PUMPING EQUIPMENT.
Application filed March 20, 1925.
This invention relates to pumps especially adapted for use in wells, and is a continuation in part of our application, Serial Number 709,746, filed April 29, 1924.
The pumps we manufacture are provided with a cast iron barrel in which the plunger reciprocates, and this barrel is sometimes broken or crushed when a wrench is applied thereto for either attaching or detaching the barrel thereby 'rendering the barrel unfit for further use.
Therefore, an important object of this invention is to provide a barrel having a separate attaching coupling of suitable stout and hard metal by means of which the same may be connected to the bushing or detached therefrom without the possibility of crushing or cracking the barrel.
A further object of the invention is to provide an attaching coupling for a working barrel which not only provides a strong wrench contact surface, but also provides an enlarged chamber for the reception of a standing valve whereby the free movement of the Huid upwardly through the barrel from the standing valve is provided for.
Also an important aim of the invention is to provide a bushing having its ends provided with stepped threaded surfaces so located and arranged that the machine work necessary to finish the bushing is reduced to a minimum.
.A further object of the invention is to provide a pump which is of highly simplified construction, easy to handle and durable in use.
Uther objects and advantages will be apparent during the course of the following description.
In the accompanying drawing forming a part of this application, and in which like numerals are employed to designate like parts throughout the same- Fig. 1 is a fragmentary sectional view through a pump, the view illustrating the improved bushing and coupling and the enlarged chamber for the reception of the standing valve.
2 is a group perspective illustrating the improved coupling and bushing.
ln the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates the improved pump consisting of a shell 6, upper and lower bushings 7 and 8 respec- Serial No. 17,019.
tively, a standing valve 9, and a plunger 10.
Referring first to the lower bushing 8 it will be seen that the same is provided with stepped surfaces 11, 12 and 13 at the upper portion thereof, which stepped surfaces are separately threaded while the bushing is attached to the chuck of a lathe. That is to say, the casting from which the bushing 8 is formed is attached to the chuck of a lathe, .nd while in this position the threads on the stepped surfaces 11, 12 and 13 are separately cut. Thus with one application of the bushing` to a chuck, the surfaces 11, 12 and 13 may be provided with threads thereby avoiding the necessity of setting up the job anew for each thread to be cut.
W' hen the threads on the surfaces 11, 12 and 18 are properly formed the bushing is reversed and again applied to the chuck and the threads 16 and 17 formed in the bore 18 of the bushing, all without removing the bushing from the lathe. Therefore, all the internal and external threads on the bushing S may be applied with only two chuck operations. The internal threads 16 and 17 are employed for connecting the members 2O and 21 of a gas anchor to the bushing. By attaching the members 20 and 21 to the inside of the bushing 8 the lower portion 25 of the bushing is left entirely free for the application of a wrench thereto.
The barrel 30 is provided at its lower end with an attaching coupling 31 of a suitable stout steel or other metal of a greater internal diameter than the internal diameter of the barrel 30 whereby to provide an enlarged chamber for the reception of the standing valve 9. The standing valve 9 is positioned within the coupling 31 as shown in Fig. 1, so that the fluid may easily pass through the standing valve and up into the working barrel. In other words, the enlarged Coupling 31 provides a generous space about the standing valve 9 so that the move ment of the Huid upwardly into the barrel is not in any Way obstructed.
After the barrels have been in use for some time it may be necessary to renew the standing valve 9 or other part of the barrel, and to do this, it is merely necessary to remove the shell 6 and apply a wrench directly to the steel coupling 31 and turn the same with sucient force to remove the coupling from engagement with the stepped surfaces 12. The operator can do this with- It is thus seen thatlthe attarzhing Cou.
vplng 3l not only provides a' more durable connection for the barrel 30,. but also an 'enlarged chamber for the reception of the stndlng valve and a means;` whereby the life of the pump is greatly lengthened. Claims:
