  • Patent number: 8707831
    Abstract: A dual-drive self-ratcheting device, that efficiently converts alternating clockwise and counterclockwise rotation applied to its input, into unidirectional rotation at its output, by employing a plurality of means, such as, but, not limited to, ratchet and pawls or roller-type clutch mechanisms, oriented the same and arranged in tandem, on a common drive shaft and caused to alternately drive the shaft continuously in either all clockwise or counterclockwise direction, as oscillatory motion is applied to its input; while the first ratchet and pawl or roller clutch mechanism is caused to impart motion onto a drive-shaft, the second ratchet and pawl or roller clutch mechanism is simultaneously caused to override the driveshaft; while the second ratchet and pawl or roller clutch mechanism is caused to impart motion onto a drive-shaft, the first ratchet and pawl or roller clutch mechanism is simultaneously caused to override the driveshaft; hence regardless of the direction of rotation applied to the input, the

  • Publication number: 20120096991
    Abstract: A dual-drive self-ratcheting device, that eliminates the unproductive ratcheting-up motion between each productive drive, by employing a plurality of ratcheting or clutching mechanisms arranged in tandem, on a common drive shaft, that are caused to alternately drive the shaft continuously in one direction, as oscillatory motion is applied to its input. While the first ratcheting/clutching mechanism is caused to impart motion onto a drive-shaft, the second ratcheting/clutching mechanism is simultaneously caused to override the driveshaft. While the second ratcheting/clutching mechanism is caused to impart motion onto a drive-shaft, the first ratcheting/clutching mechanism is simultaneously caused to override the driveshaft.
