792,376. Spring wheels. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI S.A.G.A. SOC. PER AZIONI. June 30, 1955 [July 6, 1954], No. 18947/55. Class 144 (1). In a spring wheel wherein the rim 1 and hub 5 are resiliently connected by rubber or like blocks, sectors or rings 6 sandwiched between flanges 2, 3, 4 radiating from the rim and hub, so as to be under combined radial shear and compression when under radial load, torque stresses are also resisted by the rubber blocks under combined shear and compression by providing the blocks or rings 6 with a circumferential section of waved or corrugated form, Fig. 2, to engage in corresponding radially extending corrugations in the faces of rigid metal plates P vulcanized to the blocks and engaged by the flanges. As shown the blocks 6 and the corresponding faces of the flanges are disposed at an angle to the plane of the wheel, the rim comprising either two side flanges 2, 3 embracing a central hub flange 4, Fig. 4, or vice versa, Fig. 5. In either case one or both the side flanges of the hub or rim may be detachably mounted by clamping bolts which may pass through or between the blocks and effect axial pre-compression thereof, or in the construction of Fig. 5, by a coaxial hub nut.
