Abstract
A double-acting wrench has a main handle and a holding handle, the end of the main handle being connected to a set of reversing gears, and through a ratchet and double pawls to the cage in which the set of reversing gears are mounted. The reversing gears, or the cage in which they are mounted, are selectively connected to a tool driver. Ratchets and double pawls are engageable so that rotation of the main handle in either clockwise or counterclockwise direction with respect to the holding handle will produce continuous clockwise or counterclockwise rotation of the tool driver.
Claims8
A wrench for rotating a tool driver in a continuous selected clockwise or counterclockwise direction by clockwise and counterclockwise rotation of a handle which comprises:
- a. a main handle and a holding handle, each having an end rotatably mounted on a common shaft;
- b. a set of reversing gears mounted in a gear cage fixedly attached to said shaft;
- c. said main handle being fixedly attached to the input gear of said set of reversing gears;
- d. a tool driver fixedly attached to the output gear of said set of reversing gears;
- e. pawl and ratchet means for selectively connecting said main handle through said gear cage with said set of reversing gears locked in said gear cage, to said tool driver when said main handle is rotated in one of clockwise and counterclockwise directions with respect to said holding handle, and through said set of reversing gears rotatably operable in said gear cage, when said main handle is rotated in the other of clockwise and counterclockwise directions with respect to said holding handle;
- and
- f. means for selectively locking said pawl and ratchet means in position for rotating said tool driver in one of continuous clockwise and counterclockwise directions during clockwise and counterclockwise rotation of said main handle with respect to said holding handle.
Apparatus for rotating a driven member in a continuous selected clockwise or counterclockwise direction by repetitive and sequential clockwise and counterclockwise rotation of a driving arm with respect to a stationary member, which comprises:
- a. said driving arm and said stationary member each being rotatably mounted on a common shaft;
- b. a set of reversing gears mounted in a gear cage fixedly attached to said shaft;
- c. said driving arm being fixedly attached to the input gear of said set of reversing gears;
- d. a driven member fixedly attached to the output gear of said set of reversing gears;
- and,
- e. pawl and ratchet means for selectively connecting said driving arm through said gear cage with said set of reversing gears locked in said gear cage, to said driven member when said driving arm is rotated in one of clockwise and counterclockwise directions with respect to said stationary member, and through said set of reversing gears rotatably operable in said gear cage, when said driving member is rotated in the other of clockwise and counterclockwise directions with respect to said stationary member.
