VALVE-OPENING DEVICE.l
Specification of Letters Patent.
Patented Feb. 14, 1911'.
Application filed December 17, 1909. Serial No. 533,623. l
To all uiom it may concer/fi: Y
ing.
In deep well pumping it frequentlyy happens that by sand and other matter collectnig on the. valve seat, the valve is prevented from working properly. This difliculty can be readily remedied by opening the valve,`
and letting' the oil or other fluid run back into the well'to wash away theaccumul'ation on the valve seat. It also becomes necessary at times to pull the tubing out ofthe Well, and when this is done itis desirable to first empty the oil r other fluid contained in the tubing back into the well, in order to prevent. the same from being wasted. lVhen ordinary valves are used, this cannot be done and the oil or other fluid is wasted, amounting sometimes to several barrels. However, by the use of my invention, the valves can be readily opened to letthe oil or other fluid run back into the well, and this ma)v also be done if it is desired to flood the well. which is usually done by drilling a hole in the tubing at the bottom of the well, this necessitating a shut down of the pump until the oil or other fluid leaks out..
The invention has for its object to provide a device for the purpose statedwhich is simple in structure, easily1 operated, and eilicient and reliable in action.
ll'ith this object in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed in which,
Figure 1 is an elevation of a standing valve and a pump piston valve showing the application of the invention. Fig. 2 is a central vertical section ofthe parts shown in Fig. 1. Fig. 3 is a view similar to Fig. 2 showing the parts in another position.
Referring to the. drawing, 5 denotes the easing of the standing valve located at the bottom of the well tubing, the latter not being shown. The valve body is provided with a packing leather 6 whereby it is held at a fluid tight.4 tit withinthe well tubing.
The valve casing is tubular, and contains aseat 7 for a ball valve S. the upper end of Athe easing being providedwith a cage 9 inclosing the b'all. '.lhis cage screws on the Vupper end of the valve casing, and has an interior shoulder 10 engageable with one side of an annular flange' 11 on the valve seat,
7 said seat being in the form of a sleeve lit ting inthe bore of the casing 5, and having the other Vside of the flange in. engagement` with the upper end of the easing, against which it is held by the shoulder 10.
Rising from the upper end of the valve` age 9. and formed integral therewith, is a tube 12, in which is slidably mounted a tubular stem 13 having at its lower end an enlargement 14 engageable with a` seat made in the lower end of the tube 12.
On the stem 13, above the upper end of the tube 12, is screwed a sleeve 15 having a. depending tubular portion 1G loosely titting on the tube 12 so that it may slide up and down thereon. Around the stein 13 is coiled a spring 17 engageable at one end with a shoulder 17 1 in the bore of the tube 12, and at the opposite end with the sleeve 15. The tension of the spring 17 may be adjusted by screwing the sleeve 15 up or down on the stein 13.
The stein '13 projects from the upperend of thel sleeve 15, and on said projecting-end is screwed a coupling head 18, between which head and said end of the sleeve is clamped a ring 19 formed with a downwardly projecting linger 20, having its lower end intiirned so thatA it may engage the ball valve 8, and push it ofi' its seat 7. The finger 20 lies in a groove made in the outer surface of the tubular portion 16 of' thc sleeve 15, and itextends through one of the side openings of the cage 9. Into the upper end of the coupling head 18 is screwed a tubular stem 21 which is fora purpose to be presently described. At 22 is indicated the pump piston, the same being tubular, and containing a seat. 23' for a ball valve 24. The stein 21 is in axial alinement with the bore of the piston, and is adapted to 4enter said bore when said piston is lowered sufficiently, so that it may engage the ball valve 24 and lift the same off its seat. The length of the stein 21y is such that it does not unseat thevalve 24 during the nor* mal working stroke of the piston.
To unseat the'ball valve 8, the piston 22 is lowered until the 'stem 21 enters the same, and lifts the valve 24 oii' its seat, the valve being elevated until it engages the upper end of its cage.\A continued downward movement of the piston, vover the rod 21,
slides the sleeve 15 downwardly on the tube` 12, this. downward movement t being con- V and release said valve when the stem 21` is standing valve; of a tube-rising from said,
released by the piston, whereupon the valvedro s back to its seat 7. The valve 24 drops bac to its seat when the piston 22 is returnedvto its working position. y
By the device herein described, the valve can be readily opened to permit the well tubing to empty, the device is simple in structure, and can bel easily operated, and it therefore efectually serves the purpose for which it isA designed. v
What is claimed is 1. In a well, the combination with the valve, a sleeve slidably mounted on the tube, a valve opening device carried by the sleev'e,
and engageable with 'thefvalve ro r when the sleeve is lowered, means fiar .owerin the sleeve, and lyielding means opposing sai movement of the sleeve.I
2. In a well, the combination with Ythe standing valve; of a tube rising from the ca e thereof, `a stem loosely mounted in the tu e, a sleeve carried by the stem and slidably mounted on the aforesaid tube, a valve opening device earriedby the sleeve, and engageable withthe valve proper when saidsleeve is'lowered, and means for lowering the sleeve.
3. In a well, the combination vwith'ithe standing valve; of a tube rising 'from-.the cage thereof, a stem slidably mounted in the tube, a sleeve carried bythe stem, and
slidably mounted on the aforesaid tube, a
coupling head mounted` on the stem, a ring held between f the coupling head and the sleeve, and a valve opening ldevice carried by the ring, and adapted to `engage the valve proper to unseat the same.
In testimony that I claim the foregoing .as myy own, I have hereto valhxed my signature inthepresence of vtwo witnesses.
