Auto body buffing machine with handle angularly adjustable to different fixed positions

An adjustable handle mechanism for supporting a body that has a threaded opening, which is quickly and easily attachable to the body, quickly and easily adjustable, and easily detachable from the body, the handle mechanism comprising:

• an elongated threaded shaft carrying a first hand operable nut, and having a threaded forward end projecting beyond the first hand operable nut and adapted to be inserted into the threaded opening of the body so that the rotational position of the elongated shaft relative to the body may be adjusted, and the first hand operable nut may then be tightened against the body to secure the elongated shaft in its rotationally adjusted position;
• an elongated rigid hand grip;
• first and second plates disposed in parallel relation and having mutually facing roughened surfaces lying in a plane that is parallel to both the longitudinal axis of the hand grip and the longitudinal axis of the elongated shaft;
• the elongated rigid hand grip having a forward end fixedly connected to the first plate, and the elongated shaft having a rearward end fixedly connected to the second plate;
• a central shaft supporting the plates in pivotal relation to each other to form a pivot joint so as to adjust the angular relation between the longitudinal axis of the hand grip and the longitudinal axis of the elongated shaft;
• locking means for securing the pivot joint in a desired position of adjustment, the roughened surfaces of the plates then providing a secure support for imparting multi-directional forces from the hand grip to the body;
• and
• the locking means including spring means normally urging the plates apart so that their relative positions may be adjusted, and a second hand operable nut on the central shaft for tightening the roughened surfaces of the plates together against the force of the spring means.

An auto body buffing machine comprising a housing, a main handle fixedly secured to the housing, a threaded opening in the housing for attachment of an auxiliary handle, and an auxiliary handle which is quickly and easily attachable to the housing, quickly and easily adjustable to various fixed positions, and easily detachable from the housing, the auxiliary handle mechanism comprising:

• an elongated threaded shaft carrying a first hand operable nut, and having a threaded forward end projecting beyond the first hand operable nut and adapted to be inserted into the threaded opening of the housing so that the rotational position of the elongated shaft relative to the housing may be adjusted, and the first hand operable nut may then be tightened against the housing to fixedly secure the elongated shaft in its rotationally adjusted position;
• an elongated rigid hand grip;
• first and second plates disposed in parallel relation and having mutually facing roughened surfaces lying in a plane that substantially coincides with both the longitudinal axis of the hand grip and the longitudinal axis of the elongated shaft;
• the elongated rigid hand grip having a forward end fixedly connected to the first plate, and the elongated shaft having a rearward end fixedly connected to the second plate;
• a central shaft supporting the plates in pivotal relation to each other to form a pivot joint for adjusting the angular relation between the longitudinal axis of the hand grip and the longitudinal axis of the elongated shaft, the arrangement of parts being such that the longitudinal axis of the hand grip may be bent more than ninety degrees relative to the longitudinal axis of the elongated shaft;
• locking means for securing the pivot joint in a desired position of adjustment, the roughened surfaces of the plates then providing a secure support for imparting multi-directional forces from the hand grip to the body;
• and
• the locking means including spring means between the plates normally urging the plates apart so that their relative rotational positions may be easily adjusted, and a second hand operable nut on the central shaft for tightening the roughened surfaces of the plates together against the force of the spring means.
