A wood working assembly for use in preparing and finishing wooden surfaces for shaping and joining wooden members with portable hand tools including a frame sub-assembly, tool support means, including means for supporting and directing a portable hand tool thereupon, and a work board sub-assembly operatively associated with the frame sub-assembly to support a work piece relative thereto and selectively position said work piece relative to the hand tool to shape, form and/or join the work piece therewith.

In conventional fabrication manufacture the thickness of the steel plates are often determined by the metal section required at the weld joints. The subject apparatus and method overcomes this problem by selectively forming a thickened edge along the edge of a thinner steel plate which can now be limited to the thickness required to withstand the stresses on the fabrication. The thickened edge is produced by passing a plate supported on a table through a forming apparatus having a forming roller. The table is movable in an oblique direction relative to the plate so that the shape of the thickened edge may be varied. The forming apparatus and table are automatically controlled to produce a thickened edge of a desired shape intermittently or continuously along a linear or non-linear edge of the plate.

An end preparation tool for pipe fittings includes an end preparation tool having a rotary cutting head with shaping bits carried thereon mounted on a base that also carries a universal clamping fixture for pipe fittings having end openings to be machined in preparation for welding. The clamping fixture includes workpiece engaging clamping pads that permit adjustment of the position of the workpiece relative to a pair of opposed clamping plates that normally secure the pipe fitting in place relative to the cutting head of the end preparation tool. The clamping fixture includes adjustment features that enable the fixture to be moved transversely relative to the cutting head, along the rotary axis of the cutting head and about a vertical axis that permits indexing of the clamping fixture relative to the tool cutting head. The workpiece engaging pads are disposed in an array that extends along a square and diagonal pattern of intersecting lines, and along lines perpendicular to the square lines between their intersections. By locating workpiece engaging pads in such a geometric array, virtually all conventional fittings can be accommodated between the clamping pads comprising the clamping fixture using a minimum number of pad elements. Several embodiments of clamping pads are described.

Contouring of a stack of one or more circuit boards is effected by first partially cutting the contour, leaving a portion of the contour long enough to ensure the rigidity of the circuit with respect to the board. The circuit is then clamped, while the remaining portion is cut without any discontinuity in the cutting. The machine comprises an operating head and a workpiece pressing pad which is operated for clamping the circuit during the cutting of the remaining portion of the contour. The pad is movable with respect to the head in a direction parallel to the uncut portion of the contour for displacement at least equal to the length of such portion. After the cut, as the head is raised, the pad is returned to rest position by the camming action of a roller against a sloping edge.

A woodworking fixture for positioning and guiding a workpiece under a stationary routing head, whereby the workpiece is subject to a composite movement as it progresses under the routing head. The fixture comprises an indexing table having a clamp for securing the workpiece thereon, mounted on a moveable carriage. The indexing table can be slanted at an adjustable angle and may be rotated as the carriage progresses under the routing head in order to create designs of varying depth into the workpiece.

The table together with the workpiece is imparted vertical motion in such a manner that its bearing points lying at the vertices of an imaginary parallelogram, move equal distances only in pairs constituted by the adjacent bearing points. To this end the bed of the table has four bearing members located at the vertices of an imaginary parallelogram and adapted for vertically changing the position of any pair of the adjacent bearing members with respect to the bed, with the result that the workpiece together with the table is set spatially true with respect to the machine operative unit.
