Abstract
Abstract 925,613. Energy-absorbing devices. COCKERILL.OUGREE S. A. Sept. 24, 1959 [Oct. 14, 1958], No. 32555/59. Class 103 (1). In an energy-absorbing device for railway vehicles the conventional shockabsorbing device in the form of a buffer is provided with an extension consisting of a tube 2 connected to a plate 1, the tube 2 being formed of hardened steel and having a conical end portion 9, the tube 2 is a push-fit in a tube 3 of very ductile steel and an outer tube 4 secured to the structure of the vehicle surrounds the tube 3 such that when the tube 2 is subjected to sufficient axial stress, it moves, dilating the conical end 10 of the tube 3. As the conical end is distorted kinetic energy is absorbed.
