초록

A high impact device, as for producing an impact of 1,000 foot pounds or more, includes a ram which is engageable by a pair of rotating flywheels. The ram may impact a tool, as of a chisel type adapted for demolition purposes, or having a enlarged head for percussion purposes, or other types or purposes. By terminating the engagement of the flywheels with the ram prior to its impact against a tool or similar object, the vibration normally associated with a demolition or percussion device is avoided. Such termination of engagement also reduces reverse sho...
