20090152316 | SELECTABLE FIRING MODE WITH ELECTROMECHANICAL LOCKOUT FOR COMBUSTION-POWERED FASTENER -DRIVING TOOL - A combustion-powered fastener-driving tool includes a power source including a cylinder and a valve sleeve reciprocating relative to the cylinder between a closed position defining and closing a combustion chamber, and an open position allowing venting of the combustion chamber. A lockout device is associated with the power source and is configured for releasably restraining the valve sleeve in the closed position. A control system is connected to the power source, is operable in both a sequential firing mode and a repetitive firing mode, and is configured for activating the lockout device in a first format when in the sequential firing mode, and in a second format when in the repetitive firing mode. | 06-18-2009 |
20100163594 | COMBUSTION CHAMBER DISTANCE CONTROL FOR COMBUSTION-POWERED FASTENER-DRIVING TOOL - A combustion-powered fastener-driving tool includes a combustion-powered power source including a cylinder head and a combustion chamber defined by the cylinder head, a valve sleeve and an upper surface of a reciprocating piston, the valve sleeve reciprocable relative to the cylinder head between a rest position and a pre-firing position. The valve sleeve has a range of positions between a first sealing position in which the combustion chamber is closed, and said pre-firing position in which the valve sleeve is prevented from further movement. A lockout device is associated with the power source and has an actuated position configured for preventing the reciprocation of the valve sleeve beyond the first sealed position to open the combustion chamber, but permitting movement of the valve sleeve from the first sealed position to the pre-firing position until the piston returns to a piston pre-firing position post combustion. | 07-01-2010 |

20100026427 | SWITCHING DEVICE - The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments. | 02-04-2010 |
