  • Patent number: 6182754
    Abstract: A scraper apparatus for a reciprocating sucker rod for prevention of the wearing of grooves in well tubing. The scraper is formed by a body with two opposed spiral vanes extending 180 degrees around the body and defining flow channels positioned between the spiral vanes. The scraper is secured to the reciprocating sucker rod and is positioned within the well tubing. The well tubing has an inner circumference with the two opposed spiral vanes engaging 360 degrees of the inner circumference of the well tubing while enabling fluids to bypass the body through the flow channels.

  • Patent number: 5941312
    Abstract: A method of fabricating a rod guide. The first step involves providing a sucker rod having an exterior surface with a raised profile. The second step involves providing a split sleeve having at least one segment. The split sleeve has an interior surface with a recessed profile that mates with the raised profile of the sucker rod thereby securing the sleeve against axial movement relative to the sucker rod. The third step involves providing an overlying sleeve that overlies the split sleeve to maintain the split sleeve in mating engagement with the sucker rod.
