Abstract
Abstract This is a car repair jack for manually or electrically applying pushing or pulling pressure to automobile body or bumper parts which have become bent, as in an accident, to straighten them out as much as possible. It utilizes a jack consisting of a stanchion which is inserted in a socket fixed in the pavement. Pivotally journaled on the top of the stanchion is a screw rotatable in either direction by a manually operable crank handle or low power reversible electric motor. The screw is threaded through a nut pivotally secured at the top of an angular arm whose bottom end is pivotally clamped on the stanchion substantially below the top. A bracket, in the same plane with the screw, is adjustably pivoted by a removable pivot pin to the angular arm, and extends beyond the stanchion and has a screw thread therein in which a hook or a push-bar may be threaded. A chain is placed on the hook, so that a suitable clamp or hook may be placed about a bumper for pulling out a dent, and a push-bar may be threaded into the bracket instead of the hook for applying push pressure to any part of the car body or bumper.
