Abstract: 628,329. Road-vehicle spring suspensions. FEDDEN, Ltd., R., SENKOWSKI, A., LAMBURN, A. S., SPENCER MOULTON & CO., Ltd., G., and MOULTON, A. E. Nov. 1, 1946, No. 32426. [Classes 108 (ii) and 108 (iii)] Means for adjusting and setting the angular relationship of one element to another coaxial element whilst under the torsional stress of an elastic element tending to restore the coaxial elements to a position of zero relative angular deflection, comprises a flange member on each of the coaxial elements mutually aligned and each provided with a series of holes, means being provided to rotate one of the flanges relative to the other to give the required angular relationship, a bolt or like member being passed through the registering holes in the flanges to secure the elements in the adjusted position. The invention is shown in Fig. 3 applied to the vehicle wheel suspension described in Specification 628,328, in which an arm 14 carrying a road wheel at its outer end, is connected with the inner rigid tubular element 11 of a rubber bush type mounting, the concentric outer rigid tubular member (not shown) of which is secured rigidly to the vehicle chassis. The arm 14 at its inner end has an inwardly directed flange 15 having a central aperture into which fits the end portion of the element 11. An outwardlydirected flange 13 formed near the same end of the element 11 has a series of circumferentially-spaced holes 17 arranged at the same radius as a similar series of holes 17<SP>1</SP> on the flanges 15. Three bolts 25 pass through respective pairs of holes on the two flanges. Brackets 18, 21 integral respectively with the flanges 13, 15, are relatively movable by an associated bolt 20 and nut 24 to vary the angular setting of the flanges when the bolts 25 have been removed and a nut-and-bolt 26 passing through slots 22 in the flanges, have been slackened off. The number of holes 17 differs from the number of holes 17<SP>1</SP> to enable a vernier adjustment to be obtained. The invention is also applied to the resilient mounting described in Specification 628,330, in which an intermediate tubular rigid member 38, 39, Fig. 4, is common to two rubber bush-type mountings 36, 37, the outer tubular rigid elements 34, 35 of each of which are respectively secured rigidly to the supporting and supported members (not shown). The intermediate member is divided into two sections 38 39, angularly adjustable relative to each other by means of a hand tool, Fig. 6. Flanges 40, 41 integral respectively with the sections 38, 39 have a series of holes and clamping bolts 44, similar to those associated with the flanges 13, 15 of Fig. 3. The periphery of each flange is formed with serrations 45 which are engaged by jaws 28,29 of the hand tool. The jaws are staggered so that each engages the respective flanges which may be relatively rotated by means of a nut and bolt 32, 32a connecting the jaws. In a modified arrangement (Fig. 5, not shown) the flanges 40, 41 are spaced apart by an intermediate annular member and the bolts 44 are replaced by set screws securing the flanges to the intermediate member. The periphery of each flange is'turned over to embrace the intermediate member so that the serrations 45 extend axially instead of radially.
