Abstract
An invention in a rock core testing unit vibrator for generating a vibration at a controlled frequency for coupling to a barrel of a rock core test unit wherein a rock core cutting is jammed. In practice, the generator output is controlled to produce a harmonic or natural resonant frequency of the barrel of sufficient intensity to produce a resonant elastic vibration therein to shake that barrel relative to the rock core cuttings, dislodging the rock core cuttings that then fall therefrom under the urgings of gravity.
