ABSTRACT:
An apparatus for regulating tension by the compression of a yieldingly resisting core includes a compressible core, a collapsible modifier arranged in the core and a force transmitting or compressive member which receives a tension that is to be regulated and in response thereto applied a compressive force to the core. The core and modifier combine to initially generate a force in opposition to the compressive force applied to them, and the opposition force as applied to the compressive member causes the apparatus to develop a force in opposition to the applied tension. The modifier also aids the applied tension as the core is flattened.
