In one embodiment, the tool has a fastener engagement portion toward a first end, a fastener removal portion toward a second end, and an impact surface positioned between the fastener engagement and fastener removal portions. The fastener engagement portion is configured to releasably engage a fastener, and is offset from the impact surface to facilitate positioning a fastener in a confirmed space. The impact surface is configured to remain accessible once the fastener has been properly positioned for installation. A user can strike the impact surface to drive the fastener into a workpiece. The fastener removal portion is configured to engage an installed fastener to extract the installed fastener from the workpiece.Type: GrantFiled: June 13, 2000Date of Patent: March 5, 2002Assignee: Shear Technologies, LLCInventor: Timothy J.

Patent number: 6351881Abstract: A hinge pin removal and starter device is disclosed, comprising a bar portion having a first and second end portion. The first end portion of said bar tapers to a flattened tip having a concave edge. A cylindrical projection adjacent the opposite butt end protrudes from said second end portion a generally perpendicular direction thereto. The tip of said first end portion is adapted for forcible insertion between the head of a hinge pin and a hinge, to wedge the hinge pin and hinge apart and detach said pin from said hinge plate. The cylindrical projection adjacent said second end portion is adapted to be placed in abutting relation to said pin opposite the head of said pin and a force applied against the pin through the cylindrical projection, to at least partially displace said pin from the hinge plate into which the pin is inserted.Type: GrantFiled: November 20, 2000Date of Patent: March 5, 2002Inventors: Ronald S. Peckich, Vincent G. Motta

Patent number: 6322302Abstract: An improved snap buckle tool for opening and closing a snap buckle of the type used in combination with a flexible strap member to adjust the tension thereof is disclosed. The snap buckle tool comprises an elongated handle member integrally formed with a generally C-shaped head member. An elongated slot divides the terminal end of the head member into a pair of parallel tines which engage a snap buckle to alternately manipulate the snap buckle from a closed condition to an open condition to adjust the tension of the strap. The slot is disposed at a predetermined angle relative to a longitudinal axis of the handle member to facilitate use of the tool against a surface of a shipping container to gain a mechanical advantage in opening and closing the snap buckle.Type: GrantFiled: April 17, 1998Date of Patent: November 27, 2001Inventor: Thomas E. Horton
