WITNESSES IMVENTOR THE COLUMBIA PLANOURAPH :0 WASHINGTON, D. C.
UNITED STATES PATENT OFFICE.
ERNEST BOW ERY, OF OIL CENTER, CALIFORNIA.
OIL-WELL-ZPUMP SHOE.
Application filed May 29, 1919.
To all whom it may concern:
Be it known that I, ERNEST BOWERY, a citizen of the United States, and a resident of Oil Center, in the county of Kern and State of California, have invented certain new and useful Improvements in Oil-Well- Pump Shoes, of which the following is a specification.
My invention is an improvement in oil well pump shoes, and has for its object to provide a shoe of the character specified, wherein the standing valve seat is removable from the shoe without disturbing the shoe.
In the drawings is shown a vertical section of the pump shoe.
In the present embodiment of the invention the improved shoe comprises a lower section 1 and an upper section 2', the upper section having a reduced externally threaded nipple 3 which engages within a reamed or counter-boredportion 4 at the upper end of the lower section. The lower section has an annular inwardly extending rib 5 near its lower end, and the standing valve seat 6 is held within the lower end of the upper section 2 of the shoe, the seat having threaded engagement with the said upper section.
The lower end of the seat rests upon the upper face of the rib 5, and the upper section has an inwardly extending annular rib- 7 at the connection of the nipple 3 therewith. This rib extends inwardly above the upper end of the seat as shown, in spaced relation.
Specification of Letters Patent.
Patented Aug. 12, 1919.
Serial No. 300,542.
The standing valve cooperates with the seat, it being noticed that the upper end of the bore of the seat is flaring. The end of the liner tube not shown is engaged with the internally threaded upper end 8 of the upper section, abutting against the shoulder 9 at the lower end of the said threaded portion. The valve seat 6 it will be noticed has a plain portion extending well below the other section 2 of the shoe, for engagement by a pipe wrench to remove the seat. It will be noticed that the sections are not threaded tightly into contact where they abut, and this provides for a degree of adjustment.
By making the shoe sectional, the top section is left permanently attached to the barrel and there is no a possibility of the liners becoming shifted as is the case when the entire shoe is removed.
I claim:
1. A pump shoe comprising upper and lower sections having threaded engagement with each other, and a valve seat detachably connected with the upper section, the lower section having an annular stop against which the lower end of the seat abuts.
2. A pump shoe comprising upper and lower sections having threaded engagement with each other, and a valve seat detachably connected with the upper section, the lower section having an annular stop.
ERNEST BOWERY.
