US Patent:

7163134, Jan 16, 2007

Filed:

Jan 3, 2005

Appl. No.:

11/028450

Inventors:

Larry M. Moeller - Mundelein IL, US
Joseph E. Fabin - Elmwood Park IL, US
James E. Doherty - Barrington IL, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B25C 1/04

US Classification:

227 8, 227 2, 227 10, 227130

Abstract:

A combustion-powered fastener-driving tool includes a combustion-powered power source, a workpiece contact element reciprocable relative to the power source between a rest position and a firing position, a control system operationally associated with the power source, a trigger connected to the control system providing operator interface with the control system. The control system is configured so that an operator may select between a sequential firing mode in which the trigger must be released between firings, and a repetitive cycle mode in which the trigger is continually depressed between firings. The trigger is connected to the control system so that at least one of the frequency and duration of pulling of the trigger converts the operating mode from the sequential mode to the repetitive cycle mode.

Appl. No.:

11/028023

Inventors:

Larry M. Moeller - Mundelein IL, US
James E. Doherty - Mount Prospect IL, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B25C 1/04

US Classification:

227 8, 227 10, 227130, 123 46 SC

Abstract:

A combustion-powered fastener-driving tool includes a combustion-powered power source including a cylinder defining a path for a reciprocating piston and an attached driver blade, the piston reciprocating between a pre-firing position achieved prior to combustion and a bottom out position. Upon combustion in the power source, the cylinder includes at least one exhaust valve configured for releasing combustion gases from the cylinder. The at least one exhaust valve is dimensioned so that sufficient gas is released to reduce post-combustion pressure in the cylinder to approximately one atmosphere in the time available for the piston to travel past the at least one exhaust valve and return to the at least one exhaust valve.

International Classification:

F02B 71/00

US Classification:

227 8, 227 10, 227130, 123 46 SC, 123 46 R

Abstract:

A combustion-powered fastener-driving tool includes a combustion-powered power source, at least one fan for associated with the power source, at least one temperature sensing device in operational proximity to the power source and a control system operationally associated with the power source and connected to the at least one fan and at least one temperature sensing device for adjusting the length of time for energizing the at least one cooling fan as a function of power source temperature sensed by the at least one temperature sensing device.

US Classification:

227 8, 227 10, 227130, 123 46 SC

Abstract:

A combustion-powered fastener-driving tool includes a combustion-powered power source, a valve sleeve reciprocable relative to the power source between a rest position and a firing position, and a lockout device in operational proximity to the valve sleeve and configured for automatically preventing the reciprocation of the valve sleeve from the firing position until a piston in the power source returns to a pre-firing position.

US Classification:

227 10, 227 8, 227130, 123 46 SC

Abstract:

A combustion-powered fastener-driving tool includes a combustion-powered power source; at least one fan associated with the power source during operation; and a control system operationally associated with the power source and connected to the at least one fan for adjusting the length of time for energizing the at least one fan as a function of the number of combustion firings by the power source.
