PUMP FOR WELLS- Specification of Letters Patent.

Patented May 8, 1906.

Application filed June 2, 1905- Serial No. 263,462.

To all whom it may concern.-

Be it known that I, ARTHUR N. ELLIs, a citizen of Great Britain, residing at San Bernardi'no, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Pumps for Wells, of which the following is a specification.

This invention involves improvements in that type of pumps designed particularly for elevating liquids in oil or like wells and embodying a S111 le or plurality of water wheels or lpropellers or discharging liquid from the we The invention embodies, primarily, a novel form of propeller, a single one or a number of which are carried by a suitable drive-shaft arranged in the well-tubing, and, further, the invention resides in special means for lubricatin the drive shaft, in special bearings there or, and in the provision of means for protecting the bearings from sand, grit or similar foreign matter which would otherwise grind out the bearings for the shaft, giving rise to disadvantages which will be obvious to those versed in the art to which the invention a ertains.

For a ful escription of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efl'ectin the result reference is to be had to the fol owing description and accompanying drawings, in which Figure 1 is a vertical sectional view of a pump embodying one adaptation of the inventlon, the mechanism being shown arranged in the well-tubing in operatin order. Fi 2 is a top plan view of one of t e prope lers disposed in the well. Fig. 3 is a horizontal sectional view taken on the line X X of Fig. 4 looking upwardl bringing out olearl the arrangement of t e blades of the prope ler. Fi 4 is a vertical sectional view showing a mo 'fied adaptation of the invention, the pump barrel or well-tubing being omitted. Fig. 5 is a side elevation of the bearing member receiving the lower extremity of the shaft of the pump mechanism.

Corresponding and like parts are referred to in the followin descriptlon and indicated in all the views 0% the drawings by the same reference characters.

The use of the invention obviates the necessity for digginga pit, as will be apparent, and in carrying out the invention 1t 1s designed that the pump mechanism be arranged in the well-tubing 1 in the casing of the well, said tubing forming virtually the barrel of the pump in the practical working of the invention. The tubing 1 is provided at its up er end with a suitable lateral discharge 2 or the liquid forced upwardly therein, and the upper extremity of the tubing is closed by a suitable plate 3, above which is a casing 4. The plate 3 is formed with a suitable bearing 5, through which passes the drive-shaft 6, the latter extending the en tire length of the tubing 1 and having the pro eller or propellers 7 substantially attac ed thereto. The shaft 6 will be driven by a ulle 8 or like means operably connecte wit a suitable motor, and this-pulley 8 is preferably arranged in the casing 4 in the construction illustrated in the drawings.

In Fig. 1 of the drawings a single pro eller 7 is carried by the drive-shaft 6 at the ower extremity of the latter, and in this construction it is designed that the drive-shaft 6 be protected throughout its length from the action of the sand or anyforeign matter carried upwardly in the well under the force of the liquid being elevated. For the above purpose it is designed to provide located in the well-tubing 1 a pipe 9, which surrounds or incloses the shaft 6, an this pipe 9 will of course be made in a sui able number of sections, de endent u on the depth of the well and the ength of t e tubing 1. It is necessary to provide said shaft 6 with suitable bearings at intervals in the length of the tubing 1, and for this purpose a number of bearing-brackets, such as indicated at 10, are employed, these brackets embodyin a plurality of arms 10, projecting from a iub portion 10", the latter havin an opening 11 therethrough, forming the bearing for the shaft 6. The bearing-brackets 10 are preferably of somewhat clrcular form, having rim portions 10 externally threaded, so as to be readily connected with the coupling-thimbles 12, by which the various sections of the tubing 1 are secured together, the members 10 being clamped between adjacent ends of the sections of said tubing. The hub portion 10 of each coupling-bracket is formed with oppositely-extendmg threaded ortions 13, and the ends of the sections of t e inner pipe 9 are directl attached to the extended portions 13 a oresaid. The pi e 9 within the tubin 1, which surrounds t e shaft 6, is desi e to receive a suitable lubricant, such as 0' or hard grease, so that the bearing-hub the liqui I space between the pipes ortions 10 of the various brackets 10 will e thoroughly lubricated and such portions of course rotected fully from the action of passing upwardly through the 9 and 1, above de scribed. The shaft 6 passes througha suitable stuffing-box 14 on the plate 3 at the upper end of the well-tubing 1, and the sald shaft also asses through another stuffing-box 15 at the lowermost of the brackets 10, the lower extremity of the shaft 6 passing through the stuffing-box 15 a sufficient distance to admit of read attachmentof the propeller 7 thereto. T e lower extremity of the shaft 6 is reduced, as shown at 6', and received in a transverse bearing member 16, suitably supported at the lowermost end of the tubing 1. The propeller 7 .is made of'special construction and comp central openin 17 in its under side to receive the water or otier liquid and with a plurality of outlet openings or passages 18, extending from the hollow ortion 19 to the upper side of the body of tiib propeller, as shown most clearly intliedrawin s. It will of course be understood that the mist-opening 17 of each pro eller carried by the shaft 6 is'l'arger than sai shaft, so that the propellers at intervals in the length of this shaft will readily receive the liquid-as it is being elevated and propel such liquid upwardly. The propeller 1s thus adapted to receive the water at the bottom thereof and discharge the same at the top, and this is of no small advantage, in that it obviates the necessity for the provision of the bottom casting on the pump, a common cap doing the work effectively. The body of the propeller is formed with a tubular extension 20 at its upper portion, and a set-screw 21, threaded transversely into this extension, is adapted to engage the drive-shaft 6 in order to secure the propeller thereto. The 0 enings or passages 18, leading from the ho low portion 19 of the body of each propeller, curve u wardly and radially thereof, so that the liquld pro elled upwardly by each of the members 7 wi be given a swirhng motion, so as to increase the efiectlveness of the pump to-a maximum. Arranged in the hollow portion of the propeller 7 are aplurality of curved blades 22, a blade being provided for each of the outlet passages or openin s 18 and curved to conform somewhat with t e curvature of itsadjacent passage, as shown clearly in Fi 3 of the drawings. The blades 22 forcib y propel and dischargethe liquid through the passages 18 u ward y into the space between the pipe 9 and the outer tubing 1 of the mechanism.

