Application filed January 8, 1929, Serial No. 331,040.

This invention relates to pump rod guides, the primary object being to provide a guide for pump rods or sucker rods used in deep Wells such as oil wells, the guide being cffective in preventing the sucker rods from Whipping and thereby parting.

It is well known that in the oil fields, the sucker rods made up of a plurality of lengths or sections frequently break due to the whipping action caused by the length of the string of rods and the back-lash caused by the change or movement at the end of each stroke. When the string of rods breaks, the well must be shut down for repairs. This interrupts the production of the well. By providing guides at suitable intervals on the stringand of approximately the diameter of the tubing, the Whipping action is prevented with the result that the pump is maintained in constant operation over a longer period than is possible without the guides. Prior to my invention, guides have been employed but difficulty has been encountered in keeping the guides in position on the rods so my invention relates particularly to a lock or fastening means for holding the guides in fixed positions on the string.

The novelty of the invention will be appars ent by reference to the following description in connection with the accompanying drawings in which:

Fig. 1 is a perspective view of a rod guide with the parts in open position ready to be applied to the rod. 1

Fig. 2 is a perspective view of a rod guide applied and Fig. 3 is a detailed View of the guide rod lock.

The rod guide pro er is shown as consisting of a plurality o cylindrical bushings 1 and 2 having oppositely disposed rod receiving slots 3 and 4t and longitudinal grooves or slots 5 and 6 on their outer portions, the groove 5, when the members 1 and 2 are in place, registering with the slot 4 and the groove 6 registering with the slot 3 so that passageways are provided for the oil or liquid to pass up through the tubing. The members 1 and 2 are pivotally supported on a longitudinal spring rod 7 carrying at item- 8 and in the member 9 to bind on the rod spectiveends-the locks 8 and 9'; The locks -8 and '9 each consists of a substantially u-shaped malleable casting, eachhaving an" inclined outer face 10. That is, the outer face-of each-lockis slightly at a transverse angleand "each-member 8 and '9 -'is secured to the end of therod bya head 1'1 on therod; The members 1 and- 2 can belsw-unginoppositeqdirecti ons to open up'a space to receive the -rod12 in the slots Sande: as shown in; Figure-'1.

' The member 8 and the member 9 are preferably constructed of a bronze alloy and the members 1 and 2 are constructed of a tough material which will not splinter or shatter, such as bakelite. I have found in actual practice that where wood is used for con- 'structing the members 1 and 2 that the woodshatters and splits and that it gets into-the valves of the pump with resultant dis advantages but by employing bakelite, so

formica, celeron or similar material, the

parts wear without clogging up the valves of the pump so Irecommend this material as an important part of the invention.

l/Vith a device constructed in accordance 9 with my invention, the rod guide will be held in its fixed position for an indefinite period of time. It cannot be jarred loose and the disadvantages present in rod guides in which wood is used is entirelyeliminated. It is to V be understood, of course, that the guides are of slightly less diameter than the tubing in y i Y :vvhich they Work sosome oil could flow past the guides, but by providing grooves 5 and 1 5 6 in line withthe slots 4 and. 3 respectively,

relief passageays are provided which will ,permitof adequate fiow of the oil through V the tubing to the top of the Well. i What I claim and desire to secure by Let- 10 1 s Patent is:
