UNITED STATES JEREMIAH J. FITZPATRICK, OF TULSA, OKLAHOMA.

TRAVELING VALVE FOR WORKING BARRELS FOR OIL-WELL PUMPS.

Application filed May 1,

T 0 all 1/) 710m it may concern Be it known that JEREMIAH J. Frrz- PATRICK, a citizen of the United States, residing at 1123 So. Trenton Street, Tulsa, in the county of Tulsa and State of Oklahoma, has invented certain new and useful Improvements in Traveling Valves for Working Barrels for Oil-Well Pumps, of which the following is a specification.

This invention relates particularly to the traveling valve for the working barrel in oil well pumps.

An object of the invention is the provision o-f a traveling valve that will permit a more rapid stroke than at present attained and consequently raise a larger amount of oil.

A further object is to provid metallic cups for the traveling valve that are etlicient and practical, and to minimize the necessity of frequently changing the cups with the consequent expense and loss of time.

A further object is attained by providing a traveling valve with metallic cups so beveled on lower portion that it will enter the working barrel easily and without catchlng.

A further object attained is the increased space for the oil flow through the interior of the traveling valve.

Further objects and advantages will be apparent in the course of the following explanation.

In the accompanying drawings, I have shown one embodiment of the invention. In this showing:

Figure 1, vertical View.

Figure 2, vertical cross sectional view of shank.

Figure 3 shows views of piston ring, cross sectional and perspective.

Figure 4 shows piston ring positioning member.

Figure 5 spacer.

Figure 6 is a collar or washer.

Referring to the drawings Figure 1 shows the assembled traveling valve which forms the subject matter of the present invention. It is well known that in pumping oil or other fluid from driven wells a working barrel is immersed in the fluid at the bottom of the well to lift the fluid through the connected tubing to the surface. These working barrels as they are almost univershows positioning member 1923. Serial No. 636,008.

sally used are of similar construction, havmg a standing valve at the bottom through which the fluid enters the barrel, which is connected at the top to the well tubing, through which the sucker rods operate to raise and lower the travelin valve. As the working barrels are in suc common use, and form no part of my invention, which can be used in any and all of them, I deemed it not essential to illustrate them and have omitted same from the drawings. Figure 2 shows the cylindrical shank, screw threaded at the top and bottom for the attachment of the crowns as shown in Figure 1. Figur 4 represents the collar through which the shank slidably passes and adapted to carry the rings in pairs, one above and the other below the shoulder. These rings are shown in Figure 3. Figure 5 illustrates a spacing collar as is obvious.

Numeral 1 is the usual crown adopted for the upper end of the traveling valve, with top screw threaded for connection with the usual sucker rod (not shown). Within the crown is seated a ballvalve. Because of the novel construction hereinafter set forth the aperture in the seat may be increased in diameter, permitting a quicker stroke of the traveling valve and a greater volume of fluid to pass therethrough.

Numeral 3 is the cylinder having shoulder 4 and screw threaded at top for securely attaching same to the crown 1. Numeral. 5 is a collar slidably mounted on cylinder 3. Said collar is constructed with a central shoulder with a diameter slightly in excess than its upper and lower extensions, said extensions having the lower portions beveled inwardly as shown. Cylinder rings 6 are constructed of resilient metal of the same contour as the extensions on collar 5 but slightly less in width than the length of said extensions to permit them to move easily. Said rings 6 have a groove, triangular in shape, at the top for the purpose of giving a sharp edge at their greatest diameter and where they contact with the inner surface of the working barrel (not shown) and are split diagonally as shown at 8 to give them an outward spring to normally contact with the inner surface of the working barrel.

Numeral 9- designates a spacing collar slidably mounted on cylinder 3 of the same outward diameter as the shoulder on collar 5, and may be of any desired length.

ing barrel, and in the upward movement the resilient rings pressing outwardly against the inner surface of the working barrel keeps said inner surface free from sand or any foreign substance disposed to lodge It is understood that the form of the invention herewith shown and described is to be taken as a preferred exampl of the same and that various changes in the shape, size construction and arrangements of parts. may

be resorted towithout departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1

. claim:

1. A traveling valve for the working barrel of an .oil well pump, comprising an upper crown within which is seated a ball valve, aflcylindrical shank connected thereto, a. collar s-lidably mounted on said shank and having a shoulder centrally thereon with extensions above and below said shoulder, the lower portion of said extensions being beveled inwardly, cylinder rings fitted thereon of the same contour as said extensions but slightly less in width than the length of said extensions. said rings having been split diagonally for outward resiliency, a crown secured to the lower end of said cylindrical shank to hold said collars rigidly in place and permit the easy movement of the rings laterally.

2. Ac traveling valve for the working barrel of an oil well pump, comprising an up per crown within which is seated a ball valve. a cylindrical shank connected thereto.

a collar slidably mounted on said shank and having a shoulder centrally thereon with extensions above and below said shoulder the lower portion of said extensions bein beveled inwardly, cylinder rings titte thereon of the same general contour as said extensions, said rings being constructed of resilient metal and having a triangular groove in the upper edge, and being slightly less in width than the length of said extensions and split diagonally, a spacing collar, a second collar and pair of rings conforming in size and shape to said first mentioned collar and rings, a lower crown securely attached to the lower end of said cylindrical shank to hold said collars firmly in vertical position and permit the easy movement of said rings laterally.

In testimony whereof I afliX my signature in the presence of two witnesses.
