摘要： A drive shoe (10) for penetrating soil is a larger size than a conductor pipe (11) and connected to the bottom section of the conductor pipe. An exterior band (40) is mounted on the outer diameter and proximate the lower end of the drive shoe. Teeth (28) are spaced at a predetermined interval and extending form and forming the bottom of the drive shoe to enhance penetration into earth formations. The teeth (28) are formed by cutting a beveled section such that the bevel is angled from the drive shoe outer surface towards the drive shoe inner surface. The drive shoe may also have an inner band (41) mounted on the inner surface to further compress the soil away form the interior surface of the drive shoe.

摘要： A shoulder-type elevator is described. The elevator (10) has a frame (12) that supports a ring-shaped body (16) having an inwardly tapered interior surface. The body (16) is configured to receive a length of pipe a collar (C) with an outwardly protruding shoulder. A timing ring (42) supports a plurality of shoes (40) curvilinearly arrayed around the interior surface of the body (16). A set of timing ring cylinders with extendable and retractable piston rods (32) provide powered reciprocal movement of the over a desired range, and thereby powered reciprocal movement of the shoes (40), radially inward and outward around and below the shoulder of the pipe collar (C) within the interior of the ring-shaped body (16). Compression springs (54) mounted around each of the timing ring cylinder piston rods (40) provide an upward bias to the timing ring (42) at the end of its powered range of downward movement. The position of the shoes (40) within the ring-shaped body is configured so that the pipe collar will bear on the shoes to compress the upwardly biased compression springs (54) on the piston rods (32) of the timing ring cylinders.

摘要： An elevator apparatus (10) for manipulating well bore tubing (12) includes a circular body (16) having a top (18) and a central cavity (26) around a body axis (28). The cavity (26) has a diameter allowing the collar portion (14) of the tubing (12) to pass longitudinally therethrough. A plurality of cavity restricting members (36) above the body (16), supported on and spaced apart around the top (18) of the body (16), have proximal (38) and distal portions (40) in respect to the cavity (26). One or more actuators (60) are operatively associated with the petal plates (36) for moving the proximal portion (38) of each cavity restricting member (36) into the cavity (26) an extent sufficient, in combination with the other cavity restricting members (36) so moved, to prevent passage of the collar portion (14) of the tubing (12) through the cavity (26), thereby to hold the tubing (12) with the elevator (10).
