Abstract: Apparatus and methods for making spectacle lens patterns are disclosed. The apparatus uses a router (or similar) bit, a spring-loaded, adjustable follower, and an existing lens (or pre-cut model) to produce patterned blanks either identically or proportionally sized to corresponding template or model lenses. The router bit rotates rapidly about its longitudinal axis as it penetrates the slowly rotating blank, producing a smooth pattern after as few as one rotation of the blank. The cover of the invention maintains the follower and cutting bit in suitable (albeit adjustable) alignment while permitting easy access to the interior of the device for inserting and removing both the lens and blank. A chute, pouch, or chip containment cavity may also be included to receive the by-products of the cutting operation for easy disposal.

Abstract: The coordinate slides of a computer controlled punching and nibbling machine are coupled by resilient elements with respective nuts engaging screws driven by motors controlled by computer programming. The resilient coupling between the slides and the respective nuts permits the motors to run and thereby drive the nuts during periods when the slides are held stationary by engagement of the punching and nibbling tool with a workpiece mounted on the upper slide. As soon as the tool is disengaged from the workpiece, the workpiece is quickly moved to the next position by energy stored in the resilient elements. A sensor between each of the slides and the respective nut senses the displacement of the nut relative to the slide and transmits this information to the computer.

Abstract: The invention relates to a hole forming machine which has two or more punching heads for punching holes in a sheet of metal. The sheet of metal is moved relative to the punching heads in a guide frame to which is attached a stylus. The stylus is swept over a template having a pattern of pilot holes formed therein. By locating the stylus sequentially in the pilot holes and operating the punching heads, the pattern of holes on the template can be mapped on to the sheet of metal. The provision of two or more punching heads substantially reduces positional errors in the punched pattern.

Abstract: A stylus is mounted on a carriage which also supports a work plate adapted to be positioned beneath a punch. When the punch first strikes the work plate, the stylus is automatically retracted out of a hole in a template so as to free the carriage to shift forwardly in unison with the work plate as the punch continues through the plate.

Abstract: An apparatus for shaping a wooden workpiece according to a template configuration has a carriage displaceable on a track parallel to a guide edge of a template clamped on a table to one side of the track. A workpiece is clamped to a table to the opposite side of the track. A slide is displaceable on the carriage transverse to the track and carries on one end a roller engaging the guide edge of the template and on its other end a driven tool for cutting the shape of the template into the workpiece. The slide is urged toward the workpiece so that virtually no lateral force is exerted against the workpiece, the guide edge acting as a stop positively determining the transverse position of the slide. Another template can support a second feeler roller which is connected via a chain or the like to the tool to raise and lower this tool according to the guide edge on the second template for two-sided cutting of the workpiece.
