  • Dual directional power feed
    Patent number: 6655228
    Abstract: The present invention discloses a dual directional power feed for use with handheld drills or stationary frame mounted power sources. The device comprises a housing, two pairs of wheel bearings rotatably mounted to the housing, a cap rotatably mounted to the housing, and a biasing bearing rotatably mounted to the cap. The cap is rotatable to a first position such that rotation of the threaded cable in a first direction causes the threaded cable to translate along its longitudinal axis in a first direction. The cap is further rotatable to a second position such that rotation of the threaded cable in the first direction causes the threaded cable to translate along its longitudinal axis in a second direction, opposite the first direction. Further, the present invention discloses a bearing and support assembly for coupling a power feed device to a power unit comprising a support plate and a bearing.
