Abstract

283,362. Wade, H., (Canada British Syndicate, Ltd.). Feb. 23, 1927. Springs, arrangement of.-A vehicle suspension is provided with a vibration damper comprising a pivoted rocker arm, a brake drum and band and means for applying the band to the drum including spring connections between the rocker arm and band and adapted to cause tightening of the band on the drum to an increasing extent in proportion to movement of the arm from a given normal position. In the arrangement shown, the damper is applied to a spring suspension substantially described in Specification 282,242, but it may be used separately with some other form of suspension. The rocker arm 28 forms one arm of a bell crank lever A which is mounted and controlled as described in the abovementioned Specification except that the rebound spring is omitted and the rod 12 acting on the supporting spring 13 is guided through a helical bearing member 21 in a sleeve 17 fixed to the supporting bracket C of the lever A and spring 13. The drum H is fixed to the lever A and the band I is connected at its ends to pins 37, 38 on a lever 29 pivoted on a pin 30 having an eccentric adjustment in the bracket C. The lever 29 is pivoted to a rod 39 which passes through a swivel eye 40 on the arm 28, springs 41, 42 being mounted on the rod between the eye 40 and adjustable abutments 45, 46 at the ends of the rod. Movement of the arm 28 in either direction from its normal position causes the band to be applied to the drum in such a manner that the frictional resistance increases.
