US Patent:

Filed:

Apr 14, 2005

Appl. No.:

11/106299

Inventors:

Mathias Wottreng, Jr. - Cincinnati OH, US
Gary Michael Bohart - Cincinnati OH, US

Assignee:

DuraSpin Products LLC - Cincinnati OH

International Classification:

B23Q 5/08
B23Q 5/28

US Classification:

173176, 173 2

Abstract:

An improved hand-held fastener driving tool is provided with an adjustable torque limiting control. The tool is portable, and is electrically powered using either a battery pack or a power cord as a power source. The tool drives collated fasteners (e. g. , screws) into solid objects. The motor current is measured to determine the amount of torque being applied to a screw by the motor and mechanical drive components. As the screw bottoms out, the motor torque increases to a point where it exceeds the user-adjusted torque limiting control. The motor is automatically turned off at that point, thereby preventing the screw from being stripped.

Abstract:

An improved fabrication apparatus is provided for the placing screws accurately and reliably into body panels of cargo trailers. The apparatus uses a template that is positioned over the aluminum body panels of a cargo trailer to guide the placement of automatic screwdriver tools, so that the body panels are quickly and accurately mounted to vertical ribs that are part of the framework of the trailer. The invention includes a fabrication fixture that holds the template at predetermined positions to align the template with the ribs of the trailer's framework.

Inventors:

William Hoffman - Cincinnati OH, US

Michael Desmond - Newport KY, US
Gary Bohart - Cincinnati OH, US

International Classification:

B25C005/02

US Classification:

173029000, 227136000

Abstract:

An improved hand-held screw driving tool is provided with a quick release nose sub-assembly, which can readily be attached to and detached from a main body of the tool. This capability allows the tool to be used in several different ways, by putting different nose sub-assemblies onto the main body of the tool. For example, one nose sub-assembly could drive a strip of collated screws, whereas a different nose sub-assembly could use single feed screws that are individually placed at a drive position of the nose sub-assembly. Another possible nose sub-assembly is a cutter or shears attachment that can be driven by the rotary motion of the tool's motor. Various sizes and types of fasteners can be driven by this tool.
