Patent ID: 7281552

Claim:
A carving assembly for duplicating a form having a certain shape, the carving assembly comprising: a frame assembly having a pair of substantially parallel and horizontal first rails, a second rail which is perpendicular to the pair of first rails, a pair of vertical support members each including at least one first linear bearing, wherein a unique one of the first rails is slidably disposed within each of the linear bearings, and wherein the second rail is disposed between the pair of vertical support members; a carriage assembly having a tubular member containing at least one second linear bearing and a first substantially flat mounting surface which is pivotally coupled to the tubular member, wherein the second rail is slidably disposed within the at least one second linear bearing; a handle member which is coupled to said carriage assembly, said handle member having a handle portion and a stylus portion, wherein the handle member is coupled to and orthogonally projects from the mounting surface and wherein the handle portion and the stylus portion extend from the handle member in substantially opposite vertical directions; and a tool holder member which is coupled to said carriage assembly, wherein the tool holder member includes a collar portion which is adapted to selectively receive a conventional cutting tool, wherein the tool holder member is coupled to and orthogonally projects from the mounting surface and wherein said tool holder member moves in response to said movement of said holder member; and a chain assembly operatively coupled to the carriage assembly, wherein the chain assembly includes first and second screw members which are each movably coupled to the frame assembly and a chain which is coupled to each of said screw members, said chain assembly being effective to restrain movement of said carriage assembly in a certain direction thereby allowing said tool holder member to accurately carve a workpiece in response to said movement of said holder member.
