Abstract
In a force amplifier, supporting members extend between a pressure plate and a countersupport plate. At each plate the supporting members bear against end bolts and intermediate the plates the support members bear against joint bolts. A spreader bolt extends through the countersupport plate and has a spreader head located between the joint bolts. The surfaces of the spreader bolt contacting the joint bolts are concavely shaped.
