Abstract: A workpiece support system for a power tool, preferably a multipurpose woodworking tool of the type having a frame, a main table mounted on the frame, and a power-driven tool member associated with the main table. The support system comprises a first pair of tubular rails attached to longitudinal sides of the main table, a pair of extension rods telescoping within the rails, an auxiliary table having a second pair of rails attached thereto which telescope over and are supported by the protruding portions of the rods. The support system includes capstan screws for releasably locking the extension rods to the pairs of rails. The system may include at least one secondary table mounted on the frame and having a third pair of rails telescoping over ends of the protruding portions and including similar locking means. Another embodiment includes a side frame for supporting long workpieces.

Abstract: A multipurpose woodworking tool of the type having a frame, a pair of parallel way tubes extending longitudinally of the frame, and a headstock mounted on the way tubes in which the improvement comprises a pair of yokes joining the way tubes together at ends thereof, pairs of upright members at the ends of the frame and spaced apart to receive one of the yokes therebetween, and an apparatus extending between the yokes and the upright members which enables the way tubes to be changed in elevation between a lower elevation optimal for utilizing a table saw attachment mounted on the way tubes and a higher elevation optimal for utilizing a lathe attachment. In one embodiment, the apparatus includes spring-loaded pins which are sidewardly displaceable from the yokes, and holes positioned at at least two elevations on the upright members to be engaged by the pins.

Abstract: A cutter head system for a woodworking tool in which one or a plurality of discrete cutter segments may be mounted on a shaft of a selected length to form a cutter head for either a jointer, a planer or a molding cutter. Each segment has a plurality of slot portions spaced about its outer periphery and is adapted to be mounted on a shaft so that the slot portions of ganged segments form continuous slots which are substantially coextensive with the segments. A plurality of blade members are positioned within and are coextensive with the slots, wedge plates are positioned within the slots for releasably securing the blade members against the cutter segments, and mounting screws urge the wedge plates against the blade members. Sets of blade members and wedge plates of varying length are used which correspond in length to the length of the slots formed by the segments.
Abstract: A table assembly for a multipurpose tool is used in combination with a tool of the type having a frame, a pair of parallel way tubes mounted on the frame, a headstock mounted on the frame having a motor driven spindle, and releasable pivots which allow the way tubes to be pivoted about their ends to a substantially vertical positions. The table assembly includes a table top, a pivot mounted beneath the table top, a pair of support legs having racks on opposite sides thereof and attached to the pivot, and a carriage, mounted on the way tubes, having channels to receive the support legs. A pair of pinion gears are positioned within the channels to mesh with the racks and are driven by a crank having a locking mechanism so that the table can be displaced relative to the carriage.
Abstract: A tilting table for a woodworking tool comprising a support member, a pair of trunnions pivotally attached to the support member for movement about a common axis, a table top attached to and supported by the trunnions, a pair of wedge blocks mounted to slidably engage the trunnions and support member, and carried on a rod having a nut threaded thereon such that inward displacement of the nut urges the wedge blocks toward each other, thereby jamming the wedge blocks between the trunnions and the support member. The wedge blocks are spring loaded such that outward displacement of the nut allows the wedge blocks to be urged outwardly from their jamming engagement, thus permitting the table top and trunnions to be pivoted relative to the support member.
Abstract: A straddle block is used with a table saw having a rip fence, and consists of a body having a substantially vertically extending fixed leg, a bridge extending from the fixed leg, an adjustable leg attached to and vertically displaceable relative to the bridge. The vertically adjustable leg may be reversed for right or left-handed use, and has opposing, substantially horizontal, rectilinear edges for engaging an upper surface of a piece of stock to be cut on the table saw, and opposing outwardly extending step portions adjacent an end of each rectilinear edge for engaging the trailing end of the stock as it is pushed across the saw table. The bridge spaces the fixed leg from the adjustable leg sufficiently to receive a rip fence therebetween such that the straddle block may slidably engage the rip fence without skewing relative thereto.
Abstract: A planer adapted to be mounted on a multipurpose woodworking tool which includes a housing, a rotating blade driven by the headstock of the tool, and a vertically displaceable table mounted beneath the blade. The table is supported by a plurality of jack screws mounted on the housing and attached to the table by connector nuts which eliminate binding as the table is raised or lowered. The jack screws are driven by a chain drive having an adjustable idler sprocket which permits the chain to be disengaged from a selected jack screw to allow it to be rotated to level the table. Vertically displaceable feed roller assemblies are attached to the housing and each includes a sprocket meshing with a common drive sprocket with sufficient engagement to be driven throughout the vertical displacement of the rollers. A chip removal hood is mounted on the housing and has an exhaust nozzle adapted to receive a vacuum cleaner hose. The planer is releasably mounted to the woodworking tool by a pair of clamps.
Abstract: An adjustable featherboard is used with a table saw or other tool of the type having a substantially flat saw table having at least one groove formed in its surface and a blade slot adjacent and parallel to the groove, and consists of a body having a plurality of angularly extending elongated fingers and a pair of transverse and substantially parallel slots therethrough; a pair of mounting bolts, each positioned in a different one of the slots and having a threaded shank, a flared lower end, and a knob threaded on an upper end of the shank; and an expansion bar extending beneath the slots and sized to engage slidably the groove in the saw table and having a pair of bores therethrough which receive the flared ends of the mounting bolts.
Abstract: A planer of the type adapted to be mounted on and driven by a multipurpose woodworking tool includes a housing, a rotating blade member, and a table mounted beneath the blade member and vertically displaceable relative thereto by a plurality of jack screws. The jack screws carry connector nuts having outer members attached to the table which allow relative sideward movement between the table and screws to minimize table binding. A chain drive engages the jack screws and includes an idler sprocket which can be adjusted to allow adjustment of an individual jack screw to level the table. First and second roller assemblies upstream and downstream of the blade member are rotatably mounted on the housing and are vertically displaceable; the roller assemblies are driven by a single, fixed drive sprocket which is capable of rotating the rollers throughout a range of vertical displacement.
