Publication number: 20220339766Abstract: A fastener-driving tool includes a housing and a workpiece-contacting element movable between a rest position and an activated position. The tool also includes a trigger connected to the housing and movable between a rest position and an activated position, a control valve including an actuating pin, an actuation lever movably connected to the trigger and movable between a rest position and an actuating position adjacent to the actuating pin, and a trigger control mechanism associated with the actuation lever and configured for moving and holding the actuation lever in the actuating position. In a powered mode, the trigger control mechanism causes the-actuation lever to move and remain in the actuating position such that the tool is actuated each time the workpiece-contacting element contacts a workpiece and moves to the activated position causing the actuation lever to contact the actuating pin and initiate an actuation of the tool.Type: ApplicationFiled: July 7, 2022Publication date: October 27, 2022Inventors: Stephen P. Moore, Murray Z. Weinger, Daniel J. Birk, Hanxin Zhao, Ricardo Segura, Ryan L. Francis

Patent number: 10668607Abstract: A combustion-powered fastener-driving tool includes a combustion-powered power source having a combustion chamber, a reciprocating piston and driver blade, and a valve sleeve reciprocable relative to the power source between a rest position and a firing position. The valve sleeve partially defines the combustion chamber. A lockout device is in fluid communication with the combustion power source and includes a reciprocating gas piston connected to a latch in operational proximity to the valve sleeve. The lockout device is configured such that upon combustion in the combustion chamber, gas from the combustion engages the gas piston and moves the latch to an engaged position in which the valve sleeve is prevented from moving to the rest position.Type: GrantFiled: November 4, 2016Date of Patent: June 2, 2020Assignee: Illinois Tool Works Inc.Inventors: Hanxin Zhao, Christopher H. Porth, Stephen P. Moore

Patent number: 10618155Abstract: A fastener-driving tool including a housing having an air connector, at least one of a power storage device and an electrical component associated with the housing and an electric motor assembly associated with the housing. The electric motor assembly includes a fan where air is supplied to the housing through the air connector and moves through the housing and contacts the fan to cause the fan to rotate, rotation of the fan causing the electric motor to generate electricity that is directed to the at least one power storage device and the electrical component.Type: GrantFiled: May 8, 2017Date of Patent: April 14, 2020Assignee: ILLINOIS TOOL WORKS INC.Inventors: Stephen P. Moore, Hanxin Zhao

Patent number: 10335937Abstract: A fastener driving tool including a housing, a cylinder enclosed by the housing, at least one sensor associated with the cylinder and a piston configured to reciprocate within the cylinder and having a driver blade depending therefrom. The tool includes at least one signal generator associated with the piston, where movement of the piston relative to the at least one sensor generates a signal. A controller is configured to receive the signal and indicate a fastening result based on the signal.Type: GrantFiled: June 29, 2016Date of Patent: July 2, 2019Assignee: Illinois Tool Works Inc.Inventors: Stephen P. Moore, Daniel J. Birk

Patent number: 9844864Abstract: A fastener driving tool including a housing enclosing a cylinder having a lower end with a resilient bumper, a return air chamber in communication with the lower end of the cylinder and a piston dimensioned for reciprocation within the cylinder to impact the bumper and having a driver blade depending therefrom. At least one inlet opening is in communication with the return air chamber and at least one outlet opening is disposed in the cylinder and spaced from the at least one inlet opening. The at least outlet opening is in communication with the return air chamber and aligned with the piston so that each outlet opening is closed by the piston to seal the cylinder as the piston impacts the bumper and traps a residual volume of air in the cylinder below the piston to damp impact of the piston upon the bumper.Type: GrantFiled: February 10, 2012Date of Patent: December 19, 2017Assignee: Illinois Tool Works Inc.Inventors: Hanxin Zhao, Stephen P.

Patent number: 9782880Abstract: A fastener-driving tool includes a housing, a workpiece-contacting element movable between a rest position and an activated position, and a trigger movable between a rest position and an activated position. The tool includes an actuation lever movably connected to the trigger and a control valve including an actuating pin and an electromagnet where the actuating pin is movable between a rest position and an activated position. In a powered mode, the electromagnet is energized and attracts the actuation lever to the actuating pin and hold the actuation lever and the actuating pin in respective activated positions such that the tool is actuated each time the workpiece-contacting element contacts a workpiece. In a non-powered mode, the electromagnet is not energized such that the tool is actuated each time the workpiece-contacting element and the trigger are each moved from the rest position to the activated position in a designated sequence.Type: GrantFiled: June 3, 2016Date of Patent: October 10, 2017Assignee: Illinois Tool Works Inc.Inventors: Stephen P.