It will be noted that the hub portions 10 of the bearing-brackets 10 are interposed between various sections of the pi e 9, which will be termed the oil-pi e, fbr the purposes of this description. order that a lution of the pipe 9 and rises a hollow body of disk-like" formation, said body being provided witha bricant may be fed into the uppermost secpass downwardly into the lowermost sections, it is designed that the hub portions 10 of the various brackets 10 be formed with vertical oil-passages 23, and thusoil supplied to the space between the u permost section of the pipe 9 and the shaft 6 y means of the oil-pipe 24, leading through the uppermost section of the pipe 9, will pass downwardly into the lower sections of the pipe,supply1ng the lubricant to the shaft-bear- 1n throughout the length of the shaft 6.

ig. 4, which illustrates a modification of the invention,v shows a construction of the mechanism designed to be used where a plurality of prope dfilip wells in order to elevate the liquid. In t pipe, as shown in 1 but the various bear- -brackets 10 in t e length of the tubing 1 be individually su plied with a lubricant and protected from the action of the sand and grit in the liquid by means of short oilpipes 9, one of said pipes being located between the ad'acent propellers about five feet apart. Thel connect with the hub portionsof brackets 10 in a manner similar to that described with reference to the construction in Fig; 1, and the u per portions of the short pipes Qfiwill be closed by suitable stuffing-boxes 25, ing injury to the bearings for the sha t by the foreign matter carried upwardly by the water or liquid. It will be noted, as shown in Fig. 4, that at points where the couplings 26 are used to connect with sections of the shaft 6 the inclosing oil-pipe section will be enlarged to connect with an enlarged extended hub portion 13 of the adjacent bearingbracket 10. It will be understood that in the construction of Fig. 4 the various short oilpipes 9* will be supplied by branch ipes of themain oil-su ply pi e 24, leading om the u per end of the we to the lowermost port1on thereof.

Having1 thus described the invention, what is claime as new is 1. In a pump for wells of the type described, the combination of a well tubing or pipe, a shaft arranged therein, a Propeller or propellers carried by said sha t, earingrackets for the shaft well-tubing, and oil-pipes surrounding the shaft in the length thereof.

2. In a pump for wells of the type described, the combination of a well tubing or pipe, a shaft arranged therein, a ro eller or propellers carried by said sha earingrackets for the shaft in the length of the well-tubin and oilipes surrounding. the shaft in t e len th tiiereof, and connected with the bearingrackets therefor.

3. In a pump for wells of the type described, a well-tubing, a shaft arranged thereers 7 are necessary in very construction the shaft 6 isnot sur-- rounded throughout its length by an oilower ends of the short pipes 9 revent 1 in the length of the in, a propeller carried by the shaft, bearing therethrough whereby the lubricant in the 10 brackets within the tubing and ceiving pipe surrounding the shaft and com- 5 rising sections connected with the bearingrackets to rotect the bearings thereof from the action offorei n matter elevated with the liquid discharge cm the well, the bearingbrackets being provided with oil-passages provided lubricantwith bearings for the shaft, a lubr1cant-reets in the 1pe may ass to the various brackength of t e shaft. In testimony whereof I afiix my signature in presence of two witnesses.
