredl until its lower end meets the lower inside surface 'of the lower pumping jar and its upper surface meets the upper end of said lower jar making a do-uble contact, then by a series of jarring strokes said valve-13 is driven to the lower end off the working barrel, its final` position being determinedl by measurement vor a shoulder 80, as will vbe readily understood. The pumpis then ready for operation and operates in the usual manner, the stroke of the 'traveling valve 18 beingvaried by the length of the links and theseare' made of different lengths to accommodate,l different conditions, the or# dinary or usual; strokebeing approximately 18 inches.

These pumping jars are made to screw directly on to the standard traveling and working valves or the type in common use, socket 21 serving the purpose ot the usual crown to tighten the cups to the diameter of the working barrel. The whole is low ered into the well at one time, the lower or stationary valve being first seated, when the pump is ready for operation.

It will be understood of course that these pumping j arsv are designed `\forfatt'aclnnent to any valve rods or sucker rods and to be inserted in any size tube. The normal operation of the pump isnotdifferent .from that'.

commonly in use. Vhen, however, the

valve becomes mudded up or the working" .isreturned vto its seat in the lower end of said .working barrel, as heretofore, and the pumping operation. may continue. Thus thisidiiicultymay be .overcome very quickly andthe necessityof pulling out the traveling valve-and then lowering a. grapple and removing thestationary valve and then reassembling the parts, one valve at a time as has beenl heretofore the custom, is avoided.- Another advantage in the. use of jars of this .constructionis found when it becomes necessary to :pull the valves out of thewellas when thepacking cups are out or wor-nbysandr Bymy arrangement botlrthe. traveling. and stationary valve may,b'el.removed.by one operation and the cups. adjusted or replacedA by new ones, whereas .by theusnal .arrangement it is necessaryto pullthe traveling. valve and remove ,thefrods, then vrun the vrods back into the wellfwith `a grapple to pullout the standingvalve..v

Theseand ,otherl `obvious advantages result .from-the employment of my pumping jars, allas .will be readily understood.

Having thus fully described my said invention, what l claim asnew and desire to secureloyV 'Letters Patent, .is

l. A pump comprising. a working. barrel, a stationary valve, a traveling valve and interlocked pumping` jars connectingv said twovalves, one being connected to the upper end ofthe stationary valve and the other toi .the flower 'endl of 4`the sliding. or working valve, saidfpumpingjarsbeing of uniform length-'whereby lwhen used for jarring purposes a double Contact is made at the closing of the jars, substantially as set forth.

2'. A pump comprising a casing having a working barrel as a section thereof, a stationary valve'forservicel in the lower end of said working barrel, a traveling valve, and pumping jars connecting said valves, the upper ar being adapted to screw on to a screw-threaded boss or collar on the lower end of the traveling valve and the lower jar being adapted to screw into a screw-threaded collar on the upper endof a lower jar, said jars being of uniform length, substantially as set forth.

3. A pump comprising a working barrel, a stationary valve, a traveling valve, and interlocked link-like pumping 'jars connecting said two valves, oneof saidpumping jars being connected withwthe upper'end of the stationary valve andthe other with the lower endof the sliding or working valve, said valves being provided with packing and the upper valve having said packing interposed between the lower. edge of the valve casing. and vthe'upperedge of a socket formed 'inthe' upperend 'of the upper rein ofthe pumping jars, substantially as set forth'.

4. A pumpcomprising a working barrel, a stationaryl valve, a traveling valve, and interlocked link-like pumping vjarsl connecting said valves one of said. link-like jars being formed with a fiat faceA for receiving a blow from the othersaid jar, substantially as set forth.

5.y A` pumpcomprising a working barrel, a stationaryY valve, a traveling valve, interlc-ked tpumpingjars.connecting said two valves, one to the upper. end of the stationary valve and rthe'vother to thelower end of the workingv valve," saidljars :being'of uniform lengthand'formed with kflat contactingvfaces adapted to meet at the extremes ofV the movements of the sliding valve, substantially as set forth.

ln witness whereof, I have hereunto set my hand 'and 'seal at Paintsville, Kentucky this 19th dayof June, l;- D. nineteen'hundred and twenty-two.-
