Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
167 words
A buffer arrangement for absorbing and by friction retarding the live force of a linearly moving body comprising one or more friction members provided with mounting means to be secured to said body, each of said friction members comprising an inner clamping jaw and an outer clamping jaw, spring means urging said jaws towards one another, adjustment means adjusting the spring force of said spring means, each of said jaws being shaped in a manner that forms an opening therebetween adapted for the passage of an elongAted cylindrical element, one or both ends of which are arranged to contact and retard said force, a brake lining within said opening, said adjustment means comprising screws passing through one of said clamping jaws and into the other clamping jaw, a distance pipe placed around each of said screws against which pipes the corresponding screws are tightened and interposed layers between the spring means and the outer clamping jaw to adjust said spring force and provide the desired buffer force.
