Abstract

682,362. Casing centralizers. BAKER OIL TOOLS, Inc. Dec. 18, 1950, No. 30819/50. Class 85 A device A for centering conduits B and the like in a well bore C has upper and lower longitudinally spaced collars 10, 11 between which extend and to which are attached a plurality of circumferentiaily spaced ribs 12. Each rib is made from a single sheet metal blank and is channel shaped in cross-section with a mid section 13 parallel to the axis of said collars and tapered end sections 14 for securing the mid section to the collars.
