CHARLES W. BELL, or BAn'rLnsvILLE, OKLAHOMA;
PUMP FOB OIL AND LIKE WELLS.
y `.To all whom it may concern.'
Be it known that I, CHARLES W. BELL, a citizen of the United States, and resident of Bartlesville, in the county of Washington and State of Oklahoma, have invented a new and useful Improvement in Pumps for 'Oil and like `Wells5 and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to like wells.
In a patent granted to me May 9th, 1911, 991,600, there is set forth and claimed a method of reducing the wear of valves and plungers in oil-well pumps, said` method consisting in separating the gas from the; oil and admitting the gas thus separated from the oil to and around said valves and: plungers, thereby sealing the same against,` the entrance of liquid. By this method the pumps for oil and fine sand which is present in the oil, due to the shooting of the well, is prevented from settling on the valves and plungers, and causing the rapid wearing away of the cups and packing. f
The object of the present invention is to provide a simple form of apparatus for carrying out the above method, and to these ends my invention comprises the novel features hereinafter set forth and claimed.
In the accompanying drawing, Figure 1v is a vertical section of my improved pump, with the piston ascending; Fig. 2 is a like view, showing the piston descending, and Figs. 3 and 4 are enlarged sections; Fig. 5 is av cross section on line 5-5, Fig. 4.
Referring to they drawing, the numeral 2 designates the working-barrel which is threaded into thecollar 3 at its lower end. Threaded into the collar 3 is the perforated pipe 4, through which the fluid passes from the well into the pump. In the collar Sis formed the tapered shoulder 5, which forms the support for the ordinary standing valve 6. This valve is provided with the cage 7 and the ball-valve 8. The upper end of the working-barrel 2 is threaded into the enlarged extension 9. The upper end of the extension 9 is connected tothe tubular sec- .tubing 12, leading to the ytop of the well.
Within the working-barrel 2 is the ordinary cup-piston or plunger 13.y The upperA Specification of Letters Patent.

end ofthe plunger 13 is threaded `into the valve-member 14. This valve-member 14 forms the housing for'the. ball-.valve 15, and has the shoulder 16, which forms a rest for the valve-seat 17, and by means of which said valve-seat is held in place on top of the plunger 13.
The valve-member 14 is provided with the apertures 18, which form a passage-way for the fluid to pass from the housing into the tube 19, which is threaded to the upper end of the valve-member 14. The tube 19 being connected to the valve-member and the valve-member in turn to the plunger, the tube 19 thus becomes a part of said plunger and moves up and down therewith.
ber is held within said tubular extension by means of the expansible ring k23 which is heldlbetween thecollar 24 and the shoulder 25. The packing-cup 26 rests on the upper end ofk the collar 27, which is threaded to the member 22, and said packing-ring is forced out against the inner walls of the tubular section 10 by the expanding ring 28. This expanding ring 28 is preferably a splitk steel ring with suficient expansion action to force the packing 26 tightly against the inner wall of the tubular section 10, so as to prevent the fluid 4from getting in from ]above, or the gas from getting in from be- A tube 29 is connected to the lower .end of the collar 27 and said tube extends down within the tube 19 to a point adjacent to the valve-member 14.
In the operation of my improvedgpump, when the plunger is raised, asl shown in Fig. 2, 'the fluid enters the well and passes up through the valve 8 into the lower end of the working-barrel while the valve 15 lis closed. Upon the descent of the plunger, the valve 8 is closed, and the fluid passing up through the plunger lifts ythe valve 15 which permits the fluid topass. on up above .the plunger and into the pipe 19. At the same time that the oil and gas mixed therewith passes into the tube19, said tube 19in its descent, creates a partial vacuum yat its upper end in the chamber 9*, which draws in and 29, will separate, and the gas will rise into the chamber 9a. Then the Lip-stroke comes, the displacement in the chamber 9av made by the tube 19, will force the fluid down from between 19 and 29 into 19, and in this manner the chamber 9a will gradually be filled with gas. p
The length of the'tubes 19v and29 is determined by having the tubes lap the length of the stroke, plusl space enough, and a little more, to makeup for the partial vacuum caused by the tube 19 on down-stroke. In other words, they tubes must lap enough rl`he important feature of' improvement.- consists of the tubes 19 and 29 which sepai'ate a quantity of gas from the fluidV being,l pumped and hold the gasthus separated in` such a manner that said gasl acts as aI packing between the cups or packingy off the plunger, thus keeping the sand romv reaching these parts after it has passed with the fluid above the plunger. Vhen it is necessaiy to pull the plunger to be: repaired, the rods are drawnup until thel tube 19 comes against the collar 27 where-- upon the member 22, with the attached! parts, is drawn through the tubingand out;
back into place, the shoulder at the top of the piston-rod will force the member 22? and its attached paits down into-the tubularf section 102 until the plunger 13 comes in: contact with the standing-valve 6. The piston-rod 2() is as long as the member 22;' and tube 29, plus the length of the strokel of the pump. If the plunger shouldV bel drawn up too far, themember 22 will adjust itself inthe tubular section 10 tothe stroke of the pump. Another advantage of this self-adjustment is that if' sand should settle in the tube 19 when theV pump is idle and cause the tubes 19 and 29 to stick to gether, they could reciprocate together un til the sand is finally forced out, whereupon the member 22 would automatically adjust section 10.
