  • Patent number: 11052515
    Abstract: The 90 Degrees utilizes dual ratio constant mesh gears which provides suitable use for ratchets in hard to access spaces, and particularly well suited for automotive use. The mesh gears are configured to be used either with manual or pneumatic tools. A female socket element recedes into the housing having gears therein and a male socket element meshes with the female socket element and is shaped to accommodate a female socket element at 90 degrees or the adapter element of a drive ratchet. You can use an elongated drive shaft to accommodate distance. Positioned within the housing of the adapter body are gears secured to mesh within the housing of the adapter. Rotation of the female socket element by a drive ratchet in one direction will rotate the male socket element in the opposite direction without any change in direction is governed by the ratchet use.

    Abstract: The swiveling ratchet involves a rotating socket that is in mechanical communication with a drive ratchet, which is able to rotate there between. The drive ratchet is driven via a handle that would rotate about a longitudinal axis. The rotating socket is rotated via a worm gear positioned inside of a socket housing. The worm gear features drive gears at distal ends. The drive gears are both in mechanical communication with a bevel gear that extends to the drive ratchet. Both the drive ratchet and the bevel gear freely rotate about a worm axis, which enables the handle and drive ratchet to rotate collectively with respect to the socket housing, and maintaining mechanical communication between the drive ratchet and rotating socket.

  • Patent number: 7454997
    Abstract: An axial pawl ratcheting mechanism is provided that may be used for a wrench and comprises a first disc including axial gear teeth on a first side providing for ratcheting in a first direction. A second disc is provided having axial gear teeth and peripheral gear teeth. The second disc is mounted to the first side of the first disc so that the first disc axial gear teeth engage the second disc axial gear teeth and provide an axial pawl ratchet assembly. A ratchet head is provided having an internally toothed opening for receiving the axial pawl ratchet assembly therein so that the peripheral gear teeth of the second disc engage the internal diameter teeth of the ratchet head in order to transfer torque between the ratchet head and the axial pawl ratchet assembly. An actuator is provided for adjusting the positioning of the axial pawl ratchet assembly between a first engagement position and a second engagement position.

  • Patent number: 7395738
    Abstract: This invention relates to bi-directional ratcheting socket wrenches having two modes of operation that can be used independently or simultaneously and having only one ratchet mechanism. This invention can rotate a work piece by being rotated around the socket axis as is common to socket wrenches, the handle can be rotated around its axis or the two motions can be combined as one fluid motion. This can be accomplished in either direction of rotation while permitting the ability to reposition the wrench and/or the handle. Again, this is achieved using a single ratchet mechanism. This invention also provides a means to lock the handle in position relative to the wrench itself, a means to sufficiently retain the handle without impeding handle rotation, a means to mount the handle on a bearing and a means to provide alternative embodiments of the wrench to further increase its usefulness in confined areas.

  • Patent number: 7347124
    Abstract: In accordance with the present invention there is provided a drive tool assembly that includes a shaft having a drive end portion and a driven end portion with a longitudinal axis extending therebetween. The shaft driven end portion is flexible relative to the shaft drive end portion to permit displacement of the shaft driven end portion in an arcuate path relative to the shaft drive end portion. A torque transmitting mechanism is drivingly connected to the shaft driven end portion. Means is provided for supporting the torque transmitting mechanism on the shaft driven end portion for transmission of torque from the shaft drive end portion through the shaft driven end portion to the torque transmitting mechanism as the shaft driven end portion is displaced from the shaft drive end portion in an arcuate path along the longitudinal axis.

  • Patent number: 7340981
    Abstract: A tool is provided in the form of an angled and/or offset ratchet wrench extension. The angles may be selected, but in a preferred embodiment, a ratchet extension provides a right angle drive. The tool comprises a socket driver that is adapted to be connected to a socket and a rotatable drive shaft rotatably mounted within a housing. A first direction changing transmission is provided near the end for converting the rotatable drive shaft motion to rotary motion to drive the socket driver at the specified angle. A ratchet wrench is connected to the distal portion of the rotary drive shaft. In a second embodiment, a second direction changing transmission is located near the distal portion of the rotatable drive shaft for converting the rotary motion of a ratchet wrench to the rotary motion of the rotatable drive shaft. The length of the extension may be adjustable.
