' MULTIPLE-TUBE Application filed May 2,
over the foot valve of the pump at each stroke of the pump, thereby keeping the valve clean and preventing the failure thereof.
v A further object is to provide a multiple tube inserted pump in which the standing valve and traveling valve are only positioned at a short distance apart in `the lower position of the pump.
Still another object is to provide a pump which is effective in operation, which will not become easily disarranged,'and which may be removed from the well at the time of the removal of the sucker rods.
Other objects, advantages, and features of invention 4may appear from the accompanying drawing, the subJoined detailed description, and the appended claims.
In the drawing: v
Fig. 1 is' a fragmentary, longitudinal, sectional view of a three-tubetype of pump.
Fig. 2 is a, fragmentary, longitudinal, sectional view of a two-tube pump.
Fig. 3 is a fragmentary, longitudinal, sectional view of the pump shown in Fig. 1, the view being above that shown in Fig. 1.
Referring more particularly to thedraw'- ing:' Y The usual sleeve 2 at the lower end thereof in which a pump holding dog 3, of usual construction, is mounted. A The dog 3 -is of the type which locks `in the sleeve 2 but which can be removed by a sharppull on the sucker rods when it is desired to remove thepurnp. The collar 4 is threadedonto the top of the dog 3 and a sta` tionary sleeve 5 screws onto the outside of the collar 4. A foot valve cage screws onto the collar 4 and is spaced from the sleeve 5. A ball 7 is positioned in the cage 6 and the operation and object thereof will be further described.
An inner stationary tube 8 screws into the cage 6 and extends to a collar 9 to which it is secured. The tube 8 screws into the inside of the collar 9 thus providing a space between tlie said tube and the stationary tube 5. A tube 10 screws onto the outside of the collar 9 and rises to a standing valve cage 11 which cage is provided with the usual ball 12. The tube 10 is threaded onto .the usual couwell tubing 1 is provided with a- INSERTED PUMP.

8 and 5 as well as the dog 3 and parts integral therewith.
A fluid passage 17 is provided between the cage 6 and tube 5, and ports 18 extend from the passage 17 through the wallof the cage 6, saidports being adjacent the ball 7. A traveling cage 19 is secured to the top of the plunger 14 and -is provided with the usual ball 20. vThe sucker rods 21, which reciprocate the plunger 14, are secured to the top of the cage 19 and extend to the top of the well. in the usual manner.
-In order that a constant upward pressure may be maintained on the dog 3, we provide a tapered ring 22 which sits closely within the tubing 1 and the tube 5 is provided with a tapered head 23 which sits'within the ring 22, and a spring 24 bears against the ring 22 and against a shoulder or the top of tube 1 as` shown in Fig. 3. Thus it will be seen that the spring 24 exerts a constant upward tension against the ring 22 and tube 5 which holds all of the stationary parts of the pump inv proper position.
At times it will be desirable to provide a check valve above the cage 19and in this event we thread the tube 5 into a coupling 25, the outer surface of said coupling being tapered to fit into the tapered ring 22` A screw seat 26 threads into the coupling 25 and into a cage 27 through which the sucker rods 2 1 extend. A collar 28 fits closely around the sucker rods 21 and is ada ted: to sit on the top of the screw seat 26, t us providing Aa check and preventing the liquid from moving downwardly in the tubing. On the up-stroke of the pump, the collar 28 lifts permitting the passage of fluid through the cage 27 and into the tubing 1.
In operation the plunger 14 is reciprocated by the rods 21 and on the up-stroke ofl the plunger the spaces 15, .17 are filled with liquid simultaneous with the'filling of the pump. During this upward movement of the plunger, the ball 20 is seated and the balls 7, 12 are lifted permitting the filling of the pump. On the down-stroke the balls 7, 12
are seated and the ball lifts, thus-carrying the fluid into the tubin 1. During the downstroke of the plunger t e liquid in the chambers 15, 17 is forced through the ports 18 into the cage 6, thus washing over the ball 7 and removing all sand and sediment therefrom. Thus it will be seen that this ball is always clean and all sand, and so forth, removed from the seat thus assuring that it will be properly cleansedat all times.
In the forni of our invention shown vin Fig. 2, the usual tubing 29 is provided with a sleeve 2 in which the dog 3 is mounted, as previously described. A foot valve cage 30 screws onto the top of the dog 3, said cage being provided with a ball valve 31. A stationary tube 32 screws into thc cage 30 and l a coupling 33 is mounted on the top thereof.
A second stationary tube 34 `threads into the coupling 33 at the bottom and onto a standing valve cage 35 at the top, said standing valve cage being provided with a ball valve 36.
A plunger 37 fits closely within the tubing 29 and around the cage 35 and tubing 34.
A uid space 38 is provided between the inside of the plunger 37 and the\outer surface of the tubing 32. A foot nipple 39 screws onto the bottom of the plunger 37, said nipple being adapted to engage the coupling 33 to affect the removal of the pump from the Well.
A lluid passage 40 is provided around the cage 30, said passage communicating with the chamber 38 by reason of the fact that the nipple 39 fits loosely aboutthe tube32. Ports 4l are provided in the wall of the cage 30,
said ports being adjacent the ball 31 and they purpose of these ports will be further described. A cage 42 screws onto the top of the plunger 37 and the usual ball check 43 is seated in the cage. The sucker rods (not shown) are secured to the cage 42 to reciprocate the plunger 37.
In operation as the plunger 37 is moved upwardly the balls 31, 36 are unseated permitting the uidvto pass into the pump and the ball 43 remains seated.` During the upward movement of the plunger the passage 40 and chamber 38 are filled with a liquid, and on the down-stroke of the plunger the balls 31, 3 6 are seated while the ball 43 rises, thus moving the fluid into the tubing, and also during the down-stroke of the plunger the liquid in the passage 4Q is forced through the ports 41, washing over the ball 31 tothoroughly cleanse the same in a manner previously described under Fig. 1. At the ex-m treme down-stroke of the plungers in 'both Figs. 1 and 2, the standing valves 11, 35 are close to the traveling valves 19, 42, thus tend-l ing to force practically all of the liquid in he pump upwardly past the ball checks Having described our invention, we claim:
