Abstract

763,858. Friction-damped coil spring units. SYMINGTON-GOULD CORPORATION. July 27, 1954 [Aug. 24, 1953], No. 21877/54. Class 108(3). The invention relates to means for frictionally damping a coiled spring 9, comprising a sleeve 2 into which extend a plurality of shoes 5, a plurality of coil springs 10 each acting against all of the shoes and transversely disposed at any of a plurality of angles. According to the invention, a plurality of seat groups is provided in each of the shoes, each selectively seating one of the springs 10 at any one of the angles, and including a circular surface 14, and a pair of cylindrical segments 16 interrupting the surface 14 and having spaced planar base portions 19 disposed obliquely to each other and to the surface 14 and extending on opposite sides of the surface 14. Each spring 10 bears at one end on the whole of the surface 14 of one of the shoes and bears with its other end on adjacent surfaces 19 of the other two shoes. Each shoe is formed with a longitudinally extending inner surface, 13 Fig. 3 (not shown) in which are formed cylindrical recesses, the bases of which form the respective surfaces 14. The surface 13 is bounded by longitudinally extending inclined surfaces, which are coplanar with the base portion surfaces 19. A spring cap 15 is disposed between the surfaces 19 and the associated spring end.
