SNAP-0N SUCKER-ROD GUIDE.

Application filed May 1,

This invention'relates to snap-on sucker rod guides.

The general object of the invention is to provide a sucker rod guide which can be economically manufactured and quickly installed.

A specific object of the invention is to provide a flexible member for snapping on a sucker rod to act as a guide therefor.

Anotherobjectof theinvention is to provide a sucker rod uide comprising a piece of metal or other exible material which is arranged in spiral form and is alsoadapted A further object of the invention is to provide a spirally wound sucker .rod guide having means thereon for engaging the sucker rod.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

Fig. 1 is a central sectional-view showing a portion of a well with a pump casing therein having a sucker rod equipped with my invention.

Fig. 2 is a view similar to Fig. 1 on a larger scale.

Fig. 3 is a section on line 3-3 of Fig. 2.

' Fig. 4 is an elevation showin the manner in Cyvhich the guide is arranged a out a sucker r0 Fig. 5.115 a sectional view of the modified form of my invention, and

Fig. 6 is a sectional view showing a further modification of my invention.

Referrin to the drawing by reference characters have shown a well casing at 10. Within this well casing I show a pump casing at 11. A. sucker rod is shown at 12.

The sucker rod guides embodying the features of my invention is shown at 14. This guide is preferably flexible and may be made of metal or other material. My guide is constructed to normally take the position of a spiral, and the upper and lower ends of the spiral if desired may bebent abruptly inwardly as at 15. with the extreme ends 16 pitched toward the center of the spiral so that the edge 17 may bite into the rod 12 to prevent up and down movement of the rod between the rod andguide.

The guide being spirally arranged does not prevent the flow of fluid through the pump casing, but does effectively support the sucker rod. The guide will also provide an 1926. Serial N0. 105,996.

outer edge which as .the rod moves up and down in the well prevents the accumulation of parafline or other solids on the inner wall of the casing. The guide will be of material which is of suflicient softness to cause no injury to the inside of the casing 11 due to the rubbing cont-act. The guide may be provided'with perforations 18 which may be distributed at intervals as desired.

The inner diameter of theguide is preferably slightly less than the outer diameter of the sucker rod so that the resilient properties ofthe guide will maintain it in proper position. The guide will be sprung as shown in Fig. 4 when installing it.

In Fig. 5 the guideis shown as rovided with supports 20 for rollers 21, w ich are adapted to engage the inner wall of the easing 11. These rollers may be used'whenever desired. Y

In Fig. 6 I show a modification of my invention wherein the flexible sucker rod'guide 25 comprises a flexible stri of material such as compressed fibre or ot er substances in which a flexible strip'26 of metal or other material is imbedded. The flexible strip 26 serves to maintain the shape of the" guide while the softer material 25 prevents wear but does not prevent the flow of fluid through the casing 1 From the foregoing description it will be apparent that Ihave provided an economical and effective sucker rod guide which can be quickly installed. My invention also serves as a casing or tubin protector since it properly centers the suc er rod so that the latter remains out of contact with the inner wall of the casing or tubin Having thus descriEed my invention what I claim is: g 1. In combination with a well casing, a. sucker rod movable in said casing and means engaging said casing and said sucker rod to prevent flexing of said rod, said means comprising a strip of material arranged to entirely surround and to engage said rod throughout substantially its entire length.

2. In combination with a well casing having a sucker rod movable therein, a member arranged on said sucker rod and engage Mid 3. In combination. with a sucker rod, aguide comprising a strip of material shaped to surround and engage the sucker rod throughout. its entire length, said guide forming a curved channel in conjunction with the rod.

4. In combination with a. sucker rod, a flexible guide comprising a strip of material bent to spiral form and having portions thereof gripping said sucker rod, the extremity of said strip having an edge bent substantially parallel to the rod to engage the rod.

5. A. sucker rod guide comprising a stri of material bent to form a spiral, the ones of said spiral being bent abruptly inwardly and having the extreme end pitched at a slight angle to the spiral whereby a sharp edge is provided for engaging a sucker rod.

6. A sucker rod guide comprising a strip of material arranged in curved form and having a central aperture adapted to receive a sucker rod, said spiral having a normal signature.

nsaaeee central diameter slightly less than the diameter of the sucker rod which it is ada ted to engage, whereby there will be tight iit'io tional engagement between the guide and rod.

7.111 combination with a well easing a sucker rod movable in said casing and guide means engaging said casing and said sucker rod, said guide means engaging the periphery of the rod and having a spirally arranged wall therein.

8. In combination with a well casing having a sucker rod movable therein, a member arranged on said sucker rod and engaging said casing. said member comprising a strip of fiat flexible material rectangular in cross section. said strip being bent so that one narrow edge of the strip engages said casing while the other narrow edge engages said rod to hold the strip in position.

I In testimony whereof, I hereunto atfix my RALPH a. nosrio.
