Filed:

Apr 16, 2008

Appl. No.:

12/104323

Inventors:

Christopher Andrew Mattson - Provo UT, US
Brian G. Winder - Ridgecrest CA, US
Allen Boyd Mackay - Flagstaff AZ, US
Joseph O. Jacobsen - Pleasant Grove UT, US
Peter A. Halverson - Alpine UT, US
Spencer Frazer - Lynnwood WA, US

Assignee:

Brigham Young University - Provo UT

International Classification:

B25B 7/12

US Classification:

81368, 81367, 81384

Abstract:

A hand tool having first and second plier units attached to one another where a jaw region is operatively configured to have a work piece to be placed therein and a handle region is configured to be used by the user of the tool to grasp the work piece. A tension member is provided to be positioned past a dead point axis so as to apply a clamping force upon the jaw member and the hand tool maintains a grip upon the work piece without continuous interaction with the user of the tool.

US Classification:

173 1, 173 90, 81 28, 81436

Abstract:

A hand tool impacting device may include, a drive shaft with an aperture, an impaler disk, and a floating pin positioned within the aperture of the drive shaft. A set of circular ramps on the outer edge of the impaler disk may interact with a stationary pin insert to translate the drive shaft and create an impacting motion. A pair of springs placed against either side of the floating pin may allow a specialized tool bit to engage or disengage the impaler disk, thereby allowing selective use of translational impacting motion, or rotational torque. An impact bit for engaging the impaler disk may include, a tool head configured to engage a work piece and a tool shaft configured to be inserted into a hollow drive shaft to engage a floating pin. According to one embodiment, the impact bit includes a number of sleeves to guide the tool head during operation.

US Classification:

173 94, 173216

Abstract:

A drive train for supplying power to a power tool may include, a motor, a motor shaft, a rotational coupling mechanism connected to the motor shaft, and a drive shaft connected to the rotational coupling mechanism that forms the shape of a “U.” A pair of enmeshed bevel gears transfers the motion from the motor shaft to an orthogonal tool bit. The drive train may also include a hammering device that transfers a rotational impacting motion to the tool bit. A hand power tool for driving a screw may include a tool shell with an integrally formed vertical handle, a rotational recess formed into the tool shell opposite the handle, and a tool chuck within the rotational recess that drives a screw. The tool may incorporate the drive train as described above. The tool may include a mechanism for locking the tool chuck in a particular position.
