  • Patent number: 7222557
    Abstract: A ratcheting tool driver has a handle and a ratcheting body that includes a plurality of recesses for receiving a plurality of pawls having teeth formed thereon. A cover is axially secured to the ratcheting body and rotates relative to the body over a limited distance. The cover is formed so that it interacts with the plurality of pawls, which are operatively received in the body recesses so that they engage and disengage teeth formed on a socket ring. The socket ring contains a plurality of teeth on its outer circumference, is received in an axial bore formed in the ratcheting body, and operatively engages the pawl teeth.

  • Patent number: 7185566
    Abstract: A ratcheting tool includes a body and a gear disposed in the body. The gear defines a plurality of teeth on a circumference of the gear so that the gear teeth define a first arc having a first radius. A pawl is disposed in the body so that the pawl is movable laterally with respect to the gear between a first position, in which the pawl is disposed between the body and the gear so that the body transmits torque through the pawl in a first rotational direction, and a second position, in which the pawl is disposed between the body and the gear so that the body transmits torque through the pawl in an opposite rotational direction. The pawl defines a plurality of teeth facing the gear, and the pawl teeth define a second arc having a second radius larger than the first radius.

  • Patent number: 7153214
    Abstract: A universal joint to transmit force from a tool to a workpiece. A driver attachable to the tool has a spherical cavity. A plurality of inwardly facing protrusions is formed in the cavity. Each protrusion has a pair of conical sidewalls separated by an angled ramp. A driven socket has a sphere formed on one end. The sphere has a plurality of channels. The sphere is received in the spherical cavity in the driver and the protrusions in the cavity are received in the channels. The drive webs forming the channel engage the protrusions when the driver is angularly offset from the driven socket.

  • Patent number: 7073412
    Abstract: A method is provided for forming a pawl pocket in a ratcheting tool wherein a keyway cutter at the end of an elongated pin removes material from the neck portion of a wrench. When removing material from the tool's neck portion, a predetermined path of the keyway cutter defines two flat surfaces on respective opposing sides of the pawl pocket, with each flat surface forming an angle preferably in the range of about 27 to 35 degrees between a centerline of the pawl pocket and the flat surfaces themselves.

  • Patent number: 7051623
    Abstract: The present invention provides a wrench having a handle integral with a ratchet head. The ratchet head defines a chamber having a generally circular sidewall. An annular rotor having radial teeth about an outer surface thereof is located in the chamber. The rotor teeth engage a set of teeth extending radially inward from the sidewall of the chamber. A biasing element, such as a leaf spring, is provided to urge the rotor teeth into engagement with the sidewall teeth. Preferably, the sidewall teeth will be configured having progressively increasing heights in the direction in which the rotor turns during ratcheting.
