LOUISIANA suoxnn none-own Application filed May 24,

This invention relates to new and useful improvements in a sucker rod guide.

One object of the invention is to provide a guide of the character described which may be easily clamped onto the joints, or sections, of a pump sucker rod and which will hold the rod spaced from the pump tubing and thus prevent the wearing and weakening of the rod by friction against said tubing.

Another object of the invention resides in the provision of a sucker rod guide which is of simple construction, may be cheaply and easily produced and easily applied to or detached from the rod.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation, and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings,

wherein Figure 1 shows a vertical sectional view of a pump tubing showing the sucker rod therein equipped with the improved type of guide.

Figure 2 shows a side elevation of the guide.

Figure 3 shows a side elevation taken at right angles to the view shown in Figure 2.

Figure 4 shows a bottom end view of the guide.

Figure 5 shows an upper end view thereof, and Figure 6 shows a cross sectional view taken on the line 66 of Figure 2.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the Figures the numeral 1 designates the pump sucker rod, as a whole. This rod is composed of a plurality of sections 2, united by the joints,

In operation the sucker rod is reciprocated in the pump tubing 4 and during this reciprocation has a tendency to come into frictional contact with the tubing, particularly where the tubing is not straight, as is often the case, and unless protected the rod will become worn and weakened, often causing it to break.

Clamped onto the sections 2, between the 1928. Serial No. 280,191.

joints 3 are; the guides, presentlyto bedescribed. f p "Each guide is: composedof'two longitudinal sections 5 and 6. These sections are c0111- plemental, and are substantially similar excepting as hereinafter pointed out. The .guide is an open cage-like structure for light,- ness and economy of material. -The respective'sections have the flat contacting faces '7, 8, formed with the registering grooves 9, 1O 5 at each end thereof and formingrod bearings at each end of the guide. 'One end of the section 5 is widenedforming a substan tially arcuate flange 11, having a side slot and. transversely aligned mortises 12 one 5 :gether by the respective set screws 15, 15.

' In application to, the rod the section 5 is first applied so as to seat the rod section 2 in 'thegroove 9. The tenon-13 is then seated in 'rs the m'ortises 12 andthe opposing ears 14, 14 then forced together and secured bythe [set screwsl5; The grooves 9, 10 are of such size as :to closely fit therod so that the guide will firmly grip the rod when secured thereon. f &

' J Therguide has the longitudinal, radially extending ribs 16 .thereonwhich ride against the pump tubing, and takethe wear, as the rod is reciprocat'edh While we have shown what we now conas sider the preferred form of the invention it is obvious that mechanical changes may be made therein and equivalents substituted for the parts shown and we reserve the right to make such changes and substitutions fio within the scope of the appended claims.

What we claim is 1. A rod guide formed of two longitudinal sections whose facing sides have registering, longitudinal, end grooves forming rod bear- 05 ings, said sections being provided one with a transverse end mortise and the other with a transverse end tenon adapted to fit into said mortise, said guide having a cage-like construction between said bearings and means i for securing the other ends of said sections together around the rod.

2. A cage like rod guide formed of two longitudinal sections having faces adapted to abut and formed with registering end grooves which form a rod receiving bearing at each end of the guide, one of said sections having a transverse mortise, a transverse tenon carried by the other section adapted to fit into said mortise, lateral registering ears at the other ends of said sections, set screws securing the registering ears together to secure the guide around the pipe, and external ribs on said sections having tapering converging ends.

3. A rod guide composed of two longitudinal complemental sections having fiat contacting faces formed with lengthwise registering grooves forming rod bearings, one end of one section being widened forming an arcuate flange which has a side slot to receive the rod and transversely aligned mortises, one on each side of said slot, a tenon on the corresponding end of the other section extended laterally each way and thus adapted to fit into said mortises, the other ends of said sections having lateral registering ears and means through the ears for securing them together.

4. A rod guide composed of two longitudinal, complemental, sections, said guide being of an open cage like structure, said sections having registering end grooves at each end forming rod bearings, one of the said sections being widened at one end forming a substantially arcuate flange having a side slot and transversely aligned mortises, one on each side of said slot across the inner face of said flange, a transverse tenon extending laterally each way from the corresponding end of the other section shaped to fit into said mortises, lateral registering ears at the other ends of said sections and means for securing said ears together to hold the guide clamped about a rod.

In testimony whereof we have signed our names to this specification.
