To al wftom may concern:

Be it known that l, WILLIAM L. Basen, a citizen of the United States, and resident of Fort Mclavett, in the county of Menard and State ot Texas, have invented certain new and useful improvements in ntirio tion Hollow-Tube Sucker-Rods for Deep Wells, of which the Jollowimg is a specification.

The `presenut invention relates to sucker rods for pumping oil, water and other liquids from deep wells, and aims to provide novel and improved yet simple and inexpensive means for coupling the tubular sections of the sucker rod together and guiding said rod with little or no tric-tion in the well casing or tuba The invention has for its object the provision of a simple and effective device for coupling the tubular sections of the sucker rod together, and provided with simple and efficient anti-friction means for guiding the sucker rod for reciprocation in the Well.

This invention is an improvement over the devicesy shown in my former Patents Nos. leraar, 484,947, nales, 712,487, 712,488, 712,901, and 735,200.

With the foregoing and other ohiects 1n view, which will be apparent as the invention is better understood, the saine resides in the construction and arrangement of parts hereinafter described and claimed, 1t being understood that changes Within the Scope of what is claimed can be made Without departing from the spirit of the inverr tiert The invention is illustrated. in the accompanying drawing, Whereiua-4 Figure is longitudinal coupling and roller guide.

Fig. 2 ,is a side elevation thereof.

the drawing` the numeral l designates the casing or tube oi a deep Well, and the numerals Z and 3 designate two tubular sections of the sucker rod which reciprocates in the casing l for pumping the oil, Water or other liquid as usual.

The coupling is designated. generally by the numeral fl, and embodies a vertical tubular or hollow body 5 of suitable material and of larger diameter than the sucker rod and slightly less diameter than the casing l. The upper and lower ends of the bodyT 5 are contracted, as at 6, to provide the reduced open ends or bosses 'Y which are internally section or the screw threaded for the threaded reception rarement oet, tra, reist of the adjacent ends of the sucker rods sections 2 and 3, thus coupling said sections together. l,

Disposed within the bodv 5 of the coupling are a plurality of verticallyv spacedv guide rollers 8, there being two as illustrated v although morey can be used. rlhese rollers are arranged in different vertical planes at' an angle with one another, and said rollers are mounted on the axles or pins 9 havingV thereof. -The Walls of the bodyT 5 are provided With longitudinal slots ll through which the peripheries of the rollers 8 project slightly from the opposite sides of the coupling. The rollers 8 are of' slightly larger diameter than vthe body 5 to project therefrom, but of slightly less diameter than the internal diameter of the Well casing 1,

so that the rollers Will be out of contact with the casing when the sucker rodl is concentric therein.

l/Vith the present construction, or tubular sucker rod sections have their ends opening into the coupler which is tubular or hollow, and this permits of the liquid flowing through the sucker rod and Acoupler as Well as on the exterior thereof, thus increasing the capacity of the pump to the maximum, because'oi1 the maximum cross sectional area of the column of liquid Within and Without the sucker rod..

'lhe sucker rod is at all times kept at the center ol the casing by the rollers, for should the sucker rod tend to shift laterally toward. any side, one or both of the rollers will con. tact with the easing. Said rollers will reduce friction between the; sucker rod and casing. The axles of the rollers can be of comparatively large diameter, so as to insure great strength and wearin device there-fore provides tor economy by increasing .the capacity of the pump and decreasing wear and tear. Furthermore, the hollow formation of the; coupler 'and 'slots prevents the accumulation of sand, grit and the like adjacent to the rollers, thus keeping the device clear.

lt is preferable to have lock nuts 19011 the rod sections Q'and 3 to bind against the ends of the coupler and avoid loosening o the parta ability. rlhis the hollow. 'l

Having thus described the invention, what is claimed 'as new is:

1. A sucker rod guide andl coupling e1nbodying a slotted vertical body having means to connect'the spaced ends of tubular sucker rod'sections, said body being hollow for permitting the flow of liquid between said sucker rod sections and rollers mounted in the body in different vertical planes at an angle with one another and projecting outwardly through the slots of the body.

2. A sucker rodliguide and coupling yenibodying a hollow"y yer-tical bodyv having side slots and open ends for the attachment ot' spaced tubular sucker rod sections to connectth In and permit the iow of liquid therein, a-Iid` rollers mounted within the body ie different vertical lanes at an angle with one another andp projecting outwardly through said slots from the sides of the body.

3. A sucker rod guide and coupling e1n bodying a hollow body having slotted sides yand open ends for the attachment of the ends of spaced tubular sucker rod sections to connect them' and permit the low` of liquid therein, and anti-friction guiding means mounted within the body and-project ing from the. sides thereof through the slots.

4. A sucker rod guide and coupling .eme bodying a hollow body having slots in its sides and reduced open ends for the atta jh ment of spaced tubular sucker rodsections to connect them and permit the flow ot.-

liquid therein, and rollers mounted within the body and projecting'from the sides thereof through said slots.

5. A sucker rod guide and coupling ernbodying a hollow vertical body having open ends forthe attachment of spaced tubular sucker rod sections to connect them and pervmittheow of liquid therein, vertically i-,eemse spaced rollers Within the body in diierent vertical planes at an angle with one another, the sides oi the body having slots from which the rollers project, and axles for the rollers supported by the walls of the body.

6. The. combination with spaced tubular sucker rod sections. of a hollow coupling connecting them for the flow of liquid therein and having side slots, and anti.- t'riction means housed within the coupling and extending out through the slots to guide it in the well.

T. The combination with spaced tubular sucker rod sections, of a hollow cou ling connecting them for the flow of liquid t erein and having' side slots, andI vertically' spaced antbfriction guiding means mounted within the coupling and projecting from the sides thereof 'through the slots.

8. The combination with spaced tubular sucker rod sections, of a coupling embodying a hollow body having slotted sides and open,ends attached to said sections to oonnect-them and permit the flow of liquid therein, and rollers mounted within thebody and projecting from the sides thereof through the slots.

9. 'lhc combination with spaced tubular sucker rod sections, of a coupling therefor embodying a hollow body of larger diameter n than said sections and having reduced open ends attached to the adjacent ends of said sections to connect. them for the flow of liquid therein, rollers within the body, the

walls of the body having slots through which said'rollers project, and axles for the rollers supported by said walls.

' In testimony whereof set my hand this 18th day of February, 1918.
