. 1 Claim. (@i. 103-179) This invention relates to a traveling cup and stufing box mainly designed for use in pumps of oil wells, the general object of the invention being to provide packing means connected to the pump rod and operating in a stationary barrel so as to prevent leakage of oil at the top of the well and to eliminate the ordinary stumng box and polish rod with the rubber rings now in use. This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. In describing the invention indetail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding which- Figure l is an elevational view showing the upper part of a pump member constructed in accordance with this invention.
Figure 2 is a top plan view of Figure 1.
Figure 3 is a section on the line 33 of Figure 2.
Figure 4 is a detailview of the packing means in the stationary barrel.
Figure 5 is a section on the line 5-5 of Figure In these views the numeral 1 indicates the tubing which has its upper end connected with the T 2 from which leads the outlet pipe 3. A flanged views, and in the internally threaded flange of a cupshaped member 5 which has an upwardly extending sleeve 6 thereon. A barrel 1 passes through the sleeve 5 and is attached thereto by welding or the like as shown at 8 and said barrel passes through the members 2 and 8 and extends into the tubing I. The member 2 is welded to the T as shown at 9 to provide a tight joint between these parts. The lower end of the barrel has a nipple Ill extending upwardly therein and this nipple is of non-circular shape in cross section .to receive the non-circular rod ii forming part of the pump rod, the lower portion of the rod shown at [2 being threaded to the lower end of the rod II. This rod i I is formed with an internally threaded socket I 3 for receiving the lower threaded end of a rod H which has a flange it connected to its upper portion and this rod I4 terminating in an internally threaded'socket It for receiving the upper portion of the pump rod I1, this rod i'l passing through the closure I8 at the top of the 1 barrel with the closure having a vent i9 therein.
and followers 22 are placed above and below the cups, these parts engaging the barrel so as to prevent passage of liquid between them and the barrel during the pumping operation. As will be seen from Figure 3, the liquid will pass up the tube I and flow between the tube and the barrel to reach the outlet pipe 3. The packing member can be expanded by turning the rod ii to turn the rod it, the rod ii being held against turning movement by the non-circular nipple Hi. Thus the flange i5 ismoved downwardly towards the washer 23 which engages the socket i3 and thus the packing members are expanded. By turning the parts in an opposite direction the packing member can be contra ted to permit removal of the parts for repair or other purposes.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.
Having described the invention, what is claimed as new is:
In a pumping assembly including tubing, a T coupling connected to the upper end of the tubing, an outlet pipe leading from the T coupling,
a member connected with the upper end of the T coupling and having a flange at its upper end, a cap detachabiy connected with the flange and having an upwardly extending sleeve formed therewith, a barrel having an intermediate portion passing through the sleeve and connected therewith for removal of the cap and barrel from the tubing as a unit, said barrel extending into the tubing to a point below the -T coupling and said barrel being of smallerdiameter than the tubing and the T coupling to provide a space between itself and'said tubing and T coupling for the passage of liquid from the tubing to the outlet pipe, a vented closure for the upper end of the barrel, the lower end of the barrel being closed and provided with a centrally arranged non-circular opening in said closed lower end, a rod of non-circular shape in cross section passing through the non-circular openingdn the bottom of the barrel, a second rod having its lower end connected with the upper end of the non-circular rod, a third rod passing through the upper end of the barrel and connected to the upper end of the second rod, packing means carried by the second rod and a fixed abutment and a movable abutment on the second rod and engaging opposite ends of the packing means for expanding the packing means by turning movement of the third and second rods.
