` 1 Claim.
This invention relates to scavenger barrels for pumping oil wells and has for an object to provide a novel shell and barrel coupling collar for permitting sediment that may settle in the sand shell outside of the barrel to be easily removed.
A further object is to provide a scavenger barrel having a novel valve adapted to seal the open top of the barrel, and deflect sand and scale into the space between the working barrel and the sand shell.
A further object is to provide apparatus of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.
With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim Without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawing forming part of this specification, v
Figure l is a longitudinal sectional view of the upper portion of a scavenger barrel having a sand and scale deecting valve constructed in accordance with the invention.-
3o Figure 2 is a longitudinal section of the lower portion of the scavenger barrel, forming a continuation of the parts shown in Figure 1, and showing the removable barrel and shell coupling collar at the bottom of the |barrel.
Figure 3 is a cross sectional view taken on the line 3-3 of Figure 1 showing the openings which permit the escape of uid from the scavenger barrel into the sand shell.
Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1 showing the pins carried by the sand shell for centering the scavenger barrel in place. y
Figure 5 is a cross sectional view taken on the line 5-5 of Figure 2 showing the collecting space for sand and scale.
Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates the scavenger barrel, I I the sand shell, I2 the sucker rod, I3 the 5o sucker rod working valve, and I4 the lower working valve, at the bottom of the scavenger barrel, these parts being conventional in oil well pumping equipment.
In carrying out the invention a short length 55 of tubing I5, is secured by welding, as shown at I6, to the bottom of the sand shell and is provided l at the bottom of its inner face with a screw threaded shoulder I'I. A coupling collar I8 is threadedly engaged with the shoulder and is threadedly engaged with the bottom of the scav- 5 enger barrel, as shown at I9. Thus the shell and scavenger barrel coupling collar I8 is removably secured in place and may be easily and quickly detached to permit sand and scale being removed from the space 20 between the scavenger barrel 10 and the sand shell.
By referring to Figure 1 it will be seen that the scavenger barrel I0 is open at the top and is provided near the open topwith a plurality of openings 2|. A plug valve 22 is slidably fitted on 15 the sucker rod I2 and is provided at the top with a circumferential shoulder 23 adapted to t on the top edge of the scavenger barrel II). The valve is of such length as to seal the openings 2| when the valve is seated and has the top surface 20 arched to deflect sedimentary material. Whenv the valve is lifted from its seat liquid may flow from the scavenger barrel through the openings upwardly through the sand trap and any sand or scale mixed therewith will settle in the collecting 25 space 20 between the sand shell I I and the scavenger barrel I0 for subsequent removal. When the well is not in action the valve 22 is in closed position and in case the fluid pump contains sand or if scale gravitates down the tubing or rods, the 30 valve deects the scale or sand from the scavenger barrel so that it will not settle around the working valve I3.
The center of curvature of the arched or convex top surface of the valve is approximately in 35 the plane of the openings 2| on the sucker rod I2 to provide a gently sloping top surface for effectively directing the extraneous material outwardly beyond the shoulder 23.
For the purpose of mounting the valve 22 the scavenger barrel I0 is open at the top contrary to the usual practice. For supporting the scavenger barrel and centralizing the same'in' the sand shell a plurality of pins 24 are welded or otherwise secured to the inner face of the sand 45 shell II and extend to the scavenger barrel as best shown in Figures l and 3.
Since the operation has been'described as the description of the parts progressed it is thought that the invention will be fully understood without further explanation.
What is claimed is:
In oil well scavenger apparatus, the combination of a barrel, a sand shell surrounding and spaced from the barrel, a removable collar couof the valve, said valve having a onvex top surface with its center of curvature approximately in the plane of said openings and on said sucker rod for deflecting sand and other material into the collecting space between the barrel and the 5 Shell.
