Patent ID: 7533557

Claim:
A high-speed tensile test machine comprising: a weight located on a vertical track, two L-levers, said L-levers having a horizontal arm and an essentially vertical arm, said L-levers positioned below and on each side of said weight so said weight pushes said horizontal arms when said weight is dropped, said L-levers having a pivot point located on said horizontal arm, said L-lever being connected to a base at said pivot point; two cables, connected to said essentially vertical arms of said L-levers, said cables being directed around a pulley and connected to shuttles located on a horizontal track; at least one load cell in connections with said shuttles, wherein said load cell is connected to a grip configured to hold a sample to be tested; and a device configured to measure the stress-strain behavior of said sample, wherein when said weight is dropped on said vertical track, said weight pushes downward on said horizontal arm of said L-levers, which pivot about said pivot point, which causes said cables to pull on said shuttles, which move in an outward direction.
