LOWER PUMP VALVE ASSEMBLY Filed Jan. 19, 1927 I/V VENT-072. ZEN/EL E. Z3YR5 Patented Sept. 3, 1929.
UNITED STATES DANIEL E. BYERS, OF LONG BEACH, CALIFORNIA.
LOWEBr-PUMP-VALVE ASSEMBLY.
Application filed January 19, 1927. Serial No. 162,158.
tively held in its mounting during the operation of the pump.
Another object is to provide means whereby the locking arrangement may be longitudinally adjusted so as to positively seat the assembly in its mounting.
A further object is to provide a valve assembly of the character stated in which the locking members may be hardened, thus materially increasing the useful life of the de- Vice.
Still another object is to provide a removable locking means which may be readily re placed when worn.
Other objects, advantages, and features of invention may appear from the accompanying drawing, the-subjoined detailed descrlption, or in the appended claims.
In the drawing Fig. 1 is a longitudinal sectional view of my lower pump valve assembly in operative position in a pump.
' Fig. 2 is a longitudinal sectional view of my locking shoe.
Fig. 3 is a plan View of the lower valve cage.
TX mounting block 1 is secured to the lower end of the tubing 2 in which the pump 3 is mounted. The block 1 is provided with a seat 4 at the upper end thereof, the purpose of which will be further described.
The tubular looking shoe 5 comprises an upper section 6 and a lower spring dog sec tion 7. The upper section 6 is formed with a conical ring 8 adjacent the upp er end thereof, which ring is adapted to rest on the seat 4 and thus prevent the liquid from passing downwardly through the mounting block 1. -A threaded section 9 is formed on the upper end of the locking "shoe 5 which is adapted to receive the cage 10. The cage 10 is thread- Referring more particularly to the draw-- ed on the section 9 and holds the usual valve seat 11 upon which the ball 12 is adapted to rest. A transverse bridge 13 is integrally formed adjacent the upper end of the cage 10 and a plurality of holes 14 extend there through to permit the passage of liquid.
A bumper pin 15 projects downwardly from the bridge 13 and is integrally formed therewith, the purpose of saidpin being to limit the upward movement of the ball 12. Also this pin prevents the ball from lying over the holes 14 to obstruct the free passage of the liquid through the holes. The upper end of the cage 10 may be either internally or externally threaded as desired to receive the piston section 16 or the pump barrel, de-
pending upon which type of pump the as sembly is used with.
The lower spring dog section 7 is formed of a hardened material and is threaded onto the lower end of the upper section 6, as shown at 17. Aplurality of longitudinally ex- I tending slots 18 are formed in the section 7 to permit the collapse of the lower end thereof when the assembly is withdrawn from the well. 'A sleeve 19 screws into the lower end of the block 1 and is provided with a ring seat 20 which seat is hardened to resist wear.
An annular groove 21 is formed adjacent the lower end of the dog section.7 which groove is adapted to fit into the hardened seat 20. The outward tension of the 'dog 7 serves to securely hold the assembly in position in the block. The seat 20 and dog section 7 are both hardened and will therefore resist-wear for a greater length of time. If
'or refaced, the locking shoe 5 will extend lower in the block 1 and consequently the sleeve 19 would not hold the shoe tightl in position. To remedy this, I provide a ock nut 22 which screws onto the sleeve 19 and bears against the bottom of the block 1 whereby the said sleeve may be adjusted to the required positionso that the ring 8 is held tightly in the seat 4. Having described my invention, I claim:
1. In a pump adapted to be mounted in tubing, a block on the lower end of said tubing, a locking shoe mounted in said block, said shoe comprising an upper section seated in said block, a lower dog section, a sleeve secured to the lower end of said block, said sleeve being adapted and arranged to receive said locking dogs, and means to adjust said sleeve whereby the locking shoe is tightly held in the block.
2. In a pump adapted to be mounted in tubing, a, block on the lower end of said tubing, a locking shoe mounted in said block, said shoe comprising an upper section seated in said block, a lower dog section, a sleeve threaded into the lower end of said block, and a lock nut threaded onto said sleeve against said block whereby the sleeve may be adjusted to hold said locking shoe in seated position in the block.
3. In a pump adapted to be mounted in tubing, a block secured to the lower end of said tubing, a seat adjacent the upper end of said block, a hollow locking shoe, a ring on said shoe adapted to seat on said block seat, locking dog section on the lower end of said locking shoe, said dog section being threaded to the upper section, and adjustable means adapted to engage said dogs to hold the locking shoe in seated position.
4, In a pump adapted to be mounted in tubing, a block secured to the lower end of said tubing, a seat adjacent the upper end of said block, a hollow locking shoe, a ring on said shoe adapted to seat on said block seat, locking dog section on the lower end of said locking shoe, said dog section being threaded to the upper section, adjustable means adapted to engage-said dogs to hold the locking shoe in seated position, said means comprising sleeve threaded into said block, and a lock nut threaded onto the sleeve against said block.
5. In a pump adapted to be mounted in tubing, a block on the lower end of said tubing, a locking shoe mounted in said block, said shoe comprising an upper section seated in said block, a lower dog section, means on said block adapted to receive said dogs, a
.valve cage secured to the upper end of said locking shoe, said valve cage comprising an integral bridge having'a plurality of holes extending therethrough, and an integral v bumper pin depending from said bridge.
6. In a pump adapted to be mounted in tubing, a block secured to the lower end of said tubing, a seat adjacent the upper end of said block, a locking shoe comprising an upper seating section, a ring on said upper section adapted to rest on the lock seat, threads whereby the locking shoe is securely held in seated position.
In testimony whereof, I aflix my signature.
