Abstract

816,089. Rubber compression springs. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI, S. A. G. A. S.p. A. June 12, 1957 [July 7, 1956], No. 18591/57. Class 108(3) In a rubber spring comprising a pile of circular coaxial rings 1 of resilient rubber alternating with annular metal spacer members 2, the rings 1, are shaped as shown in cross-section so that the stiffness of the spring increases as the spring is compressed. Rib 3 and groove 4 co-operate with. grooves and ribs in the spacer members to centre the rings relative to ther spacers. Other suitable cross sectional shapes for the rubber rings are described and illustrated.
