An apparatus for positioning a workpiece guiding fence relative to a rotary cutter projecting through the top surface of a work table, comprising a plurality of major components, primarily formed by aluminum extrusions, including a base element securable to the work table surface and having upstanding guiding ribs, an elongated hollow carriage slidably mounted on said ribs and defining a partially cylindrical elongated recess mounting an elongated lead screw. A fence is secured to one end of the carriage. A threaded segment is mounted on a force transmitting element which is moved laterally to engage the threaded segment with the lead screw by a pivoted camming lever having three positions. In the first position, the threaded segment is disengaged from the lead screw, permitting unrestricted longitudinal movement of the carriage relative to the base. In the second position, the threaded segment is engaged with the lead screw, permitting only incremental longitudinal movement of the carriage by rotation of the lead screw. In the third position, the threaded segment remains engaged with the lead screw and the force transmitting element exerts a clamping force on one of the supporting ribs on the base plate to lock the carriage against all movement during the cutting operation.

Fence positioning apparatus

A workpiece guiding fence for a woodworking machine having a rotating vertical axis cutting tool comprises a fence support of hollow rectangular configuration defining a chamber which is connectable to a vacuum source for removal of dust and chips. A three part fence structure comprises a forward fence portion, a rearward fence portion, and an insert portion are adjustably positionable on the fence support. The insert portion is fabricated from a cuttable material and is moved into full engagement with the rotating cutting tool to provide a recess conforming to the configuration of the cutting tool. When a workpiece is guided along the aforedescribed three part fence, dust and chips produced by the cutting operation are withdrawn into the fence support by the vacuum source. Subsequent operations utilizing the same cutting tool permit the insert, which has been cut to conform to the configuration of such cutting tool, to be mounted on the fence and to effect the rapid, yet highly accurate, alignment of the three part fence with the specific cutting tool.

Fence for woodworking machine

Method and apparatus for the fixturing and positioning of objects such as workpieces or lenses in a repeatably presettable position relative to, for example, a cutting tool or other optical components includes a fixed base (40), a carriage (20) and a lead screw (30) rotatable with respect to the fixed base. The carriage (20) translates relative to the base and moves objects attached to it. The exact position of the carriage is indexed by first pressing a button (80A) to release an inside threaded concave cylindrical clamping piece (64) between the carriage and the lead screw and manually moving the carriage (20) to a desired location dictated by a scale (42A, 42B) on the fixed base (40) to relocate to a course number of thread pitch spacings. Once relocated the button (80A) is released, the carriage (20) is again clamped to the lead screw and the carriage finally incremented into a more accurate fine position with respect to the scale (42A, 42B) by an indexed rotation of a lead screw thumb screw (32) with respect to the scale.

Apparatus for mechanical positioning

A woodworking fence includes a dovetail slot into which a stop block and a push fixture each having a dovetail protrusion are in slidable engagement. Operation of a thumbscrew extending through the stop block wedges the block protrusion into firm fixed engagement with the fence dovetail slot. A bottom section of the stop block is undercut to form a relieved space which prevents accumulation of chips resulting from a cutting operation. A workpiece is pushed into a cutter by the push fixture which slides along a work surface and is kept in alignment by the push fixture dovetail protrusion sliding in the fence slot. The push fixture is relieved away from the work surface to avoid damage to the push fixture as the cutting tool cuts the portion of the workpiece adjacent to the push fixture. An erasable polycarbonate strip is disposed on the fence and has a permanent arrow locating the center of the cutting tool, to assist in locating the workpieces and stop block.

A template system has a series of individual joint-forming templates partially die-cut in a transparent flexible plastic sheet reverse-side printed with a series of linear indicia parallel to each other indicating the position of each cut to be made in a first workpiece. A second series of linear indicia parallel to each other and different in physical appearance in color, line weight or line type, dotted or solid, than the first series of indicia, indicate the position of each cut to be made in a second workpiece. The executed cuts on the two workpieces results in an interfitted joint between the workpieces such as a dovetail or box joint. A number of bands or templates are contained on a plastic sheet which are adhesively mounted on a paper substrate. A full die cut is provided at one end of the strip forming a lift tab which is used to aid in shearing off the partially die-cut strip from a matrix of other strips also partially die cut, so that the individual template strip reference and edge can be mounted in a positioning jig or on a tool work surface at a reference position dictated by the position of the tool bit and the cutting apparatus fence. The jig and/or the cutting fence is then moved in accord with the indicia markings on the strip for each cut to be made on both workpieces in seriatim.
