Abstract

A compression tester for resilient objects such as springs and foam articles, including a supporting bed for the object to be tested. A platen is positioned on the object and a driving handle is engaged for forcing the platen into the object. A scale measures the amount of force applied and the distance of movement of the platen into the object is simultaneously indicated. This provides a tester which will determine the force required for depressing a resilient object through a given distance.
