Patent number: 10086473Abstract: An upper housing assembly includes a pivot arm having an upper cam surface adjacent a distal end. A cam follower is coupled to a laser head to move up and down with a laser head. The cam follower exerts a downward force on the upper cam surface during normal operation. Thus, as the pivot arm rotates back and forth, the laser head moves up and down. A assist gas hose can be coupled between the upper housing and the laser head which has a spiral configuration permitting relative axial movement between the upper housing and the laser head. Upon an upward axial force being exerted on the laser head, the cam follower moves upwardly away from the upper cam surface.Type: GrantFiled: May 5, 2014Date of Patent: October 2, 2018Assignee: LASER MECHANISMS, INC.Inventors: Scott Swartzinski, William G.

Patent number: 9547143Abstract: A method and apparatus are disclosed for aligning the coupling an optical laser fiber using an alignment structure. The disclosed alignment structure accepts an optical fiber having a beam and a detection apparatus. According to one aspect of the teachings, the detection apparatus has a tapered form having a circular cross section at one end to match the laser aperture, and a circular cross section at the other end to match the fiber core.Type: GrantFiled: May 9, 2014Date of Patent: January 17, 2017Assignee: LASER MECHANISMS, INC.Inventors: William G. Fredrick, Tom R. Kugler, Dan R. Buckley, Ruchira D. Perera, Gerry F. Hermann, Scott D. Swartzinski, Mark J. Taggart

Patent number: 9267975Abstract: The high speed, high accuracy capacitive gauging system employs an oscillator fed through steep slope filter that is discriminates between very small changes in capacitance even in the presence of electrical noise. During intervals when the probe tip is retracted, the oscillator frequency is calibrated to match the sweet spot in the center of the linear operative region of the steep slope filter. This calibrates the system to overcome the effects of varying temperature and humidity in the manufacturing environment.Type: GrantFiled: March 15, 2013Date of Patent: February 23, 2016Assignee: LASER MECHANISMS, INC.Inventors: Gerald F. Hermann, Daniel R. Buckley, Scott D. Swartzinski

Patent number: 7363796Abstract: A method for cold-forming a nozzle for a laser includes placing a slug or tube of oxygen-free copper into a die. A mandrel is forced into the copper slug or tube. The resultant compressive force causes the copper to cold flow around the mandrel and the die to define an inner shape and an outer dimension of the part.Type: GrantFiled: November 29, 2004Date of Patent: April 29, 2008Assignee: Laser Mechanisms, Inc.Inventor: William G.
