CLEANING APPARATUS FOR WELLS.

Specificationof Letters Patent.

Patented May 18, 1920.

Application filed July 26, 1919. Serial No. 313,522.

To all whom it may concern:

Be it known that I, GEORGE W. RUSSELL, a citizen of the United States, residing at Berryville, in the county of Carroll and State of Arkansas, have invented certain new and useful Improvements in Cleaning Apparatus for Wells, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in cleaningapparatus for wells and has relation more particularly to a device of this general character specially designed and adapted for use in connection with drilled wells, and it is an object of the invention to provide a novel and improved apparatus of this type including a bucket or bail adapted to be inserted within the well, together with suction means for filling said bail or bucket.

Another object of the invention is to provide a novel and improved apparatus of this general character including a bail or bucket provided in a side wall and adjacent its lower or induction end with a normally closed opening whereby emptying of the bail or bucket is materially facilitated.

An additional object of the invention is to provide a novel and improved apparatus of this general character including a bail or bucket having arranged therein a suction piston and which piston is provided with. a rod extending exteriorly of the bail or bucket and to which is engaged an element for lowering or raising the bail or bucket and which element also operates to impart the desired suction stroke to the piston.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved cleaning apparatus for Wells whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention'may bethe better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein: 1

Figure 1 is a. view partly in elevation and partly in'section of a cleaning apparatus constructed in accordance with an embodiment of my invention.

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary view in perspective illustrating a means for maintaining the rod of the piston in working position.

F ig. 4 is a fragmentary View in perspective of the lower end portion of one of the tines or arms at the inner end portion of the rod or piston.

As disclosed in the accompanying drawings, B denotes an elongated cylindrical bail or bucket having its opposite ends open and having coacting with its lower or induction end an inwardly opening check valve 1 herein disclosed of a flat type. The lower or induction end of the bail or bucket B at diametrically opposed points is provided with recesses 2 constituting entrances within the bail or bucket B. The lower end portion of the bail or bucket B is also provided in a Wall thereof with a relatively large opening 3 having arranged at opposite sides thereof the longitudinally directed guideways 4 with which the door 5 is slidabl engaged and which door serves to norma ly maintain closed the opening 3.

The upper end portion of the bucket or bail B is provided with diametrically opposed outstanding arms disposed in a direction longitudinally of the bail or bucket B and which have their outer extremities closed by the cross head 7 A marginal portion of the head 7 is providedwith a recess or notch 8 closed by the swinging plate 9 carried by the head 7. The marginal portion of the plate 9 is provided with a notch or recess 10 adapted to register with a notch or recess 8 of the cross head 7 to afford an opening through which a piston rod 11 is adapted to have rectilineal movement. The free end portion of the plate 9 is provided with an opening 12 adapted to register an opening 14 in the cross head 7 and insertible through said openings 12 and 14 is a pin 15 or the like for holding the plate 9 in closed or working position. The pin 15 is readily removable so that the plate 9 may be swung to one side to facilitate the desired mounting or the piston rod 11.

The inner end portion of the rod 11 has washers 18 are held in working position by the clamping nuts 19 threaded upon the shanks 17 outwardly of the washers 18. Clamped between the annular members or washers 18 is a leather cup or gasket 20 for contact with the wall of the bucket or bail B.

The members or washers 18 and the cup or gasket 20 constitute a suction piston P and the central open portion of said piston P is closed by the inwardly opening check valve 21 herein disclosed as of a flat type.

The outer portion of the rod 11 is provided with an outstanding annular flange or enlargement 22 which contacts with the cross head 7 or the plate 9 whereby the inward stroke of the piston P is limited and isprevented from passing beyond the upper or inner end of the opening 3.

The outer extremity of the rod 11 is provided with an eye 23 or the like whereby an operating cable 24 or the like may be suitably secured thereto.

In practice when it is desired to cleanse a well, the bucket or bail B islowered therein with the piston P at the limit of its upward movement. The bucket or bail B is lowered until the same rests upon the bottom of the well at which time the piston P is permitted to reach its lowered position as regulated by contact of the flange or enlargement 22.

The check or flat valves 1 and 21 permit the bucket or bail to be lowered without resistance.

The bucket or bail B at the bottom of the well and the piston P in lowered position upward pull upon the rod 11 draws the piston P to the top of the bail or bucket and which movement constitutes a suction stroke drawing within the bucket or bail B the matter within the well to be extracted. Continued pull upon the rod 11 through the instrumentality of the cable 24 or the like results in the extraction of the,bail or bucket B. In order to empty the bail or bucket B the emptying the bail or bucket B when the same contains rock or the like.

It is also to be understood that the cross 7 head 7 is spaced at distance from the adjacent end of the bail or bucket B to permit readily the insertion of the piston P within said bail or bucket B.

From the foregoing description, it is thought to be obvious that a cleaning apparatus for wells constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

An apparatus of the character described comprising a bail open at its ends, means for closing the lower end, a cross head projecting from one end of said bail, the intermediate portion of said cross head having a recess, a plate pivoted to said cross head, said plate having a recess registering with the recess in the cross head, said plate and cross head cooperating to provide a socket, a suction piston mounted within the bail, and a rod for said piston slidably and detachably disposed in said socket.

In testimony whereof I hereunto aflix my signature in the resence of two witnesses. G ORGE W. RUSSELL.
