    • 574. Pope, R. Jan. 23, 1911, [Convention date]. Vibration dampers. - Relates to means for absorbing the rebound energy of vehicle springs of the kind in which the return movement of the springs following their compression is converted into a forward movement of the vehicle through suitable ratchet gearing operating upon the wheel axle. According to the invention, a ratchet disk, mounted upon a countershaft parallel to the axle, is rotated by the relative movements of the frame and axle, and drives in the rebound direction a ratchet - wheel mounted loosely on the countershaft and geared with the axle. Fig. 2 is a side elevation showing one construction in which the compression of the bearing-spring K causes a rack E connected with the vehicle frame to rotate a pinion F which drives a disk H carrying a pawl H. The pinion F and disk H are mounted on a countershaft C which also carries a wheel G having external teeth gearing with a pinion J on the axle B of the vehicle and internal ratchet teeth with which the pawl H engages. The springs, after compression, are therefore held by the pawl and gradually recover owing to the movement of the wheel G as the car moves forward. When the car moves backwards the pawl is disengaged by a cam H operating upon a tail on the pawl. Fig. 6 shows the wheel G driven by a worm J on the axle, the disk H' being connected with the vehicle frame by links E, E .
