DEVICE FOR DAMPING OF VIBRATIONS IN WORKPIECES.

Vibration dampers are more efficient when fitted with a supplementary mechanical link through the damper to the cross-slide of the machine tool saddle; their use, however, presents more inconvenience caused by any change of diameter of the workpiece necessitating dimensional adjustment of the damper. In this connection a device was developed, and it was introduced in a number of factories, for damping vibrations in the workpieces, which represents an improvement of the known designs of lever-operated type of vibration dampers. The characteristic feature of the design is the presence of the inclined slot in the lever for the axle of a roller, and of two holes for fitting a dowel which connects the lever with the toolpost.
