corporation of Ohio Application July 23, 1930. Serial No. 469,956
5 Claims. (01. 103-187) It is the object of my invention to provide a double acting pump cylinder.
It is my object to provide a double acting pump cylinder which will largely increase the amount of water delivered for a given size of pumping equipment.
It is an object to arrange all the parts so that they move in a straight line and to provide working apparatus which can be removed to .the surface by pulling on the sucker rod. My invention lends itself to the various diameter sizes and has liberal water ways so that there is no undue friction.
In particular, it is my object to provide the combination of a well casing, a movable cylinder, a stationary tube projecting into the cylinder supporting a stationary bucket, such cylinder being supported by the casing and having a suitable valve for controlling the delivery of fluid thereto from the well, and a valve associated with the movable cylinder for controlling the exit of fluid therefrom.
In particular, it is my object to provide an upper bucket with the traveling cylinder and a stationary tube delivering into the cylinder hav ing a stationary bucket thereon acting as a piston in the cylinder; and the cylinder acts as a piston in the well casing. v
Referring to the drawings, Figure 1 is a section through the lower end of the casing and the mechanism therein which is the object of this invention, the parts in Figure 1 being positioned at the lowest point on the up-stroke.
Figure 2 is a section on the line 2-2 of Figure 1.
Figure Figure 1.
Figure 4 is a section on the line 4-4 of Figure 1. a
Figure 5 is a section similar to Figure 1 showing the parts with the plunger at its highest point and with the relief valve open, it being understood that the opening of the relief valve is not normal but only in case of the necessity for relief of any accumulated fluid in the cylinder below the valve.
Figure 6 is a View similar to Figiu'e 1 showing the parts enlarged for the purpose of clarity.
Figure '7 is a similar view of the lower end of Figure 1 with the parts enlargedv Figure 8 is view of the parts as in Figure 5, enlarged at the upper end of the view.
Figure 9 is a similar view of the lower end of the view.
Referring to the drawings in detail, 1 is a cas 3 is a section on the line 3-3 of ing which is cylindrical throughout its length but at its bottom has a tapered portion 2 which supports a tapered collar 3 upon which is exteriorly threaded the bail or cage having a lower collar 4, spaced arms 5 and an upper collar 6. 0 To the upper end of this bail collar 6 is threaded a stationary tube '7. Within the collar 3 is a passageway 8 closed by the check valve 9 within the cage or bail. Such check-valve carries the uprights 10 and collar 11 within which is located 5 the helical seating spring 12.
The junction between the collar 3 and the casing 1 is sealed by the washer 13.
The stationary tube '7 empties into the space A between the open end of the tube '7 and the bottom of the bucket 14 in a space formed by the moving cylinder 15 which is attached to the bucket 14 and travels with it. The lower end of this space is formed by the stationary bucket 16. There is a space B between the lower end of the bucket 16 and the top of the moving bucket 1'7 carried by the lower end of the cylinder 15, which bucket carries a washer 18, sealing it with respect to the stationary tube '7.
Any accumulation of fluid in the space B is so relieved through the ports 19'- in the stationary bucket 16, which ports are normally closed by a quick acting check-valve 20 seated by the spring 21.
The space below the bucket 18' and above the check-valve 9 is' designated C.
Returning to the upper bucket 14, it is provided with washers 22 for sealing the bucket with respect to the casing 1. The bucket also carries a cage or bail 23 with spaced arms 24 within which operates the check valve 25 under the influence of the spring 26 for controlling the exit of fluid from the passageway A into the space D.
The sucker rod 27 reciprocates the sucker rod bucket 14, the upper bucket, the cylinder 15 and the cylinder bucket 17. When it is desired to pull the entire apparatus from the well, it is observed that by a continued pull on the sucker rod 27, all the apparatus involved herein canbe re moved by the upward swing movement oi the sucker rod.
Opemtion.--In operation, the upward movement of the sucker rod will draw water through the passageway 8 from the well beneath the valve 9 which is lifted by the suction into the space C and likewise into the tube *1. At the same time the sucker rod bucket 14 which has its valve 25 closed. is elevating the liquid in the space D upwardly and out oi. the pump. On. the downstroke of the pump, the check-valve 9 is closed and the descent of the bucket 18 on the cylinder serves to force the liquid from the chaniber C through the pipe 7 into the space A and the bucket on the tube '7 supports the water as the bucket 14 approaches it so that the water is discharged under the valve 25 which is thereby lifted and the Water enters the area D.
It will be noted that the space C is the full capacity of the diameter of the casing 1, less the space required for the stationary tube 7, so that on the down'stroke the water in the space C is discharged in that amount less the space occupied by the tube as compared with what the upper bucket 14 discharges on the up stroke. The relief valve 20 can be quickly closed or opened, as will be noted from the construction employed.
When the cylinder is descending, the water is driven out of the space below the cylinder and out of the cylinder top with fluid in the cylinder that is also driven out of the top of the cylinder.
It will be understood that any type of valve mechanism may be used as I have only shown a typical form.
It will be understood that I desire to comprehend within my invention such modifications as may be clearly embraced within the scope of my claims and invention.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is: Y
