Abstract:
A portable fastener removal apparatus for removing an elongate fastener having an axis of radial symmetry from a structure in which the fastener is embedded, the fastener removal apparatus comprising:a housing having an elongate channel which defines a housing axis, the housing further having a self-supporting base surface defining a plane generally perpendicular to the housing axis for contacting the structure and supporting the fastener removal apparatus against thereto, the self-supporting base surface being generally C-shaped, the housing being sized and configured to be positionable upon the structure such that the housing axis is coaxially aligned with the axis of radial symmetry;a force transfer member movably attached to the housing and having an engagement portion which is concentrically positioned within the channel and formed to releasably engage the fastener; anda jack attached to the housing and having a force transmission member which is cooperatively engaged to the force transfer member and reciprocally movable along a lifting axis which extends in generally parallel relation to the housing axis;wherein the actuation of the jack subsequent to the engagement of the engagement portion to the fastener and positioning of the housing upon the structure results in the movement of the force transmission member along the lifting axis in a direction away from the structure thereby imparting a lifting force to the force transfer member which moves the engagement portion along the housing axis in a direction away from the structure thus removing the fastener from therewithin.
