P. T. SPRUILL RIVET CATCHER FOR OIL WELL PUMPS Filed Nov. 1921 Patented Au 21, was.
PATTERSON T. srnornn. or VALENTINE, TEXAS.
RIVET carotene non OIL-WELL PUMPS.
Application filed November 9, 1921. Serial 1310 514,928.
To all whom it may concern: '7
Be it known that PATTERSON T. SPRUILL, a citizen of the United States residing at Valentine, in the county of deft Davis and State of Texas, has invented certain new and useful Improvements in Rivet Catchers for Oil-Well- Pumps of which the foll'owin is a specification.
lily invention relates to improvements in rivet catcher for oil well pumps.
The object of my invention is to provide an attachment for the ordinary well known pumps for oil wells which is adapted to catch. the sand, gravel, or rivets which may pass down thewell casing and prevent the same from passing to the ball valves and the pump packing of the piston and thus insure the accurate Working of the ball valves and" prevent injury to the piston packing.
Another object of my invention is to provide anattachment of this character adapted to be readily attached or detached from.
the ordinary oil pump piston without any changes whatever and in which the usual operation of the piston is not afi'ected whether the same is applied or not.
A still further object of the invention is to provide a simple cheap and effective attachment of this character adapted to be held in position by the usual polish rod and having certain details of structure and combination of parts hereinafter more fully set forth. r
In the accompanying drawings:
Fig. l is a vertical sectional view of a deep well piston cylinder showing the well known pump piston with my improved rivet catcher applied.
Fig. 2 is a transverse sectional view taken on the line 2- -2, Fig. 1, looking downwardly or in the directionof the arrow;
Fig. 8 is a transverse sectional view taken on the line3 3, Fig. 1, looking in the direction of the arrow.
Fig. at is an enlarged vertical sectional view showing the catcher or guard showing the manner of attaching it to the pump piston and showing how the packing is secured thereto.
Referring now to the drawings:
1 represents thepump cylinder, which as p is understood, is secured in the lower end of the well casing in any desired manner and needs no further description. Working in the said cylinder is the pump piston 2, which is of the double ball valve type as shown and while I have shown and described my catcher or guard as applied to this type of pump piston it will be uiulerstood that it could be applied to any form of pumppiston. In the for-mot pump piston shown, the upper end is provided with a'threadedopening 3 into which is secured thelower threaded end 4 of the polish rod 5 and by means of which the pump piston is operated'as is well understood. In oil wells of this character considerable trouble has been caused from rivets. gravel and the like dropping down the well casing and finding their way down into the valve either pre venting the proper seating of the ball valve; or getting in'between the pump cylinder and the packing and cutting or breaking the same so that the efficiency of the pump pie ton is greatly lessened and the flow of the oil reduced and it is the object of this invention to prevent the passage of anything to the pump piston.
The catcher or guard 6'consists of a cylindrical body like member having its upper end open and the lower end '7 closed. This closed lower end is perforated at 8 for the purpose of allowing of the free upward pas sage of the oil yet preventing the passage of rivets orthe like to the valve. The lower end 6 of the catcher is provided with a central opening 9 through which passes the threaded end of the polish rod 5 and inter posed between the catcher and the valve is a lock washer 10 to prevent the valve from unscrewing from the polish rod. The polish rod is provided with a flange 11 above the threaded portion 5 and which is adapted to engage the bottom 7 of the catcher or guard and tightly clamp the same on the pump valve.
The catcher or guard 6 is of a cylindrical form to fit the pump cylinder 1 and has a reduced upper end 12 externally threaded at 18. Screwed upon the threaded portion 13 is a packing retaining ring 14 adapted to clamp the lower inwardly turned end 15 of the cup shaped packing 16. The ring 14 is provided in its upper face with notches 17 for receiving a spanner wrench and. whereby the ring is adapted to clamp the portion 15 of the packing ring 16 tightly upon the fiangelS formed by the reduced portion of the catcher. The outer periphery of the packing as shown, closely fits the Wall of the pump cylinder and prevents anything from passing down to thepump packing and the valves. V
While I have shown and described this specific manner of securing the packing to the catcher or guard it will he understood that this may be changed Without departing from my invention. U
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is: j
1. The combination with an oil well pump piston, of a catcher secured thereon by the connection of the polish rod. to the pump piston and having a packing adapted to engage the walls of the pump cylinder; 2. The combination with an oil well pump piston of a catcher resting upon the upper end thereof and having a packing adapted to engage the Walls of the pump cylinder and a polish rod passing down through the catcher and clamping the same upon the upper end of the pump piston.
3. The combination with an oil well pump piston, of a catcher resting upon the'upper end thereof and having; a packing adapted to engage the wall oi the pump cytinden and a polish rod passing down through the catcher and having a threaded lower end secured into the pump piston and a. flange above the threaded portion epgaging the catcher and clamping the same on the upper end of the pump piston 7 4%. The combination with an'oil well pump piston, of a catcher resting upon the upper end thereof and of a cup shape having an open upper end externally threaded, a packing surrounding the same, a ring screwed on the threaded portion on the inside of the oackin and clamnin the same thereto. said catcher having a strainer portion, and a polish rod passing through theopen upper end of the catcher and through the bottom and having athreaded lower end screwed into the pump piston, and said rod having a flange above the threaded portion engag-j and a polish rod passingithrough the catcher the pump piston.
In testimonv whereof I aflix my sm'na-ture.
