so f

the sucker rod causes the lower portion thereof to oat while tlie upper portion is buckled by the friction ofthe fluid material, and consequently when the sucker rod makes above ten strokes per minute the friction on the lower portion of the sucker rod and on the pump piston of the working barrel retards those parts on the down stroke, so that the stroke of the lower Iportion of the sucker rod is not. tnishedbefore the up stroke occurs, thus producing;` inetlicienti pumping action and causingr crystallization,4

breaking;` and parting of thel sucker rod and wearing of the-pump tubing.

It is evident from the foregoing that.in order to, obtain maximum output: of crude oil from a well with niiuiimnnyloss of volatile oils it is necessary to `et the sucker rod away from' the dense fluid in the center of the column. y

An object of mv invention is Ato avoid these difficulties. This l do by practically .dividing the liquid material .being pumped into a plurality of eolnmnsfthe periineters of which are adjacent the sticker rod-as well as adJaoent. the pump tubing' and to surround tlie same with an unbroken gas-way.4 .extending entirely around the` sucker-rod `from top to bottom of the pumptubin v so that during` the pumpingl operation t. ere

' may be a constant uptlow of gas and liquid in a series of practically, straight columns extending from bottoni to top of thel tubing, with a minimum deflection of the fluids from a'. straighty course ah any point, and to minimize the number of pl: ces where such slight', deflections of the il iid i'na occur.

And such straight. columns olif liqui passing' upward in a straight course hold'thefsuckerrod in the center of t hei pumltiV ltubing,r against:

villa-ation, rotation, hiicklin and bending and from contact with tho pumpI tubing. lly thus dividing the oil that is being pumped int.o a'plurality yof columns, the eavy material in each of the columns gravitates to the center of its column and away from the sucker rod and. from the pump tubing so that the gas and lighter liquid material contact with the sucker rod on the down stroke, as well as with the pump tubing on the up stroke, and the friction is donel away with and the consequent tendencyl to buckle and break is avoided, thus permitting the pump to be run at', a higher speed with greater output.

Further objects and advantages may appear in the snbjoined detail description.`

The accompanying drawings illustrate the invention.

The pump piston and standing'valve are shown intact inside the pump tubing, a portion of which is omitted to avoid confusion.

Fig. 4 is .a cross section on line a", Figs. 1 and Fig. 5 is a perspective View of a welding member havin a different form of welding shank than t at shownv in Figs. 1, 2 and 3. Fig. 6 is a cross section of a ribbed sucker rod having a body fitting the welding member shown in Fig. 5, and in place in a pump tubing.

,The pumping apparatus comprises puni i tubing 1 of the usual construction provideld internally with a sucker rod 9 preferably constructed of separable seetions'p; each of which is formed of three members, a ribbed or bladed member or body 4, of compara--` tively' greatI lengt-h, as for instance, twenty feet, more or less, and of slightly less dialnevterthan the pump tubing; and welding'end members 5, 6, that are each composed of a male or female threaded cou ling 7 or 8,

respectively, of rless diameter t an the body I 4, and intermediate Awrench seats 9 referably of square cross section,`and rib d or bladed welding Shanks 10 that correspond with and are fastened to the body 4 by suitable means as the electric weld a,' so thatthe sticker rod is practically of uniform ribbed cross section throughout its entire length.

The ribbed body 4 and ribbed Shanks 10 are practically Y or X-shaped accbrding as their radial blades, foi'min longitudinal partitions ll'in `the pump tii ing, are three' or four in number, but it is understood that. the number of such partitions may be' inre or less as desired. i

The partitions l1 stillen the sucker rod lengthwise andat the same time ractielly divide 'the pump tubing into a p urality of pumping chambers, channels or passages 12, eachof which is of eater cross-sectional area 'thatthe bladed ody 4 so as to form between each two adjacentl partitions .during the pumping operation, independent co1- umns of liquid material, not shown; and the partitions further provide a seat' for a wrench such as shown, described and claimed in my cofpending application for pump roe-neas et fitting, tiled June 20, 1910, Serial Number 568,033, `and in which oppositely arranged Wrench jaws are provided-Withrslots to engage V a ribbed sucker rod. i

The lowerend of the sucker rod 2 isypro-l..

v ided with a suitablefpiston i3 of any. desired construction and the pump 'tubing' l vmay be provided internally belen7 the ypiston llongitudinal passage to I another clearance space 1s free from any suelterrody 13 with a standing valvele' of any desired forrn. Y l.

Inpractice, the diameter of thev sucker rod is substantially the sarnea'sbut less than' the diameterv of thev pump tubing, thesu'cker rod `and the pump tubing being preferably of such relative proportions that there. isI but slight clearance between the Walls oit lthe tubin and the' edges of the partitions, so that of the tubing and yet'the spaeetis minimized through which liquid may pass troni one and such parts along ythe entire length of the sucker rod, so that the action of the sucker rod willf the inertia of the oil in the pipe to mini- 4columns that are parel mize the tendency of the rod or the sections thereof 4to relatively rotate such rota-- tion can only be effected by p iactf" ily rc tat/ing the entire column of oil or other terial surrounding the portion of the rod that tends to turn. The advantages of thi"I construction and arrangement in this re spect are maximized in the ease or thick and heavy crude oil carrying sand or other solids, and the tendency te unseren' -t the joints is minimized.

In the form shown in rigs. l to '4, inelusive, there are four, and in Figs. 5 and 6, there are three straight 'radially disposed longitudinal partitions, ribs or blades which have n0 radial pro]ections to iinpinge against theoil and which extend nearly but not quite to the walls of' the pump tubinff,

thus forming four or three divisions the tubing, as the case may be, to conine the liquid 4in a plurality of straight angular l'el with. the axis' of the tubing, thus tending to hold the sucker rod against vibration as well. as against buckling and rotation, and furthermore, the strength, rigidity and channel space are :nairirnized,l and the weight and the tri ional resistance against the material to be puni are minimized.

epart'itions-Wiil not touch-.the walls' It is thus seen that I have provided in a pumping apparatus, the combination With the puinp tubing of means to divide the inp terior of the pump tubing' into a plurality vof lpuu'iping chainblersextending lengthwise of therod between the' joints'thereof, and

that the cross-sectional area of eachjointlis .L minimized so that the liquid may flowtreely," y

along the tubing; that the couplings atftlie jointsl cannot corne into conta'ctlwith the tubingorbecorne Worn th'erebyiyand :that

tubing is InininiiZed.,l Y i Itis thus seen thatthe puinp tubing and the ,trictionof the li'lqu'id ou the rod and.'
