Latest Patents

Fernstrom's latest patents include a "Hand held rotary machine tool with vibration insulating means." This innovative tool is designed for grinding and similar operations. It features an outer housing that contains a pneumatic vane motor, which rotates a tool-carrying spindle. The motor is supported by a resilient O-ring at the front end, absorbing radial vibrations during operation. Additionally, a conical thrust ball bearing transfers axial loads to the housing without compromising the radial resiliency provided by the O-ring. At the rear end, the motor is supported by a non-resilient O-ring, allowing for pendular movement when exposed to vibrations.

Another significant patent is the "Rotary pneumatic tool with vibration absorbing means." This tool comprises a housing and a motor assembly that includes a pneumatic motor for rotating an output shaft. The vibration-absorbing mounting means supports and insulates the motor assembly relative to the housing. It features a resilient connection piece that secures the motor assembly axially and interconnects air passages, enabling communication of pressure air to and from the pneumatic motor.
