Abstract
An apparatus is described for urging the measuring pad of a well logging sonde into engagement with the wall of a borehole. A relatively long primary arm on which the pad is mounted includes an actuator, and is pivotally connected to the body of the well logging sonde by a member extending therefrom. A backup arm is pivotally mounted on the extension member and biased outward from the logging sonde by suitable resilient means. The backup arm also is positively connected to a displacement member associated with the actuator. The primary and backup arms are cooperatively withdrawn into the body of the logging sonde by operation of the actuator. Moreover, the logging sonde is made eccentric in the borehole by suitable resilient means connected between the extension member and the sonde body.
