Abstract
713,453. Tamping machines. LANG, A. Aug. 28, 1951 [Aug. 29, 1950], No. 20252/51. Class 124 A tamping device comprises a wheeled machine frame, an internal combustion ram unit mounted in a ram guiding frame slidable relative to the machine frame and having a stop device against which the ram unit strikes during its upward movement to cause the frame to rise, and an impact plate, having a pivotally attached tamping plate, mounted at the lower end of the ram guiding frame to receive the blows of the ram. As shown, a ram unit 1 is mounted in a frame 2 having guide channels 2a engaging rollers 9 carried by a wheeled machine frame 8. The frame 2 carries at its lower end an impact plate 4 connected to a tamping plate 6 by a ball joint 5 (Fig. 5), and at its upper end impact pins 11 which engage corresponding pins 10 on the ram unit when the latter rises causing the guiding frame, impact plate and tamping plate to rise. On its downward movement the ram strikes the impact plate, the ball joint allowing the tamping plate to adjust itself according to irregularities in the ground. A latch 15 operated by a Bowden cable may be arranged to intercept the ram when at the top of its stroke and put the device out of operation. The downward stroke of the ram may be used, in conjunction with a ratchet and pinion, to tension springs which move the wheels to advance the device. A separate motor may also be used to move the device. The frame and handles may be adjustable for ease in handling and for transporting the device to and from its working site.
