Abstract:
1. A dual-drive ratcheting device, that, within the same embodiment, can be set to clockwise rotational output and converts oscillatory motion applied to an input, into solely clockwise rotational motion at an output; and can be set to counter-clockwise rotational output and converts oscillatory motion applied to said input, into solely counter-clockwise rotation motion at said output and comprising; a driveshaft; at least two driving elements spaced apart and coaxially mounted on said driveshaft with each driving element coupled to a means for engaging and disengaging said driveshaft, so that the driveshaft is always entrained in only one direction of axial rotation, when at least: one of the said driving elements is rotated in that direction, while the driveshaft is overrun by driving elements, that are rotated in the opposite direction; a reversing element, coupling the driving elements together and causing said driving elements to always rotate in opposite directions, so that at least one of said driving elements entrains the driveshaft and the remaining, overrides the driveshaft, thus causing the driveshaft to always rotate axially, in only one direction, regardless of the direction of rotation of the driving elements; an adjustable-angle input handle, having a pistol type grip and a non-coaxial disposition with the driveshaft for optimum user comfort and efficiency and rotates axially clockwise and counterclockwise and swings radially for increased torque, wherein said adjustable-angle input-handle is coupled to said reversing element, which is accessible through an opening in the wall of a reversing mechanism housing, to simultaneously prevent the axial rotation of said reversing mechanism housing, while enabling the turning of the input handle axially repeatedly and alternatingly clockwise and counterclockwise, thereby activating the dual-drive action single-handedly, with said handle axially turning said reversing element alternatingly in clockwise and counterclockwise directions, while reversing element meshes with and causes the first and second driving miter gears to coaxially rotate oppositely, to cause the engaging means to alternatingly engage and disengage, to entrain the driveshaft, into a single selected direction-of-rotation at the output and enable a user's opposite hand to hold a workpiece; and a pivoting means, for the handle to be positioned radially as required.
