430,918. Indiarubber &c. springs. LORD, H. C., 36, Penn Building, Erie, Pennsylvania, U.S.A. Dec. 27, 1933, No. 36405. [Class 108 (iii)] [See also Groups XXXI and XXV] In a mounting for automobile engines and like vibrating bodies, of the type comprising pivotal link members between the engine, &c., and its support, the link members are provided at one or both ends with cushions of rubber or like material adapted yieldingly to resist through shear distortions the endwise thrusts of the links. In the form shown in Fig. 5, the upper end of the link is connected to the engine bracket 4<a> through a rubber cushion 8 of the cylindrical-bush type, and the joint at the lower end comprises a stud 19 secured to a cross member 18 of the chassis. A rubber bush 22 is interposed between a sleeve 21 on the stud 19, and a shell 23 pressed into a sleeve 24 formed at the ends of the links 26, so that endwise thrusts are resisted by a shear action on the rubber. The rubber bush 22 is bonded to the parts 21, 23 during vulcanization, so that it is under initial tension. The bush 22 has rounded ends engaging snubber plates 28, which may be so shaped as to provide around the edges a slight clearance, so that the joint responds to swinging action of the link and gives a comparatively free shear action in the vibration range and a more or less quick snubbing action beyond that range. In another form, a link having a cylindrical pivot bush such as 8 at each end is provided with an extension fitted with a rubber bush acting in shear. In the form shown in Fig. 6, similar shear mountings are provided at both ends, and in a further modification, Fig. 7, bushes 22 at both ends are connected by a bolt 35, upper brackets 37 being carried by the chassis, and lower brackets 40 by the engine. In the form shown in Fig. 13, the link comprises lower and upper rubber discs 48, 49 vulcanized between outer plates 54 and inner plates 50, 52 connected respectively to the chassis and the engine, arcuate snubber plates 61, 62, 60, 63 engaging the inner and outer edges of the rubber discs.
