Abstract
Both apparatus and the method is directed to a sampler array carrying a plurality of samplers in which the array has a trip assembly with a plurality of lanyard release pins. One moving member in the assembly contains a pivotal cam which is spring loaded in order to pass a plurality of lanyard release pins in one direction, but to move in the opposite direction and depress the lanyard release pin thereby releasing the lanyard to a preselected sampler for purposes of closing the same and entrapping a sample by the exact sampler desired by the operator at the surface. The method then contemplates counting the degrees of movement of a moving trip wheel having a release cam in one direction in which each sampler lanyard release pin is bypassed, and thereafter reversing the same having the lanyard release pin which is desired to be activated confronts the angled under surface of the lanyard release cam which, when reversed, will depress the lanyard release pin and release the lanyard to close the sampler.
