Patented July 12, 1932 UNITED. STATES PATENT OFFICE WILLIAM E. A. PIPHER AND ALVIN n. PIPHER, PARKEBS A DING. PENNSYLVANIA OIL Aerrnron' Application filed July 18, 1931. Serial No. 551,806.

This invention relates to an. oil agitator As is well known to those skilled in the art more oil can be bailed from an old well than can be obtained by pumping. This is due to the fact that the bailer, when moved up and down through the oil stirs it thor- 19 oughly and washes the rock, thereby allowing the oil to flow more freel into the well. As a means for increasing ow some operators have drilled small holes part way through the ball in the standing valve so that when the hole in the ball turns to the right position it allows a jet of oil to shoot back into the well so as to stir the oil in'the well. At best this method is very unreliable. It is an object of the present invention to provide a positive agitating means for the oil, said means being actuated by the movement of a valve which, in turn, is operated by the suction of oil through the working barrel.

Another object is to use an agitating device located outside of the tubing where it can readily churn or agitate the oil and keep the rock free from paraffin.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combi nation 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 departing from the spirit of the invention.

In the accompanying drawings the pre-' ferred form of the invention has been shown.

In said drawings:

Figure 1 is an elevation of the device attached to a working barrel in place of the usual perforated tubing anchor.

Figure 2 is an elevation view at right angles to Figure 1. V

-lower. gend,of the working barrel.

Figure 5 is an enlarged section on line 5 5, Figure 1. v

Figure 6 is an enlarged section on line 66, Figure 1.

Referring to the figures by characters of reference, l designatesthe lower end of a working barrel engaged by a coupling 2 which supports the tubing 3 forming the body portion of the present invention. A head 4 joins the tubing to the sleeve and has a central "1 countersunk bore 5 about which is arranged a series of small openings or ports 6. The space between headeand working barrel 1 forms a Valve chamber 7 in sleeve 2. The lower end of tubing 3 is engaged by collar 8 which supports ,a spacing ring?) loosely mounted on the tubing; A pin 10 limits the movement of this ring. Another spacingringll is carried by head 4 beneath sleeve .2. 1 V

. Longitudinal slots 12 are formed in the tubing 3 and extending loosely through them is a diametrical cross bar 14 the ends of which are fastened to an agitating ring 15 slidable spring 16 extendingloosely around tubing 3 and slidable thereon.

-A flat'valve 17 normally closes the ports 6. A rod 18 is secured at its upper end-to this valve and extends downwardly through bore ball 14:. j

The tubing is adapted to be substituted for the perforated tubing usually attached to the the alternate or; upstrokes of the working valve (not shown) the oil will be sucked through slots 12 and upwardly through ports 6, at the same time lifting .the flat valve 17 Thus the bar 14 and ring Will be elevated along tubing 3 and correspondingly move the spring 16. When the suction ceases and the valve 17 drops the rod 18 and the parts connected thereto will also drop.

Spring 16 and ring 15 will-act to churn the oil and keep the rock washed thoroughly and while means other than a spring could be used as an agitator, it is preferred to employ a spring because it vibrates more readily and;

During" on tubing 3. Thisring supports a coiled 5. The lower end of the rod is attached to thus acts better as an agitator than would rigid devices.

If preferred a flood hole 19 can be provided in head 4 although this is not necessary.

Whatis claimed is: I 1. An oil agitator for attachment to the lower end of a working barrel, including a tubing having ports at its upper end and a slot in its wall, a valve normally closing theports and liftable by suction in the. working. barrel, an agitator slidable along the outside of the tubing, and a connection between'the Valve and agitator, said connection working in the slot.

2; An oil agitator for attachment to the I lower end of a working barrel including a tubing having a port in its upper end, a valve normally closing the port and liftable by suction in the working barrel,"an agitator operated'by said valve, said agitator including a ring slidable on the tubing, and a connection between the'ring and. valve, said tubing being'slotted for the connection. 7

An oil agitator for attachment tothe lower end of a working barrel including a tubing having a port in its upper end, a valve 1 normally closing the port and liftable by suction in the working barrel, an agitator operated by said valve, said connection including a ring, a. cross bar connected thereto and slidable. in the tubing, a rod connecting the bar and valve, and anagitatoron the ring and tubing.

4:. An oilagitator for attachment to the lower end of a working barrel including a tubing having a port in its upper end, a valve normally closing the port and l iftable by suction in the working barrel, an agitator operated by said valve,'said connection including a ring, a cross bar connected thereto and slidable in the tubing, a. rod connecting the bar and valve, and an agitating spring supported by the ring and slidable on the tubing.

5. A structure for attachment to the lower end ofa working barrel, a suction operated valve, and oil agitating means operated by the valve for working between said structure s and the side wall of a well.

Intestimony that we claim the foregoing as our own, we have hereto aflixed our signatures.
