摘要： A power module for providing power to any one of a plurality of special purpose woodworking tools has a variable speed headstock on a base, and a tool support carriage on the base. The tool support carriage is formed with two pairs of tube-receiving sockets for receiving the support tubes of a special purpose woodworking tool. The sockets are formed at two different levels above the base, such levels corresponding to the difference in spacing of the input shaft connections with respect to the support tubes. The base is mounted for movement toward and away from the headstock, providing alignment of the input shaft with the headstock hub. A variable speed drive in the headstock employs an intermediate three-section pulley of the variator type, and a speed control knob is connected to position the variable speed drive to provide for the selection of speed for any particular tool.

摘要： A scroll saw has a base including integral walls forming a gear casing, a frame assembly mounted on the base, and lower and upper oscillating arm members pivotally mounted on the frame assembly. The gear casing houses gear and counterweight assemblies for driving and counterbalancing the oscillating motion of the lower and upper arm members. A saw blade is removably mounted between corresponding free ends of the lower and upper reciprocating arm members. The ends of the saw blade are prepositioned between a pair of blade holders, and the entire assembly of blade and blade holders is then attached as a unit to the free ends of the arm members. Blade tension is adjusted by means of a tensioning system that indexes blade tension to rotation of a tension knob. The saw further includes a nonflexible tube which functions as a combination airblaster and blade guard for directing an air stream into a cutting area to remove sawdust and other debris while preventing accidental contact with the saw blade.

摘要： A biscuit joiner for cutting semi-elliptical slots in opposing edges of workpieces which are to be joined along those edges includes a housing adapted to be mounted upon the quill of a multi-purpose woodworking tool, which housing encloses a rotary saw blade adapted to be attached to a spindle projecting from the quill on which the housing is mounted. A spring loaded guide projects from the front face of the housing and has a slot therethrough, so that when the front face of the guide is engaged by an edge of a workpiece to be slotted the guide can be pushed inwardly against spring pressure, allowing the rotary saw blade to be exposed and form a slot in the edge of the workpiece. Adjustable stops are provided on the guide so that a desired depth of cut will automatically be made after adjustment.

摘要： 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. The combination of the main table, auxiliary table and secondary table provides a rigid, level and adjustable workpiece supporting surface.

摘要： 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. A chip removal hood is mounted on the housing and has an exhaust nozzle adapted to receive a hose of a vacuum cleaner to draw chips through the hood. A pair of clamping members are attached to side walls so that the blade member and an output shaft of a head stock of the woodworking tool are coaxial, whereby a coupling member may be used to transmit rotary power therebetween. A switching device includes a master switch that controls the flow of electric current to both the head stock and the electric motor driving the feed mechanism, and includes a key-operated locking mechanism.

摘要： A combined tensioning and tracking assembly is provided for use with band saw tools. A continuous saw band is supported by three spaced-apart pulleys. A bar, supporting one of the pulleys, is mounted for sliding and tilting movement, with the sliding movement providing adjustment in the tension of the saw band, and the tilting movement providing adjustment in the "tracking" of the saw band. The sliding movement of the bar is accomplished through an overcenter arrangement which tensions and releases the saw band. The bar, over center arrangement, and structure for achieving sliding and tilting movement of the bar, are all attached to a bracket which is mounted on the frame of the band saw tool.
