摘要： A manually-powered drive device includes a drive train substantially disposed in a hollow housing. A laterally sliding transmission shaft extending laterally in an intermediate frame portion of the housing includes first and second circumferential recesses. A transmission selector spring flexes and removably slidably couples within the first circumferential recess or the second circumferential recess as the transmission shaft laterally slides between alternate positions, thereby selecting the desired rotational direction for manipulating fasteners. Another manually-powered drive device includes a first drive assembly extending coaxially in the barrel portion of the housing and a second drive assembly extending in the intermediate frame portion of the housing between any acute angle and any obtuse angle to the first drive assembly. A manually-powered drive device assembly includes a manually-powered drive device removably coupled with a removable attachment tool configured to transmit motion and driving force to a fastener for manipulation.

摘要： A hand operated device and method for assisting a user in driving the device's shaft to impart driving force to a fastener more than conventionally accomplished in a fixed period of time. The device has a first member and a second member gripped with the user's first hand, while a handle of the shaft is held with the user's second hand. The user then turns the second member in a first direction, while still gripping the first member, so as to rotate the shaft. Next, the user releases grip on the second member while rotating the first member in a second direction, freely, without the first member ever rotationally engaging the shaft. Simultaneously, the user grips and rotates the handle in the first direction so as to continue to rotate the shaft. The user then repeats the aforementioned steps to drive the shaft as desired so that the first member never rotationally engages the shaft.

摘要： A variable speed ratchet wrench comprising a main handle portion with an opening for receiving a planetary gear mechanism, a planetary gear mechanism with a locking device attached to an output shaft for driving wrench fittings, and a planetary gear housing cover. The planetary gear housing cover comprises an attached secondary handle that allows the planetary gears to revolve relative to the sun gear in a non-locked position and prevents the planetary gears from revolving about the sun gear when locked in a locked position, thereby providing a geared speed increase in the driven speed of the output shaft. The planetary gear mechanism includes a sun gear, a first and second planetary gear, and an inner ring gear for driving the output shaft.
