Abstract
The handle of a tie tamper is connected to its vibration generating motor, to which a beater is rigidly fixed to be vibrated thereby, by a combination of a Neidhart damper fixed to one end of the handle, a shackle-link pair fixed at one end to the square shaft of the damper, and an arcuate leaf spring pin-connected at its one end to the link pair and at its other end to the motor and by a two-bar linkage connected at its two ends via Neidhart dampers respectively to an intermediate part of the handle and to the motor, and a balance weight is provided at the pin joint between the two links of the two-bar linkage. This construction greatly reduces the vibration transmitted from the motor to the handle.
