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...


A method for reducing reverse shocks to rotating flywheel means of a device for producing movement of a ram toward a tool to produce a relatively heavy impact against said tool retained with said device after impact and wherein said ram is moved toward said tool through engagement of said ram by said rotating flywheel means, said method comprising: causing said rotating flywheel means to engage said ram to drive said ram toward said tool; discontinuing engagement of said flywheel means with said ram prior to said ram striking said tool; and arresting the...
