Abstract

A drive mechanism provided with a forward and reverse input and a forward and reverse drive whereby a single output-member is caused to produce forward drive from forward-rotation, reverse-rotation and oscillatory-rotation applied to a single input-member whereby the reverse-rotation applied to the input-member is mechanically converted to usable forward drive through an arrangement of gears and one-way clutches and thereby doubling the efficiency of the input and drive while the single output-member can also be caused to produce reverse drive from forward-rotation, reverse-rotation and oscillatory-rotation applied to the input-member whereby the forward-rotation applied to the input is mechanically converted to usable reverse drive through an arrangement of gears and one-way clutches with forward drive being achieved by an identical pair of geared and spring-loaded pivotable selector mechanisms at the input and output end of the device pivotting into simultaneous engagement with the geared input member and a geared forward-rotation-mechanism designated for producing only forward drive and with reverse drive being achieved by the same pair of geared and spring-loaded selector mechanisms pivoting into simultaneous engagement with the geared input-member and geared reverse-rotation-mechanism designated for producing only reverse drive.

A device for mechanically converting oscillatory-rotation of input to forward-rotational-drive and converting oscillatory-rotation of input to reverse-rotational-drive comprising:

an output-member capable of forward-drive by applying forward, reverse and oscillatory-rotation to an input-member,
an output-member capable of reverse-drive by applying forward, reverse and oscillatory rotation to an input-member,
a forward-rotation-mechanism for receiving and transferring forward-rotation from input-member to output-member when forward-drive is desired,
a forward-rotation-mechanism for receiving reverse-rotation from input-member, converting reverse-rotation into useable forward-rotation then transferring the converted forward-rotation to output member when forward-drive is desired,
a reverse-rotation-mechanism for receiving and transferring reverse-rotation from input-member to output-member when reverse-drive is desired,
a reverse-rotation-mechanism for receiving forward-rotation from input-member, converting forward-rotation into useable reverse-rotation then transferring the converted reverse-rotation to output member when reverse-drive is desired,
a geared and spring-loaded input selector mechanism pivotably mounted onto the internal end of input-member and caused to pivot and become retained into engagement with forward-rotation-mechanism thereby providing the mechanical path for transferring rotational motion from input-member to forward-rotation-mechanism then be caused to pivot out of engagement from forward-rotation-mechanism and become retained into engagement with reverse-rotation-mechanism thereby providing the mechanical path for transferring rotational motion from input-member to reverse-rotation-mechanism.
a geared and spring-loaded output-selector-mechanism pivotably mounted onto the internal end of output-member and caused to pivot and become retained into engagement with forward-rotation-mechanism thereby providing the path for transferring rotational motion from forward-rotation-mechanism to output-member and then be caused to pivot out of engagement from forward-rotation-mechanism and become retained into engagement with reverse-rotation-mechanism thereby providing the mechanical path for transferring rotational motion from reverse-rotation-mechanism to output-member,
a three-piece housing for enclosing and supporting aforementioned components.
