PUMP.
Application led March 1, 1926. Serial No. 91,548.
This invention aims to provide a novel means whereby a pump barrel may be lowered into a casing in a well, and be with-v drawn therefrom, without dificulty.
1t is within the province .of the disclosure to improve generally and to enhance the utility of devices of that type to lwhich the invention appertains.
With the above and other objects in view which will appear as. the'description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it' being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without Adepartin from the spirit of the invention. 1n t e accompanying drawings :e v Figure 1 shows in longitudinal section, a device constructed in accordance with the invention, the barrel being held in the cas- Ul':
Figure 2 is a longitudinal section vwherein the parts are shown as they will appear. when the operation of pulling out the barrel is about to be begun; y
Figure 3 is a detail enlargedy from Figure 1;
Figure 4 isa sectional top plan;
Figure 5 is a cross section taken about on the line 5-5 of Figure 1.
The numeral 1 marks a tubular' casing..
The casing 1 has an enlarged upper end 2. rl`he end 2 of the casing is connected, vin Iany desired way, with the well tubing (not shown). At its lower end, the Casin 1 has a tapered bore 3. A barrelv 4 is disposed in the casing 1. The barrel 4 has a tapered end 5. The tapered end 5 of the barrel 4 is seated in the tapered bore 3 of the casing 1. Intermediate its ends, the barrel 4 is supplied with internalv projections 6. A.
holder 7 in -theform of. a ring, is threaded or secured otherwise in the end 2 of the casin 1. Longitudinal, transverselys aced, resi ient keepers 8 are provided, T e upper ends of the keepers 8 are secured to the ring' 7. The lower ends of the keepers 8 extend below the ring 7 and are free. The lower ends of the keepers 8 have shoulders or the like, shown at. 9. The keepers 8 tend to spring inwardly, so as to cause the shoulders.
9 to engage the upper end of the barrel 4 and tohold the barrel down. .The hold of the shoulders 9 on the upper end of the barrel 4 is enhanced, because the keepers 8 are supplied, intermediate their ends with outwardly extended resilient arms 10 which bear on the ring 7 and aid in swinging or springing the lower ends of the keepers 8 inwardly. On the inner surfaces of the lower ends of the keepers 8 there are inwardly extended rounded lugs 11. A plunger 12 reciprcates in the barrel 4. The plunger 12 is a comH posit/e structure. lt includes a piston 14, a cage 15 mounted on the piston, a downwardly closing ball valve 16 in the cage, and a coupling 17 `connected to the cage. An operating member 18, such as a rod, is assembled at its lower endwith the coupling 17. The
A cage 20 is shown, and the body. 21 of the cage is threaded at 22 into the lower end of 4 from the casing 1, the plunger 12 is pulled upwardly by the rod 18 until the releaser 19 engages-the lugs 11 on the keepers 8 and swings the keepers outwardly, out of en gagement with the upper end of the barrel 4, as shown in Figure 2. Some part of the plunger 12, generally the base ot the cage 15, comes into contact withthe projections 6 on the barrel 4, and, thus, the barrel may be pulled out of the casing 1 readily, along with the rod 18. By a reverse operation, which will be understood readily when Figure 2 is examined,the barrel 4 may be lowered into the casing, and when the releaser 19 moves downwardly out of engagement with the lugs 11, the' keepers 8 will engage vwith the' upper end of the barrel 4, as depicted in Figure 1. l
- en the rod 18 makes an ordina-ry stroke to consummate the pumping operation, the releaser 19 does not come into contact with the lugs 11 on the keepers 8, nor does the plunger 12 come into contact with they -projections 6.
one end of the casing, a spring keeper se-4 cured at its upper end rigidly to the ring,

In testimony that I claim the foregoing as my own, I have hereto alixed my signature.-
