Abstract
A lever action sampler having a body portion, usually tubular, and a pair of opposed end plugs for securing to the two ends of the body to thereby entrap a sample when activated is disclosed. The present invention utilizes a lever pivot assembly for an end plug at its upper portion, a lower end cap pivot assembly at the lower portion, both of which are pivotally secured to the end caps to permit the same to be locked/open for descending, and later closed for encapsulating the sample. The end caps are powered by means of a power spring and power spring cable operating exteriorly of the body, and actuated by means of a lever which cocks the unit into its unlatched and power spring preload functions, and thereafter secures a lanyard to either a rosette or to the sampler itself, and is subsequently fired by means of hitting the end cap of a push rod which release the lanyard or by releasing the lanyard from a rosette. The method contemplates the steps generally as itemized above.
