610,955. Resilient mountings. SILENTBLOC, Ltd., and HUTTON, P. C. April 15, 1946, No. 11575. [Class 108 (iii)] In a resilient bearing of the kind comprising a bushing of resilient material interposed and radially compressed between inner and outer members, the resilient bushing has an outwardly-extending flange at each end and is formed in its undistorted state with a circumferential groove at the point where the part to be radially compressed adjoins the flange or each flange. In the mounting shown in Fig. 5, the bushing before assembly is formed as shown in Fig. 6 with flange portions G<SP>1</SP> having the same diameter and axial length as the flanges of the assembled mounting. A central portion G of greater diameter and less axial length than that of the corresponding portion of the assembled mounting, is bounded at each end by a radial slot G<SP>3</SP>, the diameter of the base of which is equal to the inner diameter of the outer rigid mounting member E (Fig. 5). On assembly, the bushing, Fig. 6, is forced into the outer member E until the inner edge of the rearmost flange G<SP>1</SP> abuts the respective flange El of the member E. The inner member B is then inserted in the bushing by means of a tapered leader member and the resultant elongation of the portion G causes the whole of the foremost flange G<SP>1</SP> to emerge from the other end of the member E. The member E is then mounted in a split-socket H of a mounted member such as a spring eye. In an alternative construction (Figs. 1 to 4, not shown), the mounting is split axially and each half is inserted from either end of a socket which is not of split form. In a further construction in which the socket is not split (Fig. 7, not shown), the mounting is similar to the construction of Fig. 5, but the member E is of greater radial thickness than that of the flanges G<SP>1</SP> and its outer diameter is uniform so that the assembled mounting may be pressed into a solid spring eye. A press tool for this operation bears on the annular space between the outer diameters of the flange and member E. The flange and compressed part of the bushing may be of the same external diameter before assembly. Specifications 527,780 and 689,321 are referred to.
