Patent number: 9522456Abstract: A method of operating a clamp (100) that includes a first clamping jaw (102), a support element (104) to which the first clamping jaw is attached and a trigger handle (118) pivotably mounted to a clamp body (112). The method includes actuating the trigger handle causing the first clamping jaw to experience incremental motion and varying the incremental motion as a function of a load encountered by the support element by varying an effective lever arm of the trigger handle by moving a fulcrum point into contact or out of contact with the trigger handle based on the load.Type: GrantFiled: March 4, 2014Date of Patent: December 20, 2016Assignee: Irwin Industrial Tool CompanyInventors: Chris W. Cicenas, Charles R. McKean, Thomas M. Chervenak, Anthony B. Fuller

Patent number: 8083164Abstract: A machine for distributing blowing insulation from a bag of compressed blowing insulation is provided. The machine includes a chute having an inlet end configured to receive the bag of compressed blowing insulation. A shredding chamber is associated with the chute. The shredding chamber includes a plurality of shredders configured to shred and pick apart the blowing insulation. The shredding chamber further includes a discharge mechanism mounted for rotation and configured for distributing the blowing insulation into an airstream. The discharge mechanism has a side inlet and includes sealing vane assemblies having vane tips. Rotation of the vane tips forms an arc. The blowing insulation is fed horizontally from the shredding chamber into the side inlet of the discharge mechanism in a manner such that the blowing insulation passes through the arc formed by the rotating vane tips.Type: GrantFiled: February 18, 2010Date of Patent: December 27, 2011Assignee: Owens Corning Fiberglas TechnologyInventors: Michael W. Johnson, Michael E. Evans, Agustin Hernandez, Robert J. O'Leary, Christopher M. Relyea, Brian K. Linstedt, Gregory J. Merz, Charles R. McKean

Patent number: 7712690Abstract: A machine for distributing blowing insulation including a shredding chamber having an outlet end, a plurality of shredders configured to shred and pick apart the blowing insulation, and a discharge mechanism mounted at the outlet end of the shredding chamber and configured for distributing the blowing insulation into an airstream. The discharge mechanism includes housing and a plurality of sealing vane assemblies mounted for rotation. The sealing vane assemblies are configured to seal against the housing as the sealing vane assemblies rotate. The housing includes an eccentric segment extending from the housing. A blower is provided and configured to provide the airstream which flows through the discharge mechanism. The sealing vane assemblies become spaced apart from the housing as the sealing vane assemblies rotate through the eccentric segment.Type: GrantFiled: October 16, 2006Date of Patent: May 11, 2010Assignee: Owens Corning Intellectual Capital, LLCInventors: Michael W. Johnson, Michael E. Evans, Agustin Hernandez, Robert J. O'Leary, Christopher M. Relyea, Brian K. Linstedt, Gregory J. Merz, Charles R. McKean
