Abstract
1501011 Friction dampers LORD CORP 21 Jan 1975 2550/75 Heading F2E A friction damper comprising a housing 3, a bar 17 reciprocable relative to the housing 3, and friction shoes 25 held in contact with the bar 17 by a spring 35 and having freedom to move through a limited distance a, b, along the axis of the bar 17, is characterized by control means 40 which act to reduce the load applied by the spring 35 on the return stroke only of the bar 17. The control means 40 may be in the form of either pivoting arms 41 as in Fig. 1 and Figs. 2 to 7 (not shown), or spheres or cylinders 98 rolling on inclines 101 as in Figs. 9 and 10 (not shown). There may be a single bar 17 with a pair of friction shoes 25 with parallel friction surfaces 23, 27 as in Fig. 1 or with wedge-shaped faces 23, 27 as in Fig. 6 (not shown). Alternatively there may be two connected bars 17a, 17b with two single-faced shoes and one double-faced shoe. Spring return may be provided by a coilspring 49, Fig. 1, or a convolutely wound constant force return spring 65, Fig. 7 (not shown). The claims also include the possibility of the shoes being sprung-loaded against the housing rather than the bar.
