Patent number: 7454997Abstract: An axial pawl ratcheting mechanism is provided that may be used for a wrench and comprises a first disc including axial gear teeth on a first side providing for ratcheting in a first direction. A second disc is provided having axial gear teeth and peripheral gear teeth. The second disc is mounted to the first side of the first disc so that the first disc axial gear teeth engage the second disc axial gear teeth and provide an axial pawl ratchet assembly. A ratchet head is provided having an internally toothed opening for receiving the axial pawl ratchet assembly therein so that the peripheral gear teeth of the second disc engage the internal diameter teeth of the ratchet head in order to transfer torque between the ratchet head and the axial pawl ratchet assembly. An actuator is provided for adjusting the positioning of the axial pawl ratchet assembly between a first engagement position and a second engagement position.Type: GrantFiled: January 8, 2004Date of Patent: November 25, 2008Assignee: Snap-on IncorporatedInventors: Gordon A.

Patent number: 7445055Abstract: A tip valve assembly for a pneumatic tool with an integrated wear surface. The tool has a portion with an air channel bore housing. The tip valve assembly includes a first valve member having a bore and defining a valve seat about the bore and a second valve member capable of forming a seal with the valve seat. The second valve member can be tilted from the valve seat to permit air flow through the bore of the first valve member. The wear surface projects over only a portion of the cylindrical wall in the bore housing in conjunction with an edge of the second valve member that can be tilted farthest, so the second valve member does not contact the cylindrical wall of the bore housing. As an anti-rotation feature, the second valve member may have an outer periphery with a shaped recess between lobes.Type: GrantFiled: November 3, 2006Date of Patent: November 4, 2008Assignee: Snap-On IncorporatedInventors: Daniel S. Pusateri, James R. Brehm

Patent number: 6883617Abstract: An automatic shutoff mechanism is designed for a pneumatic tool having an air motor, a pressurized airflow path to the motor and a torquing mechanism driven by the motor. The shutoff mechanism includes a valve member moveable between open and closed positions relative to the airflow path and biased to the open position. A trip apparatus is responsive to application of a predetermined torque for moving the valve member to a trip position disposed in the airflow path sufficiently to expose the valve member to the pressurized airflow for driving the valve member from the trip position to the closed position. Mechanical and electromechanical embodiments are disclosed.Type: GrantFiled: May 8, 2003Date of Patent: April 26, 2005Assignee: Snap-on IncorporatedInventors: Gordon A. Putney, Daniel S. Pusateri, Dean J. Iwinski, Daniel D. Lionberg

Patent number: 6796389Abstract: A power hand tool body has a barrel with a depending skirt portion from which depends an elongated handle. Elongated grooves are formed in opposite sides of the skirt portion and extend between forward and rearward ends thereof, the grooves being part-cylindrical in transverse cross-section and having rectangular cross-section neck portions opening at the sides of the skirt. A hollow tubular grip formed of flexible and resiliently stretchable material has an end portion with part-cylindrical attachment members extending laterally and inwardly from opposite sides thereof so that, when the grip is slipped over the handle, the end portion may be stretched to insert the attachment members respectively into ends of the grooves for retaining the grip in place.Type: GrantFiled: June 24, 2002Date of Patent: September 28, 2004Assignee: Snap-on IncorporatedInventors: Daniel S. Pusateri, John A. Pierman

Patent number: 6634438Abstract: The pneumatic tool includes a housing which encloses a majority of the pneumatic tool. The housing is comprised of a body and a handle depending from the body and defining an input air passageway. A reversing valve lies partially disposed within the housing, intermediate the body and the handle. The body defines a preferably cylindrical motor cavity communicationg at its bottom with the input air passageway and at its top with an exhaust passageway located above the motor cavity. A pneumatic motor is disposed within the motor cavity. The pneumatic motor can include front and rear plates, a rotor rotatively suspended between the plates, and a cylinder disposed between the plates and in sealed engagement thereto. The cylinder has an upper portion with an exhaust port communicating with the exhaust vent and a lower portion with an air inlet communicating with the input air passageway to provide a substantially diametral airflow path through the motor.Type: GrantFiled: June 1, 2001Date of Patent: October 21, 2003Assignee: Snap-on Technologies, Inc.Inventors: Daniel S.
