12,978. Walton, F. June 17. Motor road vehicles.-The bodies of road vehicles are' mounted upon tubular pneumatic cushions of annular or similar shape, which are arranged endways and are unsupported at their inner peripheries by any rigid connexion. In one form, Fig. 2, the cushions A are arranged above the axle C, being mounted between brackets b, c fixed to the chassis and axle respectively. The axle is connected to the chassis by radius rods c<1>, adjustably secured to the brackets c and pivoted to brackets on the side frames B. Lateral movement of the chassis may be limited by rods E', pivoted at E to the side frames B and connected at the other end to tubes E<2>, which are formed with slots engaging pins E<5> on the axle. The tubes E<2> are provided with springs E<3>, Fig. 6, which bear against blocks E<4> on the pms E<5> and are adjusted by means of screw plugs E<7>, locked in position by screws E<8> passing through lugs on the tubes E'. Emergency springs may comprise cylinders F, hollow plungers F<1>, and springs F<2>, the plungers F<1> being adapted, in case of deflation of the cushion A, to come into contact with plates F<4> extending from brackets F<3> secured to the axle. In another form. Fig. 5, the cushions A are arranged around, although normally out of contact with the axle, being supported by brackets c connected to the axle by bolts. These bolts may be fitted with rubber washers to provide additional resilience. The normal resilience of the cushions A, when arranged in this manner, is supplemented at a predetermined point in their deflexion by the compression of the cushions due to the contact of their inner peripheries with the axle. The emergency opening c<1> may be arranged in a cylinder c<9> on the axle, the plunger c<10> being adapted to contact with a projection b<4> on the bracket b<2> fixed to the frame B. The upper supporting-member b may be arranged to slide in the bricket b<2>. A radius rod pivoted at each end and formed in two parts connected by an adjusting- nut, may be provided. A three-point suspension may be obtained by employing on the front axle only one cushion arranged parallel to the axle. Creasing of the cushion may be prevented by means of a flexible metal ring encircling the inner periphery, or by reinforcing the cushion at the parts likely to be affected. In some cases, the material forming the cushion may be sufficiently stiff and resilient to be operated without inflation. In a modification, the cushions may comprise tubular vessels connected to the chassis and axle somewhat after the manner of the ordinary elliptic or semi elliptic springs. According to the Provisional Specification, the cushions may in some cases be reinforced with a metallic rim externally as well as internally.
