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 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. In another embodiment the apparatus is in the form of a pair of rods which are inserted through pairs of holes formed in the support legs and upright members at the desired elevations. In a third embodiment, the apparatus includes a pair of pins fixed to the support legs and positioned to slide in a vertical direction in slots formed in the upright members. Lever arms having notches corresponding to the desired elevations are positioned in the upright members to be engaged by and to support the pins. In each embodiment, the yokes can be disengaged from their respective members so that the way tubes may be pivoted to a vertical position.

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.

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 saw guard system adapted to be mounted on the headstock quill of a multipurpose woodworking tool includes a rear portion adapted to be clamped to the headstock quill, a front portion which forms a pocket with the rear portion and is adjustable so that the pocket size can be varied to accommodate rotary tools of varying thicknesses, and an exhaust port communicating with the pocket and having an outer end adapted to be attached to a vacuum hose. The rear portion supports a riving knife adapted to extend above an associated saw table and which includes an upper saw guard. The riving knife is positioned in a common plane with a rotary tool mounted on the quill, and is capable of remaining closely adjacent to the rotary tool regardless of table position or quill extension. An anti-kickback device includes a finger having a downwardly-extending point and is connected to the riving knife by a pair of link arms so that the horizontal orientation of the finger remains constant regardless of its elevation relative to the riving knife. To facilitate retention of dust in the pocket, as well as its removal through the port, the front portion includes a transverse channel at its lower end communicating with the port, the rear portion includes a deflector plate above the port, and the port is skewed relative to the front portion and is located at a downstream side of the pocket.

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 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 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.
