Abstract: A retractable registration pin to be used on the tooling plate of a printed wire board drilling machine for alignment of PWB panels on the tooling plate for drilling. In the instant invention, a soft plug which receives a registration pin is mounted on a spline shaft. The bottom of the ball spline shaft is attached to a link which is coupled to a pneumatic cylinder. The pneumatic cylinder is driven by a pneumatic valve which raises and lowers the registration pin on the ball spline assembly. The pneumatic cylinder may either fully retract the registration pin to a position below the surface of the tooling plate, or fully extend the ball spline shaft so that the upper surface of the soft plug holding the registration pin, is parallel to and lies in the same plane as the upper surface of the tooling plate. When the registration pin is in the raised position, work panels may be placed over the registration pin until a suitable number have been prepared for drilling.
Abstract: An adjustable stop mechanism for limiting the movement of a rip fence toward the cutting plane of a tiltable panel saw as an automatic function of the selected orientation of an abutment bar. The abutment bar has first and second orientations alternately presenting an abutment face of relatively low height, located at a greater distance from a reference surface, and a relatively greater height, located at a relatively shorter distance from the reference surface. When the abutment bar is rotated to the low height orientation, as to accommodate tilting of the panel saw blade, a limit stop position of movement of the abutment bar toward the cutting plane is automatically altered, so that the limit stop for the abutment bar support is farther away from the cutting plane. When the bar is oriented to present a full height abutment face, the limit stop automatically is altered in response to such orientation, to permit the support to move closer to the cutting plane.

Abstract: An apparatus for assembling roof trusses including a multi-section assembly table with narrow, parallel, elongated openings in each section. Jig stops are individually adjustable along these openings by respective lead screws driven by stepper motors. The motors are controlled from a computer to automatically position the jig stops in accordance with a particular truss design. The apparatus has conveyor roller carriers between the sections of the assembly table which are raised to lift a completed truss up from the table, so that it can be slid off the table.
Abstract: A truss assembly table having a plurality of sections in succession along its length separated by openings. Each section of the table has several panels in succession separated by openings which extend across the table. Below each opening between the panels, a lead screw drives a carrier which supports a jig stop projecting above the top of the table. Each lead screw is driven by a manually-controlled power-operated device for positioning the corresponding jig stop at a selected position across the table. Power-operated lifts at the openings between sections of the table can be raised to lift a completed truss above the top of the jig stops so that it can be slid off the table laterally.
Abstract: A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a stop member movable along one of the X and Y axes and a clamping element for clamping the workpiece in the stop member for movement therewith.
