摘要:
A coping apparatus facilitating a coped or straight cut through molding by using a stylus to trace the molding being cut to guide the cutter with adjustability for wall-to-ceiling, wall-to-floor, wall-to-wall, and/or backcut angles is presented. The apparatus includes a rotatable holder assembly, a rotatable cutter assembly, a rotatable platform, and a base element. The rotatable holder assembly includes a two-axis positioning system and allows for adjustment to left or right, straight or coped cuts and wall-to-wall angles. The rotatable cutter assembly is attached to the two-axis positioning system and allows adjustment to the left or right, straight, or cope cuts and backcut angle and further includes a motor driven spiral cutter, a cutter holder, and at least one stylus. The rotatable platform allows adjustment to the wall-to-floor or wall-to-wall angle and is movable so as to rotate or swivel about a vertical axis substantially perpendicular to the rotational axis of the holder and cutter assemblies. The base element is attached to and supports the rotatable holder assembly, rotatable cutter assembly, and rotatable platform in a substantially perpendicular arrangement.

The invention provides a woodworking duplicator which is adapted to be attached to a standard radial arm saw. The device allows a rotating cutting tool and a stylus to be movably supported allowing the user to trace a pattern with the stylus while cutting the pattern into a work piece with the cutter. The invention provides a duplicator that may be mounted to a radial arm saw wherein the duplicator includes elements that may be moved in five different directions. The invention also provides a duplicator having a stylus and a cutter that may be easily locked into different parallel positions so that the user of the duplicator may more easily trace the item being duplicated. The invention also provides a duplicator that supports the weight of the stylus and cutter tool.

The present invention is directed to enhancing the accuracy with which tooth restorations are performed, including the manner by which a tooth is prepared and fit with a dental prosthetic. Further, the present invention is directed to reducing the skill dependent tasks associated with tooth restoration, while at the same time, improving the precision with which these procedures are performed. By improving the accuracy of restoration procedures, any need to repeat these procedures for a given patient can be eliminated and patient comfort can be improved.

Apparatus for scribe engraving a workpiece with a miniature representation of a two-dimensional pattern in response to movement of a stylus following the pattern includes a spherically rotatable member having a frusto-spherical surface rotatably retained within a frusto-spherical bearing race remote from the pattern and having a passageway therethrough axially skew to the pattern, where the scribe extends fixedly from the spherically rotatable member for movement unitarily with the rotatable member, including means for connecting the rotatable member with the stylus so that the rotatable member rotates in response to stylus movement following the pattern where the connecting means is selectably disengageable from the rotatable member.
